Doctor tell me how do we hear. Because answering questions about your health is an important part of your doctor's services. The Minnesota State Medical Association presents doctor tell me here to ask the doctor your questions. Is Janice Hughes dead. Today your health questions will be answered by a doctor. A.J. Duvall an otolaryngologist from the University of Minnesota Medical School. Dr. Deval What roles do the outer ear the middle ear and the inner ear play in the hearing process. Well they all play an important part in the chain of hearing the outer ear is a somewhat protective mechanism. The part we call ear the pinna is pert is purely decorative. The middle ear is nature's High Fidelity amplifier and the inner ear which is in the base of the skull transmits changes the mechanical energy energy of sound waves into a nervous energy for transmission up to the brain where we interpret it.
Is there an actual opening through the ear into the head or is it blocked by the ear drum. It's blocked by the ear drum the ear canal is a blind SEC at the end of which normally is an intact eardrum. Why is the choir careful protection from the elements. It's a thin piece of cartilage covered by a skin and set somewhat away from the body and its warming influences and those who are making it become frostbitten will be very dangerous liable to fall off.

It keeps the ear canal lubricated and intercepts particles of dirt that may enter the canal and in which portion of the ear does this generally accumulate. It's formed in the outer part of the ear canal. How and when should you be removed. It should not be removed unless it

What about the use of toothpicks or hair pins to remove the ear wax. If they should never be used one should never put anything smaller than one's elbow in the year. Does this mean that access to X should always be removed when it has reached the outer part of the ear does the physician ever have to remove it if it reaches out to a point where you can take it away with the washcloth. Then it's not necessary the patient can do it it's only taken away there for for aesthetic purposes. If it's deep in the canal and plugs then the physician should take it out by digging it out where he can do so with direct visualization So the ear drum will not be injured. Or by washing it out with a syringe in water. How should a live insect in the ear be removed. One should first put in alcohol and drowned it and
