[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.

It's worth noting that there hasn't been much comprehensive scientific research conducted to establish a clear correlation between most of the claimed potential causes and patulous eustachian tube disorder.

Upon examination of a suspected case of patulous Eustachian tube, a doctor can directly view the tympanic membrane with a light and observe that it vibrates with every breath taken by the patient.

Patulous Eustachian tube is frequently misdiagnosed as standard congestion due to the similarity in symptoms and rarity of the disorder.

Audiologists are more likely to recognize the disorder, usually with tympanometry or nasally delivered masking noise during a hearing assessment, which is highly sensitive to this condition.

This type of medication aggravates the condition, as the Eustachian tube relies on sticky fluids to keep closed and the drying effect of a decongestant would make it even more likely to remain open and cause symptoms.

[13] In extreme cases surgical intervention may attempt to restore the Eustachian tube tissues with fat, gel foam, or cartilage or scar it closed with cautery.

[14] Although a temporary solution, surgical ventilation tube placement in the ear drum has also proven to be an effective treatment option.
