Ergonomics in Craniofacial Surgery: Can We Do Better? A Quality Improvement Study.

OBJECTIVE: Many plastic surgeons experience musculoskeletal strain and injury from poor ergonomics during surgery. This is associated with reduced performance, shortened careers, and decreased quality of life. This study compared the ergonomics of the conventional operating table headrest and the Mayfield headrest in craniofacial surgery. METHODS: A prospective cohort study of patients undergoing craniofacial operations between November 20, 2022 and April 26, 2023, within a single craniofacial surgeon's practice. The authors obtained data on the total duration of the operation and Rapid Entire Body Assessment (REBA) scores for the primary surgeon and assistant. RESULTS: Four operations (mean: 147 ± 60.9 min) were included in the regular headrest group, and 8 in the Mayfield headrest group (mean: 61±53.4 min). Four hundred fifty-five regular headrest time points and 851 Mayfield time points were recorded. Eight hundred thirty-five regular headrest time points and 538 Mayfield time points were recorded. The mean REBA score for the regular headrest was 5.79 ± 1.9, which was higher than the Mayfield (5.01 ± 2.0; P < 0.0001). Subgroup analysis showed the mean REBA score for the primary surgeon (5.89 ± 2.0) was higher than the assist (5.48 ± 1.6) in the regular headrest group ( P < 0.0001), whereas the converse was true for the Mayfield headrest (primary surgeon: 4.67 ± 1.8, assist: 5.65 ± 2.15, P < 0.0001). CONCLUSIONS: Ergonomic scores were better using the Mayfield headrest than the regular headrest. The primary surgeon scored better with the Mayfield headrest, whereas the assists had better scores with the regular headrest.

Use of Arterial Grafts in Hypothenar Hammer Syndrome: Application of Perforator Flap Anatomy.

BACKGROUND: Hypothenar hammer syndrome (HHS) is traditionally treated with venous bypass grafting, but controversy has arisen as arterial grafts have become more available. METHODS: A retrospective review of all patients undergoing ulnar artery bypass grafting for HHS with an arterial graft from 2008 to 2017 was performed. We also review the literature for patency rates and discuss the scenarios that favor different graft choices. RESULTS: Six patients were included in our series. Five had primary surgery and 1 had revision surgery for HHS. Five arterial grafts were from the deep inferior epigastric artery and 1 was from the lateral circumflex femoral artery. The proximal anastomotic site was the ulnar artery for all: n = 6. The distal anastomosis site was the palmar arch and common digital artery (CDA) of the ring/small finger and CDA of the middle/ring finger: n = 3; the palmar arch and the CDA of the ring/small finger: n = 3. All patients were symptom-free at follow-up and had a patent ulnar artery on Allen's testing or angiogram. CONCLUSION: Patency rates of arterial grafts for HHS appear to be excellent and this small series and may offer an alternative to traditional venous grafts and end-to-end arterial anastomoses. We suggest using arterial perforator grafts from free flap donor sites. These have well-described anatomy, are easily harvested, and carry minimal donor site morbidity. Lateral circumflex femoral artery graft is favored in patients requiring a single distal anastomosis, who have a ventral hernia, or who are obese. Deep inferior epigastric artery graft is preferred when multiple distal targets or versatile configurations are needed, in thin patients, or in female patients.

HISTORIQUE: Le syndrome du marteau hypothénarien (SMH) est généralement traité par un pontage veineux par greffe, mais une controverse sévit depuis que les greffes artérielles sont plus accessibles. MÉTHODOLOGIE: Les chercheurs ont procédé à une analyse rétrospective de tous les patients qui avaient subi un pontage de l'artère ulnaire par greffe pour traiter un SMH entre 2008 et 2017. Ils ont également fouillé les publications pour déterminer le taux de perméabilité des greffons et tenir compte des scénarios qui favorisent divers types de greffes. RÉSULTATS: Six patients ont fait partie de la série. Cinq avaient subi une opération primaire et un, une reprise de l'opération pour traiter un SMH. Cinq greffes artérielles provenaient de l'artère épigastrique inférieure profonde (AÉIP) et une, de l'artère circonflexe latérale de la cuisse (ACLC). Dans tous les cas (n=6), l'artère ulnaire était le foyer anastomotique proximal. Le foyer anastomotique distal était l'arcade palmaire et l'artère digitale commune (ADC) de l'annulaire et de l'auriculaire et l'ADC du majeur et de l'annulaire (n=3) ou l'arcade palmaire et l'ADC de l'annulaire et de l'auriculaire (n=3). Tous les patients étaient asymptomatiques au suivi et avaient une artère ulnaire perméable au test d'Allen ou à l'angiogramme. CONCLUSION: Le taux de perméabilité des greffes artérielles pour traiter le SMH semble excellent. Cette petite série peut ouvrir la voie à une autre solution que les greffes veineuses classiques et les anastomoses artérielles de bout en bout. Les chercheurs proposent d'utiliser des greffes de l'artère du perforateur provenant de foyers de lambeau libre d'un donneur. Leur anatomie est bien établie, les lambeaux sont faciles à prélever et ils entraînent une morbidité minime au site du donneur. La greffe de l'ACLC est privilégiée chez les patients qui ont besoin d'une anastomose distale simple, qui ont une hernie ventrale ou qui sont obèses. La greffe de l'AÉIP est favorisée lorsque de multiples cibles distales ou que des configurations polyvalentes sont nécessaires, que les patients sont minces ou qu'il s'agit de femmes.

Intraoperative Autoderm Decontamination for Use in Immediate Single-stage Direct-to-implant Breast Reconstruction.

Acellular dermal matrix (ADM) in direct-to-implant breast cancer reconstruction is the standard of care due to superior cosmetic results and decreased capsular contracture, but can be cost prohibitive. Although more economical, using patient's own dermis ("Autoderm") instead of ADM has undescribed sterility. Sterility is essential, as bacterial contamination may cause infection and capsular contraction. This study aimed to determine the sterility and optimal decontamination protocol of Autoderm. METHODS: A prospective controlled study of 140 samples from 20 DIEP (deep inferior epigastric perforator) breast cancer reconstruction patients was performed. Seven de-epithelialized dermal samples (2 × 1 cm) per patient were collected from excess abdominal tissue (6 decontamination protocols and one control). Samples were submerged in povidone-iodine, chlorhexidine, or cefazolin/tobramycin/bacitracin for 15 minutes; half of the samples were agitated (150 rpm) for 15 minutes, and half were not. The control was normal saline without agitation. The solution was removed, and the tissue was sent for aerobic colony count cultures. Patient's demographic data and complications were also collected. RESULTS: Of 140 samples, 3 of 20 non-agitated povidone-iodine and 1 of 20 control samples had aerobic bacterial growth. All of the other 100 samples from 5 experimental groups (povidone-iodine + agitation, chlorhexidine ± agitation, and cefazolin/tobramycin/bacitracin ± agitation) had no aerobic bacterial growth. CONCLUSIONS: This study suggests povidone-iodine + agitation, chlorhexidine ± agitation, and cefazolin/tobramycin/bacitracin ± agitation are effective at sterilizing de-epithelialized dermis, whereas povidone-iodine without agitation and saline are ineffective. Autoderm with the appropriate decontamination protocol may be a potential sterile alternative to ADM.

Lidocaine With Epinephrine Versus Bupivacaine With Epinephrine as Local Anesthetic Agents in Wide-Awake Hand Surgery: A Pilot Outcome Study of Patient's Pain Perception.

Purpose: Wide-awake local anesthesia hand surgery has many advantages over other forms of anesthesia, including faster recovery, lower cost, and improved patient safety; however, few studies compare postoperative pain and analgesic consumption after long- and short-acting anesthetics. This is important because surgeons seek to minimize opioid consumption during the opioid epidemic. Methods: This was a double-blinded, prospective, randomized, parallel design pilot study. We randomized 61 patients to receive carpal tunnel surgery with a short-lasting regional anesthetic (lidocaine, 29 patients) or a long-lasting one (bupivacaine, 32 patients). Primary outcomes were pain levels over the first and second 24 hours. Secondary outcomes were postoperative consumption of acetaminophen and opioids over the first and second 12 hours after surgery. Results: Pain intensity and acetaminophen consumption were significantly less in the bupivacaine group over the first 24 and 12 hours after surgery, respectively. The bupivacaine group consumed less opioids in the first 12 hours and delayed consumption of the first medication after surgery, but these results were not statistically significant. There was no difference in pain intensity or analgesic consumption between 24 and 48 hours after surgery. Conclusions: The use of a long-term anesthetic (bupivacaine) over a short-term one (lidocaine) in awake carpal tunnel release surgery decreases postoperative pain over the initial 12 hours after surgery and delays the initiation of analgesic consumption; however, this difference is small. The amount of opioid consumption was not significantly different between groups, but both groups consumed less than 10% of the prescribed opioids. It is important to reevaluate the need for opioids in minor hand surgery and favor the use of alternatives such as nonsteroidal anti-inflammatory drugs and acetaminophen. Type of study/level of evidence: Therapeutic I.

Three-dimensional Printed Surgical Simulator for Kirschner Wire Placement in Hand Fractures.

Closed reduction and percutaneous pinning (CRPP) of hand fractures can be a deceptively challenging procedure that requires significant hands-on time to teach and learn. We created a realistic three-dimensional simulator that can be used for teaching junior residents the CRPP. Computer-aided design and computer-aided manufacturing (CAD/CAM) software was used to create a three-dimensional hand model incorporating several common hand fractures: Bennett's fracture, transverse fifth metacarpal neck, and transverse second proximal phalanx. Three-dimensional printing was used to create molds in which the bones and soft tissue were poured. A polyurethane foam was utilized for the bones with iron incorporated to render them radiopaque, whereas silicone of varying viscosities was used for the soft tissues. Five plastic surgery residents and 5 consultants evaluated the model. Individuals then completed an anonymous 12-question survey evaluating the model based on realism, educational utility, and overall usefulness. Survey responses obtained from both residents and consultants were strongly in favor of the simulator. Average realism was graded as 4.48/5 by residents and 4.68/5 by consultants. Average educational utility was graded as 5/5 by residents and 4.95/5 by consultants. Average overall usefulness was graded as 5/5 by both groups. We created an anatomically accurate and realistic simulator for CRPP of hand fractures that was low cost and easily reproducible. Initial feedback was encouraging in regard to realism, educational utility, and overall usefulness.

USE of arterialized saphenous vein venous flow-through flaps as a temporizing measure for hand salvage in contaminated wounds presenting with limb ischemia: A case series.

BACKGROUND: Vascular injuries resulting in limb ischemia are traditionally treated acutely with autologous or prosthetic bypass grafts. Traumatic contaminated injuries with soft tissue and vascular segmental loss are challenging as prosthetic bypasses are at risk of erosion, infection, and occlusion; and autologous bypasses are at risk of desiccation, blow-out, infection, and clotting. We propose a novel approach to these injuries by using arterialized saphenous vein venous flow-through free flaps (S-VFTF) as an autologous bypass, and present the results of its application in a series of cases. METHODS: Spanning 2008 to 2015, four patients presenting with large contaminated crush/avulsion wounds with vascular injury underwent hand revascularization with S-VFTF, allowing the contaminated wounds to be serially debrided. Definitive soft tissue reconstruction was performed once the wound was considered clean. The S-VFTF skin paddle was de-epithelialized and the soft tissue defect covered with a free latissimus dorsi flap or a rectus abdominis myocutaneous flap. RESULTS: All ischemic limbs were successfully reperfused and there were no take backs for perfusion issues. All S-VFTF remained patent at discharge and final follow-up. No partial or complete finger/hand amputations were required. All definitive coverage free flap survived with no complications. CONCLUSION: The two-stage reconstruction presented may help reconstructive and vascular surgeons consider alternatives to traditional vascular reconstruction methods. This technique avoids an exposed vascular graft in an extensively contaminated open wound. It allows the surgeon to perform thorough and sufficient debridement of the wound, preventing definitive reconstruction in a not yet declared zone of injury.

Radiation Therapy Versus No Radiation Therapy to the Neo-breast Following Skin-Sparing Mastectomy and Immediate Autologous Free Flap Reconstruction for Breast Cancer: Patient-Reported and Surgical Outcomes at 1 Year-A Mastectomy Reconstruction Outcomes Consortium (MROC) Substudy.

PURPOSE: To determine whether adjuvant radiation therapy (RT) is associated with adverse patient-reported outcomes and surgical complications 1 year after skin-sparing mastectomy and immediate autologous free flap reconstruction for breast cancer. METHODS AND MATERIALS: We compared 24 domains of patient-reported outcome measures 1 year after autologous reconstruction between patients who received adjuvant RT and those who did not. A total of 125 patients who underwent surgery between 2012 and 2015 at our institution were included from the Mastectomy Reconstruction Outcomes Consortium study database. Adjusted multivariate models were created incorporating RT technical data, age, cancer stage, estrogen receptor, chemotherapy, breast size, body mass index, and income to determine whether RT was associated with outcomes. RESULTS: At 1 year after surgery, European Organisation for Research and Treatment of Cancer (EORTC) Breast Cancer-Specific Quality of Life Questionnaire breast symptoms were significantly greater in 64 patients who received RT (8-point difference on 100-point ordinal scale, P<.0001) versus 61 who did not receive RT in univariate and multivariate models. EORTC arm symptoms (20-point difference on 100-point ordinal scale, P=.0200) differed on univariate analysis but not on multivariate analysis. All other outcomes-including Numerical Pain Rating Scale, BREAST-Q (Post-operative Reconstruction Module), Patient-Report Outcomes Measurement Information System Profile 29, McGill Pain Questionnaire-Short Form (MPQ-SF) score, Generalized Anxiety Disorder Scale, and Patient Health Questionnaire-were not statistically different between groups. Surgical complications were uncommon and did not differ by treatment. CONCLUSIONS: RT to the neo-breast compared with no RT following immediate autologous free flap reconstruction for breast cancer is well tolerated at 1 year following surgery despite patients undergoing RT also having a higher cancer stage and more intensive surgical and systemic treatment. Neo-breast symptoms are more common in patients receiving RT by the EORTC Breast Cancer-Specific Quality of Life Questionnaire but not by the BREAST-Q. Patient-reported results at 1 year after surgery suggest RT following immediate autologous free flap breast reconstruction is well tolerated.

Effect of Erythropoietin on Transfusion Requirements for Craniosynostosis Surgery in Children.

BACKGROUND: Pediatric craniosynostosis surgery is associated with significant blood loss often requiring allogenic blood transfusion (ABT). This study explores the clinical effectiveness of preoperative erythropoietin (EPO) administration in pediatric craniosynostosis surgery in reducing transfusion requirements. METHODS: A systematic review and meta-analysis of the literature was performed for studies published in English language between 1946 and 2015. Inclusion criteria included original studies in the pediatric population (0-8 years of age) involving preoperative use of EPO in craniofacial procedures with quantitative reporting of perioperative blood transfusion. Extracted data included demographics, hematocrit, hemoglobin, estimated blood loss, number of patients transfused, and amount of ABT. RESULTS: Four studies met the inclusion criteria with a total of 117 patients. Patients were divided into 2 groups: EPO versus control. No statistical differences were found in the demographics between the 2 groups. Mean preoperative hematocrit level was higher in the EPO group compared with control (43% vs 35%). The percentage of patients who required ABT and the volume of transfused blood were less in the EPO group (54% vs 98% and 84 vs 283 mL, respectively). Meta-analysis of 3 comparable studies showed a lower proportion of patients who needed blood transfusion in the EPO group. CONCLUSIONS: The present meta-analysis demonstrated that preoperative administration of EPO in pediatric craniosynostosis surgery decreased the proportion of patients requiring ABT. In addition, the volume of transfusion was reduced in patients who received EPO. Future randomized studies are needed to establish the cost-effectiveness of routine preoperative EPO administration in craniosynostosis surgery.
