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.
Clinical records of patients with a diagnosis of NLDC were retrospectively reviewed. All patients underwent rhinoscopy and ophthalmologist evaluation before surgery, whereas imaging was performed in selected cases. All neonates underwent transnasal endoscopic marsupialisation after failure of conservative medical therapy.
Five patients were included in the study. One patient presented bilateral NLDC. In 3 cases, CT scan of the sinus was carried out. A total of 6 marsupialisation procedures were performed and a bi-canalicular lacrimal stent was positioned in 1 case. Complete remission of symptoms was observed in all cases.
Nasal endoscopy is mandatory to diagnose NLDCs, and, in some cases, it can be complemented by radiological procedures. When symptoms persist after systemic and topical therapy, nasal endoscopic marsupialisation is the treatment of choice. This surgical procedure is effective, safe and can be repeated if needed.
先天性鼻泪管囊肿（NLDC）是一种罕见疾病，可出现眼部和鼻部体征和症状。作者分析其个人经验，以确定 NLDC 的诊断标准，并采用经鼻内镜手术进行治疗。
回顾性分析诊断为 NLDC 的患者的临床记录。所有患者均在手术前接受鼻内镜和眼科医生评估，而选择性病例则进行影像学检查。所有新生儿在保守药物治疗失败后均接受经鼻内镜造袋术。
本研究纳入 5 例患者。1 例患者表现为双侧 NLDC。3 例患者进行了鼻窦 CT 扫描。共进行了 6 次造袋术，1 例患者同时放置了双泪小管泪道支架。所有患者的症状均完全缓解。
鼻内镜检查对于 NLDC 的诊断至关重要，在某些情况下，还可以结合影像学检查。在全身和局部治疗后症状持续存在时，经鼻内镜造袋术是首选治疗方法。该手术有效、安全，如果需要，可重复进行。
