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.
