Ⅰ　はじめに

　耳鼻咽喉科診療の日常診療において下咽頭，食道異物はしばしば遭遇する疾患であり，その大部分は魚骨であるといわれている^1）。魚骨異物は魚骨周囲の感染，膿瘍形成などの合併症をきたすことがあり^2），魚骨異物が疑われる場合には，異物の速やかな同定および摘出が重要である。今回われわれは頸部外切開による摘出術を要した下咽頭，食道魚骨異物の2例を経験したので報告する。

　We reported two cases of a foreign body in the hypopharynx and esophagus,removed by an external neck incision. The first case was a 50-year-old female who complained of a sore throat after eating a fish. CT scan revealed a fish bone in her hypopharynx.

　The foreign body was removed by lateral neck incision. The second case was a 70-year-old male, who presented with anterior neck swelling after swallowing of a fish.

　CT scan revealed a fish bone in his esophagus,and an abscess formation was detected. The foreign body was removed following transcervical drainage of the abscess.
