Purpose: The goals of a blow-out fracture reconstruction are to restore the osseous continuity, provide support for the orbital contents and prevent functional and anatomic defects. Over the past several years, a range of autogenous and synthetic implants have been used extensively in orbital reconstructions. None of these implants have any absolute indications or contraindications in certain clinical settings. However, in extensive blow-out fractures, it is difficult to restore support of the orbital contents, which can cause more complications, such as enophthalmos. This study examined the clinical outcomes of extensive or comminuted blow-out fractures that were reconstructed by the simultaneous use of a titanium mesh plate and $Medpor^{(R)}$. Methods: Eighty six patients with extensive orbital fractures, who were admitted between March 1999 and February 2007, were reviewed retrospectively. The patients' chart and CT were inspected for review. Twenty three patients were operated on with both a titanium mesh plate (Matrix MIDFACE pre-formed orbital plate, Synthes, USA) and $Medpor^{(R)}$ (Porex, GA, USA). The patients underwent pre-operative CT scans to evaluate the fracture site and measure the area of the fracture. A transconjunctival approach was used, and titanium mesh plates were inserted subperiosteally with screw fixation. $Medpor^{(R)}$ was inserted above the titanium mesh plate. The patients were evaluated post-operatively for enophthalmos, diplopia, sensory disturbances and eyeball movement for a period of at least 6 months. Results: No implant-related complications were encountered during the follow-up period. Enophthalmos occurred in 1 patient, 1 patient had permanent sensory disturbance, and 3 patients complained of ocular pain and fatigue, which recovered without treatment. Although there were no significance differences between groups, the use of 2 implants had fewer complications. Therefore, it can be an alternative method for treating blow out fractures. Conclusion: The use of both a titanium mesh plate and $Medpor^{(R)}$ simultaneously may be a safe and acceptable technique in the reconstruction of extensive blow-out fractures.

구강 악안면 영역에서 외상으로 인해 발생한 골절에 대한 치료로 관혈적 혹은 비관혈적인 골절의 정복을 시행할 수 있다. 그러나, 최적의 정복이 이루어지지 않았거나 부정 유합이 발생할 경우, 하악골과 중안모 간의 구조적 관계가 상실되어 부정교합이 일어날 수 있다. 이러한 부정교합은 외상 후 부정교합이라 정의되며 안정적인 턱관절 위치의 확보 후 악교정 수술, 교정치료, 교합 재형성 및 보철적 재건 등이 외상 후 부정교합의 치료방법으로 제시되고 있다. 안정적인 턱관절은 교합 회복 전 부정교합의 재발 및 교합 변화를 방지하기 위해 필수적이며, 중심위 및 적응된 중심위는 가장 안정적인 턱관절의 위치로 교합 회복의 시작점이다. 본 증례는 다발성 안면 골절의 정복 후, 외상 후 부정교합이 발생하여 전악 교합의 회복을 위해 중심위에서 선택적 교합 조정 및 임플란트 지지 고정성 보철물로 보철적 재건을 시행한 증례로 교합 기능적으로 양호한 결과를 얻었기에 이를 보고하고자 한다.
