Purpose:
|
Purpose: To report the results of bupivacaine injection into the orbicularis oculi muscle to treat lagophthalmos in patients with long standing Bell’s palsy.
|
|
Methods:
|
In this prospective interventional case series, bupivacaine, 5 ml of a 0.750% solution, was injected into the pre-septal and pre-tarsal area of the orbicularis oculi in each of 10 idiopathic peripheral facial nerve palsy patients. 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 men and 8 women with an average age of 43 (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) (Figure 1). 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) (Figure 2). 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).

|
Conclusion:
|
Bupivacaine injection in the paretic orbicularis oculi muscle improves eyelid closure and lagophthalmos and epiphora.
