안면윤곽술 Facial Bone Contouring

[BACKGROUND] Expansion of the aesthetic treatment armamentarium with novel injectable products has greatly improved our ability to reshape and enhance the facial profile. However, full-face "profiloplasty" with injectables remain a nascent …

[INTRODUCTION] Botulinum toxin type A causes muscle paralysis and is widely used in the masticatory muscle for stomatognathic diseases, such as temporomandibular disorder, bruxism, or masseteric hypertrophy. Nonetheless, its muscular effect…

The severe gummy smile and a skeletal class II profile pose challenges in treatment. This case report outlines an effective alternative for addressing these problems in a patient with skeletal class II division 2, class II molar relationshi…

[BACKGROUND] The standard procedure for managing skeletal class III malocclusion is maxillary advancement with mandibular setback. Occlusal plane-altering orthognathic surgery, such as jaw rotation, is useful as well. Although clockwise jaw…

Genioplasty is a widely used surgical approach to address chin deformities by performing an osteotomy on the inferior border of the mandible to allow for comprehensive repositioning of the chin. This study aimed to compare the accuracy of f…

Amelogenesis imperfecta refers to a group of hereditary diseases that affect dental enamel, often leading to a wide range of clinical manifestations and aesthetic concerns. This case report describes a female patient diagnosed with amelogen…

The aim of this study is to analyze the process of metamorphosis of a tall and ugly woman through plastic surgery as depicted in The Life and Loves of a She-Devil (1983) of Fay Weldon. The process of plastic surgeries and the psychology of …

[PURPOSE] This study evaluated the methods and clinical effects of multidisciplinary collaborative treatment for occlusal reconstruction in patients with old jaw fractures and dentition defects. [METHODS] Patients with old jaw fractures an…

[BACKGROUND] Hypertrophied submandibular glands provide a bulky contour to the lower face. Botulinum neurotoxin injection methods are commonly used for facial contouring; however, no studies have suggested injection points because of the la…

This study aimed to compare the smile's attractiveness in patients submitted to the treatment of gummy smiles with botulinum toxin or maxillary impaction surgery. The retrospective sample comprised 26 patients divided into two groups: Group…

Segmental maxillary osteotomy, a surgical technique used in orthognathic surgery, involves the risk of palatal mucosa tearing, which can lead to severe complications. Herein, we report the case of a woman with Angle class II malocclusion wh…

[PURPOSE] Despite the vast literature on submental liposuction, there are few studies describing its simultaneous association in orthognathic surgery. This systematic review aimed to evaluate the available evidence on the effectiveness of t…

In patients with cleft lip and palate the most common associated dental problem is lateral incisor agenesis, often associated with lack of support and definition of the nasal tip. In many cases, adhesions deriving from surgical procedures a…

[BACKGROUND] This in vitro study compared the stability of different fixation method combinations for the zygomatic complex after simulated L-shaped osteotomy reduction malarplasty, a common facial contouring surgery in East Asia with high …

[BACKGROUND] Overdevelopment of zygomatic bones often results in protrusion and flaring of the midfacial region. This makes the face appear squarer than the more favorable oval shape. Therefore, zygoma reduction surgery has become a commonl…

[PURPOSE OF REVIEW] The use of piezoelectric instrumentation is increasingly recognized as an alternative to traditional bone-cutting techniques across a wide array of surgeries. Here, we provide an overview of the technique, including devi…

[BACKGROUND] Based on a three-dimensional (3D) orthognathic simulation, this technical report introduces a method for augmentation genioplasty using a proximal bone fragment of the mandible, which is typically discarded in intraoral vertica…

Facial contouring relates to hard and soft structures that make up the face. Skeletal class II and III subjects present bone structure and position changes, significantly impacting the soft tissues. This study aims to analyze the morphology…

Among the accuracy analysis techniques for orthognathic surgery, regional voxel-based registration (R-VBR) has robust data, but remains unvalidated for smaller jaw segments. The purpose of this study was to validate the angular accuracy of …

Parry-Romberg syndrome (PRS) is a rare neurocutaneous and craniofacial disorder characterized by progressive hemifacial wasting and atrophy that predominantly affects children and young adults, with an estimated prevalence of 1 in 700,000 i…
