| Objective: To observe the clinical efficacy of olfactory training which divided into scented and foul mixed training group and perfume training group in patients with olfactory disorder(after upper respiratory tract infection and after trauma).Methods:From December 2016 to November 2018,72 patients with olfactory dysfunction after trauma or upper respiratory tract infection were treated in Fir st Affiliated Hospital of China Medical University.According to the different tr aining methods,it is divided into “scented and foul mixed training group” and“perfume training group”,each with 36 cases.In this study,including 30 males and 42 females,had an average disease duration of 13.58±13.51(3-66)month s and an average age of 46.97±15.65(20-80)years.In the "perfume training gr oup",there were 12 males and 24 females with an average disease duration of13.58±13.51(3-60)months and an average age of 47.6±16.68(20-80)years o ld.In the "scented and foul mixed training group",there were 18 males and 18 females with an average disease duration of 11.18±11.10(3-66)months and a n average age of 46.33±14.53(20-79)years old.Perfume training group was m ade up of four completely different perfumes purchased by the patient.scented and foul mixed training group adds a rotten smell(rotated meat)and a burnt smell(scorched cotton)to the patient's own purchase of four completely diffe rent perfumes.Both groups were trained for 3 months.TDI scores and VAS scor es for fumes and odor were performed before and after treatment.It is effective that TDI score after training is improved by 6 points before training.Statistical analysis was performed using t test,Wilcoxon signed rank test,and Fisher ex act probability method(? = 0.05).Results: The training was completed in 72 cases.In the perfume training group and the scented and foul mixed training group,50.00%(10/20)and 9.09%(2/22)of the foul-sensing recovery were significantly weaker than the scent,and Fisher's exact probability P = 0.006.(P < 0.05),the difference was statistically significant.The effective rate of the perfume training group was 55.56%(20/36),The TDI score beforetraining was 6.50±8.32,and the TDI score after training was 15.00±13.50.The TDI scores before and after treatment were significantly different after paired sample t test(P < 0.05).The effective rate of the scented and foul mixed training group was61.11%(22/ 36),The TDI score before training was 9.21±10.68,and the TDI score after training was 18.42±14.14.The statistical method was the same as above,and the difference before and after treatment was statistically significant(P < 0.05).The difference of TDI scores between the two groups before and after treatment was compared with Wilcoxon signed rank test(P = 0.971)(P > 0.05).There was no significant difference between the two treatment groups.Conclusions: The training materials used in this study are low in cost,convenient and flexible,and the patient has high compliance and a lighter treatment burden.Th e recovery of foul perception in patients with “scented and foul mixed training gro up” is better than “ perfume training group ”.Both groups had a certain therapeutic effect on olfactory disturbance,and there was no significant difference in curative effect.Less unpleasant odors,such as burnt smell and gas,play a decisive role in th e safety of patients.Therefore,it is recommended to add rotten smell and burnt sm ell in the future olfactory training method. |
