This investigation was undertaken to determine the effects of orthognathic surgery on speech. Forty adult females were studied preoperatively and either 6 or 12 months postoperatively. Three experienced speech and language pathologists performed narrow phonetic transcriptions of tape-recorded words and sentences produced by each of the forty patients. These judges also recorded their ratings of each patient's overall hypernasality, hyponasality, and articulation proficiency. In addition, objective assessments of velopharyngeal port area, nasal-oral acoustic coupling, and nasal resistance were obtained. The results suggest that nasal-oral acoustic coupling and nasal resistance are the only parameters significantly affected by orthognathic surgery.
本研究旨在确定正颌手术对言语的影响。对40名成年女性进行了术前及术后6个月或12个月的研究。三名经验丰富的言语和语言病理学家对这40名患者每人录制的单词和句子进行了精细的语音转录。这些评判者还记录了他们对每位患者整体高鼻音、低鼻音和发音熟练度的评分。此外，还获得了腭咽口面积、鼻口声学耦合和鼻阻力的客观评估结果。结果表明，鼻口声学耦合和鼻阻力是仅受正颌手术显著影响的参数。
