視力，視野障害をきたした蝶形骨洞粘液嚢胞の一例

A CASE OF SPHENOID SINUS MUCOCELE CAUSING DISTURBANCES OF VISUAL ACUITY FIELD

緒言

　副鼻腔Mucoceleの発生は諸家の報告によれば前頭洞，篩骨洞に多く，蝶形骨洞，上顎洞については甚だ稀有とされる．しかし後者について1960年以後はMcHenry^11）（1960），Lundgren^9）（1961），Norman1^14）（1964），Pincus^18）（1964），Nevins^13）（1967），Waldman^22）（1967），Nugent^15）（1970）等の報告を見るが現在まで総合的に80数例にすぎないといわれる。最近我々は視力，視野障害を主訴とした蝶形骨洞粘液嚢胞（Sphenoid Sinus Mucocele）の症例を経験したので文献的考察と合わせて報告する。

A case of sphenoid sinus mucocele was reported with review of references. Patient was 59 years old male and complained of disturbances of the visual acuity and field.

The roentogenogram showed the erosion of base of sella turcica and destructive dilatation of sphe-noidal sinus.

This mucocele occupying sphenoid sinus was extirpated transnasaly. Above visual disturbances, however, did not recover satisfactorily.

After about one month, we performed craniotomy, found localized bulge through left parasellar, dura and arachinoidal adhesions around the optic nerves and chiasm. When the latter was detouched. visual disturbances were markedly improved in right visual acuity and field.

We consider this procedure should be tried se-condarily, if the visual disturbances do not recover after transnasal operation.
