Dacryocystoethmoidostomy

Dacryocystoethmoidostomy (dacryocystoethmoidostomia; dacryocysto- + anat. os ethmoidale ethmoid bone + Greek stoma opening) is a surgical operation that involves creating a connection between the lacrimal sac and the nasal cavity through the ethmoid bone. It is performed in case of obstruction of the nasolacrimal duct in order to restore the outflow of tear fluid into the nasopharynx.

Indications for dacryocystoethmoidostomy are chronic dacryocystitis and strictures of the nasolacrimal duct. The operation can be performed using both open and endonasal endoscopic approaches. With open dacryocystoethmoidostomy, a skin incision is made in the area of ​​the inner corner of the eye. After opening the lacrimal sac, an anastomosis is created in the lateral wall of the nasal cavity.

Endoscopic dacryocystoethmoidostomy is performed through the nostril using an endoscope. The advantages of this method are the absence of an external skin incision and better cosmetic results. Both methods allow one to achieve good functional results and facilitate the outflow of tear fluid in pathologies of the lacrimal ducts.
