Determine the role of 99m technetium scintigraphy for diagnosis in progressive necrotizing external otitis and assess the diagnostic criteria of this disease.
A retrospective study was conducted in 16 patients hospitalized for suspected progressive necrotizing external otitis. Patient characteristics, clinical features, imaging findings and disease course were recorded in order to evaluate the classical criteria of diagnosis.
The clinical course and complementary test results showed that 99m technetium scintigraphy lacked specificity for progressive necrotizing external otitis. These findings are in disagreement with those reported in the literature.
Patient characteristics and clinical course are key elements for early diagnosis of this disease. Scintigraphy findings are contributive only when bone lysis (which occurs late) can be evidenced. A prospective study would be required to confirm the lack of specificity of scintigraphy in progressive necrotizing external otitis.
确定锝-99m闪烁扫描术在进行性坏死性外耳道炎诊断中的作用，并评估该疾病的诊断标准。
对16例因疑似进行性坏死性外耳道炎住院的患者进行回顾性研究。记录患者特征、临床特征、影像学表现及病程，以评估经典诊断标准。
临床病程及辅助检查结果显示，锝-99m闪烁扫描术对进行性坏死性外耳道炎缺乏特异性。这些发现与文献报道不一致。
患者特征及临床病程是该疾病早期诊断的关键因素。仅当能证实存在骨质溶解（发生较晚）时，闪烁扫描术结果才有帮助。需要进行前瞻性研究以证实闪烁扫描术在进行性坏死性外耳道炎中缺乏特异性。
