Nasal patency and otorhinolaryngologic-orofacial features in children / Patência nasal e características otorrinolaringológicas e orofaciais em crianças

Abstract Introduction: Nasal obstruction is a common symptom in childhood, related to rhinitis and pharyngeal tonsil hypertrophy. In the presence of nasal obstruction, nasal patency may be reduced, and nasal breathing is replaced by mouth breathing. Orofacial and otorhinolaryngologic changes are related to this breathing mode. Objective evaluation of upper airways may be obtained through nasal patency measurement. Objective: To compare nasal patency and otorhinolaryngologic-orofacial features in children. Methods: One hundred and twenty three children, 6-12 year-old, and of both sexes underwent speech therapy evaluation, according to Orofacial Myofunctional Evaluation protocol, clinical and endoscopic otorhinolaryngologic examination and nasal patency measurement, using the absolute and predicted (%) peak nasal inspiratory flow values. Results: Lower values of absolute and estimated peak nasal inspiratory flow values were found in children with restless sleep (p = 0.006 and p = 0.002), nasal obstruction report (p = 0.027 and p = 0.023), runny nose (p = 0.004 and p = 0.012), unsystematic lip closure during mastication (p = 0.040 and p = 0.026), masticatory speed reduced (p = 0.006 and p = 0.008) and altered solid food swallowing (p = 0.006 and p = 0.001). Absolute peak nasal inspiratory flow was lower in children with pale inferior turbinate (p = 0.040), reduced hard palate width (p = 0.037) and altered speech (p = 0.004). Higher absolute values were found in children with increased tongue width (p = 0.027) and, higher absolute and predicted (%) in children with mild everted lip (p = 0.008 and p = 0.000). Conclusions: Nasal patency was lower in children with restless sleep, rhinitis signs and symptoms, hard palate width reduced and with changes in mastication, deglutition and speech functions. It is also emphasized that most of the children presented signs and symptom of allergic rhinitis.

Resumo Introdução: A obstrução nasal é um sintoma comum na infância relacionado a rinite e hipertrofia das tonsilas faríngeas. Na presença de obstrução nasal, a patência nasal pode estar reduzida e a respiração nasal ser substituída por respiração oral. Alterações orofaciais e otorrinolaringológicas estão relacionadas a esse modo de respiração. A avaliação objetiva das vias aéreas superiores pode ser obtida através da medida da patência nasal. Objetivo: Comparar a patência nasal e características otorrinolaringológicas e orofaciais em crianças. Método: Foram submetidas 123 crianças de seis a 12 anos, de ambos os sexos, a avaliação fonoaudiológica, de acordo com o protocolo de avaliação Miofuncional Orofacial, exame clínico e endoscópico otorrinolaringológico e medição da patência nasal, com o uso do pico de fluxo inspiratório nasal em valores absolutos e valores estimados (% pico de fluxo inspiratório nasal). Resultados: Valores mais baixos de pico de fluxo inspiratório nasal e % pico de fluxo inspiratório nasal foram encontrados em crianças com sono agitado (p = 0,006 e p = 0,002), relato de obstrução nasal (p = 0,027 e p = 0,023), rinorreia (p = 0,004 e p = 0,012), fechamento não sistemático dos lábios durante a mastigação (p = 0,040 e p = 0,026), velocidade mastigatória reduzida (p = 0,006 e p = 0,008) e alteração da ingestão de alimentos sólidos (p = 0,006 e p = 0,001). O pico de fluxo inspiratório nasal foi menor em crianças com conchas inferiores pálidas (p = 0,040), redução da largura do palato duro (p = 0,037) e alterações da fala (p = 0,004). Valores maiores foram encontrados em crianças com largura da língua aumentada (p = 0,027). Valores maiores de pico de fluxo inspiratório nasal e % de pico de fluxo inspiratório nasal foram observados em crianças com lábio levemente evertido (p = 0,008 e p = 0,000). Conclusões: A patência nasal foi menor em crianças com sono agitado, sinais e sintomas de rinite, redução da largura do palato duro e alterações nas funções de mastigação, deglutição e fala. Enfatiza-se também que a maioria das crianças apresentava sinais e sintomas de rinite alérgica.

Variables associated with mouth breathing diagnosis in children based on a multidisciplinary assessment.

PURPOSE: : This study was conducted to identify variables associated with mouth breathing diagnosis in children, based on multidisciplinary domains. METHODS: 119 children, six to 12 years old, underwent anamnesis, speech therapy (orofacial structures and stomatognathic functions), otorhinolaryngologic (OTRL) with clinical and endoscopic examinations, dental (occlusion) and physiotherapy (body posture and nasal patency) assessments. Nasal patency was evaluated using Peak Nasal Inspiratory Flow (PNIF) and the Nasal Obstruction Symptom Evaluation (NOSE) scale. A multiple logistic regression was performed considering breathing mode as the dependent variable and the co-variables from each multidisciplinary assessment as associated variables. RESULTS: Association with MB diagnosis was found in each professional domain with: nasal obstruction report (Odds ratio - OR=5.55), time of pacifier use (OR=1.25), convex facial type (OR=3.78), obtuse nasal angle (OR=4.30), half-open or open lip posture (OR=4.13), tongue position on the mouth floor (OR=5.88), reduced hard palate width (OR=2.99), unexpected contraction during mastication (OR=2.97), obstructive pharyngeal tonsils (OR=8.37), Angle Class II malocclusion (OR=10.85) and regular gingival maintenance (OR=2.89). CONCLUSION: We concluded that a multidisciplinary diagnosis is important, given that each evaluation domain, including OTRL, dental and speech therapy, presented variables associated with MB diagnosis. Body posture and nasal patency variables were not associated with MB.

RESUMO Objetivo Este estudo foi conduzido para identificar as variáveis associadas ao diagnóstico de respiração oral em crianças, baseado nos domínios multidisciplinares. Método Cento e dezenove crianças, de seis a 12 anos, realizaram uma avaliação abrangente composta por uma anamnese e exames fonoaudiológico (estruturas orofaciais e funções estomatognáticas), otorrinolaringológico (avaliação clínica e endoscópica), odontológico (conservação oral e oclusão) e fisioterapêutico (postura corporal e permeabilidade nasal). A permeabilidade nasal foi aferida utilizando-se o Pico de Fluxo Inspiratório Nasal (PFIN) e a escala NOSE (Nasal Obstruction Symptom Evaluation). Foi realizada uma regressão logística múltipla, considerando o modo respiratório como variável dependente e as covariáveis de cada avaliação multidisciplinar como variáveis associadas. Resultados Foi encontrada uma associação do diagnóstico de respiração oral com variáveis de cada domínio profissional: relato de obstrução nasal (Odds ratio - OR=5,55), tempo de uso de chupeta (OR=1,25), tipo facial convexo (OR=3,78), ângulo nasolabial obtuso (OR=4,30), postura de lábios entreabertos e abertos (OR=4,13), postura de língua no assoalho oral (OR=5,88), largura do palato duro reduzida (OR=2,99), contrações inesperadas durante a mastigação (OR=2,97), tonsilas faríngeas obstrutivas (OR=8,37), má oclusão classe II de Angle (OR=10,85) e estado gengival regular (OR=2,89). Conclusão Concluiu-se que o diagnóstico multidisciplinar é importante, uma vez que as avaliações dos domínios fonoaudiológico, otorrinolaringológico e odontológico obtiveram variáveis associadas ao diagnóstico de respiração oral. As variáveis relacionadas à postura corporal e permeabilidade nasal não foram associadas ao diagnóstico de respiração oral.

A comparison between neural response telemetry via cochleostomy or the round window approach in cochlear implantation.

UNLABELLED: There are two techniques for cochlear implant (CI) electrode placement: cochleostomy and the round window (RW) approach. OBJECTIVE: This study aims to compare neural response telemetry (NRT) results immediately after surgery to check for possible differences on auditory nerve stimulation between these two techniques. MATERIALS AND METHODS: This is a prospective cross-sectional study. Twenty-three patients were enrolled. Six patients underwent surgery by cochleostomy and 17 had it through the RW approach. RESULTS: Mean charge units (MCU) for high frequency sounds: patients submitted to the RW approach had a mean value of 190.4 (± 29.2) while cochleostomy patients averaged 187.8 (± 32.7); p = 0.71. MCU for mid frequency sounds: patients submitted to the RW approach had a mean value of 192.5 (± 22) while cochleostomy patients averaged 178.5 (± 18.5); p = 0.23. MCU for low frequency sounds: patients submitted to the RW approach had a mean value of 183.3 (± 25) while cochleostomy patients averaged 163.8 (± 19.3); p = 0.19. CONCLUSION: This study showed no differences in the action potential of the distal portion of the auditory nerve in patients with multichannel cochlear implants submitted to surgery by cochleostomy or through the RW approach, using the implant itself to generate stimuli and record responses. Both techniques equally stimulate the cochlear nerve. Therefore, the choice of approach can be made based on the surgeon's own preference and experience.

Comparação da telemetria de resposta neural via cocleostomia ou via janela redonda no implante coclear / A comparison between neural response telemetry via cochleostomy or the round window approach in cochlear implantation

Existem duas técnicas para inserção dos eletrodos do implante coclear (IC): Via cocleostomia ou via janela redonda (JR). OBJETIVO: Comparar a telemetria de resposta neural (NRT) no pós-operatório imediato, verificando se há diferenças na estimulação do nervo auditivo entre estas duas técnicas. MÉTODOS: Prospectivo e transversal. Foram avaliados 23 pacientes. Seis submetidos à cirurgia via cocleostomia e 17 via JR. RESULTADOS: Comparação das unidades de corrente médias (UCM) para sons agudos: via JR com média de 190,4 (± 29,2) e via cocleostomia 187,8 (± 32,7), p = 0,71. Comparação das UCM para sons intermediários: via JR, média de 192,5 (± 22) e via cocleostomia 178,5 (± 18.5), p = 0,23. Comparação das UCM para sons graves: via JR, média de 183,3 (± 25) e via cocleostomia 163,8 (± 19,3), p = 0,19. CONCLUSÃO: Este estudo não mostrou diferença na captação do potencial de ação da porção distal do nervo auditivo em pacientes usuários do implante coclear multicanal submetidos à cirurgia via cocleostomia ou via JR, utilizando o próprio implante para eliciar o estímulo e gravar as respostas. Portanto, ambas as técnicas estimulam de maneira igual o nervo coclear, e baseado nisto conclui-se, também, que realizar o implante coclear via cocleostomia ou RW é uma escolha que depende da experiência cirúrgica e opção do cirurgião.

Cognitive evoked potentials and central auditory processing in children with reading and writing disorders.

UNLABELLED: Learning disorders are often magnified by auditory processing disorders (APD). OBJECTIVE: This paper aims to verify whether individuals with reading and writing disorders and P300 latencies above the average also present altered Staggered Spondaic Word (SSW) and speech-in-noise test results suggestive of APD. MATERIALS AND METHODS: This is a cross-sectional cohort study. Twenty-one individuals with reading and writing disorders aged between 7 and 14 years were enrolled. RESULTS: All subjects had normal findings on ENT examination, audiological tests, and brainstem auditory evoked potentials. The average P300 latency (334,25 ms) of all patients was picked as a cutoff point to divide the subjects into two groups: group A with latencies above 335 ms, and group B with latencies below 335 ms. Individuals in group A underwent SSW and speech-in-noise testing. CONCLUSION: Altered results in the SSW and speech-in-noise tests suggestive of APD were found in the group of individuals with reading and writing disorders with P300 latencies above 335 ms.
