“…Osteoma is the term used to designate a benign osteogenic neoplasm, essentially restricted to the craniofacial skeleton, with a rare occurrence in other bones of the human body (Garcia et al, 2007;Starch-Jensen, 2017;Marcondes de Castro Rodrigues et al, 2019). This lesion is characterized by the proliferation of mature or spongy compact bone (Starch-Jensen, 2017;Ata-Ali & Ata-Ali, 2019) and is clinically well defined, and may have a sessile or pedicled base, usually asymptomatic and unitary, and which, depending on its location and size, can generate aesthetic changes associated with the occurrence of facial asymmetry and functional damage to phonation, occlusion and deglutition (Garcia et al, 2007;Starch-Jensen, 2017;Castro et al, 2020). This pathology can be classified based on the location of origin in endosteal when it originates from the endosteum (central region of the bone tissue), periosteal when it is originated on the surface of the bone tissue (periosteum), or extraskeletal when it develops inside the muscle tissue (Neville et al, 2016;Khandelwal et al, 2016;Marcondes de Castro Rodrigues et al, 2019;Castro et al, 2020).…”
