To study changes in Pediatric Voice Handicap Index (PVHI) and Pediatric Voice Related Quality of Life (PVRQOL) before and after adenotonsillectomy in short term follow up.
Quasi-experimental (before and after study). Eighty-six children aged 3-13 years (58 boys, 28 girls) with adenotonsillar problems (whether with obstructive or infectious surgical indications) who were admitted for adenotonsillectomy procedure. Parents of children were asked to complete PVHI and PVRQOL questionnaires prior to surgery and 1 month after it.
Reliability of the PVRQOL and PVHI was established by evaluation of Cronbach α value. Cronbach α for PVHI was 0.92 and for PVRQOL it was 0.83. Preoperative values for the PVHI were: mean±SD; 14.39±14.65. Preoperative values for the PVRQOL were: mean±SD; 92.60±10.82. PVHI showed significant improvement after surgery: mean±SD; 2.93±6.98 (P<0.001). Postoperative PVRQOL had a significant improvement: mean±SD; 98.11±5.82 (P<0.001).
Adenotonsillectomy improved PVHI and PVRQOL scores in children with adenotonsillar problems, regardless of obstructive or infectious surgical indications.
研究小儿扁桃体腺样体切除术短期随访前后小儿嗓音障碍指数（PVHI）和小儿嗓音相关生活质量（PVRQOL）的变化。
采用准实验性研究（前后对照研究）。86例年龄在3至13岁的儿童（58名男孩，28名女孩）因扁桃体腺样体问题（无论有无阻塞性或感染性手术指征）入院接受扁桃体腺样体切除术。要求患儿家长在手术前及术后1个月完成PVHI和PVRQOL问卷。
通过评估Cronbach α值确定PVRQOL和PVHI的可靠性。PVHI的Cronbach α值为0.92，PVRQOL的Cronbach α值为0.83。PVHI术前值为：均值±标准差；14.39±14.65。PVRQOL术前值为：均值±标准差；92.60±10.82。术后PVHI有显著改善：均值±标准差；2.93±6.98（P<0.001）。术后PVRQOL有显著改善：均值±标准差；98.11±5.82（P<0.001）。
扁桃体腺样体切除术可改善患有扁桃体腺样体问题儿童的PVHI和PVRQOL评分，无论有无阻塞性或感染性手术指征。
