Bone-related disorders of the jaw: A clinico-radiological diagnostic algorithm

Abstract

Bone-related disorders of the jaw (BRDJ) include a spectrum of non-neoplastic and neoplastic lesions of the maxillofacial region that have been recently classified into fibro-osseous lesions, giant cell lesions and osseous tumours. The histopathological features of BRDJ can be similar and overlie each other. Imaging is important in order to reach a specific diagnosis. However, the appearance of BRDJ on imaging is non-specific in some cases. Computed tomography (CT) and magnetic resonance imaging (MRI) are used for accurate localisation, characterisation of the tumour matrix, delineation of the lesion extension and establishment of the relation of BRDJ to the surrounding structures. Imaging is usually done to detect the relationship with the adjacent surrounding vital structures and to diagnose aggressive forms, malignant transformation and associated syndromes. The correlation of the demographic findings, the location and the clinical presentations with the imaging features are important for the diagnosis of BRDJ. The proposed clinico-radiological diagnostic algorithm with CT and MRI helps a specific diagnosis to be reached in some cases.

Manejo actual de la otitis externa maligna. Una revisión sistemática.

“…Dentro de las complicaciones de la otitis externa maligna se encuentran: sepsis por diseminación hacia la articulación temporomandibular, base del cráneo y cuello, formación de absceso intracraneal, mastoiditis aguda, osteomielitis de la base del cráneo y afectación de los nervios craneales. Según las revisiones utilizadas para el desarrollo de esta investigación, las complicaciones más observadas de los pacientes con OEM fueron en primer lugar la parálisis facial, seguida de las secuelas auditivas que incluyeron hipoacusia y parálisis de los músculos oculares (21)(22)(23)(24)(25).…”
