Clinical Study of Blowout Fractures

Abstract

We studied 86 cases of orbital blowout fracture treated in our in-patient department between October 1981 and June 1999. Orbital floor fractures occurred in 51 cases , medial orbital wall fractures occurred in 12 cases, and both types occurred in 23 cases . Surgery was performed in 79 of these cases under general anesthesia.

Association between preoperative inferior rectus muscle swelling and outcomes in orbital blowout fracture

“…The reported factors associated with a poor prognosis in surgically treated patients with orbital fracture include: (1) extraocular muscle injury (Smith et al, 1984;Gilbard et al, 1985;Lisman et al, 1987;Watanabe et al, 2000;Oba et al, 2001;Kase, 2007), (2) preoperative severe double vision (Kase, 2000;Watanabe et al, 2000;Lee et al, 2005), and (3) young patients (de Man et al, 1991;Watanabe et al, 2000;Burnstine, 2002;Kamijo et al, 2005;Kwon et al, 2005). Concerning extraocular muscle injury, Kase (2000) reported that extraocular muscle swelling and deviation are factors associated with a poor prognosis.…”

“…One of the possible causes may be extraocular muscle injury (Smith et al, 1984;Gilbard et al, 1985;Lisman et al, 1987;Watanabe et al, 2000;Oba et al, 2001;Kase, 2007). We (Matsunaga et al, 2009) previously evaluated outcomes 1 year after the surgery in patients with orbital blowout fracture who underwent reconstruction using a bone autograft, and reported marked swelling of the extraocular muscle close to the fracture site on preoperative CT images as a finding common to patients in whom impaired eye movements remained.…”
