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 investigate the effect of intraoperative ultrasound-guided nasal bone fracture repair on the clinical outcome of pediatric patients with nasal bone fracture. Methods:A total of 83 patients with nasal bone fracture who underwent prosthesis in our hospital from June 2022 to March 2024 were selected and assigned to control group （endoscopic nasal bone fracture repair） and experimental group （ultrasound-guided nasal bone fracture repair） using random number table method. Both groups were treated with the same nursing measures after surgery. There were 41 cases in the control group and 42 cases in the experimental group. The evaluation parameters of nasal bone fracture, nasal ventilation function, nasal appearance and olfactory function score, postoperative complications and satisfaction were compared between the two groups. Results:The operation time and hospital stay were significantly lower in the experimental group than in the control group （P<0.05）, and secondary repair case （n=0） in the experimental group was significantly less than in the control group （P<0.05）. Compared to preoperative status, the minimum nasal cross-sectional area, nasal volume and total nasal expiratory volume of the two groups increased three months post-operatively, and those in the experimental group were higher （P<0.05）, nasal expiratory and inspiratory resistance, nasal appearance and olfactory disorder scores decreased and those in the experimental group were lower （P<0.05）. The postoperative complications incidence in the experimental group was lower than in the control group （7.14% and 14.63%, respectively, P>0.05）. The overall satisfaction in the experimental group was higher than in the control group（90.48% and 82.93%, respectively, P>0.05）. Conclusion:Ultrasound-guided nasal fracture repair can effectively shorten the operation time, improve the success rate, and promote the postoperative recovery of nasal appearance and nasal function, reduce complications, and enhance the overall satisfaction of children and their families.

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.

Objective: To identify the internal nasal valve (INV) and to evaluate its key parameters in the established 3D models of nasal cavity space via Mimics from CT images, in order to provide evidence for quantitative diagnosis of nasal valve compromise. Methods: A total of 32 Han adults without nasal diseases who underwent maxillofacial CT test in Shanghai Ninth People's Hospital from January 2015 to December 2018 were retrospectively recruited, including 16 males and 16 females, with the age ranged from 20 to 80 years (50% age<50 years old). Maxillofacial CT images were used to create 3D model of nasal cavity space. The INV was identified and the following parameters were measured: the angle between the INV and the nasal bone (θ_INV-B), unilateral cross-sectional area of the INV (A_INV-R, A_INV-L), total cross-sectional area of the INV (A_INV), unilateral height of the INV (H_INV-R, H_INV-L), unilateral nasal valve angle (α_INV-R, α_INV-L), and the sum of nasal valve angle (α_INV). The A_INV in our study was compared with the results of the previously adopted planes (Plane_C, perpendicular to the hard palate and Plane_B, plane perpendicular to the nasal bone). The parameters above were compared among genders, age and race groups. SPSS 26 and GraphPad Prism 9 software were used for statistical analysis and mapping of data. Results: The A_INV in our study was (214.87±52.94) mm², which was significantly less than that of Plane_C (254.97±47.80) mm² and Plane_B (226.07±57.36) mm². The measured parameters were as follows: θ_INV-B was (82.07±7.06)°; A_INV-R was (112.66±31.39) mm²; A_INV-L was (102.21±27.14) mm²; A_INV was (214.87±52.94) mm²; H_INV-R was (24.87±4.62) mm; H_INV-L was (24.35±4.86) mm; α_INV-R was (20.48±2.99)°; α_INV-L was (19.65±3.82)°; α_INV was (40.13±6.24)°. The A_INV-R was larger than A_INV-L (t=2.33, P<0.05); The H_INV, A_INV-R, A_INV-L and A_INV of males were more than those of females (t value was 5.77, 3.21, 2.91 and 3.52, respectively, all P<0.01). The A_INV of the young group (<50 years) was larger than that of the old group (t=2.83, P<0.01); The θ_INV-B was different between the Han people and the Caucasian (t=2.92,P<0.01). The α_INV of the Han people was larger than that of Caucasians (Z=-6.92, P<0.01), but the H_INV was smaller (Z=-3.89, P<0.01). Conclusion: The A_INV carried out in 3D models of nasal cavity space is significantly smaller than that obtained by the previous methods of CT evaluation. INV static parameters differ among genders, age and race groups.

OBJECTIVE: To carry out prenatal diagnosis for a fetus with absent nasal bone by using cytogenetic and molecular techniques. METHODS: Chromosomal karyotyping, single nucleotide polymorphism array (SNP-array) and fluorescence in situ hybridization (FISH) assays were applied for the diagnoses. Peripheral blood samples were also taken from the parents for chromosomal karyotyping and FISH analysis. RESULTS: The fetus was found to have a 46,XX,add(21)(p11.2) karyotype, and SNP-array has revealed a 11.3 Mb duplication at 21q22.12q22.3 (hg19: 36 762 648-48 093 361), which was confirmed by FISH. Both parents were found to be normal by chromosomal karyotyping and FISH analysis. The fetus was ultimately found to have a karyotype of 46,XX,der(21)t(21;21)(p11.2;q22.1), resulting a de novo partial trisomy of 21q22.1. CONCLUSION Combined use of various techniques has enabled accurate prenatal diagnosis and genetic counseling for the fetus.

BACKGROUND: The big data provided by Health Insurance Review and Assessment (HIRA) contains data from nearly all Korean populations enrolled in the National Health Insurance Service. We aimed to identify the incidence of facial fractures and its trends in Korea using this big data from HIRA.METHODS: We used the Korean Standard Classification of Disease and Cause of Death 6, 7 for diagnosis codes. A total of 582,318 patients were included in the final analysis. All statistical analyses were performed using SAS software and SPSS software.RESULTS: The incidence of facial fractures consistently declined, from 107,695 cases in 2011 to 87,306 cases in 2016. The incidence of facial fractures was the highest in June 2011 (n = 26,423) and lowest in January 2014 (n = 10,282). Nasal bone fractures were the most common, followed by orbit and frontal sinus fractures. The percentage of nasal bone fractures declined, whereas those of orbital fractures increased from 2011 to 2016 (P < 0.001). Among orbital fractures, inferior wall fractures were the most common, followed by medial wall fractures. Among mandibular fractures, angle fractures were the most common, followed by condylar process and symphysis fractures. Although it was difficult to predict the most common type of zygomatic and maxilla fractures, their incidence consistently declined since 2011.CONCLUSION: We observed trends in facial fractures in Korea using big data including information for nearly all nations in Korea. Therefore, it is possible to predict the incidence of facial fractures. This study is meaningful in that it is the first study that investigated the incidence of facial fractures by specific type.

Fibrous dysplasia (FD) is a non-malignant bone tumor that typically behaves as a slow and indolent growing mass lesion. We report the case of a female patient presenting with headache and facial deformity and later diagnosed with polyostotic fibrous dysplasia (PFD). A 29-year-old woman visited Mealhada Primary Health Care Unit complaining of headache, nasal congestion, and hyposmia for several weeks. She also presented with facial deformity and painful swelling of the upper left orbit. X-ray imaging revealed a suspicious opacity in the left frontal sinus and a right shift of the nasal septum. Computed tomography and bone scintigraphy later confirmed a tumor involving the ethmoid and frontal bone. The patient was referred to the neurosurgery and otorhinolaryngology departments of a central hospital and the suspected diagnosis of PFD was confirmed. A watchful waiting approach with regular imaging screenings was proposed and accepted by the patient, who is now free of symptoms and more acceptant of the benign condition of her tumor. With this case, we aim to make family physicians more aware of this rare but relevant condition that can be difficult to diagnose. FD is a rare but benign tumor that occurs mainly in adolescents and young adults. Symptoms depend on the location and type of the tumor and include facial deformity, vision changes, nasal congestion, and headache. No clear guidelines exist for its treatment, and options include monitoring the progression of the tumor, in addition to medical or surgical approaches.

The human nervus terminalis (terminal nerve) and the nerves to the vomeronasal organ (VNON) are both associated with the olfactory nerves and are of major interest to embryologists. However, there is still limited knowledge on their topographical anatomy in the nasal septum and on the number and distribution of ganglion cells along and near the cribriform plate of the ethmoid bone. We observed serial or semiserial sections of 30 fetuses at 7–18 weeks (crown rump length [CRL], 25–160 mm). Calretinin and S100 protein staining demonstrated not only the terminal nerve along the anterior edge of the perpendicular lamina of the ethmoid, but also the VNON along the posterior edge of the lamina. The terminal nerve was composed of 1–2 nerve bundles that passed through the anterior end of the cribriform plate, whereas the VNON consisted of 2–3 bundles behind the olfactory nerves. The terminal nerve ran along and crossed the posterior side of the nasal branch of the anterior ethmoidal nerve. Multiple clusters of small ganglion cells were found on the lateral surfaces of the ethmoid's crista galli, which are likely the origin of both the terminal nerve and VNON. The ganglions along the crista galli were ball-like and 15–20 µm in diameter and, ranged from 40–153 in unilateral number according to our counting at 21-µm-interval except for one specimen (480 neurons; CRL, 137 mm). An effect of nerve degeneration with increasing age seemed to be masked by a remarkable individual difference.

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.
