BackgroundDacryolith-induced epiphora is caused by a chronic obstruction of the nasolacrimal duct whose aetiology is often specified peroperatively. Dacryocystorhinostomy (DCR) has been often regarded as the gold standard to treat dacryolithiasis. Hasner’s valve (HV) incision is a technique to evacuate lithiasis through its physiological track. The purpose of this study was to describe clinical and radiological findings associated with presence of dacryoliths in patients who underwent surgery and to assess the efficacy of these two procedures.MethodsThis study was a comparative interventional multicentric retrospective study including patients referred for an epiphora. The primary endpoint was to determine clinical and endoscopic findings associated with dacryoliths. The secondary endpoints were to evaluate the performance of CT dacryocystography (CT-DG) in the diagnosis of dacryoliths and the success rate of the surgical treatment 6 months postoperatively.Results4677 nasolacrimal ducts (NLDs) (78.0% female, mean age 59.2) were included in the study. 3913 underwent DCR, and 764 underwent HV incision. 291 out of 4677 NLDs (6.2%) were found to have dacryoliths. Presence of mucocele associated to a permeable lacrimal system (OR 8.17 (95% 4.62 to 14.44), p<0.01) was associated with presence of lithiasis peroperatively. Success rates at 6 months were 95.6% for endonasal DCR and 94.6% for incision of HV in dacryolithiasis group (p<0.01). CT-DG had a negative predictive value of 96.3% to detect lithiasis (p<0.01).ConclusionStrong clinical and endoscopic findings may improve the imputability of dacryoliths in epiphora. Evacuation of dacryolithiasis through its physiological track was first described in this study in adults with similar results to DCR in patients presenting with dacryolithiasis.

Purpose This prospective study was designed to establish whether it is more effective to treat symptomatic congenital nasolacrimal duct obstruction by probing, or high-pressure irrigation, or both. Methods During the period February 1991 to January 1999, 228 infants (300 nasolacrimal ducts) were examined (132 males, 96 females, age range 12–13 months). These patients were divided into three groups of 100 ducts each. The first group was probed only; in the second group the nasolacrimal ducts were irrigated under high pressure using methylene blue-stained saline, and the third group was probed and irrigated in the same setting. The procedures were done under light general anesthesia. Results Ninety-one ducts in the first group improved after probing. In the second group 64 ducts improved after irrigation. In the third group 96 ducts improved after both probing and irrigation. Conclusions To treat symptomatic congenital nasolacrimal duct obstruction, it is more effective to combine high-pressure irrigation and probing. This gives a better success rate, first in treatment and secondarily, permitting intraoperative verification of the patency of the excretory lacrimal system.
