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.

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.

Nasal Fractures: Acute, Subacute, and Delayed Management.

Nasal fractures are very common. The literature describes early intervention (<14 days) with closed techniques as cost-effective, minimizing the need for possible secondary surgeries and improved early patient satisfaction. However, the authors observe a measurably high rate of subsequent open treatment after closed treatment, particularly where there is significant septal involvement in the fracture. Moreover, delayed intervention (>3 months) with an open approach has many advantages over early closed technique, including lower revision rate, improved ability for rigid fixation and support, and the ability to correct severe dorsal or caudal L-strut deformities, nasal valve issues, and severe nasal bony deviation/deformities.

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.

Cosmetic Open Rhinoplasty in Acute Nasal Bone Fracture With Pre-Existing Deformity.

The simultaneous reduction of nasal bone fracture and cosmetic rhinoplasty is a challenging procedure, because of fracture severity and skeletal instability. Our aim was to investigate the surgical strategy and outcomes of cosmetic rhinoplasty according to the pre-existing nasal deformity when performing simultaneous reduction of nasal bone fracture and cosmetic rhinoplasty. In total, 71 patients who underwent cosmetic rhinoplasty were included. All patients were categorized according to pre-existing deformity, dorsal hump and irregularities, and deviation of the nose, wide nose, and flat nasal dorsum. The authors performed individual maneuvers to correct each deformity. Autologous tissue was used in all maneuvers for graft. Photoanalysis was performed to measure the deviation, nasal length, radix height, dorsal height, tip projection, nasofrontal angle, and nasolabial angle. Subjective evaluation of the functional and esthetic problems was confirmed through rhinoplasty outcome evaluation. In the analysis of the photographs, most patients presented improved scores ( P <0.05). The scores of satisfaction were significantly higher in the postoperative state ( P <0.05). As a postoperative complication, 2 cases of deviated tip occurred due to septal instability and were successfully revised with septoplasty and columellar strut graft. The authors created a harmonious face by evaluating, categorizing, and treating each deformity of the nose in patients with nasal fractures according to our algorithm.

Efficacy of closed reduction of nasal fractures-a retrospective analysis with focus on factors affecting functional and aesthetic outcomes.

BACKGROUND: Nasal bone fractures are the most common type of facial bone fractures. While the nasal anatomy and closed reduction techniques of nasal fractures are well described, there is a paucity of data reporting on the need for revision rhinoplasty. The objective of this study is to analyze the factors affecting the outcome and need for revision rhinoplasty in patients who underwent closed reduction for nasal bone fracture. METHODS: From 2010 to 2020, a total of 417 consecutive patients underwent closed nasal reduction. Medical files of the patients were reviewed retrospectively. The rate of rhinoplasty after fracture consolidation was determined. Factors influencing the need for revision rhinoplasty were assessed using univariable and multivariable logistic regression analyses. RESULTS: Forty-seven patients (11.3%) required revision rhinoplasty after fracture healing. Patients who had suffered an additional septum fracture were more likely to undergo rhinoplasty. The risk of the need for open revision rhinoplasty after fracture healing was increased for patients complaining of airway obstruction at the time of cast removal after closed reduction. CONCLUSION: A certain number of patients will require secondary revision rhinoplasty after closed reduction of a nasal fracture. Subjective airway obstruction at the time of cast removal after closed reduction is a predictor for revision rhinoplasty. Prospective studies are required to support the findings of this investigation.

Does a closed reduction improve aesthetical and functional outcome after nasal fracture?

BACKGROUND AND PURPOSES: How closed reduction (CR) to repair a nasal fracture affects the patient's quality of life (QoL) has not been investigated. Here, we assessed QoL before and after CR using disease-specific questionnaires and compared the QoL scores of patients with nasal fractures with normative scores from a reference cohort. METHODS: This was a prospective study of 96 patients with nasal fractures undergoing CR. Patients were interviewed about aesthetic, functional, and QoL issues before and after surgery using the Functional Rhinoplasty Outcome Inventory (FROI-17) and the Rhinoplasty Outcome Evaluation (ROE). Photographs of the nasal area were taken before and after surgery and reviewed. Data were compared with those from a reference cohort (n = 1000). RESULTS: Most fractures were type I (80.6%) and most were caused by sport-related accidents (36.5%). The ROE scores increased from 67.3 preoperatively to 73.4 postoperatively (p = 0.001). The FROI-17 also improved, indicating the overall effect of the nose on QoL (p = 0.002). Compared with the reference cohort, patients felt more affected by nasal symptoms before surgery (- 9.37, p = 0.02) than by more general aspects. ROE scores returned to normative values after surgery (p < 0.001). The postoperative cohort had lower scores for the FROI-17 item overall effects of the nose on QoL than the reference cohort did, although the nasal symptom score remained higher in patients than in reference controls. CONCLUSIONS: This study showed that CR can improve the aesthetical but not the functional outcome of the nose.

Effectiveness of Absorbable Plates for the Treatment of Nasal Septal Cartilage Fractures.

BACKGROUND: Nasal bone fractures are the most common type of facial fracture. Nasal bone fractures often occur in combination with septal cartilage fractures, because the nasal septal cartilage acts as a vertical strut and provides structural support for the nose and bilateral nasal airway. However, the treatment for nasal septal cartilage fracture remains controversial, and if untreated, nasal septal cartilage fracture can lead to various complications, such as nasal obstruction and posttraumatic nasal and septal deformity. This study aimed to evaluate the effectiveness and safety of our procedure in which septal cartilage fractures were treated with septoplasty using an absorbable plate as an internal splint. METHODS: Between January 2017 and November 2020, 21 patients with nasal septal cartilage fractures were treated with septoplasty using an absorbable plate as an internal splint. The severity of the septal cartilage fracture was graded from 0 to 3 according to the computed tomography septal grading system. The numeric graded scale of nasal septal cartilage fracture was evaluated preoperatively and 6 months postoperatively using a computed tomography scan. RESULTS: Of 21 patients with septal cartilage fractures, 12 were treated with a polycaprolactone (PCL) mesh plate, and 9 were treated with a polydioxanone (PDS) plate. In the PDS plate group, the preoperative numeric scale of nasal septal cartilage fracture was 2.50 (2.00-3.00), whereas the postoperative numeric scale was 1.00 (1.00-1.25, P = 0.023). In the PCL mesh plate group, the preoperative numeric scale of nasal septal cartilage fracture was 2.00 (2.00-3.00), whereas the postoperative numeric scale was 1.00 (1.00-1.50, P = 0.034). The effectiveness of the PCL mesh plate and that of the PDS plate group according to the septal grading scale were 1.45 (SD, 0.522) and 1.18 (SD, 0.603), respectively. However, these differences were not statistically significant. CONCLUSIONS: Our study shows that septoplasty using absorbable plates provides satisfactory and safe clinical outcomes in patients with nasal septal cartilage fractures.

Ferreira-Ishida Technique: Spare Roof Technique B. Step-by-Step Guide to Preserving the Bony Cap While Dehumping.

SUMMARY: For V-shaped nasal bones, the authors consider that ostectomy of the dorsal keystone area can be avoided, and this has led to the development of a new preservation technique: the spare roof technique B (or Ferreira-Ishida technique), where the bony cap is preserved. It includes six main steps, as follows. Step 1, draw on the surface of the skin the desired dorsal brow-tip aesthetic lines, the pyriform aperture, the rhinion, and the amount of triangular bone that has to be taken out to allow pushing-down the bony cap, and the transversal line in the beginning of the nasal hump. Step 2, release the upper lateral cartilages from the dorsal septum ("high septal strip"). Step 3, take out the amount of dorsal septum necessary to dehump. Step 4, perform the paramedian high parallel osteotomies exactly below the marked brow-tip dorsal aesthetic lines. Then, perform the second group of lower osteotomies, until the E-point, to achieve a triangular shape of bone in each side of the bony cap. Perform the ostectomy of the mentioned triangular areas. Release the lateral keystone area. Perform partial ultrasonic ostectomy endonasally, below the nasal bones, to promote the weakening of the transverse fracture line, in the sagittal plane just above the E-point. Push-down gently the rectangular bony cap with a Luc nasal forceps (19 cm) in a greenstick fashion. Perform lateral traditional osteotomies from high to low to high to narrow the bony bridge as much as is needed. Step 5, perform a regular L-shape Cottle septoplasty (if necessary). Step 6, suture the cartilaginous middle vault (upper lateral cartilages) to the dorsal aspect of the remaining septum.

A Novel Septoplasty Technique for Patients With Nasal Fractures.

ABSTRACT: Nasal structures have both functional and cosmetic significance. These structures maintain the shape of the nose and regulate the nasal airflow. During trauma, fractures of the nasal bone are frequently associated with nasal septum deviations. This can lead to the nasal bone collapsing and nasal obstruction. The septoplasty technique is a major surgical intervention to improve nasal obstructions, with the submucosal resection of the deviated septum. In the past, septoplasty was deferred until the nasal bone fracture was healed to reduce the postoperative risk of saddle-nose and flat nose deformities. Advances in technology have enabled surgeons to attempt septoplasty together with a closed reduction of the nasal bone fraction. It is most important to preserve the septal support structure during surgery. Hence, we advocate that the nasal septum be reset in the midline rather than removed, by modified endoscopic septoplasty.

Endoscopic Endonasal Repair of the Orbital Medial Wall Fracture Utilising Nasal Septal Cartilage as the Reconstructive Material.

BACKGROUND: To repair orbital medial wall fractures, otorhinolaryngologists often use the silicone sheet technique by inserting an inverted U-shaped silicone sheet into the middle meatus after the removal of fractured bones, and packing gauze inside the silicone sheet for several days to fix the shape of the medial wall. However, this method does not sufficiently reduce the orbital content. OBJECTIVE: To describe the surgical procedure to repair medial wall fractures using nasal septal cartilage as the reconstructive material. METHODS: First, endoscopic septoplasty is performed. Although the correction of the septal deviation is performed to secure the operative field, the nasal septal cartilage, except the L-strut is resected simultaneously. After septoplasty, the fractured bones of the lamina papyracea are removed from the herniated orbital contents, and then the orbital contents can be reduced without resistance by pushing laterally. Subsequently, the cartilage is inserted beneath the fracture edges of the orbital medial wall with great care to avoid entrapping the orbital soft tissue and extraocular muscles. RESULTS: The cartilage can be placed appropriately along the medial wall of the orbit. CONCLUSION: This technique enables to repair most cases of orbital medial wall fractures using the endoscopic endonasal approach alone without alloplastic implants.

A New Technique of Open Septal Reduction Using Polydioxanone Plates for Nasoseptal Fracture: Three-Dimensional Volumetric Analysis.

BACKGROUND: In this study, we designed a new technique for open septal reduction using a polydioxanone (PDS) plate and compared it with closed reduction (CR). METHODS: This study included 19 consecutive patients with nasoseptal fracture: 10 receiving open reduction with a PDS plate (PDS group) and 9 undergoing CR group. Open septal reduction was performed after CR for nasal bone fracture. A mucoperichondrial flap was unilaterally elevated, and the deviated septal cartilage was reduced. The PDS plate was inserted horizontally above the vomerine suture. Surgical outcome was analyzed with three-dimensional volumetry and with a quality-of-life scale for nasal obstruction (Nasal Obstruction Symptom Evaluation scale). RESULTS: Complications included 1 case of septal perforation in the CR group and 1 case of PDS exposure and septal hematoma in the PDS group. In the three-dimensional volumetric analysis of the PDS group, the median value of the nasal cavity change significantly differed between 1.14 mL (interquartile range; 0.46-2.4) at the preoperative computed tomography scan and 0.33 mL (interquartile range; -0.22 to 1.29) at the postoperative computed tomography scan (∗∗P = 0.0039). The Nasal Obstruction Symptom Evaluation scale revealed significant improvement in nasal obstruction postsurgically (median value, 42.5-7.5; ∗P = 0.0139) in the PDS group. CONCLUSIONS: Polydioxanone plates potentially present a new concept of open septal reduction in terms of septal reinforcement compared with the subtractive approach of open septal reduction.

Nasal Fractures.

This article outlines current methods in the evaluation and management of nasal fractures including clinical workup, imaging, and treatment.

Etiology, pattern, and treatment of nose fractures: A 10-year cross-sectional cohort retrospective study.

BACKGROUND: Determining the etiology, epidemiology, pattern, and treatment of nasal bone fractures and the associated soft tissue injuries in a population will be beneficial for the prevention, rapid and correct diagnosis, and adequate management of this pathology in order to minimize postoperative complications. PATIENTS AND METHODS: This study retrospectively evaluated the patients admitted and treated for nasal bone fractures in a university clinic of oral and maxillofacial surgery in Romania over a 10-year period. Following statistical analysis, evaluation and correlation of the monitored variables, a P value < 0.05 was considered statistically significant. RESULTS: Nasal bone fractures had the highest incidence among men (88.30%), aged 20-29 years (33.33%), with no education (33.33%), interpersonal violence being the main cause in this category of patients (P = 0.004; P = 0.005; P = 0.005). In urban environment (55.9%), nasal bone fractures through aggression and road traffic accidents were predominant, while in rural areas (44.10%), those caused by domestic accidents and animal attacks prevailed (P = 0.551). Nondisplaced (81.10%), closed (85.60%) and involving the nasal septum fractures (51.35%) were preponderant. Hematoma was the most frequent associated soft tissue injury (86.49%), its incidence being increased in the case of displaced (P = 1.000) and open fractures (P = 0.692). The most frequent treatment method was close nasal reduction (CNR) + closed septoplasty (51.35%). The most frequent complication was malunion (7.2%), secondary to CNR without septoplasty (P = 0.037). CONCLUSIONS: The main etiology of nasal bone fractures was interpersonal violence, which mainly affected men, aged 20-39 years, with a low level of education, living in urban areas. Implementing laws to fight interpersonal aggression and increase the education level of the population would lead to a considerable reduction in the incidence of this pathology. Patients treated by CNR + closed septoplasty and ORIF had the best postoperative evolution. Immediate septoplasty in the case of associated septal fractures significantly decreased the rate of postoperative complications.

Manejo de la vía aérea mediante intubación submental en fracturas maxilofaciales / Airway management by submental intubation in maxillofacial fractures

La intubación submentoniana es útil en procedimientos quirúrgicos en donde la intubación nasotraqueal está contraindicada y la intubación orotraqueal no es ideal debido a la fijación intermaxilar. Este informe describe dos pacientes masculinos que se presentaron al Hospital Nacional Rosales, en el servicio de Cirugía Maxilofacial de El Salvador, con historia de sufrir accidente de tránsito. El primer caso evidenció al examen radiológico fractura simple y desplazada de sínfisis mandibular, fractura simple huesos propios nasales y desviación del tabique nasal. El segundo caso es un paciente con fractura de sínfisis y doble cóndilo mandibular que presentaba imposibilidad a la apertura bucal. A través de la técnica del cirujano maxilofacial Hernández Altemir (España), el tubo endotraqueal atraviesa una incisión extraoral en la región submentoniana del suelo de la boca, para poder practicar reducción abierta de fracturas faciales, logrando adecuada oclusión, con mínimos cuidados posoperatorios y con una cicatriz estética. Al terminar la cirugía, la posición del tubo endotraqueal regresa a su posición original y el paciente evoluciona satisfactoriamente

Submental intubation is useful in surgical procedures where nasotracheal intubation is contraindicated and orotracheal intubation is not ideal due to intermaxillary fixation. This report describes two male patients who presented to the Rosales National Hospital, in the Maxillofacial Surgery service of El Salvador, with a history of suffering a traffic accident. The first case showed a simple and displaced fracture of the mandibular symphysis, simple nasal bone fracture and deviation of the nasal septum on radiological examination. The second case is a patient with a symphysis fracture and a double mandibular condyle that presented an inability to open the mouth. Through the technique of the maxillofacial surgeon Hernández Altemir (Spain), the endotracheal tube passes through an extraoral incision in the submental region of the floor of the mouth, in order to perform open reduction of facial fractures, achieving adequate occlusion, with minimal postoperative care and with an aesthetic scar. At the end of the surgery, the position of the endotracheal tube returns to its original position and the patient evolves satisfactorily

Unique case of a post-traumatic nasoseptal arteriovenous malformation.

Extracranial manifestation of arteriovenous malformations (AVMs) is uncommon. Nasoseptal AVMs are an even rarer entity. In this case report, we present an interesting and first-of-its-kind case of the development of a left nasoseptal AVM in a 60-year-old man after a fall. This was likely post-traumatic, unlike the usual congenital AVMs described in the literature. The patient was managed conservatively with regular follow-up for the AVM as he was asymptomatic.

Nasal fractures: a dedicated clinic providing reduction under local anaesthesia improves time to manipulation.

INTRODUCTION: Guidelines for nasal injury state that assessment should be at 7-10 days post-injury and manipulation within 14 days. We performed a plan, do, study, act improvement cycle to assess whether a dedicated nasal fracture service led to better outcomes. MATERIALS AND METHODS: A retrospective study was carried out of all patients undergoing manipulation under anaesthesia for nasal trauma between February 2013 and December 2016 in a district general hospital. A dedicated nasal fracture clinic providing manipulation under local anaesthesia was implemented followed by a prospective study of all patients presenting to the clinic between February and November 2017. Main outcome measures included time from injury to otolaryngology assessment, time from injury to manipulation and incidence of secondary septorhinoplasty. RESULTS: The retrospective series involved 525 patients including 381 males (72.6%) and 144 females (27.4%). Mean time from injury to assessment was 10 days. Mean time from injury to surgery was 14.5 days. Mean time from assessment to surgery was five days. The incidence of septorhinoplasty was 2.3%. The prospective series involved 119 patients including 78 males (65.5%) and 41 females (34.5%). Following implementation of a nasal fracture clinic, mean time from injury to assessment and manipulation was 6.1 days and 5.4% of patients underwent septorhinoplasty for secondary deformity. DISCUSSION: Implementation of a nasal fracture clinic providing reduction under local anaesthesia reduced the time to assessment and manipulation. The incidence of septorhinoplasty is low following reduction under general or local anaesthesia. Assessment earlier than seven days is feasible and advice for referral can be changed accordingly.

Nasal Bone Fractures: Analysis of 1193 Cases with an Emphasis on Coincident Adjacent Fractures.

Importance: The nasal bone is one of the most commonly fractured bones of the midface. However, the frequency of coincident fractures of adjacent bones such as the frontal process of the maxillary bone, nasal septum, and medial or inferior orbital walls has not been fully evaluated. Objective: The purpose of this study was to investigate the incidence of fractures of adjacent structures in the setting of a nasal bone fracture. Second, we propose a new classification system of nasal bone fractures with involvement of adjacent bony structures. Design, Setting, and Participants: One thousand, one hundred ninety-three patients with midfacial fractures were retrospectively reviewed. The characteristics of fractures of the nasal bone and the incidence of coincident fractures of the frontal process of maxilla, bony nasal septum, medial, or inferior orbital walls were analyzed. Exposure: All patients included in the study presented with nasal trauma. Main Outcomes and Measures: The coincident fractures of adjacent midfacial structures were assessed, and a new classification of midfacial fractures based on computed tomography (CT) scan images was proposed. Results: Among the 1193 cases, bilateral fractures of the nasal bone were most common (69.24%), and coexistent fracture of the frontal process of the maxilla and bony nasal septum was 66.89% and 42.25%, respectively. Coincident fracture of the orbital walls was observed in 16.51% of cases. The major etiology of fracture for the younger and elderly groups was falls, compared with assault as the most common etiology in the adult group. A classification scheme was generated in which fractures of the nasal bone were divided into five types depending on coexisting fractures of adjacent structures. Conclusions and Relevance: External force applied to the nasal bone can also lead to coexistent fracture of adjacent bony structures including the frontal process of the maxilla, nasal septum, and orbital walls. The proposed classification of nasal fracture based on CT imaging helps to incorporate coincident disruption of adjacent structures.
