Concurrent facial nerve palsy and uvula deviation after paediatric dental rehabilitation–A case report

Abstract

Introduction Facial nerve palsy is a rare, but known complication resulting from local anaesthesia (LA) infiltration during dental surgery. Its incidence is reported to be 1–1.1%, with short or long-term effects. Case Report A 6 years old well child underwent elective dental rehabilitation under general anaesthesia. For extractions, he received LA infiltration to the anterior part of the hard palate. In the immediate post-operative period, he presented with left sided facial droop and uvula deviation to the left with no hoarseness of voice or ptosis. His neurological symptoms resolved within 3 h of the administration of LA. He was reviewed on the same day by the paediatric neurologist. No further investigations were required. He was discharged well the next day. Conclusion Transient facial nerve palsy and uvula deviation, while rare, can occur after a dental procedure. For paediatric patients, the neurologist’s input helps with parental assurance.
