Maxillary sinus, Great work of Leonardo da Vinci!

Leonardo da Vinci is one of the greatest painters of all time.  Among his works, the Mona Lisa is his most famous. Although, he is famous as one of the greatest ever painters, he was an expert anatomist too.  As an oral and maxillofacial surgeon, I have always been especially interested in his anatomical works.  The Vitruvian Man, the drawing of Roman architect, is the icon of human body proportion.  Facial plastic surgeons strive for the golden facial ratio he demonstrated through his drawings.  

Interestingly, there is another story regarding his anatomical works.  He is the first person to describe the maxillary sinus.   His work on the maxillary sinus is very significant indeed.  Size, shape, location are all perfect in his drawings.  The relationships between the sinus and the teeth and the nasal cavity are also amazingly precise.  I wonder how he did the accurate dissections in the 15th century using only primitive knifes and saws?  In my opinion, he is a true genius!

CT로 만들어본 간단한 상악동 이미지입니다.  뼈이식 수술에 중점을 두고 도움이 될 만한 주변 해부학적 구조물을 위치와 크기를 따져서 비교했습니다.  저의 의견으로는 수직적으로는 코 바닥의 높이가 유용한 기준점이 되며, 전후방으로 볼 때에는 관골부벽의 위치가 유용한 기준점이 됩니다.
