目的:观察低温射频等离子刀治疗慢性肥厚性鼻炎对鼻气道阻力的影响。方法:应用主动性前鼻测压法,测定82例慢性肥厚性鼻炎患者低温射频等离子术术前及术后3、10个月的鼻气道阻力;并应用主观视觉10分评分表评定患者术前及术后3、10个月鼻开放感觉评分请况。结果:鼻炎组术前鼻气道阻力为(0.665±0.21)kPa/(s·L);术后3个月为(0.301±0.16)kPa/(s·L),10个月为(0.391±0.24)kPa/(s·L);术后3个月和10个月分别与术前比较,差异有统计学意义(均P<0.01)。术前主观鼻开放感觉评分为7.5±1.5,术后3个月为2.0±2.0,10个月为3.0±2.5,术后3个月和10个月分别与术前比较,差异亦有统计学意义(均P<0.01)。结论:低温射频等离子术治疗慢性肥厚性鼻炎可显著降低患者的鼻气道阻力,同时可明显改善患者的主观鼻开放感觉。
Objective: To observe the effect of low temperature RF plasma knife on nasal airway resistance in patients with chronic hypertrophic rhinitis. Methods: Nasal airway resistance of 82 chronic hypertrophic rhinitis patients undergoing preoperative and postoperative 3, 10 months was measured by active anterior nasal pressure measurement. The subjective visual score scale was used to assess the patients’ Nasal opening sensory score before and after 3,10 months. Results: The preoperative nasal airway resistance in rhinitis group was (0.665 ± 0.21) kPa / (s · L), (0.301 ± 0.16) kPa / (s · L) in 3 months and 0.24) kPa / (s · L). There were significant differences between preoperative and postoperative 3 months and 10 months (all P <0.01). The score of preoperative subjective nasal opening sensation was 7.5 ± 1.5, 3 months after operation was 2.0 ± 2.0, and 3.0 months after 3.0 months. The differences were also statistically significant at 3 months and 10 months after operation Significance (all P <0.01). Conclusion: The treatment of chronic hypertrophic rhinitis by low-temperature radiofrequency plasma can significantly reduce the nasal airway resistance and improve the patients’ subjective nasal opening sensation.
