Obstetric anesthesia in patients with idiopathic facial paralysis (Bell's palsy): a 10-year survey.

Abstract

During pregnancy there is an increased incidence of idiopathic facial paralysis (Bell's palsy). During a 10-yr period, 36 patients with a diagnosis of pregnancy-associated Bell's palsy were identified retrospectively. Twenty-five patients developed symptoms during the third trimester, whereas the remaining 11 became symptomatic during the first week postpartum. Twenty women delivered vaginally and 16 by cesarean section with a variety of anesthetics being used. Five patients received spinal, 22 epidural, and 3 general anesthetics; 7 patients received no anesthesia. The incidence and distribution of the palsy were similar among patients delivered with and without anesthesia. We conclude that the appropriate anesthetic for a given patient may be chosen without concern for the coexisting Bell's palsy.
