ABSTRACT
PURPOSE: The purpose of this study was to identify the therapeutic effect of orbital reconstruction by transcaruncular approach on old medial orbital wall fracture. METHODS: We performed retrospective study on 23 eyes of 23 patients, who underwent orbital reconstruction with transcaruncular approach over six weeks after injury from July 1999 to August 2001. RESULTS: Nineteen cases had enophthalmos, preoperatively; five cases; 2 mm, seven cases; 3 mm, six cases; 4 mm, and one case; 5 mm, respectively. Postoperatively, we obtained enophthalmos less than 1 mm in 17 cases(89%). The exophthalmometry revealed that enophthalmos improved from 3.2+/-0.9 mm, preoperatively to 0.9+/-0.7 mm, postoperatively. Twelve cases had diplopia on the primary and downgaze, preoperatively. However, ten cases of them(83%) disappeared diplopia, postoperatively. Of the remaining two cases, one had persistent diplopia on the downgaze and the other had paralytic strabismus. CONCLUSIONS: We believe that the medial orbital wall repair through transcaruncular approach was a good way to correct enophthalmos and diplopia on old medial orbital wall fracture.
