저자들은 영남대학교 영남의료원 치과로 교통 사고후 부정유합으로 인한 부정교합으로 저작 곤란을 호소하며 내원한 환자를 상악골 수평 및 후방 분절 골절단술을 시행해 다음과 같은 결과를 얻었다. 1. 교통 사고후 부정유합된 상악골을 수평 및 후방 분절 골절단술을 이용하여 전방 치열의 반대 교합과 구치부의 개교 및 scissor's bite를 해소했다. 2. 술후 감염등 특기할 만한 합병증은 발생하지 않았으며 술후의 종창은 48시간이 지나면서 서서히 감소했다. 3. 수술후 악간고정은 8주간 시행했으며 악간 고정 제거 1주후 정상적인 개구가 가능했다. 4. 절단된 상악골 고정시 확고한 고정과 회귀성향을 줄이기 위해 miniplates로 고정했다.

Background: Conventional correction of malunioned zygoma requires complete regional exposure through a bicoronal flap combined with a lower eyelid incision and an upper buccal sulcus incision. However, there are many potential complications following bicoronal incisions, such as infection, hematoma, alopecia, scarring and nerve injury. We have adopted a zygomaticofrontal suture osteotomy technique using transconjunctival incision with lateral paracanthal extension. We performed a retrospective review of clinical cases underwent correction of malunioned zygoma with the approach to evaluate outcomes following this method. Methods: Between June 2009 and September 2015, corrective osteotomies were performed in 14 patients with malunioned zygoma by a single surgeon. All 14 patients received both upper gingivobuccal and transconjunctival incisions with lateral paracanthal extension. The mean interval from injury to operation was 16 months (range, 12 months to 4 years), and the mean follow-up was 1 year (range, 4 months to 3 years). Results: Our surgical approach technique allowed excellent access to the infraorbital rim, orbital floor, zygomaticofrontal suture and anterior surface of the maxilla. Of the 14 patients, only 1 patient suffered a complication-oral wound dehiscence. Among the 6 patients who received infraorbital nerve decompression, numbness was gradually relieved in 4 patients. Two patients continued to experience persistent numbness. Conclusion: Transconjunctival incision with lateral paracanthal extension combined with upper gingivobuccal sulcus incision offers excellent exposure of the zygoma-orbit complex, and could be a valid alternative to the bicoronal approach for osteotomy of malunioned zygoma.
