The aim of examination was value of exploratory anterior tympanotomy in differentiation causes of conductives hearing loss and assessment of results treatment. Materials of examinations determined 34 patients aged 15-66 years, treated in 1995-2000 years, who qualified to exploratory anterior tympanotomy in aim decision of cause of conductives hearing loss. Among of examined were 14 patients with suspicion of otosclerosis (41.2%), 12 patients with unclear etiology of hypoacusis (35.3) and 8 patients with deterioration of hearing after stapedectomy (23.5%). Preoperative diagnostic embraced: a history, otolaryngologic examination, full audiologic examination and chosen cases of radiologic assessment of temporal bone by computer tomography. After perioperative decision cause of conductive hypoacousis were performed of operations of improved hearing and comprised of average hearing loss by CPT and PTA pre- and postoperative treatment. After performed of exploratory tympanotomy there vere stated following causes of conductive hypoacusis: otosclerosis (61.8%), separated of prosthesis after stapedectomy (14.7%) synechia of prosthesis with tympanic membrane (8.8%) and in singles causes of ossicular synechia in tympanic cavum (5.9%), tympanosclerosis (5.9%) and vitium of middle ear (2.9%). The best of hearing improvement after repairment operations of conductive system were obtained in cases of stapedectomy, exchange of prosthesis after stapedectomy, reconstruction of system by TORP prosthesis, however smaller improvement after operations of synechias of stapes prosthesis with surroundings and postoperation of tympanosclerosis.
