Abstract
AIM: This article describes four new methods as the last resort for reconstruction of the nasal floor in difficult-to-repair alveolar cleft patients, including bone suture technique, vascularized interpositional periosteal-connective tissue flap from the palate (VIP-CT flap), anteriorly based inferior turbinate flap, and skinless subcutaneous nasolabial flap, with emphasis on indications and limitations. METHODS: In a retrospective study, data were obtained from 214 patients referred to the Department of Oral and Maxillofacial Surgery, Mashhad Dental School, Iran, for alveolar cleft bone grafting in 2004-2013. Eighteen patients had been treated using special techniques other than direct suturing for reconstruction of the nasal floor during alveolar cleft bone grafting. RESULTS: Eighteen patients had been treated using these techniques as the last resort for nasal floor reconstruction; including bone suture technique (50%), inferior turbinate flap (33.3%), VIP-CT flap (11.2%) and nasolabial flap (5.5%). All the patients had a unilateral alveolar cleft, 72.2% of which were located on the left side and 44.5% of the patients were female. CONCLUSION: Nasal floor reconstruction in 8.4% of alveolar cleft patients needed special techniques and flaps.
