先天性頸嚢胞41症例の臨床的検討

Clinical Studies on 41 Cases of Congenital Cervical Cysts

　はじめに

　頸部の先天性嚢胞のうち，甲状舌管嚢胞は最も高頻度にみられる疾患である。また，側頸部の鰓嚢胞は悪性腫瘍との鑑別が臨床的に重要である。

　本稿では，先天性頸部嚢胞症例の臨床症状，検査所見および手術所見を文献的考察を加えて検討を行ったので報告する。

Forty-one cases of congenital cervical cysts were reported.

1. Thyroglossal cyst (24 cases) : The ages ran-ged from 4 to 72 years. 90% of cystslocated between the hyoid bone and the thyroid cartilage.

2. Branchial cleft cyst (17 cases) : One lateral cervical cyst was type I , 11 were type II, and 2 were type III according to classification of Bailey.

3. Thyroglossal carcinoma showed almost simi-lar clinical features to those of benign cysts. But preoperative ultrasonography showed calcification or a solid mass in the cyst suggesting of malignant tumor.
