Wound Dehiscence Following Upper Blepharoplasty: A Review of 2,376 Cases.

ABSTRACT

PURPOSE: There have been limited studies evaluating specifically the incidence of wound dehiscence following isolated upper blepharoplasty. This is a large-scale upper blepharoplasty review to evaluate the rate of wound dehiscence, to assess risk factors, and to analyze management outcomes. METHODS: A retrospective review was performed of all patients who underwent upper blepharoplasty at a single surgery center. All incisions were closed using either 6-0 fast-absorbing plain gut or polypropylene suture in a running fashion, with an additional interrupted suture near the lateral wound edge. Incidence of wound dehiscence was determined and further assessed by patient age (≤67 or >67 years), gender, preexisting medical conditions, smoking history, and suture type. RESULTS: A total of 1,190 patients (2,376 eyelids) met inclusion criteria. In total, there were 34 instances (1.4%) of wound dehiscence in 32 patients at an average 9 days (range, 0-30 days) following surgery. Evaluation of wound dehiscence rates by demographic factors revealed male gender to be a significant predictor of wound dehiscence (p = 0.0062). Age, hypertension, heart disease, and diabetes were not predictors of wound dehiscence. Lifetime smoking history increased risk for wound dehiscence (p < 0.0001). Use of fast-absorbing plain gut suture was also significantly associated with dehiscence, when compared with polypropylene (p = 0.0025). Multivariate analysis revealed male gender and fast-absorbing plain gut suture to be independent risk factors for wound dehiscence. Seventeen eyelids with wound separation were observed for second-intention healing, 1 underwent delayed scar revision. Fourteen eyelids were repaired primarily using suture and 3 with cyanoacrylate surgical skin adhesive. All patients reported satisfaction with their final outcome, and objective final healing was deemed satisfactory. CONCLUSIONS: Wound dehiscence following isolated upper blepharoplasty is rare and associated with male gender and fast-absorbing plain gut suture. Patients with wound separation may be successfully managed with individualized care.
