Abstract

Purpose

To characterize the location of orbital blowout fractures in Asian individuals.

Methods

This was a retrospective review of 470 consecutive Asian patients with orbital blowout fractures who presented to four tertiary care hospitals in Japan and China. Computed tomography (CT) characterized the location and severity of fractures involving the medial wall, the orbital floor, and/or the maxilloethmoidal strut.

Results

A total of 475 orbital blowout fractures were identified. More than one fracture location was involved in 19 % of all cases. The medial orbital wall was the most commonly involved location, presenting in 29 cases (61 %), of which 204 (43 %) were isolated medial blowout fractures. The orbital floor was the second most common location involved, present in 226 cases (48 %) with 150 isolated orbital floor fractures (32 %), while the maxilloethmoidal strut was involved in 45 cases (9 %) with 30 of those being isolated strut fractures (6 %). The majority of fractures (62 %) were classified as moderately severe, whilst 14 % were mild, and 24 % were severe. Associated nasal fractures were present in 16 % of the cases.

Conclusions

Orbital blowout fractures in Japanese and Chinese individuals occur most commonly in the medial wall. This is in contrast to previous reports on white individuals, who tend to sustain fractures involving the orbital floor rather than the medial wall.
