In fact, some medical researchers consider myringosclerosis and tympanosclerosis autoimmune diseases. Retrospective Case Series. The formation of granulation tissue in the middle ear space begins with a break in the basement membrane of surface epithelial cells (figure I). 12-24), reactive foreign body–type giant cells containing lipid crystals—cholesterol granuloma 174 (Fig. 12-25), fibrous adhesions and scarring and calcification of the eardrum (tympanosclerosis 175), and bone resorption 176 destroy the auditory function of the middle ear. The presence of granulation tissue, especially when it is abundant, may be a factor that contributes to treatment failure of acute infections, and the evolution of AOM into CSOM. This mechanism differs from the normal healing process of skin wounds where the squamous epithelium migrates over a newly formed granulation tissue layer.

To establish comprehensive transcriptomic profiles of cholesteatoma perimatrix tissue and granulation tissue from chronic otitis media (COM) that did not develop cholesteatoma, which can indicate molecular pathways involved in the cholesteatoma perimatrix pathology and invasiveness. Perimatrix of middle ear cholesteatoma: A granulation tissue with a specific transcriptomic signature. Granulation tissue proliferates, an enzyme production is initiated and phagocytes help to eliminate or to organize the middle ear content. Causes . migrated to the outside of the drum. Scott C. Manning, MO AttheSeattle Children' sHospital,once 0 1'twice ayear we find that what appears to be granulatio n tissue is actuaIly a rhabdomyosarcoma of the temporai bone. On the basis of these findings some practical considerations can be made on tympanoplasties in human.
It can develop quickly in a draining ear, and is already present in many infections of less than 6 weeks’ duration. In that case, it is probably prudent to remove the granulation tissue and the tube in one procedure. The clinical picture corresponds to otitis media adhaesiva.

In myringosclerosis and tympanosclerosis, the calcium deposits are thought to form when the body's normal healing response goes awry.

While scar tissue can have a similar appearance to these conditions, it is not the same.

The closure of the connective tissue defect has always a tendency to lay behind the healing of the epithelial layer.
