Progressive hemifacial atrophy is a disease in which the soft and hard tissues of the unilateral trigeminal nerve domain progressively degenerate. We describe our experience with a patient with unilateral lip atrophy due to progressive hemifacial atrophy who underwent unilateral reconstruction of the upper lip. The patient was a 22-year-old woman. She had difficulty closing her mouth due to the unilateral lip atrophy. We performed reconstruction of the upper lip on the atrophic side with a cross-lip vermilion flap of the non-atrophic lower lip and released the flap 14 days postoperatively. Viability of the flap was favorable postoperatively. Slight drooping of the upper lip on the affected side gradually developed after the operation. Subsequently, we performed minor correction of the upper lip on the affected side 5 months postoperatively. Atrophy and deformity of the upper lip on the affected side were not evident, and the form of the lip and function of lip closure on the affected side were satisfactory 2 years postoperatively. To correct the form and function in the presence of upper lip atrophy, the use of a cross-lip vermilion flap of the non-atrophic lower lip could become a useful technique for reconstruction.
