Ear disorders are one of the most common diseases encountered in ear, nose and throat practice. This colour atlas presents a series of photographs illustrating the pathological conditions of external and middle ear. Images include both common and rare diseases, guiding students and clinicians through the basic conceptual knowledge to diagnosis and treatment. The photographs in the atlas have been obtained with a 4mm zero degree sinuscope allowing complete visual clarity of the entire tympanic membrane. Both the left and the right tympanic membranes are illustrated to enable a clearer understanding of the normal anatomy.
