RESUMO

Since its publication in 1920 by Gillies, costochondral grafts have been used by surgeons to replace an injuredmandibular condyle and to reconstruct the temporomandibular joint. This procedure is currently applied in casesof congenital dysplasia, developmental defects, temporomandibular ankylosis, neoplastic disease, osteoarthritisand post-traumatic dysfunction. Over the years, various procedures for the reconstruction with this type of grafthave been described. In 1989, Mosby and Hiatt described a technique for setting the graft securely, reducing thespace between the graft and the mandibular area. In 1998, Monje and Martín-Granizo developed a variation ofthis method, enabling a precise adaptation of the costochondral graft to the remaining mandibular ramus. The aimof this study is to evaluate the functional and anatomic results of the costochondral graft treatment by green-stickfracture for reconstruction of the TMJ in the 10 years following the description of this technique. We carry out aretrospective study of thirteen cases of temporomandibular pathology (tumors, ankylosis and hypoplasia) treatedduring a period of ten years from 1998 to 2008. In all these cases, the technique described by Monje and Martín-Granizo was used: removal of the sixth rib, fixation to a titanium mini-plate using screws, making an internalcorticotomy in order to obtain a green-stick fracture of the outer cortex, providing adequate adaptation of thegraft to the mandibular ramus. The graft was then set in place, attaching it with titanium screws. This techniquewas successful in achieving optimal ossification, a good interincisal opening and satisfactory cosmetic results. Inconclusion, according to our experience, the green-stick fracture for the adaptation of costochondral grafts to theremaining mandibular ramus has presented outstanding results in the surgical treatment of temporomandibularpathology (AU)

RESUMO

The majority of cases of metastatic tumors involve the mandible and some the maxilla but they are considerably lesscommon in intraoral soft tissues. In addition, the primary tumor is known in the majority of cases; although in onethirdof such cases, metastasis is the first clinical manifestation. The most common primary tumors metastasizingto the mouth are lung carcinoma in men and breast carcinoma in women. An oral metastasis implies a serious prognosis,as in the majority of patients there is multiple organ involvement at the time of diagnosis. We present the caseof a 52-year old patient with renal pathology who came to the emergency room due to a rapidly increasing gingivaltumor. With the provisional clinical diagnosis of a pyogenic granuloma,the tumor was excised. Subsequent anatomopathologicalanalysis revealed a tumor metastasis compatible with clear-cell carcinoma, and its renal originwas confirmed by means of immunohistochemical techniques (AU)

RESUMO

Amyloidosis can be defined as an extracellular deposit of the amyloid fibrillar protein in one or more locations in the organism. Multiple clinical and biochemical forms of amyloid exist, and are characterized according to their fibrillar structural characteristics. The Red Congo stain presents green fluorescence when histologic cuts are observed by polarized light. The deposits of this substance can be focal in nearly any area of the organism, although the perivascular space tends to be affected. We present the case of a woman operated on for myeloma at the base of the cranium who showed no wider affectation at a later study. Fourteen years after the operation the patient showed a progressive growth of the submandibular gland that was diagnosed as a pathological amyloid deposit.

RESUMO

La amiloidosis se puede definir como el depósito extracelular de la proteína fibrilar amiloide de una o más localizaciones del organismo. Existen múltiples formas clínicas y bioquímicas diferentes de amiloide que se caracterizan según la estructura fibrilar características que poseen todas ell. La tinción de Rojo Congo hace que presente una birrefrigencia verde exclusiva cuando los cortes histológicos se observan bajo luz polarizada. Los depósitos de esta sustancia pueden ser focales prácticamente en cualquier zona del organismo, aunque suele afectar al espacio perivascular. Presentamos el caso de una mujer intervenida de un mieloma de base de cráneo sin que el estudio posterior demostrase una afectación más amplia, a los 14 años de la intervención presentó un crecimiento progresivo de la glándula submandibular que el estudio anatomopatológico diagnóstico depóstico patológico de amiloide (AU)
