THE OPEN EUSTACHIAN TUBE

THE OPEN EUSTACHIAN TUBE Abstract The eustachian tube is the only channel of communication between the nasopharynx and the middle ear for the purpose of equalizing the pressure of the external air and that contained in the middle ear. Unfortunately, this tube is also the most common avenue of approach of infection to the middle ear. It is a recognized fact that any pathologic nasal condition, such as acute and chronic rhinitis, hypertrophied turbinates and deviated septum and adenoids, predisposes to diseases of the middle ear (catarrhal deafness and acute and chronic suppurative otitis media and its complications). The middle ear is aerated only when the eustachian tube is opened, which takes place during the act of deglutition or phonation with a letter which tends to bring the soft palate upward and backward (ka). The tube is otherwise closed, so intended by nature to protect the middle ear from unnecessary exposure from the nasopharynx. One References 1.

Abstract

Abstract The eustachian tube is the only channel of communication between the nasopharynx and the middle ear for the purpose of equalizing the pressure of the external air and that contained in the middle ear. Unfortunately, this tube is also the most common avenue of approach of infection to the middle ear. It is a recognized fact that any pathologic nasal condition, such as acute and chronic rhinitis, hypertrophied turbinates and deviated septum and adenoids, predisposes to diseases of the middle ear (catarrhal deafness and acute and chronic suppurative otitis media and its complications). The middle ear is aerated only when the eustachian tube is opened, which takes place during the act of deglutition or phonation with a letter which tends to bring the soft palate upward and backward (ka). The tube is otherwise closed, so intended by nature to protect the middle ear from unnecessary exposure from the nasopharynx. One References 1.
