ABSTRACT
BACKGROUND: Otosclerosis is a cause of 5-9% of all hearing loss. The most effective treatment of otoslerosis is stapedotomy. AIM: The aim of this study was to evaluate the results of otosclerosis surgical treatment and to examine the impact of disease stage, time of the signs, age and sex on the results. MATERIAL AND METHODS: 105 patients who underwent operation due to otosclerosis at the Department of Otolaryngology University Hospital in Zabrze at the age of 18-65 were analyzed. In 25 patients stapedotomy was bilateral. 130 cases of treated ears were included in the statistical analysis. The state of hearing after operation was evaluated with regard to guidance of Hearing and Balance Committee of American Academy of Otolaryngology - Head and Neck Surgery and with consideration of suggestions made by European Academy of Otolaryngology and Neurootology. Mean values of bone and air conduction, air bone gap before, one year after treatment, and at least 4 years after surgery were compared. The influence of stage of the disease in terms of Shambaugh index, lasting of signs, age and sex were evaluated with regard to change of mean hearing loss according to Bell Telephone Laboratories. RESULTS: On the basis of hearing examination evaluating improvement in air and bone conduction and reduction of cochlear reserve, very good and good treatment results were obtained in over 90% of patients in short and long term observations. No influence of disease stage, time of signs lasting, age and sex on the results of treatment - with regard to change in mean hearing loss was shown.

The aim of the study was to describe the value of High Resolution Computed Tomography (HRCT) with MPR and VR reconstruction of the temporal bone in patients with persistent vertigo after stapedotomy. High Resolution Computed Tomography with MPR and VR reconstruction of the temporal bone in the axial and coronal planes with 0.625 - mm slice thickness were performed in 2 patients with persistent vertigo after stapedotomy. Persistent vertigo were observed in 2 patients suffered from otosclerosis several months after stapedotomy. High Resolution Computed Tomography with MPR and VR reconstruction of the temporal bone showed in both cases too long stapes prosthesis. On the base of HRCT results restapedotomy and length reduction of stapes prosthesis were done. The vertigo was resolved in all the cases with revision surgery. HRCT with MPR and VR reconstruction can diagnosed the possible cause of persistent vertigo in patients after stapedotomy.
