Ear wiggling is movement of the external ear using the three muscles which are attached to it forward, above, and behind.Some mammals such as cows have good control of these muscles, which they use to twitch and orient their ears, but humans usually find this difficult.
The tensor tympani is a muscle within the middle ear, located in the bony canal above the bony part of the auditory tube, and connects to the malleus bone. Its role is to dampen loud sounds, such as those produced from chewing, shouting, or thunder.
Symptoms are believed to occur as the result of increased fluid buildup in the labyrinth of the inner ear. [3] Diagnosis is based on the symptoms and a hearing test. [3] Other conditions that may produce similar symptoms include vestibular migraine and transient ischemic attack. [1] No cure is known. [3]
Tonic tensor tympani syndrome is a disease of the tensor tympani muscle, described by Klochoff et al. in 1971. [1] [2] The tensor tympani muscle is one of the two middle ear muscles that support the three middle ear bones, called the ossicles.
Cochlear hydrops preferentially affects the apex of the cochlea where low-frequency sounds are interpreted. Due to the fluid imbalance in this area, parts of the cochlea are stretched or under more tension than usual, which can lead to distortions of sound, changes in pitch perception, or hearing loss, all usually in the low frequencies.
It is called preauricular sinus which, according to the U.S. National Institutes of Health, or NIH, "generally appears as a tiny skin-lined hole or pit, often just in front of the upper ear where ...
Symptoms may include a sense of fullness in the ear, tinnitus, and dizziness. [7] [8] The model details how symptoms may be initiated by tensor tympani muscle damage or overload due to acoustic shock or trauma. Hypercontraction or hyperactivity of the muscle may cause an "ATP energy crisis." The muscle is then forced to create energy without ...
Ménière's disease frequently presents with recurrent, spontaneous attacks of severe vertigo in combination with ringing in the ears , a feeling of pressure or fullness in the ear (aural fullness), severe nausea or vomiting, imbalance, and hearing loss. [9] [25] [38] As the disease worsens, hearing loss will progress.
