Structural factors that affect otitis media are temporal bone dysfunction often in association with hypertonicity of the which muscle?

• A. Sternocleidomastoid
• B. Masseter
• C. Trapezius
• D. Temporalis

Answer: (A)

Otitis media in this view is influenced by how the temporal bone moves and how that motion is restrained by surrounding muscles. The sternocleidomastoid often shows hypertonicity when temporal bone dysfunction is present. Because this muscle runs from the sternum and clavicle up to the mastoid process on the temporal bone, persistent tension can tug on the temporal region and alter the position and motion of the temporal bone. That altered motion can impair the function of the Eustachian tube, hindering drainage from the middle ear and contributing to fluid accumulation and infection. Relaxing and balancing the sternocleidomastoid can help restore more normal temporal bone mechanics and better Eustachian tube function. The other muscles listed are less directly connected to the temporal bone mechanics that influence otitis media; they affect jaw or shoulder regions more than the cranial mechanics governing middle-ear drainage.
