목적 : 38세 남자 환자가 넘어지면서 발생한 안와골절 후 상악동으로의 안구 탈구 1예를 경험하여 이를 보고하고자 한다. 증례요약 : 38세 환자가 작업도중 넘어지면서 좌안 수상 후 좌안의 시력 상실 및 출혈을 주소로 본원 응급실에 내원하였다. 내원 당시 좌안 무광각 상태였으며 안구는 안와내에서 관찰되지 않았다. 안면골전산화단층촬영에서 상악동으로 안구가 탈구된 것이 관찰되었으며 안구의 파열소견은 보이지 않았고 시신경의 상태는 정확히 알 수 없었다. 수상 10시간 후 전신 마취하에 안구를 안와내로 복원시키고 장골이식편을 이용한 안와골절 정복술을 시행하였으며 파열된 외안근은 일차적으로 봉합하지 않았다. 4개월 뒤 좌안의 유리체 혼탁을 제거하기 위한 유리체 절제술을 시행하였다. 결론 : 복원된 안구에서 안구파열의 흔적은 관찰되지 않았으나 시력은 무광각상태였고 안구운동은 모든 방향에서 중등도의 장애를 보였다. 4개월 뒤 시행한 유리체 절제술 후에도 시력은 무광각상태로 시력회복은 얻지 못하였지만 내전, 상전 및 외전의 안 운동은 호전 소견을 보였다. 저자들은 국내에서 보고된 적이 없는 안와골절 후 발생한 상악동으로의 안구 탈구를 경험하였고 비록 시력은 회복되지 못하였으나 수술 후 미용적, 기능적으로 비교적 좋은 결과를 얻었기에 간단한 문헌고찰과 함께 보고하고자 하는 바이다.

Purpose: We report a case of a 38-year-old man who suffered a blowout fracture of the orbital wall with an intact eyeball entrapped within the maxillary sinus after trauma. Case summary: The 38-year-old man was admitted to the emergency room after sustaining a work-related trauma. His chief complaints were loss of vision and bleeding from the left periorbital area. He had no light perception and no eyeball was found in the orbit. Facial CT revealed that the intact eyeball was entrapped within the maxillary sinus. The condition of the optic nerve was difficult to ascertain. Ten hours after post-trauma, reduction surgery was done with a graft from the iliac bone. Ruptured extraocular muscles were not primarily sutured. After four months, vitrectomy was performed on the left eye. The eyeball was repositioned in its place. He had no light perception. Extraocular motility improved at the last follow-up examination. Conclusions: We report the dislocation of the eyeball globe into the maxillary sinus after a blowout fracture. Visual acuity showed no light perception as a result of central retinal artery occlusion and optic nerve injury. We were able to obtain a good aesthetic and functional result after the operation.
