In Dacryocystorhinostomy, opening is done into which of the following pa of the nose?

Dacryocystorhinostomy is a surgical procedure performed to assist in the drainage of tears and secretions from the lacrimal sac into the middle meatus of the nose by forming a sho circuit through the lacrimal bone and the nasal mucosa. This procedure is performed when the nasolacrimal duct is obstructed by fibrous tissue or bone and has become impermeable in order to establish a new communication pathway between lacrimal sac and nose.
