Suction lipectomy of the neck

Suction lipectomy of the neck has been advocated in other reports. However, because of skin laxity, a simultaneous face/neck lift has been performed usually. In this series of 49 patients, ages 18 to 73, removal of submandibular fat was performed by suction lipectomy. A simultaneous face/neck lift was not done. In addition, no skin was excised. On the contrary, the apparent excess skin was found to be required for contouring. Approximately one-third of the patients had a simultaneous chin implant. Others had different aesthetic surgical procedures performed during the same operation. The removal of neck fat by suction has proven to be more efficacious than excisional methods of lipectomy. The risks of operation have been found comparable to suction lipectomy performed in other anatomic locations.     

Defatting of flaps by means of suction-assisted lipectomy

Single-stage debulking of flaps using suction-assisted lipectomy in combination with skin excision is a safe and reliable procedure with results comparable to conventional multistaged surgical techniques. Three representative cases are presented that demonstrate the efficacy of suction-assisted lipectomy as an adjunctive procedure for flap defatting.     

Comparison of surface electromyographic (sEMG) activity of submental muscles between the head lift and tongue press exercises as a therapeutic exercise for pharyngeal dysphagia

Objective: The present study compared surface electromyographic (sEMG) activity obtained from the submental muscle group for a tongue press and a head lift exercise as potential therapeutic exercises for dysphagic elderly. Materials and methods: Fifty‐three healthy volunteers with a mean age of 35.3 participated in this study. Subjects were required to perform an isometric task, pressing their tongue against the hard palate, and an isotonic task requiring sustained lingual force against the hard palate. Pressure sensors were used to measure the amount of lingual pressure against the hard palate. Submental sEMG data from these tasks were compared with those obtained from the isometric and isotonic aspects of a head lift exercise. Results: No sEMG differences were identified between the isometric tongue press task and head lift exercise. Isotonic tongue press exercises resulted in significantly higher maximum and mean sEMG values compared with the isotonic head lift exercise (p < 0.05). The submental sEMG activity from the tongue press exercise was equal (isometric) to, or greater (isotonic) than comparable muscle activation obtained during the head lift exercise. Conclusions: The tongue press exercise may be less strenuous than the head lift exercise while achieving the same therapeutic effect.     

SMAS-platysma face lift

Correction of laxity in the submental area and of hypertrophic neck cords has been enhanced with the SMAS-platysma face life over that which was achieved with a standard skin face lift. Evaluation of a 6-year experience with the SMAS-platysma face lift reveals that the operation can be safely performed with an acceptably low incidence of complications. The incidence of hematoma and associated complications is less than that which occurs when cervical and submental defatting is performed in conjunction with a skin face lift.     

Face and neck suction-assisted lipectomy associated with rhytidectomy

A technique is described in which suction-assisted lipectomy is used for excessive fat removal in association with the standard rhytidectomy. It is safe, reliable, and can be performed through a small horizontal submental incision. A more natural appearing neck is produced by adjusting the amount of fat removed. Areas previously considered dangerous for excision because of possible damage to branches of the facial nerves, such as the cheek areas, jowls, parotid, and nasolabial folds, can now be approached.     

Skin retraction following suction lipectomy by treatment site: a study of 500 procedures in 458 selected subjects

I identified 500 suction lipectomy procedures involving sites on the body and in the cervicofacial region in 458 selected patients and studied the influence of treatment site on postoperative skin retraction by comparing preoperative and postoperative skin condition. Postoperative skin condition was evaluated first in the immediate postoperative period (second or third day); then at a more remote date (after at least 2 months of follow-up). On the body, restoration of the preoperative condition of the skin was obtained in 94.6 percent of treatment sites in the immediate postoperative period; after a longer follow-up, this proportion was 87.9 percent because of delayed development of modifications. The time interval needed to obtain a stable result increased with increasing age, regardless of the nature of this result, as well as with the total amount of fat removed. On the neck, liposuction improved or even eliminated preexisting skin looseness, and this improvement was even more noticeable as follow-up increased. The neck thus appears as the site of choice for suction lipectomy. On the face, in contrast, favorable results deteriorated over time, a finding that leads me to advocate combination with a face-lift whenever ptosis is present. Thus treatment site obviously has a substantial impact on the potential of the skin for retracting postoperatively.     

Evaluation of a technique designed to correct nasolabial folds.

This is a long-term follow-up of correction of nasolabial folds in conjunction with face lift that was first published in 1987. In the last 200 face lifts, nasolabial lipectomy has been carried out in 90 percent. Refinements and extensions of the procedure are also described with case illustrations.     

Effect of liposuction on skin perfusion

Clinical reports of full-thickness skin necrosis have raised concern about the thermal and dermal ischemic effects of ultrasound-assisted liposuction. The purpose of this study was to evaluate skin perfusion in patients treated with ultrasound-assisted liposuction or suction-assisted liposuction. Patients (n = 75) were studied prospectively in the perioperative period surrounding their suction-assisted liposuction (31 patients) or ultrasound-assisted liposuction (64 patients). The laser Doppler flowmeter was used to monitor skin perfusion in the treated regions preoperatively, intraoperatively, and postoperatively at a series of time intervals. The effects of the anesthetic, wetting solution, and type of liposuction (suction-assisted liposuction or ultrasound-assisted liposuction) on skin perfusion were measured. Anesthetic induction significantly increased measured skin perfusion. Wetting solution infusion significantly decreased skin perfusion (-57.4 percent +/- 2.0) by 15 minutes postinfusion. Skin perfusion in the ultrasound-assisted liposuction group was significantly greater than that of the suction-assisted liposuction patients at 1 hour, 1 day, and 1 week postoperatively; however, by 2 to 5 weeks, no difference in skin perfusion was noted and skin perfusion had returned to preoperative levels in both groups. Although skin perfusion in the suction-assisted liposuction group was significantly lower than in the ultrasound-assisted liposuction group in the early postoperative period, no differences in skin perfusion between the groups were noted beyond 1 week postoperatively, suggesting that neither technique impairs perfusion.     

The trauma of suction-assisted lipectomy cannula on flap circulation in rats.

The effect of suction-assisted lipectomy on cutaneous blood vessels of inguinal skin flaps was studied and compared in 191 rats. Different types of cannula tips were used; the number of passes was standardized. In one experiment, following suctioning, 3 X 2 cm groin island flaps based on inferior epigastric pedicles were raised and then reattached. Fluorescein dye study and microangiography were performed to evaluate flap viability. Flap survival was determined clinically and by histologic examination on the fifth postoperative day. Three-sided inguinal random-pattern flaps were raised in a second experiment and reattached following suctioning. On the fifth postoperative day, surviving flap areas were measured using standard photographs and an imaging computer and were compared with controls. Results showed that cannula passes accompanied by vacuum are harmful to vessels, while those unaccompanied by vacuum are not. The greater the number of suctioning passes, the more trauma there is to vessels and the greater is the likelihood of flap necrosis. Conical and spatula tips were more harmful to vessels than spherical, cobra, keel cobra, or Fournier tips. These results support the conclusion that suction-assisted lipectomy enhances the possibility of skin necrosis by traumatizing the vascular pedicle of a flap, especially when it is used as an adjunct to flap elevation.     

Comparative study of survival of autologous adipose tissue taken and transplanted by different techniques

In recent years, adipocytes obtained by suction-assisted lipectomy have been used for implantation by injection methods. This study is designed to assess the appearance of suctioned and excised adipose tissue and its survival after being injected or implanted into different tissues (0.5 cc into the rectus muscle and 0.5 cc into the dorsal ear skin) of New Zealand White rabbits. The results showed that significant numbers of adipocytes were ruptured after suction procedures. The intact cells represented approximately 10 percent of the fat cell population. Fat cells in aspirated and excised samples remained intact and did not differ histologically. After being injected into tissue, adipocytes appeared to survive better for a short term in a more vascularized bed (rectus muscle) than in a low vascular area (ear dermis). Long-term studies at 6- to 9-month intervals revealed transplanted adipose tissue, taken by suction or excision, being replaced with fibrosis, although cystic spaces and only a small number of surviving adipocytes were still present. Insulin did not show any protective effects on survival of the adipocytes during their transplantation.     

Suction lipectomy: complications and results by survey

In October of 1983, we sent a questionnaire on suction lipectomy to 2524 U.S. and Canadian members of the American Society of Plastic and Reconstructive Surgeons. Six-hundred and twelve plastic surgeons returned questionnaires (24.2 percent response rate). One-hundred and seven responding surgeons reported 1573 operations in which suction lipectomy with or without skin excision was used for 2685 procedures on various parts of the body. In the subset of 1249 operations in which suction lipectomy only was used to treat 2261 anatomic areas, surgeons reported greater than 80 percent good or excellent aesthetic results. The overall complication rate was 9.3 percent. The most frequent complications were persistent hypesthesia (2.6 percent), seroma (1.6 percent), and persistent edema (1.4 percent). Skin pigmentation, pain, hematoma, infection, and slough each occurred with an incidence of 1.0 percent or less. Based on the results of this survey, suction lipectomy is a valuable new modality for surgical improvement of body contour.     

Lip augmentation with superficial musculoaponeurotic system grafts: report of 103 cases.

Many patients suitable for a lip augmentation are of face lift age, and could benefit from a simultaneous lip enhancement during the rhytidectomy procedure. The healthy, live superficial musculoaponeurotic system (SMAS) tissue obtained from the face lift can be recycled and grafted with minimal additional operating time. From April of 1995 to January of 2000, 103 patients (99 women and four men) underwent a lip augmentation procedure by the senior author (N.L.) using SMAS grafts harvested from a simultaneous rhytidectomy. Indications for surgery were purely aesthetic in all 103 cases. The surgical technique used for the SMAS graft lip augmentation is as follows: Using a narrow tenotomy scissors, an intramuscular tunnel was created with blunt and sharp dissection across the lip. The graft, obtained from the posterior edge of the SMAS dissection, is left as long as possible, and is pulled through the tunnel with a tendon forceps. The lips are then stretched manually from the central point upward and downward, respectively. It is important to avoid suturing the ends of the graft into the closure; the grafts should be allowed to move freely, to avoid postoperative tethering on smiling or mouth opening.Most patients expressed some initial concern with their early appearances caused mainly by the swelling. By 2 weeks, most patients were extremely pleased with the size and shape, and their main concern was that the lip fullness would shrink even more. By 3 to 4 weeks, shrinkage largely ceased and the correction remained for varying periods, some as long as 5 years. A sampling of the results was obtained by means of a questionnaire mailed to all patients having undergone the SMAS graft lip augmentation. Fifty-four patients (52 percent) returned the questionnaire with their responses. Of those who responded to the survey, 42 patients (78 percent) reported fuller lips than before their operation. Significantly, 11 of 14 patients (79 percent) followed up after 24 months postoperatively reported fuller lips and excellent or good results. Complications and unsatisfactory results were very rare, occurring generally at the beginning of the learning curve of the series.SMAS grafts are useful for long-lasting lip augmentation, producing a youthful appearance by adding natural, soft roundness and fullness to lips without the artificial look and feel of synthetic material.     

Classification and management of gynecomastia: defining the role of ultrasound-assisted liposuction

Gynecomastia, or excessive male breast development, has an incidence of 32 to 65 percent in the male population. This condition has important physical and psychological impacts. Advances in elucidating the pathophysiology of gynecomastia have been made, though understanding remains limited. Recommendations for evaluation and workup have varied and are often arbitrary. A diagnostic algorithm is suggested, with emphasis on a comprehensive history, physical examination, and minimizing unnecessary diagnostic testing. Medical management has had limited success; surgical therapy, primarily through excisional techniques, has been the accepted standard. Although effective, excisional techniques subject patients to large, visible scars. Ultrasound-assisted liposuction has recently emerged as a safe and effective method for the treatment of gynecomastia. It is particularly efficient in the removal of the dense, fibrous male breast tissue while offering advantages in minimal external scarring. A new system of classification and graduated treatment is proposed, based on glandular versus fibrous hypertrophy and degree of breast ptosis (skin excess). The authors' series of 61 patients with gynecomastia from 1987 to 2000 at the University of Texas Southwestern Department of Plastic Surgery demonstrated an overall success rate of 86.9 percent using suction-assisted lipectomy (1987 to 1997) and ultrasound-assisted liposuction (1997 to 2000). The authors have found ultrasound-assisted liposuction to be effective in treating most grades of gynecomastia. Excisional techniques are reserved for severe gynecomastia with significant skin excess after attempted ultrasound-assisted liposuction.     

Corset platysmaplasty

Contemporary surgery to rejuvenate the aging neck commonly includes some type of platysma modification. Most currently used methods of platysmaplasty involve upper midline plication, muscle resection, or transection. These methods, however, have their shortcomings, often producing necks that display persistent or recurrent paramedian muscle bands, visible submandibular gland bulges, and various contour irregularities. Corset platysmaplasty was developed to avoid these postoperative imperfections. After an adequate subcutaneous and subplatysmal lipectomy has been performed, the two medial edges of the platysma are joined together with a continuous suture that runs down, and up, and down almost the full-height of the neck to create a smooth, flat, multilayered seam, leaving no free muscle edges to return as visible bands. Progressive side-to-side tightening along the midline seam defines the "waistline" of the neck. Additional submandibular suturing is then done to create strong, flat, vertical muscle pleats that correct submandibular gland bulging and refine the jawline and anterolateral neck contours. Corset platysmaplasty is useful for all patients with visible paramedian muscle bands and all patients who would benefit from having a decussated upper neck platysma opened for submuscular defatting, including patients with oblique, palpably firm necks that suggest a vertically short platysma muscle or low-lying hyoid bone. The paper is based on the results with 75 patients having undergone corset platysmaplasty, most having been followed for 1 to 3 years.     

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.     

Periareolar approach for the correction of congenital symmastia

This report elucidates the continued and relatively rare problem of congenital symmastia and its surgical repair without concomitant bilateral breast reduction. This case highlights the use of suction-assisted lipectomy techniques to address the excess fat in the presternal web and a periareolar approach for access to the intermammary space. The periareolar incision allows for the use of a concealed approach and the avoidance of a central scar that could result in hypertrophy or keloid formation, especially in this patient who is more prone to hypertrophic scarring. Furthermore, plication of the central web dermis to the sternal periosteum in a more superior position serves to not only correct the symmastia but also redrape the excess skin and restore the blunted inframammary folds.     

Belt lipectomy for circumferential truncal excess: the University of Iowa experience

When some patients with circumferential truncal excess undergo traditional abdominoplasty, the trunk is not addressed as a unit. Belt lipectomy, a procedure that combines abdominoplasty with circumferential excision of skin and fat, is often more ideal for these patients. In this article, the authors review the literature on belt lipectomy and evaluate their series of 32 patients who underwent belt lipectomy at the University of Iowa. The evolution and current preoperative markings, intraoperative surgical technique, and postoperative care are described. The patients' charts and their preoperative and postoperative photographs were examined retrospectively. It was found that belt lipectomy improved abdominal contour, abdominal wall laxity, mons pubis ptosis, back rolls, waist contour, and buttocks contour. Initially, the procedure was performed on post-weight-reduction patients only, but its indications were extended to three other groups: patients who were 30 to 50 pounds overweight, patients of normal weight who desired a significant overall truncal improvement, and an obese patient with persistent intraabdominal excess. The improvements were significant in all groups of patients except for the latter patient. Complications included a 37.5 percent seroma rate, a 9.3 percent pulmonary embolus rate, and one dehiscence that required reoperation. The authors concluded that belt lipectomy should be seriously considered for patients who present with circumferential truncal excess and for a select group of normal-weight patients. It is not recommended for the obese patient with excessive intraabdominal content. Furthermore, belt lipectomy should be undertaken only in patients who are well informed about the possible risks and complications.     

Deep venous thrombosis and pulmonary embolus after face lift: a study of incidence and prophylaxis

Deep venous thrombosis and pulmonary embolus are known risks of surgery. However, the incidence of these conditions in face lift is unknown. In this study, the incidence of deep venous thrombosis/pulmonary embolus after face lift is studied and factors associated with thromboembolic complications are evaluated. One-third of the active members of the American Society for Aesthetic Plastic Surgery were randomly selected. Participating surgeons completed a one-page survey providing information on face-lift procedures during a 12-month study period. A response rate of 80 percent was achieved, with 273 of the 342 surgeons responding to the survey. A total of 9937 face-lift procedures were reported in the 1-year study period. There were 35 patients with deep venous thrombosis (0.35 percent), 14 patients with pulmonary embolus (0.14 percent), and 1 patient death in the series. Although 43.5 percent of patients underwent face lift under general anesthesia, 83.7 percent of deep venous thrombosis/pulmonary embolus events occurred with general anesthesia. For prophylaxis for deep venous thrombosis/pulmonary embolus, 19.7 percent of the surgeons used intermittent compression devices, 19.6 percent used thromboembolic disease hose or Ace wraps, and 60.7 percent used no prophylaxis. Of patients developing deep venous thrombosis/pulmonary embolus, 4.1 percent were treated prophylactically with intermittent compression devices, 36.7 percent with thromboembolic disease hose/Ace wraps, and 59.2 percent with no prophylaxis. It was found that deep venous thrombosis/pulmonary embolus after face lift is a measurable complication experienced by one of nine surgeons surveyed. Deep venous thrombosis/pulmonary embolus is more likely to occur when the procedure is performed under general anesthesia. The majority of plastic surgeons surveyed used no prophylaxis for deep venous thrombosis when performing face-lift procedures. Intermittent compression devices were associated with significantly fewer thromboembolic complications, whereas Ace wrap/thromboembolic disease hose afforded no protection against deep venous thrombosis/pulmonary embolus when used alone. In conclusion, aesthetic surgeons should consider adopting intermittent compression devices when performing face lift under general anesthesia.     

The ptotic (witch's) chin deformity: an excisional approach.

Ptosis of the chin pad is common and can be seen in patients of all ages. It may be associated with too little or (at times) too much anterior chin projection. Often there is an associated deep submental skin crease present. Frequently, the primary concern of the patient is the appearance or exaggeration of chin ptosis in smiling ("dynamic" ptosis). This report describes a flexible approach to the correction of developmental (and some iatrogenic) ptotic chin deformities. The key element in the approach is the direct excision of sagging or excess chin fat, muscle, and skin. No attempt is made to reposition or lift ptosis-prone soft tissues. If a deep submental skin crease is present, it too is excised. If the chin needs added anterior projection, it is accomplished with a stable alloplastic chin implant. The approach is uniquely suited to correct anterior overprojection caused by an excess of soft tissue at the front of the chin and has been successful in correcting the "dynamic" ptosis that appears with smiling.     

Cigarette smoking and face lift: conservative versus wide undermining

The effects of cigarette smoking on the skin flaps of the face lift procedure are discussed. Reported elsewhere is a significant incidence of skin slough in smokers with use of wide undermining techniques. This complication is thought to be due to the vasoconstrictive effects of nicotine on the peripheral circulation. Our group has employed a conservative bilateral undermining technique in 407 face lifts. Of these, 32.4 percent were smokers and 67.6 percent were nonsmokers. No cases of skin slough were encountered. Our conservative undermining technique is briefly discussed. Among its advantages are shorter operative time, use of less local and/or general anesthesia, less intraoperative bleeding, adequate exposure for SMAS and platysmal surgery, and snugger skin closure without the risk of flap necrosis. As shown by our statistics, it is a safer procedure in smokers than the usually performed more radical procedure.
