Eustachian tube dysfunction can be caused by a number of factors. Some common causes include the flu, allergies, a cold, and sinus infections. [6] In patients with chronic ear disease such as cholesteatoma and chronic discharge, studies showed that they have obstructive pathology at the ear side of the Eustachian tube.

Balloon Eustachian tuboplasty (BET) [1] is a minimally invasive procedure for the causal treatment of Eustachian tube dysfunction (ETD), an often-chronic disorder in which the regulation of middle ear pressure and the removal of secretions are impaired. The dysfunction often causes significant discomfort in affected patients and can trigger ...
The a risk of stretched or burst eardrums, can be reduced by any of a variety of methods to let air into or out of the middle ears via the Eustachian tubes. Sometimes swallowing will open the Eustachian tubes and equalise the ears. [13] Most of the methods are less likely than the Valsalva maneuver to cause collateral damage to the inner ear.
Patulous Eustachian tube is a physical disorder. The exact causes may vary depending on the person and are often unknown. [5] Weight loss is a commonly cited cause of the disorder due to the nature of the Eustachian tube itself and is associated with approximately one-third of reported cases. [6]
Immediate opening of the eustachian tube was observed in healthy subjects at 30-50 mbar pressure. In patients with chronic eustachian tube dysfunction, this opening could be registered in only 42% of the patients at 30 mbar and 58% at 50 mbar. [3] The results are usually interpreted as R values.
Otitis media with effusion (OME), also known as serous otitis media (SOM) or secretory otitis media (SOM), and colloquially referred to as 'glue ear,' [27] is fluid accumulation that can occur in the middle ear and mastoid air cells due to negative pressure produced by dysfunction of the Eustachian tube.
The EarPopper is a hand-held, battery-operated device that delivers controlled air flow through the nostril and can be used by the patient without medical supervision. Clinical studies have demonstrated the device's efficacy in the treatment of ear blockage caused by Eustachian tube dysfunction [ 1 ] and otitis media with effusion .
