Mucosal bridges are rare laryngeal lesions probably of genetic origin. They may cause dysphonia of varying degrees, especially when associated with other laryngeal lesions such as vocal sulci and cysts. Reports on mucosal bridges are rare, and the better treatment is inconclusive.
To report the authors' experience in 14 cases of mucosal bridge showing details on endoscopic examinations and treatment.
Retrospective study.
We reviewed the medical records of 14 patients with a diagnosis of mucosal bridge confirmed by videolaryngostroboscopy and direct laryngoscopy who attended the Outpatient Clinic of Voice Disorders of the Discipline of Otorhinolaryngology, Botucatu Medical School, São Paulo State University, São Paulo. Data collected included information on gender, age, symptoms, time of onset, history of intubation, smoking status, alcohol intake, associated laryngeal lesions, treatment, and GRBAS (grade of hoarseness, roughness, breathiness, asthenia, and stress) scale ratings.
Of 14 patients, 10 were females and four were males. There was a prevalence of adults (n=12), with only two of the patients being younger than 13 years (10 and 13 years). Mucosal bridges showed no correlations with smoking, alcohol intake, or gastroesophageal and sinonasal symptoms. Voice abuse was reported in 50% of the cases that consisted of patients who had high-voice demand occupations. In seven cases, mucosal bridges were associated with other laryngeal lesions, particularly vocal cysts and sulci. All patients who underwent surgery and phonotherapy showed improved vocal quality.
We documented 14 patients with dysphonia caused by mucosal bridge. Promising results were obtained with surgery.
黏膜桥是一种罕见的喉部病变，可能具有遗传起源。它们可能导致不同程度的声音嘶哑，特别是当与其他喉部病变如声沟和囊肿相关时。黏膜桥的报道很少，且更好的治疗方法尚无定论。
报告作者在 14 例黏膜桥患者中的经验，详细介绍内镜检查和治疗情况。
回顾性研究。
我们回顾了 14 例经视频喉镜和直接喉镜诊断为黏膜桥的患者的病历，这些患者均在圣保罗州立大学博图卡图医学院耳鼻喉科嗓音障碍门诊就诊。收集的数据包括性别、年龄、症状、发病时间、插管史、吸烟状况、饮酒情况、相关喉部病变、治疗方法以及 GRBAS（嘶哑、粗糙、气息、乏力和紧张度）量表评分。
14 例患者中，女性 10 例，男性 4 例。成人（n=12）居多，只有 2 例患者年龄小于 13 岁（10 岁和 13 岁）。黏膜桥与吸烟、饮酒、胃食管和鼻-鼻窦症状无关。50%的患者存在嗓音滥用，这些患者从事需要高声的职业。7 例患者的黏膜桥与其他喉部病变，特别是声带囊肿和沟相关。所有接受手术和语音治疗的患者的嗓音质量均得到改善。
我们记录了 14 例因黏膜桥导致声音嘶哑的患者。手术治疗效果良好。
