Tensor veli palatini and tensor tympani muscles: Anatomical, functional and symptomatic links

A Conceptual Study on Kaphaja Shiroroga with Special Reference to Sinusitis

“…The tensor muscle of the soft palate (TVP) dilates the ET lumen, but is also considered a masticatory muscle, as it is active during chewing, swallowing (acting on velopharyngeal movement) and phonation, orienting the tube inwards [2,3,10,11].…”

“…10 The TVP consists of an external and medial portion, the first of which originates from the spine of the sphenoid bone, the navicular fossa, the tensor tympani muscle and the lateral edge of the sulcus sphenoid. The medial portion comes from the middle third of the posterior-medial cartilage wall of the tube; the two areas descend and converge on the pterygoid halumus forming a strong tendon that curves around this process and is inserted horizontally into the soft palate as palatine aponeurosis.10 The TVP works closely with the tensor tympani muscle (TT), sharing the same innervation drivers.10 Its lateral surface is in direct contact with the surface of the anterior superior pterygoid medial muscle.6 With age, its strength declines with a change in its force vector and reduction in its range of motion [12].…”

“…The tensor tympani (TT) is a thin muscle, located outside the middle ear and along the tube, and is anchored to the sphenoid bone and the osseous portion of the tube; its distal tendon inserts on the malleolus in the upper, middle ear, involving the stirrup and the stapedius muscle [4,10,14]. Its contraction assists and is simultaneous with the TVP, pulling the malleolus to dampen eardrum vibrations while swallowing and during mastication [14].…”

“…Its contraction assists and is simultaneous with the TVP, pulling the malleolus to dampen eardrum vibrations while swallowing and during mastication [14]. There is a fascia link between the TT and the TVP [10]. It is innervated by the mandibular branch of the trigeminal nerve [14].…”

Terapia com placa oclusal com e sem guias anteriores de desoclusão em pacientes com disfunção temporomandibular e zumbido subjetivo

“…A literatura traz controvérsias tanto a respeito dos mecanismos envolvidos na produção dos sintomas auditivos em portadores de DTM (CASALE; RINALDI; SALVINELLI, 2005;KOMORI, 1986;LACOUT et al, 2005;MYRHAUG, 1964;PASCOAL et al, 2001;PENKNER et al, 2000;RAMIREZ ARISTEGUIETA et al, 2010;SALVINELLI et al, 2003;SCHMIDT et al, 1998), como sobre o efeito do tratamento odontológico na resolução desses (ANGELI et al, 1999;ANGELI et al, 2003;BJÖRNE, 2007;FELÍCIO et al, 2008;GIORDANI;NÓBILO, 1995;GUTIÉRREZ et al, 2001;SOBHY et al, 2004;ERNBERG, 2006;WRIGHT, 2007; WRIGHT; BIFANO, 1997). A expectativa dos profissionais que atuam nessa área é de que a sintomatologia auditiva melhore e, até mesmo desapareça após tratamentos como o uso de placas oclusais e/ou adequação da oclusão (FELÍCIO et al, 1996).…”
