This inflammation often begins when infections that cause sore throats, colds, or other respiratory or breathing problems spread to the middle ear. Why are more children affected by otitis media than adults? There are many reasons why children are more likely to suffer from otitis media than adults. First, children have more trouble fightinginfections. Another reason has to do with the childs eustachian tube. What are the effects of otitis media? Otitis media not only causes severe pain but may result in serious complications if it is not treated. An untreated infection can travel from the middle ear to the nearby parts of the head . Can anything be done to prevent otitis media? Specific prevention strategies applicable to all infants and children such as immunization against viral respiratory infections or specifically against the bacteria that cause otitis media are not currently available. How does a childs physician diagnose otitis media? The simplest way to detect an active infection in the middle ear is to look in the childs ear with an otoscope, a lightinstrument that allows the physician to examine the outer earand the eardrum. How is otitis media treated? Many physicians recommend the use of an antibiotic (a drug that kills bacteria) when there is an active middle ear infection. * *
