본 연구는 서울 경기지역의 치과에 내원한 389명의 환자를 대상으로 교정치료 및 안면성형 수술에 대한 실태를 조사하고자 하였다. 자료수집 후 spss 통계프로그램을 이용하여 분석하였다. 교정치료경험이 있는 환자의 치열만족도가 높게 나타났고(p<0.01), 여자가 남자보다 301-400만원이 적당한 교정치료 비용이라고 높게 인식하고 있었으며(p<0.05) 교정치료 경험이 있는 환자가 19-24개월 이하를 적절한 교정치료 기간으로 인식하고 있었다(p<0.01). 또한 여자가 남자보다 교정치료 검진 필요성(p<0.001), 안면성형수술 경험(p<0.01)이 높게 나타났다. 안면성형수술 희망부위에서는 여자가 눈 수술이(p<0.01), 교정치료 경험이 있는 환자에서는 코 수술이 높게 나타났다(p<0.05). 한편, 여자가 안면 부위 중 눈을 가장 중요하게 인식하고 있었으며(p<0.001), 안면성형 부위 중 양악을 치과에서 해야 한다고 높게 인식하고 있었다(p<0.01). 결론적으로 임상에서 교정치료 및 안면성형을 희망하는 환자 상담 시 성별 및 개인의 요구를 파악하여 진료에 반영하고 특히 안면성형 중 양악수술은 구강의 기능을 고려해야 하므로 치과의료진의 참여가 필수적이라 사료된다.

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 ($7{\times}1.5{\times}1.0cm$) 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, $MTS^{(R)}$) 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.

Nasotracheal intubation is commonly performed under general anesthesia in oral and maxillofacial surgery. For the convenience of surgery, nasal Ring-Adair-Elwyn (RAE) tubes are mainly used. Because the nasal RAE tubes were bent in an "L" shape, the insertion depth was limited. Particularly, it is necessary to accurately determine the appropriate depth of the RAE tubes in children. Several types of nasal RAE tubes are used in the medical market, which vary in material and length. We performed endotracheal intubation using a nasal RAE tube for double-jaw surgery, but air leakage persisted even when the air pressure in the cuff was increased. When checked with a laryngoscope, it was confirmed that the tube was pushed out, and the cuff was caught on the vocal cords, causing air leakage. Since inserting the tube deeply did not solve the problem, replacing it with a nasal RAE tube (Polar^TM, Preformed Tracheal Tube, Smith Medical, Inc., USA) did not cause air leakage; thus, we reported this case.

In the field of orofacial surgery, a red blood cell transfusion (RBCT) is occasionally required during double jaw and oral cancer surgery. However, the question remains whether the effect of RBCT during the perioperative period is beneficial or harmful. The answer to this question remains challenging. In the field of orofacial surgery, transfusion is performed for the purpose of oxygen transfer to hypoxic tissues and plasma volume expansion when there is bleeding. However, there are various risks, such as infectious complications (viral and bacterial), transfusion-related acute lung injury, ABO and non-ABO associated hemolytic transfusion reactions, febrile non-hemolytic transfusion reactions, transfusion associated graft-versus-host disease, transfusion associated circulatory overload, and hypersensitivity transfusion reaction including anaphylaxis and transfusion-related immune-modulation. Many studies and guidelines have suggested RBCT is considered when hemoglobin levels recorded are 7 g/dL for general patients and 8-9 g/dL for patients with cardiovascular disease or hemodynamically unstable patients. However, RBCT is occasionally an essential treatment during surgeries and it is often required in emergency cases. We need to comprehensively consider postoperative bleeding, different clinical situations, the level of intra- and postoperative patient monitoring, and various problems that may arise from a transfusion, in the perspective of patient safety. Since orofacial surgery has an especially high risk of bleeding due to the complex structures involved and the extensive vascular distribution, measures to prevent bleeding should be taken and the conditions for a transfusion should be optimized and appropriate in order to promote patient safety.

Objectives: The requirement for overnight hospital stay should be considered preoperatively according to patient-related factors, type of surgery, and anesthetic management plan. In this study, we aimed to define the major factors that influence consideration of overnight hospital stay in patients undergoing oral and maxillofacial (OMF) surgery in an operating room (OR) of a dental hospital in an outpatient setting. Materials and Methods: The records of patients who underwent oral procedures under general anesthesia between 2014-2017 were reviewed. Results: A total of 821 patients underwent oral procedures under general anesthesia; 631 of them underwent OMF surgery in the OR of a dental hospital, and 174 of these patients were hospitalized for overnight stay. There was no significant difference in the number of patients with comorbidities between the outpatient and hospitalized patient groups (P=0.389). The duration of surgery was longer in the hospitalized patient group (105.25±57.48 vs 189.62±82.03 minutes; P<0.001). Double-jaw (n=15; 310.00±54.21 minutes) and iliac crest grafting surgeries (n=59; 211.86±61.02 minutes) had the longest durations. Patients who underwent iliac crest grafting had the highest rates of hospitalization (79%). The overall recovery period was longer in outpatients (119.40±41.60 vs 149.83±52.04; P<0.001). Conclusion: Duration of surgery was the main determinant in considering whether a patient required overnight hospital stay. However, patients with an American Society of Anesthesiology physical status score <3 may be scheduled for OMF surgery in the OR of a dental hospital in an outpatient setting regardless of duration of surgery if overnight hospital stay is planned or an extended recovery period is provided until patients meet the discharge criteria.

본 연구는 골격성 III 급 부정교합 환자에서 상악골 전방이동수술과 하악골 후방이동수술을 동시에 시행하였을 때 경,연조직 측모 및 연조직 후경의 변화를 관찰하고 경,연조직 변화의 상관성과 그 비율을 산출하여 교정-악교정 수술복합 치료 계획의 수립과 결과의 예측에 이용하고자 하였다. 서울대학교병원 치과진료부 교정과에 내원하여 상, 하악골의 수직적 골격 부조화는 경미하고 전후방적 골격 부조화가 심한 골격성 III급 부정교합으로 진단되어 술전 교정치료를 받고 1990년 7월부터 1995년 4월 중에 Le Fort I 골절단술 또는 Le Fort II 골절단술로 상악골을 전방이동시키는 동시에 시상분할 골절단술로 하악골을 후방이동시킨 성인 환자 25명(남자 13명, 여자 12명) 을 대상으로 수술전,후 측모두부방사선사진을 계측, 분석하여 다음과 같은 결과를 얻었다. 1. 상악골의 전방이동에 따른 상순부 연조직의 수평적 변화는 Stms를 제외하면 상관성이 높았으며 A point의 전방이동에 따라 Sn, SLS, LS 는 각각 $71\%,\;67\%,\;37\%$ 의 비율로 전방이동하였다. 2. 하악골의 후방이동에 따른 하순부 연조직의 수평적 변화는 상관성이 상당히 높았으며 ID, B point, Pog, Gn의 후방이동에 따라 LI, ILS, Pog, Gn 은 각각 $84\%,\;107\%,\;96\%,\;97\%$ 의 비율로 후방이동하였다. 3. 하악골의 후방이동에 따라 SLS, LS, Stm, LI 는 중등도의 상관성을 가지며 하방이동하였다. 4. 경조직의 전후안면고경비율과 연조직의 상,하안면고경 은 수술전후 유의한 차이가 없었으나 수술후 Stm 의 하방이동으로 하순고경에 대한 상순고경의 비율은 유의성있게 증가하였다(p<;0.001). 5. 연조직 후경은 수술후 LI-LIH 에서는 증가하고 LS-LSH 에서는 감소하였으며 LS-LSH 의 수술후 변화량과 수술전 후경은 역상관관계를 나타내었다(p<0.001).
