[Techniques of local anesthesia in the area of the head].

In the head and neck region, many procedures can be performed under local anesthesia. The anesthetic agent can be applied onto the surface of the skin or mucosa (surface anesthesia), it can be infiltrated into the tissue to be treated, or it can be used to block the regional sensory nerve (conduction anesthesia). In this paper, the most important techniques for local anesthesia of the face are presented as a short clinical guide.
