Background: The purpose of this study was to determine whether the aesthetic results of subpectoral augmentation mammaplasty using anatomically shaped versus round prostheses are differentiable.
Methods: Thirty observers (i.e., plastic surgeons and nurses) assessed preoperative and postoperative photographs (frontal and oblique views) of 30 patients who had undergone subpectoral augmentation mammaplasty with cohesive silicone gel implants, with an average implant volume of 295 cc (range, 220 to 340 cc). The observers classified each case as round or shaped on two different occasions with a 12-week time interval. A statistical concordance analysis was performed, calculating the overall concordance rate, the interobserver, the intraobserver, and the overall intraobserver kappa indexes, to evaluate the expert observers' capacity to differentiate the implant type.
Results: Among the total of 1800 observations (30 observers assessed 30 cases on two occasions), the overall concordance rate was 50.33 percent (95 percent CI, 47.99 to 52.67). The interobserver kappa value was 0.010 (95 percent CI, 0.0025 to 0.04). The overall intraobserver kappa value was 0.0602 (95 percent CI, 0.0025 to 0.123). The observers were unable to recognize the type of implant used, nor was interobserver concordance noted. An agreement was not reached before the different observers, nor was an intraobserver concordance seen between the first and second classifications of the same cases by each observer.
Conclusion: The results obtained from subpectoral augmentation mammaplasty using anatomically shaped and round prostheses with a volume of 340 cc or less are indistinguishable, not justifying the systematic use of anatomically shaped implants in this patient.

The qualitative analysis of trabecular architecture of the proximal femur based on the P45 sectional plastination technique.

The primary weight-bearing structure of the proximal femur, trabecular bone, has a complex three-dimensional architecture that was previously difficult to comprehensively display. This study examined the spatial architecture of trabecular struts in the coronal, sagittal, and horizontal sections of the proximal femur using 21 cases prepared with P45 sectional plasticization. The primary compressive strut (PCS) exhibited a "mushroom-like" shape with upper and lower parts.

Background: To achieve successful anatomic rotator cuff repair with minimal tension, both the tear pattern and tear size should be considered. However, little information is available concerning the frequency of tear patterns and their effects on tendon healing.
Purpose: To evaluate the distribution of tear patterns in full-thickness rotator cuff tears and whether these patterns affect tendon healing after arthroscopic repair.
DenseSeg: joint learning for semantic segmentation and landmark detection using dense image-to-shape representation.

Purpose: Semantic segmentation and landmark detection are fundamental tasks of medical image processing, facilitating further analysis of anatomical objects. Although deep learning-based pixel-wise classification has set a new-state-of-the-art for segmentation, it falls short in landmark detection, a strength of shape-based approaches.
Methods: In this work, we propose a dense image-to-shape representation that enables the joint learning of landmarks and semantic segmentation by employing a fully convolutional architecture.
[Analysis of influencing factors on the height of gingival papilla around implants].

The anatomical structure of the gingival papilla around the implant is special, and it is difficult to recover after injury. The reduction of its height will have a negative impact on function and esthetics, and it is one of the many problems in implant treatment at present. This paper analyzes the influencing factors of implant gingival papilla height from three aspects: anatomical factors, implant surgical design and implant restorative design, including the classical influencing factors such as the shape of natural teeth, interproximal distance between the implant and the adjacent tooth, soft tissue grafting, and contour of implant restorations, as well as the hot and controversial influencing factors in recent years such as the thickness of soft tissues around the implant, the implant surgical timing, the flap design, and the surgical incision, in order to provide reference for clinicians in the process of implant treatment for gingival papilla preservation and reconstruction.

The sphenoidal sinus septum is one of the most important landmarks during endonasal endoscopic transsphe-noidal operations. During routine coronal sectioning of the face, we found a variant Y-shaped septum in the sphenoidal sinus of a female cadaver. This unusual septum was found between two sections (anterior and posterior sections) and located inferior to the pituitary gland.
