METHOD FOR CORRECTION OF OLFACTORY DISORDER IN PATHOLOGY OF NOSE AND PARANASAL SINUSES Russian patent published in 2024 - IPC A61B5/02 A61K8/92 A61M15/08 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to otorhinolaryngology. It can be used for correction of olfactory disorder in pathology of nose and paranasal sinuses. Method consists in carrying out training of olfactory function with application of device for diagnostics and rehabilitation of olfactory disorders "ReviSmell" and application of 15 test aromas, which are used as essential oils: muscatel, pine, peony, eucalyptus, cloves, chamomile, mint, coffee, cinnamon, lavender, bergamot, lemon, balm, valerian, wormwood. Before the beginning of the treatment, the sense of smell is assessed by supplying 15 test aromas to the nasal mask on the above device using a scenario – diagnostics with patient immersion into virtual reality using virtual reality glasses. When determining more than 13 test aromas and their correct identification with a visual analogue and response time ≤ 5 seconds, normosmia is established. If none of 15 test aromas are recognized, anosmia is diagnosed, in other cases – hyposmia. If the patient reports an unpleasant smell of the test aroma, parosmia is diagnosed. If observing the olfactory disorder, the correction is carried out on the ReviSmell apparatus using the rehabilitation scenario. In the course of correction, 15 test aromas are used, wherein the sequence and time of supply of aromas depends on the previous assessment of smell. During the first two weeks of treatment, 15 test aromas are used, the first to select are those aromas that the patient correctly recognized, assessed as pleasant, and the response time was equal to ≤ 5 seconds during diagnostics. Then one uses aromas which the patient misidentified but rated as pleasant, and the response time is ≤ 5 seconds. Further, it is proposed to recognize aromas that the patient identified correctly, assessed as pleasant, but response time ≥ 5 seconds. Finally, the patient is offered aromas which he incorrectly identified and referred to as unpleasant. Correction of olfactory disorder is considered to be effective if the patient is able to identify more than 13 test aromas, and the response time is equal to ≤ 5 seconds. Duration of correction ranges from 14 days to 1, 3 and 6 months depending on patient’s ability to identify test aromas and response time spent on identification.

EFFECT: method is easy to use, improves patient’s quality of life.
