目的:探讨鼓室硬化在慢性化脓性中耳炎中的发生率、听力下降类型及听力下降与硬化灶部位和程度间的关系。方法:回顾性分析101例行手术治疗的慢性化脓性中耳炎患者的资料,所有患者均有完整的病史及耳鼻咽喉科体检,均行纯音测听检查,术中病灶均有详细记录。结果:慢性化脓性中耳炎患者鼓室硬化发生率为35.64%,大部分患者(77.78%)长期干耳,听力曲线为传导性聋。鼓膜硬化者中92.86%的患者气骨导间距小于40dB,而鼓膜与鼓室均有硬化者中45.45%的患者气骨导间距大于40dB。结论:鼓室硬化的听力损失与硬化灶的部位和程度直接相关。
Objective: To investigate the incidence of tympanosclerosis in chronic suppurative otitis media, the type of hearing loss and hearing loss and the relationship between the site and degree of sclerosis. Methods: The clinical data of 101 patients with chronic suppurative otitis media who underwent surgery were retrospectively analyzed. All patients had a complete history and otolaryngology examination. All patients underwent pure tone audiometry. All the lesions were recorded in detail. Results: The incidence of tympanosclerosis in patients with chronic suppurative otitis media was 35.64%. The majority of patients (77.78%) had long-term dry ears and the hearing curves were conductive deafness. 92.86% of tympanic sclerosis patients with tracheal spacing less than 40dB, while the tympanic membrane and tympanic sclerosis in 45.45% of patients with more than 40dB air-conduction spacing. Conclusion: Hearing loss of tympanosclerosis is directly related to the site and degree of sclerosis.
