ABSTRACT
Aim:
To evaluate the efficacy of modified temporalis muscle transfer (TMT) by silicone sling for the management of paralytic lagophthalmos. Settings andDesign:
Prospective interventional study. Materials andMethods:
Ten patients of lagophthalmos due to facial palsy underwent modified TMT using silicone sling. The patients were followed‑up for a period of 3 months. Palpebral aperture in primary gaze and during eye closure were assessed both pre‑ and postoperatively along with problems associated with lagophthalmos like exposure keratopathy and lacrimation. StatisticalAnalysis:
Paired t‑test was applied to measure the statistical outcome.Results:
Eight patients achieved full correction of lagophthalmos with no lid gap on closing the eye. The mean (standard deviation (SD)) lid gap on eye closure was 7.7 (0.86) mm preoperatively, 0.5 (0.47) mm at 1st postoperative day, and 0.7 (0.75) mm at 3rd month. There was a reduction in mean lid gap on eye closure of 7 mm at 3 months (P < 0.0001) which is highly significant. The mean (SD) vertical interpalpebral distance during primary gaze was 12.05 (1.12) mm preoperatively, 10 (0.94) mm at 1st postoperative day, and 10.35 (1.08) mm at 3rd month. There was a reduction in mean vertical inter palpebral distance of 1.7 mm at 3 months (P = 0.001) which is significant. Exposure keratitis decreased in five out of six patients at 3 months.Conclusion:
Modified TMT by silicone sling is a useful procedure with lesser morbidity and good outcomes for the treatment of paralytic lagophthalmos due to long standing facial palsy.
