Orbital fractures and concurrent ocular injury in a New Zealand tertiary centre

BackgroundOrbital fractures are a common presentation to acute care and carry an associated risk of ocular injury, however, previous research has not investigated injury rates by fracture category. These patients are frequently assessed by non-ophthalmic clinicians, however, limited data exists regarding referral patterns and how this impacts recorded injury rates (1–3).MethodsWe performed a retrospective review of all orbital fractures presenting to a tertiary hospital in Christchurch, New Zealand between March 2019 and March 2021. Data including mechanism of injury, fracture type, demographic characteristics, and associated ocular injury were recorded.Results284 patients with orbital fractures were identified. 41% of patients had isolated wall fractures, while 59% had complex orbitofacial fractures. Fractures were more common in males, and occurred more frequently in young individuals. The most common mechanism of injury was interpersonal violence (32%), followed by falls (23%). 41% of patients were reviewed by ophthalmology (n = 118). Of those, 33% had an associated ocular injury. Severe ocular injury (defined as vision threatening, requiring globe surgery or acute lateral canthotomy and cantholysis) occurred in 4.9% of those with formal ophthalmic review. 0.7% of patients required intraocular surgery or lateral canthotomy due to their orbital fracture.ConclusionOrbital fractures have a high rate of concurrent ocular injury in our study population, though rates of subsequent intraocular surgery are low. There was no significant difference in injury rates between isolated and complex fracture categories. Vision-threatening ocular injury occurred in 4.9% of fractures

Idiopathic myositis ossificans of the lateral pterygoid muscle in the paediatric patient: A case report

Myositis ossificans traumatica rarely affects the muscles of mastication. Since 1924, there has only been one case reported to affect the muscles of mastication in the paediatric population. The purpose of this paper is to present an 11-year-old girl with calcification of her right lateral pterygoid muscle with no evidence of previous trauma to the muscle. The clinical history and radiographic features resembled an extremely rare form of myositis ossificans also known as myositis ossificans idiopathica
