Crack on the case of semicircular canal

Semicircular canal with crack, sound or pressure can induce vertigo. Synchronized with the pulse of the patient may have tinnitus, gaze instability during head movements. Weber test bias ear symptoms, but can lead to transfer an element of the stirrup muscle reflex,[link widoczny dla zalogowanych], most of the pressure changes in patients and / or sound stimulation can lead to superior semicircular canal associated with the vertical of a torsion nystagmus, and some also with the superior semicircular canal leads to the relevant deflection nystagmus. VEMP suggest the sound of all the patients were hypersensitive. 1 mm in the coronal of a high-resolution CT at level 1 to 4 semicircular canal can be displayed on the split. Cause of the syndrome involves two processes,[link widoczny dla zalogowanych], about 2% of patients on the semicircular canal bony wall is not normal development, mild head trauma or barotrauma can lead to loss of continuity of bone wall. Cleft syndrome in half of the regulation of the signs and symptoms are usually accompanied. Symptoms include irritation or by the strong voice of intracranial pressure or middle ear pressure changes that occur when the stimulus vertigo or oscillopsia, chronic balance disorders, hearing loss,[link widoczny dla zalogowanych], etc.; and signs are included in the same time symptoms appear on the semicircular canal plane Eye and head position deviation. The mechanism of these symptoms have half of a lack of regulation of bone covering the membranous labyrinth, resulting in superior semicircular canal membranous labyrinth prone to deformation. It is believed that. Round window or oval window inward pressure to change. Will lead to hole out at the prominent membranous labyrinth. Ampulla of semicircular canal caused arising from the ampulla of displacement: rather membranous labyrinth is inward conflict,[link widoczny dla zalogowanych], resulting in the displacement of the ampullary crest. Stimulation of bone conduction for the identification of sensorineural hearing loss and hearing loss. It is believed that. By bone conduction of vibration energy through the bone to the inner ear full: there may be another mechanism at work. Removal of the rat skull, brain tissue placed on the surface of the vibration can lead to auditory brainstem response (ABR). Guinea pigs and gerbils had a similar phenomenon. Experimental ossicular chain by eliminating the inertia mechanism and the occlusion effect. Did not significantly change the bone response. Reduce the volume of liquid within the cranial cavity may cause increased bone conduction ABR threshold. The air conduction ABR threshold of no effect. ... Therefore,[link widoczny dla zalogowanych], the classic bone conduction mechanism should be amended. That should include the non-excited channel cochlear bone conduction: the vibrator placed on the skull, the skull bone vibrations may cause the contents (brain tissue and cerebrospinal fluid) of the audio sound pressure, the pressure exerted by the conduction through the fluid channel to the inner ear fluid [51 . The following evidence supports the SSCD ~ I from conductive hearing loss: (1) ossicular chain intact tympanic probe, there is no conductive hearing loss can lead to middle ear disease: (2) leads to the normal acoustic reflex thresholds and abnormal VEMP and the existence of the middle ear drop lesion does not match; (3) surgical repair, the air - bone gap disappears. Superior semicircular canal cleft syndrome may also occur into the inner ear-derived conduction
