Inferior alveolar nerve block
Regional anesthesia technique targeting the mandibular nerve to anesthetize lower teeth and lip.
Full Definition
The inferior alveolar nerve block is a fundamental anesthetic technique in oral surgery that provides profound anesthesia to the mandibular teeth, lower lip, and chin on the injected side. The injection is administered at the mandibular foramen, requiring precise anatomical knowledge and technique. Complications can include intravascular injection, trismus, or temporary facial nerve paralysis if the injection is misdirected.
