AZENHA, Marcelo Rodrigues; SICCHIERI, Luciana; OLIVEIRA NETO, Patrício José de  and  ROSA, Adalberto Luiz. Facial nerve palsy after mandibular anesthesia technique. Rev. cir. traumatol. buco-maxilo-fac. [online]. 2010, vol.10, n.2, pp. 9-11. ISSN 1808-5210.

Facial nerve palsy has many etiologies, such as viruses, facial trauma, iatrogenesis, tumors, idiopathic conditions, cerebral infarction and pseudobulbar palsy, as a result of which it is rarely observed during dental treatment. In this situation, it may be associated with the injection of a local anesthetic, prolonged surgical procedure for the removal of mandibular molars and infections of dental origin. We report a case of complete facial nerve palsy during a mandibular nerve block anesthesia in a 63-year-old woman. The full recovery of facial movements was attained after a few hours and she was discharged. The surgical procedure was performed two weeks later.
