考你流行病学资料来源了, 怕未?
鼓膜穿孔的原因有炎症和外伤,外伤具有意外性,所以其总体发病率较难统计,
就炎症引起的鼓膜穿孔来说,发病率较高,约在1%到10%之间。

Incidence of tympanic membrane perforation (TMP) in the general population is unknown. One survey found that that 4% of a population of Native American children had tympanic membrane perforation (TMP). [2] Another study found that 3% of children treated with ventilation tubes had the condition. [3] However, the incidence in the general population has not been studied. Even the exact number of surgical tympanic membrane perforation (TMP) repairs performed each year is unknown. Analysis of government statistics indicates that perhaps 150,000 tympanoplasties are performed per year in a population of 280 million.
