METHOD FOR PREDICTION OF DEGREE OF HEARING LOSS IN OTOSURGERY IN CHRONIC OTITIS MEDIA

摘要

FIELD: medicine.SUBSTANCE: following criteria are assigned with points: inflammatory process time of a first diagnosis of chronic otitis media; age of the diagnosis of chronic otitis media; degree of an auditory tube patency; degree of an auditory tube patency by tympanometry; perforation location and size; degree of ear bone and bone structure destruction; degree of tympanic mucosa thickening as a presentation of manifestation of a smoldering catarrhal inflammation - mucositis; degree of tympanic mobility in relation to the projection of annulus tympanicus; air-conduction threshold within the speech frequencies by tonal audiometry; air-bone gap within the speech frequencies by tonal audiometry; type of hearing loss by tonal and computed autiometry; degree of bacterial contamination of the tympanum and antrum; type of a tympanic discharge agent; type of micromycetes in the discharge from the tympanum and antrum; X-ray findings of a pyramid; observed symptoms of a nasal, nasopharyngeal, paranasal sinus pathologies; observed symptoms of an allergic pathology in the patient; type and extent of the previous reconstructive sanitation surgery; type and extent of the prospective reconstructive sanitation otosurgery. The derived points are summed up to state either a favourable or unfavourable prognosis of the otosurgical hearing outcome.EFFECT: method provides the objective and integrated estimate of degree of hearing loss manifestation and prediction of developing hearing loss in chronic otitis media after the reconstructive sanitation otosurgery.3 ex
