Orotracheal intubation and temporomandibular disorder: a longitudinal controlled study / Intubação orotraqueal e disfunção temporomandibular: estudo longitudinal controlado

ABSTRACT BACKGROUND AND OBJECTIVES: To determine the incidence of signs and symptoms of temporomandibular disorder in elective surgery patients who underwent orotracheal intubation. METHODS: This was a longitudinal controlled study with two groups. The study group included patients who underwent orotracheal intubation and a control group. We used the American Academy of Orofacial Pain questionnaire to assess the temporomandibular disorder signs and symptoms one-day postoperatively (T1), and the patients' baseline status prior to surgery (T0) was also recorded. The same questionnaire was used after three months (T2). The mouth opening amplitude was measured at T1 and T2. We considered a pvalue of less than 0.05 to be significant. RESULTS: We included 71 patients, with 38 in the study group and 33 in the control. There was no significant difference between the groups in age (study group: 66.0 [52.5-72.0]; control group: 54.0 [47.0-68.0]; p = 0.117) or in their belonging to the female gender (study group: 57.9%; control group: 63.6%; p = 0.621). At T1, there were no statistically significant differences between the groups in the incidence of mouth opening limitation (study group: 23.7% vs. control group: 18.2%;p = 0.570) or in the mouth opening amplitude (study group: 45.0 [40.0-47.0] vs. control group: 46.0 [40.0-51.0];p = 0.278). At T2 we obtained similar findings. There was no significant difference in the affirmative response to all the individual questions in the American Academy of Orofacial Pain questionnaire. CONCLUSIONS: In our population, the incidence of signs and symptoms of temporomandibular disorder of muscular origin was not different between the groups.

RESUMO JUSTIFICATIVA E OBJETIVOS: Determinar a incidência de sinais e sintomas de disfunção temporomandibular (DTM) em pacientes de cirurgia eletiva submetidos à intubação orotraqueal. MÉTODOS: Estudo longitudinal controlado com dois grupos. O grupo de estudo incluiu pacientes que foram submetidos à intubação orotraqueal e um grupo controle. Usamos o questionário da Academia Americana de Dor Orofacial (AAOP) para avaliar os sinais e sintomas da DTM no primeiro dia de pós-operatório (T1) e os estados basais dos pacientes antes da cirurgia (T0) também foram registrados. O mesmo questionário foi usado após três meses (T2). A amplitude da abertura bucal foi medida em T1 e T2. Consideramos um valor p inferior a 0,05 como significativo. RESULTADOS: No total, 71 pacientes foram incluídos, com 38 pacientes no grupo de estudo e 33 no grupo controle. Não houve diferença significativa entre os grupos quanto à idade (grupo de estudo: 66 [52,5-72]; grupo controle: 54 [47-68], p = 0,117) ou gênero feminino (grupo de estudo: 57,9%; grupo controle: 63,6%, p = 0,621). No T1, não foram encontradas diferenças estatisticamente significativas entre os grupos quanto à incidência de limitação de abertura bucal (grupo de estudo: 23,7% vs. grupo controle: 18,2%, p = 0,570) ou amplitude de abertura bucal (grupo de estudo: 45 [40-47]vs. grupo controle: 46 [40-51], p = 0,278). Em T2, os resultados obtidos foram semelhantes. Não houve diferença significativa na resposta afirmativa a todas as perguntas individuais do questionário AAOP. CONCLUSÕES: Em nossa população, a incidência de sinais e sintomas de DTM de origem muscular não foi diferente entre os grupos.

Fatores biopsicossociais do Eixo II dos Critérios de Diagnóstico para Pesquisa das Desordens Temporomandibulares em indivíduos com disfunção temporomandibular muscular e migrânea / Biopsychosocial factors of Axis II of the Research Diagnostic Criteria for Temporomandibular Disorders in individuals with muscular temporomandibular disorder and migraine

RESUMO JUSTIFICATIVA E OBJETIVOS: Relacionar as variáveis biopsicossociais do Research Diagnostic Criteria for Temporomandibular Disorders com os grupos de pacientes com disfunção temporomandibular, com disfunção temporomandibular e migrânea e grupo controle. MÉTODOS: Estudo do tipo observacional transversal onde foram avaliados 280 pacientes consecutivos, divididos em 3 grupos: grupo I (140 indivíduos controle); grupo II (65 indivíduos com disfunção temporomandibular muscular) e grupo III (75 indivíduos com migrânea e disfunção temporomandibular muscular). Os critérios de exclusão foram indivíduos que apresentaram histórico clínico de processos inflamatórios musculares, espasmos musculares, contraturas e injúria traumática aguda na articulação temporomandibular. RESULTADOS: Os indivíduos do grupo III apresentaram associação com depressão grave (p<0,0001), grau 4 na variável intensidade da dor (p=0,004), sintomas físicos não específicos sem dor intensa (p<0,0001) e sintomas físicos não específicos com dor intensa (p<0,0001). Houve diferença significativa entre os gêneros feminino e masculino no grupo III (Z=2,59; p=0,001), evidenciando maior tempo de dor no gênero feminino. A porcentagem de mulheres no grupo III foi significativamente maior em relação aos homens (p=0,004). CONCLUSÃO: A relação entre as variáveis e os três grupos mostrou maior número de indivíduos acometidos com maior intensidade de sintomas no grupo III. Dessa forma, entende-se que a migrânea é uma condição mórbida frequentemente associada à disfunção temporomandibular, potencializando os sintomas descritos pelos pacientes. Há necessidade de avaliações clínicas multidisciplinares nesses indivíduos para que o tratamento seja otimizado, minimizando a morbidade e diminuindo os custos e o número de consultas prestadas aos pacientes.

ABSTRACT BACKGROUND AND OBJECTIVES: To relate biopsychosocial variables of Research Diagnostic Criteria for Temporomandibular Disorders to groups of patients with temporomandibular disorders, temporomandibular disorders and migraine and a control group. METHODS: This is a cross-sectional observational study where 280 consecutive patients were evaluated and distributed in three groups: group I (140 control individuals); group II (65 individuals with muscle temporomandibular disorders) and group III (75 individuals with migraine and muscle temporomandibular disorders). Exclusion criteria were individuals with clinical history of muscle inflammatory processes, muscle spasms, contractures and acute temporomandibular joint traumatic injury. RESULTS: Group III individuals had association with severe depression (p<0.001), level 4 in pain severity (p=0.004), unspecific physical symptoms without severe pain (p<0.0001) and unspecific symptoms with severe pain (p<0.00001). There has been significant difference between females and males in group III (Z=2.59; p=0.001), with longer pain duration among females. The percentage of females in group III was significantly higher as compared to males (p=0.004). CONCLUSION: The relationship between variables and the three groups has shown a higher number of individuals with more severe symptoms in group III. So, it is understood that migraine is a morbid condition often associated to temporo mandibular disorders, worsening symptoms referred by patients. There is the need for multidisciplinary evaluation of these individuals to optimize treatment and minimize morbidity, costs and the number of medical visits.
