ABSTRACT
Introduction Loss of olfactory function is often the first and only symptom of an acute COVID-19 infection. A persistent loss of smell is also an expression of a long-COVID syndrome. Those affected complain of a long-lasting loss of smell and often also of a distorted odor perception, which only occurs later in the course and can severely impair the quality of life. Material and Methods From March 2021, 22 patients with a subjective olfactory disorder after a COVID-19 infection were examined at the University Hospital Augsburg. The subjective olfactory ability was recorded, the SDI test was carried out to determine the olfactory function as well as a taste test and an endoscopy of the nose. The severity of the parosmia was examined using a questionnaire. The patients received smell training for at least 3 months. Another examination was carried out 4-5 months later. Results 12 of the 22 patients showed hyposmia and 10 normosmia according to the SDI test. 17 of the patients reported that they had developed parosmia, 5 patients had no parosmia. After carrying out the olfactory training, there was a significant improvement in the olfactory ability measured by the SDI test, the subjective assessment of the olfactory ability differed greatly from the value measured in the SDI. Summary The study shows the typical occurrence of parosmias in the course of postviral olfactory disorders, which occur almost regularly in the case of an olfactory disorder caused by COVID-19. The study also clarifies the importance of olfactory training in the treatment of postviral olfactory disorders and the importance of carrying out an objective olfactory test, since the subjective assessment of the patient often does not reflect the actual olfactory ability.
