Abstract

Background: This study assessed the eustachian tube (ET) function in adult patients with chronic rhinosinusitis (CRS) using tympanometry and nasal endoscope.

Materials and methods: This was a hospital-based cross-sectional study conducted for 9 months. All participants underwent endoscopic evaluation of the pharyngeal end of their ETs, and the middle ear function was assessed using tympanometry. Endoscopic findings were graded based on a validated mucosal inflammatory endoscopic grading scale. Statistical analysis was carried out using SPSS version 24.

Results: A total of 102 CRS patients and age- and sex-matched controls were recruited. Tympanograms suggestive of eustachian tube dysfunction (ETD) types B and C were found among 7.8% and 12.8% of the right and left ears of the CRS groups, respectively. Mucosal inflammatory endoscopic grade that is diagnostic of ETD Grades 3 and 4 was found among 24.5% and 38.2% of the right and left ET of CRS cases, respectively.

Conclusion: CRS predisposes patients to anatomical and functional impairment of ET. The relationship between tympanometry and mucosal inflammatory endoscopic grading scale in detecting ETD among CRS patients showed a strong relationship. However, a combination of the two will improve the diagnosis of ETD by evaluating the ET function directly and indirectly.

慢性鼻窦炎患者咽鼓管功能障碍的鼓室测量及内镜诊断。
背景:本研究采用鼓室测量法和鼻内窥镜对成人慢性鼻窦炎(CRS)患者的咽鼓管(ET)功能进行了评估。材料和方法:这是一项以医院为基础的横断面研究,为期9个月。所有参与者都接受了鼻咽部内镜检查,并使用鼓室测量法评估中耳功能。内镜检查结果根据经验证的粘膜炎症内镜分级量表进行分级。采用SPSS 24版进行统计分析。结果:共招募了102例CRS患者和年龄和性别匹配的对照组。CRS组右耳和左耳分别有7.8%和12.8%的鼓室图提示B型和C型咽鼓管功能障碍。CRS右侧ET和左侧ET分别占24.5%和38.2%,内镜下粘膜炎性分级可诊断ETD 3级和4级。结论:CRS患者易发生ET的解剖和功能损害。鼓室测量法与粘膜炎症内镜分级法在CRS患者中检测ETD的相关性较强。然而,两者的结合将通过直接和间接评估ET功能来提高ETD的诊断。
