OBJECTIVE: To compare the therapeutic effect of radiofrequency ablation and focused ultrasound in treatment of allergic rhinitis which was refractory to medical therapy, and to explore the reliable and safe surgical treatment. METHOD: Eighty-six perennial allergic rhinitis patients were divided randomly into two group. The radiofrequency ablation group included 40 patients and focused ultrasound group included 46 patients. A standard 0 to 10 visual analog scale (VAS) was used to assess the allergic symptoms therapeutic effect before and one year after treatment. RESULT: Allergic symptoms were improved in both two groups one year after treatment. The total VAS score in radiofrequency ablation group decreased from 31.35 +/- 6.16 to 14.16 +/- 4.83 and the total effective power of this group was 87.5% at the twelfth month after surgical. While the total VAS score in focused ultrasound group decreased from 32.86 +/- 5.45 to 21.91 +/- 8.58 and total effective power was 69.6% (all P < 0.01). CONCLUSION This study had demonstrated that the radiofrequency ablation and focused ultrasound appears to be an effective and safe tool for treating allergic rhinitis which was refractory to medical therapy. Compared to focused ultrasound, the radiofrequency ablation seemed to have a longer time therapeutical effect. While the focused ultrasound was more safe and little trauma, which made it possible to the repeated application.

Objective:To study the efficacy of Barbed reposition pharyngoplasty (BRP) combined with Han-Uvulopalatopharyngoplasty (H-UPPP) in surgical treatment of OSAHS patients.Methods:OSAHS patients admitted to our department from June 2021 to February 2022 who met the surgical enrollment criteria were divided into two groups by surgical procedure: H-UPPP operation group [Control group, 47 cases, including 42 males and 5 females, aged 18-64 (37.77±11.65)years, and H-UPPP+BRP group [Study group, 48 cases, including 45 males and 3 females, aged 23-60 (39.10±9.86) years]. The surgical efficacy 6 months after operation was retrospectively analyzed. Meanwhile, the relationship between the surgical efficacy and modified Friedman pharyngeal anatomical stages was analyzed. The postoperative pain VAS score at first 3 days and the incidence of foreign body sensation in pharynx after 6 months of operation were compared between the two groups. Statistical analysis was conducted by SPSS 23.0.Results:There were no significant differences in gender, age, BMI, Friedman pharyngeal anatomical stages, ESS score, AHI and LSpO 2 between the two groups, preoperatively ( P>0.05). There was significant difference between the two groups in ratio of cumulative time of oxygen saturation below 90% to total sleep time(CT90), preoperatively. Surgical efficacy of H-UPPP operation group was 48.9% (23/47), while H-UPPP+BRP operation group was 70.8% (34/48), which was statistically significant ( χ2=4.74, P=0.029). H-UPPP+BRP group seemed to have a higher surgical efficacy than H-UPPP group in patients with Friedman Ⅱb (87% vs. 61.9%) and Ⅲ stage (44.4% vs. 15%), but there was no statistically significant difference ( P>0.05). H-UPPP+BRP group had a higher pain VAS score in first three days ( t=-3.10, P=0.003), also had higher incidence of pharyngeal foreign body sensation after 6 months of operation ( χ2=4.727, P=0.030). Conclusions:In the surgical treatment of OSAHS patients, the overall efficacy of BRP combined H-UPPP surgery is higher than that of H-UPPP surgery alone. It may be more suitable for OSAHS patients with modified Friedman type Ⅱb and type Ⅲ stage.
