腭裂修复术后软腭形态多样性的研究

Morphological diversity of the soft palate in individuals after palatoplasty

目的通过X线头颅侧位片研究腭裂修复术后腭咽闭合不全(VPI)患者及腭裂修复术后腭咽闭合完全(VPC)患者的软腭形态,为腭裂修复的研究提供参考。方法对腭裂修复术后的113例患者进行分析,观察其软腭在X线头颅侧位定位片上的静态形状特点,并分析术后VPI与术后VPC患者软腭类型分布的差异以及术后VPI患者中不同年龄组和性别组间构成比的差异。结果术后VPI和VPC患者的软腭在X线头颅侧位定位片中表现为6种类型,分别为梭叶型、月牙型、钝角三角型、条带型、粗短型、不规则型;术后VPI与术后VPC患者软腭类型分布的构成有差异;术后VPI患者两年龄组间各类型构成比无差异,两性别组间有差异。结论在数字化头影侧位片中,腭裂修复术后的软腭静态形状呈多样性。

Objective The objective of this study is to investigate, using the lateral cephalometry, the morphological diversity of the soft palate in individuals after palatoplasty including patients with velopharyngeal incompetence（VPI） and those with velopharyngeal competence（VPC）. This study also sheds light on the therapy for cleft palate. Methods As ample comprising 113 in dividuals after palatoplasty was observed in this study. The morphology of the soft palate was observed using lateral cephalometry. Differences in the distribution of morphological types between postoperative VPI and VPC patients were analyzed. Moreover, distribution of morphological types on the basis of age group and gender among the postoperative VPI individuals were also observed. Results The morphology of the soft palate was classified into six types. Significant differences in the distribution of morphological types between postoperative VPI and VPC patients were observed. Among the postoperative VPC individuals, the proportion between male and female is significantly different. However, no significant difference was found in the distribution of morphological types among age groups. Conclusion After palatoplasty, the soft palate exhibited various radiographic appearances as revealed by lateral cephalometry. The classification system and the statistical finding spresented in this report are beneficial to the research on velopharyngeal closure in individuals with cleft palate.
