Comparison of outcomes for general and local anesthesia in the management of nasal bone fractures: a meta-analysis.

BACKGROUND: This meta-analysis aimed to perform a head-to-head comparison of the role of general anesthesia (GA) and local anesthesia (LA) in the management of patients with nasal bone fractures (NBFs). METHODS: PubMed, Embase, and Web of Science were comprehensively searched. Studies investigating the clinical outcomes of GA and LA in the management of NBFs were included. Pooled odds ratios (OR) with the respective 95% confidence intervals (CIs) were calculated. Heterogeneity between the included studies was evaluated. The risk of bias in the included studies was assessed. RESULTS: Eight studies were included in this meta-analysis. The pooled ORs for cosmetic results, residual septal deformity, the need for further surgery, patients' satisfaction with the anesthesia procedure, and patients' satisfaction with the surgery results were 0.70 (95% CI 0.18, 2.64; z = - 0.53, p = 0.5957), 1.11 (95% CI 0.37, 3.30; z = 0.18, p = 0.8558), 1.19 (95% CI 0.65, 2.20; z = 0.56, p = 0.5760), 1.57 (95% CI 0.92, 2.69; z = 1.65, p = 0.0982), and 1.00 (95% CI 0.55, 1.80; z = - 0.00, p = 0.9974). CONCLUSIONS: Insignificant difference on clinical outcomes was observed between GA and LA in the manipulation of patients with NBFs, and the choice of anesthetic approach should be based on the tolerability of the methods and the severity of nasal fractures.

Surgical management of naso-orbito-ethmoidal fractures: a systematic review.

OBJECTIVE: Naso-orbito-ethmoidal fractures (NOE) fractures are uncommon but critical injuries. This review aims to investigate the patient factors, procedural factors, and postoperative outcomes associated with the surgical management of NOE fractures. STUDY DESIGN: PubMed and Scopus databases were systematically searched between 1993 and 2023 using the search strategy "(naso-orbito-ethmoidal OR nasoethmoid OR nasoorbitoethmoidal) AND fracture." Articles reporting clinical studies investigating the surgical management of NOE fractures were included. Articles that were duplicates, non-English, or non-full text; reported an unclear age range; reported insufficient data; and/or reported on a sample size less than 10 were excluded. Data on patient factors, procedural factors, and postoperative outcomes were extracted. RESULTS: Of the 412 articles identified, 6 eligible articles (retrospective case series) representing 95 adult cases and 84 pediatric cases were included. The mean ages were 29.0 and 10.2 years, respectively. Most cases were male (65.3%; 73.9%). Motor vehicle accidents were the most common mechanism of injury (79.2% and 50.0%, respectively). Coronal incision was the most common approach. Epiphora (n = 33) and scar problems (n = 21) were the most common complications in adult and pediatric cases, respectively. CONCLUSIONS: Further robust longitudinal studies with a clear description of fracture classification and surgical timing would be helpful. Gaps in knowledge include concomitant injuries, digitally-assisted applications, and risk factors for adverse outcomes.

Surgical treatment of nasal fractures may benefit from intraoperative 3D imaging.

This retrospective study aimed to assess the effects of the use of intraoperative three-dimensional (3D) imaging on outcomes in surgical treatment of nasal fractures. Furthermore, we investigated whether the use of intraoperative imaging improves outcomes and decreases the frequency of corrective surgeries compared to published literature. This retrospective descriptive study included patients who underwent operative treatment for nasal fractures with the use of intraoperative 3D imaging between January 2015 and January 2020 at a University Hospital. The primary outcome measure was patient satisfaction, which was assessed through patient charts about subjective esthetic problems and nasal obstruction. The secondary outcome measures were the number of intraoperative images and necessity of intra- and postoperative revisions. All the outcomes were evaluated using regression analysis. Of the 172 patients, secondary rhinoplasty and intraoperative revision were performed in 10 (6 %) and 93 (54 %) patients, respectively. Postoperatively, 19 (11 %) and 12 (7 %) patients complained of subjective esthetic problems and nasal obstruction, respectively. The intraoperative revision rate in patients undergoing surgical treatment of nasal fractures with intraoperative 3D imaging was >50 %. However, the incidence of postoperative secondary revision, nasal obstruction, and subjective esthetic problems was lower than that reported in the literature not having an intraoperative imaging. Our findings suggest that prompt quality control of the operative result enables immediate correction and prevents postoperative revision.

Usefulness of the Glove Finger Pad for Ultrasonography in Nasal Fracture Reduction.

The treatment of nasal bone fractures involves closed reduction, in which the reduction position is generally evaluated indirectly by visual examination and palpation. While more direct evaluation methods using ultrasonography can improve treatment outcomes, ultrasonography of the nasal bones requires acoustic coupling materials to hold the entire ultrasonography probe in close contact with the nose. We report the use of the Glove Finger Pad, a homemade acoustic coupling material made from a medical glove. The Glove Finger Pad is easy to prepare and use and produces good images. We believe that the Glove Finger Pad will further enhance the usefulness of ultrasonography for the treatment of nasal fractures.

Diagnostic utility of ultrasound in pediatric nasal bone fractures: a systematic review and meta-analysis.

Ultrasonography, a radiation-free and cost-effective modality, stands out as a promising tool for evaluating nasal bone fractures. Despite limited literature on its pediatric application, there is an increasing recognition of its potential to enhance diagnostic precision. To evaluate the diagnostic efficacy of ultrasound in detecting pediatric nasal bone fractures. Employing established guidelines, a systematic review and meta-analysis were conducted through a comprehensive literature search in PubMed, Scopus, Web of Science, and Embase databases until December 5, 2023. Inclusion criteria encompassed studies reporting diagnostic accuracy measures of ultrasound in pediatric patients with nasal bone fractures. Data extraction and analysis were undertaken for the selected studies. Involving four studies with 277 patients, ultrasound demonstrated a pooled sensitivity of 66.1% (95% CI: 35.1-87.5%) and specificity of 86.8% (95% CI: 80.1-91.4%) in diagnosing pediatric nasal fractures. The area under the receiver operating characteristic curve (AUC) was 0.88 (95% CI: 0.72-0.93). After excluding an outlier study, sensitivity and specificity increased to 78.0% (95% CI: 65.6-86.9%) and 87.8 (95% CI: 78.1-93.6%), respectively, with an AUC of 0.79 (95% CI: 0.75-0.94). Pooled positive and negative likelihood ratios were 5.11 (95% CI: 2.12-9.15) and 0.40 (95% CI: 0.14-0.77) before exclusion and 6.75 (95% CI: 3.47-12.30) and 0.26 (95% CI: 0.15-0.40) after exclusion of an outlier study, respectively. This study highlighted ultrasonography's utility in diagnosing pediatric nasal bone fractures with high accuracy and specificity. However, caution is advised in relying solely on ultrasound due to suboptimal overall diagnostic performance, evident in likelihood ratios.

Does performing manipulation of nasal bones under local anaesthetic beyond two weeks after injury affect outcomes? A prospective study during the SARS-CoV-2 pandemic.

Introduction: ENTUK guidelines recommend that manipulation of nasal bones (MNB) should be performed within 14 days of injury. However, evidence suggests treatment under general anaesthetic remains effective up to 5 weeks after injury. With the SARS-CoV-2 pandemic leading to delays in referral and limited access to theatre, local practice changed to offer delayed MNB under local anaesthetic. This prospective study assesses the effectiveness of MNB delayed until 3 weeks or later from time of injury when performed mostly under local anaesthetic. Methods: Data was prospectively collected between April and November 2020. All patients referred to ENT with a new nasal bone deformity presenting more than 21 days after injury were included. Demographic information, injury details and patient satisfaction was recorded for each patient. Results: 11 patients were included. Average age was 32.6 years (Range 8-65 years). 10 procedures (91%) were performed under local anaesthetic, with 1 (9%) performed under general anaesthetic. 9 patients (82%) gained complete reduction of the deformity, and 1 patient (9%) gaining partial reduction. 10 patients (91%) patients were satisfied with the cosmetic outcome. Conclusion: This study supports the small volume of recent literature showing that delayed manipulation of nasal bones is effective and additionally demonstrates that efficacy is maintained when performed under local anaesthetic.

The Management of Posttraumatic Nasal Deformities.

Nasal bone fractures are the most common fractures of the facial skeleton and are often accompanied by bony, cartilaginous, and soft tissue injuries. These injuries are often complex, and when untreated or inadequately treated, can lead to posttraumatic nasal deformity. The most common deformities are the crooked nose and the saddle nose. Both deformities may result in significant cosmetic and functional concerns. The treatment of these deformities can be complex, requiring careful evaluation of the nose and thoughtful planning to correct the cosmetic deformity and restore functional integrity. The rhinoplasty surgeon will benefit from having a large repertoire of techniques to achieve these repairs. In this article, we discuss the options and concepts for the management of nasal bone fractures as well as complicated posttraumatic nasal deformity. Level of evidence is not available.

Analysis of Nasal Bone Fractures: A 17-year Study of 3785 Patients.

In our previous study, we classified nasal bone fractures into 6 types based on computed tomography and the patterns of the nasal bone fractures (NBF) in 503 patients treated between 1998 and 2004. In the present study, we analyzed 3785 patients treated between 2005 and 2021. The age, sex, etiology, associated injuries, pattern of fractures, and treatments were reviewed, and radiographic studies were analyzed. The highest incidence was in the age group of 10 to 19 years (N=870, 23.0%), followed by 20 to 29 years (N=792, 20.9%) and 30 to 39 years (N=635, 16.8%). The most common causes of injury were slip or fall-down (42.3%), violence (24.3%), sports (19.2%), traffic accidents (8.9%), and work-related (5.3%). Most of the patients had tenderness (96.1%) and swelling (78.8%). Other findings were depression (27.1%) and nasal deviation (25.8%). Crepitus was heard in only 0.4% of the patients. The patterns of the NBFs classified by computed tomography findings were type IIA (unilateral simple fracture with displacement/without telescoping, 1283 cases, 33.9%), IIB (bilateral simple fracture with displacement/without telescoping, 786 cases, 20.8%), IIAs (unilateral simple fracture with septal fracture and displacement/without telescoping, 566 cases, 14.9%), IIBs (bilateral simple fracture with septal fracture and displacement/without telescoping 530 cases, 14.0%), I (simple fracture without displacement, 522 cases, 13.8%), and III (comminuted with telescoping or depression, 98 cases, 2.6%). In most of the cases (3,666, 96.9%), closed reduction was performed. The present analysis is one of the largest data sets on NBF in Korea, which could provide reference values for diagnosing and managing nasal bone fractures.

Pediatric Nasoorbitoethmoid Fractures: A Single Institution's 15-Year Experience.

BACKGROUND: Nasoorbitoethmoid (NOE) fractures impact growth of the craniofacial skeleton in children, which may necessitate differentiated management from adult injuries. This study describes characteristics, management, and outcomes of NOE fractures in children seen at a single institution. METHODS: A retrospective review of patients under 18 years who presented to our institution from 2006 to 2021 with facial fractures was conducted; patients with NOE fractures were included. Data collected included demographics, mechanism of injury, fracture type, management, and outcomes. RESULTS: Fifty-eight patients met inclusion criteria; 77.6% presented with Manson-Marcowitz Type I fractures, 17.2% with Type II, and 5.2% with Type III. The most common cause of injury was motor vehicle accidents (MVAs, 39.7%) and sports (31%). Glasgow Coma Scale and injury mechanism were not predictive of injury severity in the pediatric population ( P =0.353, P =0.493). Orbital fractures were the most common associated fractures (n=55, 94.8%); parietal bone fractures were more likely in Type III fractures ( P =0.047). LeFort III fractures were more likely in type II fractures ( P =0.011). Soft tissue and neurological injuries were the most common associated injuries regardless of NOE fracture type (81% and 58.6%, respectively). There was no significant difference in type of operative management or in the rates of adverse outcomes between types of NOE fractures. CONCLUSIONS: These findings suggest that pediatric NOE fractures, although rare, present differently from adult NOE fractures and that revisiting predictive heuristics and treatment strategies is warranted in this population.

Pediatric Nasal and Septal Fractures.

Pediatric nasal bone and septal fractures represent a large number of craniofacial injuries in children each year. Due to their differences in anatomy and potential for growth and development, the management of these injuries varies slightly from that of the adult population. As with most pediatric fractures, there is a bias toward less-invasive management to limit disruption to future growth. Often this includes closed reduction and splinting in the acute setting followed by open septorhinoplasty at skeletal maturity as needed. The overall goal of treatment is to restore the nose to its preinjury shape, structure, and function.

Introduction: Nasal fractures are the most common fractures of the maxillofacial region. However, Cuban literature on the subject is scarce and outdated, so the motivation for this research arose. Objective: To characterize patients with nasal fractures treated in a Cuban university hospital in a clinical and epidemiological manner. Methods: An observational, descriptive and cross-sectional study was carried out in patients treated at the Maxillofacial Surgery Service of the University General Hospital. "Carlos Manuel de Céspedes" of Bayamo, Granma province, Cuba, from January 1 to December 31, 2020. Clinical, epidemiological and therapeutic variables were studied. Results: 99 patients were included, of whom 74 (74.75 percent) were male. In 44.44 percent of the cases the ages were between 21 and 40 years. Fifty patients (50.51 percent) had fractures resulting from interpersonal violence. Ninety-seven patients (97.98 percent) presented epistaxis. Fifty-nine patients (59.60 percent) received closed reduction associated with nasal packing and external fixation with plaster cast. Conclusions: Male gender and age group 21 to 40 years predominated. The main etiology was interpersonal violence. Epistaxis was present in most cases. Closed fractures prevailed, as well as those with laterally deviated dorsum(AU)

The Efficacy of Sequential Intranasal Packing Removal in Overcorrected Nasal Bone Fracture: Evaluation With Computed Tomography.

BACKGROUND: Despite the evolution of new techniques to treat nasal bone fractures, closed reduction with appropriate palpation and inspection is one of the critical basic tools to treat nasal bone fractures properly. Despite its rarity, overcorrection after closed reduction of the nasal bone fracture could happen even with experienced surgeons. This study hypothesized that sequential packing removal is mandatory for optimal outcomes based on the preoperative and postoperative Computed Tomography scans in overcorrected cases. This is the first study to evaluate the efficacy of sequential nasal packing removal assessed by facial CT scans. METHODS: In this retrospective study, we evaluated the medical records and preoperative and postoperative facial Computed Tomography scans of 163 patients with nasal bone fractures treated with a closed reduction from May 2021 to December 2022. Preoperative and Postoperative CT scan was routinely used to assess the outcome. Merocels were used for intranasal packing. In overcorrected cases based on immediate postoperative CT scan, we routinely removed the intranasal packing on the overcorrected side first immediately. On postoperative day 3, we removed the remaining intranasal packing on the other side. We assessed additional postoperative CT scans on postoperative two to three weeks. RESULTS: With sequential packing removal starting on the day of surgery, all overcorrected cases were successfully corrected clinically and radiologically without noticeable complications. Two representative cases were presented. CONCLUSION: Sequential nasal packing removal provides significant benefits in overcorrected cases. An immediate postoperative CT scan is also vital to do this procedure. This strategy is advantageous if the fracture is significant and there is a substantial possibility of overcorrection.

Closed reduction of nasoseptal fractures: key concepts for predictable results.

Nasal complex injuries are the most common facial fracture encountered in the trauma population. Multiple surgical techniques for treatment of these fractures have been described with varying results. The goal of this study was to review the efficacy of closed reduction of nasal and septal fractures using a technique based upon several key concepts. We reviewed the records of patients who had undergone isolated nasal and/or septal fractures with closed reduction at our institution between January 2013 and November 2021. Inclusion criteria consisted of preoperative CT imaging, surgical treatment within fourteen days of initial injury, and follow up of at least one year. All patients were treated under general or deep sedation. The same surgical technique was applied with closed reduction of the septum and nasal bones with internal and external postoperative splints. Of the 232 records initially reviewed, 103 met inclusion criteria. Four patients had undergone revision septorhinoplasty (3.9%). Mean (range) follow up was 2.7 (1-8.2) years. Three patients had undergone revision nasal repair due to persistent airflow obstruction with complete resolution of symptoms after revision. The other patient received multiple revisions at another institution as a result of their dissatisfaction with cosmesis without improvement. Closed reduction of nasal and septal fractures can be a highly successful procedure and yield predictable results, limiting the need for post-traumatic open septorhinoplastic surgery. Five critical concepts of nasal fracture repair can help surgeons achieve predictable functional and cosmetic results: selection, timing, anaesthesia, reduction, and support.

Flipped Nasal Bone Fracture: Peculiar Fracture Pattern in a Pediatric Patient.

Fractures to the facial bone in the pediatric population often show a different fracture pattern from that of the adult population. In this brief report, the authors share their experience with a nasal bone fracture in a 12-year-old child showing a bizarre fracture pattern, an inside-out displacement of the nasal bone. The authors share the detailed findings of this fracture and describe the method for reducing the fracture back to the proper position.

Precisely Closed Reduction of Nasal Bone Fracture Assisted With Plain Film Measurements Under the Picture Archiving and Communication System.

OBJECTIVES: To prevent aesthetic and functional deformities, precisely closed reduction is crucial in the management of nasal fractures. Plain film radiography (PF), ultrasonography (USG), and computed tomography can help confirm the diagnosis and classification of fractures and assist in performing closed reduction. However, no study in the literature reports on precisely closed reduction assisted with PF measurements under the picture archiving and communication system (PACS). METHODS: We retrospectively evaluated 153 patients with nasal bone fracture between January 2013 and December 2017. Surgeons conducted precisely closed reduction assisted with PF measurement of the distance between the fracture site and nasal tip under PACS on 34 patients (group A). Another group on 119 patients were reduced under surgeon's experience (group B). RESULTS: No significant differences in age, gender, Arbeitsgemeinschaft fur Osteosynthesefragen (AO) classification, and reduction outcome were observed between group A and group B (P > .05). The operative time of the group A was significantly lower (12.50 ± 4.64 minutes) compared to group B (23.78 ± 11.20 minutes; P < .001). After adjusted age, gender, and AO classification, patients in group A scored 10.46 minutes less on the operative time than those in group B (P < .001). In addition, the severity of nasal bone fracture (AO classification, ß = 3.37, P = .002) was positive associated with the operative time. CONCLUSIONS: In this study, closed reduction in nasal bone fracture assisted with PF measurements under PACS was performed precisely, thereby effectively decreasing operative time and the occurrence of complications. This procedure requires neither the use of new instruments or C-arm nor USG or navigation experience. Moreover, reduction can be easily performed using this method, and it requires short operative time, helps achieve great reduction, less radiation exposures, and is cost-effective.

Manipulation under anaesthesia of fractured nasal bones - a 10-year retrospective study.

BACKGROUND: Nasal bone fractures are treated by manipulation under general or local anaesthesia procedures. Data on long-term benefits of manipulation under local anaesthesia are limited. This study aimed to quantify the proportion of patients requiring septoplasty or septorhinoplasty after manipulation under general and local anaesthesia procedures. METHODS: Anonymised data were collected from electronic records of all patients who underwent manipulation under anaesthesia at our centre over a 10-year period, including demographics, manipulation under anaesthesia timing and further surgery requirements. RESULTS: The study identified 625 manipulation under general anaesthesia and 52 manipulation under local anaesthesia procedures. Manipulation under local anaesthesia procedures were performed earlier (local anaesthesia = 9 days, general anaesthesia = 15 days; p < 0.05) and were more likely to achieve manipulation (local anaesthesia = 83 per cent, general anaesthesia = 76 per cent; p < 0.05). There was no difference between techniques in the percentage of patients requiring further surgery. CONCLUSION: This paper describes a large cohort of patients who underwent manipulation under anaesthesia over a 10-year period. Manipulation under local anaesthesia procedures have increased since the coronavirus disease 2019 pandemic, and the results are comparable to manipulation under general anaesthesia, with reduced delays between injury and manipulation.

Efficacy of X-ray in the diagnosis of pediatric nasal fracture.

OBJECTIVE: Nasal fracture is one of the most common pediatric fractures, and diagnosis can be made with clinical findings or with radiographic imaging. The objective of this study is to determine the extent of x-ray utilization in decision-making regarding closed reduction of pediatric nasal fracture. METHODS: This a case-control study of 117 patients ages 0-18 with a diagnosis of nasal fracture seen at University Hospitals Cleveland Medical Center between January 2015 and January 2020. The exposure group had x-ray imaging of the nasal bones, and the control group had no x-ray imaging. RESULTS: A total of 59 (50.4%) patients had surgical intervention. The odds ratio to compare x-ray utilization to the control group for patients who underwent closed reduction surgery was .3951 (95% CI: 0.1848-0.8448, p-value = .0166). CONCLUSION: The statistical analysis suggests that x-ray use is associated with decreased rates of closed reduction surgery. It is likely that while not necessary for the diagnosis of nasal fracture, x-ray serves as an additional data point for diagnosis confirmation, and may reduce the rate of unnecessary surgery for false positive cases of nasal fracture.

Redução aberta de fratura nasal: relato de caso / Open reduction of nasal fracture: case report / Reducción aberta de la fractura nasal: reporte de un caso

As fraturas nasais são de grande incidência dentre as fraturas faciais, podendo envolver também outras estruturas da face. O diagnóstico é baseado no exame físico, o qual muitas vezes é dificultado devido ao edema formado na região. A palpação dos contornos ósseos, verificação de presença de crepitação nasal, alterações de permeabilidade e assimetrias locais são algumas das alterações sugestivas de fraturas nasais. Além disso, a inserção do ligamento cantal medial pode ser perdida devido ao trauma ou devido ao deslocamento ósseo em que ele se encontra inserido. Exames de imagem, como radiografias e Tomografias Computadorizadas, são utilizados para a visualização das fraturas ósseas e planejamento cirúrgico. A redução aberta dos ossos nasais é indicada para fraturas de maior complexidade e cominuição, tendo em vista o adequado reposicionamento dos ossos, cartilagens e ligamentos deslocados. Assim, o objetivo deste estudo é relatar a redução aberta de uma fratura dos ossos nasais com perda de inserção do ligamento cantal medial direito, sob anestesia geral... (AU)

Nasal fractures are of great incidence among facial fractures, and may also involve other facial structures. The diagnosis is based on physical examination, which is often hampered due to the edema formed in the region. Palpation of bone contours, checking for the presence of nasal crackling, changes in permeability and local asymmetries are some of the changes suggestive of nasal fractures. In addition, the insertion of the medial canthal ligament may be lost due to trauma or due to the bone displacement in which it is inserted. Imaging exams, such as radiographs and CT scans, are used for visualizing bone fractures and surgical planning. The open reduction of the nasal bones is indicated for fractures of greater complexity and comminution, in view of the appropriate repositioning of the bones, cartilage and dislocated ligaments. Thus, the aim of this study is to report the open reduction of a fracture of the nasal bones with loss of insertion of the right medial canthal ligament, under general anestesia... (AU)

Etiology of Nasal Bone Fracture: A Retrospective Analysis of 1,441 Patients in China.

ABSTRACT: Nasal bone fracture is the most common injury in the craniofacial area. Understanding the etiology of nasal bone fracture is important for the development of preventive public health programs. In this study, the authors retrospectively examined medical records to extract information about sex, age, injury time, injury cause, occupation, and place of residence (urban or rural) from 1441 patients with nasal bone fracture to investigate the etiology of nasal bone fracture in China. Among the 1441 patients, the ratio of males to females was 3.4:1. The mean patient age was 29.25 years. The most common occupation was student (31.02%). Violence was the most common cause of injury in male patients (35.82%), whereas slip-and-fall accidents were the most common cause in female patients (32.11%). Violence was the most common cause of injury in both urban and rural patients, and 74.19% were attacked by others without a weapon. This report provides important data about the etiology of nasal bone fracture in China and will help improve nasal bone fracture prevention measures.
