Abstract
Introduction and objectives

Temporomandibular disorders are associated with symptoms such as tinnitus, vertigo, sensation of hearing loss, ear fullness and otalgia. The connection and dysfunction of the tensor tympani and tensor veli palatini muscles seem to be associated with the aforementioned symptoms. We seek to demonstrate and explain this connection through the morphometry of these structures.

Methods

We studied 22 paired blocks and 1 left side of human temporal bone. Digital measurements were made of the tensor tympani muscles and stapes.

Results

The average length of the stapedial muscle was 5.8mm (SD 0.61), and that of the tensor tympani was 19.69mm (SD 1.07). Anatomical connections were found between the tensor veli palatini muscles through a common tendon in all the samples.

Conclusions

There is a need for interdisciplinary management between physicians and specialised dentists in cases of craniofacial pain.

Resumen
Introducción y objetivos

Los desórdenes temporomandibulares están asociados con síntomas como tinnitus, vértigo, sensación de pérdida auditiva, plenitud ótica y otalgia. La conexión y disfunción de los músculos tensor del martillo (TM) y tensor del velo del paladar (TVP) parece estar asociada a esta sintomatología referida. Se busca demostrar y explicar esta conexión a través de la morfometría de las estructuras.

Métodos

Se estudiaron 22 bloques pareados y 1 izquierdo de hueso temporal humanos. Se realizaron medidas digitales correspondientes al TM y el musculo del estribo.

Resultados

La longitud promedio del musculo del estribo fue de 5,8mm (DE: 0,61) y la del TM fue de 19,69mm (DE: 1,07). En la totalidad de las muestras se halló conexión anatómica de los músculos TVP y TM a través de un tendón común.

Conclusiones

Se matiza la necesidad de un manejo interdisciplinario entre el médico y el odontólogo especialista en dolor craneofacial.
