Abstract
Asymmetry of posterior palatine arches within quiet respiration may occur in two conditins. The one is termed “neurogenic” commenced on the occasion of the invasion of nerves innervated to the soft palae, such as Trigeminus, Facialis, Glossopharyngeus and of Vagus. The other one termed “myogenic” may develop when salpingopalatine muscle be affected in otitis media and in obstructive process of Eustachian tube.
