Summary
Microsurgery advances enable a new endonasal approach for lacrimal sac issues. This technique, applied in 20 cases, shows high success rates for treating lacrimal duct obstructions.
Area of Science:
- Ophthalmology
- Otorhinolaryngology
Background:
- The endonasal approach to the lacrimal sac is being re-evaluated due to progress in microsurgery.
- The lacrimal duct's anatomical location within the orbito-nasal septum and its visibility in the anterior middle meatus are key surgical considerations.
Observation:
- A specific surgical technique for the endonasal approach was applied to 20 patients.
- The lacrimal duct was successfully visualized and accessed via the anterior middle meatus.
Findings:
- The described endonasal technique achieved successful outcomes in 17 out of 20 cases.
- One case resulted in complete failure, and two cases experienced temporary failures, both successfully re-operated.
Implications:
- This reappraisal suggests the endonasal approach is a viable option for lacrimal sac surgery.
- Further refinement of the technique may improve success rates and reduce the need for revision surgeries.
