Bilateral nasolacrimal duct obstruction (NLDO) patients require significantly more concomitant nasal surgeries during dacryocystorhinostomy (DCR) than unilateral cases. This highlights the importance of evaluating nasal health in bilateral NLDO patients before surgery.
Area of Science:
- Otolaryngology
- Ophthalmology
- Rhinology
Background:
- Primary nasolacrimal duct obstruction (NLDO) etiology is often unknown, with bilateral cases occurring less frequently.
- Dacryocystorhinostomy (DCR) is the standard surgical treatment for NLDO.
- Concomitant nasal pathologies may negatively impact DCR surgical success rates.
Purpose of the Study:
- To retrospectively assess the frequency of concomitant nasal surgical procedures needed for endoscopic DCR.
- To compare the rates of required nasal surgeries in patients with bilateral versus unilateral NLDO.
Main Methods:
- Retrospective analysis of 28 patients undergoing bilateral endoscopic DCR and 30 patients undergoing unilateral endoscopic DCR.
- Recording of all concomitant nasal surgical procedures performed during DCR.
- Analysis of procedure frequencies including septoplasty, turbinectomy, and concha resection.
Main Results:
- A significantly higher rate of concomitant nasal surgery was observed in the bilateral DCR group (78.6%) compared to the unilateral DCR group (26.7%).
- Specific procedures like septoplasty were more frequent in bilateral NLDO patients (57.1%) than unilateral (16.7%).
- Nasal pathologies requiring surgical intervention were more prevalent in patients with bilateral NLDO.
Conclusions:
- Patients with bilateral NLDO exhibit a substantially higher incidence of nasal pathologies requiring surgical intervention during DCR.
- Preoperative assessment of nasal conditions is crucial for optimizing surgical outcomes in NLDO patients, particularly those with bilateral disease.
- Endoscopic DCR in bilateral NLDO often necessitates concurrent nasal procedures, impacting surgical planning and potentially success rates.
