半舌缺损患者前臂皮瓣修复后舌尖辅音及元音的语音评价

Evaluation of the tip tongue consonants and vowels in the hemi-tongue defect patients after reconstruction with forearm flap

目的探讨舌癌根治同期前臂皮瓣修复对半舌缺损患者术后舌尖辅音及元音的恢复效果。方法20例舌癌患者接受半侧舌体切除同期前臂皮瓣修复术,手术治疗6个月后,分析前臂皮瓣修复患者舌尖辅音及元音的语音特点。VS-9700语音工作站对患者术前及手术6个月后的元音进行语音频谱分析。结果(1)前臂皮瓣修复患者舌尖辅音中/sh/、/zh/清晰度欠佳,元音恢复效果良好。(2)前臂皮瓣修复组患者元音中仅/i/的第一共振峰值低于对照组,两组之间差异有统计学意义(P<0.05)、而/i/的第二共振峰值与对照组差异无统计学意义(P>0.05)。结论前臂皮瓣修复可以改善半舌缺损患者术后语音功能。

Objective To explore the effect of the tip tongue consonants and vowels in the hemi-tongue defect patients after reconstruction with forearm flap （FAF）. Methods 20 patients who underwent hemiglossectomy were reconstructed with FAP flaps. After 6 months, the patients＇ consonants and vowels were evaluated by articulation test. VS-9700 was used to analyze the speech character of vowels before and after operation. Results （ 1 ）The speech articulation of/sh/,/zh/ in all tip tongue consonants were bad in patients who underwent hemi-tongue reconstruction with FAF. The vowels were good. （2）Only the first formant （F1） of/i/ of the FAF group was lower than that of the control group （P 〈 0.05）, but there was no significant differences between FAF group and control group in F2 of/i/ （P 〉 0.05）. Conclusion Articulator function can be well achieved by forearm flaps reconstruction in hemi-tongue defect patients.
