摘要
目的:评价上颌骨缺损赝复体修复的语音康复效果。方法:测量21例上颌骨缺损患者不戴赝复体和戴赝复体1月后的语音清晰度和元音声学特点。结果:患者不戴赝复体时的语音清晰度平均为(23.2±7.4)%,戴赝复体1月后上升至(81.8±9.4)%(P<0.0001),戴赝复体与不戴赝复体相比,元音共振峰频率值有变化,其中发元音/i/时第二共振峰(F2)显著升高。结论:赝复体能明显改善上颌骨缺损患者的语音功能。
Objective：To evaluate speech outcomes following prosthetic obturation of maxillary defects. Methods： The speech intelligibility （SI） of 21 patients with maxillary defects with and without prostheses was measured postoperatively . In addition, the acoustic characteristics of vowels of 21 individuals were analyzed with and without an obturator in place by sound spectrograph. Results ： Following the placement of maxillary obturator prostheses, there was significant improvement in SI. The mean SI score of the patients without and with the prosthesis was （23.2 ± 7.4） % and （81.8 ± 9.4）% respectively（ P 〈 0. 000 1 ）. Conclusion：The obturator prostheses can significantly improve the rehabilitation of speech.
