CLINICAL ANALYSIS OF POSTOPERATIVE ENOPHTHALMOS IN CASES OF ORBITAL BLOW-OUT FRACTURE

Abstract

　Surgical repair for blow-out fractures aims to improve enophthalmos and eye movement.

　We examined the postoperative outcomes of 83 patients who had undergone surgery for blow-out fracture of the orbit at our department from April 2000 to April 2014. We examined the features of postoperative enophthalmos in the 47 cases for which both pre- and postoperative data were available. Except in cases with inferior-wall linear type fractures, we performed surgery using an endoscope to remove all the isolated splinters of bone. We used silicon plates and the balloon as needed.
　Among the cases of medial wall fracture in which surgery was performed, none of the patients felt their own enophthalmos. In cases of inferior-wall fractures, a correlation was observed between the fracture extent and the presence of postoperative enophthalmos. Among cases with both types of fracture, 25% felt their own enophthalmos, although no significant correlation was observed between the fracture area and the occurrence of postoperative enophthalmos.
