Alternobaric vertigo is a medical condition that is often experienced by divers and aviators. It is a form of vertigo that is caused by a difference in pressure between the two middle ears. This can occur during ascent or descent when the pressure changes are not equally balanced in both ears.
Causes[edit]
Alternobaric vertigo is caused by unequal pressure in the middle ears. This can occur if one ear equalizes pressure more efficiently than the other. The unequal pressure stimulates the vestibular system, which is responsible for maintaining balance in the body, leading to feelings of dizziness or vertigo.
Symptoms[edit]
The primary symptom of alternobaric vertigo is a sensation of spinning or dizziness. This can be accompanied by other symptoms such as nausea, vomiting, unsteadiness, and a loss of balance. The symptoms can occur suddenly and without warning, and can last for several minutes.
Diagnosis[edit]
Diagnosis of alternobaric vertigo is typically based on the patient's symptoms and their recent activities. If the patient has been diving or flying and experiences symptoms of vertigo, alternobaric vertigo may be suspected. Further tests, such as a physical examination or audiometry, may be conducted to confirm the diagnosis.
Treatment[edit]
Treatment for alternobaric vertigo primarily involves managing the symptoms and preventing further episodes. This can involve medications to relieve dizziness and nausea, as well as techniques to equalize pressure in the ears. In severe cases, surgery may be required to correct any underlying issues causing the pressure imbalance.
Prevention[edit]
Prevention of alternobaric vertigo involves ensuring that pressure is equalized in both ears during ascent and descent. This can be achieved through various techniques such as swallowing, yawning, or using specialized devices designed to equalize ear pressure.
