Clinical Practice Patterns and Evidence-Based Medicine in Secondary Cleft Rhinoplasty: A 14-Year Review of Maintenance of Certification Tracer Data From the American Board of Plastic Surgery.

OBJECTIVE: To evaluate evolving practice patterns in secondary cleft rhinoplasty. DESIGN: Retrospective review of data submitted during Maintenance of Certification (MOC). SETTING: Evaluation of MOC data from the American Board of Plastic Surgery. PARTICIPANTS: Tracer data for secondary cleft rhinoplasty were reviewed from August 2006 through March 2020, and the data subdivided from 20062012 and 20132020 to evaluate changes in practice patterns. INTERVENTIONS: Practice patterns in tracer data were compared to those from evidence-based medicine (EBM) literature over this time period. MAIN OUTCOME MEASURES: Practice patterns were compared to EBM trends during the study period. RESULTS: A total of 90 cases of secondary cleft rhinoplasty were identified. The average age at operation was 13 years (range 4-77). Cumulative data demonstrated 61% to present with nasal airway obstruction and 21% to have undergone primary nasal correction at the time of cleft lip repair; 72% of patients experienced no complications, with the most common complications being asymmetry (10%) and vertical asymmetry of alar dome position (6%). Cartilage graft was used in 68% of cases, with 32% employing septal cartilage. Change in practice patterns between 2006 to 2012 and 2013 to 2020 demonstrated increase in dorsal nasal surgery (26% vs 43%, P = .034), use of osteotomies (14% vs 38%, P = .010), septal resection and/or straightening (26% vs 48%, P = .034), and turbinate reduction (8% vs 30%, P = .007). CONCLUSIONS: These tracer data provide long-term data by which to evaluate evolving practice patterns for secondary cleft rhinoplasty. When evaluated relative to EBM literature, future research to further improve outcomes can be better directed.

Practice Profile of Practicing Plastic Surgeons: A 20-year Review of Plastic Surgery Statistics.

Background: Evaluation of practice patterns by American Board of Plastic Surgery (ABPS) diplomates allows for a greater understanding as to how the field is progressing. Understanding evolving procedural trends can give insight into plastic surgeons' subspecialty focus and influence resident training to prepare them for future practice. Methods: American Society of Plastic Surgeons member only projections for aesthetic and reconstructive procedures were reviewed from 1999 to 2018 in 5-year increments to identify shifts in frequency between the beginning (1999-2003) and end (2014-2018) of the timeframe. Tracer utilization for all four ABPS modules were also examined between 2014 and 2018. Descriptive statistics were performed to identify significant changes (P < 0.05) in subspecialty focus and procedure trends. Results: Annual procedure incidence between 2014 and 2018 was compared with that between 1999 and 2003. The annual number of procedures more than doubled from 3,244,084 to 6,628,082. Among reconstructive procedures, there was a statistically significant increase in the number of breast reconstruction, breast implant removal, and maxillofacial surgery procedures, and a statistically significant decrease in the number of procedures focused on reconstruction of birth defects, burn injuries, and hand anomalies. In aesthetic surgery, significant increases were seen in the number of augmentation mammoplasty, abdominoplasty, and mastopexy procedures, with significant decreases in the number of blepharoplasty and rhinoplasty procedures. Conclusions: Understanding the changing practice patterns of ABPS diplomates is essential to define the direction that our specialty is taking over time, and to guide program directors in plastic surgery on areas of focus for appropriate training of plastic surgeons.

Lessons from American Board of Plastic Surgery Maintenance of Certification Tracer Data: A 16-Year Review of Clinical Practice Patterns and Evidence-Based Medicine in Cleft Palate Repair.

BACKGROUND: As a component of the Maintenance of Certification process from 2003 to 2019, the American Board of Plastic Surgery tracked 20 common plastic surgery operations. By evaluating the data collected over 16 years, the authors are able to examine the practice patterns of pediatric/craniofacial surgeons in the United States. METHODS: Cumulative tracer data for cleft palate repair was reviewed as of April of 2014 and September of 2019. Evidence-based medicine articles were reviewed. Results were tabulated in three categories: pearls, or topics that were covered in both the tracer data and evidence-based medicine articles; topics that were covered by evidence-based medicine articles but not collected in the tracer data; and topics that were covered in tracer data but not addressed in evidence-based medicine articles. RESULTS: Two thousand eight hundred fifty cases had been entered as of September of 2019. With respect to pearls, pushback, von Langenbeck, and Furlow repairs all declined in use, whereas intravelar veloplasty increased. For items not in the tracer, the quality of studies relating to analgesia is among the highest of all areas of study regarding cleft palate repair. In terms of variables collected by the tracer but not studied, in 2019, 41 percent of patients received more than 1 day of antibiotics. CONCLUSIONS: This article provides a review of cleft palate tracer data and summarizes the research in the field. Review of the tracer data enables cleft surgeons to compare their outcomes to national norms and provides an opportunity for them to consider modifications that may enhance their practice.

Performance on the Plastic Surgery In-Service Examination Can Predict Success on the American Board of Plastic Surgery Written Examination.

BACKGROUND: Originally developed for resident self-assessment, the Plastic Surgery In-Service Examination has been administered for over 45 years. The Accreditation Council for Graduate Medical Education requires that at least 70 percent of graduates pass the American Board of Plastic Surgery Written Examination on their first attempt. This study evaluates the role of In-Service Exam scores in predicting Written Exam success. METHODS: In-Service Exam scores from 2009 to 2015 were collected from the National Board of Medical Examiners. Data included residency training track, training year, and examination year. Written Exam data were gathered from the American Board of Plastic Surgery. Multivariate analysis was performed and receiver operating characteristic curves were used to identify optimal In-Service Exam score cut-points for Written Exam success. RESULTS: Data from 1364 residents were included. Residents who failed the Written Exam had significantly lower In-Service Exam scores than those who passed (p < 0.001). Independent residents were 7.0 times more likely to fail compared with integrated/combined residents (p < 0.001). Residents who scored above the optimal cut-points were significantly more likely to pass the Written Exam. The optimal cut-point score for independent residents was the thirty-sixth percentile and the twenty-second percentile for integrated/combined residents. CONCLUSIONS: Plastic Surgery In-Service Exam scores can predict success on the American Board of Plastic Surgery Written Exam. Residents who score below the cut-points are at an increased risk of failing. These data can help identify residents at risk for early intervention.

Evolving Trends in Textured Implant Use for Cosmetic Augmentation in the United States.

BACKGROUND: Breast implants have evolved for decades. In 2011, the U.S. Food and Drug Administration identified an association between textured breast implants and breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). The purpose of this study was to identify the trends of textured implant use since that time. METHODS: Maintenance of Certification tracer data were queried between 2011 and 2015 for cosmetic breast augmentation cases submitted by American Board of Plastic Surgery diplomates. A nested random effects logistic regression analysis was used to identify associations between variables. RESULTS: Eleven thousand seven hundred sixteen breast augmentations were performed by 880 unique surgeons. The overall proportion of cases using textured implants increased steadily from 2.3 percent in 2011 to 13.0 percent in 2015 (p < 0.001). The proportion of surgeons whose cases included both textured and smooth implants increased (from 6.2 percent to 24.3 percent), as did those using only textured implants (from 0.4 percent to 4.4 percent) (p < 0.001). Significance remained after controlling for form-stable implants, suggesting an alternative motivation for use of textured implants. Subglandular cases (20.5 percent) were more likely to use a textured implant than submuscular (8.4 percent) or dual-plane (7.8 percent) (p < 0.001) cases. CONCLUSIONS: Maintenance of Certification tracer data represent a random sampling of American Board of Plastic Surgery-certified plastic surgeons spanning the gamut of practice settings. Despite ongoing education regarding the association of BIA-ALCL with textured implants, American Board of Plastic Surgery diplomates have trended toward increased use of textured implants for cosmetic breast augmentation since 2011. This finding does not appear to be driven by the introduction of anatomical implants during the study period.

Breast reconstruction following mastectomy.

There are numerous reconstructive options for patients undergoing mastectomy for breast cancer. These include autologous tissue transfer and implant reconstruction. Various factors play a role in determining the appropriate reconstructive course including the type of cancer resection and patient characteristics including comorbidities, smoking, body habitus, and patient preference. Patient education is an important component to minimizing the psychological trauma and emotional stress that accompanies treatment for breast cancer. All patients with breast cancer should be aware of their reconstructive options.

Uneventful versus Successful Reconstruction and Outcome Pathways in Implant-Based Breast Reconstruction with Acellular Dermal Matrices.

BACKGROUND: Meaningful data to help guide resource allocation for staged tissue expander/implant-based breast reconstruction are currently lacking. The authors seek to differentiate uneventful from successful reconstruction and identify common outcome pathways and factors that portend a deviation from an uneventful, two-stage, two-operation course. METHODS: A retrospective analysis of expander/implant reconstructions with or without acellular dermal matrix (2003 to 2009) was performed. Related postreconstructive events (including mastectomy flap necrosis, seroma, wound dehiscence, cellulitis, explantation, hematoma, and capsular revisions) were assessed for 2 years. Uneventful reconstruction was defined as exchange to breast implant within 2 years of tissue expander placement without complications, whereas successful reconstruction was defined as exchange to breast implant within 2 years with or without complications. Factors affecting reconstructive success were analyzed, and patterns of postreconstructive events were summarized as outcome pathways. RESULTS: Four hundred thirteen patients (295 with acellular dermal matrix and 118 without), with 602 breasts (432 with acellular dermal matrix and 170 without) underwent reconstruction. Forty-six percent of patients (48 percent with acellular dermal matrix and 40 percent without), experienced uneventful reconstruction. Reconstructive success was achieved in 337 patients (82 percent; 82.0 percent with acellular dermal matrix and 80.5 percent without), with reconstructive failure occurring in 58 patients. Multiple logistic regression analyses determined that cellulitis, seroma, and skin necrosis (OR, 15.8, 7.7, and 8.4, respectively) were highly predictive of reconstructive failure. The authors identified 10 distinct pathways experienced by tissue expander/implant patients that were characterized by specific postreconstructive events. CONCLUSION: The present study will facilitate discussions among patients, providers, and payers by providing a framework for understanding the myriad outcome pathways in implant-based reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Hospital-associated costs due to surgical site infection after breast surgery.

OBJECTIVE: To determine the attributable costs associated with surgical site infection (SSI) following breast surgery. DESIGN AND SETTING: Cost analysis of a retrospective cohort in a tertiary care university hospital. PATIENTS: All persons who underwent breast surgery other than breast-conserving surgery from July 1, 1999, through June 30, 2002. MAIN OUTCOME MEASURES: Surgical site infection and hospital costs. Costs included all those incurred in the original surgical admission and any readmission(s) within 1 year of surgery, inflation adjusted to US dollars in 2004. RESULTS: Surgical site infection was identified in 50 women during the original surgical admission or at readmission to the hospital within 1 year of surgery (N = 949). The incidence of SSI was 12.4% following mastectomy with immediate implant reconstruction, 6.2% following mastectomy with immediate reconstruction using a transverse rectus abdominis myocutaneous flap, 4.4% following mastectomy only, and 1.1% following breast reduction surgery. Of the SSI cases, 96.0% were identified at readmission to the hospital. Patients with SSI had crude median costs of $16 882 compared with $6123 for uninfected patients. After adjusting for the type of surgical procedure(s), breast cancer stage, and other variables associated with significantly increased costs using feasible generalized least squares, the attributable cost of SSI after breast surgery was $4091 (95% confidence interval, $2839-$5533). CONCLUSIONS: Surgical site infection after breast cancer surgical procedures was more common than expected for clean surgery and more common than SSI after non-cancer-related breast surgical procedures. Knowledge of the attributable costs of SSI in this patient population can be used to justify infection control interventions to reduce the risk of infection.

Risk factors for surgical site infection after major breast operation.

BACKGROUND: Understanding surgical site infection (SSI) risk factors after breast operation is essential to develop infection-prevention strategies and improve surgical outcomes. METHODS: We performed a retrospective case-control study with subjects selected from a cohort of mastectomy, breast reconstruction, and reduction surgical patients between January 1998 and June 2002 at a university-affiliated hospital. SSI cases within 1 year after operation were identified using ICD-9-CM diagnosis codes for wound infection and complication or positive wound cultures, or both. Medical records of 57 patients with breast SSI and 268 randomly selected uninfected control patients were reviewed. Multivariate logistic regression was used to identify independent risk factors for SSI. RESULTS: Significant independent risk factors for breast incisional SSI included insertion of a breast implant or tissue expander (odds ratio [OR] = 5.3; 95% CI, 2.5 to 11.1), suboptimal prophylactic antibiotic dosing (OR = 5.1; 95% CI, 2.5 to 10.2), transfusion (OR = 3.4; 95% CI, 1.3 to 9.0), mastectomy (OR = 3.3; 95% CI, 1.4 to 7.7), previous chest irradiation (OR = 2.8; 95% CI, 1.2 to 6.5), and current or recent smoking (OR = 2.1; 95% CI, 0.9 to 4.9). Local infiltration of an anesthetic agent was associated with substantially reduced odds of SSI (OR = 0.4; 95% CI, 0.1 to 0.9). CONCLUSIONS: Suboptimal prophylactic antibiotic dosing is a potentially modifiable risk factor for SSI after breast operation. SSI risk was increased in patients undergoing mastectomy and in patients who had an implant or tissue expander placed during operation. This information can be used to develop a specific risk stratification index to predict SSI and infection-preventive strategies tailored for breast surgery patients.

Effects of irradiation on nerve graft vasculature.

Increasing doses of therapeutic irradiation are known to impair nerve regeneration after grafting. One possible factor is the effect of irradiation on the endoneurial vasculature. This study investigates the effects of postoperative irradiation on the size, number, and cross-sectional area of endoneurial vessels in the rat posterior tibial nerve graft model. Sixty-five Sprague-Dawley rats underwent 1.5-cm interposition grafts to the tibial nerve. Postoperatively, they were assigned to one of five groups. The animals in Group 1 were unirradiated controls. Groups 2 to 5 received postoperative irradiation in the amounts of 46, 66, 86, and 106 Gy, respectively. One hundred and twenty days after grafting, sections of the proximal, grafted, and distal nerve were harvested and analyzed with digital morphometry. Statistical analysis of the average vessel area, number of vessels, and total vascular area was performed. The grafted segments of Groups 4 and 5 and the distal segments of all irradiated groups showed a statistically significant decrease in the number of vessels, compared to controls. The average size of the vessel was smaller in the proximal segment of the irradiated groups, compared to controls. There was no difference in size in either the grafted or distal segments of the irradiated groups, compared to controls. The observed changes in the endoneurial vasculature resulted from both the action of regeneration and the effects of irradiation. The irradiation effects appear to be dose-dependent.

A subjective rating scale for evaluating the appearance outcome of autologous breast reconstruction.

BACKGROUND: Subjective evaluations of the appearance outcome of autologous breast reconstruction are usually performed by surgeons and not by patients. Such surgeon-based evaluations are rarely reproducible and show little interobserver agreement. Among existing patient-based subjective scales, none has been tested for reliability, and no study to date has evaluated the reliability when both surgeons and patients use the same scale. METHODS: The authors developed a new instrument for assessing the appearance of autologous breast reconstruction. The instrument's use by four plastic surgeons and 36 transverse rectus musculocutaneous flap patients was assessed for test-retest reliability, internal consistency, surgeon-patient and surgeon-surgeon interobserver agreement, and interitem correlation. RESULTS: The instrument demonstrated high overall internal consistency when used by patients (Cronbach alpha = 0.92). Test-retest reliability on each aesthetic subitem in the scale was higher among patients than among surgeons (weighted kappa range, 0.57 to 0.88 versus 0.25 to 0.66). Interrater agreement was poor among both patients and surgeons (weighted kappa, 0.0 to 0.39). Poor correlation was found between surgeons' evaluations of aesthetic subitems and patients' overall appearance and overall satisfaction scores. CONCLUSIONS: The instrument both demonstrates better internal consistency and is more reliable when used by patients to evaluate their own reconstructions. By contrast, the instrument's use by surgeons is not as internally consistent and reproducible. The poor interobserver agreement among surgeons and the weak correlation between surgeon and patient evaluations suggest that patient input regarding item-specific criteria should be included in evaluations of breast reconstructions.
