In the treatment of olfactory disorders, we should first start our processes by questioning the current olfactory disorder of the person in detail. Information about the cause of the disease is obtained with many questions such as the severity of the olfactory disorder, how it occurs, whether it is continuous or intermittent, how long it has been present. After this preliminary preparation, a detailed ENT examination is performed. In this ENT examination, olfactory field endoscopy should also be performed. The olfactory field endoscopy informs us that the olfactory disorder is a conductive loss. After the ENT examination, it is necessary to perform the Odor Threshold, Odor Discrimination, Odor Identification and Odor Hedonic Scale tests. All these tests about smell inform us about the type of olfactory disorder. Then, the phase of imaging the olfactory area with tomography and evaluating the volume of the olfactory bulb with MR begins. At these stages, if it is not clarified whether the olfactory disorder is due to a conductive type or a nervous problem, it is evaluated whether the signal reaches the olfactory regions in the brain with the olfactometer, in which the electrical activity of the olfactory stimulus is recorded. Functional MR is also used for mapping.
