Pulsatile tinnitus is a rhythmical noise that usually has the same beat as the heart, and it is rarely described as a ringing sound. It is often associated with muscle tension, especially in the jaw and neck, which can be caused by several degenerative diseases affecting the head and neck, such as amyotrophic lateral sclerosis or multiple sclerosis. Muscle tension in these areas can be relieved through various treatments, including focal administration of lidocaine, bite splints, home exercises, and chiropractic care, which may help alleviate tinnitus.

What You'll Learn
Muscle tension in the jaw and neck can cause tinnitus
Tinnitus is the perception of noises in the head and/or ear. It can present as a steady ringing, buzzing, hissing, whistling, or other noises. The volume and duration of the noises can vary from one episode to the next.
Pulsatile tinnitus is a rhythmic noise that usually has the same beat as the heart. It is rarely described as a ringing sound, but more often as a whooshing, pulsing, or screeching sound. It is caused by a change in blood flow in the vessels near the ear or a change in awareness of that blood flow. These vessels are located in the large arteries and veins in the neck and base of the skull, or the smaller ones in the ear itself.
Somatic testing has shown that pulsatile tinnitus can be abolished or transformed to nonpulsatile tinnitus by activation of the somatosensory system of the upper neck or jaw through intense muscle contractions or pressure on muscles and tendons. This suggests that the somatosensory system is causing or interacting with the auditory system to produce tinnitus.
Overall, muscle tension in the jaw and neck can cause tinnitus, and treatment of this muscular tension through various methods can help reduce or abolish tinnitus symptoms.

Temporomandibular disorder and muscular tension can cause tinnitus
Tinnitus is the perception of noises in the head and/or ear. It can be described as a steady ringing, buzzing, hissing, whistling, or other noises. The volume and duration of the noises can vary from one episode to the next.
Pulsatile tinnitus is a rhythmic noise that usually has the same beat as the heart. It is rarely described as a ringing sound, but more often as a whooshing, pulsing, or screeching sound. It is caused by a change in blood flow in the vessels near the ear or a change in awareness of that blood flow. These vessels are located in the large arteries and veins in the neck and base of the skull, or the smaller ones in the ear itself.
Muscular tension can cause tinnitus. Somatosensory pulsatile tinnitus syndrome is a subtype of tinnitus that can be abolished or transformed to nonpulsatile tinnitus by activation of the somatosensory system of the upper neck or jaw, such as through intense muscle contractions or pressure on muscles and tendons. Intense muscle contractions can suppress the pulsations of tinnitus.
Temporomandibular disorder (TMD) is a condition that often presents with muscular tension in both the jaw and neck, as well as tinnitus, vertigo/dizziness, and aural fullness. Treatment for TMD-related tinnitus typically involves reducing muscular tension. This can be achieved through regular stretching exercises of the suboccipital muscles, rotation movements in the atlanto-occipital joint, and relaxing exercises involving breathing with the diaphragm. Focal administration of lidocaine into jaw muscles or neck muscles may also temporarily reduce tension and, consequently, tinnitus.
In addition to muscle tension reduction techniques, patients with TMD and tinnitus have shown improvement through the use of bite splints, cognitive therapy, and home exercises. Chiropractic care is another successful management option for reversible functional disorders of the cervical spine and other body structures.

Somatosensory activation can cause pulsatile tinnitus
In some cases of pulsatile tinnitus, the activation of the somatosensory system through somatic testing can induce or suppress the tinnitus. Somatic testing involves strong contractions or compressions of the neck and jaw muscles. For example, carotid compression affected pulsatile tinnitus in four out of fourteen cases, with all tinnitus being suppressed in two of the cases. This suggests that the suppression of tinnitus may be due to diminished carotid blood flow, rather than interactions between the somatosensory and auditory systems within the central nervous system.
The underlying cause of somatosensory pulsatile tinnitus may be related to cardiac synchronous somatosensory activation of the central auditory pathway or a failure of the somatosensory-auditory central nervous system to suppress cardiac somatosounds. Other possible causes include a high cardiac output state, such as anaemia or hyperthyroidism, bilateral carotid stenosis, or a carotid-cavernous fistula.
The treatment of somatosensory pulsatile tinnitus aims to reduce muscular tension in the jaw and neck. This can be achieved through focal administration of lidocaine into the jaw or neck muscles to temporarily reduce tension and relieve tinnitus. Regular stretching exercises of the suboccipital muscles and rotation movements in the atlanto-occipital joint, especially on the restricted side, can also help reduce tension-related symptoms. Additionally, chiropractic care and atlas therapy have been found to alleviate symptoms and improve structural and functional issues.

Pulsatile tinnitus can be caused by muscle spasms in the ear
Pulsatile tinnitus is a rhythmical noise that usually has the same beat as the heart. It is a type of objective tinnitus, which is defined as a sound that arises from an "objective" source and can be heard by an outside observer under favourable conditions. Objective tinnitus is usually caused by disorders affecting the blood vessels (vascular system) or muscles (muscular system).
In addition to the middle ear, muscle spasms in the soft palate at the back of the throat can also cause pulsatile tinnitus. This is a rare cause, and people with this form of tinnitus should consult a doctor as there is a small chance that an underlying cause can be detected.
Furthermore, temporomandibular disorder, which is characterised by muscular tension in the jaw and neck, has been associated with tinnitus. Treatment of this disorder and relief of muscular tension may also relieve tinnitus. This can be achieved through various methods such as bite splints, cognitive therapy, home exercises, and chiropractic care.
While muscle tension and spasms can contribute to pulsatile tinnitus, it is important to note that this type of tinnitus is primarily caused by vascular problems in the head and neck. These vascular issues lead to changes in blood flow, resulting in the characteristic whooshing, pulsing, or screeching sounds of pulsatile tinnitus.

Muscle relaxants and surgery can treat muscular tinnitus
Pulsatile tinnitus is most commonly caused by vascular problems in the head and neck. However, it can also be caused by muscle spasms in the middle ear, which is the area between the eardrum and inner ear. This is known as muscular tinnitus.
Muscular tinnitus is associated with involuntary spasms or twitching of the stapedius and tensor tympani muscles in the middle ear. These muscles are responsible for dampening loud sounds and protecting the inner ear from excessive noise. When they contract rhythmically, clicking or other repetitive sounds may be heard.
If the cause of muscular tinnitus is diagnosed and treated, it may be resolved. Doctors may prescribe muscle relaxant drugs if the cause of muscular tinnitus cannot be determined or if it persists after treatment. Muscle relaxants such as bromazepam, cyclobenzaprine, and baclofen have been used to treat tinnitus with varying levels of success. While some patients have reported relief from tinnitus symptoms with these medications, others have found them ineffective. It is important to note that muscle relaxants are typically prescribed off-label for tinnitus treatment and may have side effects.
In some cases, surgery may be considered for the treatment of muscular tinnitus. This involves either injecting a local anesthetic or Botox into the twitching ear muscles to calm them down or surgically dividing or cutting these muscles to stop the recurrent muscle spasms (myoclonus). Surgery is typically a last resort if other treatment options have been exhausted.
