Microanatomy of Philtral ridge

인중의 미세해부학적 고찰

Many efforts are made to achieve satisfactory cosmetic and functional result in the repair of cleft lip. However, repair may be complicated in many cases by distortion of the vermilion border, obliteration of the normal contour of the philtrum, and eclabium in spite of many methods used in these days. To achieve better results in cleft lip repair, thorough understandings of the relationship between the surface morphology of the upper and lower lip and the underlying musculature is necessary but reports about this topic is rare. So, our studies were performed on the full-thickness upper lips containing both philtral ridge up to columelar base and lower lip, 4 post-mortem specimens of 2 females and 2 males aged from 16 to 42, using serial histological sections taken in the transverse and vertical planes under light microscopy. Thorough understanding of the anatomical relationships is established and on the basis of our findings, we can postulate some criteria to create a normal and natural philtrum in a patient with a cleft lip, it would be necessary to restore the normal deep muscle attachments and superficial dermal attachments of the orbicularis muscle, to close the lip without tension, to restore thickness of the philtral ridge, and to minimise nonelastic scar tissue.

구순열 수술에서 인중의 해부, 형태, 기능적 재건에 도움을 받고자 상순 및 하순의 전층표본을 가지고 미세구조를 관찰하였으며, 자연스럽고 미적인 인중을 재건하기 위해서는 정상적 근육 부착의 재건과 구륜근 표층의 진피 부속물들의 회복과 장력 없는 상순의 접합, 진피 부속물들을 포함한 인중융기의 두께 회복 및 비탄력성 흉터 조직의 최소화가 필요하다고 사료되었다.
