Abstract
|
|
|
Patulous eustachian tube (PET ), a disorder of the eustachian tube (ET ) occurs when the ET remains open in resting state. Patients with PET may experience symptoms such as aural fullness, autophony of voice or breathing sound. It is not challenging to diagnose PET due to the characteristic symptoms, which are relieved in the recumbent position.
The term “Masked PET” refers to a condition that symptoms of PET do not manifest until after middle ear surgery, as they were initially masked by conductive hearing loss. In this report, we present a patient who developed symptoms of PET after successful tympanoplasty, resulting in hearing improved. Based on this case, we suggest that all operators consider the possibility of the “masked PET” condition and explain it to the patient in advance to avoid situation of disappointment after surgery.
