Frontalis Muscle Contusion

A frontalis muscle contusion is a bruise to the muscle on your forehead. This injury is often the result of a blow or direct impact to the front of the head. In this article, we explain everything—from what the frontalis muscle is to how injuries occur and how to treat, prevent, and diagnose them.

A contusion is the medical term for a bruise. When it occurs in the frontalis muscle—the muscle that covers your forehead—it means that the impact has caused small blood vessels to break and muscle fibers to become damaged. This injury may lead to pain, swelling, and discoloration in the affected area.

Anatomy of the Frontalis Muscle

Understanding the frontalis muscle helps explain how a contusion can affect your appearance and function.

1. Location and Structure

• Location: The frontalis muscle is found in the forehead. It is part of a larger muscle group called the occipitofrontalis (or epicranius).
• Structure: It is a flat, broad muscle that extends from the hair-bearing scalp down to the skin of the eyebrows and forehead.

2. Origin and Insertion

• Origin: The muscle originates at the galea aponeurotica—a tough, fibrous layer covering the top of the skull.
• Insertion: It inserts into the skin above the eyebrows and sometimes blends with the fibers of the eyebrows.

3. Blood Supply

• The frontalis muscle is nourished by blood vessels that include:
  • Supraorbital artery
  • Supratrochlear artery
  • Additional contributions come from branches of the superficial temporal artery

4. Nerve Supply

• The muscle receives signals from the facial nerve (cranial nerve VII), specifically through its temporal branch, which controls muscle movement on the forehead.

Key Functions

1. Raising the Eyebrows: Helps express surprise or curiosity.
2. Wrinkling the Forehead: Commonly used in facial expressions.
3. Enhancing Facial Expression: Contributes to non-verbal communication.
4. Assisting in Scalp Movement: Plays a role in moving the scalp and skin.
5. Protecting the Eyes: By lifting the brows, it can help reduce glare.
6. Maintaining Facial Symmetry: Works with other facial muscles to create balanced expressions.

Types of Frontalis Muscle Contusion

Although contusions are generally classified by severity, here are a few common types related to the frontalis muscle:

1. Superficial Contusion: A mild bruise where the injury affects only the surface fibers of the muscle.
2. Deep Contusion: A more severe injury that affects deeper muscle fibers and may cause more pain and swelling.
3. Compound Contusion: When a bruise is combined with a cut or laceration on the skin.
4. Hematoma-Forming Contusion: A severe type where a collection of blood (hematoma) forms within the muscle tissue.
