ABSTRACT:
A medical teaching apparatus enables medical students, physicians, and surgeons to hone their skills of examination and surgical procedures upon the human ear. This includes the tympanic membrane and also some structures of the human middle ear such as the malleus, the incus, and the stapes bones. The apparatus is in the form of a "book" like structure including two generally rectangular plates which can be joined by a hinge. When the book sections are closed one upon the other, abutting surfaces mate to sandwich a sheet of film therebetween that simulates a patient's tympanic membrane. Each of the sections has correspondingly sized and shaped openings through which a surgeon can insert an examination instrument or different types of surgical probes and instruments. One of the book sections carries an insert plug that reproduces structure of the patient's middle ear.
