conclusions in our conditions, the use of an anatomical landmark-guided procedure was the preferred treatment method due to limited resources and a lack of adequate training. background central venous cannulation is a current and important procedure used in the operating room and intensive care unit. some studies have shown that the application of ultrasound-guided cannulation can improve the s...

The Effects of Ultrasound-guided and Anatomic landmark-based Superficial Cervical Plexus Block on Post-operative Pain Intensity in Thyroidectomy Patients: A Clinical Trial

AIM To compare the traditional anatomic landmark technique with the ultrasound-guided method for central venous catheterization. MATERIAL AND METHODS During three years, 551 patients underwent internal jugular vein catheterization; in 347 patients, the ultrasound-guided technique was used, while in the other 204 patients the catheter was introduced by using the classical anatomic landmark met...

Perioperative navigation is an upcoming tool in orthognathic surgery. This study aimed to access the feasibility of the technique and to evaluate the success rate of 3 different registration methods--facial surface registration, anatomic landmark-based registration, and template-based registration. The BrainLab navigation system (BrainLab AG, Feldkirchen, Germany) was used as an additional prec...

Innovations in laser technology have led to the development of three-dimensional surface laser digitisation techniques capable of registering surface topology accurately. The clinical application of this technology in cleft palate documentation requires validation of the technique. This study determined the reliability of the surface laser scanning technique and assessed the reliability of inte...

The aim of this study is to examine the influence threshold-based segmentation on mean error automatic landmark detection in 3D CBCT images. A GUI was developed for radiologists, allowing manual identification and visualization After a segmentation, semi-automatic algorithm designed using anatomic definition each landmark. step 50 Hounsfield units used threshold variation assess error. 5 images...

OBJECTIVE To assess senior and junior anaesthetists' ability to locate the right and left jugular vein (IJV) using the anatomic landmark technique. METHODS A total of 45 anaesthetists were included in this study. Initially, a questionnaire assessing the experiences of the anaesthetists was completed. The anaesthetists were grouped into two groups, junior and senior. The anaesthetists, who wer...

BACKGROUND AND PURPOSE No validated imaging landmark exists for characterizing the medial-lateral position of abnormalities at the high convexity-parasagittal region. Our understanding of the courses and deflections of the upper cerebral sulci is limited. Our purpose, therefore, was to define a frontooccipital line with reproducible anatomic relations to the upper cerebral gyri and sulci and to...
