A prospective randomized study comparing division of the pedicle of modified hughes flaps at two or four weeks.

Abstract

To compare the incidence of upper and lower eyelid malposition or other complications when the pedicle in modified Hughes flap repair of the lower eyelid is divided at 2 versus 4 weeks. A prospective randomized study. Data were collected on patient age and sex, horizontal tumor dimension, upper and lower eyelid position before surgery and 3 months after division of the pedicle, and any complications. Complete data from 60 patients were collected, with 32 patients in the 2-week group and 28 patients in the 4-week group. The two groups were not significantly different in terms of sex, age, or tumor dimensions. In the 2-week group, the upper eyelid was within 1 mm of its preoperative position at 3 months in 25 of 32 patients (78.1%) and in 26 of 28 (92.8%) in the 4-week group. The lower eyelid was within 1 mm of its normal position in 27 of 32 patients in the 2-week group (84.4%) versus 25 of 28 (89.3%) in the 4-week group. Statistical analysis showed no significant difference between the 2- and 4-week groups for upper and lower eyelid position at 3 months. Other complications were uncommon and evenly spread between the two groups. A modified Hughes flap pedicle may be divided at 2 weeks with no increased incidence in upper or lower eyelid malposition or other complication.
