Autologous Breast Reconstruction and Radiotherapy: Consensus Report of the German-Speaking Society for Reconstructive Microsurgery (GSRM)

Autologous postmastectomy breast reconstruction is associated with favourable long-term clinical outcomes and superior patient-reported outcomes (PROMs) compared with implant-based reconstruction. However, adjuvant radiotherapy has traditionally been considered a relative contraindication to immediate flap-based reconstruction due to its unpredictable effects on the reconstructive outcome. While modern adjuvant postmastectomy radiotherapy (PMRT) has been able to significantly reduce acute and chronic radiation-induced complications, plastic surgeons still hesitate to offer immediate autologous reconstruction to patients expected to undergo adjuvant radiotherapy. More recently, evidence has emerged suggesting a paradigm shift in favour of immediate autologous reconstruction despite subsequent radiotherapy. At the 44th Annual Meeting of the German-speaking Society for Reconstructive Microsurgery (GSRM) in Bern, Switzerland, a workshop discussed the literature on PMRT and autologous breast reconstruction, aiming to establish consensus among the participants. Several areas of agreement were identified, including the goals of postmastectomy reconstruction, specifically the creation of a soft and sensitive breast symmetrical in shape and size to the unaffected breast via the safest procedure possible. The importance of preserving the maximum amount of native breast skin envelope through skin- and nipple-sparing approaches was emphasised. Finally, a consensus was reached that PMRT should no longer be considered a contraindication to immediate autologous breast reconstruction.

Pelvic and Perineal Reconstruction.

After studying this article, the participant should be able to: 1. Classify types of bony pelvic resections. 2. Outline reconstructive options for pelvic and perineal defects. 3. Identify advantages and drawbacks of various reconstructive techniques. 4. Recognize the functional benefits of bony and soft-tissue reconstruction. Defects of the pelvis and perineum arise from tumors, trauma, infection, congenital differences, and gender incongruence. Pelvic resections can result in bony instability and soft-tissue deficiency. The goals of reconstruction are maintenance of spinopelvic continuity, elimination of dead space, resurfacing of cutaneous defects, and prevention of hernias. Perineal reconstruction has important functional considerations. Abdominoperineal resection and pelvic exenteration defects benefit from flap reconstruction to decrease pelvic wound complications. Vulvovaginal reconstruction is performed with flaps from the perineum, thigh, or abdomen. Scrotal and superficial penile defects are most commonly reconstructed with scrotal flaps and skin grafts. Total penile reconstruction most commonly uses a radial forearm free flap.

Metric learning guided sinogram denoising for cone beam CT enhancement.

Cone beam computed tomography (CBCT) is a widely available modality, but its clinical utility has been limited by low detail conspicuity and quantitative accuracy. Convenient post-reconstruction denoising is subject to back projected patterned residual, but joint denoise-reconstruction is typically computationally expensive and complex. In this study, we develop and evaluate a novel Metric-learning guided wavelet transform reconstruction (MEGATRON) approach to enhance image domain quality with projection-domain processing. Projection domain based processing has the benefit of being simple, efficient, and compatible with various reconstruction toolkit and vendor platforms. However, they also typically show inferior performance in the final reconstructed image, because the denoising goals in projection and image domains do not necessarily align. Motivated by these observations, this work aims to translate the demand for quality enhancement from the quantitative image domain to the more easily operable projection domain. Specifically, the proposed paradigm consists of a metric learning module and a denoising network module. Via metric learning, enhancement objectives on the wavelet encoded sinogram domain data are defined to reflect post-reconstruction image discrepancy. The denoising network maps measured cone-beam projection to its enhanced version, driven by the learnt objective. In doing so, the denoiser operates in the convenient sinogram to sinogram fashion but reflects improvement in reconstructed image as the final goal. Implementation-wise, metric learning was formalized as optimizing the weighted fitting of wavelet subbands, and a res-Unet, which is a Unet structure with residual blocks, was used for denoising. To access quantitative reference, cone-beam projections were simulated using the X-ray based Cancer Imaging Simulation Toolkit (XCIST). In both learning modules, a data set of 123 human thoraxes, which was from Open-Source Imaging Consortium (OSIC) Pulmonary Fibrosis Progression challenge, was used. Reconstructed CBCT thoracic images were compared against ground truth FB and performance was assessed in root mean square error (RMSE), peak signal-to-noise ratio (PSNR), and structural similarity index (SSIM). MEGATRON achieved RMSE in HU value, PSNR, and SSIM were 30.97±4.25, 37.45±1.78, and 93.23±1.62, respectively. These values are on par with reported results from sophisticated physics-driven CBCT enhancement, demonstrating promise and utility of the proposed MEGATRON method. We have demonstrated that incorporating the proposed metric learning into sinogram denoising introduces awareness of reconstruction goal and improves final quantitative performance. The proposed approach is compatible with a wide range of denoiser network structures and reconstruction modules, to suit customized need or further improve performance.

Direct Anterior Total Hip Arthroplasty with VELYS™ Hip Navigation.

We describe the technique of total hip arthroplasty via a direct anterior approach using the Depuy Synthes (Raynham, MA) VELYS™ Hip Navigation system This technique allows one to accurately set the acetabular component position as well as recreate leg length and offset to meet the goals of hip reconstruction in a precise and efficient manner.

Relief, rescue and reconstruction: Shanghai’s Jewish child refugees in JDC photography

ABSTRACT This paper focuses on humanitarian photography taken of Jewish child refugees, who fled to Shanghai from various European countries during the Holocaust. Specifically, the paper will discuss photographs taken by the American Jewish Joint Distribution Committee (JDC) in the 1940s. This paper will argue that these photographs serve a dual function, depicting the children as both the future of the Jewish people and also proof of the need for future JDC work. In doing so, the paper seeks to understand how these photographs complemented (or deviated from) the organization’s goals of rescue, relief and reconstruction, known as the ‘three Rs’.

Multi-flap reconstruction for a recurrent giant phyllodes tumor

Few case reports have discussed the incidence and management of giant recurrent phyllodes tumors with borderline to malignant features. We report that of a recurrent case in a 57-year-old female who underwent wide excision with en bloc resection of the 3rd to 7th right anterior ribs and upper abdominal wall. Rigid chest wall reconstruction was achieved using methyl methacrylate and synthetic mesh. This is the first reported case wherein three locoregional flaps, namely the latissimus dorsi, thoracoepigastric and extended external oblique flaps were used to cover a defect measuring 1452 cm2 in size. With this combination of flaps, deformity was minimized, and the resultant outcome was aesthetically and functionally acceptable. Reconstructive goals of intrathoracic organ protection, restoration of chest wall rigidity, maintenance of adequate respiratory function and soft tissue closure were achieved. Careful planning and individualized treatment together with multidisciplinary collaboration remains vital in the successful management of large recurrent malignant phyllodes tumors.

Prefabricated Fibula Flap vs Bone-Driven and Delayed Implant Installation for Jaw Reconstruction

Restoration of dental occlusion and oral rehabilitation is the ultimate goal of functional jaw reconstruction. To evaluate the prefabricated fibula flap (PFF) technique in occlusion-driven jaw reconstruction for benign or previously treated malignant disease. This cohort study was conducted from January 2000 to December 2019 at the University of Alberta Hospital and Institute of Reconstructive Sciences in Medicine in Edmonton, Alberta, Canada, among patients who underwent PFF or bone-driven and delayed osseointegrated implant installation (BDD). Patients were followed up for a minimum of 1 year after occlusal rehabilitation. Data were analyzed from July 2021 to June 2022. Patients underwent BDD or PFF, which consists of osseointegrated dental implant installation and skin grafting of the fibular bone 3 to 6 months before jaw tumor resection or defect reconstruction. The implant osseointegration is completed at the time of jaw reconstruction, allowing for full reconstruction, loading, and restoration of the dental occlusion in the immediate postoperative period. Safety, effectiveness, accuracy, timeliness of occlusal reconstruction, and aesthetic appeal were compared between PFF and BDD. Groups were compared for the following variables: postoperative complications, number of bony segments used, number of procedures needed, total operative time, time to occlusal rehabilitation, and number of implants installed, exposed, lost, and used (ie, exposed implants - lost implants). Aesthetic appeal was assessed using standardized full-face and profile digital photographs taken before and 6 to 12 months after the operation and analyzed by 3 naive raters. Among 9 patients receiving PFF (mean [SD] age, 43.3 [13.0] years; 7 men [77.8%]) and 12 patients receiving BDD (mean [SD] age, 41.9 [18.0] years; 8 men [66.7%]), the overall complication rate was similar (4 patients [44.4%] vs 3 patients [25.0%], respectively; relative risk, 1.78 [95% CI, 0.52 to 6.04]). The number of patients with implant loss was similar between PFF and BDD groups (0 patients vs 3 patients [25.0%], respectively; difference, -25.0 percentage points [95% CI, -48.4 to 9.7 percentage points]). PFF had a clinically meaningful faster mean (SD) occlusal rehabilitation compared with BDD (12.1 [1.9] months vs 60.4 [23.1] months; difference, -48.3 months [95% CI, -64.5 to -32.0 months]). The mean (SD) difference in preoperative to postoperative aesthetic score was similar between PFF and BDD groups (-0.8 [1.5] vs -0.2 [0.8]; difference, -0.6 [95% CI, -1.6 to 0.4]). This study found that PFF compared with BDD was a safe, effective, and aesthetic reconstructive option for patients with benign or previously treated jaw malignant tumors. This technique may provide rapid occlusal reconstruction and oral rehabilitation.

Delayed Orbital Floor Reconstruction Using Mirroring Technique and Patient-Specific Implants: Proof of Concept.

Enophthalmos is a severe complication of primary reconstruction following orbital floor fractures, oncological resections, or maxillo-facial syndromes. The goal of secondary orbital reconstruction is to regain a symmetrical globe position to restore function and aesthetics. In this article, we present a method of computer-assisted orbital floor reconstruction using a mirroring technique and a custom-made titanium or high-density polyethylene mesh printed using computer-aided manufacturing techniques. This reconstructive protocol involves four steps: mirroring of the healthy orbit computer tomography files at the contralateral affected site, virtual design of a customized implant, computer-assisted manufacturing (CAM) of the implant using Direct Metal Laser Sintering (DMLS) or Computer Numerical Control (CNC) methods, and surgical insertion of the device. Clinical outcomes were assessed using 3dMD photogrammetry and computed tomography measures in 13 treated patients and compared to a control group treated with stock implants. An improvement of 3.04 mm (range 0.3-6 mm) in globe protrusion was obtained for the patients treated with patient-specific implants (PSI), and no major complications have been registered. The technique described here appears to be a viable method for correcting complex orbital floor defects needing delayed reconstruction.

Vitamin D as an intervention for improving quadriceps muscle strength in patients after anterior cruciate ligament reconstruction: study protocol for a randomized double-blinded, placebo-controlled clinical trial

BackgroundThe goal of anterior cruciate ligament reconstruction (ACLR) is to restore the preinjury level of knee function to return to play (RTP). However, even after completing the rehabilitation programme, some patients may have persistent quadriceps muscle weakness affecting knee function which ultimately leads to a failure in returning to play. Vitamin D has been long recognized for its musculoskeletal effects. Vitamin D deficiency may impair muscle strength recovery after ACLR. Correcting vitamin D levels may improve muscle strength.MethodsThis is a double-blinded, randomized controlled trial to investigate the effects of vitamin D supplementation during the post-operative period on quadriceps muscle strength in anterior cruciate ligament (ACL)-injured patients. Patients aged 18–50 with serum vitamin D < 20 ng/ml, unilateral ACL injury, > 90% deficit in total quadriceps muscle volume on the involved leg compared with uninvolved leg, Tegner score 7 + , and no previous knee injury/surgery will be recruited. To assess patient improvement, we will perform isokinetic and isometric muscle assessments, ultrasound imaging for quadriceps thickness, self-reported outcomes, KT-1000 for knee laxity, biomechanical analysis, and Xtreme CT for bone mineral density. To investigate the effect of vitamin D status on quadriceps strength, blood serum samples will be taken before and after intervention.DiscussionPatients with low vitamin D levels had greater quadriceps fibre cross-sectional area loss and impaired muscle strength recovery after ACL. The proposed study will provide scientific support for using vitamin D supplementation to improve quadriceps strength recovery after ACLR.Trial registrationClinicalTrials.gov NCT05174611.

War, Politics, and Change

Historians have long documented the ways in which war and politics bring about social, economic, and cultural change. Nowhere is this more evident than during the American Civil War and Reconstruction. The war devastated the South; it upended the system of chattel slavery and instigated remarkable transformations to the region’s demographics, political, and economic structures. Reconstruction emerged out of the ashes of war. This critical and hotly debated period redefined U.S. citizenship, expanded suffrage rights, and altered the relationship between the federal government and the states. Many of the lofty goals of Reconstruction, however, fell short as southern “Redeemers” regained political power and enshrined a new system of white supremacy. While many of the changes during this era were structural, individuals also experienced personal metamorphoses. Each of the manuscripts reviewed in this issue explore these various transformations, shedding new light on military command and contingency, national and regional politics, and individual struggles as the American nation navigated disorienting change during these fateful years.

Utilizing the Subunit Concept to Achieve Better Outcomes in Lower Limb Reconstruction: A Clinical Experience in an Asian Population.

The goals of reconstruction have progressed from filling a defect to enhancing function and aesthetic appearance. We aimed to achieve better aesthetic and functional outcomes in terms of shoe fitting and mobility. This is accomplished via a classification of the subunits and aesthetic considerations of the lower limb. Between April 2017 and December 2021, 66 cases of lower extremity free fasciocutaneous flap reconstruction cases were included in this retrospective study. Data parameters include age, sex, comorbidities, etiology of lower limb wounds, choice of free flap reconstruction, recipient arterial vessels, complications of flap reconstruction, and need for secondary debulking procedures. Physiotherapy records were also examined to determine the time to independent ambulation. In total, 66 subjects were identified. The mean age was 48.6. An estimated 74.2% (n = 49) were men, 50% (n = 33) had diabetes, and 16.6% (n = 11) had peripheral vascular disease. Of the total wounds, 65.1% (n = 43) were caused by infection, whereas the remaining 34.9% (n = 23) were due to trauma. Of the cases, 72.7% (n = 48) had free anterolateral thigh flap reconstruction, 25.8% (n = 17) were reconstructed with superficial circumflex iliac artery perforator flaps, and 1.5% (n = 1) was reconstructed with medial sural artery perforator flaps. Cases that required secondary debulking procedures comprised 7.6% (n = 5). Free fasciocutaneous flaps are useful in lower extremity reconstruction. Based on the subunit principle and aesthetic considerations for lower limb reconstruction, it can aid in optimizing functional rehabilitation and decreasing secondary procedures.

A Distant Fasciocutaneous Chest Wall Skin Flap for Necrotic Finger Post Reimplantation: A Case Report

The hand is often compromised by scars or potentially necrotic wounds. Complete loss of index finger will result in impairment of 20% of hand and 11% of whole-person. One of the most influential factors in consideration of tissue loss are defect size, site, depth, and orientation. In our case study, a 16-year-old male presented with sensations of tingling and pain in his finger subsequent to an accidental laceration. Examination revealed a necrotic wound located on the distal phalanx of the index finger, accompanied by mild atrophy and discoloration. Subsequently, the patient underwent graft harvesting from the right chest wall flap, followed by primary closure of the donor site on the right chest wall. Upon a three-month follow-up, the patient expressed satisfaction, demonstrating proficient daily activities despite the injury being localized to the left hand. Utilizing a chest wall flap is less prevalent than employing regional or free flaps. Anterior chest wall flaps are specifically crafted on the anterolateral chest wall or within the infraclavicular region. The choice of a chest wall flap was determined to offer a less cumbersome graft and aligns with the patient's preference. The main goal of soft tissue reconstruction is to restore functionality, encompassing tasks such as exploration, sensation, and manipulation of objects, while simultaneously preserving the original length. Nonetheless, achieving this goal remains a complex challenge. Keywords: Necrotic finger, Reimplantation, Chest Wall Skin Flap, Soft Tissue Reconstruction

Expanding the Armamentarium of Donor Sites in Microvascular Head and Neck Reconstruction.

The field of microsurgical head and neck reconstruction has witnessed tremendous advancements in recent years. While the historic goals of reconstruction were simply to maximize flap survival, optimizing both aesthetic and functional outcomes has now become the priority. With an increased understanding of perforator anatomy, improved technology in instruments and microscopes, and high flap success rates, the reconstructive microsurgeon can push the envelope in harvesting and designing the ideal flap to aid patients following tumor extirpation. Furthermore, with improvements in cancer treatment leading to improved patient survival and prognosis, it becomes increasingly important to have a broader repertoire of donor sites. The present review aims to provide a review of newly emerging soft tissue flap options in head and neck reconstruction. While certainly a number of bony flap options also exist, the present review will focus on soft tissue flaps that can be harvested reliably from a variety of alternate donor sites. From the upper extremity, the ulnar forearm as well as the lateral arm, and from the lower extremity, the profunda artery perforator, medial sural artery perforator, and superficial circumflex iliac perforator flaps will be discussed, and we will provide details to aid reconstructive microsurgeons in incorporating these alternative flaps into their armamentarium.

Scalp and Dural Reconstruction With a Tensor Fascia Lata Myofascial and Anterolateral Thigh Fasciocutaneous Chimeric Flap: A Case Report

Composite scalp and cranial defects present a challenge due to the unique elements that need to be reconstructed. The goals of reconstruction are to protect intracranial contents, prevent cerebrospinal fluid leak (CSF) and infection, and to provide durable soft tissue coverage. We present a case of an immunocompromised patient with history of craniotomy who developed osteomyelitis and a cranial abscess resulting in a composite defect with dural, bony, and soft tissue loss. To achieve vascularized watertight dural repair and durable soft tissue coverage for resolution of infection and eventual staged cranioplasty, we performed a free tensor fascia lata (TFL) myofascial and anterolateral thigh (ALT) fasciocutaneous chimeric flap. The patient healed well without CSF leak or infection at 5-month follow-up and cranioplasty is planned. Use of a chimeric TFL and ALT flap is effective in the treatment of large, composite cranial defects in the setting of active infection.

Skull Base Reconstruction by Subsite after Sinonasal Malignancy Resection.

Reconstruction after the resection of sinonasal malignancies is complex and primarily dependent on the defect size and location. While the reconstructive paradigm for sellar mass resection is well delineated, the challenges associated with reconstruction after sinonasal malignancy resection are less well described. This narrative review will address the goals of reconstruction after both endonasal endoscopic and open sinonasal malignancy resection and reconstructive options specific to these subsites. The goals of reconstruction include repairing cerebrospinal fluid leaks, restoring sinonasal function, providing a nasal airway, and optimizing the patient's quality of life. These goals are often complicated by the anatomic nuances of each involved sinus. In this review, we will discuss the methods of reconstruction specific to each sinonasal subsite and describe the factors that guide choosing the optimal reconstructive technique.

Cranio-Orbital Oncoplastic Reconstruction in Pediatric Population: Single-Institution’s Experience of 10 Cases

Background: Pediatric cranio-orbital tumors have several etiologies and given the broad spectrum of pathology, it is difficult to predict the extent of resection. Reconstruction in children and adolescents is particularly challenging due to potential craniofacial growth and the relatively limited availability of donor sites. In this review, we analyze 10 pediatric and adolescent cases from a single institution, discuss the existing literature, and propose a reconstruction algorithm for managing these complex defects. Methods: A retrospective chart review was performed to identify pediatric and adolescent patients with cranio-orbital tumors who underwent tumor resection and reconstruction at our institution between January 2012 and July 2022. Results: A total of 10 patients underwent oncoplastic reconstruction of defects of either the cranium alone or combination of cranium and orbit, with a mean age of 12.4 years (range: 2-20). The defects involved the parietal (n = 3, 30%), parietooccipital (n = 1; 10%), temporoparietal (n = 1; 10%), occipital (n = 1, 10%), and fronto-orbital (n = 4; 40%) regions. Cranioplasty was performed with split-thickness bone grafts, exchange cranioplasty, or alloplastic materials. A pericranial flap was used to isolate intracranial and extracranial contents in 2 cases. Free flaps were utilized for additional soft tissue coverage in 2 cases. Complications included free flap venous thrombosis, CSF leak, hardware exposure, sagittal sinus injury, superior sagittal sinus thrombosis, vertical diplopia, and hypertropia. Conclusion: The goals of oncoplastic reconstruction for cranio-orbital defects in pediatric and adolescent patients align with those in adults. However, reconstructive surgeons must consider age-specific differences, such as growth potential and limited donor sites. Effective reconstruction can be achieved through meticulous planning, clear communication, and a multidisciplinary approach.

Study of Various Modalities of Management of Lower One-third Leg Defects in a Tertiary Care Hospital

Background: Lower extremity reconstruction is essential to plastic surgery and focuses on treating wounds and defects secondary to trauma, cancer, or chronic disease processes. Anatomical features of the lower third of the leg like subcutaneous bone surrounded by tendons with no muscles and vessels in isolated compartments with little intercommunication between them make the coverage of the wounds in the region a challenging problem. Aim: to study the various modalities of surgical management of lower 1/3rd leg defects. The study also aims to study the defect size and region in planning various flaps possible in the reconstruction ladder. Methods: The study was conducted from September 2014 to June 2017 on patients admitted to the Department of Burns, Plastic &amp; Reconstructive Surgery and referred patients from the Department of General Surgery &amp; Orthopaedic Surgery, S C B Medical College &amp; Hospital, Cuttack. The Study includes all lower 3rd Leg defect varieties for different surgical treatment modalities. Results: Various reconstructive methods were used to cover the lower 1/3rdleg defects; the maximum was the free muscle transfer in 9 cases. The following typical flap used was the reverse sural flap. Conclusion: The goal in lower limb reconstruction involves needing a stable skeleton, allowing weight-bearing status, with adequate soft tissue coverage to nourish and protect the underlying bone. What one would use for reconstruction depends upon the surgeon’s familiarity and comfort levels with the technique as much as the various circumstances.

Key events that reshaped the public procurement paradigm globally are outlined. The paper provides detailed characterization of leading electronic platforms for public procurement, highlighting their features, advantages, and drawbacks. The public procurement systems in Ukraine and the European Union are compared, outlining directions for harmonizing Ukrainian legislation with European standards and best practices. Key issues and potential ways to improve the procurement system to reduce corruption levels are outlined. The World Bank's recommendations on using Ukraine's Prozorro electronic system for all procurement needs for the country's reconstruction after the full-scale invasion by Russia are highlighted. The prospects of adapting Prozorro to the World Bank's specific standards and reconstruction needs, particularly regarding the procurement of consulting, design, and architectural works, are considered. The study underscores the utmost importance of continuous improvement of Ukraine's public procurement system, incorporating global best practices, implementing innovations, enhancing workforce qualifications, and adhering to principles of transparency and integrity. Only through reform can effective use of budgetary funds and ambitious goals of the country's reconstruction be achieved.

Body Contour in the Post-Bariatric Male Patient

Background: Obesity is currently considered a public health problem. Bariatric procedures have become an important part of obesity management and, consequently, the number of male patients seeking post-bariatric reconstructive procedures have increased. Therefore, the clinical approach and understanding of the body contour of this population have become more relevant. The goal of post-bariatric reconstruction is to enhance the male silhouette through removal of skin and adipose tissue excess, and abdominal rectus diastasis repair. Material and Methods: We conducted a retrospective study at the Plastic and Reconstructive Surgery Department of the National Medical Center “20 de Noviembre”. All male patients referred to our department to start a post-bariatric reconstruction protocol from January 2018 to December 2022 were included in this study. Results: In total, 15 patients who underwent corporal contouring procedures were included; median age was 49.2 years with minimum of 33 years, and a maximum of 57 years. Median Body mass index was 28.4 kg/m2 with minimum of 22 kg/m2 and maximum of 38 kg/m2 . All patients were treated 18 months after their bariatric surgery. All patients underwent an abdominoplasty as a body contouring procedure. 4 (26.7%) patients presented complications related to the surgery. Conclusion: We propose a comprehensive and systematic approach to massive weight loss for male patients, suggesting an abdominal marking based on the patient's clinical features and the expected results avoiding feminization of the abdominal body contour.

3D Reconstruction with Spherical Cameras

The goal of image-based 3D reconstruction is to establish a high-quality 3D expression from images. In order to achieve a high-resolution and real-time 3D model, inspired by the open source COLMAP, we propose a novel framework (3DMAP) to reconstruct 3D scenes based on spherical cameras. Unlike traditional methods which focus on building a 3D plane by Poisson distribution function, our method illustrates the key processes of 3D reconstruction: locating the camera based on global feature, estimating the scene’s relative depth from monocular panoramic images, and obtaining a high-quality 3D surface reconstruction. In the camera locating part, we use a global descriptor augmentation model to build a labeled panorama dataset GDAP, in which the images are captured by our designed spherical cameras; In the depth estimation part, we propose a new network UMDE that can estimate the depth of both indoor and outdoor scenes; Finally, in the 3D surface reconstruction section, we turn the reconstruction problem to a graph optimization problem, called GraphFit, in which, we optimize the point clouds with s-t graph and smoothing method successively. We conduct experiments on our own dataset to demonstrate the effectiveness of our proposed 3DMAP framework. Experimental results show that our 3DMAP has achieved good evaluation scores and visual effects.
