To report on the results of using a lateral thyrotomy approach on the paraglottic space to gain greater access for laryngocele resection under direct vision.
A 26-year prospective and retrospective study. The study was conducted on 10 adult patients (5 men and 5 women) who had laryngocele of varying size on the paraglottic space. Six of the patients had internal laryngocele and four had exteriorized laryngocele. Five laryngoceles were left-sided, three were right-sided, and two were bilateral.
A V-shaped, full-thickness thyroid lamina resection with the triangle base at the superior border and the apex at a point midway of the thyroid lamina vertical extent was performed.
A V-shaped lateral thyrotomy made exposure to the paraglottic space possible for direct submucosal laryngocele dissection. This approach has presented no complications to date. Postoperative minor edema or hematoma was found in the aryepiglottic and ventricular folds, but this disappeared within a few days. There was no recurrence; the minimum follow-up was 1 year.
The triangular lateral thyrotomy approach provided access to the paraglottic space and superb visibility for resection of laryngocele of any size under direct vision, thus avoiding recurrence, morbidity, and complications.
报告采用甲状软骨外侧切开入路处理声门旁间隙，以便在直视下更充分地进行喉膨出切除术的结果。
一项为期26年的前瞻性和回顾性研究。该研究针对10例成年患者（5例男性和5例女性）开展，这些患者的声门旁间隙存在不同大小的喉膨出。其中6例患者为内喉膨出，4例为外突性喉膨出。5例喉膨出位于左侧，3例位于右侧，2例为双侧。
进行V形全层甲状软骨板切除术，三角形底边位于甲状软骨上缘，顶点位于甲状软骨板垂直范围中点处。
V形甲状软骨外侧切开术使暴露声门旁间隙以进行直接黏膜下喉膨出剥离成为可能。该方法迄今为止未出现并发症。术后在杓会厌襞和室襞发现轻微水肿或血肿，但数天内即消失。无复发情况；最短随访时间为1年。
三角形甲状软骨外侧切开入路可进入声门旁间隙，并在直视下为切除任何大小的喉膨出提供极佳视野，从而避免复发、发病及并发症。
