The present paper was conducted to a systematic method of surgical guide for dental implant based on computer-aided technology through CT data and dental-cast data. By analyzing the patient's CT data, the implant region was planned using image processing techniques. For the specified implant region, the computer-aided method for the rational allocation of dental implant was addressed in a sense of anatomy. With biomechanical principles as well as aesthetical and functional requirements as preconditions, this method can make full use of bone quantity and quality to produce the optimum implantation axis. The transferring of implant planning to the patient was then realized by registration between CT models and dental-cast models. A case research explained the whole process of the surgical guide. The results validated the correctness and feasibility of this method, which has a great significance to enhance the quality and accuracy of implant surgery.

BACKGROUND Pediatric sinonasal tumors are rare, accounting for about 4% of all pediatric head and neck neoplasms. Due to their nonspecific symptoms such as nasal obstruction, epistaxis, and facial pain, these tumors often present diagnostic challenges and lead to delays in managment. Early and accurate diagnosis is crucial to optimize clinical outcomes.

Background: The liver cone unit (Tokyo 2020 terminology) of the peripheral portal vein territory represents the smallest anatomical and functional unit of the liver. While this unit enables anatomical, subsegmental resection, particularly in patients with cirrhosis, the tumor-bearing cone unit can be challenging to identify intraoperatively. PATIENTS AND METHODS: A 58-year-old man with hepatitis C-related cirrhosis (Child-Pugh B) was diagnosed with a subcapsular hepatocellular carcinoma (HCC) in segment 8.

Thoracic surgeons utilizing minimally invasive techniques for lung nodule resection often rely on localization markers to determine precise nodule location intraoperatively. Transbronchial or transthoracic injection of indocyanine green (ICG) dye has become a popular technique. However, surgery must be performed immediately as dye will dissipate to surrounding tissue.

Background And Aims: Ultrasound-guided deep serratus anterior plane (SAP) block has recently gained popularity as an analgesic technique in breast surgery. However, the effectiveness of ultrasound depends largely on the quality of the equipment used, and the technique can be complicated by patient-related factors such as obesity. We hypothesized that the simpler open approach to deep SAP block would be non-inferior to the ultrasound-guided approach in providing analgesia for modified radical mastectomy.

Background: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has emerged as an effective therapy for Meige syndrome (MS). However, the optimal stimulation site within STN and the most effective stimulation fiber tracts have not been investigated.
Methods: Based on the discovery cohort (n = 65), we first identified the optimal stimulation site within the STN using the sweet spot mapping method.
