Sponsor's own description

During dacryocystorhinostomy (DCR), the lacrimal sac wall biopsy is not routinely performed, but it is recommended if there is a suspicion of underlying disease other than preoperatively or intraoperatively chronic inflammation. We aimed to evaluate the utility of the histopathology examination of fifty patients in AlAzhar Hospitals to put recommendation for histopathology examination of such cases.
