Endonasal Dacryocystorhinostomy: Results With or Without Stenting

Area of Science:

• Ophthalmology
• Otorhinolaryngology

Background:

• Chronic dacryocystitis results from nasolacrimal duct obstruction.
• Endonasal dacryocystorhinostomy (DCR) is a surgical treatment for this condition.
• The use of silicon stents during endonasal DCR is debated.

Purpose of the Study:

• To compare the curative outcomes of endonasal DCR with and without silicon stent placement.
• To evaluate the efficacy of stenting in patients with chronic dacryocystitis.

Main Methods:

• A comparative cross-sectional study involving 60 adult patients with chronic dacryocystitis.
• Patients underwent endonasal DCR, with 30 receiving a silicone stent and 30 not receiving one.
• Outcomes were assessed over a 12-month follow-up period using Chi-square tests.

Main Results:

• Success rates at 6 months were 90% (stented) and 93.3% (non-stented) (p=0.64).
• Success rates at 12 months were 80% (stented) and 76.6% (non-stented) (p=0.71).
• Patent rhinostomy openings at 12 months were 93.3% (stented) and 90% (non-stented).

Conclusions:

• Endonasal DCR with and without silicon stents yielded comparable results for chronic dacryocystitis.
• No significant difference in outcomes was observed between the stented and non-stented groups.
• Silicon stents may be reserved for specific cases like revision surgeries or sinonasal pathology.
