Abstract

Neurological complications following the administration of a local anaesthetic can be alarming. By reading reports of such incidents, dentists who find themselves in similar situations will be able to reassure their patients and act accordingly. The authors have reviewed the literature for those neurological complications that have been reported and offer an explanation of their aetiology. Examples of complications covered are facial nerve palsy, transient amaurosis, post-injection paraesthesia, Horner's syndrome, transient paralysis of combined cranial nerves III, IV and VI, sudden unilateral deafness and abducens nerve palsy. A thorough knowledge of the relevant anatomy pertinent to the various injections used in dental surgery is essential and is highlighted in the text.
