Fotobiomodulação no tratamento do trismo em pacientes tratados por câncer de boca ou orofaringe: um ensaio clínico controlado randomizado / Photobiomodulation in the treatment of trismus in patients treated for oral or oropharyngeal cancer: a randomized controlled clinical trial

RESUMO Objetivo investigar a eficácia da associação entre a fotobiomodulação de baixa frequência e a terapia fonoaudiológica tradicional no tratamento do trismo, em pacientes tratados por câncer de boca ou orofaringe. Métodos ensaio clínico controlado, randomizado, longitudinal e prospectivo, realizado de acordo as normas da declaração CONSORT 2010. Para a coleta de dados, foi utilizado o questionário sociodemográfico, a avaliação clínica, a mensuração da abertura de boca por paquímetro, o protocolo de dor McGuill e o protocolo de qualidade de vida WHOQOL-Bref. A amostra foi composta por 30 participantes, de ambos os gêneros na faixa etária de 35-75 anos, divididos em dois grupos, controle e experimental, de forma controlada, mediante sorteio igualitário no que tange aos critérios de inclusão e exclusão. Resultados por meio dos dados analisados, observou-se que houve aumento da amplitude vertical de mandíbula em ambos os grupos, GC: p<0,005 e GE: p<0,001. Não houve correlação estatística entre os grupos na comparação da abertura de boca, p>0,19, assim como em relação à dor orofacial e à qualidade de vida, p= 0,72, ambas as avaliações após a intervenção fonoaudiológica, porém, com melhores resultados para o GE, p<0,001. Conclusão Conclui-se pela eficácia da intervenção fonoaudiológica tradicional e a associação com a fotobiomodulação de baixa frequência no tratamento do trismo. Para a dor orofacial e qualidade de vida, o tratamento associado é mais benéfico.

ABSTRACT Purpose to investigate the effectiveness of the association between low-frequency photobiomodulation and traditional speech therapy in the treatment of trismus in patients treated for oral or oropharyngeal cancer. Methods controlled, randomized, longitudinal and prospective clinical trial, carried out in accordance with the norms of the CONSORT 2010 declaration. For data collection, a sociodemographic questionnaire, clinical evaluation, measurement of mouth opening by caliper, the protocol of McGuill pain and the WHOQOL-Bref quality of life protocol. The sample consisted of 30 participants, of both genders, aged between 35-75 years, divided into two groups, control and experimental, in a controlled manner, through an equal draw with regard to the inclusion and exclusion criteria. Results through the analyzed data, it was observed that there was an increase in the vertical amplitude of the mandible in both groups, CG: p0.19, as well as in relation to orofacial pain and quality of life, p= 0.72, both assessments after the speech therapy intervention, however, with better results for the EG, p<0.001. Conclusion It is concluded that the traditional speech therapy intervention and its association with low-frequency photobiomodulation are effective in the treatment of trismus. For orofacial pain and quality of life, associated treatment is more beneficial.

The effectiveness of the cold therapy (cryotherapy) in the management of inflammatory parameters after removal of mandibular third molars: a meta-analysis

Introduction: Cold therapy (cryotherapy) is a common procedure recommended by dental surgeons after surgical removal of thirdmolars, which is an invasive intervention that often deals with an expressive inflammatory response. Objective: To investigate whether cryotherapy interferes with clinical outcomes such as pain, edema, and trismus in the postoperative period of mandibular third molar surgeries. Data Synthesis: An electronic search was conducted in the OVID, PubMed, VHL, Science Direct, Cochrane Library, and Web of Science databases, through March 2018. The eligibility criteria included clinical trials that evaluated the effect of cryotherapy in at least one of the following variables: pain, swelling, and trismus. Two independent reviewers assessed the studies. The methodological quality of each article was analyzed. The search strategy resulted in 1,088 articles. Following the selection process, 11 studies were included in the systematic review and 4 of them in the meta-analysis. High risk of bias was found in most of the studies according to the Cochrane Handbook assessment. Patients receiving cryotherapy had less edema than patients in the control group at second day follow-up (mean difference [MD]: -0.94; 95%CI [-1.49; -0.39]). There were no statistically significant results when comparing trismus between experimental and control group (MD: 0.43; 95%CI [-0.34;1.20]). There were insufficient available data to support influences in postoperative pain. Conclusions: Cryotherapy applied on thefirstday aftermandibular third molar removal can manage edema in the patients.Well-designed randomized clinical trials to test the efficacy of cryotherapy after surgical removal of third molars are needed to justify its indication (AU)

Trismus / Trismus

Se define el trismus como una contractura de los músculos masticadores de etiología variada. Se lo encuadra como uno de los síntomas comunes a varias afecciones. Las infecciones, los traumatismos, los tumores y algunas afecciones generales son capaces de provocar trismus. Es importante hacer un buen diagnóstico de la afección para poder instituir el tratamiento correcto. La mayoría de los trismus ceden con tratamiento kinésicos acompañado de tratamiento general con relajantes musculares y analgésicos. Cuando fracasan los tratamientos conservadores, la cirugía está indicada, teniendo especial cuidado en el trazado de las incisiones por la brida cicatrizal que puede originar

Estudo clínico comparativo dos efeitos de duas preparações de betametasona, sobre o edema, trismo e dor, decorrentes da remoção de terceiros molares retidos / Clinical study compairing the effect of two betamethasone preparations on swelling, trismus and pain after removal of impacted third molars

O objetivo deste trabalho foi avaliar, comparativamente, os efeitos de duas preparações farmacêuticas de betasona, sobre o edema, trismo e dor, decorrentes da remoção de terceiros molares mandibulares retidos. Os resultados demonstraram um melhor controle do edema e da dor pós-operátoria, quando a preparação de rápida absorção, por via oral, era utilizada. Com relação ao trismo, não foi observada uma diferença estatisticamente significante entre os dois tratamentos propostos

Assessment of the effectiveness of short wave therapy on pain and trismus following surgical removal of impacted mandibular third molar

Surgical removal of the impacted mandibular third molar often produces post-operative complications. Evaluation of the effectiveness of short wave therapy on post-operative pain and trismus was carried out. The results of the study have shown that the severity of pain as well as the relief of muscle spasm were evident
