目的:评价鼻中隔矫正术对双侧鼻腔的影响。方法:用鼻声反射和前鼻主动测压法对22例鼻中隔矫正术患者分别于术前和术后进行测试,其中3例行双下甲成形术,1例由于单侧鼻腔完全阻塞术前未能测出鼻声反射和鼻阻力数值,2例宽敞侧鼻腔行右下甲成形术,予以排除。最后纳入实验组狭窄侧鼻腔18侧,宽敞侧鼻腔16侧。记录鼻腔最小横截面积(NMCA)、NMCA至前鼻孔的距离(DCAN)、0～5cm鼻腔容积(NCV)和鼻阻力,进行统计学分析。结果:前鼻测压结果:偏曲侧鼻腔的吸气有效阻力术后比术前有明显下降(P<0.05),而宽敞侧吸气有效阻力术后较术前下降,但差异无统计学意义(P>0.05)。鼻声反射结果:偏曲侧鼻腔收缩前,0～5cmNCV和NMCA术后比术前明显增大,DCAN明显前移,3项指标均显示差异有统计学意义(均P<0.01)。宽敞侧鼻腔收缩前,0～5cmNCV术后比术前轻微增大,术后NMCA较术前轻微减小,DCAN较术前后移,3项指标的差异均无统计学意义(均P>0.05)。收缩后,0～5cmNCV术后比术前增大,差异有统计学意义(P<0.05);术后NMCA较术前轻微减小,差异无统计学意义(P>0.05)。结论:鼻中隔矫正术对偏曲侧鼻腔的功能和几何形态有明显改善,对侧宽敞侧鼻腔的通气功能和几何形态无明显恶化。
Objective: To evaluate the effect of nasal septum surgery on bilateral nasal cavity. Methods: Nasal reflex and anterior nasal active manometry were used to measure 22 cases of nasal septum corrective surgery before and after surgery, including 3 cases of double inferior formahy and 1 case of unilateral nasal obstruction Can be measured nasal reflex and nasal resistance values, 2 cases of wide side of the nasal line right inferior formazan, to be ruled out. Finally included in the experimental group side of the narrow side of the nasal cavity 18, 16 side of the spacious side of the nasal cavity. Minimal cross-sectional area (NMCA), distance from NMCA to anterior nares (DCAN), nasal cavity volume (NCV) and nasal resistance (0-5 cm) were recorded for statistical analysis. Results: The results of anterior nasal pressure test showed that the inhalation effective resistance of nasal nasal drops was significantly lower than that before operation (P <0.05), while the effective resistance of spacious side suction was decreased compared with that before operation, but the difference was not statistically significant Significance (P> 0.05). Nasal reflex results: Before the nasal constriction on the sinistral side, the levels of 0-5cm NCV and NMCA were significantly higher than those before operation, and the levels of DCAN were significantly advanced. All three indexes showed significant differences (all P <0.01). Before the wide side nasal constriction, 0 ~ 5cmNCV slightly increased after operation than before operation, postoperative NMCA decreased slightly compared with preoperative and postoperative DCAN, compared with preoperative and postoperative shift, the three indexes showed no significant difference (all P> 0.05 ). After constriction, the size of 0-5cm NCV was significantly higher than that before operation (P <0.05). The postoperative NMCA was slightly decreased compared with that before operation, with no significant difference (P> 0.05). CONCLUSIONS: Nasal septum corrective surgery significantly improves the function and geometry of the nasal nasal flexion side. There is no significant difference in the ventilatory function and geometry between the contralateral wide lateral nasal cavity.
