Effectiveness of Resective Surgery in Complex Ameloblastoma of the Jaws: A Retrospective Multicenter Observational Study.

Ameloblastoma is a rare, benign, odontogenic tumor of epithelial origin, characterized by locally aggressive, expansive growth. Treatment is controversial due to the risk of relapse. The aim of this multicenter retrospective study was to evaluate the effectiveness of complete resection in cases of complex ameloblastoma, which is considered at a higher risk of recurrence. Patients who met at least one of these criteria were included: recurrence, soft-tissue involvement, complete erosion of internal/external cortical walls with involvement of the inferior margin of the mandible, and invasion of the maxillary sinus or nasal cavity. Demographic data, tumor site, type of surgery, histological features, and follow-up information were collected for each patient. The cohort included 55 patients with a mean follow-up of 108 ± 66 months. A multivariate logistic model was used to evaluate variables independently associated with relapse. There were six soft-tissue or maxillary sinus relapses, with a recurrence rate of 10.9%. Most of them arose in patients previously treated. The statistical analysis identified the maxillary location as a fundamental relapse risk factor. En bloc resection with large surgical safety margins seemed to be effective in preventing the relapses. However, complete resection was less effective in preventing recurrences in the soft tissues or maxillary sinus.

Surgical Treatment and Rehabilitation Strategies for Upper and Lower Extremity Lymphedema: A Comprehensive Review.

Lymphedema is a chronic disabling condition affecting a growing number of patients worldwide. Although lymphedema is not life-threatening, several reports underlined detrimental consequences in terms of distress, pain, functional impairment, and infections with a relevant decrease in quality of life. Currently, there is no cure, and the therapeutic management of this condition aims at slowing down the disease progression and preventing secondary complications. Early diagnosis is paramount to enhance the effects of rehabilitation or surgical treatments. On the other hand, a multidisciplinary treatment should be truly integrated, the combination of microsurgical and reductive procedures should be considered a valid strategy to manage extremity lymphedema, and rehabilitation should be considered the cornerstone of the multidisciplinary treatment not only for patients not suitable for surgical interventions but also before and after surgical procedures. Therefore, a specialized management of Plastic Reconstructive Surgeons and Physical and Rehabilitative Medicine physicians should be mandatory to address patients' needs and optimize the treatment of this disabling and detrimental condition. Therefore, the aim of this review was to characterize the comprehensive management of lymphedema, providing a broad overview of the potential therapy available in the current literature to optimize the comprehensive management of lymphedema and minimize complications.

Soft palate reconstruction with free jejunum flap: Impact on the velopharyngeal insufficiency.

If inadequately reconstructed, large resections of the soft palate inevitably cause velopharyngeal insufficiency, nasal regurgitation and reduce speech intelligibility. A series of 12 free Jejunal flaps are presented, with 28.5 months median follow up (IQR 10.5), with evidence that the flaps provided appropriate secretions and good functionality for speech and resumption of oral intake. A retrospective case series was performed, from 2004 to 2020, including patients diagnosed with palate locally advanced squamous cell carcinoma and reconstructed with free jejunum flap. Twelve patients were included, with mean age of 66 years. No flap loss, thrombosis or infection were recorded. Oral feeding was achieved in all patients, on an average after 36 days from the operation. Speech intelligibility improved by 4 points in a scale 0-10. The thin, pliable, and elastic properties of the free jejunal flap are optimally suited for a functional reconstruction of the three-dimensional palatal defects. With its serous and mucous secretion, the free jejunal flap can lead to early return to solid diet and minimize functional impairment of phonation and speech.

Reducing complications in reconstruction of the cervical esophagus with anterolateral thigh flap: The five points protocol.

Patients suffering from hypopharyngeal cancer commonly present in the advanced stage and undergo a circumferential pharyngolaryngectomy. The possibility to reconstruct the esophagus and achieve an oral alimentation can significantly reduce the additional burden of a jejunostomy. The cervical esophagus is usually reconstructed with jejunal free flap (JFF) or fasciocutaneous free flap such as the anterolateral thigh (ALT) free flap. The latter has proved its donor-site safety and fast recovery. However, it is burdened by a high fistula rate. We present our five points protocol for reducing fistula rate and improving outcome. Twenty-eight patients underwent total pharyngolaryngectomy and required esophageal reconstruction with ALT flap from 2015 to 2020. In each patient, we performed five adjustments: a thicker dermal layer, a two-layer closure, a barrier from the tracheostomy, a nonabsorbable monofilament suture, and two NG tubes to enhance neoesophageal drainage. Twenty-five (89%) patients returned to solid or soft food diet after the reconstruction. Three patients had liquid diet. Contrast media leakage was observed in only 2 (7%) patients during esophagography at three weeks, with only one needing surgical revision. Our five points protocol for ALT reconstruction of cervical esophagus proved to be effective in achieving an incredibly low rate of complications, without the burden of significant donor-site complications.

Perforator-based Adipofascial Flaps and ADM: A Novel Combined Approach to Distal Lower Extremity Defects.

Due to the wide spectrum of lower extremity defect presentation, various reconstructive techniques are available. Classic adipofascial flaps are still a second choice. The authors described a new multistage reconstructive approach with perforator-based pedicled adipofascial flap. METHODS: This retrospective study analyzed data of 23 patients undergoing adipofascial flap reconstruction after distal leg trauma between June 2017 and January 2020. A reconstructive approach with an adipofascial flap followed by a skin graft was used in all patients. Patients were divided into two treatment groups, and in only one treatment group, an acellular dermal matrix was placed above the adipofascial flap during the first stage of the reconstruction. Negative pressure wound therapy was applied to both groups. Surgical technique, outcomes, and complications were discussed. RESULTS: All patients achieved complete healing, and no flap loss was reported. Minor complications occurred in four patients; all were treated conservatively on outpatient basis. The surgical and aesthetic results were evaluated as satisfactory from both patients and professionals. However, the group treated with acellular dermal matrix showed a lower complication rate, and resulted significantly more satisfied with the overall results and in several domains of the questionnaire administered postoperatively (P < 0.05). CONCLUSIONS: The adipofascial flap is a safe and effective approach for the reconstruction of small-to-medium-sized defects of the distal lower extremity. Our two-stage reconstructive approach maximizes the pearls offered by the established technique; the dermal matrix guarantees a layered reconstruction optimizing the surgical and aesthetic outcomes of the skin graft with minimal donor site morbidity.

Restoring blood flow to the lateral plantar artery after elevation of an instep flap or medialis pedis flap.

The instep flap and medialis pedis flap are both originate based on the medial plantar artery. The medialis pedis flap is based from the deep branch and the instep flap is based from the superficial branch. To increase the axial rotation, it is acceptable to ligate the lateral plantar artery. However, this can partially affect the blood supply of the plantar metatarsal arch. We restored the blood flow with a vein graft between the posterior tibial artery and the ligated stump. From 2012 to 2020, 12 cases of heel reconstruction, including seven instep flaps and five medialis pedis flaps, were performed with ligation of the lateral plantar artery. The stump of the lateral plantar artery was restored with a vein graft and between the posterior tibial artery and the ligated stump. Patients were followed for 18 months. Long-term results showed the vascular restoration of the lateral plantar artery remained patent demonstrated by doppler ultrasonography. Restoring blood flow to the lateral plantar artery maintains good blood supply to the toes. If the patient in the future develops a chronic degenerative disease, with microvascular complications, bypass surgery can still be performed because of the patency of both branches.

The triple conjoined scapular-latissimus dorsi-groin flap for reconstruction of long lower extremity degloving injury: A case report.

Since the introduction of the angiosome concept, many attempts have been made to push the dimensional limits of free tissue transfers. While initially limited by the boundaries of random vascularization of adjacent angiosomes, wider flaps were transferred by combining contiguous source vessels. Combined flaps, either chimeric or conjoined, represent nowadays the largest reconstructive options in the human body. This is the first report of a triple conjoined free flap with two vascular anastomoses, able to cover the anterior surface of the entire lower limb, representing the longest flap ever reported in history. A 43-year-old woman sustained a car accident as a pedestrian and presented with a massive circumferential degloving injury of the right lower limb. Femoral displaced shaft fracture and Gustilo type IIIb tibial fracture were diagnosed with emergent CT scan. A myocutaneous latissimus dorsi flap was planned, conjoined with the scapular flap to obtain a thick and large cover for the knee, and with a groin flap, to cover for the foot. Descending branch of lateral circumflex femoral artery and anterior tibial artery at the dorsum of the foot were selected as recipient vessels. Donor site was closed primarily. All flaps survived and no immediate nor late complications were reported. Follow up was 3 months. The triple conjoined flap can be considered a safe and useful reconstructive tool in severe degloving injuries of the lower limb, allowing the coverage of a large surface of the lesion with a single operation and without increasing the donor site morbidity.

Genital Lymphedema and How to Deal with It: Pearls and Pitfalls from over 38 Years of Experience with Unusual Lymphatic System Impairment.

Background and Objectives: Conservative treatment represents an essential pillar of lymphedema management, along with debulking and physiologic surgeries. Despite the consistent number of treatment options, there is currently no agreement on their indications and possible combinations. When dealing with unusual lymphedema presentation as in the genitalia (Genital Lymphedema-GL), treatment choice becomes even more difficult. The authors aimed to present their targeted algorithm of single and combined treatment modalities for rare GL in order to face this paucity of information. Materials and Methods: Data were collected from a prospectively maintained database since January 1983, and cases of GL that were managed in the authors' department were selected. Only patients that were treated in the authors' institution and presented a minimum follow-up of 3 months were admitted to the current study. Results: From January 1983 to July 2021, 19 patients with GL were recruited. All the patients were male, and their ages ranged from 21 to 73 years old (average: 52). Ten cases (52.6%) presented with ISL (International Society of Lymphology) stage I, five (26.3%) were stage II and four (21.1%) were stage III. GL was managed with conservative treatment (12 cases), LVA (LymphaticoVenous Anastomosis) (3) or surgical excision (4). In a mean follow-up of 7.5 years (range: 3 months-11 years), no major complications occurred, and all cases reached improvements in functional and quality of life terms. Conclusions: Contrary to the predominant thought of the necessity to avoid surgery in unusual lymphedema presentations such as GL, they can be managed using targeted multimodal approaches or by adapting well-known procedures in unusual ways to achieve control of disease progression and improve patients' quality of life.

Reconstruction of the Nose: Management of Nasal Cutaneous Defects According to Aesthetic Subunit and Defect Size. A Review.

The nose represents the most common site for the presentation of cutaneous cancer, especially in sun-exposed areas: ala, dorsum, and tip. Even the smallest loss of substance can create aesthetic and psychosocial concerns for patients; therefore, surgeons who perform nasal reconstruction should be strictly confident with the pertinent surgical anatomy in order to tailor the procedure to the patient's condition and needs. Radical tumor excision and satisfactory aesthetic and functional results are primary targets. Restoring the original shape is the goal of any reconstruction: appropriate reshaping of three-dimensional geometry, proper establishment of symmetry, and excellent color and texture match to the adjacent structures are paramount features. Multiple options exist to re-establish functional and aesthetic integrity after surgical oncology; nevertheless, the management of nasal defects can be often challenging, and the gold standard is yet to be found. The current goal is to highlight some of the more common techniques used to reconstruct cutaneous defects of the nose with a specific focus on decision making based on the aesthetic subunit and defect size. The authors attempt to share common pitfalls and offer practical suggestions that they have found helpful in their clinical experience.

The integration of orthodontic miniscrews under mechanical loading: a pre-clinical study in rabbit.

INTRODUCTION: Orthodontic miniscrews are an increasingly popular choice to achieve absolute anchorage. The temporary use of miniscrews and their recent introduction have limited the debate over the biological aspect of the materials to that of the surface that permeates the field of dental implants. The aim of the present study was to investigate the integration of grade 5 titanium mini-implants with machined or sand blasted acid etched surface (SAE) under mechanical load in a rabbit tibia model of implant integration. METHODS: A total of 64 miniscrews (Ti6Al4V) of 1.5 mm diameter and 6.5 mm length were inserted in the proximal medial surface of each tibia in eight male rabbits aged 6 months. Each tibia received four miniscrews. A 100 g nickel-titanium coil spring (Neosentalloy) was applied between two miniscrews along the main axis while two miniscrews were left unloaded. The removal torque was measured for loaded and unloaded miniscrews after 12 weeks. Two miniscrews were harvested for histology. RESULTS: Removal torque was significantly higher for SAE mini-implants than for machined screws, under both loading conditions. Although no difference in bone to implant contact was observed among the groups, cortical area significantly decreased with both surfaces under loading. CONCLUSIONS: Our data indicate that SAE miniscrews have higher bone retention than MA miniscrews, although the effects of mechanical loading of these devices on cortical bone require further investigations.
