The use of anterior pedicle tongue flap for closing palatal fistulae demonstrates to be a safe procedure with high success rates (81% in this paper) when correctly indicated.

Maxillary defects with buconasal/businusal communications are situations difficult to manage and solve. Several treatment options are available on the literature, each one with its indication. Temporal muscle flap is one of these options, being a technique that requires more experience of the surgeon to be properly performed and that is mainly indicated for difficult cases, large defects and those nonresponsive to simpler techniques. The main purpose of this paper is to report 3 clinical patients of the application of the temporal muscle flap for the closure of extensive oral defects. None of the patients had necrosis, nervous deficits, or any long-term changes. The authors conclude that the use of this flap was shown to be a viable, safe technique with low complication and high success rates, which may contribute to the rehabilitation of well-indicated patients.

O conhecimento do suprimento sanguíneo do seio maxilar, em particular da parede lateral, é de considerável importância devido à possibilidade de rompimento acidental de uma artéria durante os procedimento de elevação do assoalho do seio maxilar. Paciente do sexo feminino, 65 anos de idade, com histórico de complicação pós-operatória, após procedimento de elevação do seio maxilar realizado há três anos. Após avaliação tomográfica, foi observada a presença da artéria antral em posição atípica. Identificar e reconhecer essa estrutura anatômica pelo exame radiográfico pré-operatório, evita possíveis complicações hemorrágicas, durante e após o procedimento cirúrgico.Palavras-chave: Tomografia Computadorizada de Feixe Cônico.

A case report is described of a 65-year-old female, who reported a postoperative complication after a sinus augmentation that she had had 3 years before. After radiographic evaluation, it was observed the presence of antral artery in atypical position. The identification of this anatomical structure is very important, by preoperative radiographic examination, avoiding possible bleeding complications, during and after the surgical procedures.keywords: Cone-Beam Computed Tomography.
