上颌骨Le FortⅠ型截骨前徙术对唇腭裂患者腭咽结构及功能影响的临床探讨
Clinical study of the effect on the velopharyngeal structure and function of maxillary hypoplasia patients of cleft lip and palate after Le FortⅠosteotomy for maxillary advancement
摘要
Abstract
Objective:To study the effect on the velopharyngeal function of maxillary hypoplasia patients of cleft lip and palate after Le FortⅠ osteotomy for maxillary advancement. Methods:Fifteen patients with maxillary hypoplasia of cleft lip and palate underwent Le FortⅠ osteotomy. Cephalometric analysis was obtained from all patients at centric occlusion and during phonating. The larynx dynamic strobolaryngoscope video recording check, the test of blowing and the evaluation of speech were carried out to compare the changes of velopharyngeal function before and after operation. Results:The average maxillary advancement was (4.28 ±2.02) mm. The depth of pharyngeal cavity increased significantly after operation(P<0.05). The length of the soft palate and the angle between soft and hard palate increased obviously than preoperative (P<0.05 ) . And the thickness of the soft palate were reduced. Conclusion:Correction of maxillary hypoplasia by using Le FortⅠosteotomy for maxillary advancement will increase the velopharyngeal cavity depth,which may impair velopharyngeal competence. But the compensatory effects of velopharyngeal soft tissue may alleviate this impairment to some extent.关键词
