目的：探讨功能性内镜鼻窦手术（FESS ）对慢性鼻窦炎患者鼻腔共鸣特性的影响。方法对符合入选标准的50例成人Ⅱ型慢性鼻窦炎患者，应用“多通道语言分析系统”在FESS术前及术后三个月进行嗓音分析，采集发/i/时头、口、喉、胸四部位的嗓音共鸣频谱-能量，分别统计各部位0～999 Hz （FR1）、1000～1999 Hz （FR2）、2000～2999（FR3）、3000～4000 Hz（FR4）频段的嗓音共鸣能量分布，并与50例正常人比较。结果与正常人相比，Ⅱ型慢性鼻窦炎患者术前头部的低频能量较高，高频能量较低，差异有统计学意义（ P＜0．001）；术后三个月，头部的高频共鸣能量较术前提高，低频能量降低，但仍较正常人低，差异有统计学意义（P＜0．05），除口腔的FR3、FR4，术后喉腔的FR4及术前胸部FR4外，其他各频段共鸣能量与正常人相比差异无统计学意义（ P＞0．05）。结论慢性鼻窦炎患者FESS术后，嗓音的鼻腔共鸣低频能量降低，高频能量增强。

Objective To explore the effect of FESS on nasal resonance characteristics in patient with chronic sinusitis .Methods Detected 50 cases of adult patients with type Ⅱ chronic sinusitis ,and collected the date about the application of multi-channel voice analysis system that tested the pronunciation /i/before and three months af-ter FESS spectrum - energy distribution while compared with 50 normal subjects .Results Patients with type Ⅱchronic sinusitis before surgery compared with normal subjects ,the head of the low -frequency energy was higher , high-frequency was lower ,the difference was statistically significant (P<0 .001) .Voice energy distribution after three months compared with preoperative ,the head of the high-frequency resonance energy improved than preop-erative ,but still relatively low compared with the normal ,the difference was statistically significant (P<0 .05) . While the mouth ,chest and throat in addition to oral FR3 ,FR4 ,postoperative throat FR4 and preoperative chest FR4 ,other frequency -energy compared with normal subjects no significant change was not statistically significant (P>0 .05) .Conclusion For patients with chronic sinusitis ,low -frequency of the voice of nasal resonance de-creased ,and high-frequency increased after FESS .
