SUMMARY: The hypertrophied temporalis and masseter muscles give a muscular shaped and bulky contour to the face. Botulinum neurotoxin injection methods are commonly used for facial contouring; however, adverse effects have been reported owing to a lack of delicate anatomical information. The anatomical considerations when injecting botulinum neurotoxin into the temporalis and masseter muscles were reviewed in the present study. Current knowledge on the localization of the botulinum neurotoxin in

Hyaluronic acid filler injection is a minimally invasive procedure for facial rejuvenation that involves injecting filling materials to correct the volume or augment specific areas in the face. Deep nasolabial folds are a common concern in aging people. The simplest way to correct a deep nasolabial fold to rejuvenate the face is to inject Ristow's space with hyaluronic acid fillers. However, conventional injection methods, such as percutaneous injections using a needle, can cause severe complica

OBJECTIVE: To determine whether obesity influenced the risk of perioperative and long-term complications in patients undergoing vaginal surgery. METHODS: Women diagnosed with pelvic organ prolapse who underwent vaginal surgery between March 1999 and May 2007 were classified into 3 groups: normal weight (body mass index [BMI, calculated as weight in kilograms divided by the square of height in meters] 18.5-23.0); overweight (BMI 23.0-27.5); and obese (BMI >or=27.5). Complications were subdivided

This study aimed to identify ideal sites for botulinum toxin injection by analyzing the intramuscular nerve patterns of the triceps brachii muscles. A modified Sihler's method was applied to the triceps brachii muscle (15 specimens), with long, medial, and lateral heads. The intramuscular arborization areas of the long, medial, and lateral heads of the triceps brachii muscle were measured as a percentage of the total distance from the midpoint of the olecranon (0%) to the anteroinferior point of

5D LB is reproducible and comparable with conventional 2D and 3D ultrasound techniques for fetal long bone measurement.

To evaluate the distribution of fetal frontomaxillary facial (FMF) angle at in normal Korean population at 11 + 0 to 13 + 6 weeks gestation. Three-dimensional (3D) volumes of the fetal head were obtained from low risk singleton pregnancies at 11 + 0 to 13 + 6 weeks who consented to this prospective study. Only cases with either a normal karyotype confirmed on amniocentesis or delivered a normal live infant were considered eligible for analysis. Those with multiple pregnancies, fetal anomaly conf

=다빈치수술로봇시스템이 소개되어 전세계적으로 활발하게 외과분야에 적용이 되고 있다. 이러한 로봇수술시스템은 개발초기에 개심수술을 효율적으로 하기 위해 개발되었으나 다양한 장점으로 말미암아 외과, 비뇨기과, 산부인과, 흉부외과, 이비인후과 등에서 폭넓게 이용이 되고 있다. 더구나 부인과영역에서도 이에 대한 관심이 폭발적으로 증폭되면서 많은 부인과수술이 선진외국에서는 이루어지고 있으나 아직 국내에서는 자궁절제술을 다빈치로봇수술을 통해 진행된 경우가 전무한 상태이다. 이에 자궁경부상피내암환자를 대상으로 하여 국내에서 최초로 이루어진 로봇복강경하 전자궁절제술의 임상경험을 보고한다.

During pregnancy, exposure to fine particulate matter (PM2.5), particularly diesel exhaust particles (DEPs), elevates the risk of placental dysfunction-related pregnancy complications; however, the underlying cellular mechanisms have yet to be fully elucidated. The objective of this study was to assess the effects of PM2.5 exposure on trophoblast functions and their interaction with endometrial stromal cells. We utilized a three-dimensional (3D) model in which human first-trimester trophoblasts

To determine the performance of screening for preeclampsia by combining second trimester maternal serum screening and uterine artery Doppler ultrasound. A total of 876 women underwent both maternal serum screening (using α-fetoprotein (AFP), uE3, and human chorionic gonadotropin (hCG)), measurement of uric acid, and second trimester uterine artery Doppler ultrasound. The sensitivity, specificity and predictive value of different combinations of tests were compared. Of 876 pregnancies originally

Objective To evaluate the feasibility of five-dimensional Long Bone (5D LB), a new technique that automatically archives, reconstructs images, and measures lengths of fetal long bones, to assess whether the direction of volume sweep influences fetal long bone measurements in three-dimensional (3D) ultrasound and 5D LB, and to compare measurements of fetal long bone lengths obtained with 5D LB and those obtained with conventional two-dimensional (2D) and manual 3D techniques.

근육의 해부학적 구조는 복잡하고 세밀하게 얽혀 있어, 이를 이해하기 위한 교육 자료는 일러스트레이션, 3차원 모델, 온라인 콘텐츠 등 다양한 형태로 제공되고 있다. 기존 교육 자료들은 정보 전달에 중점을 두고 있으나, 학습자가 근육의 층별 구조를 직관적으로 이해하고 기억하는 데는 한계가 있다. 본 연구는 인체 근육의 위치와 입체적 구조를 효과적으로 이해할 수 있도록 지원하기 위해 재접착이 가능한 스티커를 활용한 체험형 교육 자료를 개발하는 것을 목표로 하였다. 개발된 교재는 A2 크기의 양면 뼈대 일러스트레이션 스티커 배경 1장과 A4 크기의 앞면 및 뒷면 근육 스티커 각 7장, 총 15장으로 구성되어 있다. 근육 일러스트레이션은 앞면 62개, 뒷면 65개를 포함하여 총 127개의 근육을 표현하고 있으며, 학습자는 제공된 알파벳 순서대로 근육 스티커를 뼈대에 맞는 위치에 부착하면서 학습을 진행한다. 교재에 적용된 근육의 개수가 많고 스티커의 형태가 정교하여 성인 이상의 학습자에게 적

Purpose: For minimally invasive procedures, three-dimensional (3D) anatomical knowledge of the structures of the face is essential. This study aimed to describe the thickness of the skin and subcutaneous tissue and depths of the facial muscles located in the infraorbital region using a 3D scanner to provide critical clinical anatomical guidelines for improving minimally invasive cosmetic procedures. Materials and Methods: The 3D scanning images of 38 Korean cadavers (22 males and 16 females; age
