In this retrospective study the authors investigated the functional and cosmetic outcomes of the modified frontalis sling procedure using silicone rods. The study included 17 patients (26 lids) and nine had bilateral surgery. An excellent outcome was defined as alignment within 1mm height. Mean follow-up was 21.7 months (two to 62). At one month follow-up, good lid height was obtained for 12 patients, fair for eight and poor height for six patients. At final follow-up, good lid height was obtained for 11, fair for six and nine poor height. Good / fair height was achieved in 75% undergoing unilateral surgery; 61.6% with bilateral surgery. Complications included three eyes with recurrence, 10 with lid lag, three with exposure keratitis and one with non-pyogenic granuloma. Satisfaction scores were 14.6, 8.2 and 11.8 for appearance, symptoms and consciousness.
