Intradermal suture post-surgical scar in external dacryocystorhinostomy: technique and patient satisfaction survey

Abstract

Purpose: Dacryocystorhinostomy surgery may result in significant postoperative scarring. Although other surgical techniques have been developed that achieve a better aesthetic result, the ab externo technique remains the gold standard for this procedure. We developed a telephone survey to evaluate the visual impact of postoperative skin scars associated with ab externo dacryocystorhinostomy. Methods: 470 patients underwent uncomplicated external dacryocystorhinostomy surgery by two consultant surgeons from January 2014 to December 2021. Skin incisions were closed using intradermic continuous suture with prolene 6.0. The exclusion criteria were cases of dacryo-phlegmon and lacrimal sac fistulae with skin maceration. The visual effect of the postoperative scar was evaluated, and the degree of patient satisfaction was measured by a questionnaire with four subjective perceptions of the scar (very good, good, bad, very bad) given by a physician in the first postoperative month. The survey responses were used as the basis for a literature review. Results: The survey received 470 responses (100%) Very good perception of the scar was achieved in 75,8% of patients. There were no other post-operative complications noted from medical records review. Conclusions: Given the small percentage of patients who complained of marked scarring, it should not be the main reason for deciding on the procedure for dacryocystorhinostomy, especially in elderly patients. Therefore, the surgical technique should be considered as a surgically acceptable choice if cosmetic results were selection criteria in the case of total stenosis of the nasolacrimal duct.
