title: Isolated orbital floor fractures in the paediatric patient: case series and review of management.
abstract: Orbital injuries warranting surgical intervention are infrequent in the paediatric population, but 'blowout, trap door' fractures are unique in children and may constitute a relative surgical emergency. A retrospective review of isolated orbital floor fractures at the Royal Children's Hospital of Melbourne over a 10-year period was undertaken to evaluate the outcome of those patients who required surgical exploration. Twenty-two patients with documented isolated orbital floor injuries were studied. Preoperative signs and symptoms including diplopia, ocular motility, paresthesia, enophthalmos, hypoglobus, and the presence of nausea and vomiting were recorded. Thirteen patients underwent non-surgical management and nine patients underwent surgical exploration of the orbital floor via a trans-subconjunctival approach to reduce any entrapped soft tissue. Postoperative follow-up of these patients varied between 1 month and 18 months and none had any visual disturbance or diplopia in central gaze; however, two patients experienced diplopia in upward gaze at follow-up, although this did not impair the quality of life. Due to the risk of permanent soft tissue damage from the entrapment of the periorbita with or without extraocular muscle tissue, it is recommended that exploration be undertaken as soon as possible to minimize the risk of persistent diplopia due to impaired ocular motility.
