Tratamento cirúrgico de osteoma em mandíbula – relato de caso

Abstract

Osteomas são neoplasias benignas que se caracterizam pela proliferação de osso maduro compacto ou esponjoso. Os locais de ocorrência mais frequentes são a mandíbula e os seios paranasais. O objetivo desse artigo é relatar diagnóstico e o tratamento cirúrgico de um osteoma periférico mandibular em paciente não sindrômico. O caso em estudo é o de um Paciente do gênero masculino, 40 anos, ASA I, procurou o serviço de Cirurgia Bucomaxilofacial do Hospital Universitário Oswaldo Cruz – PE com queixa de aumento de volume intraoral em região anterior de mandíbula, firme a palpação, bem delimitada e com cerca de 2cm. Após exame físico a hipótese diagnóstica levantada foi osteoma e torus mandibular. A proposta cirúrgica planejada foi acesso intra-oral, exérese da lesão, osteoplastia mandibular e encaminhamento do material colhido para análise histopatológica para confirmação do diagnóstico. A análise histopatológica confirmou a hipótese diagnóstica de osteoma périférico. O paciente foi acompanhado no pós-operatório e após 6 meses do procedimento cirúrgico não foi observado sinais de recidiva.

Surgical treatment of extensive peripheral osteoma in the mandibular ramus: Case report

“…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. Depending on its location and size, it can cause aesthetic and functional damage (Garcia et al, 2007;Neville et al, 2016;Starch-Jensen, 2017;Castro et al, 2020;). In the reported case, the volumetric increase in the region of the left mandibular ramus resulted in the occurrence of facial asymmetry.…”

“…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).…”

“…The etiology of osteomas, widely discussed in the literature, is still uncertain; it can be associated with conditions such as inflammatory reactions, embryological and genetic factors, continuous muscle action, osteogenic processes, and terminal stages of traumatic healing (Autorino et al, 2019, Aires, et al, 2020. In the craniofacial region, this lesion mainly Research, Society and Development, v. 10, n. 6, e4810615486, 2021 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v10i6.15486 affects the paranasal sinus and can also manifest in the mandible, external auditory canal, orbit, temporal bone, and pterygoid process (Fernandez et al, 2017;Castro et al, 2020). Maxillary manifestation is rare (Caubi, et al, 2013;Castro, et al, 2020).…”

“…They also do not show a predilection for a specific age group; however, was found a higher occurrence in young adults. (Starch-Jensen, 2017;Marcondes de Castro Rodrigues et al, 2019;Castro et al, 2020;).…”
