Disfonia e disfunção temporomandibular: há relação?

Factors associated with voice-related quality of life among patients with temporomandibular disorders

BACKGROUND

Research would be important for obtaining a better understanding of voice complaints among patients with temporomandibular disorders (TMD).

OBJECTIVE

The identification of predictors of voice disorders associated with TMD pain was made according to Diagnostic Criteria for TMD (DC/TMD) Axis I.

METHODOLOGY

Functional limitations were measured using the Jaw Functional Limitation Scales for mastication (JFLS-M), jaw mobility (JFLS-JM), and verbal and emotional expression (JFLS-VEE). Patients also completed the Hospital Anxiety and Depression Scale (HADS). The primary outcome was social-emotional and physical functioning as indicated by scores on the Voice-Related Quality of Life (V-RQOL) questionnaire. Multiple linear regression was used to model the relationship between the domains on the V-RQOL questionnaire and scores on the HADS and JFLS after adjusting for age, gender, DC/TMD diagnosis, pain intensity, and time since pain onset.

RESULTS

The HADS-D (B=-1.15; 95% CI, -1.718 to -0.587; p<.001) and JFLS-VEE (B=-0.22; 95% CI, -0.40 to -0.06; p=.008) were significant predictors of scores on the V-RQOL questionnaire.

CONCLUSION

Higher scores on depression measures and limitations in verbal and emotional expression could exacerbate voice problems among TMD pain patients. Future research should promote multidisciplinary treatments for TMD pain-related voice disorders.

Relación entre la articulación temporomandibular y la función vocal: una revisión de la literatura

El estudio de la articulación temporomandibular y su relación con la función vocal ha recibido poca atención por parte de los investigadores. Las principales repercusiones de esto inciden negativamente en la labor y en la toma de decisiones del clínico. El objetivo de este trabajo es analizar la evidencia que relaciona a la articulación temporomandibular con la función vocal, tanto normal como patológica. Se llevó a cabo una revisión de la literatura mediante el análisis de artículos encontrados en las bases de datos PubMed, EBSCOHost, Scielo y Scopus. La evaluación de cada trabajo se hizo según título, abstract y criterios de elegibilidad. Los artículos analizados evidenciaron asociación entre la articulación temporomandibular y la función vocal. La disfunción temporomandibular severa afecta negativamente la percepción de la voz, mientras que, el descenso mandibular permite mayor intensidad vocal, optimiza la resonancia y facilita el control de la frecuencia fundamental.
