妊娠中の5ヵ月間に急速に高度難聴に進行した1例

Abrupt Progressive Hearing Impairment in Pregnant Patient

I．はじめに

　妊娠，産褥にひきついで，耳鳴，難聴が発現することは，1885年Beane^1）以来多くの報告がある。しかし実際に文献を調べると，外国では，妊娠により耳硬化症の悪化する伝音難聴の進行が多い。感音難聴については，我が国では，1932年倉田^2）が初めて報告して以来，佐藤^3），立木^4），平島^5），鳥山^6）らの報告がある。しかし実際に難聴者を扱っていても，妊娠，産褥による難聴者は数少なく，筆者ら^7）の川崎市の身体障害者の集計でも183名の高度難聴者の中の2名にすぎなかった。

　今回妊娠初期のつわり症状様の，嘔気，嘔吐を初発症状として，耳鳴が発生してより5ヵ月の間に完全に両側高度難聴となった症例を経験したので，これを報告した。とくに分娩時には両側高度難聴となった患者の精神的な不安定さと，リハビリテーションに大きな問題があった。

　Abrupt and progressive hearing impairment in both ears in a 25-year-old pregnant female, was reported.

　The patient had been suffered from visual disturbances caused by cataracta, weakness of sight and congenital nystagmus. She had been operated on her cataracta for visual weakness at the age of 13.

　At four months pregnancy, the patient had been suffered from nausea, vomitting and gait disturbance caused by emesis or vestibular disturbance, and she had been treated by a gynecologist. One month later she had suffered from tinnitus and hearing impairment in both ears, and her audiogram showed 20-50 dB in the left, and 35-75 dB in the right ear. She had lost her hearing acuity completely before delivary.

　It was a sever problem that she was suffered from visual and hearing disturbance after delivary to have good communication with doctors, nurses, and her family to take advice for new born baby care.
