摘要： A proshesis apparatus method for implanting the apparatus, and method for controlling eustachian tube function includes an inflatable member dimensioned for at least partial receipt in a patient's eustachian tube. The inflatable member is operatively connected to means for selectively and volitionally inflating and deflating the member to close and open the eustachian tube. The inflating and deflating means preferably has a manually actuated pump disposed in subcutaneous tissue behind the ear and on the skull that communicates with the inflatable member. A reservoir means is placed in a surgically created mastoid cavity used for implanting the prosthesis. Alternatively, the reservoir means is formed as a portion of the pump. The eustachian tube function is controlled through selective inflation and deflation of the inflatable member to close and open the eustachian tube in a manner that simulates a normal, healthy eustachian tube. Further, the prosthesis apparatus allows volitional aeration of the middle ear space via control of eustachian tube opening and closing by a valve-like mechanism.
