Witch's chin is an unpleasant aesthetic defect characterized by ptosis of premental tissue and a deep submental fold, which may be exaggerated by hyperprojection of the mandible. These three elements determine the different degrees of deformity; therefore, the ideal treatment should be directed to one, two, or all three of them. Despite unanimity on the surgical approach of the defect, a large variety of techniques have been proposed by various authors. The need to use a technique suitable for different clinical pictures, characterized by a progressive surgical aggression, as usually performed in this practice, has led to standardize a technique to correct witch's chin, by means of three progressive steps, depending on the degree of deformity. The advantage of this procedure is that once a good result has been achieved, the subsequent steps may be omitted. The technique has been successfully performed in five patients, and the mean follow-up is 12 months. Figures from two representative cases are presented.  相似文献

Improving aesthetic outcomes after alloplastic chin augmentation   总被引:4,自引:0,他引:4  
Yaremchuk MJ 《Plastic and reconstructive surgery》2003,112(5):1422-32; discussion 1433-4
A novel approach to increase chin projection with alloplastic material is presented. Key aspects of the technique include the consideration of anthropometric normal values in preoperative assessment and planning, a submental approach with wide subperiosteal exposure of the area to be augmented, the use of two-piece porous polyethylene implants for augmentation, and screw fixation of the implant to the mandible. Screw fixation improves the predictability and precision of reconstruction by preventing implant displacement, by obliterating gaps between the implant and the facial skeleton, and by facilitating final implant contouring. In a series of 46 patients (24 primary and 22 secondary) operated on over a 6-year period, this approach allowed anatomically correct, stable chin contours to be created. Iatrogenic problems with macrogenia, mentalis dysfunction, and soft-tissue distortion resulting from implant migration and capsular contracture have been avoided. There have been no infections. Two patients who had had multiple previous chin operations requested revisional surgery to refine contour.  相似文献

Although ptosis of the tip of the chin is common and can be seen in persons of any age, it is frequently seen in older patients seeking facial rejuvenation. A variety of techniques have been described to correct ptosis of the chin. The authors describe a minimally invasive method that can be used correct chin ptosis. This technique uses a small intraoral incision to place a U-shaped Prolene suture that gathers the soft tissue of the chin and elevates it above the lower border of the mandibular symphysis. A retrospective review of 314 cases performed in conjunction with face lifts between January of 1994 and January of 2000 was performed to evaluate this technique. There were no significant complications, and long-term results have been very satisfactory and lasting.  相似文献

This article is a logical extension of previous articles written on the topic of aesthetic chin surgery. In it, the authors expand on previously published surgical techniques and provide specific updates to increase success in some unusual situations. They review the indications for and uses of reduced-height implants, discuss the validity of centralized chin incisions in both reconstruction and revisions, show the diversity of mentalis muscle anatomy and chin pad variations, reveal the importance of the lip-to-labiomental crease inclination in cases of macrogenia, note a key update on reefing the mentalis muscle to a higher position for permanent sulcus position, discuss the issues of lower lip position and lower incisor show, and expound on the horizontal smile/chin ptosis phenomenon.  相似文献

Profile enhancement most frequently involves mentoplasty. For this purpose, the author performs conchal grafts to the chin. A total of 28 women aged 15 to 76 years (mean age, 38.11 +/- 15.11 years) requested mentoplasty by itself or combined with rhinoplasty, rhytidoplasty, or submental lipoplasty. The conchal cartilage was harvested subperichondrally through a posterior 3-cm incision. The specimen measured 3 x 1 cm, which was sufficient to project the chin 2 to 3 mm. For 4 to 5 mm of projection, both cartilages were used. The graft was positioned under the periosteum and held with two 5-0 nylon sutures. In these cases, the conchal cartilage graft was a suitable option for chin augmentations up to 5 mm.  相似文献

Excess skin of the upper lids is often accompanied by lateral overlap of skin with crow's feet because of the absence of fixation to the tarsal plate, giving the eye a sad, heavy look that often disturbs the lateral visual field. The accepted crescent-shaped blepharoplasty is somewhat convex, which is widest at the center of the lid with or without a lateral extension. However, in patients who have normal brow position or minimal eyebrow ptosis and whose main concern is the excess upper eyelid skin and lateral hooding, such a crescent excision may not suffice. A scalpel-shaped excision that is widest laterally and that tapers to a point medially will extirpate the maximal skin where it is most needed and overcome the skin excess in the lateral aspect of the upper lid. Between 1990 and 2002, 301 white patients (275 women and 26 men) between the ages of 33 and 79 years were operated on using the extended scalpel-shaped upper blepharoplasty technique. The follow-up period was more than 1 year. The lower margin of the incision is along the supratarsal crease, about 10 mm above the ciliary line. It begins medially about 1 cm above and lateral to the medial canthus. Above the lateral canthus, the skin marking is gently curved upward and outward, often within a natural skin crease or crow's feet to reach a little below and slightly beyond the lateral extremity of the eyebrow. The upper border of the incision joins the two extremities of the skin outline in a gentle convex curve. The general outline of the incision takes on the shape of a number 20 scalpel blade in which the maximal width is located laterally. Following excision of the excess skin and removal of protuberant fat pads if needed, suturing is executed from lateral to medial. The final suture line is in the form of an oblique flattened lazy S. Following the removal of the stitches on the fifth postoperative day, no wound dehiscence was noticed at the lateral scar zone. In the older individuals, due to the lax skin, the scar becomes scarcely noticeable with time and often falls within a pre-existent crow's feet crease. Elimination of some of the crow's feet was also demonstrated. In patients with visual field impairment, significant functional and visual improvement was achieved. Most patients mentioned a pleasing postoperative open "Oriental" look of the eyes. The extended scalpel-shaped upper blepharoplasty adequately deals with the hooding of the skin laterally. This technique overcomes the excess of skin in both vertical and horizontal directions, since in suturing the lateral part of the skin defect in an oblique plane, slack skin is taken up transversely, and the technique provides some indirect upward support to the lateral eyebrow. In the absence of crow's feet in the younger person, this technique is not recommended because the lateral part of this suture line is visible, especially if the scar widens.  相似文献

I didactically compared the breast as a glandular cone with an envelope of skin and subcutaneous tissue. The aesthetic alterations of the breast are classified in four groups related to form, to volume, to grams, and to ptosis in centimeters. An imaginary plane that passes by the mammary sulcus (plane A) will determine the area of the breast that is ptotic. The projection of this plane in the anterior part of the breast is called point A. The distance between point A and the nipple will give in centimeters the amount of ptosis. I use this distance to draw geometrically in the breast the amount of excess of skin to be removed to correct the ptosis. In group I, the volume is normal and part of the mammary gland is under plane A. In this type of breast, the skin is resected, and since there is no excess of breast tissue, the breast that is under plane A is used as an inferior pedicle flap to give a better volume to the new breast. In group II, the base of the breast is large, the height is normal, and the volume is increased by the enlargement of the base. In this type of breast, the excess of breast under plane A and a wedge under the nipple are resected to reach the normal volume at the end of the surgery. In group III, the base is normal and the volume of the breast is increased by the height. For treatment, I resect the excess of breast under plane A as well as a segment at the base to reduce its height. In group IV, the volume of the breast is increased by the size of the base and the height of the cone, and I treat by resection of the excess of tissue under the ptotic area, a wedge under the areola, and a transversal segment in the base to reduce all the dimensions. In the final result of this technique in the majority of patients I will obtain a short scar. This technique was used in 1083 patients from January of 1979 to May of 1988.  相似文献

Fascial anchoring technique in medial thigh lifts   总被引:4,自引:0,他引:4  
The medical thigh lift has not gained widespread acceptance since its introduction 20 years ago because of problems such as inferior scar migration, labial separation, and early recurrence of ptosis. Anchoring of the inferior skin flap to the tough, inelastic deep layer of the superficial perineal fascia has reduced such complications. Originally described by Colles in 1811, this fascial layer helps define the perineal-thigh crease. Eighteen patients having medial thigh lifts in combination with liposuction were followed for 6 to 24 months. The technique involves initial liposuction followed by resection of a crescent of redundant skin and fat at the superior medial thigh. The inferior skin flap is suspended from Colles' fascia of the perineum with subdermal PDS sutures. No undermining or deepithelialization of flaps is performed. Complications are few, and patient satisfaction is high.  相似文献

We describe a technique to eliminate the vertical portion of the inverted-T incision in patients who have combined enlargement of the breasts and moderate to severe ptosis. Initial preoperative markings are made, placing the new nipple site at the level of the transposed inframammary crease. The nipple-areola complex is then retained on a vascularized pedicle, with major reduction of the breast tissue being done in the medial and lateral quadrants. The nipple and breast tissue are then tucked underneath the superior skin segment and placed in this new position as one would do with the umbilicus in an abdominoplasty. Excess vertical skin is removed, and horizontal excess is collected at the midline as a small dog-ear. We have found that this dog-ear reduces markedly with time, rounding out the inferior portion of the breasts. The remaining small amount of excess skin can then be removed under local anesthetic at a later date. We have performed this procedure on 20 patients, with follow-up from 6 to 24 months.  相似文献

Submandibular gland resection for aesthetic reasons has been hotly debated. Detractors maintain that the procedure is dangerous because it puts too many important structures at risk, notably motor nerves. The present study was undertaken to elucidate the neurovascular and soft-tissue anatomy of the digastric triangle via cadaver dissections so that a surgical approach to achieve safe aesthetic submandibular resection could be performed. Fifteen digastric triangles dissections were performed in fixed and fresh cadaver specimens. The dissection focus was to understand the submandibular neurovascular relationships, capsule as well as fascial layers, and measurements to known structures. The marginal mandibular nerve is located external to the submandibular capsule, approximately 3.7 cm cephalad to the inferior margin of the gland. The hypoglossal nerve is posterior to the digastric sling in a position that is protected deep within the visceral layer of the neck. The lingual nerve is located underneath the mandibular border, crossing anterior to the submandibular duct. The vascular supply is variant, but with an average of one and a half vessels entering medially to the superficial lobe of the gland, one intermediate vessel entering medially to supply the superficial and deep lobes, and one deep perforator that runs from the central portion of the deep lobe to the superficial lobe. Appreciation of this anatomy is critical in the submental approach for partial resection. Although it can be technically challenging, the anatomy is straightforward and partial submandibular gland resection can be executed via a consistent, safe approach to optimize facial rejuvenation in certain patients.  相似文献

Liposuction abdominoplasty: an evolving concept   总被引:5,自引:0,他引:5  
Brauman D 《Plastic and reconstructive surgery》2003,112(1):288-98; discussion 299-301
Liposuction abdominoplasty-liposuction of abdominal subcutaneous tissue deep and superficial to Scarpa's fascia, with excision of excess abdominal skin and, when indicated, plication of the anterior rectus sheath without undermining-is an effective, low-risk approach to minimizing abdominal flap undermining. The technique allows aggressive thinning and "sculpting" of full-thickness abdominal subcutaneous tissue and achieves a natural (not featureless) abdominal contour. It minimizes the creation of "dead space," which often leads to postoperative complications, as well as preserves sensory nerve and blood supply to the abdominal skin. The operation may be performed with the patient under local anesthesia, which probably diminishes the risk for deep vein thrombosis. Moreover, additional procedures can be conducted safely and the postoperative course is short, uneventful, and without restrictions; patients return to normal activity within a week or so. New evaluation criteria for abdominoplasty are discussed in this article, the most important of which is the assessment of intraabdominal fat content and its impact on surgical outcome and the decision to perform anterior rectus sheath plication. The concept of a sliding, mobile, sensate abdominal flap, created by liposuction and sustained by multiple neurovascular mesenteries, is also offered.  相似文献

Chin disfigurement following removal of alloplastic chin implants   总被引:2,自引:0,他引:2  
Insertion and subsequent removal of alloplastic chin implants is not an innocuous procedure, as commonly believed. Ten women, aged 23 to 62 years of age (mean 45 years) are reported in whom severe soft-tissue deformities were observed 6 months to 6 years (mean 32 months) after removal of their implants. Resulting deformities consisted of chin ptosis and bizarre soft-tissue pogonial bunching and dimpling in repose or on animation in 9 of the 10 patients (90 percent). Asymmetrical motion of the lower lip was noted by 5 of the 10 patients. Two patients complained of pain and tenderness over the soft-tissue pogonion. The "bizarre" soft-tissue chin deformities, once established, are virtually uncorrectable. Presently, we recommend serious consideration be given to performing an immediate osseous genioplasty in patients requiring removal of alloplastic chin implants to prevent the evolution of such abnormalities.  相似文献

The soft-tissue chin may become ptotic following surgery in this area. The mentalis muscles which are responsible for proper central lip motion and chin point position may be affected. The mentalis muscle origin may require resuspension at a proper level. This reattachment may be performed by means of an intraoral approach. Non-absorbable sutures are used to hold the soft-tissue chin upward. The exact method involves placing drill holes through the alveolar bone, into which sutures are passed. These sutures are then placed through the lower mentalis muscles and tightened. Chin and lip position may be corrected in certain cases. Ancillary procedures are required to correct vestibular scarring and submental scars.  相似文献

In 1922, Thorek described standard free-nipple reduction mammaplasty for gigantomastia. This technique provided a simple and effective way to perform reduction mammaplasty. However, the technique is frequently criticized for producing a breast and nipple with poor projection. Even with the standard modification of the original technique, the resultant breast and nipple may be wide and flat, with unpredictable nipple-areola pigmentation. To create a breast mound and nipple with projection and even pigmentation, the free-nipple-graft breast reduction technique is presented. The Wise pattern skin reduction markings and the superiorly based parenchymal reduction technique are used. After the nipple-areola complex is removed, as a free graft, the inferior pole of the breast is then amputated along the Wise pattern skin markings, leaving lateral and medial pillars of breast tissue, with the apex of the resection corresponding to the new nipple location. The lateral and medial pillars of the superiorly based breast mound are then sutured together. Key interrupted sutures are placed, beginning at the most inferior and posterior point of the pillars, while recruiting tissue centrally to increase the projection. The intersecting point of the inverted T, at 7 cm from the new nipple position, is then sutured to the fasciae of the pectoralis major muscle. If more central projection is desired, the vertical limb design can be lengthened. The tissue inferior to the 7-cm mark is de-epithelialized and tucked under the central breast, if needed, contributing further to the final breast parenchyma projection. The skin of the vertical limb of the Wise pattern is then closed with a dog-ear at the apex to further contribute to nipple projection. The nipple is replaced as a free, thick, split-thickness skin graft. The breast is temporarily closed, and the medial and lateral breast tissue excess is liposuctioned to create a more conical breast. Excessive medial and lateral skin is then resected, keeping the inframammary crease incision under the breast mound. Twenty-five patients underwent free-nipple-graft reduction mammaplasty using this technique between 1992 and 2000. An average of 1600 g of breast tissue per breast was removed. The average follow-up period was 36 months. Patient satisfaction has been very high.  相似文献

Supratip deformity, a hallmark of a poorly executed rhinoplasty or an inauspicious healing, continues to plague the novice often and the experts on occasion. A clinical and histopathologic study was conducted to search for the surgical causes of this deformity and its histologic presentation. An organized, logical management program was then developed. Clinically, supratip fullness was observed in both primary (26 of 298 patients; 9 percent) and secondary (40 of 112 patients; 36 percent) rhinoplasty candidates. In primary patients, the deformity was the result of inadequate tip projection (pseudodeformity), an overprojected caudal dorsum, a combination of both, or cephalically oriented lower lateral cartilages. In secondary patients, the deformity was caused by an underresected or overresected caudal dorsum, overresected midvault, underprojected tip (pseudodeformity), or a combination of some of these factors. The histopathologic evaluation demonstrated significant fibrosis in the supratip soft tissue of 14 of 16 patients undergoing secondary rhinoplasty without the injection of triamcinolone acetonide and in only 13 of 23 patients who underwent primary rhinoplasty (p<0.05). A supratip deformity can be eschewed by proper resection of the caudal dorsum, avoidance of dead space, restoration of adequate projection to the nasal tip, and an approximation of the supratip subcutaneous tissue to the underlying cartilage using a supratip suture, hence eliminating the dead space. If the problem is noted shortly after surgery, in the presence of collapsible consistency of the supratip tissue and adequate projection, the treatment is taping the supratip tissue as often as it is practical. If no favorable response is elicited in 6 to 8 weeks, thejudicious injection of a small amount of triamcinolone acetonide (0.2 to 0.4 cc of 20 mg/cc) in the deep subcutaneous tissue (not in the dermis) is done. The injection is repeated in 4-week intervals until the desired effect is achieved. If supratip fullness is the consequence of inadequate cartilage resection or inadequate tip projection, surgical correction is needed. The recalcitrant soft-tissue excess in the supratip area is resected, and the subcutaneous soft tissue is approximated to the underlying cartilage. If the dorsum was previously overresected, a cartilage graft to the caudal dorsum or midvault will create an optimal dorsal frame and reduce the potential for a recurrent supratip deformity.  相似文献

Reduction mammaplasty with the "owl" incision and no undermining   总被引:3,自引:0,他引:3  
Ramirez OM 《Plastic and reconstructive surgery》2002,109(2):512-22; discussion 523-4
Reduction mammaplasty has traditionally been done using the Wise pattern of incision. Because of the box-like effect in breast shape, the lack of projection, and the long scars associated with the inverted T incision, two techniques have emerged as alternatives: the vertical reduction of Lassus/Lejour and the "round block" periareolar technique popularized by Benelli. Each of these techniques has its pros and cons.The "owl" incision combines the features of the large periareolar reduction (Benelli's) and the vertical reduction (Lassus/Lejour); the horizontal inframammary scar is either made very short or completely eliminated. Volume reduction is done through a heart-shaped parenchymal resection, leaving the nipple-areolar complex over a supero-central pedicle. Maintenance of the central parenchyma behind the nipple-areolar complex and mobilization of the vertical pillars toward the center of the breast give excellent projection and diminish the lateral fullness. Enlargement of the periareolar skin resection diminishes the length and pleating of the vertical scar; conversely, inclusion of the vertical component to the periareolar technique eliminates the pleating effect of the periareolar incision. The short horizontal excision eliminates any resultant "dog ears" in the new inframammary fold. Thus, the discrepancy in the length of scars is better distributed. There is no skin or parenchymal undermining, so drains are not needed. Excellent results are obtained immediately on the operating table, and large volumes of glandular resection and correction of severe ptosis can be accomplished without compromising vascularity of either the nipple-areolar complex or the skin flaps.Ninety-four patients in a 7-year period were operated upon using this technique. Seventy-two had bilateral reductions up to 1900 gm per breast, 12 had unilateral reduction for symmetry following breast reconstruction, and 10 were patients with severe ptosis. Complications were rare and of a minor nature. No conversion to free grafts was done, even in the larger resections. One case required minor revision under local anesthesia, one case required bilateral re-reduction, and another case required unilateral re-reduction for continued growth of breast tissue. Almost 90 percent of the patients underwent procedures as outpatients.The owl-type incision and the supero-central pedicle flap are elements of a reduction mammaplasty technique that provides excellent projection and shape with minimal visible scars. It takes advantage of the positive features of the periareolar and vertical reduction techniques and minimizes their negative features. The new design of parenchymal resection improves the vascularity of the residual flaps. Additionally, it may better preserve the sensation to the nipple-areolar complex and lactation is not compromised.  相似文献

Dual-pedicle dermoparenchymal mastopexy   总被引:1,自引:0,他引:1  
Mastopexy for treatment of breast ptosis, with or without augmentation or reduction, is often followed by recurrent ptosis. A new mastopexy technique is described which appears to offer long-term correction. After conservative resection of excess skin, the breast parenchyma is elevated from the chest wall, and redundant caudal deepithelialized breast tissue is divided into two equal (or unequal) superiorly based pedicles. These are criss-crossed (as in folding of arms), overlapped, and secured to the pectoral fascia in a position cephalad to the nipple-areolar complex. This technique, dual-pedicle dermoparenchymal mastopexy (DPM), forms a cone of the breast tissue and provides a "cradle" of support. It permits insertion of a prosthesis if needed. Based, in part, on concepts of traditional and more recently described pedicled breast reductions, it enjoys the advantage of preserving skin attachment to underlying unresected breast parenchyma. In addition, it repositions ptotically displaced breast parenchyma into a cephalad position and fixes it (the "pexy") to the chest wall. A 10-year experience is presented with representative cases to illustrate the basic mastopexy and its use with augmentation or reduction.  相似文献

Most men develop visible redundant tissue in the anterior neck with aging. Some seek surgical improvement. If the patient does not wish to have a conventional face/neck lift, anterior cervicoplasty is a good option. The procedure accomplishes tightening in the horizontal direction by excising a midline vertical ellipse of skin and subcutaneous fat. The surgeon tightens and lengthens the platysma muscles by suturing the anterior borders of the muscle to each other and by performing one or more Z-plasties in the muscle. A Z-plasty in the skin and subcutaneous tissue predictably creates a mental/cervical crease or angle with precise planning of the location of the horizontal limb. It also provides added length to the vertical skill closure. Every patient has thought that the improved contour of his neck more than offset the presence of a visible scar. In fact, no patient has indicated that his scar has been noticed by others, nor has any patient requested scar revision.  相似文献

Some modified surgical techniques are described for constructing a deep conchal cavity and pseudomeatus and obtaining high auricular projection in congenital microtia. At the primary operation, a rather small portion of the microtic vestige is utilized for the lobule by switching, sparing the skin for the concha, with no free skin graft used. For higher projection of the auricle, three-dimensional transposition of a retroinfraauricular flap together with cartilage pieces underneath is applied to the cephaloauricular sulcus. A deep conchal cavity is constructed by further removal of the soft tissue there, transplantation of a cartilage for building a high posterior wall of the concha. The external meatus is successfully imitated by transplantation of a cone-shaped composite graft taken from the cymba of the opposite ear. The retroinfraauricular flap, the reconstruction of a deep concha, and the composite graft technique were successfully used in 55, 16, and 11 ears, respectively.  相似文献

Disharmony between the skeletal support and the softtissue envelope is a common cause of aesthetic concerns regarding the lower face. A loss of volume or a genetically small mandible affects the aesthetics and function of the mouth, chin, and neck. Because of the limitations of correcting such problems with current implants made of silicone or porous polyethylene, the author developed an implant system and a method of restoring the entire volume of the mandible called the mandibular matrix implant system. This implant system is made of high-density porous polyethylene and is composed of an articulated wraparound geniomandibular implant and a wraparound gonial angle implant. A prejowl implant can be integrated in the system as an addition or as a replacement for a chin implant. This implant system has different sizes and projections, and it can be modified by carving to fit the requirements of most patients. Carving is done using an appropriate sizer. This implant system is indicated for use in patients with a congenitally small mandible, edentulous patients, and patients requesting facial enhancement. The mandibular matrix implant system is implanted either during a single procedure or simultaneously with a facial rejuvenation. The extended geniomandibular implant is introduced through an anterior oral sulcus incision or a submental incision. The mandibular angle implant is introduced through a retromolar incision. The posterior end of the chin implant overlaps the anterior end of the gonial implant, and screw fixation of each chin component helps to stabilize the entire system. Antibiotics, irrigation, and closure of the incisions are performed before any additional operative procedure. The complete system has been used in 13 patients; one additional patient had the complete system plus an overlapping additional left prejowl implant for correction of asymmetry. Complications were manageable; these included one mandibular angle implant displacement and one infection. The implant displacement required a reoperation to reset the implant. The infection was treated with irrigation and closed system suction; the implant was salvaged. The satisfaction of patients has been high, and the author can now solve aesthetic problems that in the past were considered unsolvable.  相似文献
