Purpose
To compare the anatomical and functional outcomes betweenconventional technique (with flap anastomosis, lacrimal flap-nasal flap) andnew surgical technique (without flap anastomosis, lacrimal or nasal flap-subcutaneous tissue) in external dacryocystorhinostomy (DCR).
Methods
27 patients with a total of 30 eyes of acquired nasolacrimal ductobstruction (NLDO) were operated with external DCR (14 eyes hadconventional technique and 16 eyes had flap-subcutaneous tissuetechnique). Regular follow-up settings were done to document the patient’ssubjective improvement, judge ostium patency on lacrimal irrigation, andrecord any complications.
Results
The mean (SD) age of patients was 66.4 (12.7) years, and there wasa predominance of women (20 [74.1%]). The mean (SD) operative time in flap-subcutaneous technique group was shorter at 70.6 (35.7) minutes comparedwith 114.6 (37.4) minutes in flap-flap technique group (P=0.03). Flap-subcutaneous technique group had a higher (92.9%) success rate whencompared with conventional group (87.5%) but there was no significantdifference in both success rates and complications.
Conclusion
The external DCR with flap-subcutaneous tissue technique iseasy to perform, safe, and provides a high success rate comparable to theconventional technique.
