Bimaxillary orthognathic double chin surgery is performed for therapeutic purposes in patients with occlusion disorders due to dentofacial deformity. We aimed to show the effect of this procedure on sound acoustics.
The study was planned as retrospective and cross-sectional. Information about patients who applied to our center due to developmental malocclusion between 2018 and 2020 was examined. A total of 26 patients, 13 males and 13 females, who underwent orthognathic double jaw surgery after orthodontic treatment, were included in the study. Vowel (/a/,/e/,/i/,/ı/,/o/,/ö/,/u/,/ü/) recordings of the patients were analyzed before the surgery and at the 6th month after the surgery. Sound recordings were taken with the Audacity program (Open Source Software). The recordings were analyzed with the Praat acoustic analysis program. Before and after surgery for each letter; Fundamental frequency, Shimmer, Jitter and Harmony Noise Ratios were examined. Measurements taken before and after surgery were compared.
A decrease in fundamental frequency, jitter, shimmer and harmony noise values was detected. This can be interpreted as an increase in sound quality. A statistically significant change was detected in at least two parameters for each letter.
Orthognathic double chin surgery performed due to dentofacial deformity provides an increase in the pronunciation of vowels and voice quality. To increase the reliability of the result, acoustic analysis was performed with multiple parameters.
双颌正颌去双下巴手术用于治疗因牙颌面畸形导致咬合紊乱的患者。我们旨在展示该手术对语音声学的影响。
本研究计划为回顾性横断面研究。对2018年至2020年间因发育性错牙合畸形前来本中心就诊的患者信息进行了检查。共有26例患者（13例男性和13例女性）纳入研究，这些患者在正畸治疗后接受了正颌双颌手术。在手术前和手术后第6个月对患者的元音（/a/、/e/、/i/、/ı/、/o/、/ö/、/u/、/ü/）录音进行分析。使用Audacity程序（开源软件）进行录音。使用Praat声学分析程序对录音进行分析。对每个字母在手术前后检查其基频、微扰、抖动和和谐噪声比。比较手术前后的测量结果。
检测到基频、抖动、微扰和和谐噪声值降低。这可解释为语音质量提高。每个字母至少有两个参数检测到有统计学意义的变化。
因牙颌面畸形进行的正颌去双下巴手术可提高元音发音和语音质量。为提高结果的可靠性，使用多个参数进行了声学分析。
