Introduction: Ergonomics have significant implications for the surgical workforce that performs at the interface between human-operated equipment and patient anatomy to achieve clinical results. This systematic review evaluated the literature discussing ergonomics in plastic surgery to explore current knowledge, evaluate trends, and identify prime gaps for future study., Methods: A systematic search strategy was developed by a licensed librarian and plastic surgeon to query all manuscripts evaluating ergonomics in plastic and reconstructive surgery. Two independent reviewers screened abstracts, evaluated full texts, and extracted data., Results: Forty-six studies were ultimately included. The number of published studies increased significantly over time when evaluated by year (ρ = 0.660, p < 0.001), with 17 (36.9%) written since 2020. Studies more commonly discussed musculoskeletal pain/disorders (n = 23) compared to surgical instrumentation or technology (n = 18, p = 0.390), operative posture (n = 14, p = 0.041), surgical technique (n = 6, p = 0.002), peri-surgical practices (n = 5, p < 0.001), and surgeon physiology (n = 3, p < 0.001). Among the 19 studies, including interventions, approaches more frequently involved novel instrumentation or technology (n = 14, 73.4%) compared to peri-surgical practices (n = 3, 6.5%, p < 0.001) or operative posture (n = 2, 4.3%, p < 0.001)., Conclusions: Ergonomics in plastic surgery has gained significant interest over time, with recent years representing a large proportion of published literature. Although most studies discuss musculoskeletal pain, the proportion of studies addressing posture and surgical practices are comparatively underrepresented, suggesting an opportunity for future intervention., (Copyright © 2024 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Background: The purpose of this study was to determine what craniometric changes occur to both orbits of unicoronal craniosynostosis patients undergoing fronto-orbital advancement and remodeling, and which of these changes are associated with new onset of postoperative strabismus., Methods: A retrospective analysis was performed of the preoperative and postoperative orbits of 24 unicoronal craniosynostosis patients and the orbits of 24 control subjects, totaling 144 orbits. Eight parameters were evaluated using multivariate logistic regression analysis. One of the parameters was modified orbital index, an indicator of severity of harlequin deformity., Results: Significant differences in orbital dimensions and angles were present bilaterally in unicoronal craniosynostosis orbits when compared to controls. Fronto-orbital advancement and remodeling increased the ipsilateral unicoronal craniosynostosis orbital volume from 13,184 ± 2003 mm to 16,220 ± 2323 mm (p < 0.001). Ipsilateral horizontal cone angles were increased from 48 ± 5 degrees to 54 ± 7 degrees (p = 0.004). Ipsilateral vertical cone angles were decreased from 73 ± 8 degrees to 66 ± 10 degrees (p = 0.003). Ipsilateral modified orbital index improved from 0.83 ± 0.06 to 0.88 ± 0.06 (p = 0.003). Three of the 19 unicoronal craniosynostosis patients developed transient postoperative strabismus. Logistic regression analysis displayed a strong significant association between new-onset strabismus and a change in modified orbital index with a coefficient of 30.84 ± 14.51 (p < 0.05)., Conclusions: The orbital dysmorphology in unicoronal craniosynostosis is bilateral in nature, and it is not wholly treated with conventional fronto-orbital advancement and remodeling. The severity of ipsilateral orbital dysmorphology is correlated with the incidence of postoperative strabismus following conventional fronto-orbital advancement and remodeling. Future research is needed to develop strategies to mitigate the risk of development of strabismus in this group of patients., Clinical Question/level of Evidence: Risk, III.

Purpose: The aim of this study is to evaluate the effect of timing of surgery and spring characteristics on correction of scaphocephalic deformity in patients undergoing spring-mediated cranioplasty (SMC) for sagittal craniosynostosis., Methods: The authors conducted a review of patients with sagittal craniosynostosis who underwent SMC at a tertiary referral center between July 2011 and March 2017, with a primary outcome measure of head shape, both preoperatively and postoperatively, determined by cephalic index (CI). Patient demographics and operative details including timing of surgery and spring characteristics were collected. Differences in CI preoperation and postoperation were compared using Wilcoxon signed-rank test. Ordinary least-squares linear regression was used to assess the impact of timing, number of springs, maximum single spring force, and total spring force on postoperative change in CI., Results: Thirty-six subjects (12 males and 24 females) were included in the study. Mean age at spring placement was 3.9 months (range: 1.9-9.2) with a mean follow-up of 1.4 years (range: 0.3-5.2). The mean number of springs used was 3 (range: 2-4). The mean maximum single spring force was 9.9 Newtons (N) (range: 6.9-13.0) and the mean total spring force was 24.6 N (range: 12.7-37.0). Mean CI increased from 70 ± 0.9 preoperatively to 77 ± 1.0 postoperatively (P < 0.001). Age at spring placement was significantly associated with change in CI: for every month increase in age, the change in CI decreased by 1.3 (P = 0.03). The number of springs used, greatest single spring force, and total spring force did not correlate with changes in CI (P = 0.85, P = 0.42, and P = 0.84, respectively)., Conclusion: In SMC, earlier age at time of surgery appears to correlate with greater improvement in CI, at least in the short-term. While spring characteristics did not appear to affect head shape, it is possible that the authors were underpowered to detect a difference, and spring-related variables likely deserve additional study.

Background: The establishment of an effective clinical and academic culture within an institution is a multifactorial process. This process is cultivated by dynamic elements such as recruitment of an accomplished and diverse faculty, patient geographic outreach, clinical outcomes research, and fundamental support from all levels of an institution. This study reviews the academic evolution of a single academic plastic surgery practice, and summarizes a 10-year experience of microsurgical development, clinical outcomes, and academic productivity., Methods: A 10-year retrospective institutional review was performed from fiscal years 2006 to 2016. Microsurgical flap type and operative volume were measured across all microsurgery faculty and participating hospitals. Microvascular compromise and flap salvage rates were noted for the six highest volume surgeons. Univariate and multivariable predictors of flap salvage were determined., Results: The 5000th flap was performed in December of 2015 within this institutional study period. Looking at the six highest volume surgeons, free flaps were examined for microvascular compromise, with an institutional mean take-back rate of 1.53 percent and flap loss rate of 0.55 percent across all participating hospitals. Overall, 74.4 percent of cases were breast flaps, and the remaining cases were extremity and head and neck flaps., Conclusions: Focused faculty and trainee recruitment has resulted in an academically and clinically productive practice. Collaboration among faculty, staff, and residents contributes to continual learning, innovation, and quality patient care. This established framework, constructed based on experience, offers a workable and reproducible model for other academic plastic surgery institutions., Clinical Question/level of Evidence: Therapeutic, IV.

Background: The Whitaker classification is a simple and widely used system for describing aesthetic outcomes after craniosynostosis surgery. The purpose of this study is to evaluate its interrater reliability for patients who have undergone fronto-orbital surgery., Methods: A retrospective review of patients with craniosynostosis who underwent surgical intervention at a tertiary referral center was conducted. Inclusion criteria were as follows: single-suture craniosynostosis, surgical intervention before age 2 years, and photographs taken before revisions between 5 and 20 years of age. Thirteen craniofacial surgeons independently reviewed the subjects' photographs and assigned Whitaker classifications. Interrater reliability was assessed with the Cohen kappa statistic., Results: Twenty-nine subjects were included. Average ages at surgery and at the time of postoperative photography were 0.8 year and 12.8 years, respectively. The κ value for all 13 raters was 0.1567 (p < 0.0001), indicating "slight agreement." Pairwise comparisons demonstrated κ values ranging from 0.0384 to 0.5492. The average rating for the set of 29 photographs differed significantly across the 13 raters (p = 0.0020) and ranged from 1.79 ± 0.68 to 2.79 ± 0.77. Finally, we found that average Whitaker classification did not differ significantly between subjects who subsequently underwent cranioplasty and/or fronto-orbital advancement and those who did not (subsequent procedures, 2.45 ± 0.55; no subsequent procedures, 1.88 ± 0.78; p = 0.1087)., Conclusions: The Whitaker classification exhibits low interrater reliability and does not predict future treatment. It may benefit craniofacial surgeons to create new evaluation tools with greater precision, to improve the quality of patient care and craniofacial outcomes research.

Complex abdominal wall reconstruction (AWR) is commonly performed, but with a significant rate of surgical complications and hernia recurrence. The aim of this experiential review is to assess risk factors for hernia recurrence after complex AWR. A retrospective review of AWR patients from 2007-2012 was performed. Rates of hernia recurrence were assessed. Univariate analyses and subsequent multivariate logistic regression analysis was used to assess independent predictors of early hernia recurrence. One hundred and thirty-four consecutive cases of AWR were performed over a 5-year period. Hernia recurrence developed in 14 (10.4%) patients. Hernias derived from trauma (OR = 19.76, p = 0.011) and those who experienced postoperative wound infections (OR = 18.81, p = 0.004) were at increased risk for hernia recurrence. In conclusion, increased vigilance must be paid to patients presenting after trauma with massive loss of domain and those who experience postoperative infection, as these cohorts are at added risk for failed reconstruction.

Background: This study reports long-term aesthetic outcomes with fronto-orbital advancement and cranial vault remodeling in treating unicoronal synostosis over a 35-year period., Methods: Retrospective review was performed on patients with isolated unicoronal synostosis from 1977 to 2012. Demographic, preoperative phenotypic, and long-term aesthetic outcomes data were analyzed with chi-squared and Fisher's exact test for categorical data and Wilcoxon rank-sum and Kruskal-Wallis rank for continuous data., Results: A total of 238 patients were treated; 207 met inclusion criteria. None underwent secondary intervention for intracranial pressure. At definitive intervention, there 96 (55 percent) Whitaker class I patients, 11 (6 percent) class II, 62 (35 percent) class III, and six (3 percent) class IV. Nasal root deviation and occipital bossing each conferred an increased risk of Whitaker class III/IV [OR, 4.4 (1.4 to 13.9), p = 0.011; OR, 2.6 (1.0 to 6.8), p = 0.049]. Patients who underwent bilateral cranial vault remodeling with extended unilateral bandeau were less likely Whitaker class III/IV at latest follow-up compared with those undergoing strictly unilateral procedures [OR, 0.2 (0.1 to 0.7), p = 0.011]. Overcorrection resulted in decreased risk of temporal hollowing [OR, 0.3 (0.1 to 1.0), p = 0.05]. Patients with 5 years or more of follow-up were more likely to develop supraorbital retrusion [OR, 7.2 (2.2 to 23.4), p = 0.001] and temporal hollowing [OR, 3.7 (1.5 to 9.6), p = 0.006] and have Whitaker class III/IV outcomes [OR, 4.9 (1.8 to 12.8), p = 0.001]., Conclusion: Traditional fronto-orbital advancement and cranial vault remodeling appears to mitigate risk of intracranial pressure but may lead to aesthetic shortcomings as patients mature, namely fronto-orbital retrusion and temporal hollowing., Clinical Question/level of Evidence: Therapeutic, IV.

Background: Ventral hernias are a common, challenging, and expensive problem for both the general and reconstructive surgeons; therefore, the aim of this study is to critically assess perioperative factors related to cost in abdominal wall reconstructions (AWR)., Methods: A retrospective review of AWR patients from 2007 and 2012 was performed. Analysis of perioperative factors associated with total cost of reconstruction was performed. Linear regression analyses were used to assess independent predictors of total cost., Results: 134 consecutive AWR performed by a single surgeon over a 5-year period at an academic teaching center were included. The average total cost of AWR was $61,251 ± 55,624. Linear regression analysis demonstrated that diabetes (P = 0.026), increased American Society of Anesthesiologists score (P = 0.002), preoperative anemia (P = 0.001), and hernias derived from trauma (P = 0.015) were independently associated with added cost in AWR when controlling for confounding variables. In addition, patients requiring intra-abdominal procedures (P = 0.012) and those receiving an AWR using Acellular Dermal Matrix (P = 0.015) accrued significantly greater cost. Interestingly, preoperative placement of an epidural (P = 0.011) was independently associated with significant cost savings and reduced medical morbidity. Major surgical complications (P < 0.001) and length of stay (P < 0.001) were independently associated with increased cost following AWR., Conclusion: We present a critical assessment of cost in AWR at a major academic teaching hospital and quantify the impact of reconstruction in the setting of medical morbidities and reconstructive complexities. The data from this study can be used to adjust reimbursement schemes and to critically assess the cost-benefit of performing AWR.

Background: The authors evaluated the complications, revisions, and long-term aesthetic outcomes of patients with isolated metopic synostosis., Methods: A retrospective chart review was performed on consecutive metopic craniosynostosis patients treated from June of 1987 to June of 2012 at The Children's Hospital of Philadelphia. Patient demographics, operative details, and postoperative data were collected. Outcomes were reported as Whitaker classification and postoperative clinical characteristics assessed before additional interventions. Reoperation in patients with greater than 5 years of follow-up was noted. Appropriate statistical analyses were applied., Results: From 1987 to 2012, 178 patients underwent surgical correction of isolated metopic craniosynostosis, and 147 met inclusion criteria. Average age at surgery was 0.83 year (range, 0.3 to 4.7 years); average follow-up was 5.8 years (range, 1.0 to 17.8 years). There were 13 surgical complications (8.8 percent), three major (2.0 percent), and 10 minor (6.8 percent). At follow-up, 67 patients (56.8 percent) were classified as Whitaker class I, six (5.1 percent) as class II, 43 (36.4 percent) as class III, and two (1.7 percent) as class IV. Patients with greater than 5 years' follow-up (n = 57) were more likely to have temporal hollowing (OR, 2.9; 95 percent CI, 1.2 to 7.3; p = 0.021), lateral orbital retrusion (OR, 4.9; 95 percent CI, 1.9 to 12.7; p = 0.001), and Whitaker class III or IV classification (OR, 4.0; 95 percent CI, 1.5 to 10.6; p = 0.006) compared with those with less than 5 years' follow-up., Conclusion: This study reports low complication and reoperation rates in the treatment of isolated metopic craniosynostosis, but demonstrates a clear trend toward worsening aesthetic outcomes over time., Clinical Question/level of Evidence: Therapeutic, IV.

Background: Ventral hernias are a common, challenging, and expensive problem for general and reconstructive surgeons. The authors assessed the impact of epidurals on morbidity following abdominal wall reconstruction for hernia., Methods: A retrospective review of abdominal wall reconstruction patients operated on between 2007 and 2012 was performed with a specific focus on the use of epidurals. Bivariate and multivariate logistic regression analyses were used to assess independent predictors of morbidity. Subgroup analyses were also performed., Results: The study included 134 consecutive reconstructions performed by a single surgeon over a 5-year period at an academic teaching center. Patient groups were similar in terms of demographics, preoperative characteristics, hernia grade, and intraoperative characteristics. Epidural use was associated with a lower incidence of major surgical complications (19.7 percent versus 36.1 percent; p = 0.04) and medical complications (26.8 percent versus 54.1 percent; p = 0.001). A significant and independent reduction in medical morbidity (OR, 0.09; p ≤ 0.001) and unplanned reoperations (OR, 0.23; p = 0.052), was found with patients receiving epidurals. Furthermore, a notable trend toward reduced major surgical complications (OR, 0.45; p = 0.141) and cost savings (-$22,184; p = 0.01) was found in patients who received epidurals. Subgroup analysis did not demonstrate statistically significant reductions in major surgical morbidity in reconstruction either with (p = 0.13) or without (p = 0.07) concurrent intra abdominal procedures when epidurals were not or were used, respectively., Conclusions: Epidural use may be associated with reduced morbidity and cost savings in abdominal wall reconstruction. This effect appears to be related to reduced medical morbidity and shortened length of stay in patients undergoing more complex, concurrent intraabdominal hernia procedures., Clinical Question/level of Evidence: Risk, II.

Background: This study explored factors associated with readmission following plastic surgery using a prospective, validated, national database., Methods: Patients who underwent primary plastic surgery procedures (n = 10,669) were identified from the 2011 American College of Surgeons National Surgical Quality Improvement Program databases. Those who were readmitted were compared with those who were not. Preoperative patient comorbidities, laboratory values, and intraoperative details derived from the data set were analyzed, and multivariate regression analysis was used to identify predictors of readmission., Results: A total of 10,669 patients were included, with a 4.5 percent readmission rate. Their average age was 49.5 years, 32.2 percent were obese, 15.2 percent were smokers, and 81.7 percent were women. The most commonly performed procedures included elective/cosmetic breast (23.4 percent), implant breast reconstruction (16.5 percent), revision breast procedures (14.9 percent), hand operations (9.7 percent), and body contouring (5.9 percent). The wound complication rate was 4.6 percent and the medical complication rate was 4.9 percent. The overall incidence of any postoperative complication was 10.9 percent, of which 4.8 percent were defined as major surgical complications. Independent risk factors associated with readmission included procedure type (p = 0.029); obesity (p = 0.011); anemia (p = 0.003); and medical (p < 0.001), major surgical (p < 0.001), and wound (p < 0.001) complications., Conclusions: The most significant predictor of readmission was postoperative complications. Patients experiencing postoperative surgical complications were six times more likely to be readmitted. These findings can assist surgeons and health systems to better tailor preoperative risk counseling, resource allocation, and postoperative discharge services.
