Investigation on 122 patients of vertigo and dizziness hospitalized as emergency

Ⅰ．はじめに

　日常診療で，めまいを主訴とする症例を診察する機会は多い。その原因は多彩で，受診する科も耳鼻咽喉科，内科，脳神経外科，救急部とさまざまであり，病態の把握は困難である。時に生命に影響する重篤な中枢性疾患に遭遇することもある。今回，当院耳鼻咽喉科に緊急入院しためまい症例について検討したので報告する。

　We studied 122 emergency patients with acute vertigo who were admitted to National Hospital Organization Kumamoto Medical Center from april 2007 to June 2008. The most frequent disease was benign paroxysmal positional vertigo（13.9％）,followed by vertibular neuritis（13.1％）,inner ear disorder（13.1％）,Meniere's disease（11.5％）,central vertigo（5.7％）,and sudden deafness with vertigo（4.1％）.

　The patients with central vertigo were diagnosed using brain MRI. Brain MRI was considered to be a first-line clinical examination for patients with vertigo and dizziness hospitalized as emergency.
