    Abstract:
    PURPOSE: Paediatric orbital fractures are rare. Existing literature demonstrates wide variation in estimates of incidence, aetiology, management protocols and outcomes. Despite this, it is generally acknowledged that orbital fractures with entrapment of the extraocular muscles constitute a surgical emergency due to the potential for persistent diplopia secondary to muscle ischaemia and necrosis. METHODS: This retrospective study was conducted to determine the characteristics and outcomes of management of orbital fractures amongst the paediatric population. It involved patients presenting to a major trauma unit in London between 2010 and 2020. RESULTS: Thirteen patients with isolated orbital fractures presented to our unit in this period. The average age was 13 years. Surprisingly the predominant aetiology was interpersonal violence. The most common fracture pattern involved the orbital floor and medial wall. One medial wall fracture case was missed in the emergency department. Eight patients required surgical intervention due to diplopia caused by muscular entrapment of extraocular muscles; the final patient had a large defect resulting in enophthalmos requiring a large titanium plate. A transconjuctival approach was preferred for surgical access and resorbable sheet was used in the remaining cases. Five patients had nausea, vomiting or bradycardia associated with the oculocardiac reflex. Surgical intervention occurred within 24-48 h of injury in 6 cases. Resolution of diplopia occurred in 7 patients within 6 months. CONCLUSION: Paediatric patients with orbital fractures should be assessed on the day of injury by a maxillofacial surgeon. Due to the risk of persistent diplopia, urgent surgical intervention in patients with entrapment of extraocular muscles should occur as soon as possible.
