- 7th Portuguese audiology conference and 11th workshop of the ESS-P.PORTOPublication . Tomé, David; Pinto, Ana Isabel; Lopes, Paula; Oliveira, Vasco; Carmo, Paulo do; Marques, AntónioLast year’s 7th Portuguese Audiology Conference and 11th Workshop, held at the School of Health, Polytechnic of Porto, Portugal, was entitled “Audiology in the Digital Era”, reflecting the boom in the application of technology and software in clinical and daily life.
- Acupuntura no tratamento de acufenosPublication . Maciel, Diana; Oliveira, VascoO acufeno é uma sensação auditiva de som sem estimulação externa. Sendo este sintoma muito comum na nossa população, e não tendo uma cura objetiva e concreta, mas sim diversas alternativas e terapias que fazem diminuir os acufenos percebidos pelo indivíduo, procurando melhorar a sua qualidade de vida. A Acupuntura é uma arte medicinal chinesa, onde através da inserção de agulhas em pontos específicos do nosso corpo se consegue obter um tratamento completamente natural e desprovido de contraindicações. O objetivo é avaliar o efeito da Acupuntura no tratamento de indivíduos com acufenos, através da administração da versão portuguesa do questionário Tinnitus Handicap Inventory (THI).
- Adaptation to european portuguese of the questionnaire Early Listening Function (ELF) – Função Auditiva Precoce (FAP)Publication . Carmo, Paulo Jorge Quintela Cardoso do; Lopes, PaulaIn children, hearing loss has adverse effects on the development of communication, in vocabulary, syntax, and expressive language, in speech production, and social and emotional development. Assessment of hearing loss can be performed quantitatively with psychoacoustic audiometric testing, such as pure tone audiometry, or physiological tests, such as otoacoustic emissions, and electrophysiological tests like auditory evoked potentials of the brainstem that allow quantitative assessment and topographic diagnosis. Qualitative assessment of hearing loss can use specific scales, such as Early Listening Function (ELF) developed by Anderson (2002), which is used by parents or caregivers of infants and children from 4 months to 3 years old.
- Age related hearing loss in Portugal: methods and mutationsPublication . Pereira, Marisa; Aparicio, M.; Matos, Tiago; Antunes, M.; Fialho, Graça; Caria, HelenaPresbycusis is a multifactorial disease that represents the damage of intrinsic and extrinsic factors, acting in the inner ear through life. Presbyacusis or age-related hearing loss (ARHL) is estimated to affect up to 1.5 billion of people aged 60 by 2025. The aim of this study was to genetically characterize individuals with presbycusis, for GJB6, NAT2, GRM7 genes and mtDNA haplogroups in order to evaluate contributions to ARHL diagnosis
- An alternative 3D numerical method to study the biomechanical behaviour of the human inner ear semicircular canalPublication . Santos, Carla F; Belinha, Jorge; Gentil, Fernanda; Parente, Marco; Jorge, Renato NThe vestibular system is the part of the inner ear responsible for balance. Vertigo and dizziness are generally caused by vestibular disorders and are very common symptoms in people over 60 years old. One of the most efficient treatments at the moment is vestibular rehabilitation, permitting to improve the symptoms. However, this rehabilitation therapy is a highly empirical process, which needs to be enhanced and better understood.
- Análise dinâmica do comportamento mecânico do ouvido médio com prótese totalPublication . Gentil, Fernanda; Marques, Marco; Garbe, Carolina; Santos, Carla; Parente, Marco; Martins, Pedro; Jorge, RenatoO presente trabalho tem como objetivo analisar e caracterizar o comportamento do ouvido médio quando uma prótese total substitui os elementos da cadeia ossicular de forma a solucionar problemas de surdez de transmissão. com base num modelo geométrico da cadeia ossicular saudável, a partir de imagens de TAC, foi criado um modelo onde uma prótese total foi incluída, assim como todos os objetos inerentes a esta adição. Foi assim efetuado o estudo dinâmico de vibrações forçadas para um modelo utilizando o método de elementos finitos. Foram obtidos os deslocamentos ao nível do umbo e da platina do estribo, para diferentes níveis de pressão sonora aplicada sobre a membrana timpânica, quando presente uma cartilagem na interface membrana-prótese de diferentes diâmetros e espessuras. Os resultados obtidos foram comparados com o modelo da cadeia tímpano-ossicular normal. A utilização deste modelo tem como objetivo conseguir definir a técnica que promove, da melhor maneira possível, a performance de uma prótese total no ouvido médio. Com este estudo pode-se afirmar que a reabilitação do ouvido médio com próstese do tipo TORP apresentará melhores resultados quando são utilizadas cartilagens de 4mm de diâmetro, com espessuras entre os 0.3mm e os 0.4mm.
- Analysis of eardrum pathologies using the finite element methodPublication . Gentil, Fernanda; Garbe, Carolina; Parente, Marco; Martins, Pedro; Ferreira, António; Jorge, Renato Natal; Santos, Carla; Paço, JoãoThis work investigates the effect of eardrum perforations and myringosclerosis in the mechanical behavior of the tympano-ossicular chain. A 3D model for the tympano-ossicular chain was created and different numerical simulations were made, using the finite element method. For the eardrum perforations, three different calibers of perforated eardrums were simulated. For the micro perforation (0.6 mm of diameter) no differences were observed between the perforated and normal eardrum. For the numerical simulation of the eardrum with the largest perforation caliber, small displacements were obtained in the stapes footplate, when compared with the model representative of normal ossicular-chain, at low frequencies, which is related with major hearing loss in this frequency range. For the numerical simulations of myringosclerosis, the larger differences in the displacement field between the normal and modified model were obtained in the umbo. When observing the results in the stapes footplate, there were no significant differences between the two models, which is in accordance to the clinical data. When simulating an eardrum perforation along with myringosclerosis, there is a decrease in the displacements, both from the umbo and the central part of the stapes footplate, often associated with a pronounced hearing loss. It could be concluded that the reduced displacement of the stapes footplate may be related to a greater hearing loss.
- Analysis of the combined exposure to noise and ototoxic substances—pilot studyPublication . Lopes, Marta; Tomé, David; Carmo, Paulo Cardoso do; Rodrigues, Matilde; Neves, PaulaOtotoxic substances have been associated to damage of the auditory system, and its effects are potentiated by noise exposure. The present study aims at analyzing auditory changes from combined exposure to noise and organic solvents, through a pilot study in the furniture industry sector. Audiological tests were performed on 44 workers, their levels of exposure to toluene, xylene and ethylbenzene were determined and the levels of noise exposure were evaluated. The results showed that workers are generally exposed to high noise levels and cabin priming filler and varnish sector workers have high levels of exposure to toluene. However, no hearing loss was registered among the workers. Workers exposed simultaneously to noise and ototoxic substances do not have a higher degree of hearing loss than those workers exposed only to noise. Thus, the results of this study did not show that the combined exposure to noise and the organic solvent is associated with hearing disorders.
- Apneia do sono e perda auditiva em Indivíduos do sexo masculinoPublication . Ventura, Cláudia; Morim, Filipe; Oliveira, VascoO Síndrome da Apneia Obstrutiva do Sono (SAOS) é uma perturbação respiratória relacionada com o sono, que consiste na obstrução do fluxo respiratório durante o sono por um período igual ou superior a dez segundos e mais do que cinco vezes por hora. Um dos efeitos mais claros desencadeados por este síndrome é a sensação de cansaço pela incapacidade de completar um ciclo de sono. O ciclo do sono é composto por cinco fases que podem durar de setenta a cento e vinte minutos. Durante este período ocorrem vários ciclos, podendo em cada noite realizar-se de quatro a seis ciclos.
