How to treat a difficult-to-anesthetize patient. Twelve alternatives to the traditional inferior alveolar nerve block.
In the case of the difficult-to-anesthetize patient, the inferior alveolar nerve can be particularly challenging In those patients, other approaches may be necessary to achieve profound anesthesia. This article presents techniques that may be used in those efforts. The clinician can change his target slightly, or increase the dosage of anesthetic. Accessory innervation by lingual and mylohyoid nerves sometimes needs to be addressed. Some standard alternative approaches are Gow-Gates and Varizani-Akinosi injections. Intraosseous and intraligamentary injections should be considered. For lower anteriors, infiltration and incisive nerve blocks can be effective. Slight changes in armamentarium, such as increasing the needle gauge, can be helpful. Twelve approaches that can be used instead of or as an adjunct to, the traditional Halstead injection are described.
