Clinical application of antibiotics and other drugs to reduce inflammation in the middle ear, inflammation secretion exudate reduce lead to pus exudate reduce, local pus form dry scab, is otitis media soon to be good performance, but not completely good performance. 2, otitis media scab does not mean that otitis media is good, otitis media scab is probably otitis media secretion discharged obstruction, lead to pus in the local crust and block the ear canal. Not only is otitis media not good performance, but may be the performance of otitis media aggravation. Because otitis media secretions can not be discharged in a timely manner, the accumulation of inflammation in the tympanic cavity will lead to further aggravation of inflammation, otitis media is more difficult to cure. Repeated, large amounts of pus accumulation is easily accompanied by other bacterial infections, leading to the possibility of patients with cranial, internal and external complications, rather unfavorable to the disease.
