Large oroantral fistula repair using combined buccal and palatal flaps: a case series

Abstract

AimThe aim was to detect the efficacy of combined buccal advancement and palatal rotational flaps in closure of large oroantral fistulas (OAFs) after dental extraction.Materials and methodsA 3-year prospective study was conducted between February 2014 and May 2017. A total of 11 patients with large OAF after dental extraction were included in the study. Seven patients developed OAF after dental extraction of the maxillary first molar teeth, whereas two patients developed an OAF after dental extraction of the second maxillary premolars. The last two patients developed an OAF after dental extraction of the second maxillary molars.ResultsClosure of the defect was achieved in 10 cases, whereas only one case had failure. In addition to postoperative pain, swelling, and reduction of the vestibular sulcus, one patient experienced postoperative nasal adhesions between the nasal septum and inferior turbinate.ConclusionA combined buccal and palatal flap is efficient in closure of large delayed OAF secondary to dental extraction. Further study is required to assess new bone formation after repair of large OAF using this technique.
