A Bit About Bostons. A cross between the English bulldog and the white English terrier, the Boston originated in Boston, Massachusetts in the late 19th century. Not larger than 25 pounds, the dog is muscular, alert and intelligent, and has an easygoing personality. That said, heart disease is the leading cause of death in this breed.
Premature babies are often more prone to infections that can cause deafness. They may also be born with severe jaundice or experience a lack of oxygen at some point. Both of these can cause deafness. In early childhood there is a range of things that can be responsible for a child becoming deaf. Infections like meningitis, measles and mumps can cause deafness. Ototoxic drugs, used to treat other types of infections in babies, can also be a cause.
This is why your ears pop. Sometimes people suffering from ETD get crackling noises in their ears or deafness. The deafness is usually temporary and is as a result of the normal flexible ear drum, or tympanic membrane, becoming stiff as a result of the increased pressure behind it. The ear drum is therefore unable to move when a sound wave hits it and so the sound is muffled when it is heard. The crackling is due to the mucus moving within the middle ear. It is the blockage of the Eustachian tube that causes pain in the ears when flying as the changes in air pressure make it difficult for the pressure across the ear drum to equalise. This causes the ear drum to be stretched, which is painful.
