To present the epidemiology and correlation with perceptual analysis of vocal nodules in pediatric patients.
Retrospective review of patients seen in a tertiary care pediatric hospital's voice center from 1996 to 2003. Six hundred and forty-six patients were evaluated with videostroboscopic examinations and perceptual analysis of voice characteristics by speech pathologists. Appropriate treatment was based on the pathology identified.
Two hundred and fifty-four patients (40%) with an average age of 7.7 years (range 0.1-19.3 years) were identified as having vocal nodules. Of these, 72% were male. Six patients (2%) were under the age of 7 months. Nodules were most commonly found in males, aged 3-10 years old. Evidence of gastro-esophageal reflux disease was found in one-quarter of patients; hyperfunction of the larynx was seen in three-fourths. Hyperfunction of the larynx correlates with the size of vocal nodules. Distortion of the vocal fold mucosal wave was not present. Perceptual analysis revealed positive correlation of the severity of hoarseness, breathiness, straining and aphonia with the size of vocal nodules.
The epidemiology and correlation with perceptual voice analysis in pediatric patients with vocal nodules is presented. Hyperfunction of the larynx correlates with nodule size, while the presence of reflux disease does not. The severity of hoarseness, breathiness, straining and aphonia correlates with the size of vocal nodules.
介绍小儿声带小结的流行病学情况及其与嗓音感知分析的相关性。
对1996年至2003年在一家三级儿科医院嗓音中心就诊的患者进行回顾性研究。646例患者接受了频闪喉镜检查，并由言语病理学家对嗓音特征进行了感知分析。根据所确定的病理情况进行适当治疗。
254例患者（40%）被确诊为声带小结，平均年龄7.7岁（范围0.1 - 19.3岁）。其中，72%为男性。6例（2%）年龄在7个月以下。小结最常见于3至10岁的男性。四分之一的患者有胃食管反流病的证据；四分之三的患者存在喉功能亢进。喉功能亢进与声带小结的大小相关。声带黏膜波无扭曲。感知分析显示，声音嘶哑、气息声、用力发声和失音的严重程度与声带小结的大小呈正相关。
本文介绍了小儿声带小结的流行病学情况及其与嗓音感知分析的相关性。喉功能亢进与小结大小相关，而反流病的存在与之无关。声音嘶哑、气息声、用力发声和失音的严重程度与声带小结的大小相关。
