The purpose of this study is to look at the prevalence of vocal symptoms and acoustic changes in patients with polycystic ovary syndrome (PCOS).
A total of 17 patients with PCOS diagnosed on the basis of three criteria: the presence of irregular menstrual cycles, hirsutism, and polycystic ovaries were included in the study. Twenty-one normal females' frequencies matched on age with the cases were used as controls. The following vocal symptoms were investigated: throat clearing, deepening of the voice, loss of voice, lump in the throat, and difficulty being heard. Acoustic analysis and laryngeal videostroboscopy were performed.
The age range was between 19 and 38 years with a mean age of 26 years. The most common prevailing symptom was throat clearing present in 76.5% versus 4.8% in the controls, followed by loss of voice (47.6%), lump in the throat (41.2%), and deepening of voice (35.3%). The differences in the prevalence of throat clearing, deepening of voice, lump in the throat, and difficulty being heard were statistically significant compared with controls (P value<0.05). There was no statistically significant difference in the acoustic parameters except for an increase in the relative average perturbation (P value=0.035) and a decrease in maximum phonation time (P value=0.001) in patients with PCOS. In the PCOS group, three patients had evidence of mild vocal fold edema and one patient had vocal fold nodules. In the control group, one subject had vocal fold edema and one subject had vocal fold nodules.
Patients with PCOS seem to have more vocal symptoms compared with controls. Physicians should be aware of vocal changes in hirsute subjects with PCOS.
本研究旨在观察多囊卵巢综合征(PCOS)患者的嗓音症状和声学变化的发生率。
共纳入 17 名符合以下三个标准的 PCOS 患者:月经周期不规律、多毛和多囊卵巢。21 名年龄与病例相匹配的正常女性作为对照组。研究了以下嗓音症状:清嗓、声音低沉、声音嘶哑、喉咙有异物感和难以被听到。进行了声学分析和频闪喉镜检查。
年龄范围为 19 岁至 38 岁,平均年龄为 26 岁。最常见的主要症状是清嗓,发生率为 76.5%,而对照组为 4.8%,其次是声音嘶哑(47.6%)、喉咙有异物感(41.2%)和声音低沉(35.3%)。与对照组相比,清嗓、声音低沉、喉咙有异物感和难以被听到的症状发生率差异有统计学意义(P 值均<0.05)。除相对平均扰动增加(P 值=0.035)和最长发声时间减少(P 值=0.001)外,声学参数差异无统计学意义。在 PCOS 组中,3 名患者有轻度声带水肿的证据,1 名患者有声带小结。在对照组中,1 名患者有声带水肿,1 名患者有声带小结。
与对照组相比,PCOS 患者似乎有更多的嗓音症状。医生应该注意到患有 PCOS 的多毛患者的嗓音变化。
