One of the most challenging and least predictable procedures in periodontal plastic surgery is the reconstruction of the lost interdental papilla. Preserving the integrity of the papillae is of utmost importance. Different variations of surgical procedures using connective tissue grafts have proved to be successful. Being less invasive in nature, non-surgical techniques such as hyaluronic acid injections have turned out to be a boon in this regard. Platelet concentrates like PRF & PRP have shown promising results when used in surgical reconstruction of the lost papilla. One of the recent advancements in PRF formulations is the injectable PRF which is a liquid concentrate encompassing higher leuckocyte numbers, which resulted in higher total growth factor release, requiring slower and shorter centrifugation speeds for preparation. i-PRF was shown to be a potent inducer of cell proliferation, migration and angiogenesis, inducer of higher broblast migration and expression of PDGF, TGF-β, and collagen,thereby playing a vital role in tissue regeneration. With the current understanding, this study was designed to investigate the efciency of iPRF in achieving interdental papillary enhancement. We have noted that mutilple doses of this autologous formulation prove to be a non-invasive alternative for the treatment of minimal interdental papilla loss; primarily Norland & Tarnow's Class I and to an extent Class II interdental papilla loss. Further validations of this technique are required

ABSTRACT Increasing esthetic demands of the modern era has converted modern dentistry to pink and white esthetic dentistry. One of the most difficult goals in the regeneration of the soft tissues is the reconstruction of interdental papilla. A number of techniques have been tried, but the results still lack predictability. Nonsurgical techniques include repeated curettage of the interdental papilla, orthodontic and restorative correction, and hyaluronic acid application, while surgical techniques include pedicle and free gingival graft, connective tissue grafts, and subepithelial connective tissue graft. This article presents a report of two cases where a combination of platelet-rich fibrin (PRF) and pedicle graft was utilized to retain maximum vascularity and minimize scar tissue formation. The atraumatic management of the tissues with a pouch-like design avoids tension and pressure and is critical for the success of the procedure. Adequate fill of the interdental papilla was observed in both the cases and the results were stable up to 6 months. How to cite this article Sharanappa M, Konuganti K, Kumar A, Rima.

Abstract Anterior Cruciate Ligament (ACL) tear is one of the most common knee injuries. The ACL reconstruction surgery aims to restore healthy knee function by replacing the injured ligament with a graft. Proper selection of the optimal surgery parameters is a complex task. To this end, we developed an automated modeling framework that accepts subject-specific geometries and produces finite element knee models incorporating different surgical techniques. Initially, we developed a reference model of the intact knee, validated with data provided by the OpenKnee project. This helped us evaluate the effectiveness of estimating ligament stiffness directly from MRI. Next, we performed a plethora of “what-if” simulations, comparing responses with the reference model. We found that a) increasing graft pretension and radius reduces relative knee displacement, b) the correlation of graft radius and tension should not be neglected, c) graft fixation angle of 20 degrees can reduce knee laxity, and d) single-versus double-bundle techniques demonstrate comparable performance in restraining knee translation. In most cases, these findings confirm reported values from comparative clinical studies. The numerical models are made publicly available, allowing for experimental reuse and lowering the barriers for meta-studies. The modeling approach proposed here can complement orthopedic surgeons in their decision-making.

Postprostatectomy vesicourethral anastomotic stenosis (VUAS) remains a challenging problem for both patient and urologist. Improved surgical techniques and perioperative identification and treatment of risk factors has led to a decline over the last several decades. High-level evidence to guide management is lacking, primarily relying on small retrospective studies and expert opinion. Endourologic therapies, including dilation and transurethral incision or resection with or without adjunct injection of scar modulators is considered first-line management. Recalcitrant VUAS requires surgical reconstruction of the vesicourethral anastomosis, and in poor surgical candidates, a chronic indwelling catheter or urinary diversion may be the only option. This review provides an update in the diagnosis and management of postprostatectomy VUAS.

Abstract Background: We aimed to compare the results of two surgical methods for the treatment of congenital supravalvular aortic stenosis. Methods: From May 2004 to January 2020, 29 patients underwent surgical repair for supravalvular aportic stenosis in a single centre. The perioperative evaluation of the patients was retrospectively reviewed. Results: Fifteen (51.7%) and 14 (48.2%) patients were treated with the Doty and the McGoon methods, respectively. The median age of our cohort was 4.5 (3.0–9.9) years. Ten (34.5%) patients had Williams–Beuren syndrome, and pulmonary stenosis was observed in 12 (41.3%) patients. The median follow-up time was 2.5 (0.7–7.3) years. On follow-up, five patients had residual stenosis with the McGoon technique and one with the Doty technique (p = 0.05). One patient died early in the post-operative period in the Doty group, and three patients were re-operated on due to restenosis in the McGoon group. Freedom from re-operation in the Doty group at 1, 3, 5, and 10 years was 100%. In the McGoon group, freedom from re-operation rates at the 1-, 3-, and 7-year follow-up were 100, 88.9, and 44.4%, respectively (p = 0.08). Conclusion: Our results with both surgical techniques suggest that supravalvular aortic stenosis can be treated with good results. The Doty method provided better relief for the supravalvular aortic segment, considering the residual stenosis and the re-operation rates.

Abstract Purpose of Review To provide the reader with a clear overview of facial anatomy as it relates to injection of botulinum toxin. Recent Findings The review suggests the presentation of multiple combinations of facial musculature, with the forehead, glabellar, and nasal base areas as particular areas of variation. Differences in musculature result in different wrinkling patterns; with age, these changes first become apparent in the upper face, particularly in the forehead and glabellar area. Summary Botulinum toxin is well suited to achieve the optimal outcome: it is popular, safe, and non-invasive and presents with few adverse effects. Though limited, when adverse effects do arise these are primarily related to poor injection technique, often fuelled by poor anatomical knowledge. For clinicians to achieve the best outcomes with botulinum toxin use, an understanding of the facial muscles’ anatomy, actions, and interactions is key. This paper discusses the broad and intricate detail regarding the key target muscles of botulinum toxin, based on both literature review and cadaveric dissection carried out by the authors.

Category: Ankle, Ankle Arthritis, Diabetes, Hindfoot, Trauma Introduction/Purpose: Deformity associated with Charcot Foot Arthropathy leads to a poor quality of life in affected individuals. Deformity in the midfoot appears to be predictive of clinical outcomes following surgical correction. The goal of this retrospective study was to determine if that same methodology could be applied to patients treated for Charcot Foot Arthropathy involving the ankle joint. Methods: Fifty-six consecutive patients underwent surgical reconstruction of Charcot Foot deformity involving the ankle joint by a single surgeon over a fourteen year period. Preoperative patient characteristics and tibiotalar alignment, were recorded. Surgical treatment included single stage debridement of active infection and ankle arthrodesis with application of a circular external fixator when infection was present (39 of 56, 69.6%) or retrograde locked intramedullary nailing in the absence of infection (17 of 56, 30.3%). Clinical outcomes were graded based on limb salvage, resolution of infection and chronic wounds, and the ability to ambulate with therapeutic footwear or accommodative orthoses. The average follow-up was 7.5 (range 1.1-14.0) years. Results: One patient died at 134.3 weeks following surgery of unrelated causes and 8 underwent amputation. Twenty eight of 56 patients (50.0%) achieved a favorable (excellent or good) clinical outcome. There was no significant association between preoperative or postoperative alignment and clinical outcomes. Insulin-dependent diabetics were approximately 3 times more likely to have a poor clinical outcome. Conclusion: Surgical correction of Charcot deformity involving the ankle joint was associated with a high complication rate and risk for failure. The lessons learned from this highly co-morbid patient population with complex deformities can be used as a benchmark for applying modern surgical techniques.
