Abstract

Olfactory disorders are not rare and affect quality of life in patients. The purpose of our study was to evaluate the outcomes of an outpatient-based diode laser inferior turbinate reduction (ITR) in otherwise therapy-refractory olfactory disorder. In a prospective clinical investigation, 20 patients (7 male, 13 female, mean age 53.2 ± 15.34) with olfactory disorder and 10 patients (8 male, 2 female, mean age 52.5 ± 17.55) without olfactory disorder underwent ITR under videoendoscopic control with a continuous diode laser in “contact” mode after topical anesthetic preparation. Treatment efficiency was assessed before and 2 months after surgery. Subjective nasal airflow (NA) and the olfactory function were rated by means of visual analogue scales (VAS). Olfactory function was assessed using the “Sniffin’ Sticks” test battery. VAS showed very low median values for intraoperative pain (0) [0–1.20] and high postoperative patient satisfaction (8) [5–9]. After 2 months there was no significant improvement of objective olfactory function as measured by the TDI score (threshold, discrimination and identification). The VAS displayed a slight significant improvement in the group of patients with olfactory disorder from 2.95 to 3.65 (P = 0.04). After 2 months, NA data revealed a statistically significant improvement of subjective VAS from 5.05 to 6.25 (P < 0.0005) and of objective NA from 353.77 to 443.50 (P = 0.007) as measured by rhinomanometry in both groups. Outpatient diode laser ITR represents an effective option providing recovery by NA improvement but not a significant improvement of the olfactory function.
