功能性内镜鼻窦手术前后Ⅱ型慢性鼻窦炎患者鼻腔共鸣特性分析

Clinical Analysis of Nasal Resonance Features before and after FESS in Patients with Chronic Sinusitis TypeⅡ

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一能量，分别统计各部位0～999Hz（FR1）、1000～1999Hz（FR2）、2000～2999（FR3）、3000～4000Hz（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 Ⅱ chronic 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〈0.00l）. 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.
