RESUMEN
The treatment for fungal sinusitis is general irrigation of the sinus or surgery. We report a case in which shin'iseihaito was used to treat fungal sinusitis. The patient was a 57-year-old man. On May 17, he underwent wisdom tooth extraction at the dentistry department of a hospital. Fungal sinusitis of the right maxilla was suspected on preoperative CT of paranasal sinuses. On June 19, he was introduced to the department of otolaryngology in the same hospital. The ostium of the right maxilla was widely open and there were fungal balls in the sinus. Saline irrigation was performed as an outpatient procedure and at home. On October 19, he was introduced to my clinic as he lives nearby. We prescribed him shin'iseihaito. On November 11, fungal balls were discharged when he was performing saline irrigation at home. The pathological diagnosis was Aspergillus. Although there is no previous report of shin'iseihaito for fungal sinusitis, it may be a useful treatment.
