Lateral override 과두하골절에서 내시경을 이용한 관혈적 정복술 및 내고정의 결과
최은주(Eun-Joo Choi),차인호(In-Ho Cha),남 웅(Woong Nam) 대한구강악안면외과학회 2011 대한구강악안면외과학회지 Vol.37 No.1
Introduction: Endoscope-assisted open reduction and internal fixation (EAORIF) reduces the amount of facial scaring, but limitations, such as the possibility to convert to the open technique and the large learning curve, remain. Materials and Methods: The medical records of 19 patients diagnosed as lateral overridden subcondyle fractures and treated with endoscopeassisted open reduction and internal fixation at Yonsei University Health System from December 2006 to August 2010 were reviewed. Results: 11 patients underwent temporary discomfort or pain such as limitation of mouth opening, temporomandibular joint discomfort, lip paresthesia or facial weakness, but the symptoms disappeared within 3 months. There was no severe long-term complication except 2 patients with re-fractures of operated subcondyles. Conclusion: Subcondyle fracture with lateral overridden proximal segment is a better indication of endoscope-assisted open reduction and internal fixation than a condylar head/neck fracture, or medial overridden subcondyle fracture: allowing an anatomic reduction.

하악골 과두하부 골절 실험모델에서 견고정을 위한 플레이트 고정방법 연구
이원,강동희 대한두개안면성형외과학회 2011 Archives of Craniofacial Surgery Vol.12 No.1
Purpose: This study examined the biomechanical stability of four different plating techniques in the experimental model of mandibular subcondyle fracture. Methods: Twenty standardized bovine tibia bone samples (7 × 1.5 × 1.0 cm) were used for this study. Each of the four sets of tibia bone was cut to mimic a perpendicular subcondyle fracture in the center area. The osteotomized tibia bone was fixed using one of four different fixation groups (A,B,C,D). The fixation systems included single 2.0 mm 4 hole mini adaption plate (A), single 2.0 mm 4 hole dynamic compression miniplate (B), double fixation with 2.0 mm 4 hole mini adaption plate (C), double fixation with a 2.0 mm 4 hole mini adaption plate and 2.0 mm 4 hole dynamic compression miniplate (D). A bending force was applied to the experimental model using a pressure machine (858 table top system, MTS )until failure occurred. The load for permanent deformation, maximum load of failure were measured in the load displacement curve with the chart recorder. Results: Double fixation with a 2.0 mm 4 hole mini adaption plate and a 2.0 mm 4 hole dynamic compression miniplate (D) applied to the anterior and posterior regions of the subcondyle experimental model showed the highest load to failure. Conclusion: From this study, double fixation with an adaption plate and dynamic compression miniplate fixation technique produced the greatest biomechanical stability. This technique may be considered a useful means of fixation to reduce the postoperative internal maxillary fixation period and achieve early mobility of the jaw.
