腭裂咽成形术后患者语音治疗疗效评价

目的:对腭咽成形术后存在语音障碍的患者进行语音治疗,通过治疗前后语音清晰度比较,评价该方法的疗效。方法:咽成形术后患者82例,年龄4~31岁。采用汉语语音清晰度测试表对患者进行治疗前后语音清晰度检测,根据代偿性发音特点进行系统化语音训练:①腭咽闭合功能锻炼;②音素→音节→词组→短句→短文、会话。训练时按发音部位由前→后,按发音方法由易→难、送气音→不送气音、塞音→擦音→塞擦音。训练周期1.5~12个月,平均3.83个月。结果:以腭咽闭合不全型为特点的代偿性语音患者共71例;其中声门塞音患者语音清晰度由治疗前的46.27%提高到治疗后的97.16%;咽摩擦音患者由治疗前的57.19%提高到治疗后的97.72%。以腭咽闭合良好型为特点的代偿性语音共11例,腭化、侧化音患者语音清晰度由治疗前的71.10%提高到治疗后的98.55%;3组经t检验,P均<0.001,具有极显著性差异。结论:对咽成形术后腭咽闭合不全型的代偿性发音,首先加强腭咽闭合功能,再建立正确的发音部位和方法;对咽成形术后腭咽闭合良好型的代偿性发音,可直接建立正确的发音部位和方法。

An evaluation of the speech therapy methods for patients after pharyngoplasty

PURPOSE: Speech therapy was carried out for patients with speech disorders after pharyngoplasty, and the comparison of speech articulation before and after treatment, was done to evaluate the new method. METHODS: 82 patients with the varying age from 4 to 31 years were included in the current study. The patients' speeches including syllables, word, phrase and sentence were compared before and after treatment according to Chinese Speech Intelligibility Testing Form. The systematic speech training was carried out according to the compensatory articulation characteristics. The steps were as follows. Firstly, the function of velopharyngeal closure should be strengthened. Secondly, the patients were trained with an average duration of 3.83 months (range from 1.5-12 months) according to the following three sequences: One was from phoneme, syllables, phrase, sentence to short paragraph or dialogue, another was from anterior to posterior according to the speech position, and the other was from easy to difficult according to the articulation method, such as from aspirated syllables to non-aspirated syllables, from plosive, fricative to affricative. RESULTS: There were 71 patients with compensatory articulation characteristic of velopharyngeal incompetence, the speech articulation of patients with glottis plosive increased from preoperative 46.27% to postoperative 97.16% (P<0.001). The speech articulation of patients with pharynx fricative increased from preoperative 57.19% to postoperative 97.72% (P<0.001). There were 11 patients with compensatory articulation characteristic of velopharyngeal adequacy, and the speech articulation of 11 patients with palatalized and lateral misarticulation increased from preoperative 71.10% to postoperative 98.55% (P<0.001). CONCLUSIONS: The training of velopharyngeal closure should be emphasized on the patients with compensatory articulation resulting from velopharyngeal incompetence after pharyngoplasty, then the correct speech position and method was established. While to the patients with compensatory articulation without velopharyngeal incompetence after pharyngoplasty, the correct speech position and method could be directly established.
