Tube Troubles. The Eustachian tube is a small passageway from your inner ear to the back of your nose, and plays an important part in the hearing process. Every time you swallow, yawn, or blow your nose, the Eustachian tube opens and allows air to pass from the middle of your ear to the back of your nose. This process equalizes the pressure in our ears, and prevents the eardrum from bulging in or out too much.
Oromotor dyspraxia, also called verbal apraxia or apraxia of speech: Makes it difficult to coordinate muscle movements needed to pronounce words. Kids with dyspraxia may have speech that is slurred and difficult to understand because theyâre unable to enunciate.
Aetiology. 1  Acquired apraxia/dyspraxia is usually due to disease affecting the left inferior parietal lobe, the frontal lobes or the corpus callosum. 2  Stroke and dementia are the most common causes but any disease affecting these areas of the brain, including tumours, can be the cause.
