Overview
Canalicular adenoma is a benign neoplasm arising from the epithelial lining of the lacrimal canaliculus, often presenting as a slow-growing mass near the eyelid margin 1.Diagnosis
Clinical examination revealing a palpable mass near the punctum 1.
Dye disappearance test may show abnormalities in tear drainage 2.
Imaging (e.g., ultrasound, MRI) can help assess extent and involvement 1.Management
Surgical excision is the primary treatment, aiming for complete removal to prevent recurrence 1.
Adjunctive use of monocanalicular stents in cases involving canalicular repair to maintain patency 23.
Pigtail probe technique facilitates identification and intubation of injured canaliculi, particularly in pediatric patients 23.Special Populations
Pediatrics: Pigtail probe and self-threading monocanalicular stents offer effective and less invasive repair methods 2.
Comorbidities: Specific management adjustments for comorbidities are not detailed in the provided abstracts 1.Key Recommendations
Surgical excision should be performed for definitive treatment of canalicular adenoma (Evidence: Moderate 1).
Use of monocanalicular stents can be considered for maintaining canalicular patency post-repair (Evidence: Weak 23).
In pediatric cases, employing the pigtail probe technique aids in successful canalicular intubation and repair (Evidence: Weak 2).References
