Congenital nasolacrimal duct cyst (NLDC) is a rare disorder, which can present with ophthalmological and nasal signs and symptoms. The authors analyse their personal experience to identify diagnostic criteria for NLDC, which were treated by endoscopic transnasal procedure. Methods. Clinical records of patients with a diagnosis of NLDC were retrospectively re- viewed. All patients underwent rhinoscopy and ophthalmologist evaluation before surgery, whereas imaging was performed in selected cases. All neonates underwent transnasal endo- scopic marsupialisation after failure of conservative medical therapy. Results. Five patients were included in the study. One patient presented bilateral NLDC. In Received: March 23, 2020 3 cases, CT scan of the sinus was carried out. A total of 6 marsupialisation procedures were Accepted: May 21, 2020 performed and a bi-canalicular lacrimal stent was positioned in 1 case. Complete remission of symptoms was observed in all cases. Correspondence Conclusions. Nasal endoscopy is mandatory to diagnose NLDCs, and, in some cases, it can Vittorio Rampinelli be complemented by radiological procedures. When symptoms persist after systemic and Unit of Otorhinolaryngology-Head and Neck topical therapy, nasal endoscopic marsupialisation is the treatment of choice.
