Myringosclerosis after tympanostomy tube insertion: Relation with tube retention time and gender

Myringosclerosis is frequent in patients who underwent tympanostomy tube insertion. The frequency of myringosclerosis is much higher in tympanic membranes with tympanostomy tube insertion than tympanic membranes with myringotomy, and the location of sclerotic plaques does not always correspond to the tympanostomy area. The myringosclerosis rate was increased when the tympanostomy tubes stay on tympanic membrane for a long time. Highest myringosclerosis rates were observed if the extrusion time was 12 months or longer. In our analysis, sex and initial age of tube insertion were not significant factors for the development of myringosclerosis after extrusion of tympanostomy tubes.
