A male patient needed surgery for the ablation of 4 impacted maxillary molars that prevented chewing and had contributed to progressively worsening trigeminal neuralgia. Two previous anesthetic procedures led to episodes of severe anaphylactic shock with the need for a prolonged stay in the ICU. Hypnotic anesthesia was therefore selected as a safer option for this patient. After 4 preparative sessions, on the day of surgery, the hypnotist provided an induction followed by suggestions for mouth and face anesthesia. Intubation occurred following the introduction of remifentanil and sevoflurane. The surgery lasted about 90 minutes and proceeded uneventfully. This case report describes how conventional and hypnotic anesthesia may work synergistically and may be particularly advantageous in case of drug allergy.
