RESUMO
O Cisto àsseo Traum tico (COS) uma lesÆo rara, que tem alta incidncia na mand¡bula, principalmente na segunda dcada de vida. A descoberta do COS ocorre durante os exames de rotina, sendo assintom tica. A etiologia do COS geralmente encontra-se associada a algum tipo de trauma local, sem relaÆo causal com gnero ou raa. O tratamento desta lesÆo ocorre na grande maioria dos relatos por meio de exploraÆo cir£rgica, revelando-se eficaz e seguro. O objetivo deste estudo foi avaliar retrospectivamente os casos de COS, tratados entre janeiro de 1999 a julho de 2011. Foram avaliados 10.543 prontu rios, onde 12 pacientes apresentaram COS. Todos os casos ocorreram em pacientes que estavam na segunda dcada de vida, com mdia de idade de 15,2 anos. A mand¡bula estava envolvida em 100% dos casos, com elevada incidncia na s¡nfise (55%), seguido pelo corpo (36%) e ramo da mand¡bula (9%). Seis pacientes relataram a hist¢ria pregressa de trauma (2-9 anos) antes do diagn¢stico da lesÆo. Todos os pacientes foram submetidos
bi¢psia incisional associada
exploraÆo cir£rgica da cavidade c¡stica, o que representou o tratamento definitivo. O tempo mdio de proservaÆo foi de 35,7 meses. No per¡odo de acompanhamento (7 a 85 meses), nÆo foi observada recidiva da lesÆo. O tratamento por meio de cirurgia explorat¢ria, realizada no momento da bi¢psia, foi eficaz em todos os casos deste estudo
ABSTRACT
The simple bone cyst (SBC) is a rare asymptomatic injury diagnosed during routine examinations. The etiology of SBC is usually associated with a local trauma, with no relation with gender or race. The treatment through surgical exploration has proved to be effective and safe. The goal of this study was to evaluate retrospectively the cases of SBC, treated between January/1999 to July/2011. The study evaluated 10.543 clinical handbooks, in which 12 patients presented SBC. In all cases patients were in the second decade of life, with mean age of 15.2 years. Mandible was involved in 100% of the cases, with high incidence on the symphisis (55%), followed by body (36%), and mandibular ramus (9%). Six patients reported trauma (2-9 years) prior to the diagnosis. All patients were submitted to an incisional biopsy associated to a surgical exploration of the cystic cavity, that represented the definitive treatment. The average time of proservation was 35.7 months. In the follow-up period (7 to 85 months) was not observed any recurrence. The treatment through exploratory surgery, carried through the moment of the biopsy, was effective in all cases
