Achieving aesthetic balance in the brow,eyelids, and midface

An approach to the brow, eyelids, and midface emphasizing release and advancement of the orbicularis oculi muscle, conservative removal of orbital fat, preservation of the nerve supply to the orbicularis oculi muscle, and avoidance of canthal division was evaluated in 100 consecutive patients. The technique describes the selected release of three key retaining ligaments to the forehead, brow, and upper eyelid; mobilization of the lateral retinaculum and division of the lower lid retaining ligament; and division of the midface malar retaining ligament (zygomatic-cutaneous ligament). Preservation of motor branches to the lower lid orbicularis is stressed. Of significance to this series of patients is the inclusion of 50 patients with morphologically prone lower eyelids defined as atonic lower lids, exorbitism, and/or negative vector orbits. Three sites had failure of brow fixation, two patients had midface asymmetry requiring revision, and three patients failed to have complete correction of their preoperative lower lid retraction. There was zero incidence of scleral show or lower lid retraction that was not present preoperatively. No patients required division of the lateral commissure with canthoplasty, taping or suture suspension, massage, or steroid injections. Only two patients required division of the deep head of the lateral canthus, and these patients were noted to have had lateral canthal malposition preoperatively.     

The superficial lateral canthal tendon: anatomic study and clinical application to lateral canthopexy

Most patients who undergo facial cosmetic surgery procedures that could cause lower eyelid retraction or ectropion should have an additional surgical procedure to support the lower eyelid and lateral canthus. The lower eyelid should be supported when performing laser planing of the eyelid; midface elevation through a lower eyelid incision approach; or conventional blepharoplasty, in patients with lower eyelid laxity. Suspending the lateral canthus by surgically altering the lateral canthal tendon is a proven technique that can provide support for the lower eyelid. However, a technique of this complexity may be unnecessary for most cosmetic surgery patients. To increase understanding of the fascial support system of the lateral canthus, four fresh cadaver dissections were performed to investigate the attachments of the lateral canthus to the lateral orbital rim. The most commonly appreciated attachment between the eyelids and the lateral orbital rim is the lateral canthal tendon (the lateral canthal raphe). However, the lateral canthus also is attached to the orbital rim at a more superficial level through the septum orbitale. This superficial fascial plane may be modified and used as a structure to stabilize or suspend the lateral canthus. This structure is defined in this article as the "superficial lateral canthal tendon."     

Transblepharoplasty lower eyelid and midface rejuvenation: part I. Avoiding complications by utilizing lessons learned from the treatment of complications

Transblepharoplasty midface elevation has become a common aesthetic procedure in recent years. As new techniques have been utilized, complications have arisen. Management of these referred complications has resulted in the development of a technique that elevates the midface and restores the normal position and shape to the lower eyelid with minimal postoperative problems. Four principles must be followed to achieve satisfactory results. The orbicularis oculi/orbital septum bond must not be altered in midface surgery. The lateral canthus must be reattached to its normal anatomic location at the lateral orbital rim if there is lateral canthal tendon laxity. The orbital fat should be addressed via a transconjunctival approach, when necessary, to prevent middle lamella inflammation and orbital septum retraction. A suture at the inferior lateral orbital rim simulating the orbitomalar ligament, as well as orbicularis oculi muscle sutures, elevates the midface. Utilizing these steps, the midface and lower eyelid can be satisfactorily repositioned with minimal complications. This surgical approach can be utilized in all appropriate candidates but is especially useful in reoperative cosmetic surgery patients and the older patient population.     

Surgical correction of Tessier number 8 cleft

The number 8 Tessier cleft can be a discrete horizontal shadow at the level of the lateral canthus of the palpebral fissure or a true coloboma with absence of the commissure between the upper and lower eyelids. A surgical technique, which has been used in eight patients, is described to correct this congenital defect. Four flaps are created and transposed as two Z-plasties. The lateral canthal ligament is fixed to the lateral orbital rim, and the orbicularis muscle is interdigitated to restore its continuity. This procedure reconstructs the depth of the conjunctival fornix, provides proper form and length to the palpebral fissure, and restores continuity and an anatomic angle to the malformed canthus.     

Surgical anatomy of the midcheek and malar mounds

The anatomy of the midcheek has not been satisfactorily described to adequately explain midcheek aging and malar mounds, nor has it suggested a logical approach to their correction or provided sufficient detail for safe surgery in this area. This cadaver study, which was complemented by many operative dissections, located a missing link: a glide plane space overlying the body of the zygoma. The space functions to allow mobility of the orbicularis oculi, where it overlies the zygoma and the origins of the elevator muscles to the upper lip. The space is a cleft between the sub-orbicularis oculi fat and the preperiosteal fat and is lined by a fine membrane. The anatomic boundaries are clearly defined by retaining ligaments, which correlate with the triangularity of the space. Several anatomic features provide the functional characteristics of the prezygomatic space, including the (1) absence of direct attachments between the orbicularis in the roof to the floor, (2) more rigid inferior boundary formed by the zygomatic ligaments, and (3) more mobile upper ligamentous boundary formed by the orbicularis retaining ligament (separating from the preseptal space of the lower lid). These components determine the characteristic aging changes that occur in this region and explain much about malar mounds. An appreciation of this anatomy has several surgical implications. The prezygomatic space is a junction area that can be approached from the temple, lower lid, and cheek. The zygomatic branches of the facial nerve to the orbicularis do not cross the space; rather, they course in the walls and in the sub-orbicularis fat within the roof of the space.     

Transblepharoplasty endoscopic subperiosteal midface lift

The use of endoscopy in the transblepharoplasty midface lift is essential for preventing the complications of facial nerve injury and bleeding. Complete observation allows precise dissection and release of all structures in the composite flap. This technique fully preserves the zygo-orbicular nerve plexus and prevents denervation of the orbicularis oculi and zygomaticus muscles. Blind dissection has a significant probability of denervation of the entire zygo-orbital muscle complex, and avulsion of the zygomaticofacial vessels, with associated postoperative bleeding complications. The modification involving suturing of the "vest" of the combined lateral orbital periosteal and superficial layers of the deep temporal fascia over the elevated "pants" of the orbicularis periosteal flap provides very secure fixation for suspension of the lower eyelid and midface. The use of slowly absorbable polydioxanone sutures for this technique prevents the problems caused by permanent sutures beneath the very thin skin of the lateral canthal area. Careful trimming of the prominent roll of the orbicularis muscle that often develops with suspension eliminates the uneven contour and yields a smooth lower lid appearance. The details and modifications described should decrease the complications and morbidity that can occur with this procedure and provide for a more precise and reliable procedure for rejuvenation of the lower eyelid and midface.     

Restoring palpebral fissure shape after previous lower blepharoplasty

The youthful palpebral fissure can be described as long and narrow. Both the aging process and transcutaneous lower blepharoplasty can cause descent of the lower lid margin and medial migration of the lateral canthus, resulting in a rounding of the palpebral fissure. This article presents a technique to correct significant postsurgical lower lid malposition and palpebral fissure distortion without the use of outer or inner lamellar grafts. In overview, subperiosteal dissection frees scarred lid structures and cheek soft tissues, creating a continuous composite flap. Elevation of the cheek soft tissues recruits deficient outer lamellae and allows the sub-orbicularis oculi fat to be positioned between the orbital rim and scarred lid structures, filling this space and helping to support the repositioned lid margin. Titanium screws placed in the lateral orbit provide a point for secure fixation of elevated cheek tissues. Transosseous wire fixation securely repositions the lateral canthus. This procedure not only restores lower lid position and the vertical height of the palpebral fissure, but it also restores the palpebral fissure's horizontal length and the lateral canthal angle. It has been effective in correcting palpebral fissure distortion after lower blepharoplasty in 15 patients during a 6-year period.     

The relationship of the superficial and deep facial fascias: relevance to rhytidectomy and aging.

Controversy persists regarding the relationship of the superficial facial fascia (SMAS) to the mimetic muscles, deep facial fascia, and underlying facial nerve branches. Using fresh cadaver dissection, and supplemented by several hundred intraoperative dissections, we studied facial soft-tissue anatomy. The facial soft-tissue architecture can be described as being arranged in a series of concentric layers: skin, subcutaneous fat, superficial fascia, mimetic muscle, deep facial fascia (parotidomasseteric fascia), and the plane containing the facial nerve, parotid duct, and buccal fat pad. The anatomic relationships existing within the facial soft-tissue layers are (1) the superficial facial fascia invests the superficially situated mimetic muscles (platysma, orbicularis oculi, and zygomaticus major and minor); (2) the deep facial fascia represents a continuation of the deep cervical fascia cephalad into the face, the importance of which lies in the fact that the facial nerve branches within the cheek lie deep to this deep fascial layer; and (3) two types of relationships exist between the superficial and deep facial fascias: In some regions of the face, these fascial planes are separated by an areolar plane, and in other regions of the face, the superficial and deep fascia are intimately adherent to one another through a series of dense fibrous attachments. The layers of the facial soft tissue are supported in normal anatomic position by a series of retaining ligaments that run from deep, fixed facial structures to the overlying dermis. Two types of retaining ligaments are noted as defined by their origin, either from bone or from other fixed structures within the face.(ABSTRACT TRUNCATED AT 250 WORDS)     

Laser blepharoplasty with transconjunctival orbicularis muscle/septum tightening and periocular skin resurfacing: a safe and advantageous technique

Carbon dioxide (CO2) laser blepharoplasty with orbicularis oculi muscle tightening and periorbital skin resurfacing is a safe procedure that produces excellent aesthetic results and diminishes the occurrence of complications associated with skin and muscle resection in the lower lid, particularly permanent scleral show and ectropion. The authors present a review of 196 cases of carbon dioxide laser blepharoplasty and periocular laser skin resurfacing performed at their center from April of 1994 to September of 1998. Of these cases, 113 patients underwent four-lid blepharoplasty, 59 underwent upper lid blepharoplasty only, and 24 underwent lower lid blepharoplasty only. Prophylactic lateral canthopexy was performed in 24 patients. Concomitant procedures (brow lift/rhytidectomy/rhinoplasty) were performed in 92 patients. The carbon dioxide laser blepharoplasty procedure resulted in no injuries to the globe, cornea, or eyelashes. Combined with laser tightening of the orbicularis oculi muscle and septum and periocular skin resurfacing, the transconjunctival approach to lower blepharoplasty preserves lower lid skin and muscle. Elimination of the traditional scalpel skin/muscle flap procedure results in a dramatically lower complication rate, particularly with regard to permanent ectropion and scleral show. Laser shrinkage of the orbicularis muscle and septum through the transconjunctival incision enables the correction of muscle aging changes such as orbicularis hypertrophy and malar festoons. The addition of periocular resurfacing enables the correction of skin aging changes of the eyelid that are not addressed by traditional scalpel blepharoplasty. In addition, lateral canthopexy constitutes an important adjunct to the laser blepharoplasty procedure for the correction of lower lid canthal laxity.     

Selective alteration of palpebral fissure form by lateral canthopexy

A method is described for altering the shape and position of the palpebral fissure at the lateral canthus. Three steps are essential to alter shape and position. They are (1) identification of a lateral canthal soft-tissue mass consisting of periosteum, lateral canthal ligament, and orbicularis muscle, (2) extensive subperiosteal soft-tissue mobilization of the lateral canthal soft-tissue mass (LCSTM) from a point just superior to the zygomaticofrontal suture and inferiorly along the infraorbital rim to a point corresponding with a vertical line drawn from the pupil downward, and (3) cutting of all soft tissue, including orbicularis muscle from dermis to bone and from bone to conjunctiva, from the lateral canthal soft-tissue mass medially to a point equal to a vertical line drawn from the pupil downward. After tension-free shifting laterally and superiorly has been accomplished, the lateral canthal soft-tissue mass is fixed into bone with minimal overcorrection. If there is still soft-tissue skin resistance, then overcorrection is desirable. The most difficult judgments in the procedure are the amount of superior and lateral tension to be placed on the palpebral fissure. As an aid in these judgments, the lateral-most extent of the palpebral fissure should be approximately 3 mm above the medial canthus horizontally and 3 to 4 mm medial to the medial-most portion of the lateral orbital rim. If overcorrection occurs, it can be released relatively simply.     

The muscle-suspension lower blepharoplasty.

The muscle-suspension (or muscle sling) lower blepharoplasty is a technique that can be used to some extent for all lower lids in which tightening and smoothing is desired. It seems to provide an extra degree of support by counteracting the natural tendency of gravity to produce scleral show or ectropion when the lid skin is tightened. It consists of anchoring a sling of orbicularis muscle to the periosteum of the lateral orbital rim, with an upward and lateral pull--while the skin is pulled in a more medial or upward direction.

Improving periorbital appearance in the "morphologically prone"

Patients with prominent eyes are predisposed to lower lid descent and rounding of the palpebral fissure. This deformity may be exaggerated and symptomatic after conventional lower blepharoplasty. Normalization of the periorbital appearance in "morphologically prone" patients involves three basic maneuvers. Augmenting the projection of the infraorbital rim with an alloplastic implant effectively changes the skeletal morphology, thereby providing support for the lower lid and midface soft tissues. Subperiosteal freeing and elevation of the lower lid and midface recruits soft tissues and allows lower lid repositioning. Lateral canthopexy restores palpebral fissure shape and provides additional lid support. The technique can be adapted for morphologically prone patients who are first seeking improvement in their periorbital appearance or for those whose lid malposition and round eye appearance have been exaggerated by previous lower blepharoplasty. This surgery has been effective treatment for 13 morphologically prone patients operated on over a 4-year period.     

The role of the septal reset in creating a youthful eyelid-cheek complex in facial rejuvenation

Resetting of the septum orbitale over the orbital rim, or "septal reset," is the latest step in achieving periorbital rejuvenation in composite rhytidectomy. The first significant step was the addition of orbicularis repositioning to conventional lateral vector deep plane rhytidectomy, followed by orbital fat preservation using the arcus marginalis release and fat transposition over the orbital rim. Those early procedures have been further refined to include the zygomaticus muscles with the orbicularis oculi in the composite flap, or zygorbicular cheek flap, and a septal reset. The septum orbitale reset has distinct advantages over transposition of orbital fat alone, as it creates a firmer undersurface for the lower eyelid. This maneuver will create a truly youthful lower eyelid-cheek complex, as the normal concave aging skeletonization of the periorbit is transformed to a convex contour of youth. The effectiveness of this operation can be demonstrated in most variations of human anatomy, whether congenital or iatrogenic, allowing the plastic surgeon to utilize the septal reset in virtually every patient undergoing and desiring a harmonious facial rejuvenation.     

Surgical anatomy of the ligamentous attachments in the temple and periorbital regions

This study documents the anatomy of the deep attachments of the superficial fasciae within the temporal and periorbital regions. A highly organized and consistent three-dimensional connective tissue framework supports the overlying skin and soft tissues in these areas. The regional nerves and vessels display constant and predictable relationships with both the fascial planes and their ligamentous attachments. Knowledge of these relationships allows the surgeon to use the tissue planes and soft-tissue ligaments as intraoperative landmarks for the vital neurovascular structures. This results in improved efficiency and safety for aesthetic procedures in these regions.     

New aspects of the topographical anatomy of the mammary gland regarding its neurovascular supply along a regular ligamentous suspension

The exact location of the main nerves and vessels to the breast and the nipple-areola complex has always been obscure. We found that the course of the rich neurovascular supply to the nipple runs along a regularly-located, suspensory apparatus and can therefore be predicted exactly. It consists of a horizontal fibrous septum originating at the pectoral fascia along the 5th rib, merging into vertical ligaments along the sternum medially and along the lateral border of pectoralis minor laterally. Cranially, and in an anterior direction, the vertical ligaments are connected by the superficial fascia. In the current anatomical study, we seek to demonstrate the vascular supply provided by these structures more impressively. For this purpose we dissected the ligamentous suspension after intraarterial injection with colored latex in both breasts of 10 female cadavers. The large vessels, guided by this circle of fibrous attachments could then be seen clearly. In a further 4 female cadavers, a similar procedure was performed after intraarterial injection of surgical ink. This stained the vascular layers even more intensely. This topographical knowledge has clinical relevance. The rich and constant neurovascular supply to the nipple areola complex may be maintained in a new breast-reduction technique, which allows safe postoperative viability and sensibility of the nipple. The clinical results act as a striking evidence of our anatomical findings. Further procedures taking advantage of the easy determination and access to the neurovascular supply may be seen in future.     

Anatomicohistologic study of the retaining ligaments of the face and use in face lift: retaining ligament correction and SMAS plication

Plastic surgeons have sought to improve nasolabial folds, jowls, jaw lines, and cervical contour with face-lifting procedures that are abundant in the literature. The retaining ligaments of the face support facial soft tissue in normal anatomic position, resisting gravitational change. As this ligamentous system attenuates, facial fat descends into the plane between the superficial and deep facial fascia, and the stigmata of facial age develop. In this study, surgical correction of the retaining ligaments and plication of the superficial musculoaponeurotic system (SMAS) to reposition the structures that have descended with gravitation are discussed. The anatomy of the facial retaining ligaments was studied in 22 half-faces of 11 fresh cadavers, and the localization, extension, and width of the ligaments were examined macroscopically and histologically. Surgical correction of the retaining ligaments and plication of the SMAS have been accomplished in 27 face-lift patients with this anatomicohistologic study taken into consideration. There was hematoma in one patient at the cheek region and a permanent dimple caused by postoperative edema in two patients, with a localization of one zygomatic and two parotidomasseteric ligaments. In one patient, hypesthesia in the mandibular nerve region was seen, which remitted at 14 weeks. There were no other complications, and with a follow-up of 24 months, excellent aesthetic results and a high level of patient satisfaction were encountered.     

A critical analysis of the current surgical concepts for lower blepharoplasty

This article discusses the new trends in lower blepharoplasty. Many different techniques have been described for the treatment of lower lid deformities, some favoring the transconjunctival approach that avoids touching the orbicularis oculi muscle, others recommending the muscle cutaneous flap. In some cases, maintenance of the fat is indicated, whereas in others its removal is recommended. To clarify such divergences, the author performed 100 blepharoplasties. The transconjunctival approach was performed with or without skin removal and with or without canthopexy, and the muscle cutaneous flap method was performed with or without fat removal and with or without canthopexy. The patients were followed up and observed for 6 months. The preoperative, intraoperative, and postoperative periods were analyzed. The patient, the surgeon, and a third person evaluated the results. Preoperative and postoperative photographs illustrate this article.     

Surgical anatomy and blood supply of the fascial layers of the temporal region

In 15 fresh cadavers (30 sides), we studied the two layers of fascia in the temporal region, with particular regard to their blood supply and to their usefulness--together or separately--as microvascular free-tissue autografts. The superficial temporal fascia (temporoparietal fascia, epicranial aponeurosis) lies immediately deep to the hair follicles. It is part of the subcutaneous musculoaponeurotic system and is continuous in all directions with other structures belonging to that layer--including the galea above and the SMAS layer of the face below. The deep temporal fascia (temporalis fascia, investing fascia of temporalis) is separated from the superficial fascia by an avascular plane of loose areolar tissue. It completely invests the superficial aspect of the temporalis muscle down to (but not beyond) the zygomatic arch. It is firmly attached to periosteum all around the margin of the muscles. Below it is attached to the upper border of the zygomatic arch. We found the deep temporal fascia to be supplied solely by the middle temporal artery, a constant branch of the superficial temporal. The middle temporal artery arises 1 to 3 cm below the upper border of the zygomatic arch, runs always superficial to the arch, and enters the deep temporal fascia immediately above that layer's attachment to the zygomatic arch. If the middle temporal vessels are protected, the two layers of temporal fascia can be raised together as a fully vascularized tissue island. This island can be fashioned as a bilobed or a double-layered flap, depending on the manner of dissection. The potential surgical usefulness of these findings is discussed.     

A new technique for the treatment of palpebral bags

A new technique for the treatment of palpebral bags is presented. The technique consists of returning fat to the orbital cavity and retaining it by means of a continuous suture (with nonabsorbable filament) of the capsulopalpebral fascia to the periosteum of the lower orbital rim. The anatomic basis for the technique, after examination of the relevant literature and dissection on fresh cadavers, is analyzed. The procedure followed and results obtained are described in detail. Evaluation of the results suggests to the authors that this might be the method to be applied in the majority of patients.
