Summary
Nasolacrimal duct obstruction, common in cleft lip and palate surgery, can be addressed with a new anatomical classification and surgical technique. This method transposes the upper punctum and canaliculus to treat epiphora when the lower punctum is damaged.
Area of Science:
- Ophthalmology
- Plastic Surgery
- Anatomy
Background:
- Blockage of the nasolacrimal system is a recognized complication in cleft lip and palate (CF) surgery.
- This obstruction commonly occurs in patients with facial clefts and those with post-traumatic conditions affecting the nasolacrimal passage.
Purpose of the Study:
- To present an anatomical classification of the lacrimal passage system for surgical planning.
- To describe a novel surgical technique for correcting nasolacrimal duct obstruction.
Main Methods:
- Anatomical classification divides the lacrimal passage into four distinct parts, each requiring specific surgical consideration.
- A new surgical technique involves transposing the upper punctum and canaliculus into the lower eyelid.
Main Results:
- The proposed classification aids in tailored surgical planning for nasolacrimal system anomalies.
- The described transposition technique offers a solution for epiphora when the lower punctum is damaged but the upper punctum is functional.
Conclusions:
- A structured anatomical approach is crucial for effective surgical correction of nasolacrimal system blockages.
- The described surgical transposition technique provides a viable option for managing specific cases of epiphora, particularly after trauma or in congenital conditions.
