A mucosal bridge of the true vocal fold is a rare, benign anatomical finding that can cause dysphonia. It has been described by some in the literature as "occult" as it is often not visibly evident on flexible nasopharyngolaryngoscopy or strobovideolaryngoscopy, but mistakenly diagnosed as a sulcus vocalis (Sataloff RT, Rosen C, Hawkshaw M. Occult mucosal bridge of the vocal fold. Ear Nose Throat J. 1997; 76(12):850).(2) Final diagnosis is usually not made until microscopic direct laryngoscopy is performed and palpation of the true vocal fold reveals the mucosal bridge (Tanaka S, Hirano M, Umeno H, Tanaka Y. Mucosal bridge of the vocal fold [Japanese].(4)Nippon Jibiinkoka Gakkai Kaiho. 1991; 94(12):1853-1856). We describe a case of a 15-year-old boy complaining of long-standing hoarseness and found to have bilateral mucosal bridges of the true vocal folds. Previous reports cite cases of a unilateral mucosal bridge. We believe this is the first reported case of bilateral mucosal bridges.
真声带的黏膜桥是一种罕见的良性解剖学发现,可导致声音嘶哑。一些文献将其描述为“隐匿性”,因为它在软性鼻咽喉镜或频闪喉镜下通常不易察觉,但被误诊为声带沟(Sataloff RT、Rosen C、Hawkshaw M. 隐匿性声带黏膜桥。耳鼻喉科杂志。1997;76(12):850)。(2) 直到进行显微镜直接喉镜检查并触诊真声带时,通常才做出最终诊断,发现黏膜桥(Tanaka S、Hirano M、Umeno H、Tanaka Y. 声带黏膜桥[日语]。(4)日本耳鼻喉科学会杂志。1991;94(12):1853-1856)。我们描述了一个 15 岁男孩长期声音嘶哑的病例,发现他有双侧真声带黏膜桥。先前的报告引用了单侧黏膜桥的病例。我们相信这是首例双侧黏膜桥的报道。
