Is anesthesia required?

A wide-field cervical nerve plexus block is performed with a local anesthetic. This field block is performed using local anesthesia and US guidance. This effectively numbs the anterior neck and capsule of the thyroid where the nerves are present. Because the internal aspect of the thyroid gland has no sensation, the treatment can be performed with little pain.

Optimal therapy includes communication with the patients during the procedure. General anesthesia is less desirable because the patient cannot speak. Under local anesthesia, we are still able to converse with the patient to assess the quality of the voice. Although rarely necessary, interventions to protect the recurrent laryngeal nerve can be initiated should the patient’s voice becomes weak or hoarse.
