Congenital clefts of the larynx are rare and usually found dorsally. This case report describes a patient with a partial anterior nonfunsion, or ventral cleft, of the thyroid cartilage. This was first noted on computed tomography of the larynx used for delineation of carcinoma and was confirmed by horizontal whole mount histologic sections of the resected larynx. The thyroid cartilage suggested arrested fusion of the laminae in the middle to late embryonic period. This patient had an adult form of this rarely reported anomaly and the first, to our knowledge, detected with CT scan.
先天性喉裂罕见，通常位于背侧。本病例报告描述了一名患有甲状软骨部分前侧未融合或腹侧裂的患者。这一情况最初在用于诊断喉癌的喉部计算机断层扫描中被发现，并通过切除喉部的水平整体组织学切片得到证实。甲状软骨提示在胚胎中晚期板层融合停止。该患者患有这种罕见报道的异常的成人形式，据我们所知，这是首例通过CT扫描检测到的病例。
