Orthognathic surgery (OGS) using the surgery-first approach (SFA) can decrease treatment time and increase patient satisfaction. Clockwise rotation (CWR) of the maxillomandibular complex to correct mandibular prognathism leads to optimized functional, aesthetic, and stable outcomes. This study examined the combined effect of SFA and CWR of the maxillomandibular complex to correct mandibular prognathism by comparing the surgical movement before (T0) and immediately after OGS (T1) and the stability between T1 and 12 months after OGS (T2).This prospective cohort study enrolled patients with skeletal Class III malocclusion who underwent SFA involving Le Fort I osteotomy and bilateral sagittal split osteotomy, with or without genioplasty. Based on the occlusal plane (OP) change at T0-T1, the patients were divided into CWR (OP 4°) and control (C) groups (OP ≤ 4°). The predictor variable was OP change at T0-T1. The primary outcome variable was the stability of pogonion (Pog) at T1-T2. The covariates included demographic factors, cephalometric measurements (anterior facial height, posterior facial height, OP, mandibular plane angle, incisor mandibular plane angle, overjet, and overbite), and 3-dimensional landmark displacement (anterior nasal spine, A-point, upper central incisor, upper first molar, lower central incisor, lower first molar, Pog, gonion, and condylion). An independent t-test was used to compare between these 2 groups when appropriate. The level of significance was set at P .05.The sample included 28 patients (17 females) in the C group and 36 (24 females) in the CWR group; the mean ages were 23.89 ± 3.35 and 24.08 ± 4.02 years, respectively. For the surgical movement at T0-T1, the CWR group showed an association with vertical movement of the maxilla at posterior nasal spine (P = .005), anterior nasal spine (P .001), and A-point (P .001) and horizontal backward movement of the mandible at B-point (P .001), Pog (P .001), and gonion (P = .042). At T1-T2, all landmarks remained stable without clinically significant difference between the 2 groups.Surgical movement in the CWR group could vertically displace the maxilla and setback mandible more than that in the C group. Postoperative skeletal stability remained the same between the 2 groups at 1 year after OGS.

This study summarizes the process of digital-assisted multidisciplinary treatment (MDT) of naso-orbital-ethmoid (NOE) fractures and evaluates the treatment outcomes. From October 2018 to December 2020, 39 patients with NOE fractures were treated in our department, 21 of whom were diagnosed and treated by a multidisciplinary team. After preoperative multidisciplinary discussions and personalized virtual surgical planning, they received MDT with the assistance of a surgical navigation system. The other 18 patients received traditional single-disciplinary treatment, that is, no preoperative multidisciplinary discussions. Oral and maxil-lofacial surgeons performed surgical design and digitally-assisted surgery alone. After the operation, treatment outcomes were evaluated in terms of aesthetic appearance and function. The duration of preoperative preparation and postoperative aesthetic outcomes were not significantly different in patients who received single-disciplinary treatment and MDT ( P0.05). However, postoperative functional outcomes were significantly better in patients who received MDT ( P0.05). Furthermore, no significant complications were found. Digital-assisted MDT has a high application value in repair and appearance reconstruction, especially restoring functionality after NOE fracture; thus, it should be promoted in clinical practice.

Septoplasty and rhinoplasty are difficult operations to learn and teach. Many modalities have been proposed to make the teaching process of these operations easier. In this study, it was investigated if lamb heads were good training models to teach septoplasty and rhinoplasty to trainees or experienced surgeons. In the first part of the study, 21 lamb heads were dissected according to a dissection protocol and several anatomical distances were measured to compare them with human cadavers. In the second part, eight lamb heads were dissected and different preservation rhinoplasty techniques were practiced. The study on 21 lamb heads used showed that the lateral crura were 17.8 × 11.6, the average interdomal distance was 8.1 mm, and the average domal width was 3.7 mm. The average length of the upper lateral cartilages was 31.1 mm laterally and 21.2 medially. The average length of the nasal bones was 63.9 mm, and the width was 16 mm. In the second part of the study, 8 lamb heads were used to experience where high-strip techniques were used in 5 and the Cottle technique in 3. This study revealed that lamb heads should be considered as an excellent training model for septoplasty and rhinoplasty. Its very low cost, ease of availability, and close similarity to the human cadavers can be counted as the main advantages. This study also proved that it was not only a tool for beginners, but also a very helpful tool for experienced surgeons to try new methods. © 2022 Thieme Medical Publishers, Inc..

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.

Infants and toddlers can sustain grievous craniofacial injuries after dog bites, some of which may be life-threatening. An 18-mo-old male child presented to our emergency department with complex panfacial wounds after being bitten by an unvaccinated wild dog 6 h earlier. Primary management, hemostasis, and rabies postexposure prophylaxis were performed near his home. Initially, he was resuscitated from severe hemorrhagic shock and anemia in a pediatric intensive care unit. After stabilization, early primary repair of all facial injuries was performed. Surgical exploration revealed multiple full-thickness avulsions, lacerations, nasal bone fractures, facial muscle injuries, and right ear necrosis. Gentle tissue-handling and meticulous reconstruction satisfactorily restored his facial soft-tissue contours about 64 h after the bite injury. Postoperatively, recovery was uneventful except for localized soft-tissue infection caused by multidrug-resistant Pseudomonas, which resolved with appropriate antibiotics. Nine months later, his face and ear appeared almost symmetrical with well-settled scars. Psychological recovery progressed smoothly, excepting few incidences of panic attacks that were triggered by loud noises. Here, we observed that early primary reconstruction of severely mauled soft tissues after wild dog bites, performed within 72 h with adequate precautions, safely produced satisfying long-term outcomes.

Purpose of review The aim of this study was to present the evaluation and current management of congenital paediatric nasal dermoid. Recent findings There has been a trend towards less invasive surgical excision techniques, including purely endoscopic excision, endoscopic-assisted approaches and midline excision with nasal bone osteotomies and bone flap. These approaches allow adequate access for both total resection and nasal contour and skull base reconstruction. Following resection, if nasal bone osteotomies are insufficient for restoring nasal appearance, free temporoparietal fascial graft and/or conchal cartilage can be considered. For nasal tip deformities, interdomal sutures and free fat grafting are a suitable option. Summary Complete surgical excision remains the treatment of choice for nasal dermoid lesions. The surgical approach taken and reconstruction depends on the type of lesion (cyst versus sinus or fistula), location (intranasal versus extranasal), whether or not there is intracranial extension, and experience of the surgical team.

BACKGROUND Although it has been common to use artificial implant to augment nasal dorsum in Asian rhinoplasty, the demand for not using it is increasing due to the long-term complications of implants. However, if only the tip is raised without raising the dorsum with implant, it is difficult to avoid supratip depression, so it is difficult to obtain good cosmetic results. The authors would like to report good results, performing an augmentation rhinoplasty that raises the supratip area using the nasal septal cartilage without using an implant. METHODS Septal gap graft was used in 22 patients undergoing nasal tip surgery from January 2019 to April 2021. Septal gap graft refers to a graft that increases the height of the supratip area by using septal cartilage. Firstly, the authors perform a septal extension graft using the septal cartilage, then the authors fix the lower lateral cartilage in an ideal position, and lastly the authors heighten the nasal tip with onlay graft. The height difference between the nasal bone and the nasal tip, is solved by placing the septal cartilage. Before, during and after surgery, photometric analysis was done by taking clinical pictures. RESULTS Through the septal gap graft, the supratip depression index was decreased and the nasal tip projection was increased. It was confirmed that the septal gap graft was well maintained at long-term follow-up, and the patients' postoperative satisfaction was also high. CONCLUSIONS The authors presented a new technique for augmentation rhinoplasty in Asians. Septal gap graft can be used safely and effectively to raise supratip area without using implant.

Background Subdorsal septal resection and radix osteotomy are distinctive surgical steps in preservation rhinoplasty. Objectives The aim of this study was to evaluate the nasal bone thickness, the level of the septal bony-cartilaginous junction (K area), and the distances of the frontal sinus and skull base from the transverse osteotomy line in the Turkish population by means of conventional computed tomography (CT). Methods A retrospective evaluation was made of 203 consecutive preoperative paranasal CT scans of patients (classified in terms of age and gender) who had undergone rhinoplasty surgery between January 2020 and June 2021. The nasal bone thickness at the medial canthus level, and the distances between the transverse osteotomy line and the K area, the frontal sinus, and the cribriform plate were measured. Results The mean measurements were similar in terms of age groups (P = 0.402, P = 0.542, P = 0.134 and P = 0.276 for ages 18-30, 30-40, 40-50, and >50 years, respectively). The mean nasal bone thickness and the distance between the transverse osteotomy line and the K area showed statistical significance (P = 0.001 and P = 0.001, respectively). In both genders, the mean distances between the transverse osteotomy line and the frontal sinus and the cribriform plate were similar (P = 0.921 and P = 0.280, respectively). The nasal bone was thinner and the K area position more cephalic in females. Conclusions CT plays an important role in preoperative planning. The need for resection of the ethmoid perpendicular bone may be greater in males when lowering the dorsal hump, and hence they may be more prone to skull base complications. It is therefore necessary to be more careful in the surgical stage of subdorsal septal excision in males.

In this study we aimed to compare external lateral osteotomy technique vs. internal one in the rhinoplasty. In this before-after clinical trial study 30 patients who were candidates for rhinoplasty involved. In each patient, external lateral osteotomy was performed on one side and internal lateral osteotomy was performed on the other side randomly. Information, including patients’ age, sex, grade of edema and ecchymosis 1, 3, and 7 days after the surgery, and the type of lateral osteotomy, the amount of step deformity, the need for the specialist intervention, nasal bone mobility, and flail nasal bone was recorded and analyzed. The incidence of edema and ecchymosis on the first and the third day was statistically lower in the external method (P value 0.05). Forty seven percent of patients in the internal method and 36% of patients in the external method had step deformity (p value 0.05). Seventy four of patients in the internal method and 83% of patients in the external method had nasal bone mobility (p value > 0.05). Out of 30 patients, only one had flail nasal bone. Based on our findings, the external technique is suggested as a more effective and convenient method with less complications for inexperienced surgeons.

Objectives When performing cosmetic rhinoplasty with alloplastic materials, complications such as implant visualization, inflammation, dislocation, and extrusion should be thoroughly evaluated. Although computed tomography (CT) can give us useful information about the implant status and its interaction with the skin soft tissue envelop (SSTE), radiologic findings of these interactions have rarely been reported. Methods We retrospectively reviewed the data of eighty patients who underwent facial bone CT or ostiomeatal unit (OMU) CT at the Asan Medical Center between July 2008 and January 2020 for the evaluation of complicated dorsal implants. We reviewed the implantation period, implant dislocation, implant curling or deformation, Hounsfield unit (HU), and nasal bone changes including bone erosion or hyperostosis. Results Of the 80 patients, 67 (83.8%) patients had silicone implants and 13 (16.2%) patients had Gore-Tex implants. The radiologic findings of the silicone implants were as follows: maintained implant shape (80.6%), radiolucent (similar density to that of fat tissue) halo (83.6%), homogenous attenuation (82.1%). Peri-implant calcification was often found in silicone implants with >20-year implantation periods. Those of Gore-Tex were as follows; curling or deformation (84.6%), heterogeneous attenuation (84.6%), and in terms of peri-implant calcification, there was no tendency of change over time. Conclusion The silicone and Gore-Tex implants have distinctive radiologic features. These findings of alloplastic materials help us to know how the implant behaves in the nasal dorsum and how it affects the SSTE.

To evaluate the effect of vomer position and prevalence of periodontal dehiscence in patients who underwent surgically assisted rapid palatal expansion (SARPE). The null hypotheses were the following: (1) vomer position in the coronal plane does not influence the degree of skeletal and dental expansion; and (2) there is no association between expansion, periodontal dehiscence and vomer position. Twenty-one patients were evaluated before treatment (T0) and immediately after SARPE expansion (T1). After SARPE, the vomer was in the right side in 11 patients and in the left in 10 patients. Skeletal and dental effects were evaluated using CBCT, landmarks and measurements. The maxilla and the nasal cavity expanded asymmetrically. The side containing the vomer had less skeletal expansion but more dental tipping. Dehiscence increased significantly from T0 to T1 and was associated with the amount of skeletal displacement, especially when greater than 3.20 mm. In the first premolars region, there was more than 2 mm of asymmetric expansion observed in 38.5% of the patients. The null hypotheses were rejected. The side containing the vomer had less skeletal expansion of the maxilla and nasal cavity but more dental tipping. Dehiscence increased after expansion, but there were no differences between sides.

A rhinoplasty technique involving lower lateral cartilage (LLC) repositioning and grafting of ear cartilage allows for nasal lengthening and nasal tip mobility. For better esthetic outcomes in patients with cleft lip nasal deformity (CLND), we combined cosmetic nasal tip plasty with standard techniques. We performed open rhinoplasty combined with reverse-U incision and V-Y plasty in 62 patients with secondary unilateral CLND from October 2013 to June 2018. Both LLCs were isolated, repositioned, approximated medially, and advanced with a Medpor strut, followed by tip suture technique. To further project and enhance the nasal tip and columella, application of ear cartilage onlay graft was used. As adjunctive procedures, septoplasty or osteotomy was carried out for correction of septal or nasal bone deviations, respectively. Photogrammetric evaluations of patients and statistical analyses were performed. Average age at operation was 23.5 years (range: 18-42 years). Of the 62 patients, 15 underwent dorsal augmentation with silicone implant. Two-layer conchal cartilage onlay grafting was performed to manage tip height. Outcomes in 34 patients were analyzed with pre- and postoperative photography. Nasal tip projection increased, alar base width index decreased, and alar and columellar symmetry significantly improved. No Medpor implant exposure or other adverse outcomes occurred. The proposed technique is effective for correcting secondary unilateral CLND and achieving a satisfying nasal appearance in adults.

BACKGROUND Pediatric nasal fractures, unlike adult nasal fractures, are treated surgically as early as 7 days after the initial trauma. However, in some cases, a week or more elapses before surgery, and few studies have investigated the consequences of delayed surgery for pediatric nasal fractures. The purpose of this study was to evaluate the postoperative outcomes of pediatric nasal fractures according to the time interval between the initial trauma and surgery. METHODS The records of pediatric patients under 12 years old who underwent closed reduction of nasal bone fracture from March 2012 to February 2020 were reviewed. The interval between trauma and surgery was divided into within 7 days (early reduction) and more than 7 days (delayed reduction). Postoperative results were classified into five grades (excellent, good, moderate, poor, and very poor) based on the degree of reduction shown on computed tomography. RESULTS Ninety-eight patients were analyzed, of whom 51 underwent early reduction and 47 underwent delayed reduction. Forty-two (82.4%) of the 51 patients in the early reduction group showed excellent results, and nine (17.6%) showed good results. Thirty-nine (83.0%) of the 47 patients in the delayed reduction group showed excellent results and eight (17.0%) showed good results. No statistically significant difference in outcomes was found between the two groups (chi-square test p= 0.937). However, patients without septal injury were significantly more likely to have excellent postoperative outcomes (chi-square test p< 0.01). CONCLUSION No statistically significant difference was found in the outcomes of pediatric nasal fractures between the early and delayed reduction groups. Successful surgical results were found even in patients who received delayed reduction (more than 7 days after trauma).

The etiology of maxillofacial fractures (MFFs) varies according to the geographical location and density of the population. This study aimed to analyze the etiology, pattern, and treatment of MFFs. Epidemiological characteristics and treatment modalities of MFFs have never been evaluated in Somalia. The study included 45 patients who were operated on for MFFs at a tertiary care hospital in Somalia (2018-2019). Patient demographics, fracture causes, types, associated non-facial injuries, treatment modalities, and hospitalization-time were evaluated. The most common etiological factors of the MFFs were explosion (24.4%) and assault (24.4%), followed by gunshot (22.2%), sports accident (15.6%), motor vehicle accident (11.1%), and fall from height (2.2%) patients, respectively. The main site of injury was the mandible bone (64.4%) followed by nasal bone, maxilla, zygomatic, and orbital region. The most common non-facial injuries of the MFFs were soft tissue laceration (37.8%) followed by femoral fracture (6.7%), clavicle fracture (4.4%), and femoral fracture with chest injuries (2.2%). The most applied treatment was open reduction microplate +/- intermaxillary fixation (77.8%). Due to the size of the mandible fractures, an iliac autograft (6.7%) was performed. The mean length of the hospital stay was 11.8 ± 8.4 days (range, 1-45 days), and some patients (15.6%) needed intensive care due to severe injuries. This will be the first study aiming to analyze the etiology, pattern, and treatment of MFFs in Somalia. This study deals with the social aspects of Somalia, and it shows that MFFs develop as a result of highly interpersonal violence in a young man.

This study was conducted to investigate the effectiveness of closed reduction of nasal bone fracture according to severity. It was a retrospective study carried on 60 patients with mean age of 30.2 years (range 10-67 years) who have undergone a closed reduction of a nasal bone fracture at Gandaki Medical College Teaching Hospital from January 2017 to December 2019. The patient with nasal bone fracture who underwent surgical intervention with closed reduction under General anaesthesia were included in this study. Fracture severity was evaluated according to Hwang et al.’s classification method. All patients underwent closed reduction with external nasal splinting under General anesthesia. The patients were followed-up for at least three months to assess the complications, such as fracture recurrence and functional abnormality in the Department. The most common cause of nasal bone fracture was road traffic accidents 25 (41.6%) followed by physical assaults 18 (30%), fall injuries 12 (20%), other incidences 3 (5%), and industrial accidents 2 (3%). Forty-three (72%) cases underwent closed reduction within 24 hours of those who arrived within 4-6 hour of nasal injury in the hospital and the remaining 17 (28%) cases were reduced after 5 days of trauma. Concurrent fracture found in 8 (13%) cases and it included maxillary, zygomatic, orbital, frontal bone fracture. Nasal bone fracture mostly occurs in road traffic accidents. Closed reduction with good alignment is the preferred method. Septorhinoplasty and extracorporeal septoplasty should be applied in difficult and comminuted nasoseptal fracture.

Introduction Aesthetic rhinoplasty remains a challenging procedure with high expectations and narrow tolerance for errors. Considerable training is required to achieve controlled and reliable results. Use of the Piezotome is gaining popularity for performing the nasal osteotomies, a key step in rhinoplasty, where it is reported to improve precision and predictability and to keep tissue damage to a minimum. We compare the outcomes of conventional osteotomy techniques to piezosurgery in human cadavers as undertaken by surgical trainees. Materials and methods Seven human cadavers were used and a total of 14 osteotomies were performed. Conventional osteotomies and piezosurgery were carried out each on one side of the cadaver. A number of fragments and a blinded assessment of the accuracy of the osteotomy compared with the preprocedure skin markings were carried out by two experienced rhinoplasty surgeons. The Mann–Whitney test for statistical analysis was used. Results The mean number of fragments was 1.57 in the piezosurgery osteotomy and 2.14 using conventional osteotomies. Four of seven piezosurgery osteotomies achieved an accuracy within 1mm. The conventional osteotomies as performed by the trainees showed a significant mismatch of more than 3mm in three of seven of cases. Accuracy within 1mm was achieved in one of seven cases. Discussion Piezosurgery offers a safe, reliable and precise method of performing lateral nasal osteotomies. This human cadaver study shows a high accuracy of osteotomy and fewer comminuted fractures using this technique compared with conventional osteotomy techniques.

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.

Morphologic and anatomical changes of the aging nose affect the surgical strategy of rhinoplasty in older patients, but age-related changes in noses have yet to be fully characterized. This study aimed to determine the evolution of nasal soft tissue and bone in aging noses using computed tomography.Computed tomographic images of 200 Asian patients were included. The study population was divided into two groups according to age and sex: a younger group (20 to 35 years of age) and an older group (65 to 80 years of age). Measurements of nasal soft tissue and bone on computed tomography were performed using Osirix 9.0 software.With regard to soft-tissue changes, the nasal skin and soft-tissue envelope thickness at rhinion, supratip, and nasal tip increased significantly with aging in both sexes. Increase of nasal depth and decrease of nasolabial angle were significant in both sexes. Nasal length and nasofrontal angle showed significant age-related increases in men; decrease of nasal tip angle and increase of pyramidal angle were significant in women. With regard to nasal bone changes, the bone length decreased significantly in women and the bone thickness decreased significantly in both sexes. Nasofrontal angle in men and pyramidal angle in women increased significantly.These results suggest that the aging process leads to drooping of the nasal tip, thickened nasal skin and soft tissue, and resorption of the nasal bone, providing a reference for rhinoplasty in older patients.
