외안각절개에 의한 안와골절의 내시경 치료 = ENDOSCOPIC TREATMENT OF BLOWOUT FRACTURE BY LATERAL CANTHAL INCISION

다국어 초록 (Multilingual Abstract)

Blowout fracture is frequently encountered in facial bone trauma. It used to be reduced through, so called, subcilliary or transconjunctival incisions. Although these incisions facilitate to explore the bony orbital walls, they can induce some unwilling changes of soft tissues due to skin incision itself. The soft tissue of lower lid area may be more susceptible to trauma, even surgical than the lateral canthal area due to its fine structure.
Seven patients with blow out fractures were treated by endoscopic surgery through small incision of lageral canthal area. They have variable degree of orbital fat herniation, diplopia, and bony defect. Through small lateral canthal skin incision, endoscopy was easy to identify fracture site and made it possible to introduce the sealing material for bony defect.
This procedure left inconspicuous scar in the lateral canthal ares. Moreover, it seemed to be avoidable the possible hazardous external changes over the lower orbital area, and to be simultaneous successful treatment.
