Congenital clefts of the larynx are rare and usually found dorsally. An anterior or ventral cleft of the larynx is extremely rare. Only a few patients with this defect have been reported in the literature. The purpose of this paper is to present a patient having an anterior and posterior laryngeal cleft together. A 20-year-old man presented with a history of dysphonia since childhood. He did not report symptoms of swallowing or respiration, and had no history of neck trauma. Findings of videolaryngoscopy showed a grossly abnormal larynx. The anterior commissure was wider than normal, and the vocal folds did not show a fusion anteriorly. There was an interarytenoid cleft posteriorly. A neck CT with 3D reconstruction demonstrated a ventral cleft or nonfusion of the thyroid cartilage with a posterior cricoid cleft. Barium swallow study was in normal limits. Since the patient did not have any problem with swallowing or respiration, no surgical intervention was planned, and the patient was put on speech therapy, which revealed improvement in voice. To our knowledge, this is the first case of a combined laryngeal cleft. The diagnosis is established by the clinical symptoms, endoscopic evaluation, and radiographic examinations including 3D and barium studies.
先天性喉裂很少见，通常位于背部。喉的前或腹侧裂极为罕见。仅有少数患有这种缺陷的患者在文献中报道过。本文旨在介绍一位同时患有喉前裂和后裂的患者。一位 20 岁的男性，自童年起就有声音嘶哑病史。他没有吞咽或呼吸症状，也没有颈部外伤史。喉镜检查结果显示喉部严重畸形。前联合比正常宽，声带在前方没有融合。后联合处有声带间裂。颈部 CT 加 3D 重建显示甲状软骨腹侧裂或未融合，环状软骨后裂。钡餐检查正常。由于患者吞咽和呼吸均无问题，未计划进行手术干预，仅为患者制定了言语治疗计划，该计划显示出了声音的改善。据我们所知，这是首例同时患有喉裂的病例。通过临床症状、内镜评估以及包括 3D 和钡餐研究在内的影像学检查来确诊。
