오래된 안와 내벽 골절이 동반된 만성 부비염에서 동시에 시행한 안와 내벽 골절 정복술 및 내시경 수술 1예

Minor and major complications can occur during endoscopic sinus surgery. Damage to an anatomic structure adjacent to a sinus is always a possibility during ESS. The lamina papyracea is very thin and may be fractured with relatively minor truma. The presence of orbital fat, as well as the distorted anatomy at the fracture site, may make endoscopy sinus surgey difficult or impossible because orbital fat is a landmark that surgeons should not cross for fear of injury to orbital content, such as extraocular muscles, vasculature, and neural structures. If there may be combined disruption of the medial orbital wall with orbital blowout fracture, orbital complication after ESS may be very high. We report a case of endoscopic sinus surgery of chronic sinusitis and nasal polyps associated old medial blowout fracture with a review of literature. (J Clinical Otolaryngol 2014;25:199-203)
