dacryocystorhinostomialla

Dacryocystorhinostomialla is not a standard medical term and appears to be a misspelling or nonstandard variant of dacryocystorhinostomy (DCR). Dacrystocystorhinostomy, commonly abbreviated DCR, is a surgical procedure that creates a direct passage between the lacrimal sac and the nasal cavity to bypass obstruction of the nasolacrimal duct and relieve tear overflow (epiphora).

The procedure addresses acquired nasolacrimal duct obstruction or chronic dacryocystitis. The lacrimal sac sits near the medial canthus, adjacent to the nasal cavity. In DCR, bone is removed at the lacrimal fossa to create an osteotomy, and the mucosal surfaces of the lacrimal sac and the nasal cavity are sutured together to form a new drainage route. The goal is to restore tear drainage and reduce stagnation that can lead to infection.

There are two main surgical approaches. External DCR uses a skin incision near the medial canthus, with the creation of a bony window and mucosal anastomosis. Endoscopic endonasal DCR is performed through the nasal cavity without an external scar and relies on endoscopic visualization. Both approaches aim for similar patency rates, though success can vary with surgeon experience and etiology. Silicone stents may be placed temporarily to maintain patency in some cases.

Common indications include unresolved epiphora due to nasolacrimal duct obstruction, chronic dacryocystitis, and failed prior probing or intubation. Complications are relatively uncommon but can include bleeding, infection, restenosis, or fistula formation. Postoperative care typically involves nasal irrigation, topical antibiotics, and follow-up to assess drainage and stent status if used.
