目的通过对慢性鼻窦炎I型患者行内窥镜鼻窦手术(endoscopic sinus surgery,ESS)前后鼻音及鼻腔阻力检测,探讨ESS后鼻腔鼻窦共鸣特性的改变及鼻腔阻力的变化特点。方法对资料记录完整的75例成人慢性鼻窦炎I型患者(1期38例,2期15例,3期22例),ESS前后使用鼻声图仪和鼻压计分别对鼻音和鼻阻力进行检测。结果I型1期患者术后1月鼻音和总鼻阻力与术前无明显变化;进一步研究发现,单侧上颌窦炎对鼻音有一定影响,手术后1月及3月基本恢复正常;单侧额窦炎或蝶窦炎对鼻音无明显影响。I型2期和3期患者术后1月总鼻阻力无明显改变,而鼻音较术前改善(P<0.05),但仍低于正常范围,术后3月术腔上皮化后,鼻音基本恢复正常。结论对于慢性鼻窦炎I型患者,ESS术后虽然总鼻阻力正常,鼻音仍在一段时间里表现异常。若术中过多破坏鼻腔、鼻窦正常结构,使鼻腔、鼻窦的共鸣特性发生了改变,可能对从事语音工作者(如播音员、外语及语言老师)的语音产生影响。
Objective To investigate the changes of nasal sinus resonance and nasal resistance after ESS by detecting nasal and nasal resistance before and after endoscopic sinus surgery (ESS) in type I patients with chronic sinusitis. Methods A total of 75 adults with chronic sinusitis type I (38 cases in stage I, 15 cases in stage 2 and 22 cases in stage 3) were recorded. Nasal sound and nasal resistance were measured before and after ESS . Results There was no significant difference in nasal tone and total nasal resistance between January and January after operation in type I patients. Further studies showed that unilateral maxillary sinusitis had some effects on nasal sounds, and returned to normal in January and March after surgery. Frontal sinusitis or sphenoid sinusitis no significant effect on nasal. There was no significant change in the total nasal resistance in patients with stage I and stage II after 1 month, while the nasal tone improved compared with that before operation (P <0.05), but still below the normal range. After 3 months of surgery, Back to normal. Conclusion For type I patients with chronic sinusitis, although total nasal resistance is normal after ESS, the nasal tone is still abnormal for some time. If too much intraoperative intraoperative destruction of the nasal cavity, sinus normal structure, the nasal cavity, sinus resonance characteristics have changed, may engage in voice workers (such as announcers, foreign languages and language teachers) voice impact.
