To evaluate vocal symptoms, voice characteristics and videolaryngoscopy in obese women before and after bariatric surgery.
Obese patients (18 to 59 years old), candidates for bariatric surgery were recruited. Evaluation times: T1 (preoperative), T2 (after six months), T3 (after 12 months). Evaluated parameters: weight, height, body mass index, abdominal and neck circumference, vocal self-assessment, perceptual and acoustic vocal assessment, and videolaryngoscopy.
A total of 37 obese women were included, average age 40.8 years. There was a decrease in anthropometric measurements between the preoperative assessment and after 12 months: weight (121.18 ± 15.4 kg; 77.1 ± 11.6 kg), BMI (46.6 ± 6.95 kg/m; 30 ± kg/m), abdominal circumference (128 ± 16.1; 99.1 ± 12.1), and neck circumference (41.1 ± 5.85; 36.6 ± 3.02). Gastroesophageal (21.6%) and vocal symptoms (27%) prevailed. No difference was identified in vocal self-assessment between the evaluations. In the acoustic analysis, f0 increased and the soft phonation index decreased. The perceptual analysis registered lower scores for the degree of dysphonia (G) and voice instability (I). The maximum phonation time values increased without changing the s/z ratio. Videolaryngoscopies showed a posterior middle cleft and improvement in the signs of reflux.
Bariatric surgery led to an important and gradual decrease in anthropometric parameters. The voice became less hoarse, with higher pitch and more stable, with an improvement in maximum phonation time, however with slight breathiness. Such changes were not noticed by the patients.
评估肥胖女性接受减重手术后的嗓音症状、嗓音特征和喉镜检查结果。
招募了年龄在 18 至 59 岁之间、有资格接受减重手术的肥胖患者。评估时间：T1（术前）、T2（术后 6 个月）、T3（术后 12 个月）。评估参数：体重、身高、体重指数、腹围和颈围、嗓音自我评估、感知和声学嗓音评估以及喉镜检查。
共纳入 37 名肥胖女性，平均年龄 40.8 岁。术前评估与术后 12 个月时的人体测量学测量值均下降：体重（121.18±15.4kg；77.1±11.6kg）、BMI（46.6±6.95kg/m；30±kg/m）、腹围（128±16.1cm；99.1±12.1cm）和颈围（41.1±5.85cm；36.6±3.02cm）。胃食管反流（21.6%）和嗓音症状（27%）更为常见。嗓音自我评估在各评估之间无差异。声学分析中，f0 增加，柔和发声指数降低。感知分析中，声扰度（G）和声音不稳定性（I）评分降低。最长发声时间值增加而 s/z 比值不变。喉镜检查显示后中部裂和反流征象改善。
减重手术导致人体测量学参数显著且逐渐下降。嗓音变得不那么嘶哑，音调更高且更稳定，最长发声时间增加，但略有气息声。这些变化患者未察觉。
