Effect of preservation of the inferior and posterior borders on recurrence of ameloblastomas of the mandible

RESUMOO ameloblastoma é um tumor odontogênico benigno, porém agressivo, de origem epitelial, constituindo cerca de 1-3% de todos os tumores e cistos da mandíbula. Apresenta crescimento lento e persistente, localizado na maior parte dos casos na área de ramo de mandíbula e ocasionalmente associado com terceiros molares inclusos. As lesões são caracterizadas por uma infiltração agressiva para o tecido adjacente e as células tumorais restantes podem levar a morbidades múltiplas de recorrência. Dessa forma, pode ocorrer uma elevada taxa de recorrência local se não for adequadamente removido. Este artigo relata um caso de ameloblastoma multicístico previamente tratado com terapia conservadora que resultou no insucesso do tratamento e recidiva da lesão após oito anos. O exame clínico demonstrou extensa reabsorção óssea na região de hemimandíbula direita. Foi realizada biópsia incisional e exame histopatológico para confirmação diagnóstica. O tratamento proposto foi a ressecção total em bloco envolvendo além de hemimandíbula direita, a região de elementos dentários 31 e 32 com margem de segurança de dois centímetros. O protocolo radical cirúrgico com boa margem de segurança deve ser a opção para prevenir a recidiva destes tumores agressivos.

“…Multicystic ameloblastomas affect mainly young adults at the age of 35 years, without gender preference. It affects the mandible four times more than the maxilla, it is more frequent in the molar region and the mandibular ramus 1,3 ; however it can also be found in the maxillary sinus and nasal cavity. Since it produces very little symptoms, patients usually seek care when the tumor is already large.…”

“…In the literature we also find indications for electrocauterization, cryosurgery and the use of sclerosant agents as treatment options1. Image exams are essential in the post-op follow up, because over 50% of the recurrences happen in the first five years of post-operative 1,3 .…”

Mul ticystic ameloblastoma mainly affects adult patients between the third and seventh decades of life, frequently in the posterior region of the mandible. The resection of a mandible segment without adequate reconstruction produces serious esthetic and functional sequelae leading to a loss of quality of life. The objective of this study is to show that multidisciplinary treatment of ameloblastomas helps in total lesion excision associated with complete reconstruction of the damaged area. We present a 47-year-old male patient with an ameloblastoma in the posterior mandible who was treated with complete resection of a mandibular segment. Reconstruction, carried out during the same surgical procedure, was performed using an iliac crest bone graft fixed with titanium plates and screws. Rehabilitation was completed eight months later with teeth implants in the grafted area. The advantages of this procedure include recurrence risk reduction due to segmental resection, reliable mandibular reconstruction and less surgical procedures, allowing full rehabilitation within a shorter period of time.

Odontogenic tumours of the maxillofacial region presents with a large number of histologic patterns and are derived from the primordial tooth forming tissues. They can occur most commonly in mandible and maxilla. The recent WHO classification helps in developing the appropriate treatment plan and categorizing the tumours. The present chapter deals with various benign odontogenic tumours with their clinical presentation and management in detail, based on clinical scenarios.
