Exostose of the frontal bone : A case report

IntroductionExostoses are benign, calcified bony protuberances that typically arise in the cortical region of bones, with an etiology that is still not well defined. However, some authors correlate them with genetic factors, local traumas, and systemic diseases such as Gardner's syndrome and cherubism. Clinically, they present as sessile, fixed lesions that are easily detectable, asymptomatic, painless, and slow-growing, and can be found in various regions of the body. CASE REPORT A young female of 21 years old attended the Oral and Maxillofacial Surgery consultation complaining of a hardened nodular lesion in the frontal region. The patient reported a local trauma in her childhood.A CT scan was performed and showed a delineated bony lesion was observed only in the outer table of the frontal bone, without invasion of the frontal sinus.To correct the defect, an osteotomy was performed using a surgical chisel, followed by osteoplasty with a Maxicute bur.DiscussionFrontal bone exostosis is a rare lesion of the facial skeleton and typically does not require surgical intervention, although it can lead to aesthetic concerns and emotional discomfort. Therefore, it is often recommended to correct the existing asymmetry, preferably through an approach that allows good visualization of the lesion and provides better aesthetic outcomes.
