Abstract
In 2006, in this journal, we published "Giant Cell Reparative Granuloma of the Temporal Bone Treated With Calcitonin". At that stage, the biopsy-proven large temporal bone lesion was managed with 12 months of daily injections of calcitonin 100 units, which were self-administered without difficulty. The original computed tomographic (CT) scan revealed a large expansile lesion filling the majority of the temporal bone with a soft tissue component expanding bone over the middle cranial fossa and eroding the floor of the right glenoid fossa. The lesion decreased in size, the patient’s conductive hearing loss was completely reversed, and the patient remained asymptomatic for a 2-year period at last follow-up. CT scanning showed resolution of the soft tissue mass and significant new bone formation involving the glenoid fossa and mastoid cortex.
