Otoscope Use and Flexible Pinna 5a An otoscope (not included) may be used to view each condition - insert the speculum into the ear canal with care. The flexible pinna may be manipulated to straighten the ear canal. Treat the ear with the same care you would a patient. Excess force may cause damage to the model. For best clarity of display of the conditions, we recommend setting the otoscope light to “off”. Sleep Mode The model has an automatic sleep mode which turns off all displays to conserve power. This is functional if either battery power or mains power is used. During sleep mode, the...

The handle of the malleus (blue arrow) runs from the lateral process at the top to the umbo in the middle of the membrane – the pars tensa. Posterior, i.e. to the left as you look at the image, is the long process of the incus (red arrow). Above the white bump at the top of the malleus handle - the lateral process of the malleus - is the so called attic region of the ear drum - the pars flaccida (green arrow).” “In Figure 2, I have removed...

EAR WAX (CERUMEN) The main clinical features are: • The very thin skin of the deep ear canal grows and migrates outward from the eardrum to the opening of the canal. This normally keeps the ear canal free of debris and maintains the resonance properties of the canal helping clarity and volume of hearing • Close to the outside of the canal are modified sweat glands that produce a liquid with anti bacterial and anti fungal properties • Further out are the fine hairs that produce a waterproof oily material Comment: The combination of skin, sweat and oil forms a thin film of “wax” which...
