Comparison of Blunt Force (Mechanical), Piezoelectric, and Electric Instruments in Bony Vault Management.

The reshaping of the nasal pyramid has evolved significantly over the past 20 years. Mechanical instruments have been refined to minimize the bone trauma of osteotomies. However, these instruments can inadvertently cause radiated fractures and comminuted fractures, which compromise bone stability and can create surface defects. Electric and piezoelectric instruments (PEI) have been developed to address these issues. PEI instruments are selective unlike electric instruments. These instruments allow for precise rhinosculpture and osteotomies under direct visual control. The article reviews the advantages and disadvantages of each method by comparing them for the most frequently performed procedures on the nasal bone pyramid in rhinoplasty.

Wedge Osteectomy of Bony Cap in Rhinoplasty: Minor Nasal Bone Hump Reduction.

BACKGROUND: Hump reduction with traditional ostectomy is an invasive procedure performed in aesthetic rhinoplasty. Natural and flawless nasal dorsum can be obtained with wedge ostectomy (WO) technique. OBJECTIVE: The objective of this study is to describe the nasal dorsum WO technique and examine its effectiveness in correcting nasal dorsum with absent and minor humps in patients undergoing aesthetic rhinoplasty. MATERIALS AND METHODS: Senior author performed 488 rhinoplasty and septorhinoplasty operations from April 2009 to April 2021. After exclusion of major hump patients, the remaining 312 patients had a secondary evaluation for suitability for wedge ostectomy. After secondary examination, 87 patients, including 19 with absent humps (0 mm) and 68 with small humps (1-3 mm) were operated. RESULTS: Nasal bone hump reduction with WO has proven satisfactory results in majority of patients, minimal revision in done in five patients but no complications were occurred related to this method. CONCLUSIONS: Nasal dorsum WO provides lesser invasive approach to bony hump reduction in selected patients, ensuring bone cortex continuity in nasal dorsum. It decreases possible dorsal nasal irregularities associated with conventional coronal plane ostectomies. At the same time, it provides a natural and anatomically accurate nasal dorsum.

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.

Rhinoplasty for post-traumatic deviation of the nose with non-incisional external perforated osteotomy.

Osteotomy is often necessary for the repair of post-traumatic nasal bone deformities. Typically, tools such as chisels are used for osteotomies; however, we performed osteotomies using Kirschner wires without making a skin incision. Between April 2011 and July 2022, we performed rhinoplasty with external perforated osteotomy using Kirschner wires in 13 patients with post-traumatic nasal bone deformities (9 males and 4 females; mean age, 34 years, range 12-51 years), all of whom exhibited improvement, with only one case showing mild residual cosmetic deformity. None of the patients requested further revision, and all were satisfied with their functional results. The non-incisional external perforated technique is a reasonable method that allows for bone osteotomies along the fracture line and is well-controlled, predictable, and reproducible.

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.

Simultaneous Rhinoplasty and Septal Perforation Repair Using the Bone-Cartilaginous Unit.

BACKGROUND: Various techniques are employed for septal perforation repair but success rates still vary. Numerous mucosal flaps are used for septal perforation closure; however, a scaffold is essential for proper positioning and enhanced mucosal growth. OBJECTIVES: The aim of this study was to assess the effectiveness of utilizing a septal bone/cartilage composite graft (BC unit) to close septal perforations in rhinoplasty patients and evaluate patient satisfaction. METHODS: This case series included patients with septal perforation undergoing rhinoplasty and perforation repair between 2019 and 2023. BC units were used to cover the cartilaginous perforations in all patients. Patients were followed for a minimum of 1 year, assessing surgical results and postoperative satisfaction with the 10-item Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS). RESULTS: In this study, 31 patients (22 female, 9 male), with a mean [standard deviation] age of 34.80 [10.31] years (range, 19-59 years), were enrolled. Nine had previousl undergone septoplasty, while four had undergone septorhinoplasty. The preoperative perforation size ranged from 6 to 27 mm (mean, 14.1 mm). At final follow-up, 26 cases (83.8%) achieved complete closure, while 3 had incomplete closures, and 2 experienced reperforation. Analysis revealed a notable mean decrease of 31.93 [26.47] in obstruction domain scores (SCHNOS-O) and a mean decrease of 44.19 [25.37] in cosmesis domain scores (SCHNOS-C). CONCLUSIONS: Septal perforation repair and rhinoplasty can be safely and effectively performed concurrently with BC units for suitable candidates.

Naso-Orbital-Ethmoid Fracture Repair Techniques: A Systematic Review.

PURPOSE: Naso-orbital-ethmoid (NOE) complex fractures present a challenge to repair. The classification system used to categorize the fracture type was established in 1991 based off the medial canthal tendon attachment. The primary objective was to systematically review the literature outlining repair techniques for NOE fracture after the adoption of the Markowitz classification system. METHODS: A systematic search was performed in PubMed, Embase, and Web of Science to identify peer-reviewed research. Eligible studies were peer-reviewed articles reporting on operative techniques used to repair NOE fractures in adult patients after 1991. Two investigators independently reviewed all articles and extracted data. Level of evidence was assessed by Oxford Center for Evidence-based Medicine guidelines. RESULTS: This review identified 16 articles that met inclusion/exclusion criteria representing 517 patients. One article outlined a closed reduction technique with transnasal wiring. The remaining articles discussed open approaches with various exposure techniques, most common being the coronal incision. Miniplates and screws were most often implemented for rigid fixation as well as transnasal wiring to repair disrupted medial canthal tendon and canthal bearing bone in Type 2 and 3 NOE fractures. Ten of the studies included in this review had a level of evidence of 4. CONCLUSIONS: NOE fractures present a complex fracture pattern and challenge to repair. New exposure techniques and multidisciplinary approaches have been described. However, fixation techniques have remained relatively consistent through the years. Surgeon preference and comfort with performing the specific techniques leads to the best patient outcomes. With the low level of evidence referenced, more robust research is needed to evaluate these techniques.

The Fish Bone Technique: An Innovative Approach for the Bony Nasal Pyramid.

Among many contributions to the world of art and science, Renaissance artist Leonardo da Vinci created the technique known as sfumato. In this technique, da Vinci considered that the regions to be highlighted should be lit up, while the regions to be hidden should be darkened. Drawing parallel with the face, we can work on the anatomical structures underlying the skin and create a favorable surface anatomy for the entire face, including the nose. However, to achieve the ideal hourglass shape of the nose, the bones must be shaped, and a variety of osteotomies are described and used to achieve this. The new and innovative Fish Bone technique, described in this article, allows for the bony nasal pyramid to be shaped and adapted to the hourglass shape, resulting in a harmonious contour, with smooth transitions and preservation airway.

Aesthetic Outcomes of Rhinoplasty Performed in the Early Posttrauma Period after Nasal Bone Fracture.

The optimal timing of rhinoplasty for patients with nasal bone fractures remains controversial. We investigated whether the timing of rhinoplasty after nasal trauma affects the aesthetic outcome of the procedure. A total of 41 adult patients with nasal bone fractures who underwent rhinoplasty between 2006 and 2021 were enrolled in this study. A visual analog scale (VAS) was used to indicate the assessor's satisfaction with the surgical outcome after a comparison of the pre- and postoperative facial photographs of each patient. Of the 41 patients, 28 underwent rhinoplasty within 14 days after nasal trauma (early rhinoplasty group), whereas 13 underwent rhinoplasty more than 14 days after nasal trauma (late rhinoplasty group). The rate of receiving spreader and shield graft was higher in the late rhinoplasty group (p = 0.043 and 0.018, respectively). Patients with type IV or V nasal bone fracture and patients with preoperative saddle noses had higher VAS scores than those with types I to III fractures and those without preoperative saddle nose (p = 0.003 and 0.020, respectively). There was no significant difference in overall aesthetic outcome between the early and late rhinoplasty groups. Both groups achieved significantly better radix height, dorsal height, and tip projection after rhinoplasty. The aesthetic outcome of rhinoplasty performed in the early posttrauma period is comparable with that of rhinoplasty performed more than 2 weeks after nasal bone fracture. Rhinoplasty can be considered a safe surgical treatment option for nasal bone fracture, even in the early posttrauma period. LEVEL OF EVIDENCE: : 4.

Perfecting the Outcome of Nasal Bone Fracture in the Pediatric Population With a Navigation System.

BACKGROUND: The trend of using navigation systems for treating facial bone fractures is increasing. Nevertheless, any detailed recommendation on using a navigation system to treat nasal bone fracture has never been discussed. Plastic surgeons are prone to do closed reduction of nasal bone fractures with remnant posttraumatic edema in the pediatric population. This study hypothesized that the navigation system benefits this population's treatment of nasal bone fractures. METHODS: The authors evaluated the medical records, plain x-ray, and facial computed tomography scans of 44 pediatric patients (below the age of 18) with nasal bone fractures treated with a closed reduction from May 2021 to December 2022. Preoperative and postoperative computed tomography scan were used to assess the outcome. RESULTS: The average age for 44 pediatric nasal bone fracture patients was 10. Fifteen were female, while males were 29. All cases were successfully corrected clinically and radiologically without noticeable complications. CONCLUSIONS: Using navigation systems to correct nasal bone fractures provides additional benefits for the pediatric population. This technique is especially useful if the fracture is located at the junction between the nasal bone and nasal process of the maxilla and is combined with concurrent old nasal bone fractures.

Lateral Osteotomy for the Surgical Treatment of the Asian Wide Nose.

OBJECTIVE: Narrowing of the nasal dorsum allows for a more pleasing moderate width. We here introduce a lateral osteotomy technique that is less traumatic and easier to perform than commonly used procedures in Asian and share our experiences in the application. METHODS: After a blunt dissection of the periosteum at the mucosal side of the nasal bone, all patients who underwent treatment using nasal osteotomy at the level of the maxillary nasal process were retrospectively analyzed. The bony nasal width, height, and the nasal lateral wall slope of bone before and after surgery were measured. The postoperative outcomes, complications, and patient satisfaction were analyzed and evaluated. RESULTS: From January 2008 to January 2018, nasal dorsum narrowing was implemented in 106 patients. On average, nasal width was significantly decreased and no change in nose height after the nasal osteotomy. The nasal width was significantly reduced by 8.51 ± 2.16 mm compared with before surgery. The slope of the nasal lateral wall was reduced from the mean of 155.0 ± 7.63-degree preoperation to the mean of 135.25 ± 7.50-degree postoperation. The follow-up period ranged from 6 months to 4 years, with an average of 10.3 months. CONCLUSIONS: This type of nasal bone base osteotomy is a simple and feasible method for the treatment of wide Asian noses with a high patient acceptance and stable postoperative results. LEVEL OF EVIDENCE: Level IV.

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.

A Simple and Minimal Invasive Method in Reduction of Depressed Nasal Bone Fracture by Using a Foley Catheter Ballooning Technique.

The nasal bone fracture is the most common type of facial bone fracture. Closed reduction with metal reduction instrument is commonly conducted for the treatment of a type II nasal bone fracture. The authors defined a new catheter dilation technique and used it in patients with type II depressed nasal bone fractures. Preoperative and postoperative nasal appearance and radiologic examination of the patients were compared. There was a statistically significant improvement in the nasal appearance of all patients. No recurrence or dorsal irregularity has been observed. This new, easily applicable catheter dilation method of closed reduction may be a simple and less invasive solution to treat type II nasal bone fractures.

A Novel Balloon Catheter Dilation Apparatus for the Treatment of Depressed Nasal Bone Fracture.

The nasal bone fracture is the most common type of facial bone fracture. Closed reduction with metal reduction instrument is commonly conducted for the treatment of a depressed nasal bone fracture which often leads to iatrogenic injury. In this article, a new balloon catheter dilation apparatus for nasal bone fracture is hypothesized by the authors. This device aims to repair nasal bone fracture via dilated balloons under fractured nasal bone and used as nasal internal packing system after operation. Compared with the conventional approach, it is proposed that this balloon dilation apparatus could be a potential powerful, less invasive approach to treat depressed nasal bone fractures.

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.
