Altered cortical thickness of the superior frontal gyrus and fusiform gyrus in individuals with subthreshold social anxiety.

Subthreshold social anxiety (SSA) is a condition in which individuals experience social anxiety that does not reach the threshold required for a clinical diagnosis of a social anxiety disorder (SAD). Although SSA may not impair lives as severely as SAD, it can affect social functioning. However, only a few studies focused on structural neural correlates of SSA.

Asymmetric nasomaxillary expansion induced by tooth-bone-borne expander producing differential craniofacial changes.

Objectives: To evaluate three-dimensional (3D) craniofacial changes induced by a non-surgical tooth-bone-borne rapid palatal expander (TBB-RPE) according to the symmetrical pattern of expansion, to investigate the 3D changes between the sides in patients with asymmetric expansion, and to identify the related factors of asymmetric expansion.

Setting And Sample Population: Sixty-six patients (mean age: 19.3 ± 5.

Targeted presurgical decompensation in patients with yaw-dependent facial asymmetry.

Facial asymmetry can be classified into the rolling-dominant type (R-type), translation-dominant type (T-type), yawing-dominant type (Y-type), and atypical type (A-type) based on the distorted skeletal components that cause canting, translation, and yawing of the maxilla and/or mandible. Each facial asymmetry type represents dentoalveolar compensations in three dimensions that correspond to the main skeletal discrepancies. To obtain sufficient surgical correction, it is necessary to analyze the main skeletal discrepancies contributing to the facial asymmetry and then the skeletal-dental relationships in the maxilla and mandible separately.

Natural Head Postures of Patients With Facial Asymmetry in Frontal View Are Corrected After Orthognathic Surgeries.

Purpose: Although orthognathic surgeries focus on adjustment of facial asymmetry (FA), many clinicians know by experience that the natural head posture (NHP) also is corrected after the surgery. The authors examined whether this was indeed the case by the measuring the NHP during the course of orthognathic treatment. Factors associated with NHP correction also were evaluated.

Paraplegia following intercostal nerve neurolysis with alcohol and thoracic epidural injection in lung cancer patient.

The goal of cancer treatment is generally pain reduction and function recovery. However, drug therapy does not treat pain adequately in approximately 43% of patients, and the latter may have to undergo a nerve block or neurolysis. In the case reported here, a 42-year-old female patient with lung cancer (adenocarcinoma) developed paraplegia after receiving T8-10 and 11(th) intercostal nerve neurolysis and T9-10 interlaminar epidural steroid injections.

Preliminary three-dimensional analysis of tooth movement and arch dimension change of the maxillary dentition in Class II division 1 malocclusion treated with first premolar extraction: conventional anchorage vs. mini-implant anchorage.

Objective: This study aimed to compare the effects of conventional and orthodontic mini-implant (OMI) anchorage on tooth movement and arch-dimension changes in the maxillary dentition in Class II division 1 (CII div.1) patients.

Methods: CII div.

Three-dimensional mandibular change after sagittal split ramus osteotomy with a semirigid sliding plate system for fixation of a mandibular setback surgery.

Objective: This study proposes a new plate system, a sliding plate, after sagittal split ramus osteotomy (SSRO). The sliding plate was designed to adjust the spatial relationship between the proximal and distal segments during the postoperative period. This plate was used for mandibular setback surgery to minimize forward early relapse.

Bilateral pneumothoraces, pneumomediastinum, pneumoperitoneum, pneumoretroperitoneum, and subcutaneous emphysema after percutaneous tracheostomy -A case report-.

We report a rare case of a 72-year-old female who developed extensive subcutaneous emphysema, bilateral pneumothoraces, pneumomediastinum, pneumoperitoneum, and pneumoretroperitoneum after a percutaneous dilatational tracheostomy. The patient's T-cannula was accidentally connected to the oxygen line with a non-perforated connector. The patient rapidly developed respiratory insufficiency and subcutaneous emphysema in the neck and both shoulders.

Aloe-induced toxic hepatitis.

Aloe has been widely used in phytomedicine. Phytomedicine describes aloe as a herb which has anti-inflammatory, anti-proliferative, anti-aging effects. In recent years several cases of aloe-induced hepatotoxicity were reported.

Sagittal split ramus osteotomy with mandible reduction.

Background: The sagittal split ramus osteotomy is a well-established procedure, and many authors have attempted various modifications of the surgical technique. Nowadays, it is widely acknowledged that people in Korea, Japan, and China prefer an oval face, the lower part of which is slender. Therefore, among facial contouring procedures, the mandible reduction procedure is the most popular procedure in these countries.

Three-dimensional mandible reduction: correction of occlusal class I in skeletal class III cases.

Background: The human face is a three-dimensional structure. However, many studies on mandible reduction procedures are based on a two-dimensional concept, with a particular focus on one dimension: the width of the lower face. Many Korean individuals have class I occlusion with a skeletal class III pattern.

Determinants of successful treatment of bimaxillary protrusion: orthodontic treatment versus anterior segmental osteotomy.

The purpose of this study was to investigate the differences in initial skeletal, dental, and soft tissue characteristics of bimaxillary protrusion (BP) patients to determine poor or good results with orthodontic treatment (OT) or anterior segmental osteotomy (ASO) with extraction of four first premolars. Lateral cephalometric radiographs of 46 adult Korean females with BP were analyzed before treatment (T0) and after treatment (T1). According to the measurements at T1, patients were classified into group 1 (poor result with OT, n = 12), group 2 (good result with OT, n = 11), group 3 (poor result with ASO, n = 5), and group 4 (good result with ASO, n = 18).
