OBJECTIVE

To study the effectiveness of TES in the area of the olfactory nerve in patients with olfactory dysfunction.

PATIENTS AND METHODS

Treatment of 41 patients with post-infectious hyposmia aged 18—71 years (30 women, 73.17%; 11 men, 26.83%) was performed. The Russian version of the Sniffin’ Sticks test (RVSS) was used to assess olfactory thresholds. TES was carried out with an average current of 2.5 mA, a session duration of 30 minutes and a treatment course of 10 days.

RESULTS

Olfactory index of patients with olfactory impairment after TES therapy of the olfactory nerve has improved by 1.5 times. TES has resulted in improvement of odor thresholds in 73% of cases. Significant improvement of olfaction and increase of RVSS indices by 50% or more have been determined in 25% of patients. Improvement of odor perception did not depend on the age and sex of patients.

CONCLUSION

TES therapy is an effective method of treating olfactory dysfunction and can be used in comprehensive therapy of olfactory disorders.
