OBJECTIVE Pedicle screw fixation is a technique widely used to treat conditions ranging from spine deformity to fracture stabilization. Pedicle screws have been used traditionally in the lumbar spine; however, they are now being used with increasing frequency in the thoracic spine as a more favorable alternative to hooks, wires, or cables. Although safety concerns, such as the incidence of adjacent-segment disease (ASD) after cervical and lumbar fusions, have been reported, such issues in the thoracic spine have yet to be addressed thoroughly...

Three-dimensional (3D) visualization technology in pancreatic head cancers could offer decision-making support to preoperative diagnosis, resectability assessment and individualized surgical planning. In addition, the pancreas 3D printing helps to realize the leapfrog development from 3D images to 3D physical models and provides better guidance of the precise surgery of complicated cancers of the pancreatic head. In order to standardize the application of 3D visualization and 3D printing technology in the diagnosis and treatment of pancreatic head cancer, Chinese experts in relevant fields were organized by four committees to formulate this expert consensus...

Intrathoracic paragangliomas are uncommon and only represent 1%-2% of paragangliomas. They are most commonly found in mediastinal compartments (aortopulmonary window or posterior mediastinum). Computed tomography, magnetic resonance, and specific nuclear medicine radiotracers are routinely used to characterize these lesions and help exclude other more common conditions. Selective angiography is currently used for preoperative embolization and mapping of the vascular supply before surgical resection, rather than for diagnostic purposes alone...

Although the electrocardiograph (ECG) was invented more than 100 years ago, it remains the most commonly used test in clinical medicine. It is easy to perform, relatively cheap, and results are readily available. Interpretation, however, needs expertise and knowledge. New data, phenomenon, and syndromes are continually discovered by the ECG. It is important to differentiate between normal and abnormal ECGs first and then try to correlate the findings with clinical pathologies. Furthermore, the ECG is an integral part of the screening model for a variety of conditions such as channelopathies, athletes, preoperative risk profile, and remains the cardiologist's best friend...

REVIEW
Kay Maeda, Yoshikatsu Saiki
Given that an increasing number of elderly patients are undergoing surgical procedures for a diversity of indications, the concept of frailty is currently being examined in more depth in clinical medicine. Established surgical risk scores designed to predict mortality are mainly focused on general demographic information and clinical factors; however, these do not account for the frailty condition. With vulnerability and low resiliency in the frail elderly, these conventional scores are unable to accurately predict postoperative outcomes including adverse complications, disability, the need for additional rehabilitation, and prolonged length of hospitalization...

The past two decades have seen an increasing recognition that the delivery of safe surgery with low complication rates and good long-term outcomes is a team endeavour embracing the whole patient care pathway. The key role of the anaesthetist in managing the patient through the surgical process is widely understood and has driven the emergence of perioperative medicine. In parallel with these developments there has been a sea change in the organisation of the care of patients presenting for elective abdominal aortic aneurysm (AAA) repair...

There is no evidence about evaluating accessory infraorbital foramen by 3-dimensional analysis like multi slice computed tomography or cone beam computed tomography (CBCT) in human subjects. To authors' best knowledge this is a first study to assess the accessory infraorbital foramen and position of infraorbital foramen in relation to crown of maxillary teeth using CBCT. This study primarily aimed to assess the location and number of accessory infraorbital foramen (AIOF), to measure the distance between main infraorbital foramen and AIOF and secondarily to determine the position of infraorbital foramen in relation to crowns of maxillary second premolar, first molar, and second molar...

BACKGROUND: Asian noses are relatively small and flat compared to Caucasians; therefore, rhinoplasty procedures often focus on dorsal augmentation and tip projection rather than reduction in the nasal framework. Various autologous and alloplastic implant materials have been used for dorsal augmentation. Recently, human acellular dermal matrices have been introduced as an implant material for dorsal augmentation, camouflaging autologous implants without an additional donor site. Here, we introduce a cross-linked human acellular dermal matrix as an implant material in augmentation rhinoplasty and share the clinical experiences...

BACKGROUND: In modern rhinoplasty, septal cartilage is the most commonly used graft material. It is a big challenge if septal cartilage is insufficient. We present an alternative technique named the "rabbit flap," created from the cephalic portion of the lower lateral cartilage to show its effectiveness on nasolabial angle, nasal axis deviation, and nasal dorsal line. METHODS: An alternative flap, called a "rabbit flap," is constituted from the cephalic portion of the lower lateral cartilage (LLC)...
