AbstractObjective:To study the effect of Silastic®sheeting placed in the middle ear during tympanoplasty, including the effect on hearing.Design:Retrospective study.Background:Chronic inflammation of the middle ear is common. Surgical treatment sometimes results in middle-ear adhesions and hearing deterioration.Materials and methods:We selected 106 patients with chronic otitis media, middle-ear adhesions and intact ossicles, based on intra-operative findings. These patients underwent single-stage tympanoplasty either with or without insertion of Silastic sheeting. Audiometry was undertaken pre-operatively and one and 12 months post-operatively.Results:Patients who had undergone Silastic sheet insertion showed significantly better air conduction, bone conduction and air–bone gap averages one year post-operatively, compared with those who had not.

Despite the progress in otosurgery, the efficient treatment of patients with the cochlear form of otosclerosis (according to the classification of N.A. Preobrazhensky, 1962) remains an important task. The authors have developed and implemented an advanced stapedoplasty method, providing the improvement of hearing in this category of patients. and described the methods of differential diagnostics for selection of patients according to the developed method. The article describes in details the early and long-term functional results of surgical treatment of 60 patients with cochlear and mixed II forms of otosclerosis, divided into the main and control groups. The main group is represented by 30 patients who underwent a cartilage-on-vein stapedoplasty according to the improved method. The control group included 30 patients, in which 18 people underwent a cartilage-on-vein stapedoplasty according to the method developed by Lenin Prize winner V. F. Nikitina, and 12 people who underwent V. T. Palchun’s piston stapedoplasty. The results demonstrate a statistically significant improvement of bone conduction in the main group in average by 15–20 dB throughout the entire tone scale (except for high frequencies in some patients) and the complete closure of the bone-air interval with subsequent preservation of the results. Based on the obtained data, the authors present the expediency and perspectivity of implementation of the advanced stapedoplasty method.

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.

Objective: The presence of Carhart’s notch at 2000 Hz in otosclerosis links the changed bone conduction for this frequency with the otosclerotic process occurring in the oval window. The aim of this study is to perform an audiometric assessment of the effectiveness of surgical treatment of otosclerosis depending on the incidence of Carhart’s notch. Methods: The analysis included 116 patients treated surgically for the first time due to otosclerosis. Patients were divided into 4 groups depending on the occurrence of Carhart’s notch, determined by pure-tone audiometry (PTA) before the surgery and 36 months afterward. The mean value of bone conduction thresholds was calculated for 500 Hz, 1000 Hz, 2000 Hz, and 3000 Hz in the groups in which the Cahart’s notch was observed. This value of bone conduction (BC) was a reference point for further analysis in patients who had no preoperative or postoperative Carhart’s notch. Results: The analysis indicated that Cahart’s notch in preoperative PTA is a statistically significant improvement factor for average BC. It was found that over a longer observation period, the presence of Carhart’s notch has adverse effects on the size of the postoperative air-bone gap, and consequently on hearing improvement after surgical treatment. A comparison between patients from the two groups without preoperative Carhart’s notch found that no beneficial effects of the surgery on speech comprehension were observed regarding high-level sensorineural hearing loss (SNHL). Conclusions: (1) In a long-term observation post-stapedotomy, average BC values were found to improve. Nevertheless, the improvement is less evident in patients with preoperative Carhart’s notch. (2) Disappearance of Cahart’s notch after surgical treatment of otosclerosis is a good prognosis of improvement in speech audiometry. (3) Deep SNHL in the absence of Carhart’s notch in PTA constitutes a bad prognostic factor for improvement in speech audiometry in patients qualified for surgical treatment of otosclerosis.
