BACKGROUND Single-stage repairs of large nasal dorsum defects risk introducing lower nasal distortion.

OBJECTIVE To describe the authors experience with the “birhombic” flap, a bilateral Dufourmentel rhomboid flap, for repair of nasal surgical defects after Mohs micrographic surgery.

MATERIALS AND METHODS The authors performed a retrospective chart review of patients who underwent birhombic flap repair of the nose by a single physician after Mohs micrographic surgery from 2008 to 2013 at the Medical University of South Carolina.

RESULTS Thirty-eight patients were identified on whom the birhombic flap repair was performed on the nasal dorsum over a 6-year period. There were no significant complications. Alar position remained neutral and nasal profile remained unaltered in all cases. Postoperatively, pulsed dye laser was performed in 8 patients (21%) and dermabrasion in 11 patients (29%). All patients achieved very good or excellent final aesthetic results.

CONCLUSION The birhombic flap is a reproducible, one-stage flap for small to large defects of the nasal dorsum that consistently produces topographic restoration with minimal risk of aesthetic or functional complication. The use of 2 opposing flaps redistributes the secondary defect, thus minimizing the potential for lower nasal distortion when closing the flaps' donor sites.
