Pseudomonas aeruginosa is often isolated in infections of the ear cleft. In some circumstances, this organism can cause serious petrous or peri-petrous lesions. Two pictures are seen: Malignant external otitis with severe headaches, signs of external otitis, and usually pseudomonas aeruginosa is isolated. This is usually seen in an elderly diabetic patient. Nerve paralysis is the main risk. The other complications, very grave in the past, are rare nowadays with the use of selective antibiotic treatment. Pseudomonas aeruginosa is also the causative organism in extensive osteitis of the skull base. Diagnostic problems are seen in case of specific infections or tumoral lesions. The treatment includes the same medications as for the malignant external otitis, as well as complete surgical excision.
铜绿假单胞菌常分离自耳裂感染。在某些情况下，这种微生物可导致严重的岩部或岩周病变。有两种情况：恶性外耳道炎伴有严重头痛、外耳道炎体征，通常分离出铜绿假单胞菌。这通常见于老年糖尿病患者。神经麻痹是主要风险。过去其他非常严重的并发症，如今因使用选择性抗生素治疗而罕见。铜绿假单胞菌也是颅底广泛性骨炎的病原体。在特定感染或肿瘤性病变的情况下会出现诊断问题。治疗包括与恶性外耳道炎相同的药物，以及完整的手术切除。
