- Ear Parade: A Call for Preventive Actions to Strengthen the Healthcare System against Hearing Loss(2021) LOPES, Paula Tardim; BENTO, Ricardo FerreiraIntroduction Approximately 10 million people in Brazil have some hearing impairment. Because of the natural progression of hearing impairment to presbycusis, coupled with the increasing number of young people exposed to the risk factors for early hearing loss, the social impact of hearing impairment is high. Objective A team of otolaryngologists and speech therapists conducted an unprecedented worldwide campaign in the primary health sector, aiming to reduce the global burden of hearing impairment with preventive measures. Methods A cultural information campaign called ""Ear Parade"" was developed. It lasted 3 months, during which SAo Paulo received information on the prevention of deafness and the importance of hearing rehabilitation to reduce prejudice against the use of hearing aids. Results The information was relayed through an art exhibition of public paintings, including 62 sculptures of ears, 2.40 meters high, which colored the city, elucidating the beauty of hearing. The media coverage impacted 170 million people, and at the end of the campaign, a nongovernmental organization was established to raise resources for hearing rehabilitation. In addition, an auction of the ear sculptures raised money toward hearing aid batteries and stem-cell research for hearing. Conclusion The present paper presents the effects of this campaign. Information dissemination is a powerful preventive measure for the primary healthcare system to reduce future treatment expenditures.
- Minimally Invasive Surgery for Intracochlear Schwannoma Removal and Simultaneous Cochlear Implantation(2016) BENTO, Ricardo Ferreira; GEBRIM, Eloisa Maria Mello Santiago; MAGALHÃES, Ana Tereza de Matos; PEREIRA, Larissa Vilela; FONSECA, Anna Carolina de OliveiraAbstract Introduction Hearing preservation has not yet been reported in patients undergoing resection of intracochlear schwannomas. This study describes a minimally invasive procedure for intracochlear schwannoma resection with simultaneous cochlear implantation that resulted in good hearing. Objective This study aims to describe a minimally invasive procedure for intracochlear schwannoma resection with simultaneous cochlear implantation. Data Synthesis The technique described in this study was developed for a 55-year-old male with a 20-year history of bilateral progressive hearing loss and tinnitus that had a mass in the left apical turn of the cochleameasuring 0.3 cm. Surgery accessed the apical turn of the cochlea. We performed mastoidectomy and posterior tympanotomy and removed incus and tensor tympani muscle to expose the cochlear apex. The tumor was identified and completely resected. After the cochleawas anatomically preserved, it was implanted with a straight electrode via round window insertion. The histopathological examination confirmed intracochlear schwannoma. Speech perception test revealed 100% speech recognition with closed sentences and the average audiometric threshold (500 to 2000 Hz) was 23 dB. Conclusion Our technique led to rehabilitation of the patient and improved hearing without damaging the intracochlear structure, making it possible to perform CI in the same procedure with good results.
- Disabling hearing loss prevalence in Juiz de Fora, Brazil(2012) BARAKY, Leticia Raquel; BENTO, Ricardo Ferreira; RAPOSO, Nadia Rezende Barbosa; TIBIRICA, Sandra Helena Cerrato; RIBEIRO, Luiz Claudio; BARONE, Marcelo M. V. B.; VASCONCELOS, Natalia BarakyData on the prevalence of disabling hearing loss (DHL) in Brazil is scarce, which impacts healthcare professionals' knowledge on the extent of the problem. Objectives: This study aimed at estimating DHL prevalence in the municipality of Juiz de Fora, Minas Gerais, to identify individual-related variables and find risk areas. Materials and Methods: This was a descriptive sectional population study held from January to October of 2009. We randomly selected 349 households with 1,050 individuals who with ages ranging between 4 days and 95 years. The data collection instruments were: WHO structured questionnaire, ENT examination and laboratory tests. Chi-square and Poisson regression models were used for analyses. Results: DHL prevalence was estimated at 5.2% (95% CI = 3.1 to 7.3) which was classified as moderate in 3.9% (95% CI = 0.001 to 0.134), severe in 0.9% (95% CI = 0.001 to 0.107) and profound in 0.4% (95% CI = 0.001 to 0.095). We found correlation between DHL and tinnitus; age over 60 years and low educational level. Conclusions: Our data obtained pointed to the need to create hearing health programs targeted to specific risk groups, promoting quality of life for hearing impaired patients.
- Assessment Protocol for Candidates for Bone-Anchored Hearing Devices(2022) UEDA, Cynthia Harumi Yokoyama; SOARES, Renata Marcial; JARDIM, Isabela; BENTO, Ricardo FerreiraIntroduction The technology regarding bone-anchored hearing devices has been advancing. Nevertheless, complications are still often reported, which can impair treatment adherence and lead to discontinuation of use. There is a lack of studies conducted in tropical countries, where complications can be even greater, as well as standardized protocols for selection, indication and evaluation. Objective To characterize implanted patients from a Brazilian public institution and describe the medical and audiological assessment protocols to which they were submitted during the selection process and in the follow-up after surgery. Method An observational, cross-sectional study evaluating the medical records of patients with hearing loss and ear malformations and describing the care protocol through which they were treated. Results The medical records of 15 patients were reviewed: 6 received transcutaneous implants, and 9, percutaneous implants; 9 patients reported some type of skin lesion, 2 reported pain on the follow-up visit, and 3 had osseointegration failure. The time between surgery and activation ranged from 2 to 9 months. The median scores on the sentences, Sentences in Noise and Monosyllable tests were 100%, 60% and 80%, respectively. Conclusion It was possible to characterize the patients who received implants at the institution. The patients performed well in silence and had greater difficulty in noise. Even patients who had complications did not complain about the audibility and sound quality. It is essential to develop a model and to standardize the assessment and follow-up methods aimed at the benefit of users of bone-anchored hearing devices, as well as to enable the technico-scientific development in this field.
- Evaluation of Functional Outcomes after Stapes Surgery in Patients with Clinical Otosclerosis in a Teaching Institution(2016) SOUZA, José Celso Rodriques de; BENTO, Ricardo Ferreira; PEREIRA, Larissa Vilela; IKARI, Liliane; SOUZA, Stephanie Rugeri; TORRE, Ana Adelina Giantomasi Della; FONSECA, Anna Carolina de OliveiraIntroduction Otosclerosis is a primary disease of the temporal bone that leads to stapes ankylosis. Hearing loss is the main symptom. Treatment includes surgery, medical treatment, and sound amplification therapy alone or in combination. Objective To evaluate the functional outcomes of patients with clinical diagnosis of otosclerosis undergoing primary stapes surgery in a teaching institution. Method Retrospective descriptive study. Results A total of 210 ears of 163 patients underwent stapes surgery. Of the 163 patients, 116 (71.2%) underwent unilateral surgery and 47 (28.8%) underwent bilateral surgery. Six of the 210 operated ears had obliterative otosclerosis. The average preoperative and postoperative air-bone gap was 32.06 and 4.39 dB, respectively. The mean preoperative and postoperative bone conduction threshold was 23.17 and 19.82 dB, respectively. A total of 184 (87.6%) ears had a residual air-bone gap <10 dB, and 196 (93.3%) had a residual air-bone gap ±15 dB. Two patients (0.95%) had severe sensorineural hearing loss. Conclusion Stapes surgery showed excellent functional hearing outcomes in this study. This surgerymay be performed in educational institutions with the supervision of experienced surgeons.
- Surdez pré-lingual: benefícios do implante coclear versus prótese auditiva convencional(2012) BITTENCOURT, Aline Gomes; TORRE, Ana Adelina Giantomassi Della; BENTO, Ricardo Ferreira; TSUJI, Robinson Koji; BRITO, Rubens deINTRODUCTION: The majority of patients with hearing loss, including those with severe hearing loss, benefits from the use of hearing aids. The cochlear implant is believed to achieve better results in a child with hearing loss in cases where the severity of disability renders hearing aids incapable of providing adequate sound information, as they require sufficient cochlear reserve so that acoustic detention occurs. OBJECTIVE: To assess if cochlear implants provide more benefit than conventional hearing aids in prelingually deaf patients. SUMMARY OF THE FINDINGS : The study was a systematic review of scientific papers selected by a search of the SciELO, Cochrane, MEDLINE, and LILACS-BIREME databases. Among the 2169 articles found, 12 studies proved relevant to the issue and presented an evidence strength rating of B. No publications rated evidence strength A. Seven of the studies analyzed were prospective cohorts and 5 were cross-sectional studies. CONCLUSION: Based on several studies, cochlear implants were demonstrated to be the best current alternative for bilateral severe or profound hearing loss, achieving better results in speech perception and development in prelingual children when compared to conventional hearing aids.
- Noise Attenuation Effects on Speech Recognition of Cochlear Implant Users Inside Helicopters(2021) CALDEIRA, Juliana Maria Araujo; GOFFI-GOMEZ, Maria Valeria Schmidt; IMAMURA, Rui; BENTO, Ricardo FerreiraBACKGROUND: The speech recognition levels of cochlear implant (CI) users are still incompatible with ICAO hearing requirements for civil aviation pilots testing in the noisy background condition of the helicopter cockpit. In this study, we evaluated noise attenuation effects on speech recognition in the same background condition. METHODS: The study involved the evaluation of 12 Portuguese-speaking CI users with post-lingual deafness and with a pure tone average up to 35 dB HL between 500 and 2000 Hz and up to 50 dB at 3000 Hz on at least one of the ears, and of three normal hearing pilots (controls). We performed speech recognition tests using sentences, numbers, and disyllables for all participants through the VHF radio. The assessment took place inside a helicopter with engine on, using three setups: 1) with headset without the active noise cancellation; 2) activating the noise cancellation system of the headset itself; and 3) connecting the speech processor directly to the helicopter radio system. RESULTS: The headset active noise-cancellation improved only the recognition of sentences. The direct connection system compared to the headset without anti-noise attenuation significantly improved all the recognition tests. The median for numbers was 90%, but the best score for disyllables recognition was 56%. DISCUSSION: The noise attenuation resources proposed in this study improved the CI users'speech recognition when exposed to the noisy helicopter cockpit. However, speech recognition of CI users still did not meet the standards of ICAO, which requires at least 80% for understanding disyllables in the speech in noise test.
- BAHA (Bone Anchored Hearing Aid) indicações, resultados funcionais e comparação com cirurgia reconstrutiva de orelha(2012) BENTO, Ricardo Ferreira; KIESEWETTER, Alessandra; IKARI, Liliane Satomi; BRITO, RubensINTRODUCTION: The bone-anchored hearing aid (BAHA) is a bone conduction hearing device that transmits sound directly into the inner ear. It is mainly used in patients with conductive hearing loss associated with aural atresia, but it is also used in those with mixed and sensorineural hearing loss. GOALS: To review the main indications for BAHA, to analyze the audiometric results and its benefits for patients and compare them with other treatment modalities, and to compare the literature data with our sample of 13 patients. METHOD: The research was performed using a database covering works in English, Spanish, and Portuguese, with no limitations in the years when the procedures were performed. We compared the literature data with our results for the 13 patients who underwent BAHA implantation between the years 2000 and 2009. RESULTS: Most of the studies showed that BAHA has great advantages over reconstructive surgery in terms of hearing results, complications, and disease recurrence. The postoperative results for our 13 patients were satisfactory and comparable with the results from the literature, with closure of the air-bone gap in 7 patients and achieving an air-bone gap of 10 dB in 6 patients. No postoperative complications were observed. CONCLUSION: BAHA is a better treatment option than reconstructive surgery for patients with bilateral deafness. It is a relatively simple surgical procedure with few complications and good hearing results. Recent studies have examined its use in conductive and unilateral sensorineural hearing loss.
- Implantable and Semi-Implantable Hearing Aids: A Review of History, Indications, and Surgery(2014) BITTENCOURT, Aline Gomes; BURKE, Patrick Rademaker; JARDIM, Isabela de Souza; BRITO, Rubens de; TSUJI, Robinson Koji; FONSECA, Anna Carolina de Oliveira; BENTO, Ricardo FerreiraIntroduction The complaints associated with the use of conventional amplifying hearing aids prompted research at several centers worldwide that ultimately led to the development of implantable devices for aural rehabilitation. Objectives To review the history, indications, and surgical aspects of the implantable middle ear hearing devices. Data Synthesis Implantable hearing aids, such as the Vibrant Soundbridge system (Med-El Corporation, Innsbruck, Austria), the Maxum system (Ototronix LLC, Houston, Texas, United States), the fourth-generation of Carina prosthesis (Otologics LLC, Boulder, Colorado, United States), and the Esteem device (Envoy Medical Corporation - Minnesota, United States), have their own peculiarities on candidacy and surgical procedure. Conclusion Implantable hearing aids, which are currently in the early stages of development, will unquestionably be the major drivers of advancement in otologic practice in the 21st century, improving the quality of life of an increasingly aged population, which will consequently require increased levels of hearing support.
- Idade no diagnóstico e no início da intervenção de crianças deficientes auditivas em um serviço público de saúde auditiva brasileiro(2012) PINTO, Meliane Melina; RAIMUNDO, Jeziela Cristina; SAMELLI, Alessandra Giannella; CARVALHO, Ana Claudia Martinho de; MATAS, Carla Gentile; FERRARI, Gisele Munhoes dos Santos; GARBI, Sérgio; GÂNDARA, Mara; BENTO, Ricardo FerreiraINTRODUCTION: The earlier the diagnosis and the intervention from the hearing impairment less will be the impact for the development of cognitive abilities, hearing and of speech from the child. OBJECTIVE: Characterize the age in the diagnosis and the beginning of intervention of the hearing loss and the accompaniment of the assisted children in a public Brazillian hearing health service - Espaço Reouvir from the Clinicas Hospital from the Medical School from the University of São Paulo. METHOD: Retrospective study with information from 166 medical records from children regarding the: gender; etiology, type, degree and laterality of the hearing impairment; age in the diagnosis and adaptation of the Hearing aids (HA) and accompaniment in the service. RESULTS: The sample was composed by 56% men and 44% women. The prevailing etiology was from multifactorial origin. The hearing loss from the neurosensory type occurred in 88,6% of the cases. The degree of moderate hearing loss was the most frequent (30,7%), symmetry in both ears was found in 69,9% of the cases and unilateral hearing loss in 2,4%. The average age in the diagnosis was of 5,46 years and in the intervention was of 6,86 years. A total of 96,98% of children had already completed the process of adaptation and 78,32% still remained in the accompaniment. CONCLUSION: The program Reouvir-HCFMUSP still receives children, both for diagnosis and or intervention in a late manner. However, still is possible the realization of the accompaniment of a significant number of users of the hearing aids, enabling a process of adaptation more effective.
