The Link Between Neck, Jaw, and Headaches/Dizziness

by Son’s Rehabilitation Medicine & Chiropractic Clinic in Seoul

— The Cervico–Cranial–Mandibular Disorders (CCMD) Concept

Our body may seem to work in separate parts, but in reality, everything is closely connected.
In particular, the upper cervical spine, the temporomandibular joint (TMJ), and the skull (cranium) move and function together like a team.

This integrated unit is often referred to as the occiput–cervical–mandibular complex, and in academic literature, the term CCMD (Cervico–Cranial–Mandibular Disorders) has been used to describe related dysfunctions.

What is CCMD?

  • Cervico (cervical spine): The neck vertebrae, especially the upper cervical region (C0–C2) that connects with the skull.

  • Cranial (cranium): The skull and related neural structures.

  • Mandibular (mandible, jaw): The TMJ, essential for chewing, speaking, and overall jaw movement.

These areas are not only close anatomically but are also connected through muscles and nerves.
This means that an imbalance in one part can influence the others.

What Symptoms May Be Related?

When alignment or function in the cervico–cranial–mandibular complex is disrupted, the following symptoms are commonly reported:

  • Headaches — especially in the back of the head (occipital region)

  • Jaw problems — clicking sounds when opening the mouth, jaw tightness, bite instability

  • Neck and shoulder pain — chronic stiffness or tension

  • Dizziness, tinnitus, eye strain — thought to be related to cervical and cranial nerve interactions

  • Postural imbalance — forward head posture or asymmetry in the shoulders

Why Look at Them Together?

Conventional medicine often separates these issues:

  • Jaw problems → Temporomandibular Disorders (TMD)

  • Neck issues → Cervicogenic headaches, cervicogenic dizziness

  • Shoulder or posture problems → Musculoskeletal disorders

However, in reality these regions act as a continuous functional complex.
For this reason, international academic discussions have introduced the term CCMD to highlight a more integrated view.

Key Takeaway

  • The neck, jaw, and skull are closely interconnected as a functional unit.

  • Imbalances in one area can contribute to symptoms in another.

  • The academic term CCMD (Cervico–Cranial–Mandibular Disorders) has been proposed to describe this integrated perspective.

Understanding CCMD can help patients see their symptoms in a broader context and encourage more comprehensive self-care.

 What is Central Sensitization? by Son PMR(Physical medicine & Rehabilitation ) & Chiropractic Clinic in Seoul Central sensitization refers to a condition where the brain and spinal cord become abnormally sensitive to pain signals following an injury or inflammation. In simpler terms, the pathways that perceive pain become overly reactive, causing individuals to experience excessive pain from minor stimuli or persistent pain even after healing . Key Features of Central Sensitization Amplified pain responses (Allodynia) Pain is felt even with non-painful stimuli, such as light touch or gentle movement. Increased pain sensitivity (Hyperalgesia) Painful stimuli feel much more intense than usual. Persistent pain Pain can continue even after the original injury or inflammation has resolved. How Central Sensitization Develops Peripheral nerve injury or inflammation → Continuous transmission of pain signals to the spinal cord and brain → Hyperexcitab...
