Czynniki prognostyczne u chorych leczonych operacyjnie z powodu perforacji błony bębenkowej przy nieuszkodzonym łańcuchu kosteczek słuchowych

Background: Ear drum perforation is a typical feature in chronic otitis media. It can have posttraumatic etiology or it is observed in acute otitis media too. Aim: This paper is intended to evaluate effectiveness of tympanic membrane reconstruction and indicate factors which have an influence on hearing im-provement after myringoplasty. Material and methods: Analysis involves ca. 500 individuals operated on ear in Department of Otolaryngology at the Jagiellonian University between 2004 and 2009. Results: 120 individuals were operated on for the first time due to chronic otitis media with intact ossicular chain. Statistically significant heating im-provement was observed in patients with discharge, without discharge and in group with scars. Conclusions: The presence of granulation changes is an unfavorable prognostic condition in the patients with ear drum perforation. In clinical practice, the criterion which often determines the application of either of the materials in myringoplasty are operator's preferences, as well as the availability of given material for transplanting.
