Benign and Malignant Tumours of the Ear and Temporal Bone
Benign and malignant tumours of the temporal bone are rare but may involve a morphology and function of the temporomandibular joint. Among benign neoplasms, the most common are adenoma, chondroma, lipoma, meningioma, neurofibroma and schwannoma. Malignancies are usually represented by acinic cell carcinoma, adenocarcinoma, adenoid cystic carcinoma, basal cell carcinoma, squamous cell carcinoma, chondrosarcoma, osteosarcoma, haemato-lymphoid tumours (including lymphoma), rhabdomyosarcoma, melanoma, malignant neuroma and paraganglioma as well as metastatic lesions and infiltration by pharyngeal, parotid and central nervous system tumours. Bone-related tumours and tumour-like disease such as fibrous dysplasia, Paget’s disease, osteoma and exostosis may also be visible in such localization. Magnetic resonance and computed tomography are the method of choice for their evaluation. However, position emission tomography is applied for systemic spreading, while ultrasound is used to examine a spreading into head and neck lymph nodes.
