title: Temporal bone pathology in an active case of glue ear.
abstract: A child aged 3 1/2 died from a cardiac condition after many and prolonged antibiotic courses: bilateral glue ear had been treated for the previous 18 months. Histopathology showed cholesterol granulomata in the mastoid air cells, with evidence of old hemorrhage, and of former inflammation of bone. The exudate was histiocytic with some giant cells. An 'orange spot' on the tympanic membrane was hyperaemic middle-ear mucosa, heavily infiltrated by plasma cells, lymphocytes and histiocytes. There was no evidence of hypersecretion. Some of the most abnormal areas were around the stapedial niche and the round window.
