A Rare Case of Hyoid Osteoma.

Solid primary tumors of the hyoid bone are extremely rare. Osteomas are benign, slow-growing, usually asymptomatic, and well-circumscribed tumors broadly attached to the bone surface composed of mature lamellar/cortical-type bone with unknown etiology. Osteomas commonly occur in bones formed by membranous ossification, almost exclusively occurring in the head and commonly involving the paranasal sinus, skull vault, mandible, and nasal bone. We discuss a rare case of osteoma involving the hyoid bone. [ABSTRACT FROM AUTHOR]
