Analysis of symptoms according to areas of orbital floor in orbital inferior wall fractures.

Abstract

A considerable number of patients experiencing facial trauma are diagnosed with blowout fracture. Preoperative computed tomographic scan is often different from the actual surgical area. This study is restricted to orbital floor fracture. This study is expected to help speculating fracture site and making surgical plans according to symptoms of periorbital trauma. From March 2005 to September 2013, a total of 150 cases of orbital floor fracture surgeries have been analyzed. This study analyzed the preoperative symptoms at the certain fractured area of orbital floor, at the aspects of sagittal view of computed tomography, which is sectioned into anterior one-third, middle one-third, posterior one-third, and mixed types. Symptoms for analysis are diplopia, extraocular movement limitation, enophthalmos and other combined facial bone fractures, and the like. Fracture areas of orbital floor are 21 cases (14%) of anterior one-third, 47 cases (31%) of middle one-third, 7 cases (5%) of posterior one-third, and 75 cases (50%) of the mixed. Frequency of diplopia was 0 case, 24 cases (42.1%), 4 cases (7.0%), and 29 cases (50.9%), respectively. In the case of extraocular movement limitation, 0 case, 15 cases (39.5%), 2 cases (5.3%), and 21 cases (55.2%) were found, respectively. In the case of enophthalmos, 0 case, 5 cases (16.7%), 7 cases (23.3%), and 18 cases (60.0%) were found, respectively. The most commonly associated other facial bone fractures were nasal bone fractures. In the case of blowout fracture, diplopia, extraocular movement limitation, enophthalmos, and other symptoms are checked through physical examination. This study would help speculating fracture site and making surgical plans according to symptoms of periorbital trauma.
