摘要
We report a unique case in which a 57-year-old man with an 8-year history of late recurrent post-tympanostomy tube otorrhea (PTTO) was found to harbor Bacillus subtilis, an aerobic endospore-forming bacillus that is typically resistant to chemical and physical agents because of its unique life cycle. Removal of the patient's tympanostomy tube resulted in complete resolution of his long-standing otorrhea. We also review the etiologies of and treatment strategies for early, late, chronic, and recurrent PTTO. We conclude that regardless of the etiology, a patient with persistent or recurrent PTTO should consider undergoing removal of the ventilation tube.
