中耳炎是一种十分常见的诊断,抗菌素的应用已使本病合并症大为减少。但约有半数病例在其他征象消失后仍留有暂时性的听力缺损;还有10%左右的病例将遗留15分贝以上的永久性听力减退影响学习。近来发现,预防性的应用抗菌素可使高度易感儿的急性中耳炎发作频度大为减少。预防医学上的这一新可能性,提示摸清复发性中耳炎的流行病学情况可能具有实际意义。本文作者对165名患儿(男95,女70,4岁以下72%)进行12个 Otitis media is a very common diagnosis, the use of antibiotics has greatly reduced the complication of the disease. However, about half of all cases still have temporary hearing loss after other signs disappear. In addition, about 10% of cases will have permanent hearing loss effects of over 15 dB. It has recently been found that prophylactic use of antibiotics can greatly reduce the frequency of acute otitis media in highly susceptible children. This new possibility in preventive medicine suggests that finding out the epidemiology of recurrent otitis media may have practical implications. The authors of this study enrolled a total of 12 children (165 males, 70 females, 70% under the age of 4 years) in 165 children
