手術により嚥下改善を認めたForestier病の1例

A case of improvement of dysphagia after surgical treatment for Forestier's disease

はじめに

　Forestier病（強直性脊椎骨増殖症）とは，1950年にForestierら^1）が報告したことでよく知られている疾患である。耳鼻咽喉科領域では頸椎前面の骨増殖による咽喉頭異常感，嚥下障害，嗄声や呼吸困難^2,3）などの原因となることが報告されている。今回われわれは，本疾患による長年の嚥下障害を主訴とした1例に対して外科的治療を行い，嚥下機能が著明に改善したので，手術の要点と若干の文献的考察を加えて報告する。

　We report a case of Forestier's disease with markedly improved dysphagia after surgical treatment. A 76-year-old male had been suffering from dysphagia for several years. Laryngeal endoscopy revealed a protrusion of the posterior pharyngeal wall. X-Ray and computed tomography showed an anterior protrusion especially at the vertebral body from the 3^rd to 4^th cervical vertebra. Surgery was performed to avoid damage to the superior laryngeal nerve. Additionally, it was considered that our treatment against dead space at the site of excision not only prevents postoperative hematoma and edema but also improves swallowing function in the early postoperative period.
