Co-Occurrence and Possible Role of Sinonasal Anomalies in Primary Acquired Nasolacrimal Duct Obstruction

Abstract

Although primary acquired NLD obstruction seems to be an ophthalmologic problem, rhinologic problems have great importance in etiology. Detailed endoscopic examination and preoperative paranasal sinus computed tomography will reveal the possible role of nasal and paranasal structures adjacent to lacrimal sac in etiology of NLD obstruction. This will be effective both on conservative treatment and postoperative success in patients scheduled for surgery.
