Acute bacterial (suppurative) otomastoiditis responds to antibiotic treatment; radiologic study is required only when there is clinical suggestion of coalescent mastoiditis, intracranial complications, or an underlying chronic disease. Computed tomography (CT) is the method of choice for evaluating otogenic intra- or extra-cranial complications. CT scans can show stages of disease progression when infection has spread by way of soft tissue, blood, and bone pathways into the dural venous sinuses, meninges, labyrinth, facial nerves, epidural and other intracranial spaces. When there is clinical suggestion of acute coalescent mastoiditis, a CT scan of the temporal bone can confirm the presence of rarefying osteitis, coalescence of the air cells, and subperiosteal abscess.
急性细菌性（化脓性）耳乳突炎对抗生素治疗有反应；仅当有融合性乳突炎、颅内并发症或潜在慢性病的临床迹象时才需要进行影像学检查。计算机断层扫描（CT）是评估耳源性颅内或颅外并发症的首选方法。当感染通过软组织、血液和骨途径扩散到硬脑膜静脉窦、脑膜、迷路、面神经、硬膜外和其他颅内间隙时，CT扫描可以显示疾病进展的阶段。当有急性融合性乳突炎的临床迹象时，颞骨CT扫描可以确认是否存在骨质稀疏性骨炎、气房融合和骨膜下脓肿。
