Distribution of submental fat in relationship to the platysma muscle.

The results of submental lipectomy often remain suboptimal, and in some cases this may be due to the presence of residual fat deep to the platysma muscle. This study was undertaken to determine the relative amounts of fat superficial and deep to the platysma muscle. A dissection of the submental region of 20 cadavers revealed a mean weight of fat lying superficial to the platysma muscle of 8.4 grams. The mean weight of fat lying deep to the platysma muscle but superficial to the mylohyoid muscle was 3.7 grams. In three cases (15%), the weight of fat deep to the platysma muscle was greater than 50% of the total fat. This is of significance with respect to those submental lipectomy procedures that normally address only the fat superficial to the platysma.

Esthetic contour analysis of the submental cervical region: a study based on ideal subjects and surgical patients.

A cephalometric analysis of the submental-cervical region was carried out by examining and comparing 16 white adults who had ideal submental-cervical esthetics with 16 adult orthognathic surgery patients who were treated by submental lipectomy or liposuction and various orthognathic surgical procedures. A normative data base of the submental-cervical region was derived from the ideal subject group. The submental-cervical morphology of the preoperative patients differed significantly from the ideal subjects. The submental-cervical angle (Sm-Ce) and the submental soft tissue thickness at C point (IBM-Sm) presented the greatest disparity between the ideal subjects (118.0 degrees, 28.0 mm) and the preoperative patients (158.3 degrees, 42.1 mm, each P < .001). After surgery, Sm-Ce and IBM-Sm decreased to 132.8 degrees (P < .001) and 28.7 mm (P < .001), respectively. By the end of 6 months postoperative, the mean values of Sm-Ce and IBM-Sm were 131.1 degrees and 28.6 mm. The submental soft tissue thickness of the patients 6 months after surgery was not statistically different from the ideal subjects (each P > .05). Orthognathic surgical procedures with concomitant submental lipectomy or liposuction had a significant effect on the contour of the submental and cervical soft tissues.

Lipodystrophy and its treatment.

Lipodystrophy, almost exclusively seen in female patients, causes psychological problems at an early age. In later life, additional complaints are heavy painful legs, edema, and varicose veins. Nearly all patients suffer from alimentary adiposity. Dermolipectomies in general are not advisable because of the resulting large scars and the risk of damaging the lymphatic system. Subcutaneous lipectomy according to the Illouz method can provide good results. Weight loss is a good alternative to liposuction of the upper legs. After sufficient weight loss, only additional liposuction of the trochanteric area and the medial side of the knee is needed. No unpleasant scarring of the leg results. Unfortunately, older patients often require a skin reduction. The results of surgery in the lower legs were, except in 2 patients, good to excellent. The results in the upper legs were disappointing because 9 of 11 patients gained weight again after surgery. Considering this, the preferable treatment now is liposuction of the lower legs, medial side of the knee, and the trochanteric area. Only in cases of ptotic skin on the medial side of the upper legs is skin reduction without lipectomy indicated. Lipodystrophy suggests a disappearance of the subcutaneous fat. When this occurs in the upper part of the body, it is called progressive lipodystrophy. Lipodystrophy is known as an abnormality of the lower half of the female body, swollen by deposition of subcutaneous fat and determined by heredity. It occurs more frequently in the lower social classes and is often accompanied by an alimentary obesity which is a psychological reaction to the disturbed body image.(ABSTRACT TRUNCATED AT 250 WORDS)

Lipoplasty in the bulimic patient.

Recent cases in our Eating Disorders Clinic suggest that patients diagnosed with bulimia nervosa seeking surgical fat removal may be exhibiting a variant of the purging behavior seen in bulimic patients. These same patients exhibit historical or concurrent abuse of laxatives and/or diuretics or self-induced vomiting in a pathologic attempt to obtain or maintain an idealized body image. This paper presents two case studies that illustrate the bulimic patient's compulsive quest for lipectomy with unrealistic expectations that surgical alteration of the body will be an emotional and physical panacea. Plastic surgeons must be cautioned regarding this potential manifestation of bulimia nervosa and the dangers inherent in colluding with the patient in a pathologic request for surgery. It is important for plastic surgeons to recognize appropriate use of lipectomy as an alternative to traditional purging behavior in the bulimic patient.

Simultaneous osseous genioplasty and meloplasty.

A review was done of the records of 50 patients who had osseous genioplasty performed at the same sitting as face lifting and, in many cases, submental lipectomy over a 20-year period by the senior author. The types of genioplasties were sliding advancement (40), lengthening with interpositional bone graft (7), and reduction (3). In 9 patients, chin implants were removed, generally because of inadequate chin projection or implant erosion. Three patients were operated on under local anesthesia, the remainder under general anesthesia. Associated procedures, done in 46 patients, included rhinoplasty, forehead lifting, blepharoplasty, lateral canthopexy, excision of buccal fat pads, reduction mammaplasty, and abdominoplasty. In 4 patients, associated maxillofacial procedures were performed, including Le Fort I and III osteotomies, two-jaw surgery, mandibular advancement with sagittal splitting, and orbital expansion. The perceived advantages of osseous genioplasty were greater versatility in dealing with problems in other than the sagittal plane, the possibility of greater chin projection, and a tightening of the submental musculature. Complications occurred in 10 patients. These included two hematomas requiring aspiration in the office, a prolapsed submandibular gland requiring later excision, a transient weakness of the marginal mandibular nerve, a transient numbness of the lower lip on one side, four revisions of scars resulting from the face lifting, and one localized wound infection in the parasymphyseal area that resolved with oral antibiotics. The most common complaint, which came from 8 female patients at some time from 1 month to 3 years postoperatively, was that the chin was "too strong." In 6 of these patients, most of whom were operated on early in the series, some of the chin projection was reduced by burring. Osseous genioplasty can be performed safely along with face lifting and submental lipectomy. The degree of advancement necessary in aesthetic surgical patients is generally less than that required in reconstructive patients. Patient satisfaction is great unless the chin is overly advanced.

The "triple technique" for treating stable Graves' ophthalmopathy.

Graves' ophthalmopathy may range from mild eyelid retraction to a devastating process that involves the entire orbit and culminates in gross ocular congestion, massive proptosis, and even blindness. Whether the ophthalmopathy is mild or severe, patients are managed on an individual basis according to the predominant clinical findings, which may include congestion, myopathy, lid retraction, proptosis, and optic neuropathy. The process usually becomes quiescent after 6 months to 3 years; however, the changes caused by fibrosis (lid retraction and ocular muscle enlargement) are permanent. The cornerstone of surgical treatment for severe cases is bony orbital decompression; however, in our experience, mild to moderate Graves' ophthalmopathy is better treated by combining eyelid surgery and orbital lipectomy. Our approach consists of a conservative orbital lipectomy, the lengthening of the levator-Müller complex by means of marginal myotomies, and a limited lateral tarsal apposition. These three different surgical steps, which have been described previously as isolated procedures, are undertaken on both eyes at the same time and modulated according to the deformity of the patient. The operation can be performed under local anesthesia with sedation, thus allowing intraoperative monitoring of the correction; the patient can be discharged after a few hours. The results in 32 operated eyes of 16 patients have been a marked aesthetic and functional improvement, with no complications after 6 to 18 months of follow-up. The relative simplicity and very low morbidity of this procedure, as well as its reliability, make it ideal in patients with mild to moderate aesthetic and functional impairment who are looking for a substantial improvement but are unwilling to undergo a relatively major procedure such as a transosseous decompression, which, in our opinion, is the operation of choice only when the patient presents with optic neuropathy or major proptosis.

Maximizing the use of the abdominoplasty incision.

Candidates for abdominoplasty often request multiple procedures at the time of consultation. Some of these patients have the potential opportunity to have ancillary procedures performed through the abdominoplasty incision, such as breast augmentation or suction-assisted lipectomy. Access via the abdominoplasty incision can also limit the need for distant donor sites, for instance, when autologous fillers or rib graft are necessary. The techniques described are straightforward and are based on standard principles that should be considered when ancillary procedures are performed in conjunction with abdominal contouring procedures. In a review of 70 consecutive patients undergoing abdominoplasty, 91 ancillary procedures were performed in conjunction with the abdominoplasty. Of the total number of patients undergoing abdominoplasty, 29 patients underwent 30 procedures facilitated through their abdominoplasty incision, including 23 suction-assisted lipectomies of the flanks, six breast augmentations, and one rib cartilage harvesting for rhinoplasty. A review of the author's experience and discussion for potential options afforded by this exposure are presented.

Anesthesia with sevoflurane in bariatric surgery.

BACKGROUND: Sevoflurane is a good halogen agent for bariatric surgery anesthesia because of its physical and chemical characteristics and its repartition coefficient (blood/gas = 0.65). METHOD: From November 1997 to April 1998, 98 bariatric surgery procedures with sevoflurane anesthesia were done: 17 lipectomies, 71 vertical gastroplasties, and 10 biliopancreatic diversions in 71 women and 27 men, average age 30.3+/-8.3 years, with body mass index 43.9+/-5.7. The average operating time was 50+/-15 minutes for vertical gastroplasty, 160+/-20 minutes for biliopancreatic diversion, and 80+/-12 minutes for lipectomy. The technique of anesthesia was as follows: preanesthesia with atropine sulfate 0.01 mg/kg (dosage refers to ideal weight), ranitidine 50 mg, fentanyl 0.1 mg, ketorolac 60 mg; induction with propofol 0.5-1 mg/kg, succinylcholine 1 mg/kg; orotracheal intubation; maintenance with O2-N2O 50%, sevoflurane 1% to 1.5%, actracurium 0.5 mg/kg (dosage refers to ideal weight); awakening and decurarization with atropine sulfate 1 mg and prostigmine 2 mg. RESULTS: This method permitted correct control of the anesthesia, a quick awakening with a low incidence of nausea and vomiting, a prompt regain of physical and psychological functioning, an early discharge from the hospital, and a larger turnover of patients with lower costs. CONCLUSION: Sevoflurane balanced anesthesia seems to be the best anesthesiologic method for bariatric surgery.

Lipid metabolism of monosodium glutamate obese rats after partial removal of adipose tissue.

We analyzed the effects of partial fat pad removal on retroperitoneal and epididymal fat depots and carcass metabolism of control (C) and MSG-obese (M) rats. Three-month-old C and M male Wistar rats were submitted to either partial surgical excision of epididymal and retroperitoneal fat tissue (lipectomy, L) or sham surgery (S) and studied after 7 or 30 days. Retroperitoneal and epididymal tissue re-growth after lipectomy was not observed, as indicated by the low pads weight of the L groups. The lipolysis rate was stimulated in LC7 and LM7, probably due to surgical stress and low insulin levels. In LM7, but not in LC7, in vivo lipogenesis rate increased in retroperitoneal and epididymal fat tissue, as did the diet-derived lipid accumulation in epididymal fat tissue. Although these local increases were no longer present in LM30, this group showed a large increase in the percentage of small area adipocytes in both pads as well as increased carcass lipogenesis rate. The present data showed that the partial removal of fat depots affected the metabolism of control and MSG-obese rats differently. In the obese animals only, it stimulated both local and carcass lipogenesis rate as well as adipocyte differentiation, i.e. responses likely to favor excised tissue re-growth and/or compensatory growth of non-excised depots.

The tumescent technique: the effect of high tissue pressure and dilute epinephrine on absorption of lidocaine.

Injection of lidocaine into the subcutaneous tissues by the tumescent technique results in a delayed absorption of the local anesthetic and has allowed clinicians to exceed the maximum recommended dose of lidocaine without reported complications. However, little knowledge exists about the mechanisms that permit such high doses of lidocaine to be used safely with this technique. The presence of low concentration epinephrine and the increased tissue pressure resulting from the tumescent injection have both been implicated as important factors, but neither has been studied in patients whose results were not altered by the variability of the suction procedure. The purpose of this work was to determine the effect of tissue pressure during tumescent injection and presence of low concentration epinephrine on the absorption of lidocaine from subcutaneous tissues in human volunteers. Twenty healthy female human volunteers were randomized into four study groups. After body fat measurements, all subjects received an injection of 7 mg/kg of lidocaine into the subcutaneous tissues of both lateral thighs. The injected solution consisted of 0.1% lidocaine and 12.5 meq/liter sodium bicarbonate in normal saline with or without 1:1,000,000 epinephrine. Tissue pressure was recorded during injection using a specially designed double-barreled needle. The time required for injection was also recorded. Subjects in group 1 received lidocaine with epinephrine injected by a high-pressure technique. Group 2 subjects received lidocaine with epinephrine injected by a low-pressure technique. Group 3 subjects received lidocaine without epinephrine injected under high pressure. Group 4 subjects received lidocaine without epinephrine injected under low pressure. Following injection, sequential blood samples were drawn over a 14-hour period, and plasma lidocaine concentrations were determined by gas chromatography. No suction lipectomy was performed. Maximum tissue pressure during injection was 339 +/- 63 mmHg and 27 +/- 9 mmHg using high- and low-pressure techniques, respectively. Addition of 1:1,000,000 epinephrine, regardless of the pressure of injected fluid, significantly delayed the time to peak plasma concentration by over 7 hours. There was no significant difference in the peak plasma concentration of lidocaine among the four groups. Peak plasma concentrations greater than 1 mcg/ml were seen in 11 subjects. Epinephrine (1:1,000,000) significantly delays the absorption of lidocaine administered by the tumescent technique. High pressure generated in the subcutaneous tissues during injection of the solution does not affect lidocaine absorption. The delay in absorption may allow time for some lidocaine to be removed from the tissues by suction lipectomy. In addition, the slow rise to peak lidocaine concentration in the epinephrine groups may allow the development of systemic tolerance to high lidocaine plasma levels.

Long-term fat preservation.

The injection of autologous free fat obtained by suction-assisted lipectomy for the correction of soft tissue defects is a common procedure in plastic surgery. However, unpredictable partial absorption of the injected fat often necessitates repeated harvesting and injection. Fat preservation for future re-injection is indicated to avoid repeated fat harvesting procedures. A previous study has shown that fat obtained by suction can be preserved by freezing for at least 2 weeks. The purpose of the present study was to investigate the effect of freezing autologous free fat for 7 months on the take of the fat graft. Human fat obtained by suction-assisted lipectomy was centrifuged and stored in a domestic refrigerator at -18 degrees C for 7 months. After thawing, the fat was injected into the scalp of 10 nude mice, which served as the study group. In the control group (n = 10), fresh fat was injected. Fifteen weeks later, the fat grafts were dissected out. Volumes, weights, and histological parameters were compared between the groups. The injected fat survived in both the study and the control groups but the histological parameters were significantly inferior in the frozen fat. The weight of the frozen fat was also significantly less compared with the fresh fat. The volume of the frozen fat was inferior but not significantly. Based on this in vivo experiment, it is suggested to refrain from using fat that has been frozen for 7 months or longer. The longest period and the optimal conditions for fat preservation should be further investigated.

[Method of surgical treatment of "elephantiasis" of the limb: old philosophy, new approach].

The authors had summarized more than 25-year experience of surgical treatment of patients with the lower and upper extremities lymphedema. The aspiration-resectional-plastic method of treatment of severe forms of the limb lymphedema, which intends in the first stage the resection of fibrously changed tissues, preserving the portion of slightly changed cutaneous-subcutaneous flaps and regions in projection of localization of main lymphatic collectors, under which aspiration lipectomy is performed. Postresectional wound surface is covered with special synthetic tissue. In the next stage, after appearance of granulation tissue, autodermoplasty is performed. Two-staged cutaneous plasty and repeated aspirational lipectomy provides for optimal survival of full thickness cutaneous transplants, reduction of the limb volume, improvement of the lymphatic system draining function.

[Gynecomastia. Investigation and surgical treatment].

Enlargement of the male breast, gynecomastia, commonly occurs in otherwise healthy men. If the gynecomastia is marked, surgical treatment may be necessary. Underlying disease must be considered. History, physical examination, laboratory tests and in some patients ultrasonography of the testes should be conducted prior to surgery. If the gynecomastia is due mainly due to fat, suction lipectomy alone is sufficient treatment. However, liposuction will not remove breast parenchyma, and some patients also require local excision of the parenchyma. In our experience, suction lipectomy provides a new means of acquiring better contour, with reduced morbidity and complications.

[Surgical treatment of lipodystrophies].

Esthetic body contouring has become the most common esthetic surgical procedure since the advent of liposuction. The interest in this surgery led us to focus on the physiology of adipose tissue that behaves differently according to its localisation. Besides, a better knowledge of the anatomy of the subcutaneous tissue has helped us to treat the deep and superficial adipose deposits more effectively. Many technical refinements have been proposed in order to improve the results and decrease the risks. Local infiltration allows us to remove large amounts of fat with a minimal blood loss. Syringe aspiration is less traumatic and avoids the purchase of an expensive suction pump. However, although the technique of suction lipectomy looks simple, this procedure can induce important local complications (contour deformities, skin waves, ...) and general complications (pulmonary embolism, fat embolism, cardio-pulmonary decompensation). A rigorous technique, performed by a well trained surgeon in an adequate medical environment is essential to obtain the best results with suction lipectomy. In order to correct excesses of skin on the abdomen or the thighs after an important weight loss, skin excisions will be necessary. In there cases, the scars are often wide and sometimes difficult to hide.

[Internal hemorrhage in abdominal dermolipectomy. 2 reported cases, one of which needing emergency surgical repair of aortic fissure].

The authors report two very exceptional and similar cases. In the first case, during abdominal lipectomy, the surgical team was confronted suddenly with an internal hemorrhage requiring prompt resuscitation by the anesthetist. Laparatomy revealed an aortic fissure, one centimeter above the iliac bifurcation. Bleeding was controlled by clamping the aorta, followed by suturing of the fissure. Surgery was then completed uneventfully. The second patient developed a retroperitoneal hematoma confirmed by postoperative CT scan during lipectomy and liposuction. No further treatment was required after control of the hemorrhage. No such cases have been reported in the literature and the etiology of these cases remains unclear.

Medial thighplasty, prevention of scar migration, and labial flattening.

As more people seek body contour surgery spurred on by the media's great interest in suction lipectomy and the seemingly increasing numbers of satisfied patients, we should re-examine an area where results of body contour surgery have been less satisfying, the inner thigh. In those patients whose problem remains skin flabbiness rather than excessive fat, either alone or after successful or partially successful suction lipectomy, an inner-thigh procedure is indicated.

Truncal body contouring surgery in the massive weight loss patient.

Body contouring of massive weight loss patients is the latest frontier in plastic surgery. It is important to become familiar with the presentation of these patients and with the delineation and effective treatment of their deformities. Because they usually present with circumferential excess, circumferential belt lipectomy treats their truncal contour as a unit. This article details the preoperative work-up, intraoperative technique, and postoperative course for the belt-lipectomy patient. Results and how to predict them are discussed. Complications are enumerated and suggestions offered for avoiding them.

Surgical correction of the fat neck.

This is an up-to-date review of the state of the art in the treatment of the fat neck at the University of Miami School of Medicine, based on twenty-five years of experience including several thousand cases. The combination of submental lipectomy, platysma myectomy, facelift, submandibular lipectomy, platysma myotomy, and posterior muscle traction with suture fixation has consistently produced marked improvement in the fat neck. Under this regimen, when the patient returns in five to ten years for a second lift, it is rare that the neck requires more than the skin tightening that comes with a simple facelift.
