Red ear syndrome (RES) is a rare disorder of unknown etiology which was originally described in 1994. The defining symptom of red ear syndrome is redness of one or both external ears, accompanied by a burning sensation. [1] A variety of treatments have been tried with limited success. [1]
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 ...
Eustachian tube dysfunction can be caused by a number of factors. Some common causes include the flu, allergies, a cold, and sinus infections. [6] In patients with chronic ear disease such as cholesteatoma and chronic discharge, studies showed that they have obstructive pathology at the ear side of the Eustachian tube.
Ear infection symptoms usually include a fever, ear pain or fullness, and a headache in children and adults. Antibiotics clear up most ear infections.
Endolymphatic hydrops is a disorder of the inner ear. It consists of an excessive build-up of the endolymph fluid, which fills the hearing and balance structures of the inner ear. Endolymph fluid, which is partly regulated by the endolymph sac, flows through the inner ear and is critical to the function of all sensory cells in the inner ear.
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.
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]

Fever or headaches may also be present. Infants usually show nonspecific symptoms, including anorexia, diarrhea, or irritability. Drainage from the ear ...
