Chemodenervation of muscle(s) refers to the medical procedure in which neurotoxins are injected into specific muscles to induce temporary paralysis or relaxation. This technique is commonly utilized for treating conditions such as spasmodic torticollis, a disorder characterized by involuntary muscle contractions in the neck that result in abnormal head positioning, and spasmodic dysphonia, a voice disorder caused by involuntary spasms of the vocal cords. The procedure typically targets the neck muscles, including the cervicus and sternocleidomastoid muscles, which are crucial for neck movement and stability. By administering neurotoxins, healthcare providers aim to alleviate the symptoms associated with these conditions, improving the patient's quality of life and functional capabilities. The injections are performed at bilateral sites, ensuring comprehensive treatment of the affected muscle groups.
