PURPOSE:: To report the results of @entity1341 injection into the orbicularis oculi muscle to treat lagophthalmos in @entity1 with long-standing Bell palsy. METHODS:: In this prospective interventional case series, @entity1341 , 5 ml of a 0.750% solution, was injected into the preseptal and pretarsal area of the orbicularis oculi in each of 10 @entity1 with @entity1897 . The measures of vertical eyelid apertures during open and closed eyes were made before the procedure and 1, 3, and 6 months after injection. RESULTS:: A total of 10 eyes including 2 @entity1 and 8 @entity1 with an average age of 43 years (26-64 years) were studied. The mean amount of lagophthalmos before injection and after 6 months of follow up were 3.9 mm and 2.3 mm, respectively (p = 0.01)). The mean amount of corneal exposure before injection and after 6 months of follow up was 1.05 mm and 0.25 mm, respectively (p < 0.01). The mean scleral show in open eyes before injection and after 6 months of follow up were 1.20 mm and 0.75 mm, respectively (p = 0.08). The mean scleral show in closed eyes before injection and after 6 months of follow up were 1.95 mm and 1.15 mm, respectively (p = 0.01). All the @entity1 reported significant @entity9467 . CONCLUSION:: @entity1341 injection in the paretic orbicularis oculi muscle improves eyelid closure and lagophthalmos and @entity9467 .
