symptoms of otitis media (OM) are: | draining of pus from the ear (otopyorrhea); more severely, infection of the mastoid process (mastoiditis); inflammation of the brain tissue near the middle ear (otoencephalitis). |
recurrent episodes of otitis media may cause: | scarring of tympanic membrane, leading to hearing loss. |
treatment of otitis media (OM) | bed rest, antibiotics, analgesics(pain relievers) |
The usual treatment for children with recurrent infection is ther use of: | Pressure-equalizing tubes (PE tubes) |
disorder characterized by an abnormal hardening (ankylosis) of bones of the middle ear (ossicles)that causes hearing loss | otosclerosis |

otosclerosis causes: | the formation of a spnogy growth at the footplate of the stapes decreasing its ability to mobe the oval window |
ringing sound: | tinnitus |

development of otosclerosis is typically closely tied with: | genetic factors (if one or both parents have the disorder, the child is at high risk for developing the disease) |
corrective surgery for otosclerosis involves: | surgical removal of part of the stapes (stapedectomy, stapedotomy)and implanting a prosthetic device |
