 At their first visit, the ENT- surgeon will control the status of the eardrum and middle ear by otomicroscopy. The extent of pneumatisation atelectasis and fluid in the middle ear will be evaluated in addition to the state and position of the tympanic membrane. With a nasal endoscope the condition of Rosenmullers fossa and the function of torus tubarius will be examined. The latter is controlled by asking the patient to equalize pressure while the scope is in the nasopharynx, and the opening of the torus can be seen. The patients and controls are interviewed structurally for symptoms related to middle ear and temporal bone disease.
