後部副鼻腔嚢腫

抄録

Cysts developing in the posterior paranasal sinuses viz. the posterior ethmoidal sinus or sphenoid sinus manifest more often symptoms relevant to the eye or the brain than the ones to the paranasal sinuses.
The authors report 3 such cases and reviewed 90 other cases so far reported in the literature as to the incidence, age and sex distribution, specialities to which the patient sought medical aid first, duration of the disease, roentgenologic findings, treatments, pathology and bacteriology.
It was found that the prognosis of the visual disturbance depended mainly on the time lapse between the onset of symptoms and operation.
It seems important to perform an operation within two weeks of the appearance of the visual disturbance or one month at the latest.
The importance of the use of fiberoptic telescope in operations for a detailed observation of Incal natholoav and meticulous surgery at the critical region is stressed.
