Anatomic (positional) variation of maxillary wisdom teeth with special regard to the maxillary sinus.

Anatomic (positional) variation of maxillary wisdom teeth with special regard to the maxillary sinus. Swiss Dent J. 2015;125(5):555-71 Authors: Lanzer M, Pejicic R, Kruse AL, Schneider T, Grätz KW, Lübbers HT Abstract The removal of wisdom teeth is one of the most common interventions in oral surgery. In order to avoid complications, a profound knowledge of the anatomy of teeth and adjacent tissues is crucial. In the case of maxillary wisdom teeth, their relationship to the maxillary sinus, to the pterygoid fossa, to the maxillary tuber and the adjacent venous plexus is particularly important. Three-dimensional (3D) imaging, for example by means of cone beam computed tomography (CBCT), is increasingly utilized in practice. However, the necessity of CBCT imaging is still a matter of intensive debate. The aim of this study was to describe the anatomic (positional) variation of maxillary wisdom teeth and, based on these findings, to elucidate the additional benefit of such imaging. A retrospective case study was performed using patients examined by means of CBCT imaging in the Department of Dento-Maxillofacial Radiology during the period from 2008 to 2013. Primary study variables comprised the spatial relationship of the teeth to the maxillary sinus, the degree of retention and root development, the covering of the root with bone and mucosa, the root configuration, and the developmental stage of the tooth. In addition, the association of the inclin...

AbstractDistal humeral fractures represent approximately 2% of fractures in adults and are often treated operatively to restore stable humeral columns and allow early elbow motion. Diagnosis is made with orthogonal radiographs. The traction view radiograph and computed tomography with three-dimensional reconstruction can be helpful in preoperative planning. Treatment options include: (1) nonoperative management, which is reserved for lower-demand, medically unwell, elderly patients, (2) surgical osteosynthesis, which remains the treatment of choice for most fractures, and (3) prosthetic replacement with either hemiarthropl...

AbstractPurposeTo evaluate and characterize anterior chest wall (ACW) joint ’s enthesopathy on CT scans in patients with DISH compared with age- and gender-matched control group.Material and methodsRetrospective evaluation for enthesopathy features of ACW joints —sterno-clavicular (SCJ), manubrio-sternal (MSJ), costo-sternal 1–7 (CSJ)—on chest CT scans of subjects with DISH (Resnick criteria) and of age- and gender-matched control subjects was performed. 183 subjects (DISH: 92, control: 91); male:female: 126:57, average age: 71.7 years (range 50–94 ) were evaluated. Total enthesopathy sco...

ConclusionSternal wire complications secondary to migration beyond the sternum are rare but potentially fatal. Precise wire location and risk assessment with CT are more appropriate when wire location cannot be clearly delineated by plain film radiography.

n E Abstract The role of the patella is paramount in the transmission of the quadriceps muscle forces, the increase of the lever arm, the distribution of the forces on the trochlea and the centring of the extensor apparatus. Despite the low incidence of patellar factures in comparison with other lower limb fractures, the painful and functional complications, such as knee stiffness, loss of extension and patellofemoral osteoarthritis, can be very disabling and will often compromise the return to a professional or recreational activity and induce falls in the elderly population. Treatment can be conservative or surg...

The aim of the study was to determine any discrepancies among preoperative full-leg standing radiographs (LLR) and supine non-weight-bearing computed tomography (CT)-scan-based three-dimensional (3D) models in the assessment of the lower limb alignment prior to total knee arthroplasty (TKA) and answer the question of whether the LLR study can be obviated in preoperative planning when TKA is performed with patient-specific instrumentation (PSI).

ConclusionsAlthough nano-CT has many disadvantages, it enabled the 3D anatomical study of the FMMs in relation to the NLF when combined with iodine staining. We imported the 2D images obtained by nano-CT scanning into the Mimics software, successfully reconstructed the FMMs, and finally obtained images of complex 3D structures of the FMMs. The shapes, positions, and 3D spatial relationships of the FMMs were clearly visualized. The novel insights into the 3D anatomy of the FMMs may help understand the formation of the NLF. Finally, the results of this study may help improve the rejuvenation surgery of the NLF soon.Level of ...

Abstract Artificial intelligence (AI) is a general term that implies the use of a computer to model intelligent behavior with minimal human intervention. AI, particularly deep learning, has recently made substantial strides in perception tasks allowing machines to better represent and interpret complex data. Deep learning is a subset of AI represented by the combination of artificial neuron layers. In the last years, deep learning has gained great momentum. In the field of orthopaedics and traumatology, some studies have been done using deep learning to detect fractures in radiographs. Deep learning studies to det...

Chest radiography and computed tomography revealed that the patency capsule was located within the bronchus intermedius. It was successfully removed by flexible bronchoscopy. The balloon was placed over the capsule and inflated. Subsequently, the catheter was pulled, while thus dragging the capsule with it and...
