The Impact

Hearing improvement represents one of the may valuable outcomes in microtia and aural atresia reconstruction surgery. Most patients with poor development in their hearing function have had a severe microtia. Conventional methods to improve hearing function are bone conduction and bone anchored hearing aids. Cartilage conduction hearing aids (CCHA) represents a new amplification method. This study assessed the outcomes and evaluated the impact and its safety in the patients with microtia and aural atresia whose hearing dysfunction did not improve after surgery for ear reconstruction in our hospital. Hearing functions were evaluated with pure tone audiometry or sound field testing by behavioral audiometry and speech audiometry before and after CCHA fitting. As a result, there was a significant difference between unaided and aided thresholds (p < 0.001). Speech recognition threshold and speech discrimination level also significantly improved with CCHA. The average functional gains of 14 ears were 26.9 ± 2.3 dB. Almost all parents of the patients reported satisfaction with the performance of CCHA, and daily communication in children with hearing loss also became better than usual.

The Impact

<b><i>Introduction:</i></b> Cochlear implant (CI) surgery is a safe and standardized procedure in the presence of normal temporal bone anatomy. However, in the surgery of patients with chronic otitis media (COM), the surgeon may encounter several problems. The aim of this study was to evaluate the impact of COM with and without cholesteatoma on surgical and auditory outcomes of CIs. <b><i>Methods:</i></b> The study group consisted of 39 patients with COM who received CIs. Age- and gender-matched 38 standard CI patients served as controls. The surgical techniques and complications, pure tone audiometry (PTA) scores, speech discrimination scores (SDS), and the International Outcome Inventory for Hearing Aids (IOI-HA) questionnaire results of the groups were compared. <b><i>Results:</i></b> The presence of COM was associated with a higher rate of complication than controls. Staging the surgeries, presence or absence of cholesteatoma, and type of surgical technique were not associated with surgical outcomes and complications (<i>p</i> &#x3e; 0.05). There was no significant difference between the groups in terms of postoperative PTA scores, SDS, and IOI-HA scores (<i>p</i> &#x3e; 0.05). <b><i>Conclusion:</i></b> Postoperative complications like device failure and skin breakdown are increased in cases of COM compared to standard CI surgeries. However, that increase is not associated with staging the surgeries, presence or absence of cholesteatoma, and type of ear surgery performed. It is advocated to close the external ear canal and eustachian tube without mastoid obliteration in the presence of a radical mastoidectomy cavity, which will decrease the postoperative complication rates and allow for radiological follow-up with computed tomography for the possibility of cholesteatoma recurrence. The auditory benefits of CI in patients with and without COM are comparable.

Introduction The bone-anchored hearing aid (BAHA) is a bone conduction system that transmits the sound directly to the inner ear by surpassing the skin impedance and the subcutaneous tissue. It is indicated for patients with mixed, conductive and unilateral sensorineural hearing loss who did not benefit from conventional hearing aids (HAs). Although the benefits from BAHA are well demonstrated internationally, this field still lacks studies in Brazil. Objective To assess the auditory rehabilitation process in BAHA users through audiological, speech perception and tinnitus aspects. Methods Individuals with hearing loss were assessed before and after the implantation. The participants were subjected to pure tone audiometry in free field, functional gain audiometry, speech perception tests, tinnitus handicap inventory (THI) in open format, and to the visual analog scale (VAS). Results It was found that the participants benefited from the use of BAHA. The difference in the performance of the participants before and after the BAHA surgery was significant in terms of hearing acuity. There was no statistically significant difference in the speech perception tests. The tinnitus assessment showed that 80% of the participants scored slight tinnitus severity in THI after using a BAHA. Eighty percent of the participants classified their tinnitus as absent to mild in the VAS after the surgery. Conclusion Based on the results of the current study, we can conclude that the participants improved both the auditory perception and the tinnitus handicap.

Целью исследования было изучение качества жизни лиц с нарушениями слуха в разных возрастных группах. Обследованы 100 пациентов, обратившихся в городской сурдологический центр для взрослых в связи с нарушением слуха: 50 человек - 34-59 лет, 50 - 60 лет и старше, из которых 32 человека были пожилого возраста (60-74 года)и 18 - старческого (75-86 лет). Степень тугоухости оценивали на основании результатов тональной пороговой аудиометрии. Для исследования качества жизни все пациенты заполняли общий опросник MOS SF-36, отражающий физический и психологический компоненты здоровья, а также специальный опросник HHIА(E)-S для лиц с нарушениями слуха. Установлено, что шкала HHIА(E)-S демонстрирует высокую корреляцию со степенью тугоухости у пациентов моложе 60 лет ( R =0,98; достоверность различий на уровне p <0,05), которая снижается у пациентов 60 лет и старше ( R =0,94; различия в оценках при разной степени тугоухости недостоверны). Значительные трудности в старшей возрастной группе могут быть связаны с тем, что людям пожилого и, особенно, старческого возраста сложно пользоваться слуховыми аппаратами (или они для них неэффективны) и оценивать свои затруднения по шкалам опросника. Целесообразно использовать шкалу HHIА(Е)-S в качестве скринингового инструмента для раннего выявления тугоухости, направления пациентов к сурдологу и своевременного слухопротезирования. The aim of the research was to study the quality of life in hearing impaired patients of different age. 100 patients referred to the city audiology centre because of their hearing disorders were examined: 50 patients from 34 to 59 years old and 50 patients from 60 years and older, from which 32 patients were of older age (60 to 74 years old) and 18 of oldest age (75 to 86 years old). A degree of hearing loss was assessed according to results of pure tone audiometry. To study the quality of life all patients filled in the questionnaire MOS SF-36, which evaluates physical and psychological components of health, and the questionnaire HHIA(E)-S, designed specifically for patients with hearing disorders. The HHIA(E)-S scale was found to show high correlation with hearing loss degree in patients younger than 60 years old ( R =0,98 with statistically significant difference, p <0,05), with decreasing correlation in patients from 60 years and older ( R =0,98; no significant difference while assessing various hearing loss degrees). Considerable difficulties in this age group may be explained by the fact, that older and especially oldest patients have a challenge with hearing aids usage (or they are of low efficiency for them) and with assessing theirs difficulties on the questionnaire scales. The HHIA(E)-S scale is useful as a screening tool for early detection of hearing loss, referral of patients to an audiologist and prompt hearing aid fitting.

Целью исследования был сравнительный анализ жалоб и аудиологических показателей у пациентов сурдологического центра в зависимости от возраста. Представлены результаты обследования 300 первичных пациентов (случайная выборка), обратившихся к сурдологу-оториноларингологу в течение 1 мес. В группу молодых пациентов (19-44 года) вошли 40 человек; в группу среднего возраста (45- 59 лет) - 62 человека; в группу пожилых (60-74 года) - 100 человек; в группу старческого возраста (75-90 лет) - 98 человек. Обследование включало сбор жалоб и анамнеза, ЛОР-осмотр, тональную пороговую аудиометрию, импедансометрию, речевую аудиометрию в наушниках для выявления признаков центральных слуховых расстройств или в свободном звуковом поле для оценки эффективности слухопротезирования. Установлено, что для ранней диагностики тугоухости и профилактики возрастных сенсорнокогнитивных дисфункций целесообразно использовать не только результаты тональной пороговой аудиометрии, но и данные речевой аудиометрии, а также анализ субъективных жалоб. Результаты работы свидетельствуют о необходимости организации скрининга состояния слуха в рамках диспансеризации населения старше 60 лет. The aim of the study was a comparative analysis of complaints and audiological findings in patients of the audiological center depending on their age. The results of the examination of 300 fi rstly consulted patients (random sample) are presented. The group of young patients (19-44 years) included 40 people; middle age (45-59 years) - 62 people; elderly (60-74 years) - 100 people; senile age (75-90 years) - 98 people. The survey included the collection of complaints and anamnesis, ENT checkup, pure tone audiometry, impedancemetry, speech audiometry in headphones to detect the signs of Central Auditory Processing Disorder or in the free sound field to assess the effectiveness of hearing aids. It was found that for early diagnosis of hearing loss and prevention of age-related sensory-cognitive dysfunction, it is advisable to use not only the results of pure tone audiometry, but also the data of speech audiometry, as well as the analysis of subjective complaints. The results of the work indicate the need for hearing screening in the population over 60 years old.

Objective The efficacy of the Otologics Fully Implantable Hearing Device (MET) was assessed in adult patients with bilateral moderate to severe sensorineural hearing loss. Methods Surgical insertion of this totally implanted system was identical to the Phase I study. A repeated-measures within-subjects design assessed aided sound field thresholds and speech performances with the subject's own, appropriately fit, walk-in hearing aid(s) and the Otologics Fully Implantable Hearing Device. Results Six- and 12-month Phase II data will be presented. Ten patients were implanted and activated as part Phase II clinical trial. Three patients were lost to long term follow-up due to two coil failures and one ossicular abnormality preventing proper device placement. No significant differences between preoperative (AC = 59 dB, BC = 55 dB) and postoperative (AC = 61 dB, BC = 54 dB) unaided pure tone averages were noted (p < 0.05). Pure tone average implant aided thresholds (41 dB) were equivalent to that of walk-in-aided (37 dB) condition with no significant difference (p < 0.05) between patients’ walk-in-aided individual frequency thresholds and implant-aided thresholds. Word recognition scores and hearing in noise scores were similar between the walk-in-aided and for the implant-aided condition. Patient benefit scales will be presented at all end points. Conclusions Results of the Otologics MET Fully Implantable Hearing Device Phase II trial provide evidence that this fully implantable device is a viable alternative to currently available hearing aids in patients with sensorineural hearing loss.

Objectives -to determine the normative data of sentence speech intelligibility in a free sound field and to estimate the applicability of the Russian Matrix Sentence test (RuMatrix) for assessment of the hearing aid fitting benefit. Material and methods. 10 people with normal hearing and 28 users of hearing aids with moderate to severe sensorineural hearing loss were involved in the study. RuMatrix test both in quiet and in noise was performed in a free sound field. All patients filled in the COSI questionnaire. Results. The hearing impaired patients were divided into two subgroups: the 1st with high and the 2nd with low hearing aid benefit, according to the COSI questionnaire. In the 1st subgroup, the threshold for the sentence intelligibility in quiet was 34.9 ± 6.4 dB SPL, and in noise -3.3 ± 1.4 dB SNR, in the 2nd subgroup 41.7 ± 11.5 dB SPL and 0.15 ± 3.45 dB SNR, respectively. The significant difference between the data of both subgroups and the norm was registered (p

Background: A bone conducting implant is a treatment option for individuals with conductive or mixed hearing loss (CHL, MHL) who do not tolerate regular hearing aids, and for individuals with single-sided deafness (SSD). An active bone conducting implant (ABCI) was introduced in 2012 with indication in CHL, MHL, and SSD, and it is still the only ABCI available. With complete implantation of the active transducer and consequent intact skin, a decrease in infections, skin overgrowth, and implant losses, all common disadvantages with earlier passive bone conducting implants, could be expected. Our Ear, Nose and Throat Department, a secondary care center for otosurgery that covers a population of approximately 365,000 inhabitants, was approved to implant ABCIs in 2012. Objectives: Our aim was to conduct an evaluation of audiological and subjective outcomes after ABCIs. Method: A cohort study with retrospective and prospective data collection was performed.The first 20 consecutive patients operated with an ABCI were asked for informed consent. The main outcome measures werepure tone and speech audiometry and the Glasgow Benefit Inventory (GBI). Results: Seventeen patients accepted to participate and 15 were able to complete all parts. Six patients had CHL or MHL. In this group the pure tone audiometry tests are comparable with an average functional hearing gain of 29.8 dB HL. With bilateral hearing, the mean Word Recognition Score (WRS) in noise was 35.7% unaided and 62.7% aided. Ten patients had the indication SSD. With the hearing ear blocked, the pure tone average was >101 dB HL, compared to 29.3 dB HL in sound field aided. With bilateral hearing, the mean WRS in noise was 59.7% unaided and 72.8% aided. The mean of the total GBI score was 42.1 in the group with CHL or MHL and 20.6 in the group with SSD. Conclusions: The patients benefit from their implants in terms of quality of life, and there is a substantial hearing gain from the implant for patients with conductive or MHL. Patients with SSD benefit less from the implant than other diagnoses but the positive outcomes are comparable to other options for this group.

Introduction: Surgical treatment of conductive hearing loss runs the risk of damage to the inner ear in the mechanism of acoustic trauma. Aim: The aim of this study was to evaluate the function of the organ of Corti, expressed as bone conduction threshold at the frequency of 4000 Hz for selected operations: mastoidectomy and canal-wall-down procedure. Material and methods: The material was collected from patients with chronic otitis media in the Department of Otolaryngology and ENT Oncology, Collegium Medicum of Nicolaus Copernicus University in Bydgoszcz in 2004–2009. All patients were examined with pure tone audiometry threshold before surgery and at least three years after surgery. The analyzed group of patients was divided into subgroups depending on the type of operation according to To classification and procedures for resection: mastoidectomy and canal-wall-down procedure. The results were statistically analyzed. Results: In the analyzed period of three years after surgery there was no statistically significant difference between groups, although there were higher values for tympanoplasty type 1 with mastoidectomy compared with tympanoplasty type 1 without mastoidectomy - respectively 25.67 dB and 18.53 dB. In the study, there was no statistically significant the difference in bone conduction threshold for frequency 4000 Hz within the type 2 tympanoplasty according to Tosa comparing canal wall-up and canal-wall-down procedure. Conclusions: Mastoidectomy or canal-wall-down procedure do not affect the bone conduction threshold for a frequency of 4000 Hz after tympanoplasty in long-term observation.

Latar Belakang: Mikrotia didefinisikan sebagai daun telinga berukuran kecil dengan insiden sekitar 1 dari 7000-8000 ribu kelahiran, dengan insiden pada satu telinga sekitar empat kali lipat lebih banyak dibanding dua telinga. Rekonstruksi mikrotia merupakan salah satu prosedur cukup sulit pada bidang plastik rekonstruksi. Saat ini, penggunaan tandur tulang rawan iga autologus masih menjadi baku emas untuk rekonstruksi mikrotia. Tujuan: mengingatkan kembali para ahli THT tentang pertimbangan pemilihan rekonstruksi bersamaan pada kasus mikrotia bilateral dengan pencarian literatur berbasis bukti. Kasus: dilaporkan satu kasus mikrotia bilateral derajat 3, dengan hantaran tulang telinga kanan 60 dB, dan hantaran tulang telinga kiri 72,5 dB. Dengan pertimbangan memilih rekonstruksi bersamaan atau bertahap pada kedua telinga dan mengetahui prediksi perbaikan fungsi pendengarannya. Penatalaksanaan: aurikuloplasti tahap 1 dilakukan bersamaan pada kedua telinga. Skor Jahrsdoefer kedua telinga masing-masing 3 dan karena keterbatasan ekonomi dianjurkan menggunakan alat bantu dengar bukan BAHA untuk mengatasi hambatan komunikasi. Kesimpulan: penatalaksanaan mikrotia bilateral di bidang THT tidak hanya mencakup aspek rekonstruksi bentuk namun menekankan fungsi telinga sebagai alat berkomunikasi yang optimal. Kata kunci: mikrotia bilateral, ambang pendengaran, aurikuloplasti. ABSTRACTBackground:Microtia is defined as small sized ear with incidence approximately 1 in 7000-8000 births, which incidents in one ear is 4 times more compared to bilateral ear. Microtia reconstruction is one of difficult procedures in plastic reconstruction field. Recently, the use of rib cartilage autograft is still the gold standard for ear reconstruction. Purpose: to inform otorhinolaryngologist concerning simultaneous ear reconstruction in bilateral microtia case with evidence based method. Case: a third grade bilateral microtia, with the result of bone conduction are 60 dB for right ear dan 72,5 dB for left ear, the consideration to reconstruct both ear simultaneously or gradually, and how to predict the hearing improvement Management: first step of auriculoplasty was done in both ears, with Jahrsdoefer score is 3 for each ear, BAHA is adviceable but due to economic limitation the patients chose hearing aids. Conclusion: Bilateral microtia management in otorhinolaryngology does not only emphasize on ear reconstruction aspects but also to restore ear function as a means of optimal communicating.Keywords: bilateral microtia, hearing thresholds, auriculoplasty.

Objectives. Sound field (SF) audiometry tests are usually conducted in audiometric booths measuring greater than 2×2 m in size. However, most private ENT clinics carry about 1×1-m-sized audiometric booths, making SF audiometry testing difficult to perform. The aims of this study were to develop an SF audiometry system for use in smaller audiometric booths and compare its performance with traditional system.Methods. The newly developed SF audiometry system can yield an SF signal at a distance of about 30 cm from the subject’s ears. Its height can be adjusted according to the subject’s head height. We compared SF hearing results between the new SF system and the traditional SF audiometry system in 20 adults with normal hearing (40 ears) and 24 adults with impaired hearing levels (38 ears) who wore hearing aids. Comparative parameters included warble tone audiometry threshold, a speech reception threshold (SRT), and a speech discrimination score (SDS). For statistical analysis, paired t-test was used. The equivalence of both SF systems was tested using two one-sided test (TOST) with a margin of 5 dB (normal hearing participants) and 10 dB (hearing aids wearing participants).Results. Among participants with normal hearing, warble tone hearing thresholds of 0.5, 1, 2, and 4 kHz, average values of these four frequencies, and SRT were similar between the two systems (all <i>P</i>>0.05). Participants with hearing aids showed similar warble tone threshold and SRT (<i>P</i>>0.05) in both systems except for threshold of 4 kHz (<i>P</i>=0.033). SDS was significantly higher in the newly developed system (<i>P</i><0.05). TOST results showed equivalent SF audiometry results using either system.Conclusion. Audiometric results of the newly developed SF audiometry system were equivalent to those of a traditional system. Therefore, the small SF audiometry system can be used at small audiometric booths present in most private ENT clinics.
