本文的目的是评价一组腭裂患者行上颌骨前移术前和术后一年的腭咽孔大小。观察上颌骨前移量与腭咽孔大小改变之间的关系,软咽长度/咽深度比值预测术后腭咽功能的合理性。材料和方法对24例做过腭裂修补术的患者行上颌前移手术,随访至少一年。其中男性15例,女性9例。年龄14～32岁,平均17.1岁。4例为双侧完全性腭裂,20例为单侧完全性腭裂。单侧裂者行Le Fort-l downfracture手术,双侧裂者行蒂在前的截骨术。全上颌骨前移后的缺隙用自体骨移植。腭咽孔大小采用Warren和Dubois(1964)法测量。用两根咽鼓管
The purpose of this paper is to evaluate the palatopharyngeal orifice size in a group of cleft palate patients before and one year after maxillary advancement. Observe the relationship between the maxillary displacement and the size of the palatopharyngeal hole and the rationality of the soft pharyngeal length / pharyngeal depth ratio to predict the postoperative velopharyngeal function. MATERIALS AND METHODS Twenty-four patients with cleft palate repair underwent maxillary advancement for at least one year. Including 15 males and 9 females. Aged 14 to 32 years old, with an average of 17.1 years old. 4 cases of bilateral complete cleft palate, 20 cases of unilateral cleft palate. Le Fort-l downfracture surgery, single bifurcation line pedicled anterior osteotomy. Whole maxillary advancement of the gap with autologous bone graft. The size of the palatopharyngeal orifice was measured by Warren and Dubois (1964). Eustachian tube with two
