顔面外傷時の眼筋麻痺による複視と鼻科的手術の必要性

THE NEED OF OPERATIVE CORRECTION IN CASES OF DIPLOPIA DUE TO EXTERNAL TRAUMA OF THE FACE

　Ⅰ．緒言

　顔面外傷によりしばしば複視が起こる。その原因には眼窩壁骨折による物理的な眼球の転位および眼筋の運動障害，眼筋への支配神経の障害による眼筋麻痺などが考えられる。さらに視力障害，調節障害なども複視として訴えられることがある。われわれは最近経験した症例より眼球運動障害による複視の原因を考察したので報告する。

Five cases of diplopia due to traumatic origin are reported.

Case Ⅰ. Diplopia resulted from a brow out fracture on the eye. A complete recovery was seen after a surgical treatment.

Case Ⅱ. Diplopia resulted from a traumatic fracture of the orbital rim. An operative correction was attempted but a complete recovery was not seen.

Case Ⅲ. Diplopia resulted from a brow out fracture on the eye but a spontaneous recovery occurred after one week of observation.

Case Ⅳ. Diplopia resulted from a combined traumatic fracture of the parietal and mandibular bones as well as the bones forming the orbital rim. No improvement of the affection was seen after surgical attempt at correction.

Case Ⅴ. Diplopia resulted as an aftermath of a radical sinus operation that covered the maxillary and ethmoidal sinuses. An attempt was made for a surgical correction but a complete recovery was not seen.
