There may be the following reasons for high ear pressure: 1. External environmental factors, such as when patients are flying, especially when the plane rises or falls, or when doing diving sports or riding high speed trains may show elevated ear pressure. This is mainly caused by external environmental factors, which can be relieved in the short term. 2. Inflammatory factors, some patients have acute rhinitis, acute sinusitis, adenoiditis and other related inflammatory infections of the nasopharynx. Some patients have nasopharyngeal tumors, such as nasopharyngeal fibrovascular tumors and nasopharyngeal carcinoma, which compress the pharyngeal opening of the eustachian tube and lead to elevated negative pressure in the ear. In conclusion, if a patient has high ear pressure, it is recommended to go to the ENT department to improve otoscopy, pure tone hearing threshold, acoustic conduction resistance and other related examinations to determine what causes high ear pressure, so as to carry out symptomatic treatment and handling.
