Normally, swallowing causes a little click or popping sound in the ear. This occurs because a small bubble of air has entered the middle ear, up from the back of the nose. It passes through the Eustachian tube, a membrane-lined tube about the size of a pencil lead that connects the back of the nose with the middle ear.
A video tape with audio recording was made with an endoscope and microphone while the patient produced the popping sound by digital manipulation. Under reduced speed playback, it became obvious that the mucus bubbling through the TM perforation was the likely source of the pop-ping sound emanating from the ear canal. To test this assumption, a small step-strip patch was placed over the TM perforation.
