The present invention provides an apparatus and method for inserting a relatively compact hearing aid at least partially through the tympanic membrane using a simplified surgical procedure. The hearing aid includes a microphone, an amplifier, and at least one speaker that can be assembled into a single enclosure for insertion through the tympanic membrane. The simplified surgical procedure can be performed on an outpatient basis and generally includes anesthetizing a portion of the tympanic membrane, forming an incision with a cutting instrument in the tympanic membrane and inserting the hearing aid at least partially therethrough. Incisions and placement of a tube in an tympanic membrane for car drainage is routinely performed in pediatric patients and combines low morbidity and good patient tolerability. The tympanic membrane restrains the hearing aid in position for at least a period of time. A power source, such as a battery, powers the hearing aid. Further, a receiver may be included with the hearing aid and can control the hearing aid from external sources. The receiver can control the amplified volume, receive sound transmissions from the opposite ear or a hearing aid in the opposite ear or receive personal communications.
