Patulous Eustachian Tube (PET) is a medical condition characterized by the abnormal openness of the Eustachian tube. Unlike the normal Eustachian tube, which opens and closes intermittently to regulate air pressure and drain secretions from the middle ear, a patulous Eustachian tube remains open most of the time. This can lead to a variety of symptoms, including autophony, where individuals hear their own voice or breathing unusually loudly.

Symptoms

The primary symptoms of Patulous Eustachian Tube include:

• Autophony
• Hearing one's own breathing
• A sensation of fullness in the ear
• Distorted hearing

These symptoms can be intermittent and may worsen with activities such as exercise, stress, or rapid weight loss.

Causes

The exact cause of Patulous Eustachian Tube is not always clear, but several factors may contribute to its development:

• Significant weight loss
• Pregnancy
• Neurological disorders
• Dehydration
• Hormonal changes

Diagnosis

Diagnosis of Patulous Eustachian Tube typically involves a combination of patient history, physical examination, and specialized tests. Otoscopy may reveal a moving eardrum in sync with breathing. Tympanometry and other audiological tests can help confirm the diagnosis.

Treatment

Treatment options for Patulous Eustachian Tube vary depending on the severity of the condition. They may include:

• Hydration and nasal saline drops
• Hormonal therapy
• Surgical interventions, such as the insertion of a ventilation tube or Eustachian tube plugging
• Use of nasal sprays to reduce the patency of the tube

Prognosis

The prognosis for individuals with Patulous Eustachian Tube varies. Some may experience relief with conservative treatments, while others may require surgical intervention. The condition can be chronic and may require ongoing management.
