Abstract

Background: Facial lipoatrophy is one of the most distressing manifestation for HIV patients. It can be stigmatizing, severely affecting quality of life and self-esteem, and it may result in reduced antiretroviral adherence. Several filling techniques have been proposed in facial wasting restoration, with different outcomes. The aim of this study is to present a triangular area that is useful to fill in facial wasting rehabilitation.
Methods: Twenty-eight HIV patients rehabilitated for facial wasting were enrolled in this study. Sixteen were rehabilitated with a non- resorbable filler and twelve with structural fat graft harvested from lipohypertrophied areas. A photographic pre-operative and post- operative evaluation was performed by the patients and by two plastic surgeons who were “blinded.” The filled area, in both patients rehabilitated with structural fat grafts or non-resorbable filler, was a triangular area of depression identified between the nasolabial fold, the malar arch, and the line that connects these two anatomical landmarks.
Results: The cosmetic result was evaluated after three months after the last filling procedure in the non-resorbable filler group and after three months post-surgery in the structural fat graft group. The mean patient satisfaction score was 8.7 as assessed with a visual analogue scale. The mean score for blinded evaluators was 7.6.
Conclusion: In this study the authors describe a triangular area of the face, between the nasolabial fold, the malar arch, and the line that connects these two anatomical landmarks, where a good aesthetic facial restoration in HIV patients with facial wasting may be achieved regardless of which filling technique is used.

INTRODUCTION

The use of highly active retroviral therapy (HAART) with protease inhibitors, first introduced in the United States in 1997, has demonstrated a significant clinical benefit in the treatment of HIV infection.1,2 Within one year of its introduc- tion, mortality rates dropped by 45%, and there was a signifi- cant decline in the number of reported AIDS-defining diseases. But, as the most part of chronic pharmacologic therapies, there are several side effects such as: diarrhea, renal calculi, nausea, and perioral paresthesias.3
One medication-associated condition that has become prevalent among HIV-infected patients is HIV-associated lipodystrophy, a syndrome characterized by abnormal fat metabolism and deposition.4 Broadly speaking the lipodystrophy syndrome is composed of three components5: 1.) Lipoatrophy (subcutane- ous fat loss in the face, limbs, and buttocks) 2.) Lipohypertrophy (fat accumulation in the abdomen, and dorso-cervical fat pad) 3.) Metabolic disturbance (insulin resistance, hypercholesterol- emia, and hypertriglyceridemia6).
Despite the initial reports of an association between protease in- hibitors and lipodystrophy, it soon became apparent that other drugs were implicated.7 In 1999, an association between thymi- dine analogues, particularly d4T, and fat wasting was reported,8 supported by improvements in subcutaneous fat and serum triglyceride levels after switching d4T to zidovudine (AZT) or aba- cavir (ABC).9 Over the course of time it has been realized that the components of lipodystrophy syndrome are, at least partially, in- dependent processes,10,11 different antiretrovirals are associated with different types and degrees of toxicity,12,13 and lipodystro- phy syndrome is the result of a complex interaction between a variety of factors.14 In general thymidine analogues, especially d4T, are associated with lipoatrophy and protease inhibitors with lipohypertrophy and dyslipidaemia.15
