Evulation of Intranasal Anatomy and Pathologies in the Etiopathogenesis and Treatment of Nasolacrimal Duct Obstruction

Abstract

Objective:Patients who underwent endoscopic dacryocystorhinostomy (DCR) operation were analyzed for their nasal obstructive anatomic and pathologic infrastructures.Methods:Thirty two patients with distal lacrimal system pathology who underwent endonasal endoscopic DCR surgery in the Ear Nose and Throat Clinic were examined with endoscopy and their computed tomographies were evaluated for the nasal and paranasal pathologies. These findings were compared with 50 healthy subjects’ physical examination and computed tomography results. During the DCR operation patients were re-evaluated peroperatively for the nasal pathologies to be corrected if necessary.Results:No statistically significant difference was detected for the nasal septal deviation, agger nasi, concha bullosa, osteomeatal complex or ethmoid pathologies.Conclusion:The relation of the etiopathogenesis of the disease and nasal variations were evaluated because of the close proximity of the nasolacrimal system with the intranasal variations, but there was no statistical connection between them. During the endoscopic endonasal DSR operation obstructive nasal pathologies should be corrected in the same session if necessary.
