Opis:
Introduction: It is estimated that hearing impediment affects approximately 12% of the population. Some forms of hearing disorders can be successfully treated conservatively, while in others surgery plays a key role. Often, therapeutic methods are exhausted and the patient faces the decision about the need for acoustic organ prosthesis. Depending on the causes of anomalies, apparatus for air conduction, bone conduction or cochlear implants are used. A cochlear implant replaces the damaged sensory cells of the inner ear. It constitutes an electronic prosthesis of the acoustic organ, composed of two parts. The internal part (implanted in the inner ear) consists of an implant and electrodes, which conduct electrical signals to the cochlea. The external part consists of a microphone, a speech processor, and a transmitter. Care report: A 70-year-old patient with deep hearing loss in the right ear and deafness of the left ear. During the interview, the patient denied mechanical injuries of the head and neck, acoustic trauma, inflammation or otorrhea. Based on the conducted tests, qualification otolaryngology, audiology, and otoneurology, radiology, surdologopedy and psychology were performed for cochlear implant insertion. The patient was qualified for cochlear implantation in the left ear under general anesthesia. The surgical team was composed of dr hab. Maciej Wiatr, prof. dr hab. Kazimierz Niemczyk, prof. dr hab. Jacek Składzień, MD Agnieszka Wiatr with anesthetic monitoring under the supervision of MD Renata Witkowska. The patient was discharged home on day 7 after surgery in good general and local condition. Simultaneous rehabilitation was started at the Center for Daily Rehabilitation of Hearing and Speech at the Specialist Center of Diagnosis and Rehabilitation for Children and Adolescents with Hearing Disabilities of the Polish Association of the Deaf in Cracow.

Opis:
Background: Patients with vestibular schwannoma (VS) most commonly present with hearing threshold reduction for high frequencies and a falling type of audiometric curve. However, it is doubtful whether all Pure Tone Averages described in the literature characterize patients with VS correctly, as the type of PTA which comprises higher frequencies may be more appropriate for hearing status assessment in those patients. Aim: The aim of this study was to analyze 3 common methods of calculating Pure Tone Averages (PTA1 – 500, 1000, 2000 and 3000 Hz; PTA2 – 500, 1000, 2000 and 4000 Hz; PTA3 – 500, 1000 and 2000 Hz) and to determine which of them is the most reliable for the assessment of VS patients. Material and Methods: The study group included 86 patients operated on due to vestibular schwannoma accessed via the middle cranial fossa. Results: Regarding the method of calculating Pure Tone Averages (PTA1, PTA2 and PTA3) identical or similar correlations were found between the preoperative values of Pure Tone Averages (PTA1, PTA2 and PTA3) and surgery-related hearing loss, as well as individual parameters of audiologic tests. Conclusions: Pure Tone Averages calculated according to 3 different methods (PTA1, PTA2, PTA3) may be used interchangeably in the assessment of hearing in VS patients.

Opis:
Evaluation of acoustic vestibular evoked myogenic potentials (AC-VEMPs) is one of the tests performed to assess the function of the balance system. Evaluation of acoustic ocular vestibular evoked myogenic potentials (AC-oVEMPs) consists in the measurement of potentials evoked within oculomotor muscles, particularly the inferior oblique muscles (the most superficial muscles) with impulses being transmitted along the superior branch of the vestibular nerve from the utricular macula. Despite the fact that the measurement of oVEMPs was introduced relatively recently, it has found widespread use as a diagnostic tool in otology and neurotology. Despite the growing number of literature reports, the methodology of the test and the methods for the interpretation of its results are still subject to debate. This article is dedicated to various aspects of AC-oVEMP tests, including the methodology of the test, interpretation of its results and potential use in the diagnostics of vertigo.

Opis:
Introduction: The treatment and rehabilitation of hypoacusis with the use of cochlear implants is a safe and reliable method suitable for both children and adults. In people affected by chronic otitis media cholesteatomatosa or such who have previously undergone open repair of the ear, we use a special surgical technique known as lateral/subtotal petrosectomy. Material and methods: The study group consisted of patients with profound bilateral sensorineural hearing loss, in which otitis media with and without cholesteatoma has been diagnosed or after open repair of the middle ear. A retrospective analysis of patient data, as well as radiological and audiological results, was conducted. Results: In the Clinic of Otolaryngology and Laryngological Oncology of the Pomeranian Medical University in the years 2008–2018 we performed 90 cochlear implant surgeries, including a petrosectomy in 1 child with cholesteatoma (5 years) and in 2 adults after open repair (62 and 73 years). In all cases the procedure was done in a single stage. Healing proceeded correctly in all patients undergoing petrosectomy. The observation period ranges from 26 to 32 months, computed tomography examinations revealed no indirect characteristics of recurrent cholesteatoma. The patients remain under constant ENT supervision. The child has risk factors for autism and mental retardation, he displays good auditory responses and speech understanding; he has not developed active speech. As regarding free field pure tone audiometry, in adults hearing in the cochlear implant remains at 35 and 40 dB, and speech understanding at 80%. Discussion: Patients with chronic otitis media can be treated efficiently and safely with a cochlear implant using lateral petrosectomy. Lateral/subtotal petrosectomy is the access of choice when deep sensorimotor hearing loss coexists with chronic inflammation in the middle ear.

Opis:
Usher syndrome is the most frequent cause of coexisting sight and hearing disorders genetically determined. Depending on the type of the symptoms, we can single out 3 types of Usher syndrome. Among them the most ad-vanced changes are described in first type. In final stage it leads to deafness and blindness with possible balance dis-orders.This syndome is inherited in autosomal recessive way, but we have to note the occurence of genetical heterogeneity. It causes big diversity of symptoms intensification. Correct diagnosis is important in view of giving genetical advice and eventual diagnostic and terapeutic procedure.

Opis:
Background: Ocular vestibular-evoked myogenic potential (oVEMP) is one of recently introduced tests used to assess the function of the equilibrium system. It is still under research and no consensus has been reached yet. Aim: To analyze AC-oVEMP response parameters in subjects with no history of neurological or vestibular deficits. Material and Methods: The AC-oVEMPs collected from 50 subjects (100 ears) were analyzed in this prospective study for the response presence in the time domain, the latencies and amplitudes of the waves. Results: No statistically significant differences were observed between the right and left ear considering both N1 latency, and amplitude. Significant differences were noted when comparing the groups <40 yo vs ≥40 yo (shorter latencies and higher amplitudes were observed in subjects <40). Conclusions and Significance: This thorough AC-oVEMP analysis in a group of healthy volunteers facilitated the proposal of reference ranges with a simultaneous indication of age-related differences. Shorter oVEMP latencies and higher amplitudes were observed in subjects <40 yo, while in the subjects ≥40 yo the latencies were longer and the amplitudes lower.

Background: The aim was to present the methodology and interpretation of intraoperative hearing monitoring with simultaneous Transtympanic Electrocochleography (TT-ECochG) and direct Cochlear Nerve Action Potential (CNAP) measurements during vestibular schwannoma removal. Materials and Methods: Detailed methodology of measurements and interpretation of results are presented in three exemplary patients who underwent tumor removal via middle fossa approach (MFA) with the use of intraoperative monitoring of hearing with TT-ECochG and direct CNAP performed in real time. In addition, all responses were automatically recorded and stored along with surgical information and subjected to detailed analyses and calculation after surgery. Results: The following changes in TT-ECochG and direct CNAP responses were observed: Patient #1 – TT-ECochG and CNAP responses with minor, but transient, morphology changes (hearing was preserved); Patient #2 – CNAP responses changed significantly but, temporarily, from triphasic into biphasic responses later, with marked but partially reversible desynchronization of CNAP; changes in TT-ECochG responses were also observed but, at the end, returned to baseline (surgery-related deterioration of hearing); Patient #3 – irreversible changes of TT-ECochG and direct CNAP (complete loss of hearing). Conclusions: A combination of TT-ECochG and direct CNAP allows for real-time monitoring of auditory function during vestibular schwannoma resection and surgical manipulation which contribute to the risk of hearing loss. Therefore, the surgeon can be instantly informed about changes which could increase the possibility of preserving the patient’s hearing

Opis:
Ménière’s disease is characterized by sudden episodes of vertigo accompanied by tinnitus and/or feeling of fullness in the ear as well as fluctuating sensorineural hearing loss. Despite numerous studies, the etiology of this disease remains unknown. However, the enlargement of the inner ear’s endolymphatic spaces, referred to as endolymphatic hydrops, is considered the underlying condition. Thanks to recent advances in magnetic resonance (MR) technology, it is now possible to obtain in vivo imaging of endolymphatic hydrops in patients presenting with Ménière’s disease symptoms. Visualization of the inner ear fluid compartments is achieved after gadolinium contrast is administered into the tympanic cavity or via the intravenous route. Evaluation of endolymphatic hydrops is possible as the contrast agent selectively penetrates the perilymph, and endolymph is visualized as contrast defects. The currently used radiological hydrops grading systems include qualitative, semi-quantitative, and volumetric scales. The methods are subject to ongoing modifications to increase their sensitivity and specificity. Numerous studies describe correlations between clinical symptoms and audiological and otoneurological examination results with the endolymphatic hydrops grade. MRI is also applicable in patients’ diagnostics with an incomplete or atypical course of the Ménière’s disease. In the course of the treatment, follow-up MRI scans enable assessing individual treatment modalities’ efficacy in terms of the severity of lesions and the further course of the disease within the inner ear.

Opis:
We present an overview of current diagnostic and therapeutic guidelines on Ménière’s disease. Over the last five years, four studies on this subject have been published. In 2015, five Societies including the Classification Committee of the Barany Society, Japan Society for Equilibrium Research, EAONO - European Academy of Otology and Neurotology, AAO-HNS - American Academy of Otorhinolaryngology - Head Neck Surgery, and Korean Balance Society have issued updated guidelines on the diagnosis and treatment of Ménière’s disease. Other multi-center publications have since been published as well such as the International consensus (ICON) on treatment of Ménière’s disease 2018, European Position Statement on Diagnosis, and Treatment of Meniere’s Disease, Diagnostic and therapeutic strategy in Ménière’s disease, Guidelines of the French Otorhinolaryngology - Head and Neck Surgery Society (SFORL) 2017. The above-listed recommendations include the most recent diagnostic advancements (e.g. inner ear MRI) and new electrophysiological tests, but also discuss other commonly used treatment modalities, result reporting and they take into account the quality of life of the patients following treatment. We present the main clinical challenges in managing Ménière’s disease, principles of diagnosis as well as the treatment introduced at our center. Finally, we discuss fundamental updates contained in the published papers.

Aim: To evaluate acoustically evoked cervical and ocular vestibular miogenic potentials (AC cVEMP and oVEMP) in patients with Susac’s syndrome. We did not seek for a diagnostic replacement test in those patients, but we investigated if the combined application of AC cVEMP and oVEMPs might be helpful as an additional source of information about the disease. Material and methods: To record VEMPs, the EMG standardization method was used to continuously monitor and minimize the variability of the recordings. The stimuli were presented unilaterally one ear at a time. The waveforms were analyzed for the response, latency and amplitude. Susac’s syndrome is a rare disease and two patients were analyzed in this study. Results: In patient #1 stimulation resulted in responses on both sides with latencies within normal and symmetry limits for both c- and oVEMPs; however, the responses presented small amplitudes for cVEMPs. In patient #2, only cVEMPs were present. The P1 latencies were within normal values but amplitudes were low, in addition showing asymmetry between sides, with right side amplitude being smaller. Conclusion: The information provided by the combined application of AC cVEMP and oVEMP might be useful in the diagnostics of Susac’s syndrome revealing additional information about the affected vestibular system and be of help in the treatment and rehabilitation planning.

Objective: The aim of this study is to present a methodology of vestibular evoked myogenic potentials registered from sternocleidomastoid muscle (SCM) using skull tap stimulation (Tap-cVEMP) in a patient with cerebellopontine angle tumor (CPAT). Material and methods: A 23-year-old female with CPAT. The methodology of Tap-cVEMP is introduced. The results of VEMP is confronted with surgical information about the tumor. Results: The results of AC-cVEMP and Tap-cVEMP revealed the inferior vestibular nerve bundle to be affected by the tumor with intact superior bundle. Information obtained from VEMP was confirmed during surgery. Conclusion: Skull Tap Vestibular Evoked Myogenic Potentials (Tap-cVEMP) may be the useful method in the diagnostics of CPAT. AC-cVEMP and Tap-cVEMP may be helpful to evaluate the functional integrity of both vestibular nerve bundles providing the information about their involvement in the pathological process.

Objective: The objective of the study was to present the methodology and interpretation of the results of distortion-product otoacoustic emission phase shift (Shift-DPOAE) measurements in healthy subjects and patients with Meniere’s disease in remission or during the attack. Material and methods: Shift-DPOAE measurements were performed in two healthy subjects with no otological or neurological problems as well as in six patients diagnosed with Meniere’s disease. Results obtained from all eight subjects are presented. Detailed otoscopy, impedance audiometry, pure tone audiometry, DPOAE, and Shift-DPOAE tests were performed in all subjects. Results: Normal results of Shift-DPOAE measurements obtained from two healthy subjects as well as normal (two subjects) and abnormal (four subjects) Shift-DPOAE results obtained from patients with Meniere’s disease are presented in order to thoroughly discuss the methodology and interpretation of Shift-DPOAE measurements. Conclusions: Shift-OAE is a promising diagnostic tool with a great clinical potential for diagnostics and monitoring of Meniere’s disease in patients whose hearing has not yet been damaged. The test is completely non-invasive and can be carried out immediately after the onset of disease attack with symptoms still present at the time of the test; in addition, the procedure takes just several minutes.
Cel: Przedstawienie metodologii badania oraz prezentacja wyników przesunięcia w fazie otoemisji akustycznych produktów zniekształceń nieliniowych ślimaka (Shift-DPOAE), wykonanego u osób zdrowych i z potwierdzoną chorobą Meniere’a w fazie remisji oraz w ostrej fazie choroby w czasie ataku. Materiał i metody: Badanie Shift-DPOAE zostało wykonane u dwóch osób z prawidłowym słuchem i bez żadnych problemów otologicznych i neurologicznych (osoby zdrowe) oraz u sześciu z klinicznie zdiagnozowaną chorobą Meniere’a. W sumie w pracy prezentowano wyniki uzyskane u ośmiu osób. U wszystkich badanych wykonano następujące badania: dokładną otoskopię, audiometrię impedancyjną, audiometrię tonalną, tradycyjne badanie DPOAE oraz Shift-DPOAE. Wyniki: Zaprezentowano i omówiono prawidłowe wyniki Shift-DPOAE uzyskane u dwóch osób zdrowych oraz wyniki prawidłowe (dwie osoby) i nieprawidłowe (cztery osoby) uzyskane u pacjentów z chorobą Meniere’a, w celu dokładnego omówienia metodologii i interpretacji badania Shift-DPOAE. Wnioski: Shift-OAE to obiecujące badanie z dużym potencjałem klinicznym w diagnostyce i monitorowaniu choroby Meniere’a u pacjentów, u których słuch nie został jeszcze uszkodzony. Jest ono całkowicie nieinwazyjne, może być przeprowadzone zaraz po ataku choroby w trakcie trwania objawów, a jego wykonanie zajmuje zaledwie klika minut.
