Purpose: The nasal bone fracture is known as the most common facial fracture. Several authors reported the classification of nasal bone fracture. Stranc classified the type of nasal fractures based on a pattern of impaction and level of injuries. Stranc classification proposed here is based on careful clinical observation and relates to both treatment and prognosis. The aim of this study is to determine any predictive value to the preoperative classification of nasal fracture, using the description by Stranc and Robertson. Methods: We reviewed 310 patients with nasal bone fracture treated at our hospital for last two years. Results: Lateral impact type of nasal bone fracture predominated more than frontal impact in the ratio of 2.3:1. The most common type of Stranc classification was lateral impact plane I(48.4%). Male predominated more than female in the ratio of 3:1. The most frequent age group was first decade(27.1%), second decade in frontal impact(30.5%), first decade in lateral impact (30.7%). The most common etiology was violence (31.3%) followed by slip down(21.3%), and traffic accident(18.1 %).The most common associated fracture was orbital(22.9%) followed by zygoma(10%), and maxilla (6.1%). The most common complication was septal deviation(20.0%) in frontal impact, and nasal deformity (26.0%) in lateral impact. The incidence of nasal deformity in lateral impact(26.0%) was more higher than frontal impact(15.8%) Conclusion: By assessing the pathomechanics and resultant degree of injury to the nasal skeleton, a better understanding of the treatment plan and prognosis was obtained. Using this information, satisfactory informed patient consent can be obtained.
Purpose: Although nasal fractures are often discussed as minor injuries but the incidence of post-traumatic nasal deformity remains high. For decrease the incidence of post-traumatic nasal deformity which require the guideline to optimize the management of acute nasal bone fracture. The aim of this study is analysis of post-traumatic nasal deformity according to Stranc classification. Method: We reviewed 310 patients with nasal bone fracture treated at our hospital from January of 2005 to December of 2006. Result: Post-traumatic complication were divided septal deviation, nasal bone deformity, temporary hyposmia and synechia. Nasal bone deformity include nasal bone deviation, hump, flat nose and minimal nasal bone irregularity. The incidence of total complication rate was 36.4%. The most common complication was nasal deformity(22.9%) followed by septal deviation(19.7%). The most common complication was septal deviation(20%) in frontal impact. The most common complication was nasal deformity(19.5%) in lateral impact. In frontal impact, the incidence of complication rate was plane II(68.8%) followed by plane I(29.9%) and plane III(16.7%). In lateral impact, the incidence of complication rate was plane II (78.8%) followed by plane III(61.5%) and plane I(42.7%). Conclusion: This result can be used to improve longterm results and to reduce the incidence of post-traumatic nasal deformity by predict complication of nasal bone fracture according to Stranc classification.
Purpose: The nasal bones are the most common fracture sites of the facial bones, and a careful reduction may still result in secondary deformities, such as saddle nose, deviated nose, hump nose etc, requiring secondary cosmetic rhinoplasty. Therefore, this study examined the clinical characteristics of nasal bone fractures to propose guidelines for patient selection and surgical procedures to achieve more satisfactory results and to prevent secondary deformities with simultaneous augmentation rhinoplasty and bony reduction. Methods: The study was based on 26 out of 149 nasal bone fracture patients who underwent simultaneous augmentation rhinoplasty with bony reduction between May 2008 and April 2009. Retrospective analysis was performed according to the clinical data, surgical techniques and postoperative results. Results: Of the 26 patients, there were 15 males and 11 females. The incidence according to the Stranc's classification revealed that 62% of patients were injured by a frontal impact and 38% by a lateral impact. Frontal impact plane I (50%) was the most frequent type. At the follow up, 18 (81.2%) out of 22 patients were satisfied with their postoperative outcome, and the remaining 4 patients were fair. No one was dissatisfied. However, 5 cases in 3 patients (23%) had some complications; minimal implant deviation in 2 cases, minor irregularity on the nasal dorsum in 2 cases and palpable implant movement under palpation in 1 case. None of these cases required surgical correction. Conclusion: With the proper guidance, simultaneous augmentation rhinoplasty with bony reduction can prevent secondary deformities and satisfy the cosmetic outcomes.
Background: Nasal fractures have a tendency of resulting in structural or functional complications, and the results can vary according to the type of nasal bone fracture. The aim of this study was to evaluate the objective postoperative results according to the type of nasal bone fractures. Methods: We reviewed 313 patients who had a closed reduction of nasal bone fracture. The classification of nasal bone fracture by Stranc and Robertson was used to characterize the fracture type: frontal impact group type I (FI), frontal impact group type II (FII), lateral impact group type I (LI), lateral impact group type II (LII), and comminuted fracture group (C). For each patient, we tried to use the same axial image section of computed tomographic (CT) scans before and immediately after operation. Postoperative outcomes were classified into 4 grades: excellent (E), good (G), fair (F), and poor (P). We also analyzed postoperative complications by fracture type. Results: Regarding the postoperative CT images, 189 subjects showed E results, 99 subjects showed G, 18 subjects showed F, and 7 subjects showed P reduction. The rate of operation results graded as E by each fracture type was 66.67% in FI, 52.0% in FII, 64.21% in LI, 62.79% in LII, and 21.74% in C. Complications of FI (7.14%), LII (13.95%), and C (13.04%) groups occurred more than in the FII (4.00%) and LI (4.21%) groups. Conclusion: It seems that the operation result by fracture type was better in the FI, LI, and LII type than the FII and C type; after one month, however, LII type showed more complications than other types. The septal fracture can be thought to affect early reduction results in nasal bone fractures.

Background: Nasal bone fracture is one of the most common facial bone fracture types, and the surgical results exert a strong influence on the facial contour and patient satisfaction. Preventing secondary deformity and restoring the original bone state are the major goals of surgeons managing nasal bone fracture patients. In this study, a treatment algorithm was established by applying the modified open reduction technique and postoperative care for several years. Methods: This article is a retrospective chart review of 417 patients who had been received surgical treatment from 2014 to 2015. Using prepared questionnaires and visual analogue scale, several components (postoperative nasal contour; degree of pain; minor complications like dry mouth, sleep disturbance, swallowing difficulty, conversation difficulty, and headache; and degree of patient satisfaction) were evaluated. Results: The average scores for the postoperative nasal contour given by three experts, and the degree of patient satisfaction, were within the "satisfied" (4) to "very satisfied" (5) range (4.5, 4.6, 4.5, and 4.2, respectively). The postoperative degree of pain was sufficiently low that the patients needed only the minimum dose of painkiller. The scores for the minor complications (dry mouth, sleep disturbance, swallowing difficulty, conversation difficulty, headache) were relatively low (36.4, 40.8, 65.2, 32.3, and 34 out of the maximum score of 100, respectively). Conclusion: Satisfactory results were obtained through the algorithm-oriented management of nasal bone fracture. The degree of postoperative pain and minor complications were considerably low, and the degree of satisfaction with the nasal contour was high.
Purpose: Many authors reported about the posttraumatic nasal aesthetic complications. However, the studies for functional or intranasal complications are not enough yet. We identified relatively high prevalence of nasal obstruction and olfactory dysfunction in nasal synechiae, and the synechiae formation was a frequently occurred after the nasal bone reduction. And then, the aim of this study is to identify the usefulness of the treatment of intranasal synechiae. Methods: We reviewed the data from 10 patients with symptomatic intranasal synechiae from June 2007 to June 2009. We enforced evaluation with preoperative CT in all patients but postoperative CT within complicated patients. We studied 10 patients with intranasal synechiae who had persistence postoperative symptoms. We studied the patients who were operated by removal of synechiae and ancillary surgical treatments in the last two years. Results: In the previous report, the incidence of intranasal synechiae was 15% (n=62) and symptomatic synechiae was 16% (10/62). We classified the nasal bone fracture according to Stranc classification. In this paper, the incidence of treated intranasal synechiae was 13% (2/15) in Frontal Impact (FI) Type I, 11% (2/18) in FI Type II, 100% (2/2) in FI Type III, 0% (0/2) in Lateral Impact (LI) Type I, 25% (3/12) in LI Type II, and 33% (1/3) in LI Type III, respectively. After removal of synechiae, all patients improved nasal obstruction and little improved olfactory disturbance. Conclusion: Simple removal of synechiae by scissors improved postoperative symptoms and complications such as nasal obstruction and olfactory dysfunction. After removal of synechiae, all patients improved nasal obstruction, however, little improved anosmia. So, we thought that olfactory dysfunction may result in many intranasal factors. First of all, education of delicate procedure regarding this subject should be empathized accordingly.
Background: The epidemiology of nasal fractures varies according to factors such as the era and area of the study, as well as the age of the patient. We compared the characteristics and causes of pediatric nasal fractures. Methods: A total of 2,321 patients with nasal fractures from 2010 to 2017 were examined. The patients were divided into age groups using the Korean school system of age classification. The causes of injury were divided into five groups: violence, fall or slip down, sports, road traffic accidents, and others. Fractures were classified using the Stranc and Robertson standard: vector of force and plane of fracture. Results: Violence was the most common cause of nasal fracture in patients older than 12 years. Violence was a significantly less frequent cause among patients younger than 12 years old than among adolescent and adult patients. Nasal fractures due to violence were not observed in patients younger than 10 years. Plane 2 and lateral force fractures were the most common; however, in patients younger than 12 years, frontal force fractures were significantly more frequent than were lateral force fractures. Conclusion: As children may simply be injured due to a fall or slip down, it is important for the parents and guardians to ensure their safety. As they become older, children should abstain from violence and be monitored. It is therefore very important to ensure that the environment is free of violence in order to prevent such injuries.
Background: Nasal bone fractures are the most common type of facial bone fracture, but are under-studied in adults above 65 years of age. Therefore, we investigated the epidemiology and patterns of nasal bone fractures among older adults in comparison to different age groups. Methods: This retrospective study included 2,321 nasal bone fracture patients who underwent surgery at our hospital from January 2010 to December 2017. The patients were classified by age as preschoolers, school-age children, young and middle-aged adults, and the elderly. We performed pairwise comparisons between elderly patients and each other age group in terms of sex, cause of injury, and fracture type. Results: The 2,321 nasal bone fracture patients included 76 elderly patients (50 men [65.8%] and 26 women [34.2%]). In these patients, the two most common injury causes were falling or slipping down (n= 39; 51.3%) and road traffic accidents (n= 19; 25.0%). According to the Stranc and Robertson classification, the most common force vector was lateral, and plane 2 fractures with lateral forces predominated. Conclusion: The elderly showed similar patterns of nasal bone fractures to those observed in young and middle-aged adults, but significant differences from preschoolers (in the injury vector and plane of fracture) and from school-age children (in the sex ratio and plane of fracture). However, elderly patients presented significantly different epidemiological characteristics compared to the other three groups. Therefore, it is necessary to improve the quality of life of the elderly and prepare for the upcoming super-aged society by taking steps to reduce the incidence and severity of fractures. Possible options for doing so include strengthening individual-level safety factors and expanding the social safety net for the elderly.

Purpose: Nasal bone fracture is the most common facial fracture. Although nasal bone fractures are considered to be minor injuries, the incidence of post-traumatic nasal deformity remains high. This study is designed to support management and patient satisfaction by classifying the simple nasal bone fracture, and survey the care method and result, which is compared with other studies. Methods: From May 2008 to April 2010, 334 patients with simple nasal bone fractures visited our hospital. The incidence, cause, types of nasal bone fracture, treatment, and complications are analyzed according to clinical examination, patient's record and radiographic images. Results: The mean age of patients was 30 years old, with 74% of the patients having been male, and 26% were female. The highest incidence of this fracture was between late teens to late twenties. The causes of nasal bone fracture were the following: having slipped or fallen down (39%), violence (16%), sports accident (14%), traffic accident (11%), industrial accident (6%), and others (16%). Patient's radiographic images were analyzed by Stranc and Robertson classification, frontal impact plane I was 38%, plane II was 16%, plane III was 1%, lateral impact plane I was 21%, plane II was 21%, and plane III was 3%. On average, surgical treatment was performed 7.2 days after trauma under general anesthesia. Closed reduction of nasal bone fracture was performed in 99% of patients. In patients with septal injuries, septal management was performed in 76.7% of cases. Aesthetic surgery was done on same time in 24% of patients. There were some complications, such as residual nasal deformity (7.2%), nasal obstruction (0.9%) and hyposmia (0.3%). Conclusion: According to this study, nasal bone fractures occurred commonly in physically active age groups (age 15~29 years), as a result of having slipped or fallen down, at afternoon and at night time. And it could be treated successfully by closed reduction and septoplasty by 7 days after trauma.
