【 摘 要 】

A 56-year-old man with a history of a right skull base fracture from a fall in the military 30 years ago presented to clinic with 6 months of progressive right-sided facial paralysis and a 1-year history of worsening odynophagia and dysphagia. He had been previously diagnosed at an outside facility with Bell’s palsy. Upon examination, the patient had House-Brackmann grade IV facial palsy on the right, tenderness to palpation over the right mastoid tip, and a palpable firm mass below the right mandible with fixation of the hyoid bone. Computed tomography of the neck showed a calcified mass extending from the right posterior skull base to the hyoid (Figure 1). There was narrowing of the facial canal as the nerve exits the stylomastoid foramen.
