Classification of Barros Luco Hospital’s tympanic pockets retraction

Abstract

Introduction: Pockets of posterior-superior retraction of the pars tensa (BR) can progress with ossicular erosion and cholesteatoma. Has been described a series of pa- thophysiological mechanisms that explain the higher occurrence of retraction in this area.In the Barros Luco Hospital we use a classification, a modification of Sadé, that would represent best the progression of the disease together to a treatment proposed. Aim: Applying our classification of BR and describe clinical and audiologically each grade with the indicated treatments. Classify and describe each grade by: PTP bone and air, first surgery, disease progression, otorrhea, hearing loss, ossicular erosion and OME Material and method: Retrospective and descriptive analysis of 83 patients and 92 earssubmitted to the Department of Ear of Otolaryngology Service’s Hospital Barros Luco, plus review of the clinical record and the first surgical protocol between the years 2005 to 2009. Minimum follow-up of 12 months. Variables: age, sex, and air bone PTP in 4 frequencies, first surgical procedure, disease progression, otorrhea, hearing loss, ossicular erosion and OME. Conclusion: This classification would reflect degrees of severity of BR in aspects such as otorrhea, ossicular erosion and proposed treatment. The presence of hearing loss and air PTP does not reflect the degree of disease progression. An amendment to our classification is proposed.
