목적: 한국인 사체해부와 전산화 단층촬영을 이용하여 깊은 안와 외벽의 수술적 해부구조를 연구하고자 하였다. . 대상과 방법: 깊은 안와 외벽 감압술의 수술적 지표가 되는 안와 외벽 지표간 거리를 사체 12구 24에 대한 외과적 해부와 정상 성인20명 40안에서 시행한 전산화 단층촬영을 이용하여 측정하였으며, 두 군 간 중복이 되는 지표 거리를 통계적으로 비교 분석하였다. 결과: 사체연구를 통해 측정된 위 안와 틈새 끝과 이마 나비뼈 봉합선에서 가쪽 안와 가장자리까지의 거리는 36.7 ± 1.98 mm, 18.2 ± 1.92 mm 이며 위 안와 틈새 끝에서 아래 안와 틈새까지의 수평거리는 17.1 ± 1.19 mm이다. 전산화 단층촬영을 이용하여 측정한 위 안와 틈새끝과 이마 나비뼈 봉합선에서 가쪽 안와 가장자리까지의 거리는 39.2 ± 2.46 mm, 17.8 ± 1.56 mm이다. 결론: 사체연구와 전산화 단층촬영 연구를 통하여 측
Abstract
Purpose: We investigated the surgical anatomy of the deep lateral orbital wall via dissection of Korean cadavers and analysis of the orbit in normal adults using computed tomography. Methods: Twelve cadavers were used to determine the exact anatomic index of the orbital lateral wall, and computed tomography images of 20 patients were used for surgical anatomic measurements during deep lateral orbital wall decompression. Additionally, the anatomic indexes measured in the cadavers and in the computed tomography study were compared and analyzed. Results: In the cadaver study, the mean distance from the orbital rim to the end of the superior orbital fissure was 36.7 ±1.98 mm, to the rim of the frontosphendoial suture was 18.2 ± 1.92 mm, and from the end of the superior orbital fissure to the inferior orbital fissure was 17.1 ± 1.19 mm. In the computed tomography study, the mean value from the orbital rim to the end of the superior orbital fissure was 39.2 ± 2.46 mm, and from the rim to the frontosphenoidal suture was 17.8 ± 1.56 mm. Conclusions: The present study regarding the surgical index of the lateral orbital wall in Koreans will assist surgeons to safely and confidently perform deep lateral orbital wall decompression.
