title: Management of osteomas of the paranasal sinuses.
abstract: Craniofacial osteomas are benign tumors of the skull base, often involving the paranasal sinuses. The frontal sinus is the most common site of involvement, followed by the ethmoid, maxillary, and sphenoid sinuses, respectively. The growth rate is very slow, and it may take many years for osteomas to become clinically apparent. The origin of these tumors has been ascribed to embryologic tissue maldevelopment, trauma, or infection. The tumors are hard and lobulated with an ivory-like appearance, often mixed with a coarse granular component. The bone is compact or cancellous, with vascular or connective tissue components. The complications of osteoma growth are obstruction of sinus ostia, extension into adjacent bones and the intracranial cavity, and displacement of anatomic structures. Management of uncomplicated sinus osteomas is controversial, since surgery involves serious potential risks. When surgery is performed, these tumors can be successfully managed via endoscopic, open, or combined techniques. This article reviews the clinical findings, diagnostic studies, and treatment of 16 patients with paranasal osteomas. The indications for surgical intervention are discussed.
