Postoperative evaluation of skin incision in external dacryocystorhinostomy

To evaluate the appearance of the skin incision in external dacryocystorhinostomy 6 weeks and 6 months after surgery.

A prospective, interventional, noncomparative case series of consecutive cases of external dacryocystorhinostomy was performed by 3 surgeons. At 6 weeks and 6 months after surgery, patients were asked to grade their incision, and standardized photographs were evaluated by 3 blinded observers.

Thirty-four consecutive patients were admitted and followed for 6 months. Six weeks after surgery, 9 of 34 patients could not see their incision site (26%), 13 of 34 graded it as minimally visible (38%), 9 of 34 (26%) graded it as moderately visible, and 3 of 34 patients (9%) graded it as very visible (grade 3). Two of 34 patients (6%) were not satisfied with the appearance of the incision. Six months after surgery, 15 of 34 patients (44%) could not see their incision site (grade 0), 16 of 34 (47%) graded it as minimally visible, 3 of 34 patients (9%) graded it as moderately visible, and no patient graded it as very visible. All patients were satisfied with the appearance of their incision. Photographic evaluation of patients 6 weeks after surgery by the 3 observers showed an average score of 1.12, 1.18, and 1.24. There was not a statistically significant difference between the observers (p = 0.95). At 6 months after surgery, the average scores were 0.56, 0.74, and 0.79. There was not a statistically significant difference between the observers (p = 0.43). The change in appearance of the incision at 6 weeks and at 6 months was statistically significant (p < 0.044), as evaluated by patients and observers (p < 0.001).

The skin incision in external dacryocystorhinostomy is satisfactory to most patients. Its appearance is improved with time; 86% of the incisions were graded invisible or minimally visible by observers and 91% by patients after 6 months.
