Patients with morbid obesity may present vocal alterations, since large accumulation of fat in the vocal tract may interfere with voice production of these individuals.
Verify the neck circumference and the acoustic parameters of voice in obese women, before and after the bariatric surgery, and compare the results with a control group, with normal weight.
Observational, longitudinal, descriptive study with patients referred to the SCODE (Obesity Surgery and Related Disorders Center) in a university hospital. The sample consisted of 25 morbidly obese women, age range 28-43 years and 23 non-obese women, aged 21-41 years control group. To measure the neck circumference, a tape measure was used and all participants were seated upright with the head positioned in the Frankfort horizontal plane. The fundamental frequency was calculated through the sustained emission of vowel [a] at usual intensity and pitch, to measure the fundamental frequency of the voice, that is, how much the vocal fold vibrates per second. After the recording, participants were prompted to produce vowels [a], [i], and [u] sustained at usual intensity and pitch, and a stopwatch was used to measure the maximum phonation time, to verify the balance between myoelastic and dynamic forces of the larynx. After 8 months post-surgery, the patients were recruited to be re-evaluated using the same pre-surgical data collection procedures.
There was an increase in the mean value of f0. The maximum phonation time of all vowels increased after surgery.
Obese individuals with post-surgery weight loss may present neck circumference, fundamental frequency, and maximum phonation time values closer to the mean values of normal weight individuals. In this study, weight loss was sufficient to adjust the acoustic parameter measurements.
病态肥胖患者可能会出现嗓音改变，因为声道中大量脂肪堆积可能会干扰这些人的发声。
验证肥胖女性在减重手术前后的颈围和嗓音声学参数，并将结果与体重正常的对照组进行比较。
对一家大学医院SCODE（肥胖手术及相关疾病中心）转诊的患者进行观察性、纵向、描述性研究。样本包括25名年龄在28 - 43岁的病态肥胖女性和23名年龄在21 - 41岁的非肥胖女性作为对照组。使用卷尺测量颈围，所有参与者均直立就座，头部位于法兰克福水平面。通过在通常强度和音高下发元音[a]的持续发声来计算基频，以测量嗓音的基频，即声带每秒振动的次数。录音后，促使参与者在通常强度和音高下持续发出元音[a]、[i]和[u]，并使用秒表测量最长发声时间，以验证喉肌弹性和动力之间的平衡。术后8个月，招募患者使用与术前相同的数据收集程序进行重新评估。
f0的平均值增加。术后所有元音的最长发声时间均增加。
术后体重减轻的肥胖个体的颈围、基频和最长发声时间值可能更接近体重正常个体的平均值。在本研究中，体重减轻足以调整声学参数测量结果。
