Abstract

La présente invention concerne un guide pour rhinoplastie, qui fournit une ligne de guidage utilisée pour positionner le nez de telle sorte que le pont du nez est redressé, lorsque la rhinoplastie est réalisée. Le guide pour rhinoplastie selon un mode de réalisation de la présente invention permet à un utilisateur d'établir la ligne centrale du nez et de tracer ainsi facilement la ligne centrale avant que la rhinoplastie ne soit effectuée. De plus, le guide pour rhinoplastie permet à l'utilisateur de mesurer si un implant est centré tandis que la rhinoplastie est réalisée, et permet à l'utilisateur de tracer une ligne centrale pour déterminer si le nez est asymétrique après que la rhinoplastie a été réalisée.
