Dacryocystorhinostomy – technique of endonasal microsurgery

Introduction: Nasolacrimal duct obstruction can be due to ophthalmologic or laryngologic causes. Therapy of this condition is dacryocystorhinostomy (DCR) – with standard, external approach or using intranasal procedures.
Aim: This study presents the operational technique and the results of intranasal operations of reopening the nasolacrimal drainage system.
Materials: Two patients were operated on. The first one had postinflammatory changes, while in the second case the reason for the obstruction was trauma of the facial skeleton.
Method: The technique of operation is based on exposure of the lacrimal sac to the level of conchae mediae, its opening and inserting the small drains for six weeks.
Outcomes: In both cases, immediate symptom regression as well as good final result after drain removal was observed. As the literature confirms, intranasal technique is as effective as those with access from outside, but an extremely significant matter for the patient is the lack of a scar on the face after the intranasal procedure.
Conclusions: Dacryocystorhinostomy is an optional surgical technique of intranasal surgery. It allows the extent of the operation to be reduced. It can be carried out by clinics that are experienced in endoscopic and microscopic rhinosurgery.
