The predictive value of nasolacrimal sac biopsy in endoscopic dacryocystorhinostomy.

ABSTRACT:

Background

During dacryocystorhinostomy (DCR), the lacrimal sac wall biopsy is not routinely performed in our hospital, but it is recommended if there is a suspicion of underlying disease other than preoperatively or intraoperatively chronic inflammation.

Objective

Most of patients with epiphora have different causes of nasolacrimal duct obstruction (NLDO). This study aims to examine how important routine lacrimal sac biopsy is during endoscopic DCR surgery.

Patients & methods

The study included 50 patients with chronic unilateral epiphora. All patients underwent endoscopic DCR with NLD biopsy. Histopathologic analysis was performed for each specimen.

Results

The findings of NLD biopsy showed chronic inflammation in 33 cases (66%), chronic dacryocystitis in 9 c
