ABSTRACT

BACKGROUND: Breast reconstruction is a lengthy, multi-stage process guided by patients. It is vital to understand how their goals vary over time in order to achieve optimal outcomes. OBJECTIVES: This study aimed to evaluate how breast reconstruction patients' priorities changed throughout the reconstructive process. METHODS: Fifty women who underwent immediate breast reconstruction completed a quality of life survey at their preoperative appointment, 3, 6, and 12 months after surgery, and then again 10 years later. Scores on the survey's subsections corresponded to different patient priorities: survival, restitution, symmetry, and enhancement. The relationship between time and survey-measured patient priorities was analyzed with mixed-effects regression models and Tukey's HSD tests were used to make pairwise comparisons between time points. RESULTS: Survival scores decreased between 3 and 12 months after surgery (p < 0.001) before returning to baseline at long-term follow-up. Restitution scores were lowered only at 12 months PO (T4 vs. T1, T2, and T3, p < 0.001; T4 vs. T5, p = 0.003). Symmetry scores increased from preop to 6 months post-operation (p < 0.001), and then fell back to baseline by month 12 (p < 0.001) and remained at that level at long-term follow-up. Enhancement scores increased from pre-op to 12 months after surgery (p < 0.001), before returning to baseline at 10 year follow-up (T1 vs. T5, p > 0.99; T4 vs T5, p < 0.001). Time had an overall significant effect on each subsection score (p < 0.001), but this relationship was restricted to certain time points. CONCLUSIONS: In the year following immediate breast reconstruction, patients' concern over their physical health decreases while they become increasingly focused on enhancing the appearance of their reconstructed breasts. However, by ten years after surgery, patients' priorities were virtually unchanged from their preoperative desires.

ABSTRACT

Background: Changes in surgical education have caused concern over residents' preparedness for independent practice. As the field of otolaryngology requires such a wide breadth of expertise, ill preparation becomes especially costly. This study explores how the presence and participation of a postgraduate year 3 (PGY3) otolaryngology resident in surgery impacts revision rates and operating time as gauges for the resident competency and indirect training costs. Methods: A retrospective chart analysis of patients who underwent cosmetic plastic surgery at sites for PGY3 otolaryngology residents' facial plastic surgery rotations was conducted. Residents performed one side of bilateral procedures (eg, blepharoplasties) and approximately 50% of midline procedures (eg, rhinoplasties). Chi-squared testing and odds/risk ratios were done to assess the effect of resident involvement on revision rates. Operating time was compared using t tests. Results: When a resident was involved in cosmetic surgery, the revision rate was 22.2% compared with 3.6% without. The likelihood of a future revision surgery was 7.57 times higher when a resident participated in the original operation. Resident involvement was not a statistically significant predictor of exceeding the allotted operating time. Conclusions: The revision rate of cosmetic surgery was much higher when a resident was involved. Otolaryngology residents would benefit from increased facial plastic and reconstructive surgery training. As a response to this analytical study, this clinical rotation was moved to be offered at a later stage of postgraduate surgical training to allow residents to gain more experience and be better set up for success in the rotation.

ABSTRACT

BACKGROUND: Since the early 2000s, acellular dermal matrix has been a popular adjunct to prepectoral breast reconstruction to enhance outcomes. OBJECTIVES: The aim of this study was to investigate the differences in the postoperative course of 2 standard acellular dermal matrix products, AlloDerm SELECT Ready To Use and DermACELL. METHODS: A prospective, patient-blind study of patients undergoing bilateral nipple and/or skin-sparing mastectomies with either tissue expander or silicone implant insertion between 2019 and 2022 were selected for this study. The study design used patients as their own controls between 2 products randomly assigned to the left or right breast. Outcomes between the products included average time for drain removal, infection rate, seroma rate, and incorporation rates. RESULTS: The prospective clinical data of 55 patients (110 breasts) were recorded for 90 days. There were no significant differences between drain removal time, average drain output, or seroma aspiration amount. A higher percentage of seromas was recorded in the breasts with AlloDerm (30.91%) compared with breasts containing DermACELL (14.55%, P < .05), and a statistically significant difference between the incorporation rates of AlloDerm (93.4%) and DermACELL (99.8%, P < .05) was observed. CONCLUSIONS: Irrespective of patient demographic disparities, both products had a 94.55% success rate for reconstruction outcomes. AlloDerm was determined to have a higher incidence of seromas as a postoperative complication and a trend to lower incorporation.

ABSTRACT

Background: There is a growing societal trend in plastic surgery patients of viewing their medical care as a commodity product rather than as a healthcare service. Our four-provider private plastic surgery practice noticed this phenomenon through our patients' trend of overusing the emergency after-hours service call line. To affect this behavior, we designed a study educating patients on the emergency service call line's purpose and how to handle nonurgent issues independently. Methods: After a 6-month preintervention phase to categorize after-hours emergency calls, We improved preoperative patient education and implemented in-office protocols for quicker provider responses. Postintervention data were collected for another 6 months and compared statistically with the preintervention data. Results: In the preinterventional period, we saw a total of 236 after-hours phone calls. The intervention led to a 22% significant reduction in total calls (P = 0.007). Calls were categorized as nonurgent, urgent, and emergent. While emergent calls remained unchanged (P = 0.56), nonurgent calls significantly decreased (P = 0.005). The most common nonurgent calls were regarding pain, routine postoperative concerns, and drain care, with the intervention resulting in a significant reduction of routine postoperative swelling/bruising/discomfort calls (P = 0.04) but not changing pain (P = 0.23) or drain-related calls (P = 0.78). Conclusions: We found that targeted preoperative patient education coupled with a real-time action board in the office, to ensure timely response to patient questions during office hours, can positively impact after-hours call use, and improve overall patient outcomes by catching urgent issues earlier.

ABSTRACT

This trial aimed to compare the efficacy of a multimodal analgesic regimen with gabapentin to a multimodal nonsteroidal anti-inflammatory drug (NSAID) regimen following cosmetic surgery. This was a prospective randomized study of 106 patients undergoing elective outpatient cosmetic surgery. Methods: Patients were randomly assigned to a multimodal regimen of postoperative acetaminophen, gabapentin, and oxycodone with an acetaminophen and gabapentin preload or postoperative ibuprofen and oxycodone-acetaminophen protocol without a preload. Data on compliance, number of narcotic pills consumed, duration of analgesic use, pain levels, patient satisfaction, time from incision close to postanesthesia care unit (PACU) admission, and incidence of bleeding-related complications were collected and analyzed. Results: Patients from both regimens reported equivalent postoperative pain control with the exception of pain in PACU. NSAID patients exhibited a 9.3% higher rate of compliance (P = 0.01), a 6.0% higher rate of satisfaction with pain control (P = 0.04), a 25.2% shorter interval between closure and PACU (=0.01), and an 8.2% lower rate of bleeding-related complications, all of which were statistically significant (P < 0.05). Conclusions: Both regimens are viable tools in combating opioid overprescription as they both effectively reduce postoperative pain. However, the NSAID protocol resulted in greater satisfaction related to pain management and was more cost-effective by reducing emergence time from anesthesia. As there were no hematomas associated with the use of NSAIDs and a significantly higher rate of compliance, the use of NSAIDs in enhanced recovery after surgery protocols is supported.

ABSTRACT

BACKGROUND: Prescription opioid misuse has been recognized as a national epidemic. The implications of this problem are especially important to consider, as postoperative opioid abuse can give rise to true addiction for surgical patients. The concept of enhanced recovery after surgery is increasingly used across various specialties to decrease the overabundance of postoperative opioid use. METHODS: This study prospectively examined 143 patients undergoing cosmetic elective surgery. Patients were randomized into one of two groups based on postoperative pain management regimen: multimodal (enhanced recovery after surgery) analgesia or traditional opioid analgesia. Data regarding postoperative pain scores, amount of postoperative opioids consumed, and duration of postoperative pain pill use were analyzed. RESULTS: Multimodal (enhanced recovery after surgery) regimen patients experienced a 13.0 percent reduction in their pain scores after admission to the postanesthesia care unit and a 34.2 percent reduction in pain score at discharge, compared with traditional opioid patients (p = 0.049 and p = 0.0036, respectively). Enhanced recovery after surgery patients experienced a 35 percent reduction in the number of pills taken in the postoperative period and an 18.4 percent reduction in the duration of consumption (p = 0.0007 and p = 0.0539, respectively). CONCLUSIONS: The results demonstrate that multimodal postoperative pain management is an important tool for decreasing the amount of opioids prescribed and needed in the postoperative period. The overprescribing of opioids after surgery is a precursor to abuse and the increase in the national opioid reservoir. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

ABSTRACT

As healthcare costs continue to rise at unsustainable rates (at an average rate of 5.5% a year), expenses without measurable outcomes need review.1 In reconstructive surgery, empiric change of instruments between oncologic and reconstructive segments of surgery is one such practice. Breast surgery for ductal carcinoma in situ (DCIS), prophylaxis, and partial extirpation has little possible increase in seeding or implantation risk based on the literature. With undue extrapolation from higher risk cancers (such as ovarian), preventative practices of changing out trays, re-gloving, re-gowning, re-preparing, and re-draping between phases persist in operating rooms across the country. From real case costs, the additional expense of 2 surgical setups in the United States is conservatively estimated at $1232 per case, or over $125 million per year for this theoretical risk. Using implantation risk for core breast biopsies as a denominator, this cost is $1.65-$5.8 million per potential recurrence. This is an unacceptably high cost for hypothetical recurrence risk reduction, especially one that does not impact survival outcomes.

ABSTRACT

With the growing opioid epidemic, plastic surgeons are being encouraged to transition away from reliance on postoperative opioids. However, many plastic surgeons hesitate to use nonopioid analgesics such as nonsteroidal antiinflammatory drugs and local anesthetic blocks because of concerns about their safety, particularly bleeding. The goal of this systematic review is to assess the validity of risks associated with nonopioid analgesic alternatives. A comprehensive literature search of the PubMed and MEDLINE databases was conducted regarding the safety of opioid alternatives in plastic surgery. Inclusion and exclusion criteria yielded 34 relevant articles. A systematic review was performed because of the variation between study indications, interventions, and complications. Thirty-four articles were reviewed that analyzed the safety of ibuprofen, ketorolac, celecoxib, intravenous acetaminophen, ketamine, gabapentin, liposomal bupivacaine, and local and continuous nerve blocks after plastic surgery procedures. There were no articles that showed statistically significant bleeding associated with ibuprofen, celecoxib, or ketorolac. Similarly, acetaminophen administered intravenously, ketamine, gabapentin, and liposomal bupivacaine did not have any significant increased risk of adverse events. Nerve and infusion blocks have a low risk of pneumothorax. Limitations of this study include small sample sizes, different dosing and control groups, and more than one medication being studied. Larger studies of nonopioid analgesics would therefore be valuable and may strengthen the conclusions of this review. As a preliminary investigation, this review showed that several opioid alternatives have a potential role in postoperative analgesia. Plastic surgeons have the responsibility to lead the reduction of postoperative opioid use by further developing multimodal analgesia.

ABSTRACT

BACKGROUND: In recent years, the practice of cosmetic surgery has expanded to include oral and maxillofacial surgeons. The groundwork for this scope-of-practice expansion was laid in part by the American Dental Association's definition change of the practice of dentistry. This change modified the scope of dentistry from the earlier "teeth and surrounding and supporting structures" to the maxillofacial area and beyond. A number of states adopted this new definition into legislation, giving practitioners the premise on which to perform cosmetic and other medical procedures on the face and potentially other parts of the body. This expansion has created legal and regulatory issues over scope and truth in advertising. The authors hypothesize that this is confused by a lack of federal guidelines and state-by-state variations in scope-of-practice laws for oral and maxillofacial surgeons. METHODS: This article provides a brief overview of the key legal issues and their impact on legislation in some of the battleground states. The authors review the national distribution of scope of practice for oral and maxillofacial surgeons. RESULTS: The most successful path to expanded scope for dentistry has been through control of certification and credentialing. This has marginalized medicine boards from contributory oversight, thus circumventing any arguments over practice parameters. The scope-of-practice dispute is further complicated by the existence of dual-degree oral and maxillofacial surgeons. CONCLUSIONS: With increasing demand for cosmetic surgical interventions, establishing scope-of-practice standards for single-degreed oral and maxillofacial surgeons is critically important. As physicians, the oral and maxillofacial surgery graduates of the dual M.D./D.D.S. degree programs have no such scope-of-practice restrictions. Furthermore, if plastic surgery is to effectively argue against expanded scope of practice for oral and maxillofacial surgeons, more objective data will be necessary.

ABSTRACT

BACKGROUND: Capsular contracture is 1 of the most common complications after breast implant surgery and is a major indication for reoperation. Capsular contracture is believed to be a multifactorial process that is affected by implant texture, incision type, and ultimately pocket contamination. This contamination causes a biofilm that leads to capsular contracture. The intraoperative use of a Keller funnel is a mechanical way to decrease the implant's contact with the skin and ducts, reducing bacterial contamination that can cause these biofilms. For this reason, periareolar breast augmentation has been less popular among surgeons. The purpose of this study was to examine if there was a significant difference between the rates of capsular contracture in patients having periareolar breast augmentations with the use of a Keller funnel for insertion and those having periareolar breast augmentations without Funnel use. METHODS: This level 3 retrospective study followed 2 groups of patients, the first having periareolar breast augmentations without the use of a funnel for insertion (group A; patients n = 15; implants n = 30) and the second having periareolar breast augmentations with the use of a funnel for insertion (group B; patients n = 151; implants n = 300). RESULTS: The rate of capsular contracture in group A was found to be 10% compared with a rate of capsular contracture of 1.3% for patients in group B, an 87% reduction (P = 0.0019). CONCLUSIONS: According to the results found in this study, the rate of capsular contracture in patients having periareolar breast augmentations after insertion with a Keller funnel was statistically significantly lower than the rate in patients having implants inserted without the assistance of a funnel, making the device useful in reducing the occurrence of postoperative capsular contracture.

ABSTRACT

Medical tourism, or traveling abroad to obtain medical services, has evolved into a global health care phenomenon, with over 15 million U.S. patients each year seeking medical care internationally, representing a $50 billion dollar industry in 2017. Speculation and media fascination about the growing industry, diverse destinations, and rationale behind the medical tourists is rampant; however, the legal implications of tourism medicine, particularly when it goes wrong, are often unclear. On the international stage, accreditation agencies are limited in scope and practice, legal jurisdiction is difficult to establish, and the enforcement of rulings is nearly impossible. Patients seeking tourism medicine have little legal recourse and shoulder all the legal burden.

ABSTRACT

BACKGROUND: Psychoactive drug use is on the rise in the United States, with plastic surgery patients a potentially susceptible group. This study aimed to determine the incidence of cosmetic and reconstructive patients in our practice taking psychoactive drugs and to compare those values with the national average. Furthermore, we discuss the patient safety concerns when patients withhold their medical history information over the course of their treatment. METHODS: Urban private plastic practice patients who underwent surgery in a closed practice from 2009 to 2016 were divided into cosmetic and reconstructive cohorts. Review for drug use was medical scripts, history, and Surescripts drug reporting. Extracted information includes age, race, procedure, psychoactive medications, and whether or not they stated a mental health diagnosis on their medical history forms. Only patients with complete records were included. RESULTS: A total of 830 patients were included in statistical analysis. Due to minimal cohort number, 70 men were excluded, as there were no comparative national data. Our analysis found that 33.6% cosmetic patients and 46.3% reconstructive patients used at least one psychoactive drug. CONCLUSION: There is a statistically significant difference between psychoactive drug use at our practice compared with the general population and a significantly larger percentage of reconstructive patients taking drugs compared with the cosmetic cohort.

ABSTRACT

BACKGROUND: A best practice goal to reduce surgical site infection includes administration of antibiotics in the ideal preoperative window. This article evaluates an office surgical suite antibiotic administration rate and compares it with the timing of a local hospital treating a similar patient population. The hypothesis was that similar or better compliance and surgical site infection rates can be achieved in the office-based suite. METHODS: A total of 277 office-based surgeries were analyzed for antibiotic administration time before incision and their corresponding surgical site infection rate. RESULTS: Our facility administered timely prophylactic antibiotics in 96% of cases with a surgical site infection rate of 0.36%. This rate was significantly lower than a reported rate of 3.7%. CONCLUSION: Low infection rates with high antibiotic administration rate suggest that compliance with best possible practice protocols is possible in the outpatient setting.

ABSTRACT

BACKGROUND: For the noncolonized wound, achieving tension-free, primary wound closure is ideal. Some surgeons advocate imbrication of deeper tissues rather than undermining, posing that imbrication preserves more dermal perfusion while still reducing tension at the wound edge. We sought to determine which technique most reliably reduced wound tension while preserving dermal wound perfusion. METHODS: A total of 5 standardized, symmetrical pairs of full thickness wounds were created on Duroc swine. Wound tension was measured with a Tyrolean tensiometer before and after either method of closure, whereas a speckle contrast imager was used to assess dermal edge perfusion. Skin tension and dermal perfusion were evaluated for statistical significance via paired t tests and a multivariate analysis of variance. RESULTS: There was a significant reduction in wound tension with undermining and imbrication relative to the raw wound tension (5 and 5.9 vs 7.1 N; P < 0.05) yet no significant difference between methods of closure (P > 0.05). There was a significant reduction in dermal perfusion between unwounded skin and the imbricated wound (222 perfusion units [PU] vs 48 PU; P < 0.05) and between the unwounded skin and the undermined wound (205 vs 63 PU; P < 0.05). CONCLUSIONS: We found no significant difference in wound tension between wound undermining or imbrication and a significant decrease in dermal perfusion after imbrication and undermining although the relative decrease in perfusion was greater with imbrication. Wound undermining reduces skin tension with greater relative dermal perfusion to the skin and should be selected over wound imbrication in standard primary wound closure.

ABSTRACT

INTRODUCTION: Operating costs are a significant part of delivering surgical care. Having a system to analyze these costs is imperative for decision making and efficiency. We present an analysis of surgical supply, labor and administrative costs, and remuneration of procedures as a means for a practice to analyze their cost effectiveness; this affects the quality of care based on the ability to provide services. The costs of surgical care cannot be estimated blindly as reconstructive and cosmetic procedures have different percentages of overhead. METHODS: A detailed financial analysis of office-based surgical suite costs for surgical procedures was determined based on company contract prices and average use of supplies. The average time spent on scheduling, prepping, and doing the surgery was factored using employee rates. RESULTS: The most expensive, minor procedure supplies are suture needles. The 4 most common procedures from the most expensive to the least are abdominoplasty, breast augmentation, facelift, and lipectomy. CONCLUSIONS: Reconstructive procedures require a greater portion of collection to cover costs. Without the adjustment of both patient and insurance remuneration in the practice, the ability to provide quality care will be increasingly difficult.

ABSTRACT

The prevalence of obesity over the last several decades in the United States has tripled among children and doubled among adults. Obesity increases the incidence and progression of multiple myeloma (MM), yet the molecular mechanisms by which adipocytes contribute to cancer development and patient prognosis have yet to be fully elucidated. Here, we obtained human adipose-derived stem cells (ASCs) from twenty-nine normal (BMI = 20-25 kg/m(2)), overweight (25-30 kg/m(2)), obese (30-35 kg/m(2)), or super obese (35-40 kg/m(2)) patients undergoing elective liposuction. Upon differentiation, adipocytes were co-cultured with RPMI-8226 and NCI-H929 MM cell lines. Adipocytes from overweight, obese and super obese patients displayed increased PPAR-gamma, cytochrome C, interleukin-6, and leptin protein levels, and decreased fatty acid synthase protein. 8226 MM cells proliferated faster and displayed increased pSTAT-3/STAT-3 signaling when cultured in adipocyte conditioned media. Further, adipocyte conditioned media from obese and super obese patients significantly increased MM cell adhesion, and conditioned media from overweight, obese and super obese patients enhanced tube formation and expression of matrix metalloproteinase-2. In summary, our data suggest that adipocytes in the MM microenvironment contribute to MM growth and progression and should be further evaluated as a possible therapeutic target.
