title: Atypical traumatic subperiosteal orbital hematoma treated by surgical evacuation.
abstract: Subperiosteal orbital hematoma occurs rarely after blunt trauma. However, this is of importance, as this condition may cause ocular symptoms. The major characteristics of subperiosteal orbital hematomas are painful proptosis, downward displacement of the globe, absence of lid ecchymosis, chemosis without subconjunctival hemorrhage, and motility impairment. Visual impairment is known as a rarely presenting symptom. A 22-year-old male patient presented with right periorbital ecchymosis, swelling, and diplopia with upper lateral gaze limitation. Besides, the patient complained of lower visual field disturbance. Radiologic evaluation revealed traumatic subperiosteal orbital hematoma. The hematoma was evacuated through a lacerated wound on the right lateral eyebrow with additional incision. After the hematoma evacuation, the orbital symptoms are restored. Postoperative computed tomographic scans showed normally restored orbital space without any evidence of remnant hematoma or rebleeding. In case of subperiosteal hematoma, early detection and complete surgical evacuation is crucial for preventing possible complications and sequelae.
