Inverting papilloma of the temporal bone.

Objective: Inverting papilloma of the temporal bone is exceedingly rare. The objective is to familiarize the clinician with the clinical presentation and prognosis of this entity.

Methods: Retrospective case study and literature review. Methods: Published reports of inverting papillomas originating in the temporal bone were reviewed in conjunction with two cases presenting at the University of Texas Medical Branch (Galveston, TX).

Results: Inverting papillomas of the temporal bone are frequently associated with persistent middle ear effusion and ipsilateral sinonasal tumors and display a higher incidence of malignancy.

Conclusions: Successful management of these tumors requires an aggressive surgical resection. Adjuvant radiation therapy is recommended in patients with malignant changes.
