ABSTRACT

RESUMO Objetivo investigar o possível impacto da angulação do osso hioide na segurança da deglutição de pacientes submetidos à laringectomia supracricóidea. Métodos série de casos de 13 adultos, entre 48 e 79 anos, majoritariamente homens (n=11), submetidos à laringectomia supracricóidea em pós-operatório inferior ou igual a dez meses. Realizaram videofluoroscopia da deglutição de 5 ml de líquido fino, 5 ml de alimento pastoso e sólido, em livre oferta. A medida do ângulo do osso hioide foi definida por duas linhas: uma tangente à margem superior do corpo do osso hioide e uma tangente ao ponto mais inferior de sua margem inferior, paralela ao plano horizontal da imagem. O desfecho de aspiração durante o exame seguiu a escala desenvolvida por Rosenbek et al. (1996). Resultados Dos 13 pacientes, 5 apresentaram aspiração silente e 8 não apresentaram aspiração. Dos 5 indivíduos com aspiração, apenas 1 manteve preservadas ambas as cartilagens aritenoides em sua reconstrução e a angulação do osso hioide foi abaixo de 60º, em todos os casos. Dos 8 indivíduos sem aspiração laringotraqueal, a maioria (n=5) apresentava as duas cartilagens aritenoides em sua reconstrução e a angulação do osso hioide foi acima de 60º, em todos os casos. Conclusão uma angulação maior que 60º do osso hioide parece favorecer a proteção das vias aéreas inferiores e promover maior segurança do mecanismo de deglutição.


ABSTRACT Purpose to investigate the possible impact of hyoid bone angulation on swallowing safety in patients undergoing supracricoid laryngectomy. Methods the case series comprised 13 adults, between 48 and 79 years-old, male in its majority (n=11), within ten months or less post-supracricoid laryngectomy and cricohyoidoepiglottopexy. All volunteers were submitted to videofluroscopy at rest and during swallowing of 5 ml of thin fluid, 5 ml of pureed consistency and dry solid food. Images were captured in lateral view. The hyoid angle was taken at rest and defined by two lines: a tangent to the upper margin of the body of the hyoid bone and a horizontal line, tangent to the lowest point of its lower margin. The aspiration was assessed using the scale developed by Rosenbek et al. (1996). Results five cases had silent aspiration and eight had no aspiration. In the group with silent aspiration, only one individual had both arytenoid cartilages preserved, while all individuals had the hyoid bone angle below 60º. In the group without aspiration, five individuals had both cricoarytenoids preserved, while all cases had the average hyoid bone angle above 60º. Conclusion the hyoid bone being at an angle greater than 60º seemed to increase the protection of the lower airways, promoting a safer swallowing mechanism.

ABSTRACT

Introducción: alteraciones de este aparato estilohioideo son frecuentes y se manifiestan por el alargamiento del proceso estiloides y también por la osificación del ligamento estilohioideo. Los cambios pueden ser asintomáticos o pueden desencadenar una serie de síntomas como el dolor en cabeza. Objetivo: determinar la prevalencia del alargamiento del proceso estiloide y de la osificación del ligamento estilohioideo en radiografías panorámicas, atendiendo a la distribución según edad, sexo y lado afectado. Métodos: se tomaron 300 radiografías panorámicas digitales de los archivos de un Servicio de Radiología Dental. Fueron seleccionadas al azar entre las realizadas en 2012, y evaluadas por un único examinador. Fueron consideradas las radiografías en las cuales el proceso estiloide del hueso temporal superaba en más de 1 cm el borde más inferior del cartílago del lóbulo de la oreja y aquellas en la que el ligamento estilohioideo aparecía radiopaco. Resultados: en este estudio, se encontraron 108 radiografías (36 por ciento) con estas condiciones. Hubo una mayor prevalencia de alargamiento del proceso estiloide y/o la osificación del ligamento estilohioideo en mujeres (63 por ciento); se presentó bilateralmente en 72 por ciento de los casos, con mayor prevalencia en el rango etario de 61 a 70 años. Conclusión: la prevalencia de alteraciones en el complejo estilohioideo en las radiografías analizadas fue de 36 por ciento, la mayoría con presentación bilateral; predominó en mujeres del grupo etario referido(AU)


Introduction: alterations of the stylohyoid chain are common, taking the shape of styloid process elongation and stylohyoid ligament ossification. Changes may either be asymptomatic or trigger a number of symptoms such as headache. Objective: determine the prevalence of styloid process elongation and stylohyoid ligament ossification in panoramic radiographs based on distribution by age, sex and affected side. Methods: examination was conducted of 300 digital panoramic radiographs from the registries of a dental radiology service. Radiographs were randomly selected from among those performed in 2012, and evaluated by a single researcher. The radiographs considered were those in which the temporal styloid process exceeded in more than 1 cm the lowermost edge of the earlobe cartilage and those in which the stylohyoid ligament was radiopaque. Results: the study found 108 radiographs (36 percent) meeting these requirements. There was a higher prevalence of styloid process elongation and/or stylohyoid ligament ossification among women (63 percent), whereas the condition was bilateral in 72 percent of the cases, with a predominance of the 61-70 age group. Conclusion: prevalence of alterations of the stylohyoid complex in the radiographs analyzed was 36 percent. Most alterations were bilateral. There was a predominance of women from the above-mentioned age group(AU)

ABSTRACT

INTRODUÇÃO: a cirurgia de avanço de mento isolado tem sido cada vez mais indicada para a correção de deficiência anterior da mandíbula, harmonizando o perfil e gerando alterações funcionais. OBJETIVO: essa pesquisa teve a finalidade de avaliar os efeitos da cirurgia de avanço de mento no tamanho da orofaringe e nas posições do osso hioide e da língua. MÉTODOS: a amostra constou de 22 radiografias cefalométricas de perfil de 11 indivíduos que se submeteram à cirurgia de mentoplastia de avanço isolada. Dessas radiografias, 11 retratavam o período imediatamente pré-cirúrgico (T0) e 11 o pós-cirúrgico de, pelo menos, quatro meses (T1). As radiografias foram digitalizadas e transferidas para o programa Radiocef Studio 2.0, por meio do qual foram feitas as medições entre os pontos demarcados. RESULTADOS: verificaram-se diferenças estatisticamente significativas entre T0 e T1 quanto à posição do osso hioide e da língua no sentido horizontal e ao tamanho da orofaringe. O osso hioide se apresentou posicionado mais anterior em T1 (p = 0,01), assim como a língua, aumentando o tamanho da orofaringe (p = 0,01). CONCLUSÃO: houve aumento do espaço aéreo da orofaringe com o posicionamento mais anterior da base da língua, bem como a reposição do osso hioide anteriormente.


INTRODUCTION: Advancement genioplasty has been increasingly indicated for the correction of anterior mandibular deficiency as it balances the patient's profile and generates functional changes. OBJECTIVE: Thus, the aim of this study was to assess the effects of advancement genioplasty in the oropharyngeal size and in the position of the hyoid bone and tongue. METHODS: The sample comprised 22 lateral cephalometric radiographs of 11 individuals who had undergone advancement genioplasty alone. Eleven of these radiographs depicted the immediate preoperative period (T0) and the other 11 the postoperative period after at least four months (T1). The radiographs were scanned and exported to the Radiocef Studio 2.0® software (Radio Memory Ltda., Belo Horizonte, MG, Brazil). The landmarks were then identified and automatically measured by the program. RESULTS: The results showed statistically significant differences between the horizontal position of the hyoid bone and tongue and in the oropharyngeal size. The hyoid bone and tongue were repositioned anteriorly after surgery (p = 0.01), thereby increasing the dimension of the oropharyngeal airspace (p = 0.01). CONCLUSIONS: The oropharyngeal dimension increased as the tongue base and hyoid bone were repositioned more anteriorly.

ABSTRACT

OBJETIVO: Avaliar a mastigação e a deglutição em mulheres com e sem desordem temporomandibular (DTM) e investigar a posição da mandíbula e do osso hioide, por serem estruturas importantes para a realização destas funções. MÉTODOS: Setenta mulheres foram avaliadas quanto à presença de DTM segundo o instrumento Critérios de Diagnóstico para Pesquisa de Desordem Temporomandibular, sendo que 34 delas, com DTM, constituíram o grupo de estudo (GE) e 36 participaram do grupo controle (GC). A avaliação da mastigação e deglutição foi baseada no Protocolo de Avaliação Miofuncional Orofacial com Escores (AMIOFE). As variáveis referentes à posição da mandíbula e osso hioide aferidas pela análise cefalométrica. RESULTADOS: Os indivíduos com DTM apresentaram diferença significativa quanto à postura de língua (p=0,03) e lábios (p=0,04) durante a função de deglutição, bem como a adoção mais frequente de um padrão mastigatório unilateral crônico (p=0,03). Além disso, apresentaram posição mais baixa do osso hioide em relação à mandíbula (p=0,00). CONCLUSÃO: A presença de DTM promoveu maior frequência de alterações miofuncionais orofaciais durante as funções de mastigação e deglutição. A maior distância entre o osso hioide e a mandíbula, bem como a presença da sintomatologia álgica, podem justificar, em parte, os comportamentos atípicos da língua e dos lábios observados no grupo com DTM. A repercussão da DTM sobre as funções alimentares em uma faixa etária jovem explica a importância do diagnóstico e da intervenção terapêutica precoce nestes indivíduos.


PURPOSE: To evaluate chewing and swallowing functions in women with and without temporomandibular disorder (TMD) and investigate the position of the mandible and the hyoid bone as they are important structures in the development of these functions. METHODS: Seventy women were evaluated in relation to TMD diagnosis according to the Research Diagnostic Criteria, among them, 34 composed the study group (SG) with TMD and 36 took part in the control group (CG). Evaluation of the masticatory and swallowing functions was performed according to the Protocol of Orofacial Myofunctional Evaluation with Scores. Mandibular and hyoid bone position variables were measured by cephalometric analysis. RESULTS: TMD subjects showed a significant difference on tongue (p=0.03) and lip (p=0.04) posture during swallowing function, and a more frequent adoption of a chronic unilateral chewing pattern as well (p=0.03). Moreover, they presented a lower position of the hyoid bone in relation to the mandible (p=0,00). Conclusion: TMD presence resulted on a higher frequency of myofunctional alterations during masticatory and swallowing functions. A greater distance from hyoid bone to the mandible in addition with the presence of painful symptom can justify, partly, the atypical behaviors of the tongue and lips observed on TMD group. The TMD repercussion on alimentaires functions in a young age group justifies the importance of an earlier diagnosis and therapeutic intervention in these individuals.

ABSTRACT

OBJECTIVE: This study aimed to evaluate the possibility of any correlation between disc displacement and parameters used for evaluation of skull positioning in relation to the cervical spine: craniocervical angle, suboccipital space between C0-C1, cervical curvature and position of the hyoid bone in individuals with and without symptoms of temporomandibular dysfunction. MATERIAL AND METHODS: The patients were evaluated following the guidelines set forth by RDC/TMD. Evaluation was performed by magnetic resonance imaging for establishment of disc positioning in the temporomandibular joints (TMJs) of 30 volunteer patients without temporomandibular dysfunction symptoms and 30 patients with symptoms. Evaluation of skull positioning in relation to the cervical spine was performed on lateral cephalograms achieved with the individual in natural head position. Data were submitted to statistical analysis by Fisher's exact test at 5%significance level. To measure the degree of reproducibility/agreements between surveys, the kappa (K) statistics was used. RESULTS: Significant differences were observed between C0-C1 measurement for both symptomatic (p=0.04) and asymptomatic (p=0.02). No statistical differences were observed regarding craniocervical angle, C1-C2 and hyoid bone position in relation to the TMJs with and without disc displacement. Although statistically significant difference was found in the C0-C1 space, no association between these and internal temporomandibular joint disorder can be considered. CONCLUSIONS: Based on the results observed in this study, no direct relationship could be determined between the presence of disc displacement and the variables assessed.

ABSTRACT

La investigación se realizó en base a las historias clínicas del Ateneo de Odontología de la ciudad de Rosario en el transcurso del año 1995, extrayendo datos de ellas y realizando mediciones sobre las teleradiografías de 43 pacientes. Se verificó la existencia de posiciones diferentes del hueso hioides con respecto a estructuras adyacentes: columna cervical y plano mandibular, en pacientes de ambos sexos, con distintos tipos de crecimiento rotacional del maxilar inferior y diskinesias orofaciales (deglución atípica y respiración bucal). De los 43 pacientes estudiados, 21 (48,9 por ciento) prsentaban crecimiento divergente del maxilar inferior, con edades comprendidas entre 5 y 9 años del sexo femenino. La respiración bucal se observó en 33 pacientes (78,7 por ciento) mientras que 31 pacientes (72,1 poir ciento) mostraron deglución atípica, quedando en evidencia la prevalecencia de diskinesias orofaciales en la población estudiada. Un único pacientes presentó localización del hioides al plano mandibular con distancia esperada, de los 42 pacientes restntes, 33 (76,7 por ciento) tenían localización con distancia aumentada del hioides y 20 de ellos (46,5 por ciento) respiración bucal y deglución atípica en todos los crecimientos rotacionales. Con respecto a la relación hioides-columna cervical, 9 pacientes presentaron localización esperada (20,9 por ciento) y entre los 34 pacientes restantes, 18 (41,9 por ciento) localización elevada en la norma, de los cuales, 12 (35,3 por ciento) tenían deglución atípica y respiración bucal en todos los crecimientos mandibulares. Este trabajo destaca la importancia de evaluar los cambios en la posición del hueso hioides concomitantes a diskinesias orofaciales, a través del análisis cefalométrico
