Other possible causes of vertigo in divers: Inner ear barotrauma can lead to varying degrees of conductive and sensorineural hearing loss as well as vertigo. It is also common for conditions affecting the inner ear to result in auditory hypersensitivity. [19] Two possible mechanisms are associated with forced Valsalva manoeuvre.
The presence of dehiscence can be detected by a high definition (0.6 mm or less) coronal CT scan of the temporal bone, currently the most reliable way to distinguish between superior canal dehiscence syndrome (SCDS) and other conditions of the inner ear involving similar symptoms such as Ménière's disease, perilymphatic fistula and cochlea ...
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]
[2] [3] [4] Both conditions involve inflammation of the inner ear. [5] Labyrinths that house the vestibular system sense changes in the head's position or the head's motion. [6] Inflammation of these inner ear parts results in a vertigo (sensation of the world spinning) and also possible hearing loss or tinnitus (ringing in the ears). [6]
Cochlear hydrops (or cochlear Meniere's or cochlear endolymphatic hydrops) is a condition of the inner ear involving a pathological increase of fluid affecting the cochlea. This results in swelling that can lead to hearing loss or changes in hearing perception. It is a form of endolymphatic hydrops and related to Ménière's disease. Cochlear ...
Benign paroxysmal positional vertigo (BPPV) is a disorder arising from a problem in the inner ear. [3] Symptoms are repeated, brief periods of vertigo with movement, characterized by a spinning sensation upon changes in the position of the head. [1] This can occur with turning in bed or changing position. [3]
It can also be a sign of an inner ear infection or problems with blood supply to the inner ear. In some cases, vertigo may be a symptom of a stroke . Some additional causes of vertigo include:
This can result in leakage of the perilymph into the middle ear. [1] This includes specifically a perilymph fistula (PLF), an abnormal connection between the fluid of the inner ear and the air-filled middle ear. This is caused by a rupture of the round window or oval window ligaments separating the inner and middle ear. [1]
