Purpose: To evaluate the surgical outcomes of pediatric congenital blepharoptosis with poor Bell’s phenomenon (BP) treated with modified levator muscle complex suspension.Methods: Forty-two pediatric congenital blepharoptosis patients with poor BP were treated with modified levator muscle complex suspension, and their major surgical outcomes such as marginal reflex distance1 (MRD1), palpebral fissure height (PFH), and postoperative lagophthalmos were retrospectively reviewed. Results: The mean follow-up was 10.28±9.89 months (range: 3-32 Months). Surgical success was achieved in 54 (87.1%) of 62 eyelids at the final visit, including excellent results in 46 (74.2%) eyelids, good results in 8 (12.9%) eyelids, and poor results in 8 (12.9%) eyelids, respectively. The postoperative PFH of affected eyes (7.97±1.47 mm) was significantly improved compared with that before surgery (3.58±1.31 mm). The mean MRD1 was improved from -1.48±1.36 mm before surgery to 2.94±1.46 mm after surgery. The postoperative MRD1 was ≥ 3 mm in 46 eyelids and < 3 mm in 16 eyelids. The mean lagophthalmos was 1.42±1.20 mm 3 months after surgery. All of the patients presented complete blink postoperatively. Postoperative complications were rarely observed during follow-up. No patient had exposure keratitis, but blepharoptosis recurred in 6 patients (8 eyelids). All patients had satisfactory eyelid symmetry and contour. No complications were observed until the last visit.Conclusions: The modified method results complete blink, mild and quick recovery of lagophthalmos, flexible eyelid motility, stable ocular surface, and it is simple to perform with few complications and a low recurrence rate at 12.9%, which is worth to wide application on poor bell’s phenomenon blepharoptosis. |
