Evaluating Operative Times for Intraoperative Conversion of Axillary Node Biopsy to Axillary Lymph Node Dissection with Immediate Lymphatic Reconstruction.

BACKGROUND: Lymphedema can occur in patients undergoing axillary lymph node dissection (ALND) and radiation for breast cancer. Immediate lymphatic reconstruction (ILR) is performed to decrease the risk of lymphedema in patients after ALND. Some patients who ultimately require ALND are candidates for attempted sentinel lymph node biopsy (SLNB) or targeted axillary excision. In those scenarios, ALND can be performed (1) immediately if frozen sections are positive or (2) as a second operation following permanent pathology. The purpose of this study is to evaluate immediate ALND/ILR following positive intraoperative frozen sections to guide surgical decision-making and operative planning. METHODS: A single-center retrospective review was performed (2019-2022) for breast cancer patients undergoing axillary node surgery with breast reconstruction. Patients were divided into two groups: immediate conversion to ALND/ILR (Group 1) and no immediate conversion to ALND (Group 2). Demographic data and operative time were recorded. RESULTS: There were 148 patients who underwent mastectomy, tissue expander (TE) reconstruction, and axillary node surgery. Group 1 included 30 patients who had mastectomy, sentinel node/targeted node biopsy, TE reconstruction, and intraoperative conversion to immediate ALND/ILR. Group 2 had 118 patients who underwent mastectomy with TE reconstruction and SLNB with no ALND or ILR. Operative time for bilateral surgery was 303.1 ± 63.2 minutes in Group 1 compared with 222.6 ± 52.2 minutes in Group 2 (p = 0.001). Operative time in Group 1 patients undergoing unilateral surgery was 252.3 ± 71.6 minutes compared with 171.3 ± 43.2 minutes in Group 2 (p = 0.001). CONCLUSION: Intraoperative frozen section of sentinel/targeted nodes extended operative time by approximately 80 minutes in patients undergoing mastectomy with breast reconstruction and conversion of SLNB to ALND/ILR. Intraoperative conversion to ALND adds unpredictability to the operation as well as additional potentially unaccounted operative time. However, staging ALND requires an additional operation.

Oxylipins in Breast Implant Associated Systemic Symptoms.

BACKGROUND: A subset of women with breast implants have reported a myriad of nonspecific systemic symptoms collectively termed systemic symptoms associated with breast implants (SSBI). SSBI symptoms are similar to manifestations associated with autoimmune and connective tissue disorders Breast tissue is rich in adipose cells, comprised of lipids. Insertion of an implant creates an oxidative environment leading to lipid oxidation. Oxylipins can influence immune responses and inflammatory processes. OBJECTIVES: This study explores the abundance of a spectrum of oxylipins in the peri-prosthetic tissue surrounding the breast implant. Since oxylipins are immunogenic, we sought to determine if they are associated with the SSBI subjects. We have also attempted to determine if the common manifestations exhibited by such subjects have any association with oxylipin abundance. METHODS: The study included 120 subjects divided in three cohorts. Forty-six subjects with breast implants exhibiting manifestation associated with SSBI, 29 in control cohort I subjects with breast implants not exhibiting manifestation associated with SSBI (non-SSBI) and 45 in control cohort II subjects without implants (normal tissue) were analyzed. Lipid extraction and oxylipin quantification was performed using LCMS. LC-MS/MS targeted analysis from the breast adipose tissue was performed. RESULTS: Of the fifteen oxylipins analyzed, four exhibited increased abundance in the SSBI cohort compared to the non-SSBI and normal cohorts. CONCLUSIONS: The study documents the association of the oxylipins with each manifestation reported by the subject. This study provides an objective assessment on the subjective questionnaire highlighting which symptoms could be more relevant than the others.

Revisiting Bipedicled Flaps for Lower Extremity Distal Third Defects.

BACKGROUND: Lower extremity reconstruction of the distal third of the leg is challenging. Free tissue transfer is the criterion standard. The COVID-19 pandemic encouraged seeking alternatives for resource consuming procedures. Bipedicled flaps are flaps with a dual-source subdermal perfusion. The purpose of this study was to assess outcomes of patients who had bipedicled flaps primary or auxiliary local flap for distal third leg/foot reconstruction. METHODS: A retrospective review of patients undergoing lower extremity reconstruction (2020-2021) was performed. Inclusion criteria were patients older than 18 years with lower extremity wounds secondary to traumatic injury for which bipedicled flaps were used in the reconstruction. Exclusion criteria included lower extremity wounds secondary to peripheral vascular disease or diabetes. RESULTS: Fourteen patients were included in the study. All patients had distal third of the leg/foot wounds, and 12 patients (87.5%) had concurrent leg fractures. In 8 patients (57.1%), the bipedicled flap was used to decrease the wound size and facilitate another concurrent flap: hemisoleus (21.4%), anterior tibialis muscle turnover (14.3%), medial plantar artery (14.3%), and posterior tibial artery perforator (14.3%). Mean wound size for bipedicle flaps used alone was 42.0 ± 18.3 cm2, whereas wounds that required a bipedicled flap with an additional flap were 69.9 ± 80.8 cm2 (P = 0.187). Two patients had partial flap necrosis (14.3%) but healed their defect. One patient had nonunion (7.1%). Limb salvage rate was 100%. CONCLUSIONS: Bipedicled flaps can be used as an alternative to free flaps in distal third leg/foot defects in select patients. If distal extremity wounds cannot be covered with a bipedicled flap alone, the flap can be used an accessory flap to facilitate reconstruction with other local flaps.

Fundamentals of Microsurgery: A Novel Simulation Curriculum Based on Validated Laparoscopic Education Approaches.

BACKGROUND: Microsurgical techniques have a steep learning curve. We adapted validated surgical approaches to develop a novel, competency-based microsurgical simulation curriculum called Fundamentals of Microsurgery (FMS). The purpose of this study is to present our experience with FMS and quantify the effect of the curriculum on resident performance in the operating room. METHODS: Trainees underwent the FMS curriculum requiring task progression: (1) rubber band transfer, (2) coupler tine grasping, (3) glove laceration repair, (4) synthetic vessel anastomosis, and (5) vessel anastomosis in a deep cavity. Resident anastomoses were also evaluated in the operative room with the Stanford Microsurgery and Resident Training (SMaRT) tool to evaluate technical performance. The National Aeronautics and Space Administration Task Load Index (NASA-TLX) and Short-Form Spielberger State-Trait Anxiety Inventory (STAI-6) quantified learner anxiety and workload. RESULTS: A total of 62 anastomoses were performed by residents in the operating room during patient care. Higher FMS task completion showed an increased mean SMaRT score (p = 0.05), and a lower mean STAI-6 score (performance anxiety) (p = 0.03). Regression analysis demonstrated residents with higher SMaRT score had lower NASA-TLX score (mental workload) (p < 0.01) and STAI-6 scores (p < 0.01). CONCLUSION: A novel microsurgical simulation program FMS was implemented. We found progression of trainees through the program translated to better technique (higher SMaRT scores) in the operating room and lower performance anxiety on STAI-6 surveys. This suggests that the FMS curriculum improves proficiency in basic microsurgical skills, reduces trainee mental workload, anxiety, and improves intraoperative clinical proficiency.

Outcomes analysis of microsurgical physiologic lymphatic procedures for the upper extremity from the United States National Surgical Quality Improvement Program.

INTRODUCTION: Physiologic microsurgical procedures to treat lymphedema include vascularized lymph node transfer (VLNT) and lymphovenous bypass (LVB). The purpose of this study was to assess 30-day outcomes of VLNT and LVB using the National Surgical Quality Improvement Program (NSQIP) database. METHODS: NSQIP was queried (2012-2018) for lymphatic procedures for upper extremity lymphedema after mastectomy. Prophylactic lymphatic procedures and those for lower extremity lymphedema were excluded. Outcomes were assessed for three groups: LVB, VLNT, and patients who had procedures simultaneously (VLNA+LVB). Primary outcomes measured were operative time, 30-day morbidities, and hospital length of stay. RESULTS: The study included 199 patients who had LVB (n = 43), VLNT (n = 145), or VLNT+LVB (n = 11). There was no difference in co-morbidities between the groups (p = 0.26). 30-day complication rates including unplanned reoperation (6.9% VLNT vs. 2.3% LVB) and readmission (0.69% VLNT vs. none in LVB) were not statistically significant (p = 0.54). Surgical site infection, wound complications, deep vein thromboembolism, and cardiac arrest was also similar among the three groups. Postoperative length of stay for VLNT (2.5 days± 2.3), LVB (1.9 days± 1.9), and VLNT+LVB (2.8 days± 0.3) did not differ significantly (p = 0.20). Operative time for LVB (305.4 min ± 186.7), VLNT (254 min ± 164.4), and VLNT+LVB (295.3 min ± 43.2) was not significantly different (p = 0.21). CONCLUSIONS: Our analysis of the NSQIP data revealed that VLNT and LVB are procedures with no significant difference in perioperative morbidity. Our results support that choice of VLNT versus LVB can be justifiably made per the surgeon's preference and experience as the operations have similar complication rates.

Advantages of the Delayed-Immediate Microsurgical Breast Reconstruction: Extending the Choice.

BACKGROUND: Deep inferior epigastric perforator (DIEP) reconstruction can be performed in an immediate (at time of mastectomy), delayed-immediate (immediate tissue expander followed by staged DIEP), or delayed timing following mastectomy. Avoiding flap radiation is a known benefit of the delayed-immediate approach. The purpose of this study is to evaluate patients who chose DIEP flap as the reconstructive method during initial consultation and compared characteristics of surgery in relation to their final reconstructive choice. METHODS: Consecutive patients having breast reconstruction from 2017 to 2019 were divided into three groups: immediate DIEP after mastectomy (Group I); delayed-immediate DIEP with tissue expander first followed by DIEP (Group II); and patients who initially chose delayed-immediate DIEP but later decided on implants for the second stage of reconstruction (Group III). Exclusion criteria were patients that had delayed DIEP (no immediate reconstruction) or had initially chose implant-based reconstruction. RESULTS: The study included 59 patients. Unilateral free flaps in Group II had shorter operative times (318 minutes) compared with Group I unilateral free flaps (488 minutes) (p = 0.024). Eleven patients (30.6%) had prophylactic mastectomies in Group I compared with none in Group II (p = 0.004). Patients who had immediate tissue expansion frequently changed their mind from DIEP to implant for second stage reconstruction frequently (52.2%). CONCLUSION: Delayed-immediate DIEP reconstruction has several advantages over immediate DIEP flap including shorter free flap operative times. Patients commonly alter their preference for second stage reconstruction. A patient-centered advantage of delayed-immediate reconstruction is prolonging the time for patients to make their choice for the final reconstruction.

Do Patient Expectations of Discharge Affect Length of Stay after Deep Inferior Epigastric Perforator Flap for Breast Reconstruction?

BACKGROUND: Deep inferior epigastric artery perforator (DIEP) flap is a common method of breast reconstruction. Enhanced recovery after surgery (ERAS) postoperative protocols have been used to optimize patient outcomes and facilitate shorter hospital stays. The effect of patient expectations on length of stay (LOS) after DIEP has not been evaluated. The purpose of this study was to investigate whether patient expectations affect LOS. METHODS: A retrospective chart review was performed for patients undergoing DIEP flaps for breast reconstruction from 2017 to 2020. All patients were managed with the same ERAS protocol. Patients were divided in Group I (early expectations) and Group II (standard expectations). Group I patients had expectations set for discharge postoperative day (POD) 2 for unilateral DIEP and POD 3 for bilateral DIEP. Group II patients were given expectations for POD 3 to 4 for unilateral DIEP and POD 4 to 5 for bilateral. The primary outcome variable was LOS. RESULTS: The study included 215 DIEP flaps (45 unilateral and 85 bilateral). The average age was 49.8 years old, and the average body mass index (BMI) was 31.4. Group I (early expectations) included 56 patients (24 unilateral DIEPs, 32 bilateral). Group II (standard expectations) had 74 patients (21 unilateral, 53 bilateral). LOS for unilateral DIEP was 2.9 days for Group I compared with 3.7 days for Group II (p = 0.004). Group I bilateral DIEP patients had LOS of 3.5 days compared with 3.9 days for Group II (p = 0.02). Immediate timing of DIEP (Group I 42.9 vs. Group II 52.7%) and BMI (Group I 32.1 vs. Group II 30.8) were similar (p = 0.25). CONCLUSION: Our study found significantly shorter hospital stay after DIEP flap for patients who expected an earlier discharge date despite similar patient characteristics and uniform ERAS protocol. Patient expectations should be considered during patient counseling and as a confounding variable when analyzing ERAS protocols.

Immediate Lymphatic Reconstruction after Axillary Lymphadenectomy: A Single-Institution Early Experience.

PURPOSE: Lymphedema is progressive arm swelling from lymphatic dysfunction which can occur in 30% patients undergoing axillary dissection/radiation for breast cancer. Immediate lymphatic reconstruction (ILR) is performed in an attempt decrease the risk of lymphedema in patients undergoing axillary lymph node dissection (ALND). The purpose of this study was to assess the efficacy of ILR in preventing lymphedema rates in ALND patients. METHODS: An institutional review board-approved retrospective review was performed of all patients who underwent ILR from 2017 to 2019. Patient demographics, comorbidities, operative and pathologic findings, number of LVAs, limb measurements, complications, and follow-up were recorded and analyzed. Student's sample t-test, Fisher's exact test, and ANOVA were used to analyze data; significance was set at p < 0.05. RESULTS: Thirty-three patients were included in this analysis. Three patients (9.1%) developed persistent lymphedema, and two patients (6.1%) developed transient arm edema that resolved with compression and massage therapy. A significant effect was found for body mass index and the number of lymph nodes taken on the development of lymphedema (p < 0.01). CONCLUSIONS: The rate of lymphedema in this series was 9.1%, which is an improvement from historical rates of lymphedema. Our findings support ILR as a technique that potentially decreases the incidence of lymphedema after axillary lymphadenectomy. Obesity and number of lymph nodes removed were significant predictive variables for the development of lymphedema following LVA.

The False Positive Rate of Transcutaneous Tissue Oximetry Alarms in Microvascular Breast Reconstruction Rises after 24 Hours.

BACKGROUND: Transcutaneous tissue oximetry is widely used as an adjunct for postoperative monitoring after microvascular breast reconstruction. Despite a high sensitivity at detecting vascular issues, alarms from probe malfunctions/errors can generate unnecessary nursing calls, concerns, and evaluations. The purpose of this study is to analyze the false positive rate of transcutaneous tissue oximetry monitoring over the postoperative period and assess changes in its utility over time. METHODS: Consecutive patients undergoing microvascular breast reconstruction at our institution with monitoring using transcutaneous tissue oximetry were assessed between 2017 and 2019. Variables of interest were transcutaneous tissue oximetry alarms, flap loss, re-exploration, and salvage rates. RESULTS: The study included 175 patients (286 flaps). The flap loss rate was 1.0% (3/286). Twelve patients (6.8%) required re-exploration, with 9 patients found to have actual flap compromise (all within 24 hours). The salvage rate was 67.0%. The 3 takebacks after 24 hours were for bleeding concerns rather than anastomotic problems. Within the initial 24-hour postoperative period, 43 tissue oximetry alarms triggered nursing calls; 7 alarms (16.2%) were confirmed to be for flap issues secondary to vascular compromise. After 24 hours, none of the 44 alarms were associated with flap compromise. The false positive rate within 24 hours was 83.7% (36/43) compared with 100% (44/44) after 24 hours (p = 0.01). CONCLUSION: The transcutaneous tissue oximetry false positive rate significantly rises after 24 hours. The benefit may not outweigh the concerns, labor, and effort that results from alarms after postoperative day 1. We recommend considering discontinuing this monitoring after 24 hours.

Perioperative Use of Antiestrogen Therapies in Breast Reconstruction: A Systematic Review and Treatment Recommendations.

BACKGROUND: Patients with hormone receptor-positive breast tumors receive hormonal therapy with either selective estrogen receptor modulators (SERMs) (eg, tamoxifen) or aromatase inhibitors (AIs) (eg, anastrozole) for 5 to 10 years. Patients are using these therapies frequently during breast reconstruction. Literature investigating the effects of hormonal modulators on breast reconstruction outcomes demonstrates conflicting results. We sought to perform a systematic evaluation to assess the effects of hormonal therapy on breast reconstruction outcomes and to guide perioperative management of antiestrogen therapies. METHODS: A MEDLINE, PubMed, and EBSCO Host search of articles regarding the effects of SERMs and AIs on breast reconstruction was performed. Outcomes evaluated included wound complications, total or partial flap loss, and thromboembolic events. Included studies were assigned Methodological Index for Nonrandomized Studies quality scores. RESULTS: A total of 2581 flaps were analyzed for complete loss: patients taking SERMs at the time of reconstruction had higher rates of flap loss compared with patients not taking hormone modulators (P < 0.001). Flap loss was not affected by concurrent AI use (P = 0.11). Both SERMs and AIs had an increased risk of donor site complications (P = 0.0021 and P < 0.0001, respectively). Neither hormone modulator had an effect on flap wound complications or venous thromboembolic event rates. CONCLUSIONS: Evidence indicates patients using SERMs at the time of operation are at an increased risk of flap loss and those taking either SERMs or AIs have higher rates of donor site complications. These findings support holding these medications for 1 to 2 half lives (tamoxifen, 14-28 days; AIs, 2-4 days) preoperatively.

Unique Complications of Venous Anastomotic Couplers: A Systematic Review of the Literature.

BACKGROUND: Anastomotic couplers expedite venous microvascular anastomoses and have been established as an equivalent alternative to hand-sewn anastomoses. However, complications unique to the coupler such as palpability and extrusion can occur. The purpose of this study was to perform a systematic review of the literature to assess complications distinct to the venous anastomotic coupler. METHODS: A Medline, PubMed, EBSCO host search of articles involving anastomotic venous couplers was performed. Studies involving arterial anastomotic couplers, end-to-side anastomoses, and reviews were excluded. Data points of interest were flap failure, venous thrombosis, hematoma, partial flap necrosis, infection, coupler extrusion, and coupler palpability. RESULTS: The search identified 165 articles; 41 of these met inclusion criteria. A total of 8,246 patients underwent 8,955 venous-coupled anastomoses. Combined reoperation rate was 3.3% and all-cause unsalvageable flap failure was 1.0%. Complications requiring reoperation included venous thrombosis (2.0%), hematoma (0.4%), partial flap necrosis (0.4%), and infection (0.3%). Eight patients had palpable couplers and 11 patients had extrusion of couplers (head/neck, hand, and feet) and required operative management. CONCLUSION: Venous couplers remain an equivalent alternative to conventional hand-sewn anastomosis. However, venous coupler extrusion and palpability in the late postoperative period is a complication unique to anastomotic couplers, particularly in radiated head and neck, feet and hand free flaps. Removing extruded venous couplers is safe after tissue integration 3 weeks postoperatively. Coupler palpability and extrusion should be integrated into preoperative patient counseling and assessed in follow-up examinations.

Preoperatively Identified Sarcopenia Leads to Increased Postoperative Complications, Hospital and ICU Length of Stay in Autologous Microsurgical Breast Reconstruction.

BACKGROUND: Sarcopenia is a condition characterized by the loss of skeletal muscle mass and strength. Recently, there has been a tremendous amount of research into the prognostic value of sarcopenia in surgical outcomes. The purpose of this study was to compare postoperative outcomes in free flap breast reconstruction in patients with and without sarcopenia. METHODS: One hundred three patients who underwent autologous breast reconstruction from 2013 to 2016 were studied. The cross-sectional area (CSA) of skeletal muscle was measured from preoperative computed tomography images at L3 using the National Institutes of Health ImageJ software. CSA was then normalized to patient stature by dividing CSA by height (cm2/m2). A previously published skeletal muscle index cutoff of 38.5 cm2/m2 was used to define sarcopenia. Intraoperative and postoperative surgical outcomes were recorded retrospectively. Outcomes were analyzed using multivariate, univariate, and regression statistics. RESULTS: Eight of the 103 (7.8%) patients were found to have sarcopenia. Sarcopenia was associated with a statistically significant increase in flap site delayed healing (37.5% vs. 20%, p = 0.046), take back to the operating room (25% vs. 11.6%, p = 0.05), intensive care unit length of stay (1.5 vs. 0.02 days, p < 0.0005), and hospital length of stay (8.38 vs. 5.49 days, p < 0.0005) when compared with patients without sarcopenia. There were no significant differences in flap loss, surgical site infection, hematoma, seroma, donor site delayed healing, intraoperative complications, and number of revision surgeries. CONCLUSION: Sarcopenia is significantly associated with increased complications in patients undergoing free flap breast reconstruction. Further investigation into the biochemical and physiologic changes associated with sarcopenia is needed.

Delayed Breast Reconstruction on Patients With Upper Extremity Lymphedema: A Systematic Review of the Literature and Pooled Analysis.

BACKGROUND: Breast cancer-related lymphedema (BCRL) is a debilitating condition with morbidity, hindered quality of life, and increased health-related costs. Experimental studies support the use of musculocutaneous flaps for managing animal models with lymphedema. Although vascularized lymph node transfer (VLNT) and lymphovenous anastomosis are used to surgically treat patients with lymphedema, it is not known whether musculocutaneous or adipocutaneous flaps (eg, delayed autologous breast reconstruction) are effective for treating refractory upper extremity BCRL. We conducted a systematic review and pooled analysis to assess the impact of delayed breast reconstruction on developed BCRL. METHODS: Following PRISMA guidelines, we systematically searched PubMed, Scopus, EMBASE, and Google Scholar databases for relevant studies published through November 11, 2016. We screened 934 unique articles. Of these, we conducted full-text and reference screening on 37 articles. We then performed a pooled and sensitivity analysis using random effects. RESULTS: Eight studies met our inclusion criteria. One study was a case report; 7 studies were case series with sample sizes ranging from 3 to 38 patients. According to our pooled analysis 58% of patients reported improvement after breast reconstruction with or without VLNT. Sensitivity analysis revealed that 84% (95% confidence interval, 0.74-0.95) of patients who underwent breast reconstruction and VLNT reported improvement, whereas only 22% (95% confidence interval, 0.12-0.32) of those who had breast reconstruction alone reported improvement. CONCLUSIONS: Our review summarizes the current evidence regarding the effect of delayed breast reconstruction on established lymphedema. The VLNT component of the autologous breast reconstruction procedures may be the largest contributing factor leading to lymphedema improvement.

Management of Rhinophyma: Outcomes Study of the Subunit Method.

BACKGROUND: Rhinophyma causes a nasal deformity and functional airway obstruction. Partial excision (eg, tangential) with secondary healing commonly removes hypertrophic soft tissues but does not improve nasal support. The subunit method for rhinophyma uses 6 nasal flaps to provide exposure for removal of rhinophymatous tissue and enhance structure. The purpose of this study was to evaluate outcomes of subunit method. METHODS: Medical records of patients with rhinophyma treated with the subunit method between 2013 and 2016 were analyzed. The technique comprises degloving the distal half of the nose by elevating 6 subunit-based flaps; debulking phymatous tissues to perichondrium; enhancing nasal support with sutures/cartilage grafts; trimming excess skin; and redraping the soft tissues. Patient age, gender, need for cartilage grafts or skin grafts, revisions, and follow-up were assessed. RESULTS: The study comprised 8 patients (6 male). Mean age was 63 years (range 34-72). All individuals had interdomal sutures for tip enhancement and 4 patients underwent cartilage grafts (alar batten) to correct external valve collapse. One patient had 2 subunits (alar) replaced with skin graft. Average follow-up was 1.6 years (range 0.2-3.7). Six patients underwent revisional procedures primarily to modify the scar between the dorsum and tip subunits. CONCLUSION: The subunit method addresses the 3 fundamental problems of the rhinophymatous nose: hypertrophic sebaceous tissues, excess skin, and destruction of support. Most patients may benefit from a minor revisional procedure to optimize the result. Individuals should be counseled that operation will likely require 2 stages.

Systematic Review of the Surgical Treatment of Extremity Lymphedema.

Background Although conservative management of lymphedema remains the first-line approach, surgery is effective in select patients. The purpose of this study was to review the literature and develop a treatment algorithm based on the highest quality lymphedema research. Methods A systematic literature review was performed to examine the surgical treatments for lymphedema. Studies were categorized into five groups describing excision, liposuction, lymphovenous anastomosis (LVA), vascularized lymph node transfer (VLNT), and combined/multiple approaches. Studies were scored for methodological quality using the methodological index for nonrandomized studies (MINORS) scoring system. Results A total of 69 articles met inclusion criteria and were assigned MINORS scores with a maximum score of 16 or 24 for noncomparative or comparative studies, respectively. The average MINORS scores using noncomparative criteria were 12.1 for excision, 13.2 for liposuction, 12.6 for LVA, 13.1 for VLNT, and 13.5 for combined/multiple approaches. Loss to follow-up was the most common cause of low scores. Thirty-nine studies scoring > 12/16 or > 19/24 were considered high quality. In studies measuring excess volume reduction, the mean reduction was 96.6% (95% confidence interval [CI]: 86.2-107%) for liposuction, 33.1% (95% CI: 14.4-51.9%) for LVA, and 26.4% (95% CI: - 7.98 to 60.8%) for VLNT. Included excision articles did not report excess volume reduction. Conclusion Although the overall quality of lymphedema literature is fair, the MINORS scoring system is an effective method to isolate high-quality studies. These studies were used to develop an evidence-based algorithm to guide clinical practice. Further studies with a particular focus on patient follow-up will improve the validity of lymphedema surgery research.

An Experimental Study of Particulate Bone Graft for Secondary Inlay Cranioplasty Over Scarred Dura.

BACKGROUND: Inlay cranioplasty in children is challenging because autologous bone is limited. Cranial particulate bone graft effectively closes defects when placed over normal dura. The purpose of this study was to determine if particulate bone graft will ossify when used for secondary cranioplasty over scarred dura. METHODS: A 17 × 17-mm critical-sized defect was made in the parietal bone of 16 rabbits. Four animals had no implant (group 1). Twelve animals had the defect remade 16 weeks postoperatively, which was managed in 2 ways: group 2 (no implant; n = 6) and group 4 (particulate bone graft; n = 6). Particulate graft was obtained using a brace and bit from the frontal bone. Computed tomography was used to determine the area of ossification and thickness of the healed graft. Eight animals previously managed with particulate bone graft over normal dura were used as an additional control (group 3). RESULTS: Critical-sized defects filled with particulate bone graft over scarred dura (group 4) exhibited superior healing of the area (83.8%; range, 73.0%-90.6%) compared to control defects over normal dura (group 1: 62.9%; range, 56.5%-73.4%) or scarred dura (group 2: 56.9%; range, 40.0%-68.3%) (P = 0.0004). Particulate bone on scarred dura exhibited less ossified area (P = 0.002), and thinner bone (0.95 mm, range, 0.71-1.32 mm) compared to defects in which graft was placed over normal dura (group 3: area, 99.2%; range, 96.8%-100%; thickness, 1.9 mm, range; 1.1-3.1 mm) (P = 0.04). CONCLUSIONS: Particulate bone graft ossifies inlay cranial defects over scarred dura although inferior to placement over normal dura. Clinically, particulate bone graft may be used for secondary inlay cranioplasty.

Craniofacial fracture patterns in all terrain vehicle injuries.

BACKGROUND: A multicenter, retrospective study was conducted to determine the frequency and distribution of craniofacial fractures sustained from all terrain vehicle (ATV) accidents. METHODS: Medical records of all patients presenting to 2 trauma centers with ATV-related craniofacial trauma from 2001 to 2013 were reviewed. Patient notes and radiographic images were analyzed for detailed craniofacial injury data. The identified fractures were classified as: frontal/skullbase, naso-orbital, maxilla/zygoma, and mandible. In addition, patient demographic information, length of stay, airway status, intensive care unit stay, Glasgow coma scale, use of safety equipment, associated traumatic brain injury, and surgical intervention were compiled. RESULTS: One hundred fifty-six patients with craniofacial fractures secondary to ATV accidents presented from 2001 to 2013. The incidence of craniofacial fractures found in patients with ATV injuries was 12.2%. Sixty-one patients (39.1%) suffered frontal/skullbase fractures, 98 (62.8%) naso-orbital fractures, 62 (39.7%) maxillary/zygoma fractures, and 35 (22.4%) mandibular fractures. Forty-one patients (26.3%) required surgical intervention to correct their craniofacial injuries. CONCLUSIONS: The most common craniofacial fractures experienced in ATV injuries are naso-orbital fractures. The correlation of nonuse of safety equipment and associated traumatic brain injuries displays the importance of using helmets when operating ATVs. Future studies can be conducted examining ATV-related upper extremity injuries, among others.

Congenital Melanocytic Nevus of the Nose Removed Using Dermabrasion, Hydroquinone, and Serial Excision.

We report a child with a congenital pigmented nevus of the nose involving the left ala, sidewall, soft triangle, and tip. Removal of the lesion was performed using dermabrasion, topical hydroquinone, and serial excision to optimize the aesthetic outcome. The patient was left with a linear scar and did not require reconstruction with a skin graft or flap.

Subcostal Skin Graft Donor Site for Autologous Ear Construction.

Autologous ear construction for microtia creates an auricle using a costal cartilage framework. To separate the construct from the mastoid, a skin graft is required to form a retroauricular sulcus. Skin graft donor sites that have been described include the inguinal area (split or full-thickness) or scalp (split-thickness). The purpose of this study is to report a novel skin graft donor site for ear construction. We harvest a full-thickness graft from the subcostal area based on the previous scar from the cartilage harvest. Unlike the inguinal donor site, this method does not place an additional scar on the child. In contrast to the scalp donor site, the technique is simpler and a full-thickness graft minimizes contraction of the retroauricular sulcus.
