Reconstruction of the dorsal and sidewall defects

Defects of the nasal dorsum or sidewall can result from trauma, congenital lesions, extirpation of neoplasms, or iatrogenic injuries. Simple techniques are often used to reconstruct defects in this area with excellent outcomes. Complex defects require more sophisticated techniques including multilayer closures using pedicled flaps or free tissue transfer. This review discusses key anatomic and functional principles and techniques to assist in planning for reconstruction of nasal dorsum and sidewall defects from any cause.
