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.     

Gynecomastia: suction lipectomy as a contemporary solution

Suction lipectomy is adapted for the correction of gynecomastia. Previous attempts using suction lipectomy for gynecomastia still required the use of sharp dissection for removal of the glandular breast tissue as well as excision of redundant skin. With this new technique, gynecomastia is corrected solely with the use of suction lipectomy. The technique is successful if the gynecomastia is due to excess fat or parenchymal hypertrophy. A 7-mm cannula is inserted first, to remove the adipose tissue. Then a 2.4-mm cannula is used to remove the glandular and ductal tissue. The 7-mm cannula is then reinserted to remove subareolar parenchyma and to make final contour adjustments. The surrounding subcutaneous tissue is easily undermined to avoid a saucer deformity and to allow for skin contraction. Patients return to full activities in 48 hours. A compressive garment is worn for 4 to 6 weeks. The results of 10 patients are discussed.     

En bloc cervical lipectomy for treatment of the problem neck in facial rejuvenation surgery

The treatment of cervical fat in facial aesthetic surgery has received much attention in recent years. Suction lipectomy has become a very popular technique for removing cervical fat because it is easy to perform and results in few complications. This paper describes the en bloc excision of cervical fat in conjunction with rhytidectomy. The senior author has treated 1,000 patients over 17 years using this technique with a high degree of patient satisfaction and minimal morbidity. Although suction lipectomy alone may be indicated for the younger patient, our experience suggests that the en bloc excisional technique is the treatment of choice in the older patient in whom a rhytidectomy is also indicated. In contrast with suction lipectomy, we have found that the en bloc excision of cervical fat allows for more anatomic dissection and facilitates removal of greater amounts of fat and better redraping of the cervical skin.     

Computerized suction lipectomy aspirator monitor for improved results in suction lipectomy

A new computerized suction aspirator monitor is described. This device offers the benefits of instantaneous and concurrent scientifically accurate readout of aspirate contents in five separate bodily areas. Thus knowledge of amounts of blood versus fat can be immediately known without resorting to guess, estimate, or cumbersome lipocrit determination by centrifuging. Advantages of such a device include better accuracy in determination of fat removal from each area, with improvement of symmetrical fat removal. More exact determination of blood loss with improved hemodynamic replacement is also more easily and safely accomplished. In an area of mystique, experience, artistry, and aesthetic appreciation which has cloaked the initial enthusiasm for suction lipectomy, a new generation of scientific accuracy is now possible. Thus accurate determination of aspirate content vis-a-vis fat and blood can now transform this procedure into a more sophisticated and scientifically accurate operation which traditionally is desired by most practitioners of suction lipectomy.     

Gynecomastia: analysis of 159 patients and current recommendations for treatment

Gynecomastia has been treated surgically in 159 patients during the past 22 1/2 years. Prior to 1980, all patients had traditional excision, which was followed by a high incidence of complications and undesired sequelae, not the least of which was that the results of this aesthetic operation were often unaesthetic. Since 1980, when suction lipectomy became the cornerstone of treatment, the results have been much better. As a result, current recommendations for treatment are as follows: If the gynecomastia is entirely due to fat, suction lipectomy alone is sufficient treatment. However, since suction will not remove breast parenchyma, those patients whose gynecomastia is due to parenchymal hypertrophy also require local excision of the parenchyma. Skin excision is rarely, if ever, necessary.     

Large-volume suction lipectomy: an analysis of 108 patients.

Suction lipectomy was initially advocated for the treatment of localized collections of fat and for the removal of less than 1500 ml of material. However, many patients wished to have multiple areas treated or had diffuse collections of fat. In such instances, the removal of over 1500 ml of material and circumferential lipectomy are necessary to provide optimal aesthetic results. However, when over 1500 ml of material is removed, anesthetic requirements, fluid replacement, and treatment of blood loss become important if the operation is to be performed safely. We have treated 108 patients who had over 1500 ml of material removed. Eight-eight percent of the patients were female; 12 percent were male. Using the body-mass index, 3 percent of patients were underweight, 70 percent were normal weight, and 27 percent were overweight. Fifty-five patients (51 percent) had 1500 to 2499 ml of material removed, 26 patients (24 percent) had 2500 to 3499 ml removed, 16 patients (15 percent) had 3500 to 4499 ml removed, and 11 patients (10 percent) had over 4500 ml removed. All patients were treated in the hospital; 44 percent were admitted after surgery. A total of 227 units of autologous and 2 units of homologous blood were transfused. As measured by a computerized monitor, the average amount of blood in the material removed from thighs was 30 percent; from abdomens, the blood loss was 45 percent. The aesthetic results were generally excellent. No complications were encountered. A few patients developed undesired sequelae, the most common of which was seroma formation, which occurred in 19 percent of those who had suction of abdominal-wall fat. We believe that large-volume suction lipectomy is safe and efficacious, provided attention is directed to such important aspects of patient care as anesthesia, fluid replacement, and blood loss.     

Subcutaneous pseudobursa secondary to suction and surgery

Suction lipectomy has been used throughout the regions of the body to remove vast amounts of subcutaneous fat. The blunt technique allows for a multiplicity of small (4 to 6 mm) channels to be created and the fat removed by suction with little disturbance of the overlying skin, the supporting septa, vessels, or nerves. Abdominolipectomy has been successfully performed for decades, in which large amounts of skin and subcutaneous fat are removed by sharp dissection. The undermining involved in an adbominolipectomy extending from the xiphoid to pubis and laterally to the level of the iliac crest and then supplemented by the suction technique has led to the formation, in some cases, of chronic seromas not relieved by multiple aspirations. Healing and contractions of these seromas causes a deformity of the overlying skin, because it is puckered and drawn upon itself. This results in the formation of a subcutaneous pseudobursa lined by collagen sheets but no epithelial cells. We present 9 patients who have demonstrated this phenomenon. We suggest that in the largest resections, safety is best served by waiting a period of at least 6 weeks between suction and subsequent resection.     

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.     

Lipodissection in body sculpturing: the dry procedure

We have used the honeycombed suction lipectomy (wet and/or dry) in over 700 patients. It represents a major advancement in the treatment of the localized adiposities of the body. Its advantages are eliminating the need for long, unsightly scars and reducing operating time and morbidity. Selection of appropriate patients is of paramount importance for reliable results because this technique is truly sculpting of the soft tissues. Results improve also with the proper training and experience of the surgeon. The indications and complications have been discussed. This technique (honeycombed suction lipectomy) appears more reliable than suction curettage that employs sharp dissection.     

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.     

The effect of epinephrine on blood loss during suction lipectomy

In a prospective, double-blind, controlled study on 26 consecutive patients who underwent suction lipectomy, the injection of epinephrine (1:250,000, 1:500,000, or 1:1,000,000) was not found to decrease fluid/blood loss when compared with saline injection or no injection at all. Since our study fails to support the use of epinephrine to lessen fluid/blood loss during suction lipectomy, we have abandoned its use in that procedure.     

Suction mammaplasty: the use of suction lipectomy to reduce large breasts

The use of suction lipectomy to reduce breast volume is described. The technique applies only to a very limited group of patients whose nipple-areola complexes are normally located and whose enlargement is primarily fibrofatty in nature. Suction mammaplasty can be used as a sole technique in congenital asymmetry or in post-reduction enlargement or asymmetry.     

Autologous fat transplants influence compensatory white adipose tissue mass increases after lipectomy

Direct tests of the hypothesized total body fat regulatory system have been accomplished by partial surgical lipectomy. This usually results in the restoration of the lipid deficit through compensatory increases in nonexcised white adipose tissue (WAT) masses of ground squirrels, laboratory rats, and mice, as well as Siberian and Syrian hamsters. We challenged this hypothesized total body fat regulatory system by testing the response of Siberian hamsters to 1) lipid deficits [lipectomy; primarily bilateral epididymal WAT (EWAT) removal], 2) lipid surfeits (addition of donor EWAT with no lipectomy), 3) no net change in lipid [EWAT or inguinal WAT (IWAT) lipectomy with the excised fat replaced to a new location (autologous)], 4) lipectomy with the same pad (EWAT lipectomy only) added from a sibling (nonautologous), and 5) sham surgeries for each treatment. Food intake generally was not affected. Body mass was not affected across all treatments. Grafts approximately 3 mo later had normal appearance both macro- and microscopically and were revascularized. The normal lipectomy-induced compensatory increases in nonexcised WAT masses surprisingly were exaggerated with autologous EWAT transplants, but not for autologous IWAT or nonautologous EWAT transplants. There was no compensatory decrease in native WAT masses with nonautologous EWAT additions. Collectively, only lipectomy triggered reparation of the lipid deficit, but the other manipulations did not, suggesting a system biased toward rectifying decreases in lipid or an inability of the hypothesized total body fat regulatory system to recognize WAT transplants.     

Quantitative analysis of blood and fat in suction lipectomy aspirates

This study of suction lipectomy aspirates from 15 consecutive patients was undertaken to biochemically quantitate the blood-to-fat ratios of the aspirates. A wide variation in the blood-to-fat ratios (8 to 54 percent) was noted, but the authors failed to demonstrate any relationship between the blood-to-fat ratios and the suction lipectomy operative site. Prophylactic measures to allow treatment of patients in a consistently safe manner include carefully screening of patients to exclude those with bleeding disorders or significant illnesses, perioperative oral iron therapy, infiltrating the operation site with a dilute epinephrine solution, hydrating the patients adequately perioperatively, using smaller-diameter cannulas for the aspiration, minimizing aspiration once the aspirate turns grossly bloody, and limiting the aspirate to a volume of less than 1750 ml for any operative procedure.     

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.     

Fat redistribution following suction lipectomy: defense of body fat and patterns of restoration

No randomized studies in humans have examined whether fat returns after removal or where it returns. We undertook a prospective, randomized-controlled trial of suction lipectomy in nonobese women to determine if adipose tissue (AT) is defended and if so, the anatomic pattern of redistribution. Healthy women with disproportionate AT depots (lower abdomen, hips, or thighs) were enrolled. Baseline body composition measurements included dual-energy X-ray absorptiometry (DXA) (a priori primary outcome), abdominal/limb circumferences, subcutaneous skinfold thickness, and magnetic resonance imaging (MRI) (torso/thighs). Participants (n = 32; 36 ± 1 year) were randomized to small-volume liposuction (n = 14, mean BMI: 24 ± 2 kg/m(2)) or control (n=18, mean BMI: 25 ± 2) following baseline. Surgery group participants underwent liposuction within 2-4 weeks. Identical measurements were repeated at 6 weeks, 6 months, and 1 year later. Participants agreed not to make lifestyle changes while enrolled. Between-group differences were adjusted for baseline level of the outcome variable. After 6 weeks, percent body fat (%BF) by DXA was decreased by 2.1% in the lipectomy group and by 0.28% in the control group (adjusted difference (AD): -1.82%; 95% confidence interval (CI): -2.79% to -0.85%; P = 0.0002). This difference was smaller at 6 months, and by 1 year was no longer significant (0.59% (control) vs. -0.41% (lipectomy); AD: -1.00%; CI: -2.65 to 0.64; P = 0.23). AT reaccumulated differently across various sites. After 1 year the thigh region remained reduced (0.77% (control) vs. -1.83% (lipectomy); AD: -2.59%; CI: -3.91 to -1.28; P = 0.0001), but AT reaccumulated in the abdominal region (0.64% (control) vs. 0.42% (lipectomy); AD: -0.22; CI: -2.35 to 1.91; P = 0.84). Following suction lipectomy, BF was restored and redistributed from the thigh to the abdomen.     

The influence of permanent magnetic field therapy on wound healing in suction lipectomy patients: a double-blind study

The authors present their experience with the healing influence of permanent magnets on postoperative wounds. The responses of 20 patients who underwent suction lipectomy and postoperative negative magnetic field therapy were studied in a double-blind fashion. Magnets in the form of patches (10 patients) or sham magnet patches (10 patients) were placed over the operative region in each of the patients. Pain, edema, and discoloration (ecchymosis) were evaluated at 1, 2, 3, 4, 7, and 14 days postoperatively. Our results show that the treatment group had significant reductions in pain on postoperative days 1 through 7, in edema on days 1 through 4, and in discoloration on days 1 through 3 when compared with the control group. These results demonstrated that commercially available magnets have a positive influence on the postoperative healing process in suction lipectomy patients.     

Toxic shock syndrome after suction lipectomy

We present a case of toxic shock syndrome with necrotizing fasciitis after suction lipectomy. The patient underwent aesthetic suction lipectomy of the abdomen, buttocks, and thighs during an office procedure by a cosmetic surgeon. On postoperative day 2, the patient was referred to the emergency department of our hospital because of pain. On admission, the patient was in toxic shock. She required intensive medical treatment for about 1 month, along with psychiatric help to adapt after the illness. Although toxic shock syndrome is a rare postoperative complication, every plastic surgeon should be acquainted with it. A combination of early recognition, diagnosis, and aggressive supportive therapy is the only successful treatment.     

A national survey of complications associated with suction lipectomy: a comparative study

In March of 1988, a survey form was sent to all 2695 U.S. and Canadian members of the American Society of Plastic and Reconstructive Surgeons. Nine-hundred and thirty-five members responded, for a response rate of 34.7 percent. The purpose of the survey was to ascertain the total number of major liposuction, dermatolipectomy, and abdominoplasty procedures performed from January of 1984 to January of 1988 and to compare nine specific complications that are associated with these three procedures. The 935 surgeons reported a total of 112,756 procedures performed: major liposuction (75,591), dermatolipectomy (10,603), and abdominoplasty (26,562). Nine major complications were surveyed: mortality, myocardial infarction, cerebrovascular accident or transient ischemic attack, pulmonary thromboembolism, fat embolism, major skin loss, anesthesia complication, transfusion complications, and deep venous thrombosis. The findings in this survey showed, when comparing these three procedures and the nine types of complications, that the complication rate for major suction lipectomy was 0.1 percent, for dermatolipectomy 0.9 percent, and for abdominoplasty 2.0 percent. Fat emboli did not prove to be a significant factor associated with any of the three procedures. However, of the 15 reported deaths (major liposuction 2, dermatolipectomy 2, and abdominoplasty 11), pulmonary thromboembolism was the causative factor in 9 deaths (60 percent). Based on these analyzed data, we feel that major suction lipectomy has a low complication rate and is a reasonably safe procedure.     

Effects of white adipose tissue grafts on total body fat and cellularity are dependent on graft type and location

Surgical removal of body fat (lipectomy) triggers compensatory increases in nonexcised white adipose tissue (WAT), thus restoring adiposity levels in many species, including Siberian hamsters. In Siberian hamsters, when their lipectomized WAT is transplanted to another site (autologous grafts, no net change in body fat), healthy grafts result, but the lipectomy-induced compensatory increases in nonexcised WAT masses are exaggerated, an effect that apparently occurs only when the grafts contact intact WAT. When WAT is added to nonlipectomized hamsters to increase body fat, native WAT pads do not decrease. Thus WAT addition or removal-replacement does not induce compensatory WAT responses consistent with total body fat regulation as does WAT subtraction. Therefore, we tested whether the exaggerated response to lipectomy occurring with autologous WAT transplantation is dependent on graft site placement and whether the donor graft source [inguinal or epididymal WAT (IWAT, EWAT), sibling vs. nonsibling] affected body fat responses to WAT additions in nonlipectomized hamsters. Lipectomized hamsters received subcutaneous autologous EWAT grafts placed remotely from other WAT (ventrum) or in contact with intact WAT (dorsum), whereas intact hamsters received EWAT or IWAT grafts from sibling or nonsibling donors. The exaggerated response to lipectomy only occurred when grafts were in contact with intact WAT. EWAT, but not IWAT, additions to nonlipectomized siblings or nonsiblings increased native IWAT and retroperitoneal WAT mass but not EWAT mass compared with controls. Collectively, WAT transplantation to either lipectomized or nonlipectomized hamsters increased body fat contingent on graft contact with intact or native WAT.
