Tratamiento de anquilosis tempomandibular en la infancia mediante artroplastia y distracción de tejidos blandos / Management of tempormandibular ankylosis during childhood by means of arthroplasty and soft tissue distraction

Los traumatismos que afectan a los cóndilos mandibulares pueden ocasionar una anquilosis de la articulación temporomandibular que, si se produce en edad de crecimiento, puede dar lugar a una deformidad facial con asimetría o retrognatia. Entre los diferentes tratamientos utilizados, la distracción osteogénica ofrece unas ventajas, entre ellas la posibilidad de aplicación en la infancia y la elongación de tejidos blandos. Presentamos un caso de anquilosis temporomandibular bilateral en una niña de 9 años, que tratamos con distracción extraoral tras resección del bloque anquilótico, pero sólo con la finalidad de elongar los tejidos blandos y mantener el espacio en la nueva cavidad glenoidea para evitar la reanquilosis y favorecer la remodelación del cóndilo (AU)

[Dermoid cyst of the floor of the mouth. A case report]. / Quiste dermoide de suelo de boca. Revisión a propósito de un caso.

This is the case of a young woman, 16-year-old, calling to our Department because of the appearance, in the floor of the mouth, of a mass progressively growing until about 5 cm diameter. Through fine needle biopsy was diagnosed of epidermoid cyst. Despite its size and infrahyoid site was removed successfully. Perusal review of last years bibliography and its variants.

[Osteomatous jaw lesions in familial adenomatous polyposis]. / Osteomas mandibulares en la poliposis adenomatosa familiar.

The first aim of this study is to assess the frequency of osteomatous jaw lesions in patients with a diagnosis of familial adenomatous polyposis (FAP), and a group of FAP-relatives from the FAP registry of Majorca (Balearic Islands, Spain). The second aim is to study the predictive significance of osteomatous jaw lesions in families with FAP. The study included forty-two people. Twenty-five patients and seventeen relatives. All individuals underwent pantomography. Osteomatous jaw lesions were diagnosed in 68% of FAP-patients, and 6% of FAP-relatives. The difference was statistically significant (p < 0.001). The sensitivity was 68%, the specificity 94% and positive predictive value 94%. This frequency of osteomatous jaw lesions agree with previous studies of FAP-patients (57-82%), but differ from these of the previous studies of FAP-relatives (16-18%). The available method detect APC (adenomatous polyposis coli) gene mutations in 48-82% of FAP families. In the families without detected mutation, non-informative study or non-available study, the screening is based in seriated sigmoidoscopy and study of the extraintestinals lesions of the FAP syndrome. The frequency of osteomatous jaw lesions in FAP-patients is greater than the observed in FAP-relatives (p < 0.001). Osteomas in families with FAP are of predictive significance.
