【摘要】 目的:研究慢性中耳炎患者术后听力改善及其可能相关影响因素。方法:随访自2010年3月至2012年5月于本院耳鼻喉科进行慢性中耳炎手术的患者,将随访资料的病例行回顾性分析。结果:84例置入PORP病例术后气导听阈平均39.6±14.9dB,较术前,提高平均为13.9±13.2dB(P<0.001);平均气骨导差为20.5±8.5dB,气骨导差改变平均为8.8±10.7dB(P<0.001)。术后气导听阈改善在0.5 KHz,1KHz,2KHz三个频率上无明显差异(P>0.05),而气骨导差改善显示2KHz的改善不及0.5KHz,l KHz的气骨导差改善((P<0.001)。6例行颞肌筋膜鼓膜成型术病例术后气导听阈平均21.1±4.3dB,较之术前提高平均为13.6±7.2dB(P<0.05),平均气骨导差为11.1±4.2dB,气骨导差改变平均为6.7±4.2dB(P<0.05)。结论:置入PORP、颞肌筋膜鼓膜成型术均可明显改善听力。慢性中耳炎手术治疗效果令人满意,羟基磷灰石假体听骨对于听力改善效果肯定。更多还原

【Abstract】 Objective: To investigate the hearing improvement postoperatively in patients with chronic otitis media and its possible related factors.Methods: fromMarch2010toMay2012inourhospital otolaryngology,patientswithchronicotitismedia operation were followed up,the follow-up information line of cases were retrospectively analyzed.Results: 84 cases in PORP postoperative gas conduction audibility threshold average were 39.6±14.9 dB,theaverageincrease was 13.9a±13.2dB compared withpreoperative(P<0.001).A mean of bones guide was 20.5±20.5 dB,and poor bones conductivity was changed to an average of 8.8±10.7 dB(P<0.001).Postoperative air conduction audibility threshold at frequency of 0.5 KHz,1 KHz,2 KHz were no obvious difference(P>0.05),and poor bones guide at 2 KHz was less than that at 0.5 KHz and l KHz(P<0.001).In 6 temporalis fascia routine tympanic membrane forming cases,average air conduction hearing threshold was 21.1±4.3 dB,and increased 13.6±7.2 dB compared to the preoperative(P<0.05),the average of poor bones guide was 11.1±4.2 dB,the average of poor bones conductivity change was 6.7±4.2 dB(P<0.05).Conclusion: Placing PORP,tempo-ralis fascia tympanic membrane forming technique can obviously improve the hearing.Surgical treatment of chronic otitis media effect is satisfactory,and hydroxyapatite prosthesis auditory ossicle has the improvement effect on hearing.更多还原
