entire papilla Preservation Technique a novel surgical approach for regenerative treatment of deep and wide intrabony defects
International Journal of Periodontics & Restorative Dentistry, 2017Co-Authors: Serhat Aslan, Nurcan Buduneli, Pierpaolo CortelliniAbstract:Primary wound closure and uneventful early wound stability over the biomaterials are the most critical elements of successful periodontal regeneration. Yet the surgical elevation of the interdental papilla to access deep and wide intrabony defects entails an impairment of the papillary blood supply that can result in difficult healing due to a lack of primary closure in the early healing period. This negative event might complicate the healing process, favoring bacterial contamination. A novel modified tunnel surgical Technique designed to maintain the integrity of the interdental papilla is presented in this article, with the aim of providing an optimal environment for wound healing in regenerative procedures. Entire papilla Preservation is described and applied in three different cases, in association with the use of a combination of bone substitutes and enamel matrix derivative for periodontal regeneration. The entire papilla Preservation Technique was successfully applied to the three selected cases, resulting in an uneventful postsurgical period and a substantial defect fill over the 8-month follow-up. This tunnel-like Technique can be recommended for further research to support the success identified in this case series.

the modified papilla Preservation Technique a new surgical approach for interproximal regenerative procedures
Journal of Periodontology, 1995Co-Authors: Pierpaolo Cortellini, Giovanpaolo Pini Prato, Maurizio S TonettiAbstract:A modification of the papilla Preservation Technique has been applied to achieve primary closure of the interproximal tissue over barrier membranes placed coronal to the alveolar crest. Fifteen patients with deep intrabony interproximal defects were treated. Defects had a probing attachment level loss of 9.9 +/- 3.2 mm and a recession of the gingival margin of 1.7 +/- 1.6 mm. The depth of the intrabony component was 5.5 +/- 2.9 mm; while the suprabony component was 5.9 +/- 2.0 mm. Titanium-reinforced teflon membranes were placed 1.3 +/- 0.7 mm from the cemento-enamel junction, 4.5 +/- 1.6 mm coronal to the interproximal alveolar bone crest. Primary closure over the interproximal portion of the membrane was obtained in 93% of cases. In 73% of the cases complete coverage of the membrane was maintained until its removal at 6 weeks. These data indicate that the modified papilla Preservation Technique can be successfully applied to obtain primary closure of the interdental space in regenerative procedures with barrier membranes.

magnetic resonance imaging evaluation of anterior cruciate ligament reconstruction using quadrupled hamstring tendon autografts comparison of remnant bundle Preservation and standard Technique
American Journal of Sports Medicine, 2010Co-Authors: Jin Hwan Ahn, Sang Hak Lee, Sang Hee Choi, Tae Kang LimAbstract:Background: Recently, variations of the remnant bundle Preservation Technique, including selective bundle reconstruction and Preservation of the anterior cruciate ligament tibial remnant, have produced good outcomes. The authors chose to investigate whether remnant bundle Preservation in anterior cruciate ligament reconstruction would affect the remodeling process without inducing complications.Hypothesis: An anterior cruciate ligament reconstruction graft can be augmented with a tensioned remnant of the native anterior cruciate ligament fibers without increasing the tendency of cyclops lesions. The magnetic resonance imaging signal intensity in an anterior cruciate ligament graft using the remnant bundle Preservation Technique would be lower than that using the standard Technique.Study Design: Cohort study; Level of evidence, 3.Methods: Forty-one patients who underwent an anterior cruciate ligament reconstruction using the remnant bundle Preservation Technique with quadrupled hamstring tendon autograft w...

total rib Preservation Technique of internal mammary vessel exposure for free flap breast reconstruction a 5 year prospective cohort study and instructional video
Annals of medicine and surgery, 2015Co-Authors: Anais Rosichmedina, Charles M Malata, Michele Di Candia, Serafeim BouloumpasisAbstract:Introduction The total ‘rib’-Preservation method of dissecting out the internal mammary vessels (IMV) during microvascular breast reconstruction aims to reduce free flap morbidity at the recipient site. We review our five-year experience with this Technique.

tips for successful microvascular abdominal flap breast reconstruction utilizing the total rib Preservation Technique for internal mammary vessel exposure
Annals of Plastic Surgery, 2011Co-Authors: Charles M Malata, Michael Moses, Zita Mickute, Michele Di CandiaAbstract:Introduction: The internal mammary vessels (IMVs) are increasingly the recipients for free flap breast reconstruction (FFBR). Access traditionally entails removing a segment of the third costal cartilage. Despite excellent exposure, some authors have reported localized tenderness as well as a thoracic contour deformity. We introduced the “total rib Preservation” Technique for IMV exposure after specific request by a patient, and have used it for all subsequent reconstructions. Methods: All patients who underwent FFBR with rib Preservation by a single surgeon in the year beginning June 2008 were studied prospectively. Intraoperative measurements of the inter-rib space available for microvascular anastomosis were taken. Operative details and flap outcomes were compared with a cohort of earlier patients who underwent rib sacrifice. Results: Over a 12-month period, 42 FFBRs in 37 patients (36 deep inferior epigastric perforator, five muscle-sparing transverse rectus abdominis myocutaneous, and one superficial inferior epigastric artery flap) were performed by a single operator. All flap transfers were successful. In the first 4 patients, the interspace between the third and fourth ribs was used; but for all subsequent patients the second and third rib interspace was used. The average distance between adjacent ribs was 21.3 mm (range, 9–28 mm) and the vessel preparation time decreased from an average of 93 to 49 minutes (first and last 5 cases). There was no significant difference in mean ischemia time between the rib Preservation and the rib sacrifice groups (104.4 vs. 103.6 minutes). Conclusions: The total rib Preservation method of IMV exposure is a viable, reproducible, and reliable option for microvascular breast reconstruction. It does not increase warm ischemia, which suggests time taken for anastomosis is not affected by rib Preservation. There is a learning curve and care has to be taken to avoid possible pitfalls. We recommend the use of a higher rib interspace than originally described because of the greater vessel calibre, superior vessel exposure, and therefore, easier anastomosis.

all inside anterior cruciate ligament reconstruction with augmentation using the native anterior cruciate ligament remnant by suture approximation
Arthroscopy techniques, 2021Co-Authors: George El Rassi, Joseph Maalouly, Antonios Tawk, Dany AouadAbstract:Abstract Anterior cruciate ligament (ACL) rupture remains a debilitating orthopaedic pathology with a substantial economic and psychological burden on patients, especially athletes. The purpose of ACL reconstruction is to attain maximum joint stability and functionality, allowing patients to resume their previous level of activity. Several graft options and Techniques are available for ACL reconstruction. The all-inside remnant-Preservation Technique is a minimally invasive approach aiming for improved proprioception, better graft integration, and increased graft strength via ACL augmentation by suture approximation with an optimal anatomic reconstruction. ACL augmentation is associated with a decreased risk of rerupture. Moreover, enhancement of knee proprioception via the presented Technique allows an early return to activity by patients because weight bearing (with a brace) can be initiated as early as day 1 postoperatively. Patients can resume running activities by 2 months postoperatively and return to pivot sports by 3 months postoperatively. Despite this surgical procedure being technically demanding, it is associated with improved clinical outcomes and functional capacities. Patients are also found to better tolerate the postoperative rehabilitation protocol.
