Study Design:
Retrospective study.
Objective:
To evaluate patient demographics, surgical management, and complications of orbital and orbitozygomaticomaxillary complex (OZMC) fractures treated at a district hospital in Norway.
Methods:
The medical records of patients with orbital fractures treated at Aalesund hospital between January 2002 and July 2017 were reviewed. Data on demographics, signs and symptoms, cause of injury, fracture type, associated fractures, surgical management, and complications were collected.
Results:
A total of 36 patients were reviewed. Males predominated (1:4.1), and fractures occurred mostly in patients 40-59 years (mean 41.8 years). Interpersonal violence was the leading cause of injury, followed by falls. Alcohol was significantly associated with assault caused fractures (P = .001). Orbitozygomaticomaxillary fractures were the most frequent, followed by pure orbital fractures. Clinical findings included periorbital ecchymosis (72%), swelling (56%), sensory nerve dysfunction (53%), diplopia (22%), and restricted eye motility (22%). Commotio cerebri was observed in more than half of our sample and 47% had other facial bone fractures. Referral to tertiary hospitals was done in 19% of the cases. The main treatment done was open reduction and internal fixation (ORIF) (45%). Infection was diagnosed in 17% and managed with antibiotics.
Conclusions:
The incidence of orbital and OZMC fractures in Moere and Romsdal county in western Norway was low, occurring mainly in males over 40 years. The mechanism of injury was predominantly interpersonal violence and falls. A high proportion of the sample had minor traumatic brain injury (mTBI).
