Patients with blocked eustachian tubes are not recommended to travel by airplane because the air pressure changes greatly during take-off and landing, which may aggravate the blocked eustachian tubes and even cause tinnitus and hearing loss. Patients may become deaf within a short period of time, and sometimes the eardrum may be perforated, even with the flow of fluid, which may lead to the disease not being easily cured. Patients must avoid blowing their noses hard in life, especially when the eustachian tube is blocked after a cold, and need timely and symptomatic treatment. You can apply eucalyptus pinene enteric soft capsule to promote the outward drainage of secretions in the eustachian tube, and also apply drugs for rhinitis to reduce the blockage of the eustachian tube, because the nose and ears are connected, and the symptoms should be improved after symptomatic treatment.
