OBJECTIVE/HYPOTHESIS: To determine whether injection laryngoplasty or medialization laryngoplasty is more effective in the treatment of unilateral vocal fold paralysis.
A retrospective study of patients with unilateral vocal fold paralysis who underwent either injection or medialization laryngoplasty at the University of Arkansas for Medical Sciences between July 29, 2003 and March 8, 2005.
The data analyzed included patient characteristics and type of intervention, along with the pretreatment and posttreatment voice parameters of videostrobolaryngoscopy, perceptual analysis, and patients' subjective voice assessment.
Nineteen patients were evaluated. The average time from intervention to posttreatment evaluation was 3 (range, 1-9) months. Improvements were demonstrated in all three voice parameters in both the injection and the medialization groups. No significant differences were found in the degree of improvement between the two groups. Videostrobolaryngoscopy and the perceptual analysis, both rated by the authors, correlated well with each other, but they both correlated poorly with the patients' subjective voice analysis.
Injection and medialization laryngoplasty were comparable in their improvement of subjective and objective voice outcomes. Both treatment modalities should be included in the otolaryngologist's armamentarium for managing unilateral vocal fold paralysis.
目的/假设：确定注射喉成形术或喉内移术在治疗单侧声带麻痹方面哪种更有效。
对2003年7月29日至2005年3月8日在阿肯色大学医学科学分校接受注射或喉内移术的单侧声带麻痹患者进行回顾性研究。
分析的数据包括患者特征和干预类型，以及电视频闪喉镜检查、感知分析和患者主观嗓音评估的治疗前和治疗后嗓音参数。
对19名患者进行了评估。从干预到治疗后评估的平均时间为3（范围1 - 9）个月。注射组和喉内移术组的所有三项嗓音参数均有改善。两组之间的改善程度无显著差异。作者进行的电视频闪喉镜检查和感知分析彼此相关性良好，但与患者的主观嗓音分析相关性均较差。
注射喉成形术和喉内移术在改善主观和客观嗓音结果方面具有可比性。两种治疗方式都应纳入耳鼻喉科医生治疗单侧声带麻痹的方法中。
