According to the literature vascular lesions are reported in 6% of intraoral conduction anesthesia. A possible consequence is the intraarterial injection of catecholamin added local anesthetic. Due to a long lasting angiospasm necrosis of local mucosae and extraoral skin are possible. In a young female patient extraoral necrosis of parts of the skin of the lower lip and intraoral mucosa appeared, following intraoral conduction anesthesia. Subsequently a scar persisted needing a plastic cicatricotomy. Moreover sensitivity in the area of distribution of the mental nerve was deranged.
