Tinnitus, or a ringing in the ears, is a common condition that varies from a low roar to a high-pitched sound. It may be subjective (audible only to the patient) or objective (audible to both the patient and others). While there is no approved pharmacotherapy for tinnitus, muscle relaxants have been suggested as a possible treatment. Cyclobenzaprine, a tricyclic antidepressant analog and muscle relaxant, has been found to reduce tinnitus in clinical reports and pilot studies. It is believed that cyclobenzaprine may reduce tinnitus induced by hearing loss via mechanisms similar to those of drugs that reduce phantom pain. In addition to muscle relaxants, other treatments for tinnitus include biofeedback training, nerve blocks/injections, and physical therapy targeting posture correction and muscle relaxation.

Cyclobenzaprine, a muscle relaxant, is effective in reducing tinnitus
Tinnitus, the perception of sounds that do not have an external source, is a highly prevalent disorder. While a wide range of drugs have been investigated for the treatment of tinnitus, no approved pharmacotherapy exists. However, muscle relaxants are among the medications that have been prescribed off-label to treat tinnitus.
Cyclobenzaprine is a muscle relaxant that has been investigated in several studies for its potential to reduce tinnitus. In one open-label pilot study, high doses of cyclobenzaprine (30 mg) resulted in a significant reduction in tinnitus severity, as measured by the Tinnitus Handicap Inventory (THI) score, over a 12-week period. This study included a maximum of 20 patients per group and compared the effects of cyclobenzaprine to other treatments such as orphenadrine, tizanidine, and eperisone. The results showed that high-dose cyclobenzaprine was more effective in reducing tinnitus severity compared to the other treatments.
Another open-label study by Coelho et al. in 2012 also investigated the effects of cyclobenzaprine on tinnitus. This study found that cyclobenzaprine, a commonly prescribed centrally acting muscle relaxant, helped in reducing tinnitus severity. Additionally, Lobarinas et al. conducted a study on rats with noise-induced tinnitus and found that treatment with cyclobenzaprine resulted in partial to complete suppression of unilateral tinnitus.
The use of cyclobenzaprine in the treatment of tinnitus has been explored in various studies, and the findings suggest that it may be effective in reducing tinnitus severity, particularly at higher doses. However, it is important to note that while cyclobenzaprine has shown potential, there is still a lack of approved pharmacological treatments specifically for tinnitus.

Muscle tightness in the neck can cause tinnitus
Tinnitus is the perception of sound when there is no external source. It can be a constant buzzing or ringing in the ears, or it can be intermittent. While non-pulsatile tinnitus is fairly common, pulsatile tinnitus is rare. Pulsatile tinnitus is a rhythmic buzzing or whooshing sound in the ears that resembles a pulse. It is usually described as a whooshing, throbbing, or thumping sound, and is generally synchronized to your heartbeat.
Tight neck muscles may cause pulsatile tinnitus in some cases, but it is not the most common cause of the condition. The most common causes are vascular, relating to problems with the blood vessels, such as unmanaged high blood pressure. However, muscular and skeletal problems such as an uneven bite, temporomandibular (TMJ) disorder, and muscle tension are also potential causes.
There are several treatments that can help alleviate tinnitus symptoms caused by muscle tightness in the neck. Relaxing tense muscles may help ease tinnitus in some cases. Muscle relaxation techniques such as gentle stretching, massage, yoga, and physical therapy can be beneficial. Transcutaneous electrical nerve stimulation (TENS) is another treatment option that involves using a device to deliver small electrical pulses through electrodes placed on the skin around or behind the ears and neck. These electrical pulses may influence the nerves connected to the auditory system, allowing the brain to respond differently and potentially leading to the suppression of symptoms.
In addition to these treatments, addressing cervical spine instability can also help alleviate tinnitus symptoms. Cervical spine instability can lead to compression of the vagus nerve, which controls the levator veli palatini muscle, and the trigeminal nerve, which controls the tensor veli palatini muscle, resulting in dysfunction of these muscles. Repairing cervical spine neck ligaments and restoring stability to the cervical spine can help improve muscle function and alleviate Eustachian Tube Dysfunction, thereby reducing tinnitus symptoms.

Cervicogenic tinnitus is caused by problems in the cervical spine region
Tinnitus is a prevalent disorder characterised by the phantom perception of sounds. While the causes of tinnitus are varied, one speculated cause is problems in the cervical spine region. This is known as cervicogenic tinnitus.
Cervicogenic tinnitus is not a generally accepted pathogenetic subtype. However, it has been observed that tinnitus may prevail in various clinical situations with muscle tension in the head-neck region, influenced by psychological factors. Cervical spine disorders (CSD) are among the most common complaints encountered by physicians. The pathogenesis of tinnitus induced by CSD remains unclear, but it is believed that CSD could trigger a disinhibition of dorsal cochlear nucleus (DCN) activity in the auditory pathway. CSD can also cause inner ear blood impairment induced by vertebral arteries hemodynamic alterations and trigeminal irritation. Connections between the dorsal column of the spinal cord and the cochlear nuclei (CN) have been found in several animal studies.
In humans, the importance of the craniovertebral and cervicomedullar angles in the causation of cervicogenic headaches is well described. A case study of a patient with chronic tinnitus reported that the condition completely disappeared within 4 weeks with the use of a cervical collar (CC). Another case study reported that a patient with tinnitus demonstrated a complete reversal of symptoms after 2.5 months of treatment focused on normalising cervical spine mobility through repetitive movements, joint mobilisation, and soft tissue massage.
While the evidence for effective diagnosis and treatment of cervicogenic somatic tinnitus is limited, the high prevalence of tinnitus and cervical syndromes suggests a potentially broad relevance for further research in this area.

Biofeedback training can reduce the intensity of tinnitus
Tinnitus, the perception of sounds that don't exist externally, is a prevalent disorder that can have debilitating psychological consequences. While there is no cure, several interventions have been found to help individuals better cope with the condition. Biofeedback training is one such intervention that has been studied for its potential to reduce the intensity of tinnitus.
Biofeedback is a technique that involves providing individuals with information about their brain activity to help them develop strategies to control and reduce the activity of certain brain regions. In the context of tinnitus, biofeedback training aims to target the primary auditory cortex, which is involved in sound perception. By using neuroimaging techniques, such as functional MRI, researchers can create a map of the brain and identify areas with high activity during sound stimulation. This information can then be used to develop targeted biofeedback training protocols.
An intensive study involving seven subjects with chronic tinnitus tested the hypothesis that biofeedback and relaxation training could positively affect their condition. The participants underwent a 5-month program consisting of weekly 90-minute sessions with a biofeedback specialist. While audiometric evaluations showed no changes in tinnitus loudness, the training provided psychological benefits, with three participants reporting substantial improvements in coping with tinnitus, two describing moderate improvements, and two experiencing modest gains.
Another study by Matthew Sherwood of Wright State University involved healthy college students who were subjected to artificial white noise to simulate tinnitus. The participants underwent fMRI-neurofeedback training sessions, during which they were exposed to alternating periods of sound and silence. The results showed that most participants could use biofeedback to reduce the impact of the noise on their task performance, indicating a potential benefit for individuals with tinnitus.
Neurofeedback, a type of biofeedback, has also been explored as a treatment for tinnitus. One study protocol aims to investigate the effectiveness of an alpha/delta neurofeedback training protocol compared to beta/theta neurofeedback or a diary control group. The training sessions are designed to decrease ADR (alpha activity enhancement and/or delta activity reduction) and BTR (theta activity inhibition and/or beta activity reinforcement) bilaterally over the fronto-central cortex. The study will evaluate changes in tinnitus sound perception and psychological distress associated with the condition.
In conclusion, while there is no cure for tinnitus, biofeedback training, including neurofeedback, has shown promise in reducing the intensity of the condition and improving individuals' ability to cope with its psychological impacts. Further research with larger sample sizes and controlled conditions is needed to confirm the effectiveness of specific biofeedback training protocols in treating tinnitus.

Tinnitus may be caused by muscle spasms in the middle ear
Tinnitus is a condition where one perceives sounds like ringing or buzzing that are not from an external source. It may be subjective (audible only to the patient) or objective (audible to others as well). Objective tinnitus is rare and affects only 1% of people with tinnitus.
Muscular tinnitus is a very rare type of tinnitus where one hears sounds caused by muscle spasms in the middle ear. It is associated with involuntary spasms or twitching of the tiny stapedius and tensor tympani muscles in the middle ear, which is the area between the eardrum and inner ear. These muscles control the movement of the bones that carry sound from the air to the inner ear. The muscles contract to reduce the volume of loud noises. If they contract rhythmically, one may hear clicking or other repetitious sounds. The sound that muscular tinnitus creates is usually a clicking noise, but it has also been described as throbbing, tapping, crackling, bubbling, ticking, twitching, blowing, drum-like thumping, fluttering, whooshing, or gushing.
Middle ear myoclonus (MEM) is a term used to explain symptoms of tinnitus caused by the dysfunctional movement of either the tensor tympani or stapedius muscles. Several cases of MEM have been described following a facial nerve injury, where pathologic peripheral nerve discharges and/or post-injury synkinesis could explain myoclonic activity. There is no imaging evidence of brainstem pathology to correlate with a source of segmental myoclonus in MEM tinnitus.
If the cause of muscular tinnitus is diagnosed and treated, it may be resolved. Doctors may prescribe muscle relaxant drugs or surgery to cut the spastic muscle if the muscle spasm continues. Cyclobenzaprine, a centrally acting muscle relaxant, has been shown to reduce tinnitus severity in patients.

Frequently asked questions
Tinnitus is the medical term for ringing in the ears. It varies from a low roar to a high-pitched type of sound. It may be intermittent or constant, mild or severe.
There are many possible causes of tinnitus, including tightness or spasms in the neck muscles, which can interfere with normal auditory function. Other causes include abnormal growth on blood vessel walls, muscle spasms in the middle ear, or abnormalities in the blood vessels surrounding the ear.
Muscle relaxants can help with tinnitus caused by problems originating in the cervical spine region, called cervicogenic tinnitus. Clinical studies show that treatments addressing neck muscle dysfunction, such as physical therapy targeting posture correction and muscle relaxation, can significantly reduce tinnitus intensity for some patients. Cyclobenzaprine, a tricyclic antidepressant analog, has also been suggested as an effective treatment for tinnitus.
Other treatments for tinnitus include biofeedback training, nerve blocks/injections, and the use of a tinnitus masker, a small electronic instrument built into a postauricular (over the ear) hearing aid case that generates noise to prevent the wearer from hearing their own head noise.
