Midfacial degloving approach는 중안면부에 대한 접근시 비교적 광범위한 수술시야의 확보가 가능하고, 술 후 중안모에 반흔을 남기지 않는 심미적 장점이 있다. 특히 중안면부의 광범 위한 골절과 비골 복합 골절을 동반한 중안면부 골절 수복에 이용되어 골절부에 대한 적절한 시야 확보로 정확한 관혈적 정복술이 가능하며 필요시에는 자가 늑골 등을 이용한 비 성형술이 가능하다는 장점이 있다. 이에 저자 등은 중안면부 복합골절의 치료시 midfacial degloving approach을 통해 중안면골의 관혈적 정복술 및 비 재건술을 시행한 증례에 대하여 문헌 고찰과 함께 보고하는 바이다.

Background: Asymmetry of the infraorbital rim can be caused by trauma, congenital or acquired disease, or insufficient reduction during a previous operation. Such asymmetry needs to be corrected because the shape of the infraorbital rim or midfacial skeleton defines the overall midfacial contour. Methods: The study included 5 cases of retruded infraorbital rim. All of the patient underwent restoration of the deficient volume using polyethylene implants between June 2005 and June 2011. The infraorbital rim was accessed through a subciliary approach, and the implants were placed in subperiosteal space. Surgical outcomes were evaluated using preoperative and postoperative computed tomography studies. Results: Implant based augmentation was associated with a mean projection of 4.6 mm enhancement. No postoperative complications were noted during the 30-month follow-up period. Conclusion: Because of the safeness, short recovery time, effectiveness, reliability, and potential application to a wide range of facial disproportion problems, this surgical technique can be applied to midfacial retrusion from a variety of etiologies, such as fracture involving infraorbital rim, congenital midfacial hypoplasia, lid malposition after blepharoplasty, and skeletal changes due to aging.

Background: Midfacial fractures frequently involve the maxillary sinus, leading to maxillary sinus pathology. We aimed to examine the incidence and contributing factors of maxillary sinus pathology in patients who underwent open reduction and internal fixation (ORIF) for midfacial fractures. Methods: A retrospective analysis was conducted on patients who underwent ORIF for midfacial fractures at our department over the past 10 years. The incidence of maxillary sinus pathology was identified clinically and/or by computed tomography findings. Factors that significantly influenced the groups with and without maxillary sinus pathology were examined. Results: The incidence of maxillary sinus pathology in patients who underwent ORIF for midfacial fractures was found to be 11.27%, with sinusitis being the most common pathology. Maxillary sinus pathology was significantly associated with the presence of a blowout fracture involving both the medial and the inferior orbital walls. Factors such as sex, age, diabetes mellitus, hypertension, smoking, inflammatory disease, follow-up period, use of absorbable plates, and use of titanium plates did not have a significant impact on the development of maxillary sinus pathology. Conclusion: The incidence of maxillary sinus pathology in patients who underwent ORIF for midfacial fractures was relatively low, and in most cases, it resolved without the need for specific treatment. Consequently, there may not be a significant need for concern regarding postoperative maxillary sinus pathology.

Malocclusion is a serious complication of open reduction surgery for facial fractures. It is often caused by the lack of adequate consideration for the occlusal relationship before the trauma and intermaxillary fixation during the operation. This is a case report of postoperative malocclusion that occurred in a patient with a midfacial complex fracture.

A 14-year-old girl had a midfacial trauma event caused by hitting against an opening door and experienced discomfort and swelling of the columella and upper lip. Physical examination revealed mild tenderness on light palpation without any discomfort with upper lip movement. A computed tomography scan of the maxillofacial bones with three-dimensional reconstruction showed a fracture of the anterior nasal spine with obvious leftward displacement, mild-deviation of the caudal aspect of the nasal septum, and no sign of nasal bone fracture. Open reduction and internal fixation was performed with regard to aesthetic and functional concerns, including nasal septum deviation. The postoperative course was uneventful, and healing proceeded normally without complications. Herein, we emphasize the importance of differential diagnosis of isolated anterior nasal spine fractures in patients with midfacial trauma and clinicians' strategic decision-making in treatment modalities.

Purpose: Zygomaticomaxillary complex (ZMC) fracture is one of the most common facial injuries after facial trauma. As ZMC composes major facial buttress, it is a key element of the facial contour. So, when we treat these fractures, the operator should have a concern with the symmetry to restore normal appearance and function. But sometimes, unfavorable results may occur. The aim of this study is to analyze the unsatisfied midfacial contour after ZMC fractures reduction retrospectively and to point out the notandum. Methods: 369 patients, treated for fractures of the ZMC were included in the study. After the operation, such as open reduction and internal fixation (ORIF with titanium or absorbable materials), open reduction, and closed reduction, midfacial contour was evaluated with plain films and 3-dimensional computed tomography. And unfavorable asymmetric midfacial contours were correcterd by secondary correction and re-evaluated. Gross photographs were obtained at outpatient clinic. Results: Total of 38 patients had got a facial asymmetry and among of them 24 patients were treated secondary revisional ORIF operations for correction of unfavorable result of after primary reduction. Two of them had received tertiary operations, three patients had got osteotomy more than after one year and six patients had got minor procedures. The etiology of asymmetry were lateral displaced simple fracture of arch (n=2), lateral displaced comminuted fracture of arch (n=6), comminuted arch fracture combined posterior root fracture (n=9), and communited arch and body fracture (n=12), severely contused soft tissue (n=9). After the manipulations outcomes were acceptable. Conclusion: To prevent the asymmetry in ZMC fracture reduction, complete analysis of fracture, choice of appropriate operation technique, consider soft tissue, and secure of zygoma position are important. Especially, we should be more careful about communited fracture of zygomatic body and lateral displacement, root fracture of zygomatic arch. Because they are commom causes that make facial asymmetry. To get optimal result, ensure the definite bony reduction.

Purpose: Sensory impairment in infraorbital nerve is common symptom following mid-facial fractures. The purpose of this study is to document the incidence of sensory impairment in infraorbital nerve following midfacial fractures and its recovery. Methods: Three hundreds fourteen patients with midfacial fracture were included involving emergence areas of infraorbital nerve. Fractures were classified into zygoma fracture, maxilla fracture, complex comminuted fracture and pure blow out fracture. Neurosensory function was assessed with clinical symptoms and light touch test in infraorbital nerve regions. Patients were followed and sensory function was evaluated immediately, 1, 3 and 6 months after trauma. Results: The total series consisted of 198 zygoma fractures, 19 maxilla fractures, 30 complex comminuted fractures and 67 pure blow out fractures. The incidence of sensory impairment was 60% (63% in zygoma fractures, 84% in maxilla fractures, 93% in complex comminuted fractures, 31% in pure blow out fractures). Persistent sensory impairments were remained in 32% (33% in zygoma fractures, 47% in maxilla fractures, 73% in complex comminuted fractures, 6% in pure blow out fractures) 6 months after trauma. Younger patients had better prognosis than older patients in recovery of infraorbital nerve function ($p$ <0.05, $x^2$-test). Mean recovery time was 11 weeks. Conclusion: The incidence of post-traumatic sensory impairment was different according to fracture types. Age of patients and fracture type were important factors that influence to recovery of sensory impairment. Complex comminuted fracture had poor prognosis, and pure blow out fractures had better prognosis than other fractures.
