Case Report
Trauma-induced orbital blowout fracture (OBF) with eyeball displacement into the maxillary sinus is rare./r/nWe present the case of a 14-year-old with a closed head injury, OBF, and displacement of the eyeball into the maxillary sinus following a car accident. A prompt transconjunctival access surgery was performed for eyeball repositioning and orbital reconstruction in a single session, mitigating anaesthesia-related risks associated with multiple surgeries. At the 12-month follow-up, his visual acuity was 20/200. Despite limited eye movement and optic nerve atrophy, overall satisfaction with the ocular appearance was achieved./r/nThis report offers novel insights into the mechanisms of OBF occurrence and the development of postoperative complications.
