Abstract
ABSTRACT Purpose To disclose that the lacrimal sac is classified within the orbital tissue. Materials and Methods Ten orbits of 9 Japanese cadavers aged 64 to 85 years at death were included. The attachment site of the orbital septum in the medial canthal area was grossly dissected. The relationship between the orbital septum attachment site and the location of the lacrimal sac was examined. Results In the upper region, the orbital septum was attached to the most superior area of the lacrimal fossa and the medial canthal tendon. In the lower region, the septum was attached to the anterior lacrimal crest and the medial canthal tendon. In both the upper and lower regions, none of the septa attached to the posterior lacrimal crest. The lacrimal sac was situated behind the orbital septum. Conclusion The lacrimal sac, which is situated behind the orbital septum, is classified within the orbital tissue.
