Background: The number of surgical risks recalled by a patient after surgery can be used as a parameter for assessing how well the patient has understood the informed consent process. No study has investigated the usefulness of a self-developed mobile application in the traditional informed consent process in patients with a nasal bone fracture. This study aimed to investigate whether delivery of information, such as surgical risks, through a mobile application is more effective than delivery of information through only verbal means and a paper. Methods: This prospective, randomized study included 60 patients with a nasal bone fracture. The experimental group (n=30) received preoperative explanation with the traditional informed consent process in addition to a mobile application, while the control group (n=30) received preoperative explanation with only the traditional informed consent process. Four weeks after surgery, the number of recalled surgical risks was compared for analysis. The following six surgical risks were explained: pain, bleeding, nasal deformity, numbness, nasal obstruction, and nasal cartilage necrosis. Results: The mean number of recalled surgical risks among all patients was $1.58{\pm}0.56$. The most frequently recalled surgical risk was nasal deformity in both groups. The mean number of recalled surgical risks was $1.72{\pm}0.52$ in the experimental group and $1.49{\pm}0.57$ in the control group. There was a significant association between mobile application use and the mean number of recalled surgical risks (p=0.047). Age, sex, and the level of education were not significantly associated with the mean number of recalled surgical risks. Conclusion: This study found that a mobile application could contribute to the efficient delivery of information during the informed consent process. With further improvement, it could be used in other plastic surgeries and other surgeries, and such an application can potentially be used for explaining risks as well as delivering other types of information.

Background: Trauma is one of the most common causes of enophthalmos, and post-traumatic enophthalmos primarily results from an increased volume of the bony orbit. We achieved good long-term results by simultaneously using an anatomical absorbable implant and iliac bone graft to correct post-traumatic enophthalmos. Methods: From January 2012 to December 2016, we performed operations on seven patients with post-traumatic enophthalmos. In all seven cases, reduction surgery for the initial trauma was performed at our hospital. Hertel exophthalmometry, clinical photography, three-dimensional computed tomography (3D-CT), and orbital volume measurements using software to calculate the specific volume captured on 3D-CT (ITK-SNAP, Insight Toolkit-SNAP) were performed preoperatively and postoperatively. Results: Patients were evaluated based on exophthalmometry, clinical photographs, 3D-CT, and orbital volume measured by the ITK-SNAP program at 5 days and 1 year postoperatively, and all factors improved significantly compared with the preoperative baseline. Complications such as hematoma or extraocular muscle limitation were absent, and the corrected orbital volume was well maintained at the 1-year follow-up visit. Conclusion: We present a method to correct enophthalmos by reconstructing the orbital wall using an anatomical absorbable implant and a simultaneous autologous iliac bone graft. All cases showed satisfactory results for enophthalmos correction. We suggest this method as a good option for the correction of post-traumatic enophthalmos.

Purpose: Blow out fracture resulting from facial trauma is of high frequency among facial bone fractures, and can cause severe complications. So, proper management and close observation after operation are needed. So far, Computed tomography has been the best choice in the evalution following orbit wall reconstruction. However, cost - effectiveness, accessibility to patients and hazard of radiation exposure of computed tomography require supplementary measure for the evaluation following orbit wall reconstruction. This study was performed to describe the effectiveness of ultrasonography in the evalution following orbit wall reconstruction. Methods: A retrospective study was performed on 40 patients who underwent orbit wall reconstruction from June, 2008 to July, 2008. The patients' ages ranged from 13 to 65 years (mean 27.5 years), and this group was compsoed of 27 male and 13 female patients. The follow up period ranged from 2 weeks to 28 weeks (mean 11weeks). Preoperatively, all fractures were diagnosed using computed tomography. Ultrasonography for all cases, and computed tomography for 2 cases were performed for evaluation following orbit wall reconstruction. Results: Reduction of herniated orbital soft tissue and orbit implant was identified by using ultrasonography in 38 cases out of 40 cases. In other cases which we could not identify the orbit implant, computed tomography was performed. Con clusion: Compared to computed tomography, ultrasonography is simple, inexpensive and convenient method. Ultrasonography can be used as supplementary measure to computed tomography in the evaluation following orbit wall reconstruction for elective patients.

목적: 이번 연구 목적은 쇄골 간부 복합 골절에서 21G 환 강선으로 골편 고정 후 재건 금속판을 이용한 내고정술 시 영상학적 및 임상적 결과를 분석하고자 하였다. 대상 및 방법: 2005년에서 2019년 사이에 발생한 쇄골 간부 골절 환자 51명 중 최소한의 연부조직 박리를 통한 21G 환 강선으로 골편 고정 후 재건 금속판을 이용한 내고정술을 시행한 환자 32명과 강선을 사용하지 않고 수술한 환자 19명에 대한 후향적 코호트 연구를 시행하였다. 방사선 검사를 통해 정복 및 골유합을 확인하였고, University of California at Los Angeles (UCLA) 점수와 visual analogue scale (VAS) 통증 점수를 통해 두 군 간의 임상적 결과와 방사선적 결과를 비교하였다. 이를 바탕으로 환 강선을 사용하지 않고 수술한 환자를 대조군으로 설정하여 두 군 간의 골유합의 차이를 비교 분석하였다. 결과: 32명의 환자를 대상으로 평균 65주간의 추시관찰을 하였고, 대조군의 경우 19명의 환자를 대상으로 평균 56주간의 추시 관찰을 하였다. 방사선 검사상 32명 환자 모두에서 해부학적 정복 및 골유합을 확인하였다. UCLA 점수는 평균 32.38점, 대조군 33.11점(p=0.395), VAS 점수는 평균 1.00점, 대조군 0.84점으로(p=0.668) 통계적으로 의미 있는 차이가 없었다. 대조군과 비교하였을 때 골유합 시기의 차이에 통계적 유의성이 있었으나(p=0.015) 다른 변수를 통제하였을 때는 통계적으로 유의성이 없음을 알 수 있었다(p=0.107). 결론: 전위성 쇄골 간부 복합 골절에 대해 21G 강선 및 재건 금속판을 이용한 내고정술은 정확한 해부학적 정복과 견고한 내고정을 유지할 수 있었고, 환 강선을 통해 작은 골편도 고정할 수 있었다. 방사선 및 임상 결과에서 만족스러운 결과를 얻었기에 재건 금속판 및 21G 강선을 이용한 내고정술이 수술적 치료의 좋은 선택이 될 수 있다고 생각된다.

Purpose: The majority of nasal fractures have been treated by closed reduction. And they were manipulated under local anesthesia or general anesthesia. Under the local anesthesia, patients can feel the pain and fear, so general anesthesia through the endotracheal intubation became popularized recently to treat the nasal fracture. But it has still the drawbacks of postanesthetic complication. Therefore, under the mask ventilation anesthesia using oral airway, we tried to manipulate the nasal fracture. Methods: From July 2007 to November 2007, we worked with fifty patients that were manipulated the nasal fracture. Fifty patients were divided into two groups, general anesthesia with the endotracheal intubation group(n=25) and the mask ventilation using oral airway group(n=25). We checked up the anesthesia time, postanesthetic complication, postoperative aesthetic & functional problem of nose in two groups. Results: In total operation time and sore throat frequency among the postoperative anesthetic complications, there was statistically significant difference between the mask ventilation group and the endotracheal intubation group(p<0.05). But there was no difference statistically in nausea frequency(p>0.05). And no patients complained of postoperative nasal complication such as septal deviation, septal perforation, nasal obstruction and hump nose in two groups. Conclusion: Through the mask ventilation using oral airway, we could reach satisfactory results in the anesthetic time and postanesthetic complication.

Major maxillofacial bone injury itself can be life threatening from both cardiovascular point of view, as well as airway obstruction. Significant hemorrhage from facial fracture is an uncommon occurrence, and there is little in the literature to guide the management of these patients. We report a 73-year-old male driver who was transported to our hospital after a motor vehicle collision. The patient was hypotensive and tachycardic at presentation and required active fluid resuscitation and transfusion. The patient was intubated to protect the airway. All external attempts to control the bleeding, from packing to fracture reduction, were unsuccessful. Emergency angiogram revealed the bleeding to originate from terminal branches of the sphenopalatine artery, which were embolized. This was associated with cessation of bleeding and stabilization of vital signs. Despite the age and severity of injury, the patient recovered well and was discharged home at 3 months with full employment. In facial trauma patients with intractable bleeding, transcatheter arterial embolization should be considered early in the course of management to decrease mortality rate.

현대 사회에서 외상의 특성은 다발성 손상이 빈발하는 것이며 상악골절시 생명을 위협하는 다발성 전신손상이 동반되면 수술이 지연되어 골절부의 지연된 부정유합을 보일 수 있다. 또한 골절된 양상에 따라서는 관혈적 정복술의 적용여부가 고려되는데 특히 골절편의 분쇄가 심하면 수술시 골절부위의 이개 후 정상위치로의 이동이 어렵고 설사 골절편의 이동이 이루어졌다고 하여도 정상위치로의 고정이 용이하지 않을 뿐만 아니라 분쇄골절편의 상실량이 많아지면 골이식까지 시행해야 하는 등 외과적이술식의 적용에 많은 난관이 예상된다. 따라서 상악골절 후 통상 6주일 간의 시간경과가 없다면 오히려 상악골절편의 이동방향을 예측하여, 전방견인용 headgear 또는 headcap 을 사용한 교정적인 치료를 시도함이 바람직할 수도 있다. 더우기 reverse headgear를 이용한 치료법은 골절된 경우가 아니더라도 상악골의 전방이동에 유용함이 실험적으로나 임상적으로 입증된 만큼 이를 상악골절후 후퇴된 상악골의 전방견인에 적용할 경우 교정치료의 최대장애인 cortical bone의 연속성이 골절로 인해 끊어지고 섬유성 유착상태로 남게되어 교정력의 효과가 치아이동 뿐만 아니라 골편의 이동에 매우 유익하리라 사료된다. 이에 저자는 상악골적이 분쇄양상인 한 환자에서 headgear와 headcap을 이용한 교정치료법을 5개월간 적용해 양호한 결과를 얻었고, 골절양상이 분쇄형이 아닌 증례에서는 외상후 5주간 경과 되었지만 관혈적 정복술을 시행하여 정상교합을 회복했으며, 심한 두부 손상으로 6개월만에 의식 회복을 한 LeFort I, II, III, 환자에서는 두부방사선 계측학적 분석, 교합기 상에서의 모형분석, 전산화 단층촬영 검사 등을 시행한 후 새로운 골면에다 LeFort I -osteotomy with iliac bone graft를 시행해 정상교합 및 안모추형을 개선시켰기에 이를 보고한다.

Purpose: Several authors reported about the post - traumatic nasal aesthetic complications. However, the study for functional or intra - nasal complications has been reported not enough. The aim of this study is to observe the incidence of intranasal synechia. Methods: We reviewed the data from 401 consecutive patients with nasal bone fracture from september 2006 to December 2007. We enforced evaluation with preoperative CT in all patients but postoperative CT within complicated patients. We classified the nasal bone fracture according to the anatomy and severity of fracture. Type I is nasal tip fracture(15%, n = 59), Type II is simple lateral without septal injury(38%, n = 152), Type III is simple lateral with septal injury(23%, n = 92), Type IV is closed comminuted(20%, n = 82), Type V is open comminuted or complicated(4%, n = 16). We studied 98 patients with nasal bone fracture who had postoperative symptoms or undergone postoperative endoscopic evaluation. And then we evaluated the postoperative endoscopic finding and nasal synechal formation after operation. Results: The incidence of intranasal synechiae was 15%(n = 62). According to the endoscopic findings, the incidence of intranasal synechiae was 10%(n = 6) in Type I, 8%(n = 12) in Type II, 16%(n = 15) in Type III, 24%(n = 20) in Type IV, and 56%(n = 9) in Type V. Additionally, the incidence of subjective nasal obstruction and olfactory dysfunction is 18%(n = 72) and 13%(n = 51). But the incidence of symptomatic synechiae of nasal obstruction and olfactory dysfunction is 92%(57/62) and 55%(34/62). Conclusion: We identified relatively high prevalence of nasal obstruction and olfactory dysfunction in nasal synechiae. Based on the results of this study, intranasal synechiae really caused airway obstruction(92%). Our data showed significant relationship between intranasal synechiae and severity of the fracture, because of increasing mucosal handling and destructive closed reductional procedures. First of all, education of delicate procedure regarding this subject should be empathized accordingly.
