Purpose:
To study the cosmetic outcome of external dacryocystorhinostomy (Ex-DCR) and to detect the factors affecting it.
Patients And Methods:
Prospective randomized interventional study included forty patients who were treated by 40 Ex-DCRs. In twenty patients, medial canthal vertical incision was used and in the other twenty cases, subciliary incision was used. The skin was closed using vicryl 6-0 or prolene 6-0 interrupted sutures, and each one was randomly used in twenty patients (10 patients of each incision type). Cosmetic outcome was evaluated 6 months postoperative by the patients and by an oculoplastic surgeon on a four grades scale. Cosmetic results and its correlation to patients' age, sex, skin complexion, type of incision, and type of skin sutures were studied.
Results:
The mean scar grading was 0.98 ± 1.0 and 1.3 ± 1.0 in patients' and examiner's assessment. About 27.5% described their scars as cosmetically significant. The cosmetic outcome was significantly affected by the type of incision with only 5% significant scars in subciliary incision group. Prolene 6-0 suture was associated with better cosmetic results with 15% significant scars. 50% of dark-skinned patients showed cosmetically significant scars. Although no correlation was found between patients' age and cosmetic outcome, pediatric patients showed higher tendency to scar visibility with mean scar grade 1.2 ± 1.0 and 1.5 ± 0.9 in patients' and examiner's assessment.
Conclusion:
Dark skinned and pediatric patients are more prone to visible Ex-DCR scar. The use of subciliary approach and prolene 6-0 skin sutures is associated with more favorable cosmetic outcome.
