1) These causes include abnormal eustachian tube positioning, underdeveloped cartilage within the eustachian tube causing increased collapsibility, abnormal skull base morphology causing a reduced sphenopalatine angle, and irregular tensor veli palatini and levator veli
palatini muscle position and function.
The dissection around the uvulus, soft palate muscles, maxillary tuberosity, medial pterygoid to elevate levator veli
palatini, sectioning of levator aponeurosis, osteotomy of GPA and more importantly elevation of nasal mucosa was not done.
The muscles that lift and stretch the soft palate up to meet the upper pharyngeal constrictor are the levator veli palatini and the tensor veli palatini muscles.
The action of the levator veli palatini and the tensor veli palatini muscles can best be felt at the beginning of a yawn.
The soft palate is lifted by the levator veli palatini and tensor veli palatini muscles from above with no relation to air flow.
In studying the velopharyngeal mechanism, the paired levator veli palatini muscles are generally considered the primary muscles of closure during speech (Kahane, 1986); however, this is an over simplification.
Muscle spindles in the human levator veli palatini and palatoglossus muscles.
The importance of this resides on the provoked neural "abnormal muscular reflex behaviors" influenced by chronic muscular-articular-mucosal deep pain toward all the skeletal muscles innervated by this pathway: tongue, intrinsic and extrinsic larynx, pharynx and palatal, tensor and levator veli palatini, some of the styloid process, facial, stapedius (possible stapedial intratimpanic mioclonus), tensor tympani, digastrics, mylohyoid and all the agonist muscles of mastication.
Functional anatomy of levator veli palatini muscle and tensor veli palatini muscle in association with eustaquian tube cartilage.
MRI showed (1) prominence of the left side of the tongue base in the oropharynx, best appreciated on T1-weighted images; (2) asymmetric T2 hyperintensity; (3) mild, diffuse enhancement of the left half of the tongue; and (4) atrophy of the left levator veli
palatini and tensor veli palatine muscles.
1) During swallowing, the lumen of the eustachian tube opens, and the toms tubarius elevates as a result of the combined action of three muscles: the tensor veil palatini, the levator veli
palatini, and the superior constrictor.
They originate on the floor near the pharyngeal ostium and expand between the tensor and levator veli
