Current concepts in lacrimal drainage surgery.

Area of Science:

• Ophthalmology
• Otorhinolaryngology

Background:

• Dacryocystorhinostomy (DCR) is the primary treatment for acquired nasolacrimal duct obstruction.
• The endoscope has revived interest in intranasal DCR, challenging the traditional external approach.
• Controversy exists regarding the optimal timing for treating congenital nasolacrimal duct obstruction.

Purpose of the Study:

• To review the current landscape of lacrimal drainage surgery.
• To compare the efficacy and approaches of intranasal versus external DCR.
• To discuss the management strategies for congenital nasolacrimal duct obstruction.

Main Methods:

• Review of current literature and clinical outcome analyses.
• Comparison of results from intranasal and external dacryocystorhinostomy.
• Analysis of cost-effectiveness and decision-making factors in lacrimal obstruction treatment.

Main Results:

• Intranasal DCR is gaining traction, leading to comparisons with the established external approach.
• Early office-based lacrimal probing appears more cost-effective for congenital obstruction.
• Surgical outcomes for pediatric DCR in congenital obstruction are comparable to adult acquired obstruction when performed by experienced surgeons.

Conclusions:

• The choice between intranasal and external DCR involves ongoing debate and depends on surgeon expertise and patient factors.
• Early intervention for congenital nasolacrimal duct obstruction is generally favored, with cost-effectiveness considerations.
• Experienced surgical management ensures comparable outcomes for DCR in both pediatric and adult populations.
