The extended subperiosteal face lift: a definitive soft-tissue remodeling for facial rejuvenation.

The subperiosteal face lift described by Psillakis has been criticized for not showing a more dramatic improvement over conventional brow/face lift procedures. His approach also has a significantly high incidence of nerve injury. This study reports our anatomic findings and surgical modifications, which have permitted a significant improvement in the safety of execution and clinical results using the subperiosteal face lift concept. Pertinent points of applied local anatomy and dissection techniques are as follows: First, we use extensive interconnected subperiosteal dissection that includes the entire zygomatic arch. This allows better repositioning of the deep soft tissues of the entire upper face, most of the midface, and indirectly, key structures of the lower face. Second, the upward pull of the muscles of the cheek and mouth will produce an elevation of the corner of the mouth, affecting positively the smiling mechanism, the oral frowning, and the jowls. Third, the dissection deep to both layers of the temporal fascia decreases the risk of injury to the frontalis nerve. Fourth, the temporal fascia is used as a lifter and anchoring element of the entire cheek-perioral soft tissues as opposed to the periorbital fibrofatty tissues. This will decrease the risk of injuring the frontal and zygomatic branches of the facial nerve. These modifications have been used in 28 patients. Our rate of patient satisfaction has been high, and no complications with regard to nerve injury have been observed. This compares favorably with our initial 60 patients, in whom the Psillakis or Tessier approach was used. In these patients, there was an 11 and 20 percent rate of nerve injury, respectively.     

Multiplane face lift with the subperiosteal dissection for orientals

A subperiosteal face lift rejuvenates the midface and periorbital region by restoring facial muscle tone. Since 1993, the authors have performed this procedure on Oriental patients who have their own distinct facial contours: the brachycephalic cranium and a prominent zygoma and mandibular angle. Although it was thought that these protuberances might disturb the subperiosteal procedure, especially in the anterior midface, the procedure could be performed easily by adopting the ancillary upper buccovestibular and subciliary incisions; the authors found that the protuberances actually act as fulcrums to keep up the lifting vectors reliably. For older patients, the procedure was combined with a deep subcutaneous dissection. A simple lift of the periosteum would not improve a severe nasolabial fold deformity and prominent wrinkles adequately because of "lag-lifting" of the superficial layer. It was concluded that the multiplane face lift, consisting of the subperiosteal and the deep subcutaneous approaches, achieves a natural-appearing rejuvenation of the Oriental aging face.     

Dynamic reconstruction of eye closure by muscle transposition or functional muscle transplantation in facial palsy

For patients with facial palsy, lagophthalmus is often a more serious problem than the inability to smile. Dynamic reconstruction of eye closure by muscle transposition or by free functional muscle transplantation offers a good solution for regaining near-normal eye protection without the need for implants. This is the first quantitative study of three-dimensional preoperative and postoperative lid movements in patients treated for facial paralysis. Between February of 1998 and April of 2002, 44 patients were treated for facial palsy, including reconstruction of eye closure. Temporalis muscle transposition to the eye was used in 34 cases, and a regionally differentiated part of a free gracilis muscle transplant after double cross-face nerve grafting was used in 10 cases. Patients' facial movements were documented by a three-dimensional video analysis system preoperatively and 6, 12, 18, and 24 months postoperatively. For this comparative study, only the data of patients with preoperative and 12-month postoperative measurements were included. In the 27 patients with a final result after temporalis muscle transposition for eye closure, the distance between the upper and lower eyelid points during eye closing (as for sleep) was reduced from 10.33 +/- 2.43 mm (mean +/- SD) preoperatively to 5.84 +/- 4.34 mm postoperatively on the paralyzed side, compared with 0.0 +/- 0.0 mm preoperatively and postoperatively on the contralateral healthy side. In the resting position, preoperative values for the paralyzed side changed from 15.11 +/- 1.92 mm preoperatively to 13.46 +/- 1.94 mm postoperatively, compared with 12.17 +/- 2.02 mm preoperatively and 12.05 +/- 1.95 mm postoperatively on the healthy side. In the nine patients with a final result after surgery using a part of the free gracilis muscle transplant reinnervated by a zygomatic branch of the contralateral healthy side through a cross-face nerve graft, eyelid closure changed from 10.21 +/- 2.72 mm to 1.68 +/- 1.35 mm, compared with 13.70 +/- 1.56 mm to 6.63 +/- 1.51 mm preoperatively. The average closure for the healthy side was from 11.20 +/- 3.11 mm to 0.0 +/- 0.0 mm preoperatively and from 12.70 +/- 1.95 mm to 0.0 +/- 0.0 mm postoperatively. In three cases, the resting tonus of the part of the gracilis muscle transplant around the eye had increased to an extent that muscle weakening became necessary. Temporalis muscle transposition and free functional muscle transplantation for reanimation of the eye and mouth at the same time are reliable methods for reconstructing eye closure, with clinically adequate results. Detailed analysis of the resulting facial movements led to an important improvement of the authors' operative techniques within the last few years. Thus, the number of secondary operative corrections could be significantly reduced. These qualitative and quantitative studies of the reconstructed lid movements by three-dimensional video analysis support the authors' clinical concept of temporalis muscle transposition being the first-choice method in adult patients with facial palsy. In children, free muscle transplantation is preferred for eye closure, so as not to interfere with the growth of the face by transposition of a masticatory muscle. In addition, a higher degree of central plasticity in children might be expected.     

Restoring facial shape in face lifting: the role of skeletal support in facial analysis and midface soft-tissue repositioning

Aesthetic analysis in facial rejuvenation has traditionally been subordinate to technical solutions. While concerns regarding correction of facial laxity, a reduction in the depth of the nasolabial fold, and improvement of both the jowl and the jawline are worthy goals in rhytidectomy, the aesthetic concept of restoring facial shape to a more youthful appearance is equally important. Restoring facial shape in face lifting requires an understanding of how the face ages and then the formulation of a treatment plan that is individualized for the patient. Re-establishment of facial contour is significantly influenced by the re-elevation of descended facial fat through superficial musculoaponeurotic system manipulation; it can be approached through a variety of technical solutions. Underlying skeletal support affects not only the appearance of the face in youth but also how the face ages and influences the operative plan in terms of the requirements for fat repositioning. Formulating a treatment plan that is patient specific and based on the artistic goals as influenced by skeletal support is the key element for consistency in restoring facial shape in face lifting.     

Partial lip resection with orbicularis oris transposition for lower lip correction in unilateral facial paralysis.

Malfunction of the marginal mandibular nerve, either in combination with a generalized facial palsy or in isolation, can cause an unpleasant and disturbing appearance around the mouth. In total palsy, a cross-facial nerve graft combined with a free vascularized muscle transplant will usually deal with this problem successfully; however, all older procedures used in this situation are unpredictable. For the isolated palsy, procedures such as digastric muscle transfer or sling suspension are not uniformly successful. A method using the contralateral, nonaffected lower lip orbicularis muscle is described. A wedge is removed from the paralyzed lower lip and the orbicularis is advanced to the modiolus to provide a functional orbicularis all the way across the lower lip up to the angle of the mouth. This is a simple outpatient procedure that has produced satisfactory results in most cases.     

Results of management of facial palsy with microvascular free-muscle transfer

This paper reports our experience in facial reanimation using free innervated muscle transfer in 69 patients with long-term facial palsy. The majority of patients were treated in two stages with cross-facial nerve graft as the first stage and microvascular muscle transfer at the second stage. The gracilis muscle was used in 62 patients. A system of grading results has been utilized in the long-term evaluation. The overall final result was excellent or good in 51 percent of 47 patients who were available for follow-up. Although the results are not completely satisfactory, they justify the use of this approach to a difficult clinical problem. The results are improving as technical modifications to the procedure have evolved. The gracilis muscle is a reliable free transfer with internal anatomy conductive to use for reanimation of the paralyzed face. This type of transfer, in our experience, has proved superior to nonmicrosurgical methods for treatment of complete and severe incomplete facial palsy. The seventh cranial nerve is used in the innervation of the transferred muscle, the ipsilateral being preferable if available. The authors believe that use of the same cranial nerve is superior to methods that involve other cranial nerves, where spontaneity is often not achieved.     

Selective myectomy for postparetic facial synkinesis

Synkinetic movements are secondary to facial palsy because they appear like a late sequela to spontaneously healing facial nerve injury. They are produced by an involuntary contraction of a muscle group simultaneous with contraction of other homologous muscle groups. The disorderly regeneration of severed axons is responsible for these movements. According to the Lippschitz theory, the regenerating nerve fibers sprout into the wrong peripheral branches. Between 1975 and 1986, 71 patients with facial paralysis were evaluated. Spontaneous recovery from the facial paralysis occurred in 28 of these patients; 14 (50 percent) developed synkinetic movements, and surgical treatment was sought by only 6 patients. In all patients, the lesion of the facial nerve was in the trunk, proximal to the principal ramification. The most frequent clinical finding was simultaneous activation between the orbicularis oculi and the elevators of the corner of the mouth (12 patients) or the elevators of the upper lip (2 patients). In 8 patients, in whom the slight synkinesis was not noticed by the patients, surgical correction was not necessary, but in the other 6 patients with severe aesthetic disturbances, surgical treatment for "disconnection" of the wrong impulses was realized. I obtained this "disconnection" through resection of the involved perioral muscle groups instead of paralysis of the orbicularis oculi. Follow-up of the 6 patients operated with the surgical treatment proposed herein for between 4 and 8 years has shown good aesthetic results without functional or aesthetic sequelae.     

Botulinum toxin: a treatment for facial asymmetry caused by facial nerve paralysis

Injury to the frontal or other facial nerve branches can result in an asymmetry that can be very distressful to both patient and surgeon. This is especially true following cosmetic procedures such as rhytidectomy. We propose a means to create temporary symmetry while awaiting the possible return of nerve function. Botulinum neurotoxin causes a muscle paralysis lasting for approximately 3 months, and it is well established as the preferred treatment for blepharospasm. A case is presented in which botulinum toxin type A was injected into the opposite functioning frontalis muscle of a patient with unilateral frontal nerve paralysis. The patient experienced satisfactory relief of the asymmetry caused by onesided forehead wrinkling and brow elevation. Botulinum toxin therapy should be considered for both temporary and permanent facial asymmetries due to facial nerve paralysis as well as spasm.     

The pectoralis minor vascularized muscle graft for the treatment of unilateral facial palsy

A series of 10 pectoralis minor vascularized muscle transfers to reanimate the face in unilateral facial palsy are presented. The procedure is carried out in two stages. The first stage constitutes a nerve graft from the functional contralateral facial nerve to the preauricular region of the paralyzed side. Six months later, the pectoralis minor is transferred to the denervated side of the face with restoration of its neurovascular pedicle. The muscle is well suited to its new position with respect to length and bulk, as well as its fanlike shape. The diameter of its vascular pedicle is comparable with the facial vessels. The results demonstrate function in 8 of the 10 grafts, the two failures relating to early vascular thrombosis rather than an inability to reinnervate the muscle grafts.     

Refinements in face lifting: enhanced facial contour using vicryl mesh incorporated into SMAS fixation

As we have gained experience with the extended superficial musculoaponeurotic system (SMAS) technique in face lifting, refinements in our procedure have led to increased consistency in results. The important factors that have led to our technical modifications include the following: (1) the significance of the retaining ligaments of the midface, which determine the degree of surgical dissection required for both skin and SMAS in rhytidectomy; (2) the changes in facial shape that occur with aging, secondary to the descent of facial fat; (3) the possibility of modifying facial shape through the repositioning of facial fat in an extended SMAS face lift; (4) the improved longevity of result to be obtained by incorporating Vicryl mesh into SMAS fixation; (5) the artistic nuances of incision design that help to minimize scar perceptibility. Understanding these factors enables surgeons to use the extended SMAS technique successfully with more challenging cases, enhancing facial appearance while minimizing signs that the patient has undergone a surgical procedure.     

Three-dimensional video analysis of facial movements: a new method to assess the quantity and quality of the smile

The results of neuromuscular reconstructions of the paralyzed face are difficult to assess. Very sophisticated methods are necessary to measure the motor deficits of facial paralysis or the functional recovery in the face. The aim of this development was a relatively simple system for data acquisition, which is easy to handle and which makes it relatively cheap to delegate data acquisition to centers all over the world, which will not be able to derive a data analysis on their own, but will send their data to a center with specialized equipment. A complex mirror system was developed to get three different views of the face at the same time on the video screen. At each investigation, a digital video is taken from a calibration grid and from standardized facial movements of the patient. Secondary analysis of the digital videofilm is made possible at any time later on by the support of a computer program, which calculates distances and movements three-dimensionally from the frontal image and the right and left mirror images. Pathologies of the mimic movements can be identified as well as improvements after surgical procedures by this system. The significant advantage is the possibility to watch the same movement on the video which is under study and to apply any kind of study later on. Taking the video needs only a few minutes, and fatigue of the patient's mimic system is prevented. Measurements usually at the endpoints of the movements give excellent information on the quantity of the movement or the degree of the facial palsy, whereas the video itself is very informative regarding the quality of the smile. Specific computer software was developed for standardized three-dimensional analysis of the video-documented facial movements and for data presentation. There are options like two-dimensional graphs of single moving points in the face or three-dimensional graphs of the movements of all measured points at the same time during a standardized facial movement. By a comparison of the right- and left-sided alterations of specific distances between two points during the facial movements, the degree of normal symmetry or pathologic asymmetry is quantified. This system is more suitable for detailed scientific multicenter studies than any other system previously established. A very sensitive instrument for exact evaluation of mimic function is now available.     

Neurovascular free-muscle transfer to treat facial paralysis associated with hemifacial microsomia

Despite the wide spectrum of hemifacial microsomia manifestations, treatment mainly focuses on mandible and ear abnormalities, rather than on facial paralysis. In fact, the surgical treatment of facial paralysis associated with hemifacial microsomia is quite underdeveloped, because the degree of paralysis is frequently incomplete or partial. Timing and type of surgery are also difficult to determine. Neurovascular free-muscle transfer is now a standard procedure for the dynamic smile reconstruction of longstanding facial paralysis. This type of strategy has considerable potential in the treatment of facial paralysis in patients with hemifacial microsomia. We present here our experience with neurovascular free-muscle transfer for smile reconstruction in eight patients with facial paralysis associated with hemifacial microsomia. The age of the patients at the time of surgery ranged from 7 to 28 years old, (average, 13.9 years). Six were male patients and two were female patients. The two-stage method combining gracilis muscle transfer with cross-face nerve grafting was performed in three patients, whereas the one-stage transfer of the latissimus dorsi muscle was performed in five. To construct a natural or near-natural smile, the muscles were transferred into the paralyzed cheek in all except one patient, in whom the latissimus dorsi muscle was transferred into the sublabial area to reconstruct a paralyzed lower lip. A dermal flap segment vascularized with perforating vessels from the latissimus dorsi muscle was simultaneously inserted into the underdeveloped cheek for soft-tissue augmentation in this patient. Muscle contraction was evident in all patients between 4 and 8 months after muscle transfer. Our present series revealed that neurovascular free-muscle transfer is a good option not only for smile reconstruction but also for restoration of the facial contours of patients with hemifacial microsomia. Compared with the two-stage method combining gracilis muscle transfer with cross-face nerve grafting, the one-stage method using the latissimus dorsi muscle has some advantages, including a one-stage operation, a shorter recovery period, and the absence of sequelae that occur after harvesting a sural nerve.     

Neurovascular musculus obliquus internus abdominis flap free transfer for facial reanimation in a single stage

A study of the anatomy and transplantation of the musculus obliquus internus abdominis with a neurovascular pedicle transfer for facial reanimation in one stage is presented. Eleven adult cadavers (22 face sides) were dissected to observe the shape, thickness, innervation, and blood supply of the musculus obliquus internus abdominis. The blood supply of this muscle primarily comes from the musculus obliquus internus abdominis branch of the deep circumflex iliac artery (diameter, 1.3 +/- 0.2 mm), but it can also come from the eleventh intercostal artery (diameter, 1.14 +/- 0.3 mm) and the infracostal artery (diameter, 1.5 +/- 0.2 mm). The branch of the deep circumflex iliac artery and its vena comitans, or the infracostal artery and its vena comitans, could be anastomosed for muscle transplantation. The innervation of the musculus obliquus internus abdominis comes from the tenth and eleventh intercostal nerves (length, 12.7 +/- 1.5 cm) and the infracostal nerve (length, 12.9 +/- 1.3 cm). The eleventh intercostal nerve and the infracostal nerve were selected for anastomosis of muscle transplantation. From November of 1995 to November of 1999, 14 patients with long established facial paralysis were treated with transplantation of a musculus obliquus internus abdominis flap in one stage and were followed for 10 months to 6 years. In 13 patients, the dynamic functions of the transplanted muscles were restored, the obliqueness of the mouth and philtrum while static was corrected, and the facial muscle activities while smiling were harmonized. The eyelids of the paralyzed side could be closed postoperatively, indicating that the function of the orbicularis oculi of the paralyzed side was restored. The single-stage transplantation of a free musculus obliquus internus abdominis flap with one vascular, multi-nerve pedicle is a new method for facial reanimation in the treatment of long established facial paralysis. Because of the simplicity of the procedure and the completeness of the functional reanimation of the paralyzed facial muscles, compared with the results of other free muscle flap transfers, it is an ideal procedure for facial reanimation.     

Neurovascular free-muscle transfer for the treatment of established facial paralysis following ablative surgery in the parotid region

Neurovascular free-muscle transfer for facial reanimation was performed as a secondary reconstructive procedure for 45 patients with facial paralysis resulting from ablative surgery in the parotid region. This intervention differs from neurovascular free-muscle transfer for treatment of established facial paralysis resulting from conditions such as congenital dysfunction, unresolved Bell palsy, Hunt syndrome, or intracranial morbidity, with difficulties including selection of recipient vessels and nerves, and requirements for soft-tissue augmentation. This article describes the authors' operative procedure for neurovascular free-muscle transfer after ablative surgery in the parotid region. Gracilis muscle (n = 24) or latissimus dorsi muscle (n = 21) was used for transfer. With gracilis transfer, recipient vessels comprised the superficial temporal vessels in 12 patients and the facial vessels in 12. For latissimus dorsi transfer, recipient vessels comprised the facial vessels in 16 patients and the superior thyroid artery and superior thyroid or internal jugular vein in four. Facial vessels on the contralateral side were used with interpositional graft of radial vessels in the remaining patient with latissimus dorsi transfer. Cross-face nerve grafting was performed before muscle transfer in 22 patients undergoing gracilis transfer. In the remaining two gracilis patients, the ipsilateral facial nerve stump was used as the primary recipient nerve. Dermal fat flap overlying the gracilis muscle was used for cheek augmentation in one patient. In the other 23 patients, only the gracilis muscle was used. With latissimus dorsi transfer, the ipsilateral facial nerve stump was used as the recipient nerve in three patients, and a cross-face nerve graft was selected as the recipient nerve in six. The contralateral facial nerve was selected as the recipient nerve in 12 patients, and a thoracodorsal nerve from the latissimus dorsi muscle segment was crossed through the upper lip to the primary recipient branches. A soft-tissue flap was transferred simultaneously with the latissimus muscle segment in three patients. Contraction of grafted muscle was not observed in two patients with gracilis transfer and in three patients with latissimus dorsi transfer. In one patient with gracilis transfer and one patient with latissimus dorsi transfer, acquired muscle contraction was excessive, resulting in unnatural smile animation. The recipient nerves for both of these patients were the ipsilateral facial nerve stumps, which were dissected by opening the facial nerve canal in the mastoid process. From the standpoint of operative technique, the one-stage transfer for latissimus dorsi muscle appears superior. Namely, a combined soft-tissue flap can provide sufficient augmentation for depression of the parotid region following wide resection. A long vascular stalk of thoracodorsal vessels is also useful for anastomosis, with recipient vessels available after extensive ablation and neck dissection.     

Brow suspension,a minimally invasive technique in facial rejuvenation

People tend to prefer noninvasive or minimally invasive methods of facial rejuvenation, especially when it involves their face, which is the hallmark of a person's identity and impossible to hide. It is widely known that brow ptosis gives the face a "tired look" and also accentuates deformities of the upper eyelid. Most people who are interested in facial rejuvenation may not accept even a minor surgery, such as an endoscopic surgery. The senior author has developed a minimally invasive method of suspending the brow at a higher position. In this technique, there is neither surgical dissection nor a surgical incision except for four stab incisions and suture insertion, which is why we refer to it as a nonsurgical brow suspension. It is done under local anesthesia, and the brows are fixed in the position that they assume when the patient is supine. In the past 6 years, we performed 387 brow suspensions on 324 female and 63 male patients. The youngest patient was 19 years old, and the oldest was 74 years old. A retrospective chart review was done. These 387 cases were reviewed by comparison of preoperative and postoperative photographs. This approach was not only used for patients who were not interested in surgical rejuvenation but was also combined with lipofilling, laser resurfacing, and/or upper blepharoplasty. This technique is useful for correcting postsurgical brow asymmetry. We present this technique as an adjunct to the established techniques of facial rejuvenation. Despite the high patient acceptance and technical ease, it is not a replacement for the established techniques of facial rejuvenation.     

Mandibular distraction in temporomandibular joint ankylosis

Condylar damage during childhood can produce ankylosis and alteration of the mandibular growth. In case of unilateral ankylosis occurring in early childhood, a mandibular hypoplasia of the affected side may develop. The patients have limitation of mouth opening, facial asymmetry, and chin deviation toward the affected side. The aims of this study are to show the use of distraction osteogenesis in mandibular hypoplasia associated with ankylosis and to present our experience with a new therapeutic option for the treatment of mandibular hypoplasia with unilateral ankylosis in the childhood consisting of the association of arthroplasty to treat the ankylosis and mandibular distraction to correct the facial asymmetry, both accomplished in the same surgical procedure. From November of 1996 to November of 1997, three male patients aged 2, 7, and 13 years with mandibular hypoplasia and ankylosis were treated by distraction osteogenesis. An arthroplasty consisting of the resection of the ankylotic block and interposition of a temporalis muscle flap, plus coronoidectomy was done in two of them and mandibular distraction was done in all three patients. Articular functional rehabilitation began on the first postoperative day. Mandibular distraction began on the fifth postoperative day with a rate of 1 mm per day, ending when the facial symmetry was achieved. From the first postoperative day, an increase in the mouth opening was achieved; this increase continued until ending the distraction. The average duration of distraction was 22 days. Average duration of consolidation was 6 weeks. Oral opening increased from 10 mm to 35 mm in the 7-year-old patient, from 9 mm to 27 mm in the 2-year-old patient, and from 14 mm to 38 mm in the 13-year-old patient. To date, oral opening and facial symmetry persist. Osseous mandibular distraction together with arthroplasty offers an excellent new alternative for treatment of patients with mandibular hypoplasia and associated ankylosis, with minimal morbidity and complications.     

Chondrogenesis and myogenesis in micromass cultures of mesenchyme from mouse facial primordia

Summary The face develops from small buds of tissue positioned around the primitive mouth. The chondrogenic and myogenic cell populations contained within these facial primordia in mouse embryos have been investigated in short-term micromass culture. Chondrogenesis occurred in frontonasal mass mesenchyme from E11-E13 embryos, in maxillary mesenchyme from E12.5 embryos and was absent in mandibular mesenchyme. Myogenesis was greatest in mandibular mesenchyme, moderate in maxillary mesenchyme and low in the frontonasal mass. When compared with chick embryos the mouse facial primordia have lower chondrogenic potential, which in the case of the frontonasal mass may be related to the relative outgrowth of the primordia in the two species. Chondrogenesis in the mouse mandibular mesenchyme may be affected by the presence of a large population of odontogenic mesenchyme. The behavior of myogenic cell populations is related to the pattern of the musculature of the face, as the mandible contains the most muscle, the maxilla some, and the frontonasal mass none. However, the presence of myoblasts in early mesenchyme of all primordia may indicate that, as with chick, facial primordia are initially seeded with muscle cells and that the size of the cell population is subsequently controlled according to the development of the musculature within the primordia.     

Three-dimensional rejuvenation of the midface: volumetric resculpture by malar imbrication

The rejuvenation technique of malar imbrication, which avoids dissection in the plane of the seventh cranial nerve, is presented to address the author's altered priorities in midfacial rejuvenation. These priorities target volumetric over tension-based goals in a manner that is simpler, safer, and more sculpturally effective than existing techniques. Volumetric manipulations in the subperiosteal and subcutaneous planes also bring substantial rejuvenation to the periorbital and perioral regions, without lip or lower lid incisions. Fourteen of the 172 patients (8 percent) who underwent consecutive procedures for primary facial rejuvenation suffered temporary upper lip paresis. Other complications were infrequent and limited. One patient underwent reoperation for asymmetry. Increased postoperative swelling and recovery are a necessary consequence of the subperiosteal component, just as increased operative time attends the wide undermining of the subcutaneous component. Despite these liabilities, the author recommends adding volumetric resculpture to the existing conventional tools of soft-tissue displacement under tension and topical resurfacing in pursuit of safer, more effective, and more natural rejuvenation of the aging face.     

Neurovascularized free short head of the biceps femoris muscle transfer for one-stage reanimation of facial paralysis

The single-stage technique for cross-face reanimation of the paralyzed face without nerve graft is an improvement over the two-stage procedure because it results in early reinnervation of the transferred muscle and shortens the period of rehabilitation. On the basis of an anatomic investigation, the short head of the biceps femoris muscle with attached lateral intermuscular septum of the thigh was identified as a new candidate for microneurovascular free muscle transfer. The authors performed one-stage transfer of the short head of the biceps femoris muscle with a long motor nerve for reanimation of established facial paralysis in seven patients. The dominant nutrient vessels of the short head were the profunda perforators (second or third) in six patients and the direct branches from the popliteal vessels in one patient. The recipient vessels were the facial vessels in all cases. The length of the motor nerve of the short head ranged from 10 to 16 cm, and it was sutured directly to several zygomatic and buccal branches of the contralateral facial nerve in six patients. One patient required an interpositional nerve graft of 3 cm to reach the suitable facial nerve branches on the intact side. The period required for initial voluntary movement of the transferred muscles ranged from 4 to 10 months after the procedures. The period of postoperative follow-up ranged from 5 to 42 months. Transfer of the vascularized innervated short head of the biceps femoris muscle is thought to be an alternative for one-stage reconstruction of the paralyzed face because of the reliable vascular anatomy of the muscle and because it allows two teams to operate together without the need to reposition the patient. The nerve to the short head of the biceps femoris enters the side opposite the vascular pedicle of the muscle belly, and this unique relationship between the vascular pedicle and the motor nerve is anatomically suitable for one-stage reconstruction of the paralyzed face. As much as to 16 cm of the nerve can be harvested, and the nerve is long enough to reach the contralateral intact facial nerve in almost all cases. The lateral intermuscular septum, which is attached to the short head, provides "anchor/suture-bearing" tissue, allowing reliable fixations to the zygoma and the upper and lower lips to be achieved. In addition, the scar and deformity of the donor site are acceptable, and loss of this muscle does not result in donor-site dysfunction.
