Results of Reconstruction of Orbital Wall Fracture With Bioresorbable Plate

Abstract

목적: 흡수성 삽입물인 MacroPoreⓡ orbital floor liner를 이용한 안와골절 정복술 시행 후 장기 재건 효과 및 합병증 여부를 알아보고자 하였다.

대상과 방법: Macroporeⓡ orbital floor liner를 이용한 안와골절 정복술을 시행 받고 6개월 이상 경과관찰된 환자를 대상으로 의무기록 검토를 통하여 안구함몰, 안구운동장애 및 복시의 결과를 분석하였다.

결과: 총 35명의 대상환자에 대하여 평균 14.0개월의 추적관찰이 이루어졌으며, 안구함몰이 일차 수술 적응증이 되었던 29명의 최종 경과 관찰 시의 평균 안구함몰은 0.90 mm이었고, 술 후 6개월에 비해 술 후 12, 18, 24개월째 모두 유의한 안구함몰의 진행 소견은 관찰되지 않았다. 술 전 안구운동장애 또는 복시 소견을 보였던 15명은 모든 예에서 증상이 소실 혹은 호전되었으며, 삽입물의 탈출, 감염, 안구운동 장애 악화 등의 합병증은 관찰되지 않았다.

결론: Macroporeⓡ orbital floor liner는 흡수에 따른 합병증 없이 안와골절 정복술의 삽입물로 유용하게 사용될 수 있을 것으로 생각된다.

Purpose: To investigate the long-term results and complications of orbital wall fracture reconstruction using the bioabsorbable orbital implant, Macroporeⓡ orbital floor liner.

Methods: This retrospective study included patients who underwent the reconstruction of an orbital wall fracture using Macroporeⓡ orbital floor liner and completed a postoperative follow-up longer than 6 months. The enophthalmic values as well as the data of ocular movement and diplopia was collected from the medical records of each patient and analyzed.

Results: A total of 35 patients were evaluated with an average follow-up period of 14.0 months. The average enophthalmic value of 29 patients, whose reconstruction was primarily indicated from enophthalmic tissue, was 0.90 mm at the last follow-up. No significant progression of enophthalmos was observed at postoperative 12, 18 and 24 months when compared with the enophthalmic value at postoperative 6 months. All 15 patients who have had the limitation of ocular movement or diplopia preoperatively resolved completely or improved to the degree that no clinically significant limitation or diplopia further existed. No complications such as dislocation of implant, infection, and aggravation of ocular limitation were observed during the follow-up period.

Conclusions: Macroporeⓡ orbital floor liner may be regarded as a useful implant in reconstruction of orbital wall fracture with no significant implant-related complications during its absorption.
