title: Subperiosteal orbital hematoma after balloon sinus dilation.
abstract: A retrospective case report of an orbital hematoma resulting from balloon sinus dilation during functional endoscopic sinus surgery is presented. The authors propose that this event may be because of shearing of venules that drain in the superior periorbital channels related to microfractures caused by the balloon dilation. To the authors' knowledge, this is the first report of orbital hematoma in the setting of balloon sinus dilation.
