Premaxilla: an independent bone that can base therapeutics for middle third growth!

Abstract

Premaxilla, in its early descriptions, had the participation of Goethe. In our face, in a certain period of growth and development processes, premaxilla is an independent and, then, a semi-independent bone to finally be totally integrated to the maxilla. Formation of the premaxilla acts as a stabilization element inside the facial skeleton comparable to the cornerstone of a Roman arch and is closely related to the development of human face and its abnormal growth with characteristic malformations. Until when the premaxillary-maxillary suture remains open and offers opportunities to orthopedically influence facial growth to exert influence over facial esthetics and function? Contact with preliminary results in 1183 skulls from anatomic museums at USP, Unicamp and Unifesp led us to question therapeutic perspectives and its clinical applicability.

A descrição inicial da pré-maxila teve a participação de Goethe. Na face, em determinado período do crescimento e desenvolvimento, têm-se a pré-maxila como um osso independente e, depois, semi-independente para, finalmente, se integrar totalmente à maxila. A formação da pré-maxila atua como um elemento estabilizador dentro do esqueleto facial, comparável com a pedra angular de um arco romano, e está intimamente relacionada com o desenvolvimento da face humana e seu crescimento anormal, com malformações características. Até quando a sutura pré-maxilar-maxilar continua aberta e oferece oportunidades para se influenciar ortopedicamente o crescimento facial e modificar a estética e função da face? O contato com estudos preliminares em 1.183 crânios de museus anatômicos da USP, Unicamp e Unifesp nos induziu a questionar sobre as perspectivas terapêuticas e aplicabilidades clínicas.
