Wind in the ears from ear-nose ventilation is usually caused by dysfunction of the Eustachian tube or perforation of the eardrum. 1. Eustachian tube dysfunction: Eustachian tube dysfunction is usually caused by congestion and edema of the mucous membrane around the Eustachian tube or inflammation of the mucous membrane. Since the Eustachian tube is in the middle of the ear and the nose, when inflammation of the Eustachian tube occurs, it may lead to low-frequency tinnitus, and the patient may experience the discomfort of wind in the ear. Common causes of Eustachian tube dysfunction include allergic rhinitis, acute rhinitis, acute upper respiratory tract infections and nasopharyngeal inflammation. 2. Perforated eardrum: If the eardrum is ruptured and perforated due to external force or inflammation, the patient will experience windy ears when blowing nose or sneezing. If the patient has the above symptoms, it is recommended to go to the hospital in time for an examination of the eardrum and the eustachian tube, so as to make a clear diagnosis and then standardize the treatment under the guidance of the doctor.
