Summary

Conjunctivo-dacryocystorhinostomy uses a Jones tube to restore tear flow in obstructed cases. This technique was adapted for a patient lacking a nasal structure, demonstrating its versatility.

Area of Science:

Ophthalmology
Otorhinolaryngology

Background:

Epiphora, or excessive tearing, often results from blocked tear drainage pathways (canaliculiculi).
Conjunctivo-dacryocystorhinostomy (CDCR) with a Jones tube is a standard surgical procedure to bypass these obstructions and restore tear flow into the nasal cavity.

Observation:

The standard Jones tube connects the conjunctival sac to the nasal mucosa.
A unique case involved a patient with epiphora and a complete absence of the nose, precluding standard nasal intubation.

Findings:

An extended Jones tube was successfully utilized in a patient without a nose to manage epiphora.
This modification allowed for the creation of a functional tear drainage pathway, bypassing the nasal obstruction.

Implications:

The findings suggest that CDCR with modified Jones tubes can be adapted for complex anatomical variations.
This technique offers a viable solution for epiphora in patients with nasal absence or significant nasal deformities.
