Anatomy of Tinnitus
Ear Structure: A Detailed Look into the Anatomy of the Ear
The human ear is an architectural masterpiece, finely tuned to perceive an array of sounds. Divided into three main parts, the outer ear, the middle ear, and the inner ear, each plays a critical role in sound transmission.
The Outer Ear: Comprising the pinna and auditory canal, it funnels sound waves into the ear. In some cases of tinnitus, blockages or abnormalities may create perceived noises.
The Middle Ear: Hosting the tympanic membrane (ear drum) and three tiny bones (ossicles), this area amplifies sound vibrations. Dysfunction in these structures can lead to tinnitus.
The Inner Ear: This contains the cochlea and auditory nerves, where sound waves are converted into electrical signals sent to the brain. Damage or degeneration within the inner ear is often at the heart of tinnitus.
The Auditory Pathway: Understanding the Path Sound Waves Take
The journey of sound is a captivating process. From the outer ear, sound waves traverse a pathway through the middle ear into the inner ear. Here, the cochlea's hair cells translate these vibrations into neural signals that the auditory nerve transmits to the brain. Disruptions anywhere along this pathway, whether from injury, disease, or exposure to loud noises, may give rise to phantom tinnitus sounds.
Neurological Factors: Examination of How Tinnitus is Related to Neurological Aspects
Tinnitus is not merely an ear condition but a complex neurological phenomenon. The auditory cortex, the brain's sound-processing center, can become hyperactive or miscommunicate with other brain areas, leading to tinnitus. Neurological disorders, neurotransmitter changes, or neural pathway alterations can all contribute to this mysterious condition.
Fascia Involvement: Discussing the Role of Fascia in the Ear
The fascia, a band of connective tissue permeating the body, plays a less understood but potentially significant role in tinnitus. Within the ear, the fascia supports and connects various structures. Abnormal tension or restrictions in the fascial system might affect the ear's mechanics and lead to tinnitus symptoms. Recent interest in fascial manipulation as a therapeutic approach underlines the importance of understanding fascia's intricate role in ear health and tinnitus.
Aetiology of Tinnitus
Tinnitus is a multifaceted symptom characterized by the perception of sound in the absence of an external auditory stimulus. Its etiology can be complex, often involving multiple interrelated factors:
Sensorineural Causes: Consultation with an audiologist or ENT specialist is vital for cases involving cochlear damage or auditory pathway lesions. Their expertise in cochlear implants, hearing aids, or medical management can provide tailored treatment.
Conductive Causes: Middle ear pathologies require the nuanced care of an ENT specialist, who can administer interventions such as tympanoplasty or stapedectomy to address specific conditions like otosclerosis or tympanic membrane perforation.
Central Causes: Neurologists or specialized audiologists may be engaged to assess and manage central auditory processing disorders or cortical reorganization, employing methods like cognitive therapy or sound therapy.
Metabolic Factors: Collaboration with endocrinologists or internal medicine specialists is crucial in addressing underlying metabolic conditions like hypothyroidism or diabetes, aligning overall health management with tinnitus care.
MSK Tinnitus
Tinnitus, a complex auditory phenomenon, is deeply interconnected with musculoskeletal (MSK) structures, particularly the Temporomandibular Joint Disorder (TMJ/TMD) and cervical spine. This section, "MSK Tinnitus," delves into these relationships, exploring the underlying anatomical, neurological, and biomechanical links that connect auditory symptoms to MSK dysfunction. In these specific instances of tinnitus, manual therapy, encompassing methods like Motion Specific Release (MSR), manipulation, and mobilization, offers a great benefit.
By targeting the intricate interactions between auditory function and musculoskeletal structures, manual therapy provides a tailored approach that addresses tinnitus's symptomatology and underlying causes. The following material elaborates on these connections, demonstrating the promise and potential of manual therapeutic intervention in managing MSK-related tinnitus.
Tinnitus and Temporomandibular Joint Disorder (TMJ/TMD)
The connection between tinnitus and TMJ/TMD is one of converging neurological pathways and muscular interactions:
Anatomical Proximity: The proximity of the temporomandibular joint to the middle ear allows for mechanical interactions, potentially influencing auditory function.
Neuromuscular Factors: Shared nerve innervation and reflex pathways create potential neuromuscular links between TMJ/TMD and tinnitus.
Treatment Correlation: Some studies have noted improvement in tinnitus following successful TMJ/TMD therapy, highlighting the intertwined nature of these conditions.
Tinnitus and Cervical Spine Dysfunction
Cervical spine dysfunction presents another intriguing connection with tinnitus:
Somatic Tinnitus: Tinnitus generated or modulated by input from somatic structures, particularly the cervical spine, represents a recognized subtype of the condition.
Cervical Inputs: Dysfunction in the cervical spine may influence auditory processing through complex neurological pathways, involving dorsal cochlear nuclei and trigeminal cervical complex.
Therapeutic Implications: Addressing cervical spine dysfunction can improve somatic tinnitus, aligning with a biomechanical model of care.
Diagnosis and Differential Diagnosis (DDx)
Clinical Examination
Diagnosing tinnitus requires empathy, clinical acumen, and collaboration across medical disciplines.
History: The practitioner listens attentively to the patient's experience, considering onset, duration, and lifestyle impacts.
Physical Examination: A thorough examination of relevant structures is vital, including a full orthopedic, neurological, and vascular examination. This comprehensive assessment helps identify potential physical contributors to tinnitus and guides the personalized treatment plan.
Examination Demonstration Videos
TMD Exam: In this video, we provide an in-depth guide on how to diagnose temporomandibular disorder (TMD). This process requires a meticulous review of the patient's medical history and an extensive physical examination.
Cervical Examination - Orthopaedic Testing: In this video Dr Mylonas performs a cervical orthopedic examination covering: palpation, range of motion, orthopedic examinations.
Cranial Nerve Exam: Performing a cranial nerve examination in the case of tinnitus is essential for identifying underlying issues with the cranial nerves, such as vestibulocochlear nerve disorders, and assessing associated neurological conditions. This examination supports comprehensive treatment planning, including the possibility of manual therapy if the tinnitus is musculoskeletal (MSK) related, and guides future management.
Diagnostic Tests: The Multidisciplinary Approach
The complexity of tinnitus calls for an interdisciplinary approach, bringing together various specialists depending on the scope of practice of the MSK practitioner.
Audiometry: Engaging with audiologists or hearing specialists allows for precise hearing loss assessment, an essential step in understanding tinnitus.
Tympanometry or Other Diagnostic Methods: Collaborating with ENT specialists or other professionals who can order and interpret these tests adds depth to the diagnosis, identifying middle ear problems or other underlying issues.
MRI and CT Scans: This may be required to identify complex structural abnormalities.
Differential Diagnosis
Tinnitus is not a one-size-fits-all condition. Differential diagnosis involves considering other conditions that may mimic tinnitus.
Meniere's Disease: A disorder of the inner ear causing symptoms such as vertigo, hearing loss, and tinnitus, requiring comprehensive assessment with otolaryngologists for accurate differentiation.
Acoustic Neuroma: A benign tumor on the auditory nerve that can cause hearing loss, balance issues, and tinnitus, warranting collaboration with neurologists for precise diagnosis and management.
Medication Side Effects: Certain medications, such as aspirin at high doses, can lead to or exacerbate tinnitus symptoms. Working with pharmacists provides guidance on identifying and managing these medication-related considerations.
MSR Treatment for MSK Tinnitus
Motion Specific Release (MSR) is an innovative manual treatment system that offers a multifaceted approach to tinnitus, addressing both the Temporomandibular Joint Disorder (TMJ/TMD) and cervical dysfunction. With its blend of soft tissue procedures, osseous mobilization/manipulation, acupuncture/acupressure, and functional exercise programs, MSR provides a targeted, patient-centric intervention for tinnitus patients. The following sections will delve into the specifics of MSR treatment protocols.
10-Point TMJ/TMD Protocol
Dr. Brian Abelson, the developer of MSR, has created a 10-point TMJ/TMD protocol designed to address key areas contributing to tinnitus. For example, the protocols addresses:
Masseter Muscle Trigger Points: These deep points refer pain to the TMJ and ear and may cause tinnitus symptoms. Specialized techniques that focus on these areas can alter tinnitus symptoms and enhance overall patient comfort.
Lateral Pterygoid Muscle Trigger Points: Targeting these points, potentially linked to tinnitus, can mitigate symptoms such as sinus pain and TMJ discomfort.
Video Demonstration
The following video demonstrates one of the procedures used in the 10-point TMJ/TMD protocol.
Masseter Release: Addressing trigger points in the masseter muscle's deeper sections can alleviate pain and discomfort, and prevent them from affecting the Temporomandibular Joint (TMJ) and ear, potentially leading to tinnitus. In the accompanying video, Dr. Abelson demonstrates the Motion Specific Release (MSR) technique for masseter muscle release.
Addressing Cervical Dysfunction with MSR
Cervical dysfunction presents unique challenges in tinnitus management. MSR protocols provide a comprehensive treatment strategy, employing soft tissue procedures and osseous manipulation to address cervical issues. Recognizing that lateral pterygoid muscle trigger points may not resolve until cervical problems are addressed.
Video Demonstration

Treatment Frequency Recommendations for Tinnitus
The proposed treatment regimen is designed to traverse the varying response trajectories to manual therapy for tinnitus, ensuring a tailored approach that evolves with the patient's progress and comfort level. Sustained dialogue between the patient and healthcare provider is pivotal in fine-tuning the treatment frequency and strategy for enhanced tinnitus management.
Below, a potential treatment plan is presented based on either a positive response to treatment or the persistence of symptoms. For achieving optimum outcomes, patient adherence to both treatment sessions and home exercise is crucial.
Initial Treatment Phase:
MSR Manual Therapy: 2 sessions per week for two weeks to address TMJ/TMD and cervical dysfunction.
Home Exercises: Daily functional exercise programs as prescribed by the MSR practitioner.
Response Assessment:
Evaluate the patient's response to therapy during follow-up appointments, typically after two weeks of treatment.
Positive Response:
MSR Manual Therapy: Reduce to 1 session per week as symptoms alleviate.
Home Exercises: Continue daily routines; adjust as necessary based on professional advice.
Persistent Symptoms:
MSR Manual Therapy: Maintain or increase frequency to 2-3 weekly sessions, reassessing the treatment approach weekly.
Home Exercises: Re-evaluate and modify exercises under professional guidance, ensuring correct technique and adherence.
When performing manual therapy for Tinnitus, treatment should continue as long as there's an improvement in symptoms and function. If progress is noted and functional goals aren't yet met, ongoing therapy can be beneficial. If there are no noticeable results, only marginal improvements, or if progress plateaus, then treatment should be reconsidered or halted.
You should transition to maintenance care once the patient has achieved consistent symptom relief and optimal functional levels, ensuring that the achieved progress is sustained and potential recurrences are minimized. All decisions should be based on regular assessments and patient feedback.
Maintenance Phase:
MSR Manual Therapy: Monthly sessions or as needed for symptom management.
Home Exercises: Daily routines to maintain benefits and prevent symptom recurrence, with periodic reviews by healthcare professionals.
When considering treatment for tinnitus using MSR protocols, the primary focus is on achieving optimal results. The treatment plan is tailored, starting with four sessions in the initial phase. Based on the patient's response, sessions may be adjusted. The number of required visits is based on achieving the best possible outcome for the patient.
Exercise Protocols for TMD and Cervical Dysfunction
In addition to manual therapy, MSR includes specific exercise protocols for both TMD and cervical dysfunction. These exercises, designed to reinforce the manual therapy, extend the benefit of MSR treatment and promote long-term recovery. Below are just a few of examples that we could possibly recommend depending on the specific case.
Video Demonstrations
The following videos demonstrates some of the exercise recommendation that we provide for our patient with TMD or Cervical related Tinnitus.
