Summary
Endoscopic sinus surgery can cause nasolacrimal duct obstruction, a previously unreported complication. Dacryocystorhinostomy was required for eight patients to restore normal tear drainage after this procedure.
Area of Science:
- Ophthalmology
- Otolaryngology
- Surgical Anatomy
Background:
- Intranasal endoscopic sinus surgery (ESS) is increasingly common.
- ESS carries potential ocular complications, including visual loss and diplopia.
- Nasolacrimal duct obstruction (NLDO) is a newly reported complication of ESS.
Purpose of the Study:
- To report persistent nasolacrimal duct obstruction (NLDO) as a complication of endoscopic sinus surgery (ESS).
- To discuss the management of iatrogenic NLDO following ESS.
- To review the relevant anatomy and preventative surgical strategies.
Main Methods:
- Case series of eight patients with persistent NLDO post-ESS.
- Surgical intervention with dacryocystorhinostomy (DCR) to restore lacrimal drainage.
- Review of nasolacrimal duct anatomy and iatrogenic injury prevention.
Main Results:
- All eight patients presented with persistent NLDO after ESS.
- All patients successfully treated with dacryocystorhinostomy (DCR).
- This complication appears to be previously unreported in ophthalmologic literature.
Conclusions:
- Persistent nasolacrimal duct obstruction is a potential complication of endoscopic sinus surgery.
- Dacryocystorhinostomy is an effective treatment for iatrogenic NLDO post-ESS.
- Anticipate increased ocular complications, including NLDO, with rising ESS prevalence.
