摘要
目的了解鼓室炎症对自体骨塑形听骨链重建术后听力的影响。方法 45例自体骨塑形听骨链重建术的患者,根据鼓室炎症轻重程度分为炎症轻组(25例)及炎症重组(20例)。炎症轻组鼓室黏膜充血、光滑、无增厚;炎症重组鼓室黏膜肥厚、粘连、肉芽增生。比较两组术前后的平均气骨导差。结果炎症轻组术后平均气骨导差比术前减少(17.87±7.11)dB,而炎症重组减少(9.65±5.13)dB,两组手术前后平均气骨导差值的差异有统计学意义(P<0.01)。结论鼓室炎症的轻重程度是影响术后听力的重要原因。
Objective To study the influence of tympanal inflammation on the hearing after ossicular chain reconstruction with autologous bone.Methods Forty-five patients undergoing ossiculoplasty were divided into 2 groups based on the severity of tympanal inflammation,and the average air-bone gap（ABG） was compared before and after operation.Of 25 cases with mild inflammation,the tympanal mucosa was congestive,smooth and no thickening;of 20 cases with severe inflammation,the tympanal mucosa was hypertrophic,adhesive and granulomatous.Results The postoperative ABG reduction was（17.87±7.11） dB in mild inflammation group and（9.65±5.13） dB in severe inflammation group.There was a significant difference in postoperative ABG reduction between both groups（P〈0.01）.Conclusion The severity of tympanal inflammation is the main cause of postoperative hearing.
