The superior semicircular canal dehiscence syndrome (SSCDS) is a set of hearing and balance symptoms that a rare disease/disorder of the inner ear's superior semicircular canal/duct induces. [ 3 ] [ 4 ] [ 5 ] The symptoms are caused by a thinning or complete absence of the part of the temporal bone overlying the superior semicircular canal of ...
Another type of labyrinthine fistula is the superior semicircular canal dehiscence, which allows the inner ear to be influenced by the intracranial pressure directly. Signs and symptoms [ edit ]
Tullio phenomenon, sound-induced vertigo, dizziness, nausea or eye movement was first described in 1929 by the Italian biologist Prof. Pietro Tullio.(1881–1941) [1] [2] During his experiments on pigeons, Tullio discovered that by drilling tiny holes in the semicircular canals of his subjects, he could subsequently cause them balance problems when exposed to sound.
An expert on the inner ear, Minor is known for identifying the superior canal dehiscence syndrome, a disorder where a hole in the skull bone upsets the inner ear balance canal. [3] For refining a treatment for Ménière's disease using gentamicin, Minor received the Prosper Ménière Society's gold medal in 2010. [4]
The most common inner ear cause of pulsatile tinnitus is superior semicircular canal dehiscence. [58] Pulsatile tinnitus may also indicate idiopathic intracranial hypertension. [59] Pulsatile tinnitus can be a symptom of intracranial vascular abnormalities and should be evaluated for irregular noises of blood flow . [60]
In this approach, the semicircular canals and vestibule, including the utricle and the saccule of the inner ear are removed, causing complete hearing loss in the operated ear. The procedure is typically performed by a team of surgeons, including a neurotologist (an ear, nose, and throat surgeon specializing in skull base surgery) as well as a ...
The lateral semicircular canal (also known as horizontal or external semicircular canal) is the shortest of the three canals. Movement of fluid within its duct corresponds to rotation of the head around a vertical axis (i.e. the neck), or in other words, rotation in the transverse plane. This occurs, for example, when one turns the head from ...
The eyes of the patient can then easily be observed for which kind (horizontal, vertical, or diagonal) of nystagmus is present, to determine which semicircular canal (horizontal, superior, or posterior) is affected. The Dix–Hallpike test is a common test performed by examiners to determine whether the posterior semicircular canal is involved ...
