興味ある経過をとった視神経管損傷例

抄録

Among the complications resulting from side injuries during operations for chronicsinusitis, visual impairment is considered not only a medical but also a serious social problem. we have recently experienced a case referred to us for treatment of visual impairment following an operation for sinusitis.
This patient, a 51-year-old man, first had a tooth extracted because of swelling of the buccal region and nasal discharge, but the symptoms persisted and he then visited the ENTdepartment of a hospital where the presence of a tumor was suspected on x-ray examination. Anoperation was performed but on the 3rd postoperative day he suddenly complained of visual impairment (blindness). Various treatments were tried without improvement and he was then referred to our hospital for further treatment.
Reoperation at our hospital has resulted in some return of his light sense as he can now perceive faintly the light from a window, but no further improvement of vision hasbeen observed. This patient is still under observation.
