Objective:To compare the outcomes of simultaneous versus staged nasal bone reduction and septoplasty in the treatment of traumatic nasal bone fractures with associated septal fractures. Methods:Patients with traumatic nasal bone fractures, with or without septal fractures, were recruited from two hospitals and divided into three groups. Group A underwent simultaneous nasal bone reduction and septoplasty, Group B underwent staged nasal bone reduction and septoplasty, and Group C underwent nasal bone reduction only. Nasal appearance scores and nasal congestion Visual Analogue Scale （VAS） scores were measured preoperatively, at 2 weeks postoperatively, and at 3 months postoperatively. For Group B, scores were also recorded at 2 weeks and 3 months after the second-stage surgery. Differences were analyzed using statistical software. Results:Two weeks post-surgery, the nasal appearance scores significantly decreased in all three groups compared to preoperative scores （P< 0.01）, with no statistically significant differences between the groups （P= 0.43, 0.71, 0.58）. In Group A, the VAS score for nasal congestion decreased significantly following simultaneous surgery （P<0.01）. In Group B, there were no significant differences in nasal congestion VAS scores between pre-surgery and post-first-stage, nor between three months post-first-stage and two weeks post-first-stage （P= 0.61, 0.13）. However, the VAS scores significantly decreased after the second-stage surgery compared to pre-surgery, and three months post-second-stage surgery compared to three months post-first-stage surgery （P<0.01）. The VAS scores for nasal congestion at two weeks post-surgery in Group A were lower than those in Group B after the first-stage surgery （P<0.01）. The incidence rates of nasal adhesions post-surgery in Groups A, B, and C were 0%, 6.9%, and 4.3%, respectively. Conclusion:For traumatic nasal bone fractures with associated septal fractures, performing simultaneous nasal bone reduction and septoplasty under general anesthesia using endoscopy is more time-efficient compared to staged surgery, and it results in a lower occurrence rate of post-surgical nasal adhesions.

Objective:To explore the clinical effects of two kinds of nasal bone reductors used for shortened and displaced overlapping external nasal fracture reduction under nasal endoscopy and the impact on ventilation function. Methods:From January 2020 to February 2022, 82 patients with shortened and displaced overlapping external nasal fractures diagnosed and treated in the Department of Otolaryngology, the Second People's Hospital of Hefei were collected as the study subjects. The patients were divided into control group（41 cases） and observation group（41 cases） by random number table method. Both groups underwent closed reduction under nasal endoscopy. The control group was treated with traditional straight nasal bone reductor, and the observation group was treated with gun-shaped hook type nasal bone reductor. The success rate of reduction, follow-up rate, clinical effect, and complications were compared between the two groups. The visual analogue scale（VAS） was used to evaluate the aesthetic effect and functional recovery. Rhinomanometry and acoustic rhinometry were used to evaluate nasal ventilation function. Results:The success rate of one-time reduction in the observation group was significantly higher than that in the control group, and the nasal reduction adaptation time was shorter than that in the control group（P<0.05）. There was no significant difference in the follow-up rate of 95.12% and 92.68% between the two groups. The success rate of one-time reduction in observation group was significantly higher than that in the control group, and the adaptation time for nasal reduction in observation group was shorter than that in the control group（P<0.05）. There was no significant difference in the follow-up rate of 95.12% and 92.68% between the two groups in six months after surgery. the total clinical effective rate in observation group was higher than that in the control group（94.87% vs 76.32%, P<0.05）. After surgery, the scores of nasal aesthetics, nasal congestion and olfactory function in both groups were significantly lower compared with the preoperative scores. All the scores in the observed group were lower than that in the control group（P<0.05）. After surgery, there were significant increases in the minimum cross-sectional area of nasal cavity, volume of nasal cavity and total nasal expiratory volume in both groups. Above indicators in observation group were significantly greater than that in control group. The nasal exhalation and inhalation resistance was significantly lower than that before operation, and the resistance in observation group was significantly lower than that in control group（P<0.05）. The total incidence of complications was lower than that in observation group（P<0.05）. Conclusion:The application of gun-shaped hook-type nasal bone reductor in patients with shortened and displaced overlapping external nasal fractures has better success rate of one-time reduction, adaptation time of nasal reduction and treatment outcome. Moreover, it has more advantages in aesthetic effect of nasal appearance, nasal ventilation function and reduction of complications.

BACKGROUND: Prophylactic antibiotic administration after surgery for a nasal bone fracture is performed due to concerns about infection-related complications, such as, toxic shock syndrome. To evaluate the validity and efficacy of antibiotic use, we compared the results obtained and the bacterial profiles of nasal packing materials in patients that underwent closed reduction for a nasal bone fracture with or without prophylactic antibiotic administration. METHODS: Thirty consecutive patients with a nasal bone fracture, but without an open wound, that underwent closed reduction during March to August 2017 were included in the present study. Fifteen of these 30 patients were randomly assigned to a control group, members of were administered postoperative intravenous antibiotics once at the day of surgery and then oral antibiotics for 4 days. The other 15 patients were assigned to an experimental group and not administered any antibiotic postoperatively. Antibiotic ointment was not applied to nasal packing in either group. Nasal packing was removed on postoperative day 4 in all cases. Removed nasal gauze packings were culture tested and strains identified in the two groups were compared. RESULTS: Bacterial strain types cultured from packings were similar in the experimental and control groups and no patient showed signs of clinically significant infection. CONCLUSION: The findings of this study suggest postoperative prophylactic antibiotic use is not clinically required after closed reduction of a nasal bone fracture. Furthermore, the non-use of postoperative antibiotics is biologically beneficial, as it reduces the occurrence of resistant strains and medical costs, and is more convenient for patients.

BACKGROUND: Nasal bone fractures occur frequently because the nasal bone is located at the forefront of the face. The goal of this study was to examine the cause, change in severity, change in incidence, and demographics of nasal bone fracture according to today's lifestyle. METHODS: A total of 2,092 patients diagnosed as having nasal bone fractures at our department between 2002 and 2017 were included in this study. We retrospectively examined patients' medical records to extract information regarding age, sex, cause of injury, combined facial bone fractures, and related injuries such as skull base fracture, spinal cord injury, brain hemorrhage, and other bone fractures. Fracture severity was classified by nasal bone fracture type. RESULTS: No statistically significant difference was found in annual number of patients treated for nasal bone fracture. The proportion of patients who underwent closed reduction was significantly decreased over time for those with nasal bone fractures caused by traffic accidents. However, it was not significantly changed for those with nasal bone fractures due to other causes. The number of patients with combined facial bone fractures increased over time. Incidences of severe nasal bone fracture also increased over time. CONCLUSION: The study suggested that there is a decrease in the frequency and increase in the severity of nasal bone fracture due to traffic accident. Many protective devices prevent nasal bone fractures caused by a small amount of external force; however, these devices are not effective against higher amounts of external force. This study highlights the importance of preoperative thorough evaluation to manage patients with nasal bone fractures due to traffic accident.

Pentastomiasis, a zoonotic parasite infection, is typically found in the respiratory tract and viscera of the host, including humans. Here, we report for the first time an extremely rare case of intraosseous pentastomiasis in the human maxilla suffering from medication related osteonecrosis of the jaw (MRONJ). A 55-year-old male had continuously visited the hospital for MRONJ which had primarily developed after bisphosphonate and anti-neoplastic administration for previous bone metastasis of medullary thyroid cancer. Pain, bone exposure, and pus discharge in the right mandible and left maxilla were seen. Osteolysis with maxillary cortical bone perforation at the left buccal vestibule, palate, nasal cavity, and maxillary sinus was observed by radiologic images. A biopsy was done at the left maxilla and through pathological evaluation, a parasite with features of pentastome was revealed within the necrotic bone tissue. Further history taking and laboratory evaluation was done. The parasite was suspected to be infected through maxillary open wounds caused by MRONJ. Awareness of intraosseous pentastomiasis should be emphasized not to be missed behind the MRONJ. Proper evaluation and interpretation for past medical history may lead to correct differential diagnosis and therapeutic intervention for parasite infections.

OBJECTIVES: Submental intubation has been advocated as an alternative to classical tracheostomy for certain indicated panfacial trauma surgeries. Surgeons should have various options for airway management in maxillofacial trauma patients. Most maxillofacial injuries involve occlusal derangements, which might require intraoperative occlusal corrections; hence, orotracheal intubation is not ideal. Maxillofacial surgeons generally prefer nasotracheal intubation; however, in cases with concomitant skull base fracture or nasal bone fracture, nasotracheal intubation might not be suitable; in these situations, tracheostomy is typically performed. However, the possible complications of tracheostomy are well known. Due to trauma situations and to avoid the complications of tracheostomy, submental intubation would be an ideal alternative procedure in selected maxillofacial trauma surgery patients. This study aimed to evaluate the safety and usefulness of a submental intubation technique for panfacial trauma surgery. Moreover, we intended to share our experience of submental intubation and to recommend this simple, safe procedure for certain panfacial trauma surgeries. MATERIALS AND METHODS: In five panfacial trauma patients, we performed submental intubation for airway management; the mean time required for the procedure was only eight minutes. RESULTS: We were able to execute this procedure safely in a short time without any intraoperative or postoperative complications. CONCLUSION: Submental intubation is a safe and simple technique for airway management in indicated panfacial trauma surgery patients.

OBJECTIVES: To explore the characteristics of nasal bone fracture caused by blunt instrument, including the fracture types, the fracture repair, and the difference of manifestations between X-ray and CT. To provide reference for the identification. METHODS: The information of basic situation, fracture site, injury manner, diagnosis method, expert opinion of 95 adult nasal fracture cases caused by blunt object, which occurred in Gutian county of Fujian province from January 1999 to December 2013, were analyzed by descriptive statistics. The identification conclusions of different injuries were compared according to new and old standards as well. RESULTS: There were total 95 adults including 87 male and 8 female. The fracture site and quantity have significant correlation with the nasal bone anatomical relations and the direction and size of the force. Compound fracture was most common. The fracture that could not be determined by X-ray could be clearly diagnosed by CT examination. According to new and old standards, different fracture types have different identification conclusions. CONCLUSIONS There are gender differences in nasal bone fracture cases. Larger external force is easy to cause compound fracture. CT examination is significantly better than X-ray examination.

OBJECTIVES: The facial bones are the most noticeable area in the human body, and facial injuries can cause significant functional, aesthetic, and psychological complications. Continuous study of the patterns of facial bone fractures and changes in trends is helpful in the prevention and treatment of maxillofacial fractures. The purpose of the current clinico-statistical study is to investigate the pattern of facial fractures over a 4-year period. MATERIALS AND METHODS: A retrospective analysis of 1,824 fracture sites was carried out in 1,284 patients admitted to SMG-SNU Boramae Medical Center for facial bone fracture from January 2010 to December 2013. We evaluated the distributions of age/gender/season, fracture site, cause of injury, duration from injury to treatment, hospitalization period, and postoperative complications. RESULTS: The ratio of men to women was 3.2:1. Most fractures occurred in individuals aged between teens to 40s and were most prevalent at the middle and end of the month. Fractures occurred in the nasal bone (65.0%), orbital wall (29.2%), maxillary wall (15.3%), zygomatic arch (13.2%), zygomaticomaxillary complex (9.8%), mandibular symphysis (6.5%), mandibular angle (5.9%), mandibular condyle (4.9%), and mandibular body (1.9%). The most common etiologies were fall (32.5%) and assault (26.0%). The average duration of injury to treatment was 6 days, and the average hospitalization period was 5 days. Eighteen postoperative complications were observed in 17 patients, mainly infection and malocclusion in the mandible. CONCLUSION: This study reflects the tendency for trauma in the Seoul metropolitan region because it analyzes all facial fracture patients who visited our hospital regardless of the specific department. Distinctively, in this study, midfacial fractures had a much higher incidence than mandible fractures.

The bony naso-orbital-ethmoid (NOE) complex is a 3-dimensional delicate anatomic structure. Damages to this region may result in severe facial dysfunction and malformation. The management and optimal surgical treatment strategies of NOE fractures remain controversial. For a patient with NOE trauma, doctors should perform comprehensive clinical examination and radiographic analysis to assess the type and extent of fracture. The results of assessment will assist doctors to make a patientspecific program for the sake of reducing post-operation complications and restoring normal appearance and function as much as possible. This review focuses on the advancement of management of NOE fractures including symptoms, classifications, diagnosis, approaches, treatment and new techniques in this field.

OBJECTIVE: To evaluate the age, sex, etiology, diagnosis and treatment time of nasal bone fractures. METHOD: Clinical data of 202 cases with nasal bone fractures treated in the hospital were retrospectively analysed. RESULT: A total of 202 cases,163 men (80. 7%) and 39 women (19. 3%). Fifty-two patients had a relationship with alcohol consumption, and all of them were males. The most frequent reasons of the injury were fight 46. 5% (94 cases) followed by falling-down 21. 3% (43 cases), traffic accidents 19. 3% (39 cases), works related 6. 5% (13 cases), sport injuries 5. 9% (12 cases) and others 0. 5% (1 cases). Patients distribution in seasons were: spring 54 cases (26.7%), summer 42 cases (20.8%), autumn 58 cases (28.7%), winter 48 cases (23. 8%). Diagnosis of nasal bone fractures were made positively by x-ray films in 79. 7% of cases, but 100% by CT. Positive predictive value of CT was superior to that of X-ray films in the diagnosis of nasal bone fracture. CONCLUSION High morbidity of nasal bone fracture was seen in the age group of 20-29 years, and predominantly in male. Fight was found to be the main etiologic factor. We think that CT is necessary for diagnosing nasal bone fracture.
