Younger surgeons increasingly prefer endoscopic dacryocystorhinostomy (DCR) over external approaches, while most surgeons find preoperative imaging has low relevance for DCR procedures.
Area of Science:
- Ophthalmology
- Oculoplastics
- Rhinology
Background:
- Dacryocystorhinostomy (DCR) is a surgical procedure to restore tear drainage.
- Endoscopic DCR (endoDCR) and external DCR are the primary surgical approaches.
- Practice patterns and influencing factors for DCR techniques are not fully elucidated.
Purpose of the Study:
- To survey American Society of Ophthalmic Plastic and Reconstructive Surgery members on current DCR practice patterns.
- To identify factors influencing the choice between endoscopic and external DCR.
- To assess the use and perceived relevance of preoperative imaging in DCR.
Main Methods:
- A cross-sectional, anonymous 16-question web-based survey was distributed to 277 members.
- Survey assessed surgeon demographics, practice settings, surgical preferences, and imaging practices.
- Responses were statistically analyzed for frequency distributions and comparisons.
Main Results:
- 111 surgeons (40.0%) responded, showing variable endoDCR utilization.
- Junior surgeons (<5 years) were more likely to use endoDCR (>66% of cases) than senior surgeons (>15 years).
- Academic surgeons utilized endoDCR more than private practice surgeons; scar avoidance and revision were key endoDCR reasons.
Conclusions:
- EndoDCR utilization correlates with years in practice, favoring younger surgeons.
- A majority of surgeons perceive low relevance for preoperative imaging in most DCR cases.
- Further research is needed to standardize indications for endoDCR vs. external DCR and imaging.
