ABSTRACT

Background: There are evidence that repeated exposure to odorants produces relieve of some olfactory disorders.
Objetive: To observe the effects of olfactory training in patients with anosmia.
Material and Method: A prospective, descriptive and crosssectional study was done including 21 patients with olfactory dysfunction of posviral, postraumatic and idiopathic cause. They were divided into 2 groups of patients: 10 controls and 11 with olfactory disorders (three postraumatic, two idiopathic and six postviral). Training was done two times a day with four odors (alcohol, coffee, eucalyptus and rose essence). The Connecticut test was made at day 0 and 12 weeks.
Results: Seven patients (63%) showed improvement in cases compared to controls (one idiopathic, three posviral, and three postraumatic). Although there was no full recovery of olfactory function, they evolved from anosmia to mild or moderate hyposmia.
Conclusion: Olfactory training could be a tool for the management of patients with olfactory disorders. It is necessary to increase the number of cases and exposure time to the training and conduct a thorough analysis of each individual patient to demonstrate its effectiveness.
