“…If the tensor tympani and tensor veli palatine muscle dysfunction can generate otic symptoms each one separately, then the effects of an agonist co-working are anatomically more problematic. Barsoumian, Kuehn et al (1998) corroborate Lupin's 1969 findings and those later of Rood & Doyle (1978) findings by discovering in adult cadavers how the fibers of the most external zone of the tensor veli palatini muscle and the fibers of the tensor tympani are joined in the middle ear. (Rood, 1973;Williams et al, 1989;Prades et al, 1998).…”

SUMMARY:For many years otic symptoms have been closely observed in TMD clinical practice. This review includes trials that meet eligibility criteria in the field of otic symptoms diagnosed and treated by a stomatognathic focal point. The aim is centered on the implications of the debated cause-effect connection between otic symptoms and TMD offering a probable bond between the TMJ, ear and adjacent structures. The rationalization is based on an embryological and anatomical approach that offers explanations on the otic pathogenic mechanisms symptoms interconnected with TMD. The accompanying reciprocity among disciplines of odontology and otolaryngology is brought together by TMD and otic referred mutual symptomatology as is showed in multiple trials. This research is an attempt that targets the integration of these two health specialties in the diagnosis and treatment of this type of population.

“…We believe that histological embryonic and fetal preparations enable us to determine more exactly the arrangement of this connective formation. Rood and Doyle [1978], in addition to studying adult cadavers, observed a tendinous formation in the semicanal of the TT in a 5-month-old fetus. However, our conclusion is that this was not in fact the same formation since it was related to the cartilaginous part and not the membranous part of the tube.…”

The present study seeks to determine the main events that occur in the development of the tensor veli palatini (TVP). A light microscope was used on serial sections of 60 human specimens from weeks 6 to 16 of development. The TVP becomes visible in an embryo of 14.5 mm greatest length (GL; week 6) from a common blastema with the medial pterygoid muscle. In embryos of Carnegie stage 20 (week 7), the TVP is differentiated and relates to the anlage of the pterygoid hamulus. At week 8 of development, when the palatal shelves become horizontal, the presence of the anlage of the palatine aponeurosisis distinguished and is reached by the TPV. In an embryo of 30 mm GL, the chondrification nucleus of the pterygoid hamulus and the synovial bursa of the TVP are identifiable. At week 9, the TVP is continuous with the palatine aponeurosis. At week 13, a connective tissue lamina appears between the TVP and the intramembranous ossification center for the anterior process of the malleus, which we know as the goniale and interpret as an attachment of the muscle to the primary vertebrate jaw or incudomalleal joint. The TVP from its origin, innervation and relation to the goniale appears to be a muscle of mastication that, at the end of the embryonic period, reaches the palatine aponeurosis anlage and the mesenchyme of the auditory tube and specializes in the movements of the soft palate and the auditory tube.

“…A connection of the TT and TVP has been reported in man [Kostanecki, 1891;Eschweiler, 1899;Gaupp, 1912;Körner, 1942;Lupin, 1969;Proctor, 1973;Kamerer, 1978;Rood and Doyle, 1978], chimpanzee [Kostanecki, 1891;Gaupp, 1912], Hanuman monkey [Kostanecki, 1891;Gaupp, 1912], marsupials [Kostanecki, 1891;Gaupp, 1912;Edgeworth, 1914], bats [Kostanecki, 1891;Gaupp 1912] and pinnipeds [Kostanecki, 1891;Gaupp, 1912], but not in rhesus monkey [Doyle and Rood, 1980]. Although man and rhesus monkey both have a bony enclosure of the ME and AT, there is an interspecific difference regarding the structural relationship of the TT to the TVP.…”

Anatomical features of the middle ear and auditory tube (AT) in the house musk shrew, Suncus murinus, were examined by dissection and light microscopy. The tensor veli palatini (TVP) and tensor tympani (TT) have no connections with the wall or cartilage of the AT although they are connected by the intermediate tendon. None of the levator veli palatini (LVP) muscle bundles are attached to the AT. The salpingopharyngeus (SA) alone has its origin on the caudal edge of the tubal cartilage. The origin extends to the pharyngeal two thirds of the cartilage. The SA originates perpendicular to the AT and runs caudomedialward. Some SA muscle bundles intermingle with those of the palatopharyngeus to end on the dorsal wall of the pharynx. The observations provide no evidence that the TVP, LVP and TT have any role in AT function. The only muscle affecting the AT function in S. murinus is the SA, and it would be the AT dilator.
