Background: After closed reduction, patients are sometimes concerned that their external nasal shapes have changed. The aim of this study was to investigate and explain changes in nasal shape after surgery through objective photogrammetric anthropometry measurements taken through three-dimensional (3D) reformed computed tomography (CT) images. Methods: Our study included 100 Korean patients who underwent closed reduction of isolated nasal bone fracture from January 2016 to June 2017. Using the ruler tool in Adobe Photoshop CS3, we measured preoperative and postoperative nasal base heights, long nostril axis lengths, both nasal alar angles, and amount of nasal deviation through the 3D reformation of soft tissue via CT scans. We then compared the dimension of nose. Results: The amount of postoperative correction for nasal base height was 1.192 mm. The differences in nostril length between each side were found to be 0.333 mm preoperatively and 0.323 mm postoperatively. The differences in the nasal alar angle between each side was $1.382^{\circ}$ preoperatively and $1.043^{\circ}$ postoperatively. The amount of nasal deviation was found to be 5.248 mm preoperatively and 1.024 mm in postoperatively. Conclusion: After the reduction of nasal bone fractures, changes in nasal dimensions were noticeable in terms of nasal deviation but less significant in nasal tips, except for changes in nasal alar angles, which were notable.

The initial instance of isolated unilateral temporalis muscle hypertrophy (IUTMH) was reported in 1990. Since then, only few cases have been documented. The cause of this condition remains ambiguous; however, it is presumed to be linked to compensatory and stress-induced hypertrophy. We introduce a rare case of the diagnosis and treatment of IUTMH. A 39-year-old woman presented with a steadily enlarging pain-free swelling on the left side of her face, first noticed a month ago. Apart from a hyperthyroidism medication regimen her medical history was unremarkable. She had no history of temporomandibular joint disease, bruxism, surgery, or trauma. However, she complained of having been under substantial stress lately. Contrast-enhanced magnetic resonance imaging revealed asymmetric temporalis muscle hypertrophy. The treatment plan consisted of administering type A botulinum toxin injections into left temporalis muscle, supplemented by lifestyle changes and relaxation techniques. At a follow-up visit 9 months after the injections, the muscle contour was normalized both in physical and in radiologic examinations. While further supportive evidence is needed, it can be anticipated that cosmetic treatment with botulinum toxin, rather than surgical interventions, will become the standard treatment of IUTMH.

Craniosynostosis is a congenital anomaly in which cranial sutures close prematurely and restrict skull growth. In this paper, the case of two siblings, a male and a female, who were both diagnosed as craniosynostosis is reported. They underwent corrective osteotomy for cranial vault remodeling. A 22-month-old female infant who was brought to the department of plastic and reconstructive surgery of the authors' hospital was diagnosed with plagiocephaly. At the same time, her 7-month-old brother was diagnosed with brachycephaly. In the case of the female infant, corrective coronal osteotomy and supraorbital bar advancement were performed. Her brother underwent frontal advancement osteotomy using Tessier's tongue in the groove procedure. After the correction of the craniosynostosis, the two patients recovered in several days later, and the results were good in both cases cosmetically and functionally. They showed normal head circumference increasing curves and no symptom of functional disorder in their last follow-up. Isolated or nonsyndromic craniosynostosis is sporadic but mostly autosomal dominant. This paper presents a case of craniosynostosis with a genetic tendency; and although it occurred between siblings, the affected lesions differed. Thus, appropriate diagnosis and management in patients are needed.

Background: Many authors have evaluated the post-reduction result of nasal bone fracture through patient satisfaction or postoperative complications. However, these results are limited because they are subjective. The aim of this study was to correlate an objective operation result with patient satisfaction and postoperative complications according to the type of nasal bone fractures. Methods: Our study included 313 patients who had isolated nasal bone fractures and had undergone a closed reduction. Postoperative outcomes were evaluated objectively using computed tomographic (CT) images, while patient satisfaction was evaluated one month after the operation. The correlation of the operation result with patient satisfaction was then evaluated. Results: The correlation between the operation result and patient satisfaction was highest for the lateral impact group type I (LI) type of fracture and lowest for the comminuted fracture group (C) type of fracture. However, there were no statistically significant differences in correlation between the overall result and patient satisfaction by fracture type. The complication rate of lateral impact group type II (LII), C, and frontal impact group type I (FI) fractures were statistically significantly higher than that of frontal impact group type II (FII) and LI fractures. There were no statistically significant relationships between the prevalence of complications and septal fracture or deviation according to the fracture type. In the total group, however, there was a statistically significant difference in complication rate by septal fracture. Conclusion: We found that the CT outcomes correlated with patient satisfaction. The complication rate of LII, C, and FI fractures were statistically significantly higher than that of FII and LI fractures. Septal fracture/deviation increased the postoperative complication in the total group.

Background: The aim of our retrospective study is to evaluate the management of isolated orbital floor fractures considering the clinical, functional and aesthetic results according to the surgical approach and the type of materials used. Methods: Retrospectively, clinical, radiological, surgical, and ophthalmological data from 79 patients were collected from January 2010 to December 2016. Furthermore, included patients were interrogated on functional and aesthetic satisfaction. Results: The main causes of trauma were physical aggression followed by accidents. The median time between trauma and surgery was 4 days. The most common surgical approaches were the subciliary and the transconjunctival ones. Alloplastic materials were used in 75 patients. In two patients, we used a combination of two grafts. Patients experienced minor immediate complications. On follow-ups, none of our patients suffered from ocular movement restrictions. Patients treated by subciliary approach had higher risk of retractile scaring compared to other surgical approaches. In our study, patients agreed to complete a questionnaire assessing functional and aesthetic outcomes with a high satisfaction score. No association between the implant material used and the results has been assessed. Conclusion: This study describes the results of orbital floor reconstructions. Despite a variety of materials used and surgical approaches performed, we believe that the transconjunctival approach is the most suitable option with a high satisfaction score.

Background: The incidence of blow out fractures is increasing and the techniques of diagnosis and treatment have been recently evolving. Despite its clinical significance, there has been no study on orbital inferiomedial blow out fractures. Therefore, this study was designed to investigate the clinical significance of treatment of orbital inferiomedial blow out fractures. Methods: A retrospective review of fifty-seven patients who could be followed up for at least 1 year after surgical reconstruction of pure inferiomedial blow out fracture was undertaken. The transconjunctival approach was performed in all cases. The onlay technique was used in 32 patients and the inlay/sheet method was used in 25 patients. We evaluated the clinical outcomes using the chi-square test. Results: In the group using the onlay technique, postoperative diplopia and enophthalmos were observed in 14 cases and 3 cases, respectively. Of these, 5 cases and 3 cases lasted for more than 6 months, respectively. In the group using the inlay/sheet method, postoperative diplopia was observed in 9 cases, but there were no cases of enophthalmos. Among the 9 diplopia cases, 4 lasted for more than 6 months. Conclusion: Postoperative diplopia and enophthalmos were increased after treatment of inferiomedial blow out fractures compared to isolated medial (0.6%, 0.3%) or inferior (1.8%, 0.6%) blow out fractures. Therefore, careful dissection is necessary not to injure the inferior oblique muscle to decrease the incidence of postoperative diplopia. Moreover, the inlay/sheet method is an effective option for reconstruction of inferiomedial blow out fractures.

Background: Orbital resorbable mesh plates are adequate to use for isolated floor and medial wall fractures with an intact bony buttress, but are not recommended to use for large orbital wall fractures that need load bearing support. The author previously reported an orbital wall restoring surgery that restored the orbital floor to its prior position through the transnasal approach and maintained temporary extraorbital support with a balloon in the maxillary sinus. Extraorbital support could reduce the load applied on the orbital implants in orbital wall restoring surgery and the use of resorbable implants was considered appropriate for the author's orbital wall restoring technique. Methods: A retrospective review was conducted of 31 patients with pure unilateral orbital floor fractures between May 2014 and May 2018. The patients underwent transnasal restoration of the orbital floor through insertion of a resorbable mesh plate and maintenance of temporary balloon support. The surgical results were evaluated by the Hertel scale and a comparison of preoperative and postoperative orbital volume ratio (OVR) values. Results: The OVR decreased significantly, by an average of 6.01% (p<0.05) and the preoperative and postoperative Hertel scale measurements decreased by an average of 0.34 mm with statistical significance (p<0.05). No complications such as buckling or sagging of the implant occurred among the 31 patients. Conclusion: The use of resorbable mesh plate in orbital floor restoration surgery is an effective and safe technique that can reduce implant deformation or complications deriving from the residual permanent implant.

Background: There have been many reports of nasal bone fractures in adults, but there are few clinical reports of them in adolescents, although adolescence is the main growth period of the nasal bone. In addition, previous studies have tended to classify and describe child and adolescent nasal fractures in the same category. The aim of this study was to identify the clinical aspects of nasal fractures in adolescents, and to evaluate the characteristics of nasal fractures in the growth period. Methods: Our institution's database was reviewed to extract data on adolescent patients between the age of 13 to 18 who had isolated nasal bone fractures from March 2012 to February 2020. The study excluded patients with other facial fractures, previous facial fractures, or congenital deformities. Results: This study included 243 boys and 26 girls. Interpersonal violence and sports-related accidents accounted for 85 and 79 cases, respectively. There were 128 frontal impact injuries and 132 lateral impact injuries, and 97 patients had accompanying septal fractures. An accompanying septal fracture was present in 36.06% of all patients, but in 51.20% of those who underwent surgery. Conclusion: The prevalence of adolescent nasal fractures was significantly higher in boys, to a greater extent than observed for pediatric or adult fractures. The main causes of fractures were interpersonal violence and sports-related accidents. An explanation for these results is that adolescent boys are more prone to have violent accidents or companionship with active sports than other age or sex groups, leading to substantially more fractures.

Background: Frontal sinus fractures are relatively rare. Their surgical management significantly differs depending on whether the posterior wall is invaded and the clinical features vary. A bicoronal incision or endoscopic approach can be used. However, the minimally invasive approach has been attracting attention, leading us to introduce a simple and effective surgical method using multiple-threaded Kirschner wires. Methods: All patients had isolated anterior wall fractures without nasofrontal duct impairment. The depth from the skin to the posterior wall was measured using computed tomography to prevent injury. The edge of the bone segment on the skin was marked, a threaded Kirschner wire was inserted into the center of the bone segment, and multiple Kirschner wires were gently reduced simultaneously. Results: Surgery was performed on 11 patients. Among them, seven patients required additional support for appropriate fracture reduction. Therefore, a periosteal elevator was used as an adjunct through a small sub-brow incision because the reduction was incomplete with the Kirschner wire alone. The reduction results were confirmed using facial bone computed tomography 1 to 3 days postoperatively. The follow-up period was 3 to 12 months. Conclusion: The patients had no complications and were satisfied with the surgical results. Here we demonstrated an easy and successful procedure to reduce a pure anterior wall frontal sinus fracture via non-invasive threaded Kirschner wire reduction.

목 적 : 중이염은 나이 어린 소아에 많이 발생하며 항생제가 흔히 처방되는 질환이 최근에는 세균의 항생제에 대한 내성률이 증가되고 있어 중이염 환자에서 항생제 선택이 신중해야 함이 심도 있게 거론되고 있다. 국내에서는 중이염에 대한 체계적인 연구가 부진한 상태이며 이에 저자들은 중이염의 원인 및 항생제 감수성을 파악하기 위하여 후향적으로 본 연구를 실시하였다. 방 법 : 1994년 7월부터 1999년 6월까지 한양대학교병원 소아과 및 이비인후과에서 이루를 동반한 중이염으로 진단 받은 15세 미만의 소아 중 이루 배양 검사 결과 세균이 분리된 65명을 대상으로 의무 기록을 후향적으로 분석하였다. 결 과 : 총 65명의 환아 중 남자 37명(57%), 여자 28명(43%)이었으며 평균 나이는 2.9세로 나이가 어릴수록 많아 1세 미만 27명(41.5%), 1~3세 24명(36.9%)이었으며, 3세 이하가 78%를 차지하였다. 분리된 균주의 분포는 Staphylococcus aureus 32명(49.2%), Streptococcus pneumoniae 19명(29.2%), Haemophilus influenzae 9명(13.8%), Streptococcus oralis 3명(4.6%), Moraxella catarrhalis 1명(1.5%) 등이었다. 구순열/구개열을 동반한 9명(14%)의 환아에서 분리된 균주의 분포는 구순열/구개열을 동반하지 않은 환아에서와 유사하였다. 분리된 S. aureus의 항생제 내성률은, erythromycin, imipenem, cephalothin, clindamycin에 90% 이상, oxacillin 86.2%, chloramphenicol 25%, trimethoprim-sulfamethoxazole(TMP-SMX) 12.5%, vancomycin과 teicoplanin에 0%이었다. S. pneumoniae의 내성률은 penicillin에 71.4%, erythromycin, tetracycline 및 trimethoprim-sulfamethoxazole(TMP-SMX) 60% 이상, chloramphenicol 7.1%, vancomycin, teicoplanin, ciprofloxacin에는 0%이었다. H. influenzae의 내성률은 ampicillin, TMP-SMX에 각각 55.5%이었으나 chlroramphenicol, ceftriaxone, aztreonam, imipenem, ciprofloxacin에는 모두 감수성이 있었다. 결 론 : 본 연구조사 결과 이루를 동반한 중이염의 원인은 S. aureus, S. pneumoniae 및 H. influenzae로 판명되었으며, 분리된 균주들의 높은 항생제 내성률은 중이염의 치료를 위한 항생제 선택에 반영되어야 할 것으로 사료된다. 향후 전향적인 고막천자를 이용한 연구조사가 이루어져 급성 중이염을 더 정확히 파악할 수 있어야겠다.
