目的探讨声带息肉术后发声功能恢复的时间及规律。方法对51例声带息肉患者(患者组)分别于支撑喉镜术后1、2周及1、3、6个月进行嗓音声学指标基频(fundamental frequecy,F0)、基频微扰(jitter)、振幅微扰(shimmer)、噪/谐比(noise to har...目的探讨声带息肉术后发声功能恢复的时间及规律。方法对51例声带息肉患者(患者组)分别于支撑喉镜术后1、2周及1、3、6个月进行嗓音声学指标基频(fundamental frequecy,F0)、基频微扰(jitter)、振幅微扰(shimmer)、噪/谐比(noise to harmonic ratio,NHR)及嗓音障碍指数(voice handicap index,VHI)调查,对51例嗓音正常人(正常对照组)进行嗓音学分析及VHI调查,对比分析术后嗓音恢复情况。结果患者组F0较正常对照组降低,jitter、shimmer、NHR较正常对照组升高,差异有统计学意义(P<0.05);随着时间的推移,患者组F0逐渐升高,其余4个指标均有一定程度的降低,其中F0、jitter、shimmer、NHR在第1个月接近正常对照组,且与3、6个月时差异无统计学意义(P>0.05),VHI评分在3、6个月时与正常对照组相近,且差异无统计学意义(P>0.05)。结论声带息肉患者支撑喉镜术后嗓音质量逐渐恢复,术后1周内禁声休息,1个月内休声,1个月以后可正常、正确用嗓。展开更多
目的:评价早期喉癌激光术后对声带不同功能特征的影响。方法:通过计算机网页检索医学相关的主要数据库:PubMed、Web of Science和Embase数据库,由2位工作人员同时对搜索的相文献进行阅读和筛选,从筛选的文献中提取与研究目的相关的数据...目的:评价早期喉癌激光术后对声带不同功能特征的影响。方法:通过计算机网页检索医学相关的主要数据库:PubMed、Web of Science和Embase数据库,由2位工作人员同时对搜索的相文献进行阅读和筛选,从筛选的文献中提取与研究目的相关的数据。对提取的数据用Stata 14.0软件进行网状Meta分析,获取早期喉癌激光术后对声带不同声音特性的影响。结果:通过文献检索和筛选结果共纳入符合要求的文献9篇,统计学分析结果表明,激光手术治疗早期喉癌能够显著降低声嘶评估量表和嗓音障碍指数评估总分。结论:激光治疗早期喉癌术后,可以降低声嘶评估量表和嗓音障碍指数评估总分,提高术后声带总体功能,改善患者术后的生活质量,但喉癌术后早期声带在功能和生理方面没有明显的改善。展开更多
