What surgical procedure is referred to as dacryocystotomy?

Dacryocystotomy is a surgical procedure specifically targeting the lacrimal sac, which is a key component of the tear drainage system in the eye. This procedure involves making an incision into the lacrimal sac to relieve blockages or to facilitate the drainage of tears. It is often performed in cases where there is an obstruction causing excessive tearing or infection in the lacrimal system.

Understanding the significance of this procedure highlights its focused anatomical involvement; thus, it is crucial for addressing conditions specifically related to tear drainage. The other options pertain to different anatomical areas and procedures that do not relate to the lacrimal system, helping to clarify that the primary intention behind dacryocystotomy is associated with the treatment of the lacrimal sac and the surrounding structures involved in tear production and drainage.
