Exclusive or combined endoscopic approach to tumours of the lower lacrimal pathway: review of the literature

A literature review was conducted to assess the role of minimally-invasive endoscopic treat-ments for lacrimal pathway neoplasms. The study involved the analysis of 316 patients with benign or malignant tumours affecting the lacrimal drainage system. Histologically, the analysis revealed a prevalence of squamous cell carcinoma, followed by lymphatic neo-plasms and melanomas. In terms of treatment, minimally-invasive endoscopic approaches, such as endoscopic dacryocystorhinostomy, play a predominant role in managing early-stage tumours, rather than merely obtaining samples for histological analysis. For more ex-tensive tumours, which constitute the majority of cases, more aggressive external approaches are required, along with the use of adjuvant radiotherapy and chemotherapy. The lack of universally shared staging systems poses a limitation in standardisation and comparison of results. Treatment of these tumours remains complex due to their rarity and histological heterogeneity. A multidisciplinary approach is mandatory to optimise outcomes.
