Hearing affected by cleft palate can usually be normalized. Hearing loss due to cleft palate may be due to exudative otitis media, in which the Eustachian tube does not open properly, and may return to normal after prompt and standardized treatment of the underlying condition. Exudative otitis media caused by fluid leakage from a cleft palate may result in a buildup of fluid in the tympanic cavity, which can affect hearing. Usually, it is necessary to make a hole in the tympanic membrane of the ear to drain the fluid inside the tympanic cavity, and then with anti-infection treatment, the hearing will gradually return to normal after the inflammation subsides. In children with cleft palate, the palatal tensor muscle is discontinuous, which does not exclude the possibility that the Eustachian tube cannot open normally. The Eustachian tube is a channel connecting to the outside world, and it will affect the hearing if it cannot open normally, so to solve the problem of the hearing caused by cleft palate, we can do the cleft palate surgery to restore the continuity of the palatal tensor muscle, and it is possible to restore the hearing through the surgical treatment. If the patient appears palate and affects hearing, it is recommended that he should seek medical treatment in time and standardize the treatment under the guidance of professional doctors.
