二次咽成形术对腭裂患者辅音清晰度的影响

Effect of secondary pharyngoplasty in consonant articulation of cleft palate patients

本文通过对30例因腭咽闭合不全而行二次咽成形术的患者进行语音评价,分析了手术前后辅音清晰度的变化,结果发现咽成形术后各辅音清晰度均有显著改善,尤以爆破音最为明显,其后依次为塞擦音、摩擦音及鼻辅音。作者认为腭咽闭合不全对爆破音发音有直接影响,而擦音的发音异常则主要与不良语音习惯有关。

This paper reported studies of speech evaluation in 30 patients who had undergone secondary pharyngoplasty because of velopharyngeal incompetence. The articulation of consonants was analyzed before and after operation. The results showed that there was significant improvenent in the consonant articulation after the secondary pharyngoplasty, particularly in thc production of plosive sound, followed by affricative, fricative and nasal consonants, This result illustrated that the plosive sound was directly influenced by velopharyngoal incompctence, and the fricative sound was mainly affected by the improper habit in pronounciation.
