Abstract
The coronal approach has been used for over a century by neurosurgeons to access to the anterior cranium. Indications for the coronal approach expanded from use in the correction of congenital skeletal anomalies to applications in acute maxillofacial trauma and secondary deformity correction, oncologic surgery and reconstruction, and esthetic surgery. Complications were such as injury to frontal branch of the facial nerve, motor nerve paralysis, hematoma under flap, trismus, ptosis, epiphora, infection and anterior temporal depression. $Medpor^{(R)}$ is made up of dense polyethylene connected in porous structures. It is easily shapable without collapsing the pores due to it's hardness and tissue growth takes place at the porosities. Based on these advantages, $Medpor^{(R)}$ has been used in augmentation and restoration in craniofacial defect. A temporal depression after the coronal approach for treatment of Le Fort III fracture was successfully reconstruction with $Medpor^{(R)}$ and we report this case with review of literature.
관상접근법 후 발생한 측두부 함몰의 기전은 아직 명확하지는 않으나 중측두동맥의 손상에 의한 측두지방대의 소실과 변위, 측두근의 부피감소, 봉합시의 잘못된 위치에 의해 발생된다. 이에 저자등은 관상접근법 후 발생한 측두부 함몰을 빠른 혈관화와 골조직의 성장, 낮은 합병증을 보이는 $Medpor^{(R)}$를 이용하여 심미적인 개선을 얻을 수 있었고 이후 현재까지 양호한 경과를 보이기에 문헌고찰과 함께 보고하는 바 이다.
