Summary
Endonasal endoscopic dacryocystorhinostomy is a safe procedure with low complication rates. However, nasal anatomy abnormalities and hemorrhage can present operative difficulties, potentially limiting its indication.
Area of Science:
- Ophthalmology
- Otorhinolaryngology
Context:
- Endonasal endoscopic dacryocystorhinostomy (DCR) is a surgical technique to treat nasolacrimal duct obstruction.
- Assessing operative difficulties is crucial for refining surgical techniques and patient selection.
Purpose:
- To evaluate the frequency of operative difficulties during endonasal endoscopic DCR.
- To identify common challenges and propose solutions for improved surgical outcomes.
Summary:
- A retrospective review of 268 endonasal endoscopic DCR procedures in 241 patients identified operative difficulties in 13.8% of cases.
- Hemorrhage and nasal anatomical variations (e.g., septal deviation, polyps) were the most frequent causes of surgical challenges.
- Complications occurred in 1.9% of cases, including epistaxis and subcutaneous emphysema.
Impact:
- Endonasal endoscopic DCR is generally safe with minimal complications.
- Nasal anatomical alterations may necessitate correction prior to or during surgery.
- Hemorrhage and limited nasal space can increase technical difficulty, impacting procedure feasibility.
