Abstract Bell’s palsy in pregnancy and immediate puerperium is a rare complication, has worse prognosis. Certain physiological changes predispose to Bell’s Palsy like Pre-eclampsia, Raised cortisol levels, Hypercoagulable state and Impaired sugar levels. Management of Bell’s Palsy in these patients is challenging. Efficacy of corticosteroids in facial palsy is proven, however, their use in pregnancy is controversial. This article reviews management of Bell’s Palsy in pregnancy. Key Word: Bell’s Palsy, Corticosteroids, Physiological Changes, Pregnancy
INTRODUCTION Bell’s palsy in pregnancy is a rare but debilating illness. Hilsinger et al determined a frequency of Bell’s Palsy in pregnant women at 45.1 per 100,000 births per year, compared to a non-pregnant incidence of 17.4 for the same age group. Physiological Changes In Pregnancy That Predispose To Facial Nerve Palsy Ashen et al, Shapiro et al, Vrabec et al, Osterman et al reported physiological changes in pregnancy that predispose to facial nerve palsy:
TREATMENT Facial nerve palsy can be managed medically as well as surgically. Medical management comprises of eye care, corticosteroids, antivirals. Ophthalmic Management Includes: for corneal protection
Corticosteroids: Ashen et al concluded that use of corticosteroids in pregnant state is controversial. Corticosteroids are effective in improving recovery and limiting progression of facial palsy. Edwards et al reported safety of corticosteroids for management of many medical conditions during pregnancy like severe asthma, rheumatological and dermatological conditions, prevention of respiratory distress syndromes for at risk pregnancies. Ahsen et al, Katie et al, Wyllie et al reported adverse perinatal outcomes associated with use of systemic corticosteroids in pregnancy. These are adrenal suppression, preterm birth, low birth weight, cleft lip, cleft palate. Ahsen et al also reported maternal side effects-increased infections, peptic ulcers, exacerbation of diabetes, osteoporosis, psychosis, fluid retention. Schafer et al, Kunze et al concluded that breast fed infant is not at risk. Rennick et al reported safety of Prednisone and Methylprednisolone during pregnancy as they are rendered inactive by placental barrier. Dexamethasone and Betamethasone reach fetus in considerable amounts. Dose of prednisolone (Ahsen et al)
Blood pressure, body weight, blood sugar level, enquire regarding new infections, gastrointestinal symptoms, sleep/mood disturbances should be monitored in mother while administering systemic corticosteroids. Fetal monitoring should also be undertaken (Ahsen et al). Pregnancy state with pre-existent uncontrolled diabetes mellitus, hypertension etc are likely to be worsened by corticosteroid treatment (Ahsen et al). Antivirals: Antivirals like acyclovir, valacyclovir, famcyclovir are prescribed in Ramsay Hunt Syndrome. They are not so effective (Ahsen et al, Sullivan et al). Immediate surgical management includes nerve decompression and ophthalmic plastic surgery. Prognosis of bell’s palsy in pregnancy: Sullivan et al reported early treatment with corticosteroid limit aberrant nerve regeneration and permanent paralysis. Hato et al reported pregnancy with complete bell’s palsy has bad prognosis as compared to bell’s palsy in non pregnant state.
