【摘要】：目的探讨扁桃体肥大患者扁桃体切除手术前后发声的共鸣特征变化。方法使用多通道语音分析系统测试38例8~20岁男性扁桃体肥大患者(扁桃体肥大组,II度大25例,III度大13例)扁桃体切除术前、术后一个月及40例7~22岁正常男性(正常对照组)发/a:/音时头腔、口腔、喉腔、胸腔共鸣频谱特征,分别统计0~999Hz(FR1)、1 000~1 999Hz(FR2)、2 000~2 999Hz(FR3)、3 000~4 000Hz(FR4)频段的能量分布。结果扁桃体肥大组术后一个月,头腔和口腔FR2、FR3能量值、胸腔FR2能量值较术前提高(P0.05),与正常对照组差异无统计学意义(P0.05),头腔、口腔、胸腔FR1能量值较术前下降(P0.05),与正常对照组差异无统计学意义(P0.05),术后喉腔FR1~FR4能量值与术前及对照组比较差异无统计学意(P0.05)。结论扁桃体肥大患者扁桃体切除术后口咽腔的体积扩大、气流通道增宽,改变了头腔、口腔的高频共振,且术后一个月左右均恢复至正常水平。
[Abstract]:Objective to investigate the characteristics of vocal resonance in patients with tonsillar hypertrophy before and after tonsillectomy. Methods 38 patients with tonsillar hypertrophy (tonsillar hypertrophy group, 25 patients with large degree II and 13 patients with high degree III) were measured by multi-channel speech analysis system. The characteristics of head cavity, oral cavity, larynx cavity and thoracic cavity resonance were counted before tonsillectomy, one month after tonsillectomy and 40 normal men (control group). 0~999Hz (FR1), 1000 鈮，
