Aim:
To evaluate the effectiveness of transcanalicular multi diode laser in revision dacryocystorhinostomy and to determine the outcomes.
Materials And Methods:
Fifty-three consecutive patients (19 males, 44 females) who were referred for recurrent dacryostenosis with epiphora after a failed primary dacryocystorhinostomy (DCR) operation were included in the study. Patients were assigned to two separate groups on the basis of primary DCR operation: either endonasal dacryocystorhinostomy (END-DCR) or transcanalicular multi diode laser dacryocystorhinostomy (TC-MDL DCR). TC-MDL DCR technique was used for revision surgeries in both groups. The mean age of the patients was 46.5 ± 13.1 (Range, 15 -71) and the average follow-up duration was 12 months.
Results:
The success rate was 62% (18/29) in the primarily TC-MDL DCR operated group, and 85.2% (29/34) in the primarily END-DCR operated group respectively. The occlusion of internal ostium with granulation tissue was the leading etiology of unsuccessful surgical outcome in both group 1 and group 2 (42.8% and 28.5% respectively).
Conclusions:
TC-MDL DCR is a minimally invasive surgical method with relatively high success and low complication rates in patients with failed primary DCR requiring revision.
