文中报告二例镫骨耳硬化症同时伴有锤骨韧带骨化病例。例1经三次手术,听力获得提高;随访5年,气骨导差闭合。例2第一次手术后听力无明显改变。术后见有骨化的锤上韧带碎骨片,主要为新骨增生。就此二例讨论了形成锤上韧带骨化的可能性,认为以胚胎期残留软骨细胞成年后骨化的可能性较大。并提出对此种多听骨病变的处理应持慎重态度。
Reported in the article two cases of tarsal otitis media are accompanied by cases of ossicular ossification. Example 1 After three surgeries, hearing was improved; follow-up of 5 years, the closure of the air-conduction. No significant change in hearing after the first operation in Example 2. See the ossification of the hammer on the ligament bone fragments, mainly for new bone hyperplasia. This two cases discussed the possibility of forming ossification of the ligament on the hammer, that the embryonic residual chondrocytes are more likely to ossification in adults. And proposed that the treatment of such multi-heal bone lesions should be cautious attitude.
