Perforator Branch-based Dissection for Ultrathin Anterolateral Thigh Free Flap for Tongue Reconstruction: A Preliminary ReportAffiliations
AbstractBackground: This study compared tongue reconstructions in hemiglossectomy patients using ultrathin free flaps with perforator branch-based dissection (PBD) versus conventional anterolateral thigh (ALT) subfascial free flaps. We aimed to evaluate the success rates and speech function outcomes of these techniques, focusing on managing flap thickness. Methods: A retrospective review of hemiglossectomy patients (2017-2023) was conducted, focusing on ultrathin subdermal perforator free flaps versus conventional ALT free flaps. Speech function, surgical details, and complications were assessed to compare outcomes. Speech intelligibility and articulation were analyzed using standardized tests. Results: Sixteen patients (mean age 49 [range 22-81] y) underwent tongue reconstruction with conventional or PBD ALT flaps. The PBD flap group had no debulking needs, whereas 3 conventional flap patients required it. Speech function analysis showed higher articulation (89.5% versus 80.5%) and intelligibility (100% versus 84.3%) in the PBD flap group. Conclusions: PBD for ultrathin ALT flaps in hemiglossectomy patients offers comparable functional outcomes to conventional ALT flaps, making PBD a viable alternative, despite the learning curve.
Supermicrosurgery in Reconstructive Surgery: A Narrative ReviewAffiliations
AbstractSupermicrosurgery, defined as the anastomosis of vessels smaller than 0.8 mm, represents a significant evolution in the field of reconstructive microsurgery. This review explores its technical foundations, clinical applications, and future directions, with a particular focus on lower extremity reconstruction. By utilizing perforator-to-perforator anastomosis and thin flap techniques, supermicrosurgery allows for reduced donor morbidity, minimized risk to major vessels, and improved aesthetic and functional outcomes. The integration of high-frequency ultrasonography and advanced microsurgical tools has enhanced preoperative planning and intraoperative precision. Despite a steep learning curve, supermicrosurgery is increasingly applied in oncologic, traumatic, ischemic, and diabetic foot reconstructions. Continued innovation in imaging, instrumentation, and robotic assistance suggests a promising future for this subspecialty. Keywords: high-frequency ultrasound; perforator flap; robotic microsurgery; superficial plane; supermicrosurgery.
The Current Landscape of Robotics in Lymphatic Supermicrosurgery: A Systematic ReviewAffiliations
AbstractBackground: Lymphedema affects over 250 million people worldwide and is increasingly managed with physiologic procedures such as lymphovenous bypass (LVB) and vascularized lymph node transfer (VLNT). These supermicrosurgical techniques require advanced training, are ergonomically demanding, and can be limited in anatomically constrained regions. Robotic surgical systems offer high-resolution visualization, motion scaling, tremor reduction, and improved ergonomics, making them promising adjuncts for lymphatic supermicrosurgery. However, evidence on safety, feasibility, and outcomes remains limited. Methods: A systematic review was conducted in accordance with PRISMA guidelines using PubMed, Cochrane Library, and Embase from inception through December 2024. Eligible studies included human clinical reports of robotic-assisted peripheral lymphatic reconstruction. Extracted data included demographics, operative details, outcomes, and study quality. Results: Seven studies involving 134 patients and 221 anastomoses were included, of which 78% (172) were performed robotically. The Symani system was most frequently used. Robotic procedures comprised 59.9% LVBs and 32% VLNTs or other free flaps. Across studies, mean anastomotic time was longer with robotic assistance (25.7 minutes) compared with manual techniques (11 minutes); however, three studies demonstrated significant time reduction with experience, ultimately approaching manual times. When reported, clinical outcomes, including limb volume reduction and quality-of-life measures, were comparable between robotic and manual groups. Advantages included tremor elimination and improved ergonomics, while challenges included cost, setup time, and lack of haptic feedback. Conclusions: Robotic-assisted lymphatic supermicrosurgery is safe and feasible, with outcomes comparable to conventional surgery. Continued refinement, cost reduction, and standardized outcome reporting will determine its role in expanding therapeutic and preventive lymphatic reconstruction. Keywords: MUSA; Symani; lymphatic surgery; robotic-assisted lymphatic surgery; robotic-assisted microsurgery.
Prospective Observational Study of Supercritical Carbon Dioxide-Processed Acellular Dermal Matrix in Implant-Based Breast ReconstructionAffiliations
AbstractBackground: Conventional detergent-based decellularization can disrupt the extracellular matrix (ECM) structure and denature proteins. Supercritical carbon dioxide (scCO 2 ) processing offers a simplified manufacturing process (<2 hours), minimal protein denaturation, and excellent ECM preservation. This study aimed to evaluate the clinical outcomes of scCO 2 processing acellular dermal matrix (ADM) compared with conventional detergent-processed ADM. Methods: This prospective observational study enrolled patients undergoing immediate implant-based breast reconstruction with scCO 2 -processed ADM ( n = 50) and compared outcomes with a retrospective cohort receiving conventional detergent-processed human ADM ( n = 50). Patient demographics, comorbidities, and treatment variables were collected. Postoperative complications and BREAST-Q-assessed patient-reported outcomes were analyzed. Results: The groups were comparable in age (45.0 ± 10.4 years vs. 46.8 ± 9.4 years, p = 0.362), body mass index (median: 21.5 kg/m 2 vs. 22.7 kg/m 2 , p = 0.558), comorbidities, and oncologic characteristics. Rates of skin necrosis (2% vs. 0%), nipple-areolar complex necrosis (2% vs. 2%), hematoma (4% vs. 4%), seroma (6% vs. 0%), infection (6% vs. 0%), capsular contracture (8% vs. 12%), implant failure (0% vs. 0%), implant change (2% vs. 2%), and reoperation (2% vs. 2%) did not differ significantly between groups. BREAST-Q questionnaires revealed no significant differences in patient-reported outcomes. Conclusion: scCO 2 -processed ADM demonstrated safety and patient-reported outcomes equivalent to established detergent-based ADMs. Given its eco-friendly, protein-preserving manufacturing process, scCO 2 -processed ADM represents a safe and effective alternative for implant-based breast reconstruction. Long-term follow-up studies are warranted. Keywords: acellular dermal matrices; acellular dermal matrix; breast; breast reconstruction with prosthetic devices; implant-based breast reconstruction; supercritical carbon dioxide processing.
Chronological Changes in Breast and Nipple Position After Autologous Reconstruction in an Asian PopulationAffiliations
AbstractThe breast shape changes between reconstructed and native breasts in autologous reconstruction, which is important to achieve symmetry. This study was conducted to clarify chronological changes in the shape and nipple position of the reconstructed breast compared with the contralateral breast in the Asian population.Photographic assessments were conducted at baseline and during annual visits of patients who underwent immediate free flap breast reconstruction following unilateral nipple-sparing mastectomy at our institution between June 2017 and December 2019. Univariate and multivariate analyses were performed to identify factors associated with the change in shape and nipple position. This observation was most marked at 1-year postsurgery.Among the 170 patients (mean age, 48.04 ± 7.55 years), 164 (96.47%) had a deep inferior epigastric perforator flap and 8 (4.71%) required further surgery on the contralateral breast for correction of asymmetry. The chronological changes in the breast shape and nipple position significantly differed between the native and the reconstructed breast, with the latter showing a higher degree of retraction. Grading of breast ptosis (grades 0-2) and exposure to radiotherapy were associated with an increased degree of retraction.Retraction may occur after free flap breast reconstruction, particularly in patients with ptosis or those receiving radiotherapy. These findings support careful planning, including volume adjustment and contralateral procedures. While based on an Asian population, the results may inform surgical decisions in similar patient groups.
