Assessment Protocol for Candidates for Bone-Anchored Hearing Devices

Abstract

Introduction 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.

Comparative Clinical Effectiveness and Cost-Effectiveness of the Cochlear Osia System and Baha Attract System in Patients with Conductive or Mixed Hearing Loss or Single-Sided Deafness

“…The original percutaneous and more recent passive and active transcutaneous systems are commercially available in Australia, with the choice of system dependent on the severity of hearing loss and user preference. Given the majority of the Australian population lives in a tropical or subtropical climate with an associated increased risk of peri-abutment infections [ 4 , 5 ], transcutaneous BCHIs have become the standard of care in Australia.…”

Adaptação bilateral de próteses auditivas ancoradas no osso: reconhecimento de fala e localização sonora

“…Foram selecionados os pacientes, de ambos os sexos, já implantados do ambulatório. Todos os pacientes foram atendidos sob o mesmo protocolo (Ueda et al, 2022) e realizaram a cirurgia unilateral da PAAO por se enquadrarem nos critérios da Portaria GM/MS n° 2776 do Ministério da Saúde, pelo Sistema Único de Saúde.…”

“…Os limiares auditivos em campo livre e o reconhecimento de fala no silêncio e no ruído foram estaticamente melhores após a cirurgia. Os resultados mostraram que, de modo geral, os resultados obtidos com a PAAO acoplada à faixa elástica não diferiram significativamente dos resultados pós-cirúrgicos (ativação e seis meses de uso), tanto na audiometria tonal em campo livre, quanto na percepção de fala no silêncio e no ruído Ueda et al (2022),. estudaram 15 pacientes usuários de PAAO unilateral, que foram avaliados sob o mesmo protocolo pré-operatório.…”

“…No presente estudo foram utilizadas palavras monossílabas, com base no estudo realizado anteriormente(Ueda et al, 2022), onde a avaliação realizada com monossílabos mostrou maior consistência da resposta dos pacientes, provavelmente pelo fato de palavras monossílabas fornecerem menos pistas do que palavras maiores. Além disso, as sentenças fornecem mais pistas para o paciente, mas este deve acertar todas as palavras da frase para ser considerado um acerto.Os estudos levantados na literatura que realizaram a avaliação do reconhecimento de fala no silêncio com a adaptação bilateral da PAAO utilizaram como estímulo sentenças de, no mínimo, 3 palavras.…”
