Hyoglossus Muscle Spasm

Hyoglossus muscle spasms are involuntary, often painful contractions of the hyoglossus—a thin, quadrilateral extrinsic muscle of the tongue. These spasms can interfere with speech, swallowing, and overall oral comfort. In this comprehensive, SEO‑optimized guide, you’ll find plain‑English explanations of the hyoglossus muscle’s anatomy, the types of spasms you may experience, and evidence‑based information on causes, symptoms, diagnostic tests, treatments (both non‑pharmacological and pharmacological), surgeries, prevention strategies, and when to seek medical care.

A hyoglossus muscle spasm is an involuntary contraction or twitch of the hyoglossus muscle, one of the four extrinsic muscles of the tongue. It can range from a mild twitch to a sustained, painful contraction that makes speaking or swallowing difficult.

Anatomy of the Hyoglossus Muscle

Structure & Location

The hyoglossus is a thin, quadrangular muscle in the floor of the mouth, lying immediately lateral to the geniohyoid. It spans vertically from the hyoid bone up to the side of the tongue KenhubWikipedia.

Origin

It arises from the body and greater horn of the hyoid bone. Fibers from the body overlap those from the greater cornu Wikipedia.

Insertion

The muscle fibers run almost vertically to insert into the inferior and lateral aspects of the tongue, between the styloglossus and the inferior longitudinal intrinsic muscle Wikipedia.

Blood Supply

Vascular supply comes primarily from the sublingual branch of the lingual artery, with additional contributions from the submental branch of the facial artery Radiopaedia.

Nerve Supply

Motor innervation is provided by the hypoglossal nerve (cranial nerve XII), which controls tongue movement Kenhub.

Functions

The hyoglossus muscle has six key roles:

1. Depresses the tongue: Lowers the tongue when speaking or swallowing.

2. Retracts the tongue: Pulls it backward.

3. Flattens the dorsum: Makes the upper surface more convex for speech articulation.

4. Stabilizes the tongue: Helps maintain tongue position during mastication.

5. Assists swallowing: Works with other tongue muscles to move food.

6. Supports oral posturing: Helps keep the airway open during breathing. KenhubWikipedia.

Types of Hyoglossus Muscle Spasms

Hyoglossus spasms are categorized similarly to dystonia and other focal muscle disorders:

• Focal Spasm: Limited to the hyoglossus, causing isolated tongue twitching.

• Segmental Spasm: Involves adjacent tongue muscles (e.g., hyoglossus plus genioglossus).

• Task‑Specific Spasm: Triggered by particular actions, like prolonged speaking.

• Primary (Essential) Spasm: No clear underlying cause; often intermittent Mayo Clinic.

• Secondary Spasm: Linked to neurological or systemic disease (e.g., stroke, Parkinson’s).
