What happens if the semicircular canals are damaged?
Damage or injury to the semicircular canals may be twofold. If any of the three separate pairs do not work, a person can lose their sense of balance. A loss of hearing may also result from any damage to these semicircular canals.
What is lateral semicircular canal dysplasia?
Background and Objectives: Dysplasia of lateral semicircular canal (LSCC) is the most common inner ear malformation, because LSCC is the last single structure to be formed during inner ear embryogenesis.
What does the lateral semicircular canal do?
The lateral canal detects angular acceleration of the head when the head is turned and the superior and posterior canals detect vertical head movements when the head is moved up or down.
What causes cochlear malformation?
This ano- maly is caused by a developmental arrest during the seventh week (11) or a developmental arrest of the ear between days 58 and 70 of gestation, which causes the interruption of cochlear development at one and a half turns producing this deformity and being associated with complete deafness and vestibular …
Can SSCD cause headaches?
This can cause headaches, head pressure, and ultimately damage the optic nerve and vision.
How does semicircular canals affect balance?
When your head moves around, the liquid inside the semicircular canals sloshes around and moves the tiny hairs that line each canal. These hairs translate the movement of the liquid into nerve messages that are sent to your brain. Your brain then can tell your body how to stay balanced.
What is in the vestibular apparatus?
vestibular system, apparatus of the inner ear involved in balance. The vestibular system consists of two structures of the bony labyrinth of the inner ear, the vestibule and the semicircular canals, and the structures of the membranous labyrinth contained within them.
What causes inner ear malformation?
Inner ear malformations can be associated with both hereditary and nonhereditary SNHL. Sporadic malformations may occur by presumed localized teratogenesis during the early development of the inner ear as a result of putative toxic insults during the first 8 weeks of gestation. The cause is rarely determined.
Can SSCD cause fatigue?
MS and SSCD share symptoms, such as fatigue, acquired nystagmus (uncontrollable rapid eye movements), migraines, vertigo, and balance loss—and I was experiencing all of these.
