RESUMEN

BACKGROUND: In the surgical treatment of head and neck locally advanced malignancies, microvascular free flaps represent the most valuable solution to reconstruct the tissue defect after resection of the primary neoplasm. In particular, microvascular free flaps allow to restore the functional and aesthetical features of the head and neck compartments. The superficial circumflex iliac perforator (SCIP) flap represents, as an evolution of the groin flap, a valid alternative to the radial fasciocutaneous free (RFFF) flap or the anterolateral thigh (ALT) flap. METHODS: This systematic review adhered to the recommendations of the Preferred Reporting Items of Systematic Reviews and Meta-analysis (PRISMA) 2009 guidelines. A computerized MEDLINE search was performed using the PubMed service of the U.S. National Library of Medicine ( www.pubmed.org ) and Scopus database ( www.scopus.com ). Two authors screened the articles, then selected and extracted data on malignancies characteristics, reconstructive techniques, outcomes, and complications. RESULTS: A total of 25 articles were selected and reviewed among the 39 identified through the search string. Six out of the selected 25 articles were case reports, while the remaining 19 articles were retrospective case series. The whole study population was represented by 174 oncologic patients undergoing ablation of a head and neck tumor and reconstruction with a SCIP flap. The site of reconstruction was the oral cavity in 125 (71.0%) patients, being the tongue the most common subsite in 73 (41.5%) patients, the pharynx in 10 (5.7%) cases, the larynx in 3 (1.7%) and head and neck skin in 36 (20.4%) patients. Only two cases of total flap loss were reported. Partial flap loss or shrinkage requiring minor surgical revisions was observed in 11 patients (6.32%). Primary closure of the donor site was achieved in the whole study population, according to the available data. CONCLUSIONS: In head and neck postoncological reconstruction, despite the caliber and the length of the pedicle, SCIP flap offers a pliable and thin skin paddle, allowing single-stage resurfacing, medium to large skin paddle, possibility of composite-fashion harvest and a well-concealed donor site.

RESUMEN

Sternal wound complications following cardiac surgery, including sternal dehiscence, mediastinitis, and osteomyelitis, pose significant challenges in terms of management and patient outcomes. We present a case report highlighting the complex management of a patient who underwent open heart surgery for severe aortic valve stenosis, followed by sternal wound dehiscence and sternum osteomyelitis due to extended spectrum beta lactamase (ESBL) producing Klebsiella aerogenes. A multiple myeloma diagnosis was also suspected at the positron emission tomography (PET) scan and confirmed with bone marrow biopsy. Multidisciplinary evaluation of the case led to a comprehensive treatment plan. To control the sternal osteomyelitis, total sternectomy was performed followed by immediate reconstruction with a bone (tibia) graft from the tissue bank and fixation with the minimal hardware possible. A microsurgical latissimus dorsi free flap was required to reconstruct the soft tissue defect. After 6 weeks of antibiotic treatment with ertapenem and fosfomycin based on a culture of intraoperative material, no clinical, imaging, or laboratory signs of infection were seen. Multiple myeloma treatment was then started. At 1 year of follow up, no recurrence of infection occurred, and the reconstruction was stable and closed. Multiple myeloma is under chronic treatment with novel agent combination, with an excellent haematological response.

RESUMEN

The pelvic anatomy poses great challenges to orthopedic surgeons. Sarcomas are often large in size and typically enclosed in the narrow confines of the pelvis with the close proximity of vital structures. The aim of this study is to report a systematic planned multidisciplinary surgical approach to treat pelvic sarcomas. Seventeen patients affected by bone and soft tissue sarcomas of the pelvis, treated using a planned multidisciplinary surgical approach, combining the expertise of orthopedic oncology and other surgeons (colleagues from urology, vascular surgery, abdominal surgery, gynecology and plastic surgery), were included. Seven patients were treated with hindquarter amputation; 10 patients underwent excision of the tumor. Reconstruction of bone defects was conducted in six patients with a custom-made 3D-printed pelvic prosthesis. Thirteen patients experienced at least one complication. Well-organized multidisciplinary collaborations between each subspecialty are the cornerstone for the management of patients affected by pelvic sarcomas, which should be conducted in specialized centers. A multidisciplinary surgical approach is of paramount importance in order to obtain the best successful surgical results and adequate margins for achieving acceptable outcomes.

RESUMEN

OBJECTIVE: To evaluate the features and prognosis of melanoma of glans penis and urethra, with the presentation of a significant case report. MATERIALS AND METHODS: A systematic literature review was performed using the MEDLINE (PubMed) and Cochrane Libraries databases to identify all cases of male mucosal melanoma reported. RESULTS: Two hundred fifty-two patients with male mucosal primary melanoma were found. Glans penis and fossa navicularis as primary site includes the 81.6% of all lesions considered. Median Breslow's depth is 2.1 mm, whereas nine in situ melanomas have been reported. At the diagnosis, the disease was at a non-localized stage in 21.4% for glans penis melanomas and 11.7% urethral lesions, respectively. The 2 and 5-year survival for glans melanoma is 62.5% and 38.4%; higher rates were observed in the 2012-2020 period (76% and 58.8%, respectively). Two-year survival for urethral melanomas is 66.7%, while 5-year survival is 12.5%. 22 patients survived over 5 years with a Breslow's depth reported always < 3.3 mm. CONCLUSION: Melanoma of the glans penis and urethra is a rare neoplasm associated with a poor prognosis, however recent reports show higher survival rates. Surgery remains the mainstay for a localized disease. Taking into account the small number of cases reported, topical imiquimod seems to be a valid non-surgical alterative for melanoma in situ. The use of immunotherapy and targeted therapy should be considered only in an adjuvant setting according to the recommendations of cutaneous melanoma; however, additional clinical data on male mucosal melanoma are needed to draw definitive conclusions.

RESUMEN

This series reports on the treatment of distal tibia (DT) fracture-related infections (FRI) with a combined orthoplastic approach. Thirteen patients were included. In eight patients with extensive bone involvement and in those with a non-healed fracture, the DT was resected ("staged approach"). In five cases, the DT was preserved ("single-stage approach"). A wide debridement was performed, and the cavity was filled with antibiotic-loaded PerOssal beads. All patients had a soft-tissue defect covered by a free vascularized flap (anterolateral thigh perforator flap in eight cases, latissimus dorsi flap in five). At the final follow-up (mean 25 months, range, 13-37), no infection recurrence was observed. In one patient, the persistence of infection was observed, and the patient underwent a repeated debridement. In two cases, a voluminous hematoma was observed. However, none of these complications impacted the final outcome. The successful treatment of FRI depends on proper debridement and obliteration of dead spaces with a flap. Therefore, when dealing with DT FRI, debridement of infected bone and soft tissues must be as radical as required, with no fear of the need for massive reconstructions.

RESUMEN

BACKGROUND: A good inframammary fold (IMF) definition and position is essential to achieve a satisfactory and natural result in breast surgery. This structure can be damaged, especially during mastectomies. Multiple methods are reported in the literature to restore IMF or improve its definition. In this study, we present the results achieved in a series of patients treated with subdermal liposuction. METHODS: We report on all our patients who underwent IMF liposuction between January 2016 and June 2020. Subdermal liposuction was performed with a blunt 3 mm cannula along the new IMF to promote skin retraction and adherence between skin and fascia. Results were evaluated subjectively by the patients and objectively by 8 individuals not involved with the treatment. RESULTS: We performed IMF liposuction in 88 breasts (69 patients), aged 21-74 (mean 52) years for 82 implant-based reconstructions, 2 tuberous breasts, and 4 contralateral breast augmentations. Mean follow-up was 28 months (6-64). Subjective results: the overall result evaluated with the VAS scale reached 86.6/100. All the 22 patients interviewed judged as well defined the new inframammary fold. Objective results: in 83% of cases the definition of the inframammary fold was judged as good or excellent, while symmetry with contralateral IMF, natural appearance, and overall aesthetic outcome were judged as good. CONCLUSION: Based on our long-term satisfactory results, we recommend the technique of subdermal liposuction to improve the definition of IMF in breast reconstruction after mastectomy and other breast procedures. It is effective, easy to perform, minimally invasive, and durable.

RESUMEN

After removal of an infiltrative BCC of the auditory meatus, a soft tissue defect of the temporal-mastoid area with bone exposure, needed reconstruction. Several options have been taken into account and a simple yet effective solution has been found following the spare-parts principle. The ear lobe, preserved during cancer removal, was split and used as a thin skin flap. Adequate coverage of the bone exposure and resurfacing of the external auditory canal was obtained with minimal donor site morbidity and a short surgery in a fragile patient with several comorbidities. The spare-parts strategy can provide successful solution to difficult reconstructive cases regardless of the anatomical area.

RESUMEN

BACKGROUND: Deep inferior epigastric perforator (DIEP) flap reconstruction is the gold standard reconstructive technique for women undergoing breast cancer surgery. A preoperative computed tomography angiography (CTA)-dedicated protocol and 3D reconstructions are mandatory for correct surgical planning. PURPOSE: To evaluate the diagnostic performance of a new preoperative CTA protocol and a new reconstruction method in the assessment of DIEP technique. MATERIAL AND METHODS: A total of 263 women (median age 49 years, age range 26-73 years) underwent preoperative CTA examination before DIEP flap breast reconstruction. A CTA-dedicated protocol followed by 3D-reconstructions were performed. Identification, branching pattern, and caliber at origin were assessed for each perforator. Intraoperative findings were the standard of reference. The sensitivity, positive predictive value, and diagnostic accuracy of the preoperative CTA protocol were calculated. RESULTS: In 255/263 (97%) patients, the dominant perforators assessed by CTA resulted adequate for surgical reconstruction. In 260/263 (99%) cases, the imaging localization of the dominant perforators corresponded with those seen intraoperatively (mean errors ≤1 cm). The preoperative CTA imaging sensitivity, positive predictive value, and diagnostic accuracy in determining the localization of perforators were 99% (95% CI 98-100), 100% and 99% (95% CI 98-100), respectively. No statistically significant differences were found between the CTA findings and the surgical findings for the assessment of branching pattern and caliber of the dominant perforators (P < 0.001). CONCLUSION: The present protocol has demonstrated high accuracy in the CTA imaging assessment of the perforators before DIEP flap reconstruction with high reproducibility between CT and surgical findings.

RESUMEN

BACKGROUND: Venous congestion is the most common perfusion-related complication of deep inferior epigastric artery perforator (DIEP) flap. Several hydraulic constructs can be created for venous superdrainage in case of flap venous engorgement or as a preventive measure. These can be classified based on the choice of the draining vein of the flap, either a second deep inferior epigastric vein (DIEV) or a superficial inferior epigastric vein (SIEV), and of the recipient vein, either a vein of the chest or the DIEV. METHODS: We conducted a comprehensive systematic literature review in Medline, Scopus, EMBASE, Cochrane Library, and Google Scholar to find publications that reported on venous congestion in DIEP flap. The keywords used were DIEP Flap, breast reconstruction, venous congestion, supercharging, superdrainage, SIEV, and DIEV. RESULTS: Based on the studies found in the literature, we developed an algorithm to guide the surgeon's decision when choosing the veins for the superdrainage anastomosis. CONCLUSION: Several alternatives for venous anastomosis in superdrainage are available. We propose an algorithm to simplify the choice. The use of the ipsilateral SIEV to be connected to a vein of the chest appears to be advantageous. The anatomical position that allows the easiest anastomosis dictates which chest vein to favor.

RESUMEN

BACKGROUND: Reconstruction of complex defects involving nose and close facial units represents an aesthetic and functional challenge. Restoring satisfactory nasal shape, combining aesthetic, nasal function and patent airways is mandatory. In this paper, we describe our approach to total nose defects and we report our 20-year experience in microvascular nose reconstruction.Clinical cases are shown to illustrate different surgical techniques and the evolution of our approach. METHODS: Nasal reconstruction procedures were performed on 21 patients between 2000 and 2020 using the radial forearm flap (RFF) or anterolateral thigh (ALT) flap. Reported reconstructions included total/subtotal nasal defects, caused by cancer resections. The key point of our approach is the expanded forehead flap for skin coverage. Reconstruction is completed by cartilage grafts to restore nasal framework and to shape nasal tip. Ancillary procedures were needed in some cases to optimize aesthetic outcomes. RESULTS: Twenty-one patients completed the multistage nasal reconstruction. The RFF flap was used in 56% of the cases (n = 11), while the ALT flap was used in 44% (n = 10) of our case series. No difference has been detected in the number of reconstructive stages required to achieve the final result comparing RFF and ALT reconstruction (3.3 vs. 3.1 reconstructive steps). Ancillary procedures were performed in 7 patients. CONCLUSION: Microvascular tissue transfer plays a key role in full-thickness nasal defects restoration. Comparing the two groups, both the RFF and ALT are effective and reliable options in lining reconstruction, although with different indications. Expanded forehead flap, combined to free cartilage graft, is our gold standard to provide external skin coverage to rebuild the nasal framework. According to our current approach, accurate preoperative planning, supported by modern technologic tools, multistage reconstruction, and ancillary procedures are useful to accomplish satisfactory functional and aesthetic outcomes.

RESUMEN

INTRODUCTION: Venous congestion is the most common vascular complication of the deep inferior epigastric artery perforator (DIEP) flaps. Adding a second venous drainage by anastomosing a flap vein and a recipient vein (super-drainage) is considered the solution of choice. Evidence to support this procedure, had not yet been confirmed by an analysis of the literature. We aimed to provide this evidence. MATERIALS AND METHODS: We searched the literature (MedLine, Scopus, EMBASE, Cochrane Library, and Google Scholar), for studies discussing venous congestion and venous super-drainage in DIEP flap for breast reconstruction. Thirteen of the 35 articles compared results between one or two venous anastomoses. Meta-analysis was performed following PRISMA guidelines. Pooled risk ratio (RRs) for congestion, fat necrosis, partial necrosis, and total necrosis with corresponding 95% confidence intervals (CI) were calculated using a fixed-effect model with the Mantel-Haenszel method. The need to return to surgery (95% CI) was estimated with a random effect model using the DerSimonian and Liard method. RESULTS: We showed a statistically significant advantage of super-drainage to reduce the venous congestion of the flap (RR: 0.12, 95% CI: 0.04-0.34, p-value <.001), partial flap necrosis (RR: 0.50, 95% CI: 0.30-0.84, p-value .008), total flap necrosis (RR: 0.31, 95% CI: 0.11-0.85, p-value .023), and the need to take the patient back to surgery for perfusion-related complications (RR: 0.45, 95% CI: 0.21-0.99, p value .048). CONCLUSIONS: Performing a second venous anastomosis between the SIEV and a recipient vein (venous superdrainage) reduces venous congestion and related complications in DIEP flaps for breast reconstruction.

RESUMEN

BACKGROUND: Over the last few years, advances in technologies and digital imaging have led to the introduction of systems that enable a new approach to microsurgery and supermicrosurgery. The exoscope is a new magnification system that provides a 3D image of the surgical field: microsurgical procedures can be performed with the aid of this instrument. Here, we describe our preliminary experience with a high-definition 3D exoscope (VITOM®, Karl Storz, Tuttlingen, Germany), evaluating the characteristics of the instrument, and also its use as a magnification device for microanastomosis training. METHODS: Six microsurgeons with various levels of experience were asked to perform three end-to-end anastomoses and two end-to-side anastomoses on latex vessel models, using, as a magnification system, the VITOM® 3D 4K exoscope. None of the surgeons involved had previous experience with the exoscope, with robotic surgery, with endoscopic surgery, nor with training simulators. RESULTS: The results of the reported evaluation of the tool's qualities, (VITOM Quality Assessment Tool) included: a good focusing of the surgical field; high image quality; strong luminance; good magnification; clear stereoscopy; and excellent freedom of movement. The exoscope proved to be user-friendly. A constant reduction in the time needed to perform the microsurgical anastomosis at each exercise was recorded. Among other advantages were the easy switching from the magnified image to the macroscopic view, superior ergonomics allowing a relaxed posture while performing the anastomosis, adequate space, and a convenient setting for the assistants to view the operating field. CONCLUSIONS: Our study showed that the exoscope VITOM 3D can be successfully used as a magnification tool for microsurgical anastomosis on synthetic vessels, and that it can also be helpful during training courses in microsurgery.

RESUMEN

Propeller flaps are local flaps based either on a subcutaneous pedicle, a single perforator, or vessels entering the flap in such a way so as to allow the flap to rotate on their axis. Depending on the kind of pedicle and the anatomical area, the preoperative investigation and the harvesting techniques may vary. An adequate knowledge of skin and subcutaneous tissue perfusion in the different areas of the body is very important to plan a propeller flap to be successful. The surgeon should begin by finding the most suitable perforators in the area surrounding the defect using available technology. The position, size, and shape of the flap are planned about this point. For perforator-pedicled propeller flaps, the procedure starts with an exploration from the margins of the defect or through a dedicated incision to visualize any perforators in the surroundings. The most suitable perforator is selected and isolated, the skin island is replanned, and the flap is harvested and rotated into the defect. The variations in surgical technique for other types of propellers and in specific anatomical areas are also described. Compared with free flaps, propeller flaps have the advantage of a simpler, shorter operation, without the need for a recipient vessel for microanastomosis. Yet, from a technical point of view, an adequate experience in dissecting perforators and the use of magnifying glasses are almost always required.

RESUMEN

The Covid 19 epidemic has modified the way that plastic surgeons can treat their patients. At our hospital all elective surgery was canceled and only the more severe cases were admitted. The outpatient department activity has been reduced also. We present the number and diagnoses of patients, treated as in- and out-patients, during seven weeks from the onset of the epidemic, comparing our activity from the lockdown of elective surgery with the numbers and diagnoses observed during the same weeks of last year. Finally we underline the importance of using telemedicine and web-based tools to transmit images of lesions that need the surgeon's evaluation, and can be used by the patient to keep in touch with a doctor during the distressing time of delay of the expected procedure.

RESUMEN

BACKGROUND: The goal of microsurgical breast reconstruction is to return to the precancer state, maximizing symmetry with less morbidity. This requires a long learning curve, in particular where modeling is concerned. In this context, reverse engineering technologies found an application, allowing the creation of molds that can be used during the surgery. METHOD: We created 10 molds named DIEP sizers, which help to simplify deep inferior epigastric perforator (DIEP) flap insetting. For this, we designed a virtual model using Geomagic X software to construct the sizers. Our model has a thorax circumference, breast projection, and footprint correspondent to an average of the measurements we collected from 15 patients undergoing such surgery. We made a comparative study between 2 groups each of 24 patients, using as comparison criteria surgical times in patients undergoing breast microsurgical reconstruction with or without DIEP sizers. In both groups, we included immediate and delayed reconstructions as well as monolateral, bilateral and monolateral with contralateral symmetrization. RESULT: In all the cases we performed with DIEP sizers, we achieved an average time saving of 105 minutes in monolateral reconstruction, 80 minutes in monolateral reconstruction with contralateral symmetrization, and 120 minutes in bilateral reconstruction (P < 0.001). No major complications occurred. CONCLUSIONS: We performed 24 breast reconstructions with preformed molds, obtaining a proper "library" with different DIEP sizers that can be used both in preoperative planning and in intraoperative modeling. We recommend the use of a preformed mold in microsurgical breast reconstruction to improve symmetry, to shorten the learning curve and to save time.

RESUMEN

Radiotherapy is essential for achieving and maintaining local control in head and neck rhabdomyosarcoma patients. However, radiotherapy may cause outgrowth disturbances of facial bone and soft tissue, resulting in facial asymmetry.Several studies have shown that the management of irradiated bones still remains challenging. The possibility of obtaining functional and aesthetic results when managing facial deformities due to radiation therapy with distraction osteogenesis combined with free flaps reconstruction is not common and not well documented in recent literature.In this report, we present the long-term results of distraction osteogenesis and soft tissue reconstruction via microvascular free flap to correct the facial hypoplasia of a young patient who underwent radiation therapy for rhabdomyosarcoma.This is the first presentation of 26 years long-term results in a patient who also underwent free flaps reconstruction as ancillary surgery for esthetic good results.

RESUMEN

INTRODUCTION: We present our pre-operative virtual planning of complex mandibular reconstruction with a microvascular fibular composite free flap and its harvesting using our novel cutaneous positioning guide based on the perforator vessels for our soft tissue reconstructive surgery. TECHNICAL REPORT: We applied our protocol to 42 consecutive patients needing mandibular composite reconstruction. All patients were preoperatively studied with a CTA scan to evaluate the fibular pattern of vascularization and the perforator vessels three-dimensional path and position. Computer assisted surgery (CAS) was performed: a skin paddle outlining guide (SPOG) was designed to reproduce the shape and area of the planned soft tissue resection. CTA measurements and in vivo findings were compared. After performing the CTA, we classified the viable perforators in High Perforators, Medium Perforators and Low Perforators. The average diameter of the perforator vessels was 3 mm. The average difference between the measurements performed on the CTA and the intra-operative measures was 1, 4 mm. The SPOG was based on calf proximal and distal diameters. The anatomical fitting of the guide was obtained thanks to two customized flanges that embrace circumferentially the proximal and distal portions of the leg. The SPOG encompassed appropriate skin/leg regions, allowing the surgeon to localise the required perforator vessel. CONCLUSIONS: CTA protocol appears to be a valuable approach to asses and virtually simulate composite mandibular reconstructions. The SPOG seems to be a valuable tool to reproduce intra-operatively the planned soft tissue area to be reconstructed.

RESUMEN

The CAD/CAM technology for mandibular reconstruction has improved the results in terms of outcomes in restoring mandibular complex defects. Augmented reality (AR) represents an evolution of the navigation-assisted surgery. This technology merges the images of the virtual planning with the anatomy of the patient, representing in this way an enhanced scene for the surgeon's eye. AR can also display in a single scene additional information for the surgeon. Despite of classical navigation, this scenario can be obtained with marker-less registration method, without using reference points or fiducial markers. This technologic evolution together with the large use in our experience of CAD/CAM protocol for mandibular reconstruction we developed this feasibility study to evaluate the possibility of using a marker-less image registration system. Moreover, we tried to evaluate the overlaying of the virtual planning and its reproducibility using AR. We performed a case series of 3 consecutive patients who underwent mandibular reconstruction using AR-assisted fibular free flap harvesting applying our digital workflow. Once launched, the mobile app installed on our tablet, the registration is performed according to a shape recognition system of the leg of the patient, rendering in real time a superimposition of the anatomy of the bony, vascular, and skin of the patient and also the surgical planning of the reconstruction. AR-assisted fibular free flap harvesting was performed. We believe that AR can be a prospective improving technology for mandibular complex reconstruction.

RESUMEN

BACKGROUND: Multicomponent defects of the head and neck involving the cervical skin pose a reconstructive challenge for microsurgeons and usually requires two flaps. However, many patients who undergo such surgical treatment had prior treatment with radiotherapy and the availability of recipient vessels for free flap reconstruction may be limited. The purpose of this study was to review our experience in the reconstruction of these extensive head and neck defects using a single ALT free flap. METHODS: A total of 21 patients with complex defects of the head and neck involving multiple anatomical subunits, including the overlying cervical skin, underwent reconstruction with a single ALT flap. The clinical, functional, and aesthetic outcomes of these patients were reviewed. RESULTS: The mean hospital stay was 24 days. There was one total flap loss due to pedicle thrombosis. The patient underwent a further ALT reconstruction with no postoperative complications. Cervical fistulas occurred in three patients, and all fistulas were healed by simple wound packing. Three patients with tracheal defect had a functional tracheostoma with adequate stomal patency. A modified barium swallowing study was performed on each patient, and all of them achieved total oral intake. Among them, two patients tolerated only a pureed diet. CONCLUSIONS: Complex neck reconstruction can be accomplished with a single ALT flap with good clinical and functional results, minimal morbidity and quick recovery.
