Speech characteristics of 20 patients who underwent orthognathic surgery for correction of various skeletal defects were studied before surgical treatment and at periodic intervals postoperatively. Patients completed questionnaires that focused on their perceptions of appearance and oral function after orthognathic surgery. Approximately 60% of the patients demonstrated preoperative articulation errors. These were classified as mild because they did not interfere with the ability to be understood. Periodic testing indicated positive changes in articulation for a majority of those who had exhibited preoperative errors. None of the subjects experienced postoperative deterioration in their articulation. The subjects' perceptions of their individual operations were positive on all variables assessed.
对20名接受正颌手术以矫正各种骨骼缺陷的患者的言语特征在手术治疗前及术后定期进行了研究。患者完成了侧重于他们对正颌手术后外观和口腔功能认知的问卷。约60%的患者术前存在发音错误。这些错误被归类为轻度，因为它们不影响被理解的能力。定期测试表明，大多数术前有错误的患者在发音方面有积极变化。所有受试者术后发音均未恶化。受试者对其各自手术在所有评估变量上的认知都是积极的。
