The study reviews oronasal fistulae occurring after palatoplasty. Subjects were fifty-two patients who had received palatoplasty in our clinic from 1981 to 1987. In twenty-one cases (40%) oronasal fistulae persisted. Two-thirds of these fistulae were slits or pinholes. The ratio of fistula occurrence was relatively high compared to other reports. Most of them were observed at the junction of the premaxilla and maxilla. There was no significant difference between fistula formation and the distance of the push back, and also there was no correlation with the width of the cleft.
本研究回顾了腭裂修复术后出现的口鼻瘘。研究对象为1981年至1987年在我院接受腭裂修复术的52例患者。21例（40%）患者口鼻瘘持续存在。其中三分之二的瘘为裂隙或小孔。与其他报道相比，瘘的发生率相对较高。大多数瘘位于前颌骨与上颌骨的交界处。瘘的形成与后推距离之间无显著差异，且与腭裂宽度也无相关性。
