摘要: [摘要] 目的 探讨骨性Ⅲ类错牙合畸形患者正颌手术对其语音功能的影响。方法 经南京医科大学附属口腔医院正畸-正颌联合矫治中心诊断为上颌发育不足为主的骨性Ⅲ类错合患者26名,根据病史及专科检查分为两组:唇腭裂组(A组)10例,为先天性唇腭裂患者术后继发上颌骨发育不足;非唇腭裂组(B组)16例,均为单纯发育性骨性Ⅲ类错牙合畸形。所有患者分别于术前、术后1月采集语音信息,对语音清晰度和6个元音(/a/、/o/、/e/、/i/、/u/、/ü/)的前三个共振峰频率进行差异性统计分析。结果 A组患者语音清晰度、/i/F1、/i/F2、/o/F2、/u/F2手术前后也发生了较为明显的变化,差异有统计学意义(P <0.05),其中语音清晰度的下降程度与上颌骨块前移的距离呈较好的相关性(r=0.8125);B组患者手术前后语音清晰度及各元音共振峰频率改变不明显,差异无统计学意义。结论 正颌手术会加重唇腭裂继发骨性Ⅲ类错牙合畸形患者腭咽闭合功能不全的程度,语音功能进一步恶化。单纯发育性畸形患者代偿性好,影响不明显。

Abstract: Abstract: Objective To explore effects of the orthognathic surgery treating class Ⅲ osseous maxillofacial deformities on the patients′ voice function.Methods A total of 26 consecutive cases,who were diagnosed as class Ⅲ osseous maxillofacial deformities by orthodonticorthognathic associated therapy center of the affiliated stomatological hospital of Nanjing Medical University,were enrolled in this study.Those cases were divided into two groups according to the medical history and specialized examination.The cleft lip and palate group (Group A)included 10 cases.They were all congenital cleft lip and palate patients with secondary maxillary dysplasia.The other 16 cases diagnosed as developmental malformation alone were named none cleft lip and palate group (Group B).The voice information was collected before and one month after the surgery respectively.The statistic differences in voice intelligibility and first three formant frequencies of 6 vowels (/a/,/o/,/e/,/i/,/u/,/ü/) were analyzed.Results Group A,the voice intelligibility,the first and second formants of vowel /i/,and the second formant of /o/ and /u/ changed significantly(P <0.05);the decline degree of voice intelligibility was positively correlated with antedisplacement distance(r=0.8125).In Group B,the changes of voice intelligibility and every vowel′s formant were not significant after operation.Conclusions Orthognathic surgery treating class Ⅲ osseous maxillofacial deformities may exacerbate the degree of velopharyngeal incompetence for patients with secondary maxillary dysplasia,worsening their voice function.However,the surgery could be a compensation for the developmental malformation patients,delivering no significant impact.
