Background and objective: Large defects of the nose after Mohs surgery pose a significant reconstructive challenge to both dermatologic and reconstructive surgeons. The authors present their 12-year experience utilizing acellular dermal matrices for nasal reconstruction.
Methods: A retrospective review of patients undergoing Mohs surgery and alloplastic nasal reconstruction with acellular dermal matrices between 2010 and 2022 was performed. Patients who underwent single-stage reconstruction and dual-stage reconstruction with skin graft with at least 90 days of follow-up were included.
Results: Fifty-one patients met criteria with a median age of 77 years. Fifty-three lesions were reconstructed with acellular dermal matrices. The most common lesion location was nasal sidewall (50%) with a mean defect size of 10.8 cm 2 . 30.8% underwent same-day acellular dermal matrix reconstruction, with 69.2% undergoing two-stage reconstruction. Acellular dermal matrices successfully reconstructed acquired defects in 94.2% of lesions. Average time to re-epithelialization was 27.6 + 6.2 days. Average time to repigmentation was 145.35 + 86 days. No recurrences were recorded. Total complication rate was 9.62%. Average size for successful healing was 10.8 cm 2 . Average defect size for complication or failure was 14.7 cm 2 . Seven sites (13.46%) underwent aesthetic improvement procedures.
Conclusion: Acellular bilayer wound matrix is an adequate reconstructive option for single or dual-stage reconstruction of the nose with low complication and revision rates.
