Advanced techniques in liposuction.

Liposuction is a procedure that has been widely used since the 1980s. The introduction of the tumescent technique in 1987 greatly improved the safety of the procedure. Innovative techniques and equip ment modifications have continued to evolve, broadening the scope of application and improving the results that can be obtained. This article discusses several recent advancements in liposuction techniques. Three-Dimensional Tumescent Liposculpture (William R. Cook, Coronado, CA) was developed to view contiguous areas of the body as a unit rather than to simply suction fat from one particular area. Advanced techniques have improved the ability to liposuction difficult areas, such as the arms, calves, medial thighs, and the male breast. A combination of syringe-suction and machine-assisted liposculpture is sometimes used. Tumescent liposculpture has been combined with pulsed CO2 laser surgery to produce a more effective and less invasive treatment for the aging face, neck, and jowls. External ultrasound-assisted liposculpture can produce excellent results.

Computerized tomography of the glottis after intracordal autologous fat injection.

According to the committee on speech, voice, and swallowing disorders of the American Academy of Otolaryngology-Head and Neck Surgery, various surgical methods such as laryngeal framework surgery, laryngeal re-innervation, and injection laryngoplasty might be used to palliate inferior laryngeal nerve paralysis. In the present case report we document the survival and exact location of the boluses of autologous fat in one patient in whom this material was used for injection laryngoplasty.

[Body contouring by removal of skin and fatty tissue].

There is an increasing demand for surgical correction of the body contour in the modern society. We present a summary of the indications and techniques of the most important interventions on the abdomen, hip, thigh and arm. The operations aim at the correction of localized excesses of fat and skin tissue with liposuction and dermolipectomy. Liposuction is performed through small skin incisions, which results in minimal scar formation; and which is associated with minimal complication rates. The indication for liposuction is restricted to the conditions in which the overlying skin is capable to retract and adapt itself to the new contour. Otherwise, or if an excess of skin is the cause of the deformity, a dermolipectomy is required. In this case, the incisions are chosen in a way that the resulting scar may be hidden as well as possible.

[Painful lipoma?].

The adiposis dolorosa (Dercum's disease) was described already in 1892. Many questions about its physiopathological mechanism are still unresolved. Presentation of a patient with this disease is reported, followed by a brief review of the literature, where the pathogenesis, the differential diagnosis and the therapeutical approaches of this syndrome are especially pointed out.

[Madelung's disease (benign symmetric lipomatosis): still a mystery?].

The benign symmetric lipomatosis (Madelung's disease) is frequently associated with alcoholism. After 150 years of history, many questions about its physiopathological mechanism are still unresolved. Presentation of a patient with this rare condition is reported, followed by a review of the literature, where the pathogenesis, the differential diagnosis and the surgical approach of this syndrome are especially pointed out.

[Water jet dissection in fatty tissue].

BACKGROUND: The first report about the use of water-jet dissection in surgery dates 1982. The advantage compared to conventional cutting is the preservation of vessels and nerves, thus facilitating the precise coagulation thereafter. Devices of the new generation with coherent jet are used in liver surgery in order to reduce blood loss. The use of water-jet dissectors in other fields of surgery is currently under investigation. The preparation of vessels in fatty tissue is of special interest for plastic surgeons. The technical parameters of the hydro- or water-jet device have to be optimised. METHOD: Abdominal fat tissue of fresh cadavers was cut under standardised conditions with different parameters of the dissector. The depth of the cuts and the morphology of the blood vessels were analysed. RESULTS: Between 20 and 60 Bar cutting pressure of the water-jet and one single pass the cuts are 8 mm deep. Deeper cuts can be achieved by repeated application on the same cut. When using 40 Bar and 5 passes the cutting depth is 1.7 cm. Higher pressure as 50 or 60 Bar do not lead to deeper cuts. The water-jet dissection leads to a water uptake of the cut tissue. Morphologically all the vessels, lying in the cut are undamaged if the pressure doesn't exceed 40 Bar pressure range. CONCLUSION: The optimal pressure for water-jet dissection of fatty tissue lies between 30 and 40 Bar. Higher pressure does not lead to deeper cuts, but increases the risk of vessel damage. The vessels in the remain morphologically intact if he cutting pressure lies below 50 Bar. The effect of the mechanical irritation of the vessels has to be investigated in vivo, before using the water-jet dissector for preparation of blood vessels in humans e.g. for flap dissection.

Liposuction for axillary hyperhidrosis.

A 23-year-old woman presented with a 10 year history of excessive sweating (hyperhidrosis), mostly in the axillae, and to a lesser extent the groin and hands. Initial treatment with a sedative antihistamine and topical Driclor (aluminium chloride hexahydrate in 2% alcohol) for 14 weeks resulted in no improvement. Axillary liposuction, a short and simple procedure, then produced a very satisfactory result.

Liposuction in cosmetic dermatology.

Liposuction is one of the most frequently performed cosmetic procedures in the world today. The central role of dermatologists in evolving many of the procedural methods now used is discussed. Tumescent anaesthesia and the associated tumescent technique proper allow liposuction to be performed safely and effectively in an outpatient setting. An overview of the technique and applications is presented.

Liposuction in Dercum's disease: impact on haemostatic factors associated with cardiovascular disease and insulin sensitivity.

OBJECTIVE: To study the impact of adipose tissue removal by liposuction on factors associated with increased risk of cardiovascular atherosclerotic disease within the coagulation and fibrinolytic system and glucose metabolism. DESIGN, SETTING AND SUBJECTS: Liposuction was performed in 53 patients with Dercum's disease. The levels of fibrinogen, von Willebrand factor antigen (VWF:Ag) and plasminogen activator inhibitor type 1 activity (PAI-1) were measured preoperatively, and 2 weeks, 4 weeks and 3 months postoperatively. In a subsample of 10 patients, insulin sensitivity was determined before and 2-4 weeks after surgery using the 2-h euglycaemic hyperinsulinaemic clamp technique. The study was performed as a single-centre study. MAIN OUTCOME MEASURE: Fibrinogen, PAI-1 and VWF:Ag levels, and glucose uptake before and after removal of adipose tissue. RESULTS: Weight reduction was sustained throughout the follow-up period with a mean decrease from 90.7 to 86.6 kg (P < 0.0001). There was a slight increase in levels of coagulation factors 2 and 4 weeks postoperatively, probably in reaction to the surgical trauma. After 3 months the values had returned to preoperative levels except for PAI-1, which still showed a slight increase (P < 0.05). In the subsample of 10 patients, glucose uptake was improved (P < 0.05) from a short-term perspective after surgery. CONCLUSION: Surgical removal of adipose tissue, without change in lifestyle, does not seem to improve the levels of coagulation and fibrinolytic factors associated with cardiovascular atherosclerotic disease, whereas glucose takeup may be facilitated and insulin sensitivity increases from a short-term perspective.

Axillary osmidrosis treated by partial removal of the skin and subcutaneous tissue en bloc and apocrine gland subcision.

BACKGROUND: Axillary osmidrosis can be treated with many methods, but local surgery is the treatment of choice. METHODS: Forty-three patients (32 females and 11 males, average age 20.3 years) were treated by partial removal of the skin and subcutaneous tissue en bloc and follicular clipping of the adjacent area. All operations were performed with local anesthesia in an outpatient setting. RESULTS: Follow-up ranged from 2 to 47 months (mean: 13.4 months). Forty-one patients (95%) had good results, two (5%) were fair, and none were poor. No recurrences were seen. The wound complication rate was 3.5% for axillae and 7% for patients. There were no scar contractures or limitations of arm abduction. CONCLUSION: This combined surgical method can eliminate malodor and has a low wound complication and recurrence rate. Though the transient and conspicuous scar is the chief drawback of this method, it is a simple, safe, effective and inexpensive method for treating axillary osmidrosis.

[Lipoedema--current status, new perspectives].

Because of the lifelong and often progressive course and the mental trauma to the patients, lipoedema is an important dermatologic disorder. Complex physical therapy programs were introduced as a standard therapy years ago and can achieve an impressive oedema reduction. Liposuction in tumescent local anesthesia with vibrating microcannulas has proved to be a new effective treatment. A targeted and permanent reduction of the fat tissue leads to an increased quality of life due to an improved appearance, reduced tendency to swelling and less pain.

Ultrasound-assisted lipoplasty.

BACKGROUND: Ultrasound-assisted lipoplasty (UAL) has been associated with particular types of complications and uncertain long-term effects arising from interactions between ultrasonic energy and living tissue. The present review seeks to address these issues. METHODS: Search strategy Three search strategies were devised to retrieve literature from Medline, Current Contents, Embase and Cochrane Library databases up until April 2000. Study selection Inclusion of papers was largely determined using a predetermined protocol. English language papers were selected. Acceptable study designs included randomized controlled trials, controlled clinical trials, case series or case reports. Data collection and analysis Thirty-six papers met the inclusion criteria. They were tabulated and critically appraised in terms of methodology and design, outcomes, and the possible influence of bias, confounding and chance. Other papers were also included to provide background material. RESULTS: There was little high-level evidence available comparing UAL and suction-assisted lipoplasty (SAL), with no conclusive evidence that UAL has a safety benefit, although low-quality evidence suggests that UAL is associated with reduced surgeon fatigue as well as increased operating times, slower aspiration rates and an increased learning curve. There is inadequate evidence to determine whether the theoretical potential for DNA damage from ultrasound is realized in the clinical setting. CONCLUSIONS: The evidence base for UAL is inadequate to determine the procedure's safety and efficacy. The potential for DNA damage must be investigated with appropriate in vivo animal models. Recommendations for the safe use of UAL are discussed.

Tumescent liposuction in Germany: history and new trends and techniques.

Due to the developments and changes of tumescent solution, infiltration technique, and cannulas, we perform tumescent liposuction today using up to 6-8 l tumescent solution. Total aspirate measures up to 9 l, pure fat aspired up to 5 l. Tumescent liposuction of extended areas can still be done as an outpatient procedure. The condition of patients intra- and postoperatively as well as results has improved and the predictability of outcome is more certain.
