ENDOSCOPIC DACRYOCYSTORHINOSTOMY

Abstract

SUMMARY. Dacryocystitis is a pathological process which occurs in the lacrimal sac due to obstruction of the lacrimal canal. Today, endoscopic dacryocystorhinostomy is an effective method of treating this disease. In the case of concomitant diseases of the nose, the operation allows not only to ensure effective drainage of the lacrimal sac, but also to restore the functional anatomy of the intranasal structures, which improves the efficiency of treatment. Minimal invasivity, absence of external cosmetic defects, reduction of time that needed for patients recovery, elimination of concomitant defects of intranasal structures and better visualization of the surgical field – are the advantages of the endoscopic technique of surgical treatment.

The aim – to increase the efficiency of surgical treatment of chronic dacryocystitis with the use of ventilation T-tube in the lumen of the nasolacrimal canal in order to ensure the formation of a stable drainage opening into the nasal cavity and prevent its cicatrization and stenosis.

Matherial and Methods. We present our own clinical observation: a 69 year old female with complaints of redness of the left eye and intense tearing.

Results. On the third day after the surgical treatment, redness and swelling of the conjunctiva of the eye decreased due to the restoration of passability of the nasolacrimal duct. At the control examination after 5 months, the patient had no complaints, during endoscopic examination – tear entered into the nasal cavity through dacryocystorhinostoma (functional nasolacrimal duct opening).

Conclusions. Endoscopic dacryocystorhinostomy gives an opportunity to provide a stable drainage effect of the lacrimal sac with minimal invasivity, which significantly improves the efficiency of this surgical treatment. The use of a ventilation T-tube facilitate the formation of a functional nasolacrimal duct opening and prevents its secondary stenosis.
