Surgical creation of an opening between lacrimal sac and nose

• A. Dacryocystorhinostomy
• B. Cystocele
• C. Cytology
• D. Dentist

Answer: (A)

Creating a new drainage passage between the lacrimal sac and the nasal cavity is called a dacryocystorhinostomy. This procedure is done to bypass a blockage in the tear drainage system, typically the nasolacrimal duct, so tears can drain directly from the lacrimal sac into the nose. By establishing this opening, it relieves chronic tearing and reduces the risk of infections that come from tear stasis. The other terms don’t refer to tear drainage surgery—cystocele is a bladder protrusion into the vagina, cytology is the study of cells, and a dentist is a dental professional.
