Open Access Guide to Audiology and Hearing Aids for Otolaryngologists Diagnostic Evaluation of Tympanic Membranes
نویسندگان
چکیده
The most common middle ear diseases are otitis media with effusion (OME), acute otitis media (AOM) and chronic suppurative otitis media (CSOM)). Diagnosing middle ear disease is based mainly on inspection of the tympanic membrane (TM) and indirect measurements of the status of the middle ear. (Tables 1, 2; Figure 1) To improve diagnostic accuracy in general practice the important factors are assessment of the position and transparency of the TM, and use of pneumatic otoscopy and/or tympanometry 1 .

Thus in a patient with otoscopic evidence of chronic otitis media, the object of taking a history is not to make the diagnosis but to assess the resultant disability and to plan management. Equally, if an audiogram is availab...
