Resumo: | Anatomic knowledge on the zygomatic fossa is of primary importance to improve the regional anesthetic technique of the maxillary nerve. Few reports in the literature have addressed the trajectory of the maxillary nerve and its branches in this region; thus, this study aimed at presenting information about the trajectory of these nerves. Thirty human half-heads of both genders were fixed in 10% formalin and demineralized in 5% nitric acid, and the maxillary nerve was dissected since its origin on the pterygopalatine fossa until penetration into the inferior orbital fissure. It was observed that the maxillary nerve sends one to three posterior superior alveolar branches and tuberal descendent branches, which supply the soft tissue structures of the region. The posterior superior alveolar nerves are inferiorly oriented near the maxillary tuberosity, where they penetrate the alveolar canals with the posterior superior alveolar artery and send small nerve branches that continue in an extraosseous trajectory. This study found that nearly 2/3 of the trajectory of the maxillary nerve is located in the zygomatic region, with a short segment (1/3) in the pterygopalatine fossa. |

O conhecimento anátomo-cirúrgico da região zigomática é fundamental para o aprimoramento de técnicas anestésicas tronculares do nervo maxilar. A literatura pouco se refere à trajetória do nervo maxilar e seus ramos nessa região, portanto, o presente estudo tem como objetivo esclarecer o percurso desses nervos. Foram dissecadas ao microscópio cirúrgico MC900 (D.F.Vasconcelos), 30 hemicabeças humanas, de ambos os sexos, que foram previamente formolizadas a 10% e desmineralizadas em ácido nítrico a 5%. Observou-se que o nervo maxilar, desde sua origem na fossa pterigopalatina até penetrar na fissura orbital inferior, emite de um a três ramos alveolares superiores posteriores e ramos tuberais descendentes que vão para estruturas moles da região. Os nervos alveolares superiores posteriores, descem adjacentes à tuberosidade da maxila, na qual penetram através dos canais alveolares junto com a artéria homônima e podem emitir filetes nervosos que continuam trajeto extra-ósseo. Contrariando os achados da literatura, com este estudo observou-se que o nervo maxilar apresenta praticamente dois terços de sua trajetória na região zigomática e o restante na fossa pterigopalatina.
