Palatal fistulation is a common complication after cleft palate repair, it could occur at any site along the line of cleft closure. Many techniques have been proposed for its repair. However, the incidence of recurrence after initial fistula closure is high. The aim of this study is to evaluate the efficacy of closure of posterior palatal fistula using buccal myomucosal flap.
Fifteen cases with posterior palatal fistulas - after cleft palate repair - were included in this study. Their fistulas were closed in two-layers; an oral mucoperiosteum hinge flap to reconstruct the nasal side and a buccal myomucosal flap from the inner surface of the cheek to reconstruct the oral side. Follow-up was carried out for 1 year.
The fistulas were completely closed in all cases (100%) with no failure or recurrence. This was a single-stage operation in all cases, with no need for further procedure to divide the pedicle of the flap.
Closure of posterior palatal fistula using buccal myomucosal flap in addition to mucoperiosteal flap is a useful method with high success rate and no morbidity.
腭瘘是腭裂修复术后常见的并发症，可发生于腭裂关闭线沿线的任何部位。已经提出了许多修复方法。然而，初次瘘管闭合后复发的发生率很高。本研究的目的是评估使用颊肌黏膜瓣关闭腭后瘘的疗效。
本研究纳入15例腭裂修复术后腭后瘘患者。瘘管分两层关闭；用口腔黏骨膜铰链瓣重建鼻腔侧，用颊部内表面的颊肌黏膜瓣重建口腔侧。随访1年。
所有病例（100%）的瘘管均完全闭合，无失败或复发。所有病例均为一期手术，无需进一步手术切断瓣蒂。
除黏骨膜瓣外，使用颊肌黏膜瓣关闭腭后瘘是一种成功率高且无并发症的有效方法。
