The eustachian tube can’t open itself. It’s a passive structure that sits closed by default, and the only thing that opens it is a muscle bolted directly onto the bone you adjust every day.
This episode breaks down the mechanism after Dr. Anthony sat through a live dissection from Anatomy Trains on head and neck anatomy, and one section stopped him cold: the tensor veli palatini, the eustachian tube, and the pterygoid muscles, all packed into a few millimeters around the pterygoid plates of the sphenoid.
What’s covered:
-
Why the eustachian tube is closed at rest, not open until something clogs it, and why every recurring ear infection is a tube that isn’t opening enough
-
The tensor veli palatini: it originates on the sphenoid, is woven into the wall of the tube itself, wraps around the hamulus like a pulley, and fans into the soft palate. One muscle, two jobs.
-
Why a child’s flat, horizontal tube plus a compressed sphenoid and narrow palate is two strikes before anyone’s touched the kid
-
The shared nerve supply between the tensor veli palatini and the tensor tympani, and what that means for tinnitus, specifically the clicking or arrhythmic kind
-
Why TMJ patients so often report ear fullness and ringing, and why ENTs have started sending Dr. Anthony referrals calling it a jaw issue instead of an ear issue
-
The adjusting order Dr. Anthony actually uses: occiput and OA clearance, sphenobasilar motion, category one versus category two, pterygoid and sphenomandibular contact points, disc tracking, and why this needs a corrective phase of care, not two visits
-
The hard line on what cranial work does and doesn’t promise for ear infections, tinnitus, and vertigo, and why vertigo runs a different mechanism and shouldn’t get lumped into this conversation
The takeaway: the sphenoid and palate aren’t optional in these cases. They’re the reason you can help a patient nobody else could.
