A simple method for olfactory rehabilitation following total laryngectomy

Abstract

Purpose The aim of the study is to demonstrate the effectiveness of spraying odor particles using sinus rinse kits for olfactory rehabilitation in patients with total laryngectomy. Methods Olfactory rehabilitation was performed by applying four different odorant particles orthonasally using a sinus rinse kit pump for 30 min each day for a duration of 6 months. Olfactory function was evaluated by performing olfactory tests before the rehabilitation and at sixth month after the rehabilitation process. Results The average CCCRC score prior to olfactory rehabilitation was 2.28 +/- 0.79 (between 1.50 and 3.75), while it was 4.46 +/- 0.5 (between 3.50 and 5.25) out of a maximum score of 7 after 6 months of olfactory rehabilitation (p value < 0.0001) Conclusion Our results suggest that the use of sinus rinse kits is very simple, inexpensive, easy-to-use, and effective in providing passive olfaction to patients requiring olfactory rehabilitation.
