Twelve-Year Experience With Nasofrontal Angle (Radix) Augmentation in Rhinoplasty
This study aimed to describe the techniques of rhinoplasty, different materials used in the procedure, and results of at least 1 year of follow-up in our 12-year experience in this field. The authors retrospectively reviewed the data of patients who underwent rhino-plasty/septorhinoplasty with radix augmentation performed by 1 of the authors (a senior surgeon at our institution) using different graft materials, between January 2007 and December 2019. Patients younger than 18 years or who were followed up for less than 1 year were excluded from the study. In total, 387 patients (235 [60.7%] female; age range, 19–39 years)...

Collaborative Control Method and Experimental Research on Robot-Assisted Craniomaxillofacial Osteotomy Based on the Force Feedback and Optical Navigation
Objective:
Surgical robot has advantages in high accuracy and stability. But during the robot-assisted bone surgery, the lack of force information from surgical area and incapability of intervention from surgeons become the obstacle. The aim of the study is to introduce a collaborative control method based on the force feedback and optical navigation, which may optimally combine the excellent performance of surgical robot with clinical experiences of surgeons.
Materials and Methods:
The CMF ROBOT system was integrated with the force feedback system to ensure the collaborative control. Force-velocity control algo...

A Look Back: A Single Surgeon’s Experience Using Virtual Surgical Planning in Adult Orthognathic Surgery
This study evaluates a single surgeon’s experience with this technology over the past 6 years. Patients undergoing orthognathic surgery using VSP with the senior author between 2015 and 2021 were retrospectively reviewed. Virtual surgical planning –specific data including incidence of midline/cant correction, occlusal equilibration, serial splints, segmental osteotomies, and custom plates were recorded and analyzed. Sixty patients undergoing orthognathic surgery using simulated VSP in the study period were retrospectively reviewed. Mean age at time of surgery was 23.5±7.9 years. Forty-nine patients (81.7%) underwent L...

Preoperative Arterial Coil Embolization for Temporomandibular Joint (TMJ) Surgery in Children with TMJ Ankylosis
Abstract:
Temporomandibular joint (TMJ) ankylosis in children can alter facial development and affect oral hygiene and function. Surgical release of the ankylosis is the mainstay of treatment. The authors hypothesize that preoperative arterial coil embolization is safe and effective in preventing major blood loss during TMJ surgery (loss prompting blood transfusion or hemodynamic instability requiring vasoactive medication administration) in children with TMJ ankylosis.

The Effect of Arch Cartilage Graft and Tajima Reverse U Approach in the Secondary Reconstruction of Unilateral Cleft Lip Nasal Deformity
Abstract:
Secondary cleft lip nasal deformity is complicated with wide spectrum of defect and varied reconstructive procedures. There has been no unanimous solution for a given problem. In case of a localized alar depression in unilateral cleft lip nasal deformity, the conchal cartilage applied as arch graft was proposed. Patients were recruited from database of craniofacial center who received Tajima method and arch cartilage graft. Inclusion criteria were patients with unilateral cleft lip nasal deformity after skeletal maturity. Through a reverse U incision, the lower lateral cartilage was dissected and released fro...

Introduction of Digital-Assisted Multidisciplinary Treatment in the Functional and Morphological Reconstruction of Naso-Orbital-Ethmoid Fractures
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...

Intraoral Open Reduction for Mandibular Angle Fracture Using an Angulated Screwdriver System
Objectives:
The optimal surgical technique to treat a mandibular angle fracture remains a subject of debate. The authors introduce a new surgical technique, involving the use of an angulated screwdriver to treat mandibular angle fractures. This renders the intraoral approach both feasible and reliable, with fewer complications than with an external approach.
Methods:
Between January 2012 and March 2016, the authors used an angulated screwdriver to treat 24 patients with mandibular angle fractures via transoral open reduction and rigid fixation. Patients were divided into 2 groups, a favorable and an unfavorable ...

Application of Segmented Template in Three-Dimensionally Guided Mandibular Angle Osteotomy
Conclusions:
The custom-made template can guide the osteotomy plane during the MAO procedure and achieve favorable accuracy and symmetry. Direct contact of the saw with the guidance template not only facilitates control of the osteotomy line but also the oblique angle of the osteotomy plane. This methodology may be a feasible and effective tool for mandibular contouring. (Source: Journal of Craniofacial Surgery)

Custom Plates in Orthognathic Surgery: A Single Surgeon’s Experience and Learning Curve
Conclusions:
Patient-specific cutting guides and custom plates allow for precise spatial positioning of the osteotomized jaw in the orthognathic surgery. Unsurprisingly, obstacles must be overcome in adopting this new technology; here, we outline our experience and technical modifications that have resulted in increased surgical efficiency with comparable outcomes.

Uncovering the Pathogenesis of Orofacial Clefts Using Bioinformatics Analysis
Conclusions:
Bioinformatics methods were used to analyze OFC- related genes in this study, including hub gene identifying and analysis, protein – protein interaction network construction, and functional enrichment analysis. Several potential mechanisms related to occurrence of OFCs were also discussed. These results may be helpful for further studies of the etiology of OFC. (Source: Journal of Craniofacial Surgery)

Three-Dimensional Changes in the Mandibular Proximal Segment After Using a Surgery-First Approach in Patients With Class III Malocclusion and Facial Asymmetry
This study was performed to evaluate condylar position and angulation after asymmetric mandibular setback between a conventional (CA) and surgery-first approach (SFA) using three-dimensional analysis. The condylar positions of 30 patients with skeletal Class III malocclusion and facial asymmetry who underwent 1-jaw (sagittal split ramus osteotomy) or 2-jaw orthognathic surgery (Le Fort I osteotomy and sagittal split ramus osteotomy) with CA (n = 18) or SFA (n = 12) from 2 university hospitals were studied. The three-dimensional assessment of condylar changes was performed using computed tomography images at the initial tim...

Attractive Versus Golden Ratios: Formula of Utopian Beauty through Comparison of Facial Proportions among Worldwide Celebrities and Average People
Introduction:
Beauty criteria change according to trends, cultures, and expectations. So, the golden ratios are not enough to understand the actual beauty concept.
Objective:
It is aimed to create a method and formula to define beauty in terms of different facial measurements and ratios as variables.
Methods:
Frontal view photographs of 50 celebrities and 50 volunteers (female [n = 70] and male [n = 30]) were obtained. Thirty-three specific facial points were used. Fifty-nine measurements of distances between those points and ratios of those distances are used as statistical variables. Mean values of thos...

A Useful Tool for Various Problems in Nasal Tip: The Cephalic Transdomal Suture
Abstract:
Surgical manipulation of the nasal tip is a critical point in functional and aesthetic rhinoplasty procedure. Cephalic strip excision from the lower lateral cartilages, elongation or shortening the caudal septum, structural grafting for supporting the medial and lateral crura are major structural moves in building a durable cartilaginous framework. However, it is suture techniques that make up the final touch in fine tuning of the shape, projection, definition, and angulation (rotation) of the nasal tip over this framework.
Problems with fine-tuning of the nasal tip include inadequate or excessive definiti...
