Understanding Patulous Eustachian Tube: Symptoms and Causes

Patulous Eustachian tube, also known as PET, is a medical condition characterized by the abnormal functioning of the Eustachian tube in the ear. The Eustachian tube is responsible for equalizing pressure between the middle ear and the outside environment, but in cases of PET, this tube fails to close properly.

Symptoms of patulous Eustachian tube can vary from person to person. Common signs include an echoing or booming sensation in the ear, autophony (hearing one's own voice or breathing sounds), and a feeling of fullness or pressure in the ear. Some individuals may experience a persistent dry cough or throat irritation due to the air passing through the open tube.

The exact cause of patulous Eustachian tube is not yet fully understood, but certain factors may contribute to its development. Weight loss, hormonal changes, pregnancy, and dehydration have been linked to the onset or exacerbation of the condition. Additionally, individuals with a naturally thin or narrow Eustachian tube may be more prone to experiencing PET.

1. Weight Loss: Rapid weight loss can lead to a decrease in fat surrounding the Eustachian tube, causing it to open more easily.
2. Hormonal Changes: Hormonal fluctuations can affect the muscle tone in the Eustachian tube, potentially leading to its abnormal functioning.
3. Pregnancy: During pregnancy, hormonal changes and increased blood volume may contribute to the development of patulous Eustachian tube.
4. Dehydration: Insufficient hydration can lead to changes in the consistency of the tissue surrounding the Eustachian tube, potentially affecting its function.

Diagnosing patulous Eustachian tube involves a thorough examination by an ear, nose, and throat specialist. The doctor may conduct various tests, such as tympanometry, audiometry, or nasal endoscopy, to assess the condition of the Eustachian tube and rule out other possible causes of the symptoms.

If you suspect you may have patulous Eustachian tube, it is important to consult with a medical professional for an accurate diagnosis and appropriate guidance. Understanding the symptoms and potential causes of this condition can help individuals seek the necessary medical attention and find relief from the discomfort it may cause.
