Nine patients with malignant external otitis (MEO) were evaluated with Tc-99m bone scans, Ga-67 citrate scans, pluridirectional tomography, and computed tomographic (CT) scans in order to assess the role of each in the diagnosis and management of MEO. The Tc-99m and Ga-67 citrate scans were the most accurate studies in the initial identification of disease activity, while the return to normal or improvement of the Ga-67 citrate scan has been shown to correlate best with clinical resolution of MEO. CT demonstrated soft-tissue disease and central skull base osteomyelitis better than pluridirectional tomography. CT is excellent for localizing and following the progression of bone disease; however, because reossification of the skull base is a very slow process, CT cannot be used to follow accurately regression or inactivity of MEO affecting this area. CT is the best modality for following soft-tissue extension of MEO.
对9例恶性外耳道炎（MEO）患者进行了锝-99m骨扫描、枸橼酸镓-67扫描、多向断层扫描和计算机断层扫描（CT），以评估每种检查在MEO诊断和治疗中的作用。锝-99m和枸橼酸镓-67扫描是最初识别疾病活动最准确的检查，而枸橼酸镓-67扫描恢复正常或改善已被证明与MEO的临床缓解最相关。CT在显示软组织病变和中央颅底骨髓炎方面优于多向断层扫描。CT在定位和跟踪骨病进展方面非常出色；然而，由于颅底再骨化是一个非常缓慢的过程，CT不能用于准确跟踪影响该区域的MEO的消退或静止情况。CT是跟踪MEO软组织扩展的最佳方式。
