Excisional lipectomy for HIV-associated cervicodorsal lipodystrophy

Abstract

The development of effective antiretroviral therapy for the treatment of human immunodeficiency virus (HIV) has allowed for prolonged and healthier lives for affected patients. However, significant side effects from the drugs have been well documented, including syndromes of abnormal fat distribution. Cervicodorsal lipodystrophy, or "buffalo hump" deformity, is a common presentation of lipodystrophy syndrome and can cause significant disfigurement to the patient. Surgical correction has been the mainstay of treatment. The authors report on the use of excisional lipectomy to correct cervicodorsal lipodystrophy. Six male patients and one female patient (mean age, 47.2 years) underwent excisional lipectomy for buffalo hump deformity caused by HIV protease inhibitor use. Common complaints on presentation included disfigurement, neck pain, and difficulty sleeping. Deformity had first been observed an average of 4.75 years before presentation (range 2 to 7 years). At the time of consultation all patients were on antiretroviral regimens that included protease inhibitors. Excisional lipectomy of the hypertrophied cervicodorsal fat pad was performed on all patients, with suction-assisted lipoplasty (SAL) additionally to optimally contour the nondystrophic fat at the periphery of the resection. One patient also underwent simultaneous abdominoplasty, another underwent rhytidectomy with autologous fat transfer, and one patient received malar autologous fat injections. The average operative time for all procedures was 2.7 hours (range 1.0 to 5.8 hours). Complications included seroma in three cases and wound dehiscence in one patient, none of which required reoperation. At an average of 26.6 months of follow-up, all patients report satisfaction with their results, and there have been no recurrences. Cervicodorsal lipodystrophy is a well-described complication of extended use of HIV protease inhibitor therapy. Patients may seek consultation with plastic and reconstructive surgeons for correction of the aesthetic and functional morbidity associated with the deformity. Because of the fibrous nature of the hypertrophied cervicodorsal fat and the high rate of recurrence after SAL alone, an approach with excisional lipectomy (with or without SAL) may provide improved results and superior long-term outcomes.
