当科における一側性眼球突出の臨床的観察

CLINICAL OBSERVATIONS ON EXOPTHALMOS

　I．はじめに

　眼球突出は種々なる原因によつて引き起こされるが，鼻副鼻腔疾患が眼球突出の原因となることが少なくない。しかしそのような場合にも鼻症状を欠くために，患者は無用な検査を強いられたり，視機能へ影響を及ぼした時点で，はじめて耳鼻科へ紹介されることがある。

　そこで今回われわれは昭和40年より昭和51年までの12年間に，一側性眼球突出を訴えて受診した患者が，耳鼻科領域のいかなる疾患において見られたかを統計的に調査するとともに，興味ある症例を加えてここに報告し，若干の検討を加えた。

　One hundred sixty two cases of unilateral exophthalmos who visited our clinic at the Hiroshima University Medical School from 1965 to 1976 were investigated statistically. Out of these numbers 103 cases 63. 5% were referred to us by other practicing ophthalmologists. One hundredcases or approximately 60% who suffered unilateral exophthalmos were due to lesions of the nose, paranasal sinuses and epipharynx. With the involvement of the paranasal sinus 54 cases were found suffering from cysts ; the frontal sinus appeared to be the most frequent followed by maxillary and ethmoidal sinuses in their turn. Malignant tumors were relatively frequently foundin those over 40 years old. Patients suffering paranasal sinusitis were mostly under 20 years old.

　Postoperative recurrence of the cyst which produced exophthalmos was found to be in six or ten years for frontal sinus involvement ; ten years in cases with ethmoidal sinus and about fifteen years in maxillary sinus.
