Multiple Peripheral Osteomas Related to Frontal Exposure by Bicoronal Incision.

Osteoma of the skull is a benign slow-growing osteogenic lesion typically composed of well-differentiated mature bone tissue. It is characterized by the proliferation of compact or cancellous bone and is found almost exclusively in the head and neck region. Central, peripheral, and extraskeletal are the major variants of craniofacial osteomas. Trauma, inflammation, developmental disorders, and genetic defects are considered their etiologic factors. Paranasal sinuses, especially frontal and ethmoidal sinuses, are the favorite locations of peripheral craniofacial osteomas.Peripheral osteomas are usually benign, innocuous lesions, but their size, prominence, and visibility on the face necessitate a surgical intervention.The authors describe a rare patient in whom multiple osteomsas were located in the frontal area likely related to an exposure of the site by bicoronal incision made 10 years earlier.
