Squamous cell carcinoma and basal cell carcinoma can arise from the auricle and external auditory canal or they may spread from adjacent sites. It is a composite structure consisting of four parts, each ossifying independently and later fuses. For instance, a person who seeks medical care in response to a potential brain lesion early may see less growth of that lesion, and therefore less temporal lobe damage. Other symptoms include bleeding from the ear and bruising around the mastoid process. More common are fractures of the pterion, which is where the temporal bone joins with other major bones of the skull: the parietal, frontal, and sphenoid.
