Upon examination of a suspected case of<unk> , a doctor can directly view the tympanic membrane with a light and observe that it vibrates with every breath taken by the patient. A tympanogram may also help with the diagnosis.<unk>  is likely if brisk inspiration causes a significant pressure shift.<unk>  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. When misdiagnosis occurs, a decongestant medication is sometimes prescribed. This type of medication aggravates the condition, as the Eustachian<unk>  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. The misdiagnosed patient may also have<unk> s surgically inserted into the eardrum, which increases the risk of ear infection and will not alleviate<unk> . If these treatments are tried and failed, and the doctor is not aware of the actual condition, the symptoms may even be classified as psychological. Incidentally, patients who instead suffer from the even rarer condition of superior canal dehiscence are at risk for misdiagnosis of<unk>  due to the similar autophony in both conditions.
