Summary
Avulsion of the common canaliculus requires prompt diagnosis in deep nasal lacerations or midfacial trauma with telecanthus. Surgical reanastomosis of the lacrimal drainage pathways can effectively treat epiphora.
Area of Science:
- Ophthalmology
- Trauma Surgery
Background:
- The common canaliculus is crucial for tear drainage.
- Avulsion can occur with significant facial trauma.
Purpose of the Study:
- To highlight the clinical signs of common canaliculus avulsion.
- To present a surgical solution for restoring lacrimal drainage.
Main Methods:
- Clinical observation of patients with midfacial trauma.
- Diagnostic assessment including physical examination.
- Surgical intervention: canaliculodacryocystorhinostomy.
Main Results:
- Deep lateral nasal lacerations and traumatic telecanthus are key indicators.
- Blunting of the canalicular angle and inner canthus rounding confirm the injury.
- Successful reanastomosis relieved epiphora.
Conclusions:
- Early suspicion of common canaliculus avulsion is vital in specific trauma scenarios.
- Prompt surgical repair can restore lacrimal drainage and alleviate symptoms.
