OBJECTIVE
To determine the effect of vocal nodule size on voice in pediatric patients.
STUDY DESIGN
Vocal nodules were graded according to a validated grading scale by three pediatric otolaryngologists.
SUBJECTS AND METHODS
Patients evaluated from 2003 to 2007 with a diagnosis of vocal nodules were included.
RESULTS
Forty patients (21 female) with a mean age of 7.5 years were identified. Vocal nodules were rated as grade 1 (17 patients), grade 2 (15 patients), and grade 3 (8 patients). Pitch range was reduced in patients with larger nodules (P = 0.001). There was no statistical association between nodule grade and fundamental frequency abnormality, perturbation, shimmer, decreased respiratory support, air loss, or significant muscle tension.
CONCLUSIONS
Voice characteristics in patients with vocal nodules were evaluated. Other than pitch reduction, objective and subjective voice measurements are not statistically different in varying vocal nodule sizes; however, many of the measures did show a trend towards significance. Vocal rehabilitation is complex in children with nodules and may not directly correlate with vocal nodule size.
目的
确定小儿患者声带小结大小对嗓音的影响。
研究设计
由三位小儿耳鼻喉科医生根据有效分级量表对声带小结进行分级。
研究对象与方法
纳入2003年至2007年间诊断为声带小结的评估患者。
结果
共确定40例患者（21例女性），平均年龄7.5岁。声带小结被评为1级（17例患者）、2级（15例患者）和3级（8例患者）。小结较大的患者音高范围减小（P = 0.001）。小结分级与基频异常、微扰、声门音波颤动、呼吸支持减弱、漏气或明显肌肉紧张之间无统计学关联。
结论
对声带小结患者的嗓音特征进行了评估。除音高降低外，不同大小声带小结的客观和主观嗓音测量在统计学上并无差异；然而，许多测量结果确实显示出有显著意义的趋势。声带小结患儿的嗓音康复较为复杂，可能与声带小结大小无直接关联。
