Efficacy of balloon dilation in the treatment of symptomatic Eustachian
tube dysfunction: One year follow-up study.
Tube Dysfunction (ETD) is a blockage of the narrow tube that connects the throat to the middle ear and helps the ears drain fluid and equalize pressure.
CSF leaks results from a communication way that takes place between the subarachnoid space, the mastoid air cells, the middle ear, the petrous apex air cells, and finally either the Eustachian
tube (ET), the surgical incision, or a tear in the tympanic membrane [7-10, 12-17].
Dysfunction of the Eustachian
tube is the most common reason for patients visiting and seeking treatment at ENT (Ear, Nose and Throat) departments worldwide.
6) The Eustachian
tube joins middle ear and nasopharynx and maintains the pressure equilibrium.
In this study, during the two year follow-up, only one patient with poor Eustachian
tube function succumbed to otitis media recurrence because of persistent postoperative tympanic negative pressure.
Then when the secretions of the nose are swept into the Eustachian
tube and middle ear or the sinus drainage pathways and then to the sinuses or into the trachea and bronchi and then the lungs, we see the clinical manifestations of acute otitis media, sinusitis, or pneumonia.
tube is the narrow tube that connects the middle ear to the throat - in adults it is approximately 3-4cm long.
tube function is assumed to play an important role in the aetiology of this disease.
The primary cause of recurrent middle ear infections is thought to be a dysfunction in the Eustachian
tube, a narrow tube that extends from the middle ear to the nasopharynx.
This structure begins to regress during the second trimester leaving four remnants: the Eustachian
valve (EV), the Thebesian valve, Chiari network and the terminal crest.
I doubt that any quantity of zinc would change eustachian
tube function in a clinically meaningful way.
