Purpose: Several authors reported about the post - traumatic nasal aesthetic complications. However, the study for functional or intra - nasal complications has been reported not enough. The aim of this study is to observe the incidence of intranasal synechia. Methods: We reviewed the data from 401 consecutive patients with nasal bone fracture from september 2006 to December 2007. We enforced evaluation with preoperative CT in all patients but postoperative CT within complicated patients. We classified the nasal bone fracture according to the anatomy and severity of fracture. Type I is nasal tip fracture(15%, n = 59), Type II is simple lateral without septal injury(38%, n = 152), Type III is simple lateral with septal injury(23%, n = 92), Type IV is closed comminuted(20%, n = 82), Type V is open comminuted or complicated(4%, n = 16). We studied 98 patients with nasal bone fracture who had postoperative symptoms or undergone postoperative endoscopic evaluation. And then we evaluated the postoperative endoscopic finding and nasal synechal formation after operation. Results: The incidence of intranasal synechiae was 15%(n = 62). According to the endoscopic findings, the incidence of intranasal synechiae was 10%(n = 6) in Type I, 8%(n = 12) in Type II, 16%(n = 15) in Type III, 24%(n = 20) in Type IV, and 56%(n = 9) in Type V. Additionally, the incidence of subjective nasal obstruction and olfactory dysfunction is 18%(n = 72) and 13%(n = 51). But the incidence of symptomatic synechiae of nasal obstruction and olfactory dysfunction is 92%(57/62) and 55%(34/62). Conclusion: We identified relatively high prevalence of nasal obstruction and olfactory dysfunction in nasal synechiae. Based on the results of this study, intranasal synechiae really caused airway obstruction(92%). Our data showed significant relationship between intranasal synechiae and severity of the fracture, because of increasing mucosal handling and destructive closed reductional procedures. First of all, education of delicate procedure regarding this subject should be empathized accordingly.
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: Many severe nasal bone fractures present with septal fractures, causing postoperative septal deviation and negatively affecting the patients' quality of life. However, when a septal fracture is absent, it is difficult to predict whether surgical correction can help minimize nasal septal deviation postoperatively. This study determined whether performing closed reduction on even mildly displaced nasal bone fracture could deter the outcome of septal deviation. Methods: We retrospectively reviewed the data of 116 patients aged 21-72 years who presented at the outpatient clinic and emergency room with fractures of nasal bones only without any involvement of the septum from January 2014 to December 2020. Patients were classified into three fracture type groups: A (unilateral), B (bilateral), and C (comminuted with depression). The degree of septal deviation was calculated by measuring the angle between the apex of the most prominent point and the crista galli in the coronal view on computed tomography images. The difference between the angles of the initial septal deviation and that of the follow-up was calculated and expressed as delta (Δ). Results: Closed reduction tended to decrease the postoperative septal deviation in all fracture types, but the values were significantly meaningful only in type A and B fractures. In the surgical group, with type A as the baseline, type B showed a significantly larger Δ value, but type C was not significantly different, although type C showed a smaller Δ value. In the conservative group, with type A as the baseline, the other fracture types presented significantly lower Δ values. Conclusion: For all fracture types, closed reduction significantly decreased the extent to which the nasal septum likely deviated. Therefore, when a patient is reluctant to undergo closed reduction, physicians should address the possible outcomes and prognosis of untreated nasal bone fractures.
Neurilemmoma is a benign, well-encapsulated neurogenic tumor that arises in cranial, peripheral, or autonomic nerves that have nerve sheaths containing schwann cells. From 16 to 45% of all neurilemmoma cases occur in the head and neck region and only about 4% of those cases are found in the nose and paranasal sinuses, but very rarely found in the nasal septum. Recently, we experienced a case of isolated neurilemmoma which arose from the nasal septum of a 30-year-old female patient who complained of nasal obstruction and postnasal drip. The mass was broadly based on the right anterior portion of the nasal septum and confined to the nasal cavity, displacing the lateral wall of the nasal cavity and middle turbinate, laterally and posteriorly, respectively. The tumor mass was completely excised through transnasal endoscopic surgery under general anesthesia. The final pathological diagnosis viewed under a microscope after H&E and anti S-100 protein stain was a benign neurilemmoma in which Antoni A type and B type both existed. This report presents a case of neurilemmoma which arose from the nasal septum with reviews of the clinicopathologic features.

Purpose: Closed reduction is most common treatment method for nasal bone fracture but it requires secondary correction operation commonly. For preventing secondary revision, we applied ultrasonography during closed reduction of nasal bone fracture and examined the result of operation. Methods: 80 patients were sorted into 2 groups, ultrasound-guided closed reduction group(n=40) and manual closed reduction group(n=40). We classified the unilateral fracture involving lower 1/2 of nasal bone into type I, the bilateral fracture involving lower 1/2 of nasal bone into type III and the fracture of upper 1/2 of nasal bone into type III. The occurrence rate of overcorrection and undercorrection were evaluated by comparing preoperative and postoperative MDCT(Multi Direction Computed Tomography). Results: In manual closed reduction group, overcorrection were found in 4 patients and undercorrection were found in 3 patients. In ultrasound-guided closed reduction group, overcorrection was not observed and undercorrection was observed in 2 patients. Conclusion: Intraoperative ultrasound evaluation of nasal bone fracture resulted in reduced occurrence rate of secondary nasal deformities, showed easier detection of the fractured site and have superiority upon simple physical examination or simple x-ray.
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.
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.
Background: All nasal bone fractures have the potential for worsening of olfactory function. However, few studies have studied the olfactory outcomes following reduction of nasal bone fractures. This study evaluates posttraumatic olfactory dysfunction in patients with nasal bone fracture before and after closed reduction. Methods: A prospective study was conducted for all patients presenting with nasal bone fracture (n=97). Each patient consenting to the study underwent the Korean version of Sniffin' Sticks test (KVSS II) before operation and at 6 month after closed reduction. The nasal fractures were divided according to the nasal bone fracture classification by Haug and Prather (Types I-IV). The olfactory scores were compared across fracture types and between preoperative and postoperative settings. Results: Olfactory dysfunction was frequent after nasal fracture (45/97, 46.4%). Our olfactory assessment using the KVSS II test revealed that fracture reduction was not associated with improvements in the mean test score in Type I or Type II fractures. More specifically, the mean posttraumatic Threshold, discrimination and identification score decreased from 28.8 points prior to operation to 23.1 point at 6 months for Type II fracture with septal fracture. Conclusion: Our study has revealed two alarming trends regarding post-nasal fracture olfactory dysfunction. First, our study demonstrated that almost half (46.4%) of nasal fracture patients experience posttraumatic olfactory dysfunction. Second, closed reduction of these fractures does not lead to improvements olfaction at 6 months, which suggest that olfactory dysfunction is probably due to factors other than the fracture itself. The association should be further explored between injuries that lead to nasal fracture and the mechanism behind posttraumatic olfactory dysfunction.

Background: Prophylactic antibiotics are used to prevent surgical wound infection; however, proper indications must be followed with careful consideration of the risks and benefits, especially in clean or clean-contaminated wounds. Nasal bone fractures are the most common type of facial bone fracture. The most common method for treating nasal bone fracture is closed reduction, which is performed inside the nasal cavity without an incision. The purpose of this study was to determine the need for antibiotic use in the closed reduction of nasal bone fractures. Methods: A retrospective study was conducted using data from the National Insurance Service Ilsan Hospital of the Republic of Korea between 2016 and 2018. The records of patients who underwent closed reduction of nasal bone fracture were reviewed and classified according to sex, age, comorbidities, perioperative antibiotic usage, postoperative complications, nasal packing, anesthesia type, surgeon's specialty, and operation time. Results: Among the 373 patients studied, the antibiotic prescription rate was 67.3%. Just 0.8% of patients were prescribed preoperative antibiotics only, 44.0% were prescribed postoperative antibiotics only, and 22.5% were prescribed both preoperative and postoperative antibiotics. There were no cases that satisfied the definition of "surgical site infection." Furthermore, 2.1% of infection-related complications (e.g., mucosal swelling, synechia, and anosmia) occurred only in the antibiotic usage group. The use of nasal packing, anesthesia type, and surgeon's specialty did not show any difference in infection-related complication rates. Conclusion: According to the study findings, the routine use of perioperative antibiotics is not recommended in uncomplicated nasal bone fracture surgery.
