Free anterolateral thigh adipofascial flap for hemifacial atrophy.

Though the etiology of hemifacial atrophy is still unknown, the aim of its reconstruction is cosmetic amelioration of the defect. Among many techniques introduced, microsurgical reconstruction has become the gold standard to restore the symmetry of the face. Seven free anterolateral thigh adipofascial flaps were used to reconstruct hemifacial atrophy between September 1999 and May 2005. There were 1 male and 6 females in the series. All the patients had unilateral disease (6 right and 1 left). The average age of onset of disease was 11.9 years. The average duration of atrophy was 6.7 years. The patients' average age was 25 years (range, 21 to 32 years), and the average follow-up period was 12.6 months (range, 6 to 36). The size of the transferred flap ranged from 8 x 6 cm to 12 x 13 cm. All adipofascial flaps survived completely. No complications occurred. The result is stable, and no recurrence of facial atrophy was seen in the patients after follow-up. One patient received minor revision because of the bulky reconstructed face. The esthetic appearance of the reconstructed face was acceptable. Despite a variable vascular anatomy that can give rise to some surgical challenge in raising the anterolateral thigh adipofascial flap, the authors conclude that this is a safe and reliable adipofascial flap for hemifacial atrophy.
