영문 초록

Purpose: This study investigated the anatomy of the anterior ethmoidal foramen, posterior ethmoidal foramen, optic foramen, and nasolacrimal duct located in the medial orbit. Methods: The subjects of this investigation were 20 eyes of 10 cadavers, three were male and seven were female. After exenteration, anatomic evaluation of medial orbit and nasolacrimal duct were performed. The results were verified by Mann-Whitney U test. Results: The distance from the posterior lacrimal crest is 16.10±1.07 mm to the anterior ethmoidal foramen, 30.35±4.08 mm to the posterior ethmoidal foramen and 37.40±2.03 mm to the optic foramen. The distance is 13.95±1.16 mm between the anterior and posterior ethmoidal foramen, 6.45±1.86 mm between the posterior ethmoidal foramen and optic foramen. The distance from the anterior ethmoidal foramen to its vertical contact point from the anterior ethmoidal foramen to the base line between the posterior lacrimal crest and optic foramen is 14.68±2.56 mm, from This vertical contact point to the posterior lacrimal crest is 4.00±1.35 mm and the angle between line from the anterior ethmoidal foramen to the posterior lacrimal crest and the line from the optic foramen to the posterior lacrimal crest is 16.15±7.03. The distance from the posterior ethmoidal foramen to its vertical contact point from the posterior ethmoidal foramen to the base line between the posterior lacrimal crest and optic foramen is 30.88±2.27 mm, from this vertical contact point to the posterior lacrimal crest is 2.30±0.71 mm and the angle between the line from the posterior ethmoidal foramen to the posterior lacrimal crest and the line from the optic foramen to the posterior lacrimal crest is 4.43±1.47. The total length is 33.55±5.34mm, the angle are 44.98±6.61° between the coronal plane and 36.60±2.19°between the sagittal palne in nasolacrimal duct. Conclusions: Our study evaluate normal anatomy of the medial orbit, suggest surgical index in Korean.
