Review of temporomandibular joint pathology. Part I : classification, epidemiology and risk factors
Pathology of the temporomandibular joint (TMJ) affects an important part of the population, though it is not viewed as a public health problem. Between 3-7% of the population seeks treatment for pain and dysfunction of the ATM or related structures. The literature reports great variability in the prevalence of the clinical symptoms (6-93%) and signs (0-93%), probably as a result of the different clinical criteria used. In imaging studies it is common to observe alterations that have no clinical expression of any kind. Radiographic changes corresponding to osteoarthrosis are observed in 14- 44% of the population. Age is a risk factor, though with some particularities. In elderly patients the…
Factores pronósticos del carcinoma oral de células escamosas en estadio avanzado. Estudio clínico de 191 casos
El carcinoma oral de células escamosas es el tumor epitelial maligno más frecuente en la cavidad oral y territorio maxilofacial, representando un 90-95% de los tumores malignos de esta localización, con una incidencia variable según el área geográfica, así en Estados Unidos y Europa presenta una incidencia en torno al 2-4%, mientras que en Asia se cifra en aproximadamente un 30%, probablemente motivado por diferentes hábitos tabáquicos y nutricionales. El paciente tipo es un varón entre los 50-70 años con hábitos tóxicos, aunque recientemente ha incrementado su incidencia en mujeres, pacientes menores de 40 años, y en pacientes sin hábitos tóxicos. En la carcinogénesis se ha implicado mucho…
A review of temporomandibular joint disease (TMJD). Part II : clinical and radiological semiology. Morbidity processes
The clinical signs and symptoms of greatest semiologic value in temporomandibular joint disease (TMJD) are muscle pain, joint pain, limitations in mandibular movement, and joint sounds. Imaging studies of the joint are very useful for establishing the diagnosis and for discarding other disease processes, though in many cases diagnostic error results from the detection of a large proportion of patients with alterations in the imaging studies but with no associated clinical manifestations. Panoramic X-rays and magnetic resonance imaging are the most commonly used complementary techniques for diagnosing TMJD. MRI may be regarded as the imaging technique of choice, particularly when studying th…
