    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:
    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.

    Opis:
    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.

    Opis:
    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.

    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.

    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.

    qualification to cochlear implant
    Opis:
    Over thirty years of progress in development of surgical techniques and cochlear implant technology led to a change in approach and extending of indications for qualifying patients to treatment of sensorineural hearing loss. Basic indications for cochlear implants include bilateral deafness, bilateral residual hearing or profound bilat-eral sensorineural hearing impairment as well as lack of acoustic gain from classic air conduction hearing aids af-ter a minimum of 5-6 months of use. Methods of subjective and objective hearing assessment are applied. Psycho-logical evaluation is aimed at assessing expectations of the patient/child’s parents, motivation, and intellect with regard to the presence of deficits that might pose difficulty in the course of further rehabilitation as well as accep-tance of this new type of stimulation. Speech and language evaluation takes into consideration the current level of speech development, articulation disorders related to hearing impairment, and the way to communicate with the environment. Final qualification requires imaging diagnostics of the head/ears (CT and/or MRI). Our surgi-cal experience allowed for implanting children with various congenital anomalies of the inner ear. Inflammation within the tympanic cavity and air-filled spaces of the mastoid process might require removal of inflammatory foci prior to surgery or selection of different surgical approach.

    qualification for bilateral implants
    Opis:
    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.

    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.
