目的 :观察内窥镜下鼻腔鼻窦手术对咽鼓管功能的影响。方法 :运用MedsenZO 174声导抗仪对 10例鼻窦鼻甲手术患者 (鼻窦鼻甲组 )及 10例鼻中隔矫正术患者 (鼻中隔组 ) ,手术前及术后 1、3、5、10d的鼓室压、声顺、坡度等进行自动检测 ,观察其变化。结果 :术后 1、3d ,鼻窦鼻甲组鼓室压由术前 - 85 .5daPa分别降至- 14 8.0daPa及 - 139.0daPa ,分别与术前比较 ,其差异均有极显著性意义 (P <0 .0 1) ;鼻中隔组鼓室压由术前- 5 1.0daPa分别降至 - 111.5daPa及 - 96 .0daPa ,分别与术前比较 ,其差异亦有极显著性意义 (P <0 .0 1)。术后 5、10d两组鼓室压逐渐恢复至术前水平。手术前、后两组声顺、坡度无明显变化 (P >0 .0 5 )。术后 1、3d两组鼓室峰压点明显左移 ,术后 5、10d逐渐恢复至术前水平。结论 :鼻窦鼻甲手术和鼻中隔矫正术的术后早期均能引起咽鼓管阻塞 ,术后积极抗感染 ,正确、及时、定期清理术侧鼻腔 ,及早解除鼻腔压力 ,可减轻手术对咽鼓管功能的影响
Objective: To observe the effect of endoscopic nasal sinus surgery on eustachian tube function. Methods: Ten patients with nasal sinus surgery (nasal sinusitis group) and 10 patients with nasal septum surgery (nasal septum group) were treated with MedsenZO 174 acoustic conductivity meter. The tympanic pressure, Shun, slope, etc. for automatic detection, observe the changes. Results: The tympanic pressure in the pedicle of nasal sinus was decreased from -85.5daPa to -14.8daDa and -139.0daPa respectively at 1 and 3 days after operation, which were significantly different from those before operation (P <0.05) .0 1). The tympanic pressure in the nasal septum group was decreased to -111.5daPa and -96.0daPa from-1.0 to 1.0dPa in the nasal septum group, respectively, with significant differences (P <0.01) . The tympanic pressure gradually recovered to the preoperative level at 5 and 10 days after operation. Before and after the operation, there was no significant change in sound quality between the two groups (P> 0.05). At 1 and 3 days after operation, tympanic peak pressure point of the two groups shifted to the left, and gradually recovered to the preoperative level at 5 and 10 days after operation. Conclusion: Nasal sinus surgery and nasal septum corrective surgery can cause eustachian tube obstruction early postoperative positive anti-infection, correct, timely and regular removal of the nasal cavity, nasal cavity as soon as possible to relieve the pressure on the Eustachian tube function Impact
