Otitis media is a group of inflammatory diseases of the middle ear.[2] One of the two main types is acute otitis media (AOM),[3] an infection of rapid onset that usually presents with ear pain.[1] In young children this may result in pulling at the ear, increased crying, and poor sleep.[1] Decreased eating and a fever may also be present.[1] The other main type is otitis media with effusion (OME), typically not associated with symptoms,[1] although occasionally a feeling of fullness is described;[4] it is defined as the presence of non-infectious fluid in the middle ear which may persist for weeks or months often after an episode of acute otitis media.[4]Chronic suppurative otitis media (CSOM) is middle ear inflammation that results in a perforated tympanic membrane with discharge from the ear for more than six weeks.[7] It may be a complication of acute otitis media.[4] Pain is rarely present.[4] All three types of otitis media may be associated with hearing loss.[2][3] If children with hearing loss due to OME do not learn sign language, it may affect their ability to learn.[8]
A number of measures decrease the risk of otitis media including pneumococcal and influenza vaccination, breastfeeding, and avoiding tobacco smoke.[1] The use of pain medications for AOM is important.[1] This may include paracetamol (acetaminophen), ibuprofen, benzocaine ear drops, or opioids.[1] In AOM, antibiotics may speed recovery but may result in side effects.[12] Antibiotics are often recommended in those with severe disease or under two years old.[11] In those with less severe disease they may only be recommended in those who do not improve after two or three days.[11] The initial antibiotic of choice is typically amoxicillin.[1] In those with frequent infections tympanostomy tubes may decrease recurrence.[1] In children with otitis media with effusion antibiotics may increase resolution of symptoms, but may cause diarrhoea, vomiting and skin rash.[13]
Worldwide AOM affects about 11% of people a year (about 325 to 710 million cases).[14][15] Half the cases involve children less than five years of age and it is more common among males.[4][14] Of those affected about 4.8% or 31 million develop chronic suppurative otitis media.[14] The total number of people with CSOM is estimated at 65–330 million people.[16] Before the age of ten OME affects about 80% of children at some point.[4] Otitis media resulted in 3,200 deaths in 2015 – down from 4,900 deaths in 1990.[6][17]
