• Extracanalicular osteomas of the temporal bone are rare neoplasms. Eight new cases are reported and a review of the literature is presented. These tumors are benign, slow growing, and composed predominantly of mature bone. Although they may occur anywhere in the temporal bone, they are prevalent in the mastoid and squama. Except for cortical lesions that are seen initially as cosmetic deformities, these tumors are usually unsuspected roentgenographic findings. Treatment is indicated for symptomatic osteomas. Mastoid lesions are readily excised. Tumors involving the middle and inner ear are most frequently small and tend to remain stable in size; consequently they are usually managed expectantly.
