To disclose that the lacrimal sac is classified within the orbital tissue.
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.
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.
The lacrimal sac, which is situated behind the orbital septum, is classified within the orbital tissue.
揭示泪囊属于眶组织范畴。
纳入9具日本尸体的10个眼眶，死者年龄在64至85岁之间。大体解剖内眦区域眶隔的附着部位。检查眶隔附着部位与泪囊位置之间的关系。
在上部区域，眶隔附着于泪囊窝的最上部区域及内眦腱。在下部区域，眶隔附着于泪前嵴及内眦腱。在上部和下部区域，均无眶隔附着于泪后嵴。泪囊位于眶隔后方。
位于眶隔后方的泪囊属于眶组织范畴。
