True vocal cord failure (glottis) refers to the inability or failure of the larynx structure and vocal cords to produce sound. One of the optimal techniques for repairing this lesion is medialization laryngoplasty, which restores sound strength, continuity, and quality. Another technique is to create a Mini window in the periphery of false vocal cords. This study compared the effectiveness of medialization laryngoplasty with Gore-tex in two classic medialization laryngoplasty techniques and the Mini window method in the periphery of false vocal cords.
A total of 30 participants who had unilateral vocal cord paralysis due to various causes, such as surgery, metastasis, and intubation, were studied. After obtaining informed consent from patients, 15 participants were assigned to each group (classic or mini-window medialization laryngoplasty). Voice parameters, such as pitch, jitter, shimmer, and hoarseness, were evaluated before and after surgery. The duration of the surgery was also compared.
The Mini-Window method significantly improved sound quality, resulting in lower voice shimmer and shorter surgery duration.
While both methods are effective, the Mini-Window technique offers a more efficient surgery with reduced voice shimmer.
真性声带麻痹（声门）是指喉部结构和声带无法发出声音或发声失败。修复这种病变的最佳技术之一是喉内移术，它能恢复声音强度、连续性和质量。另一种技术是在假声带周边制造一个微型窗口。本研究比较了在两种经典喉内移术技术中使用戈尔泰克斯材料进行喉内移术与在假声带周边采用微型窗口方法的有效性。
共研究了30名因手术、转移和插管等各种原因导致单侧声带麻痹的参与者。在获得患者知情同意后，将15名参与者分配到每组（经典或微型窗口喉内移术）。在手术前后评估音高、抖动、闪烁和嘶哑等嗓音参数。还比较了手术时长。
微型窗口方法显著改善了音质，使声音闪烁降低，手术时长缩短。
虽然两种方法都有效，但微型窗口技术提供了一种更高效的手术，且声音闪烁减少。
