Subjects. 11 adults cochlear implant users, age since 18 till 70 years old (mean 43); 6 male and 5 female; diagnosis-postlingual deafness; used CI over 3 years. Method. The aim of study was evaluation of an optimal number of spectral speech coding maxima. The speech audiometry in free fi eld for programmed 8, 10 and 12 spectral maxima and subjective evaluation of quality of speech perception in different acoustic environmental were performed. Results. Results of the study showed the better speech intelligibility for programmed 8 (approx. 54%) and 10 spectral maxima (27%). Conclusion. The number of speech spectral maxima over 10 is not necessary to increasing of speech intelligibility. In the BTE (behind the ear) speech processor the power consumtion were important reduced for 8 spectral maxima. Application of 810 number of maxima is optimal in fi rst session (switch-on) programming of speech processor.

In recent years, the number of children with bilateral implants has been growing. Bilateral implantation, by im-proving hearing, has beneficial influence on auditory-verbal therapy results. Children with bilateral implants have a chance for acquiring communication skills typical for a given linguistic system and society they live in, at the level similar to natural acquisition. There is an ongoing discussion as to how the therapy of bilaterally-implanted children should be conducted. This article proposes a therapeutic approach based on the current literature and practical expe-rience of the author.

Introduction: Profound hearing loss significantly affects the quality of life of deaf people as well as their families. Observation of the benefit from the use of cochlear implants in deaf patients allows to assess the success of treatment with this method and its impact on the quality of life of these patients. The aim of this study was to determine the quality of life in patient after the cochlear implantation in the material of Department of Phoniatrics and Audiology of the Medical University in Poznań. Material and methods: The study involved implanted patients who voluntarily joined to the project entitled "Observational study of the implanted patient (Cochlear-IROS)". It has a prospective character, it is an international and long-term study, covering the observation of patients up to three years after implantation. Standardized HUI and SSQ questionnaires were used. 70 patients were included in the analysis, the mean age at the time of the cochlear implantation was 47.6 years. In the research group there were 33 men and 37 women. In the whole group, the patients' age at implantation was at least 18 years, max. 80 years. Results: The results of the SSQ questionnaire, which deals with the self-assessment of hearing ability in everyday situations, indicate that in the subjective assessment of patients one year after surgery the speech hearing improved by 77%, spatial hearing by 84%, and the quality of hearing by 49%. The general quality of life before the first connection of the sound processor according to the HUI questionnaire, the patients rated at 0.49 (0-1 scale, where 0 - corresponds to the death condition and 1 - full health). After one year from the implantation, this rating increased to 0.56. Conclusions: The implantation of the cochlear implant significantly increases the patient's quality of life, its physical and emotional functioning. Statistically significant better self-assessment of patients mainly concerned hearing speech and spatial hearing - especially after 1 year of connecting the speech processor.

Introduction: Some patients with profound sensorineural hearing loss have inner ear malformations. Initially, those were believed to be a contradiction to cochlear implantation. However, with the advance of cochlear implant surgery and technology, it has become possible to treat this group of patients. However, cochlear implantation in the case of inner ear malformations can be associated with numerous surgical difficulties and possible complications. Purpose: The paper aims to present: (1) modern classification of inner ear malformations, (2) surgical and clinical challenges related to all types of malformations, and (3) cases of inner ear malformations identified in the authors’ centers. Material and methods: Of 111 children enrolled for cochlear implantation in three clinical centers, a group of patients with malformations of the inner ear was selected. We analyzed: preoperative imaging studies of patients performed prior to cochlear implantation, hearing tests, surgical protocols of cochlear implantation, results of intraoperative measurements and intraoperative imaging studies. We discuss what is currently believed to be the leading classification of inner ear malformations. Results: In 19/111 (17%) children, we diagnosed severe inner ear malformations in 35 ears. In 13/19 (68%) patients the malfor mations were bilateral and symmetrical, while 6/19 (32%) patients had different malformations in the right and left ear or one-sided malformation. All inner ear malformations described in the classification were found, except for rudimentary oto cyst. The most common are: cochlear hypoplasia, incomplete partition, and enlarged vestibular aqueduct. Discussion: Severe inner ear malformations are a major diagnostic and clinical challenge in children qualified for cochlear implantation. They can preclude or considerably complicate cochlear implantation and postoperative care. Inner ear malformations are found in imaging studies even in 20 to 30% of patients with profound hearing loss.

Introduction: Although it is recommended to perform cochlear implantation in both ears at the same time for management of profound hearing loss in children, many centers prefer to perform sequential implantation. There are many reasons as to why a simultaneous bilateral implantation is not commonly accepted and performed. The major risk is the possibility of bilateral vestibular organ impairment. However, it is beyond doubt that children who received the first implant should be given a chance for binaural hearing and associated benefits. In the literature, there are no homogenous criteria for bilateral implantation, and it is hard to find uniform and convincing algorithms for second cochlear implantation. The aim of this study is an attempt to identify a safe way of qualifying for second cochlear implantation in children. Material and methods: Forty children with one cochlear implant were qualified for the second implantation. During qualification, the following were taken into account: time of the first implantation, audiometry results, use of the hearing aid in the ear without an implant and benefit of the device, speech and hearing development, and vestibular organ function. R esults: Fifteen out of forty children (38%) were qualified for the second implantation. In 35% of children, the decision was delayed with possible second implantation in the future. Eleven children (27%) were disqualified from the second surgery. Discussion: During evaluation according to the protocol presented in our study, 38% of children with a single cochlear implant were qualified for the second implantation with a chance for an optimal development and effective use of the second cochlear implant. We are convinced that sequential implantation with a short interval between surgeries and with an examination of the vestibular organ, hearing and speech development as well as an assessment of potential benefits from the second implant (bimodal stimulation) before the second implantation is the safest and most beneficial solution for children with severe hearing loss.

Aim: The study aimed to assess the auditory skills in multi-handicapped children with cochlear implants. Material and methods: The study assessed 34 children, who were implanted due to the bilateral profound sensorineural hearing loss. Apart from the hearing loss, all of the subjects suffered from additional impairments (mild motor disabilities, cerebral palsy, cognitive disability, specifi c learning disability, behavioral disorders, sight impairment), 29 (85.29%) from more than one. Cochlear implantation took place in the Department of Otolaryngology at the Medical University of Warsaw in Poland. The age at implantation ranged from 1.3 to 7.5 years old (mean 3.2 years, SD 1.64). The retrospective review of medical charts, audiology and speech pathology records was based on Champions profi le with evaluation at 6, 12, 18-24 months, and 3 years after implantation. When a patient had been referred for developmental evaluation by psychologist, this source of information was also used. Results: All of the subjects suffered from additional impairments, and most of them presented more than one additional disability. Individually and as a group, these patients respond well to cochlear implantation. The study population showed improvement in communication code in 31 patients (91.18%), and no improvement in 3 patients (two of them had 6 months follow up and one 12 months follow-up). Also progress in auditory skills was noted in the study population, which was measured as the awareness in environmental sounds – Categories of Auditory Performance (CAP). Conclusions: Multi-handicapped children receive benefi t from cochlear implantation. The rate of this improvement is slow but offers better quality of life due to better auditory-communication skills, better self-independence and social integration. The results of implantation in presented group of patients is encouraging.

Introduction: Preoperative imaging, besides audiological evaluation, plays a major role in evaluation of candidacy for auditory implants, and in particular cochlear implants. It is essential to assess whether the basic criteria necessary for implantation are met. Diagnostic imaging is crucial not only in determining candidacy, but also determining the feasibility of cochlear implantation as it allow to anticipate surgical difficulties which could preclude or complicate the implantation of the device. The aim of the study is to present the protocol for the evaluation of preoperative imaging studies with particular focus on the factors potentially affecting clinical decisions in children qualified for cochlear implantation. Material and method: Preoperative imaging studies of 111 children performed prior to cochlear implantation were analyzed: high-resolution computed tomography (HRCT) of temporal bones and MRI. The assessment was made according to the presented protocol. Results: Pathologies and anomalies identified during the assessment of preoperative imaging studies significantly altered clinical decisions in 30% of patients. In the study group, in 17% of patients inner ear malformations were identified. 2.7% of children were disqualified from a cochlear implantation due to severe congenital inner ear malformations. 9% of the patients have had bacterial meningitis. In 50% of them difficulties related to complete or progressive cochlear ossification occurred. In 4.5% of patients less common surgical approaches other than mastoidectomy with a posterior tympanotomy were applied. Discussion: Preoperative imaging allow for the identification of significant pathologies and anomalies affecting qualification decisions and further treatment. HRCT and MRI are complementary to each other for preoperative imaging. The two modalities in combination allow accurate and optimal evaluation of the anatomical structures prior to implantation. Inner ear malformations and cochlear ossification following meningitis are relatively frequently encountered in children qualified for a cochlear implant.

Objectives: The aim was to evaluate the position of the cochlear implant electrode inside the cochlea and damage to cochlear structures associated with the implantation itself using cone beam computed tomography technique (CBCT). Material and methods: Nine human cadaver temporal bones were used, five were implanted with round window approach and in other four anterior cochleostomy was used for insertion. After implantation the temporal boneswere scanned with CBCT scanner and the images were then analyzed. The degree of insertion damage was evaluated in two-tier scale, where the first degree included damage to basilar membrane, and the second degree covered damage associated with pushing up into the scala vestibuli. Results: The first degree of cochlear damage was noted in three temporal bones implanted with the round window approach and in two with cochleostomy, and the second degree of damage was noted in two and one temporal bones respectively. The analysis did not show any correlations between depth of insertion and degree and extend of damage in both analyzed groups, also no significant differences were found between the two groups. Conclusions: The good quality of the images presents CBCT as a good method for the evaluation of the cochlear implant electrode position in the inner ear structures. CBCT holds the promise for intraoperative imagining during cochlear implantation.

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.

INTRODUCTION There so far have been no psychological studies on stress coping strategies used by prelingually deaf individuals. Assessment of the efficacy of coping in confrontation with stress is of key importance in the case of persons with a handicap, such as prelingual deafness, and enables one to propose them an adequate offer of hearing and speech (re)habilitation, including psychological intervention. The aim of this study was to compare prelingually deaf adult cochlear implant (CI) users with hearing individuals in terms of stress coping strategies taking account of CI experience, the use of sign language and socio-demographic variables. MATERIAL AND METHODS Study was conducted by post and involved 79 persons with prelingual deafness aged 19–62 years, using CIs implanted after 18 years of age, for whom the response ratio was 63.3%, and hearing persons. An inquiry form and Brief COPE questionnaire were used. RESULTS Prelingually deaf CI users more seldom than hearing persons use active coping, also they less often use psychoactive substances, while they more often use behavioral disengagement. Sex, age, marital (partnership) status and work significantly influence the coping strategies used. Longer CI experience is related to using self-blame and turning to religion more seldom. Individuals who use sign language significantly less often use venting as a stress coping strategy. CONCLUSIONS Stress coping strategies used by prelingually deaf CI users differ significantly from those used by hearing persons as well as postlingually deaf CI users. It is therefore not expedient to treat CI users as a homogenous group irrespective of the deafness etiology, particularly in planning rehabilitation management and in research.

W S T Ę P Strategie radzenia sobie ze stresem u osób z głuchotą prelingwalną nie były, jak dotąd, przedmiotem badań psychologicznych. Ocena skuteczności radzenia sobie w konfrontacji ze stresem nie tylko odgrywa ważną rolę w przypadku osób z niepełnosprawnością, jaką jest głuchota prelingwalna, ale także pozwala zaproponować adekwatną ofertę w zakresie rehabilitacji słuchu i mowy, w tym interwencji psychologicznej. Celem badań jest porównanie osób dorosłych prelingwalnie ogłuchłych z implantem ślimakowym (cochlear implant – CI) z osobami słyszącymi w zakresie strategii radzenia sobie ze stresem (coping), z uwzględnieniem czasu korzystania z CI, znajomości języka migowego oraz zmiennych socjodemograficznych. M A T E R I A Ł I M E T O D Y Badania przeprowadzono drogą pocztową, objęto nimi 79 osób z głuchotą prelingwalną w wieku 19–62 lat z CI wszczepionym po 18 r.ż. oraz osoby słyszące. Wskaźnik odpowiedzi zwrotnych wynosi 63,3%. Wykorzystano ankietę informacyjną i kwestionariusz Mini COPE. WYNIKI Osoby z głuchotą prelingwalną z CI stosują aktywne radzenie sobie ze stresem rzadziej niż osoby słyszące, rzadziej także sięgają po substancje psychoaktywne, częściej natomiast zaprzestają działań. Płeć, wiek, status małżeński (partnerski) oraz praca (nauka) odgrywają istotną rolę w obszarze wykorzystywanych strategii coping. Dłuższy czas korzystania z CI wiąże się z rzadszym obwinianiem siebie i zwracaniem się ku religii. Znajomość języka migowego sprzyja istotnie rzadszemu posługiwaniu się strategią wyładowania w konfrontacji ze stresem. WNIOSKI Strategie radzenia sobie ze stresem, jakimi posługują się osoby prelingwalnie ogłuchłe z CI, znacząco odróżniają je od osób słyszących, ale także i od postlingwalnie ogłuchłych z CI. Nie jest zatem wskazane traktowanie osób z CI jako jednorodnej grupy z pominięciem etiologii głuchoty, zarówno w planowaniu działań rehabilitacyjnych, jak i badawczych.
