Abstract
BACKGROUND: Patients with involutional blepharoptosis sometimes require reoperation because of functional or esthetic reasons after the primary operation. Few studies have analyzed the risk factors for reoperation in such cases.
METHODS: We retrospectively analyzed the cases of 274 patients who underwent levator aponeurosis surgery for bilateral involutional blepharoptosis. We examined the risk factors for reoperation using univariate and multivariate analyses.
RESULTS: Reoperation was performed for 89 of the 274 patients (32.5%). There was no significant difference in the rate of reoperation among surgeons. In the univariate analysis, patients with preoperative asymmetry, defined as a difference of >1 mm in the marginal reflex distance between the right and left sides, showed a significantly higher rate of reoperation (42.7%) than those without asymmetry (28.1%) (p = 0.018). Age, sex, and ptosis severity did not affect the rate of reoperation. The multivariate analysis with a logistic regression showed that preoperative asymmetry was a significant risk factor for reoperation, with an odds ratio of 1.90 (p = 0.019).
CONCLUSION: In involutional blepharoptosis, patients with preoperative asymmetry should be informed of the higher risk of reoperation, and the balance between the right and left sides should be carefully adjusted intraoperatively.
