Cholesteatoma (ker- less- tea- a- toe- ma) is a progressive destructive ear disease. Most cases occur in children and young adults, but it can affect any age. Skin builds up in layers and erodes the bone of the middle ear and mastoid. In its early stages, cholesteatoma tends to attack the ossicles, the small bones conducting sound from the eardrum to the inner ear. This causes partial deafness, sometimes with unpleasant smelling discharge and pain. If the disease progresses, it can erode the inner ear causing total and permanent deafness and tinnitus. The inner ear also contains the balance organ.
Biofilms form when bacteria adhere to surfaces in aqueous environments and begin to excrete a slimy, glue-like substance that can anchor them to all kinds of material. I recently saw Jacob, a 3 year-old, who has had recurrent acute otitis media. His tympanograms were Type B in both ears, with admittance of.15 mmho, width of 300. Fluid in the ear, also called serous otitis media (SOM) or otitis media with effusion (OME), is usually the result of an ear infection, but it can occur under any.
If cholesteatoma erodes into the balance organ, vertigo, a severe form of dizziness, results. Cholesteatoma can also attack the facial nerve causing facial paralysis. In rare cases the disease erodes upwards. The roof of the ear is the floor of the brain. If this thin plate of bone is breached, meningitis, brain abscess and death can result. The cholesteatoma is made of layers of dead skin, like an onion. Only the outer layer, known as the matrix, contains live growing skin cells.
Cholesteatoma is the most serious form of chronic ear infection. It is not a tumour, though it can behave like one. It is not cancer and never spreads widely throughout the body – though it can cause quite enough trouble by its local destructive effects. In most cases, the progress of cholesteatoma is slow. It can take years or even decades to eat its way slowly through the structures of the ear.
Rapidly progressive disease, over a time course of a few months and sometimes weeks, is commoner in children and in the presence of active acute infection. The outer and middle ear work like an old mechanical gramophone in reverse. They collect sound energy, and concentrate it onto the small area of the stapes footplate. The normal ear and hearing.
Tinnitus is the hearing of sound when no external sound is present. While often described as a ringing, it may also sound like a clicking, hiss or roaring. Rarely.

The human ear is divided into three parts: outer earmiddle earinner ear. Outer ear. The outer ear consists of the pinna and the ear canal. The outer ear funnels sound waves in air to the eardrum. Eardrum (tympanic membrane)Normal left eardrum (tympanic membrane)The eardrum is a paper- thin membrane, shaped like a miniature satellite dish, 8- 1.
The tympanic membrane forms the boundary between outer and middle ear. Middle ear. The eardrum vibrates when sounds arrive through the external ear canal. The vibrations are transmitted to the inner ear via three small bones (ossicles) suspended in the middle ear.
Ossicles. Abnormally thin right eardrum damaged by glue ear and showing ossicles – malleus incus and stapes. The three little bones (oss- i- culls) aremalleus (mal- ee- us) shaped like a hammerincus (ink- us) shaped like an anvilstapes (stay- peas) shaped like a stirrup.
Their job is to concentrate the sound energy, collected by the relatively large area of the eardrum, onto the tiny footplate of the stapes. The outer and middle ear work like an old mechanical gramophone in reverse. The gramophone needle picks up vibrations from the grooves in the record, passes them to a vibrating membrane, then into the large horn, and so to the outside world.
The outer and middle ear collect sound from the outside world and concentrate it down to the stapes footplate. The footplate moves like a piston in the oval window, the opening of the inner ear. Inner ear. The inner ear has two parts, the cochlea and the vestibular labyrinth.
Cochlea. The cochlea is the hearing part of the inner ear. It is a biological microphone. Sound vibrations are turned into electrical signals and sent to the brain in the nerve of hearing. Vestibular labyrinth. The vestibular labyrinth of the inner ear is concerned with balance. Disturbance of the balance organ of the inner ear can cause vertigo.
Eustachian tube. The Eustachian tube connects the middle ear with the back of the nose. To hear normally, the eardrum and ossicles must be able to move easily. For this to occur, the middle ear must contain air at the same atmospheric pressure as the outer ear. Air in the middle ear comes from the back of the nose, via the Eustachian tube.
The job of the Eustachian tube is to ventilate the middle ear, keeping the pressure in the middle ear the same as in the outer ear. Most middle ear diseases, including cholesteatoma, are associated with poor Eustachian tube function.

Principal author(s)Nicole Le Saux, Joan L Robinson; Canadian Paediatric Society, Infectious Diseases and Immunization Committee. Paediatr Child Health 2. Abstract. Acute otitis media (AOM) continues to be a common infection in young children. Milder disease, usually due to viruses or less virulent bacteria, resolves equally quickly with or without antibiotics. A bulging tympanic membrane, especially if yellow or hemorrhagic, has a high sensitivity for AOM that is likely to be bacterial in origin and is a major diagnostic criterion for AOM.
Perforation of the tympanic membrane with purulent discharge similarly indicates a bacterial cause. Immediate antibiotic treatment is recommended for children who are highly febrile (≥3.
C), moderately to severely systemically ill or who have very severe otalgia, or have already been significantly ill for 4. For all other cases, parents can be provided with a prescription for antibiotics to fill if the child does not improve in 4. Amoxicillin remains the clear drug of choice. Ten days of therapy is appropriate for children < 2 years of age, whereas older children can be treated for five days. Key Words: AOM; MEE; OME; PCV1. TMThe present position statement updates a previous CPS document released in 2. Based on published evidence, this revision is intended to be a guide for sound clinical decision making.
The recommendations are not intended for treating children < 6 months of age or for those with craniofacial abnormalities, immunocompromising conditions, tympanostomy tubes or recurrent acute otitis media (AOM). The pathogenesis of AOMAOM is extremely common, and 7.
Normally, mucocilliary clearance mechanisms in the eustachian tube (ET) ventilate and drain fluid away from the middle ear. ET dysfunction or obstruction due to a viral infection or other causes of mucosal inflammation can impair this normal mechanism. The lack of middle ear drainage leads to fluid stasis and, if the fluid is colonized with bacterial and/or viral pathogens, can lead to AOM. Children are predisposed to AOM because they acquire viral infections more often than adults, and their ETs are also shorter and more horizontal compared with adults.Risk factors for AOM include young age and frequent contact with other children, which increases exposure to viral illnesses. Other risk factors include orofacial abnormalities (such as cleft palate), household crowding, exposure to cigarette smoke, pacifier use, shorter duration of breastfeeding, prolonged bottle- feeding while lying down and a family history of otitis media. Children of First Nations or Inuit ethnicity are also at higher risk for AOM. A small proportion of children have lower levels of secretory immunoglobulin A or persistent biofilms in the middle ear, which may play a role in increasing the risk for recurrent AOM.- There is a clinical spectrum of middle ear infections associated with the initiation and progression of infection leading to bacterial AOM.
Middle ear fluid from AOM cases often harbour both viruses and bacteria; however, children who experience spontaneous resolution of AOM are likely to have viral infections alone or to have bacterial organisms that are less virulent (eg, Moraxella catarrhalis and some strains of Haemophilus influenzae) compared with Streptococcus pneumoniae and Streptococcus pyogenes (group A streptococci [GAS]).[1. In one prospective study, 2. AOM during the first week of an upper respiratory infection, while a further 7% had myringitis without effusion.[1. Thus, the clinical presentation of AOM can vary with the stage of illness (early versus later). Also, children may or may not progress to overt bacterial AOM depending on which viruses or bacteria are present in the nasopharynx.[1. Bacteria commonly associated with AOMThe most common bacteria causing AOM are S pneumoniae, H influenzae, M catarrhalis and (less commonly) GAS. Usually there is a single bacterial pathogen but coinfection can occur.
Studies following the routine use of the seven- valent conjugated pneumococcal vaccine (PCV7) demonstrated the increasing importance of nonvaccine type S pneumoniae and non- typable H influenzae.[1. However, more recent studies performed during the 1.
S pneumoniae overall.[1. It is not yet known whether the absolute number or only the percentage of cases of AOM due to H influenzae and M catarrhalis will increase with the widespread use of the 1. PCV1. 3). It has been estimated that the routine use of PCV7 in Canada has decreased the incidence of AOM by 1. S pneumoniae in children has been significantly reduced.[1.
