The main technique for repair of septal perforations at our institution is an uncommon one. It relies on mobilization of a pedicled mucosal flap from the oral cavity.1,2 This labial-buccal sulcus (LBS) technique is mentioned rarely in the septal perforation literature and usually to caution against its use. Unacceptable nasal dryness and “considerable donor site morbidity,” including oronasal fistula and the risk for complete flap loss, have been attributed to the technique.3- 5
