Abstract
Osteomas are benign osteogenic tumors, which clinically manifest as well-defined and asymptomatic lesions. This article aims to report a case of extensive osteoma in the mandibular branch, addressing the main tools used for diagnosis and treatment modalities. Patient L.M.S, 55 years old, male, sought the service of Maxillofacial Surgery, reporting the appearance of a nodule on the face with evolution of 2 years. On physical examination, a significant volumetric increase was observed in the pre-auricular region on the left side, asymptomatic on palpation and non-bleeding. Computed tomography was requested, which showed a hyperdense bone lesion in the mandibular ramus region. The planned surgical proposal was for extra-oral access in the pre-auricular region on the left side, excision of the lesion by osteotomy followed by osteoplasty for the regularization of the remaining bone tissue and suture by planes. Subsequently, the piece was sent for histopathological analysis that identified the lesion as a compact osteoma. The patient was followed up for 1 and a half years, through clinical and radiographic evaluation, through which an excellent bone repair was observed, with no signs of recurrence. Carrying out the clink exam is essential for the diagnosis of osteoma, as it is an asymptomatic pathology. Due to the fact that it has a low probability of recurrence and does not present malignancy, a conservative approach can be performed with the appropriate postoperative follow-up. Therefore, it is concluded that the performance of a thorough clinical examination associated with the imaging and microscopic information are essential for a good clinical management of this pathology.
Highlights
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 CastroRodrigues et al, 2019)
This pathology can be classified based on the location of origin in endosteal when it originates from the endosteum, periosteal when it is originated on the surface of the bone tissue, or extraskeletal when it develops inside the muscle tissue
Osteomas are benign bone neoplasms resulting from the proliferation of compact or spongy bone that is clinically manifested as a well-defined, rounded, or oval mass, with firm consistency on palpation, usually asymptomatic and of slow growth
Summary
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 CastroRodrigues 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 They do not show a predilection for a specific age group; was found a higher occurrence in young adults.
