摘要
目的:对单侧上颌骨缺失患者赝复体修复前后的语音及修复效果进行评价。方法:单侧上颌骨缺失患者15例,给予设计中空式基托的上颌阻塞器赝复体修复,练习被检敏感音/a/、/o/、/e/、/i/、/u/后,分别在初戴前和初戴后输入CSL4400,均测量第1、2、3共振峰(Formart)的平均值。使用SPSS11.0对资料行配对t检验。结果:初戴赝复体前后被检敏感音之间的差异主要集中在F2和F3上(P<0.05),初戴后较初戴前F3有显著性上升。结论:初戴后修复体重建软腭,有效地封闭了口鼻通道,形成近似正常的口腔环境。除F1外,初戴后几乎所有元音的F2、F3均发生改变。单侧上颌骨缺失患者赝复体修复,能显著提高语音效果。
PURPOSE： Evaluation of the outcomes in 15 patients with unilateral maxillary defect befor and after maxillofacial obturator prosthesis. METHODS： 15 patients with unilateral maxillary defect were included in this study, who received obturator prosthesis for maxillary rehabilitation. The pronunciation of the examined phonetics such as/a/,/o/, /e/,/i/,/u/were transferred into CSL400 before and after treatment. The mean value of the first, second, third formant were measured. Paired t test of SPSS11.0 was used for statistical analysis. RESULTS： There was statistically significant difference on F2 and F3 before and after treatment （P〈0.05）. After treatment the value of F3 was increased significantly. CONCLUSIONS： The soft palate was reconstructed after obturator treatment. The space between the nasal and oral cavity was sealed,through which a similar normal oral cavity was obtained. Except F1, F2 and F3 of all the vowels changed after treatment.Maxillofacial prosthesis can improve the speech function of patients with unilateral maxillary defect effectively.
