Manual Therapy and Exercises Reduce Tinnitus Severity

Six Clinical Trials Show Jaw and Neck Exercises Combined with Manual Therapy Reduced Tinnitus Severity

A systematic review published in the journal Disability and Rehabilitation analyzed 4,356 research articles to find six studies meeting its strict criteria. Lead researchers from the Federal University of São Carlos in Brazil and the University of Alberta in Canada concluded that a combination of manual therapy and exercises targeted at the neck and jaw reduced tinnitus severity and improved tinnitus-related quality of life. These benefits were observed immediately after treatment and persisted at three- and six-month follow-up assessments.

Temporomandibular Disorders: A Hidden Link to Ear Symptoms

The temporomandibular joints (TMJ) connect your jawbone to your skull. Disorders affecting these joints, muscles, and nerves are collectively called temporomandibular disorders (TMD). Symptoms extend beyond jaw pain and clicking, often including headaches, facial pain, and a cluster of otological—or ear-related—complaints. These include tinnitus, earache, a sensation of ear fullness, vertigo, dizziness, and hearing sensitivity issues like hyperacusis.

A 2019 international web-based survey led by Sarah Michiels of the University of Antwerp found physical symptoms are common in people with tinnitus. Many respondents reported jaw problems, neck pain, and headaches, highlighting the frequent co-occurrence of TMD and tinnitus.

The Anatomical and Functional Connection Between Jaw and Ear

The proximity of the TMJ to the middle ear and the shared neural and muscular networks explain the link. Key structures include:

• The temporomandibular joint: Situated just anterior to the ear canal.
• Muscles of mastication: The masseter, temporalis, and pterygoid muscles control jaw movement. Tension or dysfunction here can affect surrounding tissues.
• The trigeminal nerve: This major cranial nerve provides sensation to the face, jaw, and parts of the ear. It can mediate referred pain and sensory disturbances.
• Neck muscles: The sternocleidomastoid and trapezius muscles influence head posture and jaw alignment.

Dysfunction in this complex region can increase tension, alter blood flow, or affect the delicate Eustachian tube, potentially contributing to the perception of tinnitus and other ear symptoms.

What the Systematic Review Evidence Shows

The 2024 review by Tavares and colleagues provides the most current synthesis of clinical trial data on treating TMD-related ear symptoms.

Combined Therapy Outperforms Exercise Alone for Tinnitus

The central finding is that multimodal treatment works better than isolated approaches. Studies in the review compared “manual therapy combined with exercises” to “exercises alone.” Manual therapy includes techniques like joint mobilizations, soft tissue massage, and stretching performed by a physical therapist or other clinician.

When this hands-on therapy was added to a regimen of structured neck and jaw exercises, patients experienced greater reductions in tinnitus severity. Their quality of life, often measured by tools like the Tinnitus Handicap Inventory, also improved more significantly. The effects were not short-lived; follow-up data showed sustained improvement for at least six months.

Other Otological Symptoms Also Improved with Targeted Therapy

The review found evidence for benefits beyond tinnitus. Earache and the feeling of ear fullness—a common and distressing complaint—improved after interventions like orofacial myofunctional therapy and oral motor exercises compared to receiving no treatment. These therapies focus on coordinating and strengthening the muscles of the face, mouth, and throat.

A Very Low Certainty of Evidence Calls for Better Research

The authors applied the GRADE system, a standard method for rating evidence quality. They assigned an overall rating of “very low” certainty to these findings. This rating stems from limitations in the included studies, such as small sample sizes, potential biases in study design, and variability in how outcomes were measured. It means the results are promising but not conclusive. More high-quality, large-scale randomized trials are needed to confirm the effects and establish optimal treatment protocols.

Practical Applications: What Exercises and Therapies Are Used?

Based on the reviewed studies, effective interventions typically involve a structured, supervised program.

Jaw and Neck Exercises

Exercise therapy aims to restore normal range of motion, coordination, and strength while reducing harmful muscle tension. Common exercises include:

• Gentle jaw opening and closing: Controlled movements within a pain-free range to improve joint mobility.
• Resisted jaw exercises: Using light finger pressure to provide resistance against jaw movement to strengthen muscles.
• Chin tucks and neck retractions: Postural exercises to align the head and neck, reducing strain on the jaw.
• Neck stretching: Techniques to lengthen tight muscles like the sternocleidomastoid and upper trapezius.

Manual Therapy Techniques

These are clinician-administered techniques often combined with exercises:

• Joint mobilizations: Gentle, passive movements of the TMJ to improve its glide and function.
• Soft tissue release: Massage and pressure techniques on the masseter, temporalis, and suboccipital muscles to release tension.
• Myofascial release: Broader techniques addressing the connective tissue network around the jaw and neck.

Orofacial Myofunctional Therapy

This specialized therapy, often provided by speech-language pathologists or dentists, targets the muscles of the lips, tongue, face, and throat. It includes exercises for proper tongue posture, swallowing patterns, and lip seal, which can influence jaw stability and tension.

Actionable Takeaways for Patients and Clinicians

While self-management has limits, understanding the evidence can guide informed decisions.

Seek a Multidisciplinary Assessment

If you experience tinnitus alongside jaw pain, clicking, headaches, or neck pain, consult professionals who understand this connection. A team may include a dentist specializing in TMD, a physical therapist, an otolaryngologist (ENT doctor), and an audiologist. A comprehensive assessment is the first step to determining if your tinnitus has a musculoskeletal component.

Diagnosis of conditions like hyperacusis or misophonia may also involve specialized auditory testing. For insights into how the brain processes sound in these disorders, research comparing misophonia and hyperacusis brain responses is ongoing.

Prioritize Combined, Supervised Treatment

The evidence suggests the most benefit comes from a program that combines active exercises with passive manual therapy, rather than trying one approach alone. Look for a physical therapist or clinician experienced in treating TMD who can provide this integrated care. The supervision ensures exercises are performed correctly and safely.

Focus on Consistency and Long-Term Management

The studies showing benefit at six-month follow-ups indicate that these are not quick fixes but require consistent practice. Exercises often become part of a long-term management plan, similar to physiotherapy for chronic back pain.

Understand the Evidence Landscape

Hope for improvement is reasonable, but expectations should be tempered by the current “very low” certainty of evidence. Not all tinnitus is related to TMD, and even for TMD-related tinnitus, response to therapy can vary. Other avenues for tinnitus management, such as transcranial direct current stimulation (tDCS), are also being investigated scientifically.

Key Takeaways

• A 2024 systematic review of six clinical trials found that manual therapy combined with neck and jaw exercises reduced tinnitus severity and improved quality of life more than exercises alone.
• Temporomandibular disorders frequently co-occur with tinnitus, earache, and ear fullness due to shared anatomy and neural pathways.
• Effective interventions are typically multidisciplinary, involving structured exercises for jaw mobility and neck posture alongside clinician-administered manual therapy.
• Benefits from combined therapy were sustained for at least six months in the reviewed studies.
• The overall certainty of this evidence is rated as very low, highlighting the need for more robust research while supporting current clinical practice.
• Patients with tinnitus and concurrent jaw or neck symptoms should seek assessment from TMD specialists, physical therapists, and audiologists.
• Self-management without professional guidance carries risk and is less supported by evidence than supervised, combined treatment programs.
