Oncocytoma is a rare, benign salivary gland tumour with slowly course. It usually occurs in the parotid gland, seldom in submandibular gland. This report presents a case of parapharyngeal oncocytoma of the left parotid gland in 77-yearold patient, treated in 2nd ENT Department of Medical University of Silesia in Zabrze. On the basis of physical examination and preoperative radiologic studies (computed tomography scan of nasopharynx, magnetic resonance imaging, Doppler ultrasonography of carotid and vertebral arteries) the extensiveness of the tumour was determined and the surgical procedure was undertaken. The removal of a whole tumour was performed through a cervical – transpharyngeal approach with midline mandibulotomy. A follow-up of 30 months hasn’t revealed any recurrence of the oncocytoma.

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.

Wstęp: Otoskleroza jest przyczyną od 5 do 9 % wszystkich niedosłuchów. Najczęściej wykonywanym zabiegiem operacyjnym w otosklerozie jest stapedektomia Cel pracy: Celem pracy była ocena wyników leczenia operacyjnego chorych na otosklerozę oraz zbadanie wpływu stopnia zaawansowania choroby, czasu trwania dolegliwości, wieku oraz płci na uzyskiwane wyniki. Materiał i metody: Badaniu poddano 105 chorych w wieku 18–65 lat operowanych z powodu otosklerozy w Katedrze i Oddziale Klinicznym Laryngologii w Zabrzu w latach 2000–2010. U 25 pacjentów zabieg wykonano obustronnie. Analizie poddano wyniki uzyskane po 130 zabiegach na strzemiączku. Stan słuchu chorych po operacji oceniono zgodnie z zaleceniami Komitetu do Spraw Słuchu i Równowagi Amerykańskiej Akademii Otolaryngologii, Chirurgii Głowy i Szyi, uwzględniając sugestie Europejskiej Akademii Otologii i Neurootologii. Porównywano średnie wartości przewodnictwa kostnego i powietrznego, średnie wartości rezerwy ślimakowej przed, rok po leczeniu (obserwacja wczesna) oraz minimum 4 lata po stapedotomii (obserwacja późna). Oceniono także zmianę Wskaźnika Procentowej Poprawy Słuchu (WPPS). Zbadano wpływ stopnia zaawansowania choroby (według wskaźnika Shambaugha), długość trwania dolegliwości przed zabiegiem, jak również wpływ wieku oraz płci na wyniki leczenia, które oceniano według zmiany średniego ubytku słuchu zgodnie z Bell Telephone Laboratories. Wyniki: Wyniki badań słuchu – oceniające poprawę przewodnictwa powietrznego i kostnego, zmniejszenia rezerwy ślimakowej i WPPS – przyniosły bardzo dobre i dobre wyniki u ponad 90% chorych w obserwacji tak wczesnej, jak i późnej. Wykazano brak wpływu stopnia zaawansowania choroby, długości trwania dolegliwości, wieku oraz płci chorych na wyniki leczenia operacyjnego otosklerozy ocenione zmianą średniego ubytku słuchu.

Introduction. The amplitude of click evoked otoacoustic emissions can be suppressed (reduced) with contralateral acoustic stimulation (CAS). This is thought to be due to the inhibitory control that the medial efferent auditory nerve exerts on outer hair cell function. One commonly used test of medial olivocochlear (MOC) function in humans involves measuring the degree of suppression of ipsilateral otoacoustic emissions (OAEs) by CAS. This effect is called contralateral suppression, efferent effect or olivocochlear refl ex. Aim of the study. The objective of this study was to measure cut-off level of contralateral suppression, sensitivity and specifi city of the efferent test. Material and methods. To evaluate the function of MOC system click evoked otoacoustic emissions (CEOAEs) with and without continuous contralateral broadband noise (BBN) stimulation were recorded in 14 patients with multiple sclerosis, 16 patients with unilateral cerebello-pontine angle tumor and control group matched for age and gender. BBN was presented at 50 dB SL and otoacoustic emissions were recorded in response to nonlinear clicks at 70 +/- 3 dB SPL. Results. The cut-off level was established at -1.4 dB. For 1.4 dB cut-off level of contralateral suppression the sensitivity of the efferent test was 90% and specifi city was 70%. Conclusions. To conclude, assessment of efferent suppression may be a useful addition to the battery test employed in the investigation of multiple sclerosis and cerebello-pontine angle tumors. The MOC suppression test may provide a tool for an early diagnosis of the brainstem pathology.
