Preferred Nasolabial Angle in Rhinoplasty: A Cross-Sectional Analysis.

BACKGROUND: The perception of an ideal nose is influenced by a variety of factors, with demographic characteristics playing a significant role in what is considered an ideal nose. The nasolabial angle (NLA) is considered one of the defining features shaping the nose. OBJECTIVES: In this study we set out to capture the perception of the ideal nasolabial angle among Canadian, Saudi, Kuwaiti, and Lebanese populations. METHODS: An online questionnaire-based cross-sectional study was conducted to investigate the ideal nasolabial angle among Canadian, Saudi, Kuwaiti, and Lebanese populations (n = 197). Participants were patients attending outpatient clinics, plastic surgery residents, and medical students. The questionnaire included demographics and the perception of respondents of the ideal NLA for each gender: male (85°, 90°, 95°, 100°, 110°) and females (95°, 100°, 110°, 115°). RESULTS: The majority of respondents were female (81.2%), ages between 20 and 39 (84.3%). The mean and standard deviation of ideal NLA choices in both male and female models were 97.1 ± 6.39 and 109.5 ± 5.32, respectively. The ideal male NLA choices were found to correlate significantly with age (P = .044) and work status (P = .019). In choosing the ideal female NLA, age was a significant factor (P = .012). CONCLUSIONS: Identifying the ideal NLA is essential to establishing aesthetic goals for patient and surgeon alike. It is important to understand the effects of demographics on the choice of the ideal NLA, which ultimately influences the planning and outcome of the rhinoplasty procedure.

The Effect of Tranexamic Acid Administration During Liposuction on Bleeding Complications and Ecchymosis: A Systematic Review.

Liposuction is the most frequently performed cosmetic procedure. Tranexamic acid (TXA) has emerged as a promising blood loss reducing agent in plastic surgery, but its value in liposuction is still being studied. This systematic review investigates the safety and efficacy of TXA in reducing blood loss during liposuction procedures. A systematic review of PubMed (US National Library of Medicine, Bethesda, MD), MEDLINE (US National Library of Medicine), EMBASE (Elsevier, Amsterdam, the Netherlands), and Cochrane databases (Wiley, Hoboken, NJ) from inception to June 2023 was performed. The primary objective was to compare blood loss, hematoma rate, and ecchymosis from liposuction procedures in patients who received TXA versus those who did not. The secondary objective was to assess the incidence of TXA-related complications. A total of nine studies were included, published between 2018 and 2023 of which eight were prospective and one was retrospective. A total of 345 intervention versus 268 control arms were compared. Follow-up time ranged from 1-14 days. Mean age, and mean BMI ranged from 33 - 50 years, 23 to 30 kg/m2, respectively. Blood loss in aspirate was significantly less with TXA administration assessed by five studies (p < 0.05). Of the five studies that assessed the incidence of ecchymosis, all reported less bruising with TXA use. Among all the studies, only one found post-operative complications with five patients requiring transfusion in the control group (without TXA). The evidence provided in the literature suggests that TXA use in liposuction is safe and effective for reducing blood loss and ecchymosis with IV and local administration.

Aesthetic Surgery Before-and-After Photography Bias on Instagram.

PURPOSE: This study aims to systematically assess body and facial aesthetic surgery before-and-after photography bias on Instagram. METHODS: An Instagram search using the term "plastic surgeon" was conducted on October 2020. The top 11 plastic surgeons' accounts were selected, and the first 15 images were selected from these profiles pertaining to different anatomical locations. Each photo was analyzed by a blinded board-certified plastic surgeon utilizing a 5-domain clinical photography bias score. The domains covered: (1) photo quality; (2) photo background; (3) position; (4) exposure/coverage; (5) bias. RESULTS: The search strategy identified a total of 161 sets of before and after. The most common anatomical site posted was the nose (n=47), followed by breasts (n=37). The most common angles posted were anterior-posterior view (n=61). The majority of images showed bias toward the post-operative image (70.8%). The main culprit with photo characteristics occurred due to there being a different post-operative background which was more flattering for the post-operative result (n=46, p=0.006) and a different view or angle, which again, flattered the post-operative image (n=36, p=0.02). Other factors that influenced the post-operative bias included photos of the patient covered with clothing (n=15, p=0.014) or standing (n=20, p=0.001), compared to a supine pre-operative image. CONCLUSION: Before-and-after photography conditions in aesthetic surgery is biased toward the post-operative result on Instagram. This observation was noticed across all surgical anatomical areas. Accounts photographer tends to misrepresent the photo background, view of angle, patients pose or position, or covering certain body parts.

Outcomes of Free Muscle Flaps versus Free Fasciocutaneous Flaps for Lower Limb Reconstruction following Trauma: A Systematic Review and Meta-Analysis.

BACKGROUND: Free flap reconstruction of the lower limb following trauma often suffers higher complication rates than other areas of the body. The choice of muscle or fasciocutaneous free flap is an area of active debate. METHODS: A systematic review of EMBASE, MEDLINE, PubMed, and Cochrane Register from inception to April 1, 2022 was performed. Articles were assessed using the methodological index for non-randomized studies instrument. The primary outcome was to assess and compare the major surgical outcomes of partial or total flap failure, reoperation, and amputation rates. RESULTS: Seventeen studies were included. All studies were retrospective in nature, of level three evidence, and published between 1986 and 2021. The most common muscle and fasciocutaneous free flaps used were latissimus dorsi flap (38.1%) and anterolateral thigh (ALT) flap (64.8%), respectively. Meta-analysis found no significance difference in rates of total flap failure, takeback operations, or limb salvage, whereas partial flap failure rate was significantly lower for fasciocutaneous flaps. The majority of studies found no significant difference in complication rates, osteomyelitis, time to fracture union, or time to functional recovery. Most, 82.4% (14/17), of the included studies were of high methodological quality. CONCLUSION: The rate of total flap failure, reoperation, or limb salvage is not significantly different between muscle and fasciocutaneous free flaps after lower limb reconstruction following trauma. Partial flap failure rates appear to be lower with fasciocutaneous free flaps. Outcomes traditionally thought to be managed better with muscle free flaps, such as osteomyelitis and rates of fracture union, were comparable.

Autologous Versus Alloplastic Reconstruction for Patients with Obesity: A Systematic Review and Meta-analysis.

BACKGROUND: Autologous flaps may have superior outcomes when compared to implant breast reconstruction in patients with obesity. To date, no published review has illustrated the superiority of autologous to implant-based reconstruction in this study group in terms of aesthetics outcomes and surgical complications. METHODS: A systematic search was conducted on PubMed, Cochrane, Google Scholar, and Embase from inception to December 31, 2020. Studies comparing the outcomes (patient satisfaction and complications) of autologous versus implant-based reconstruction in patients with BMI > 30 were selected. RESULTS: The search yielded 1633 articles, of which 76 were assessed in full text. A total of 12 articles fit inclusion for qualitative review; of them, 7 were meta-analyzed. Autologous reconstruction had a lower incidence of infection (OR 0.74 [95% CI 0.59, 0.92]), hematoma/seroma formation (OR 0.34 [95% CI 0.23, 0.49]), and reconstructive failure (OR 0.47 [95% CI 0.36, 0.62]), but not skin necrosis (OR 0.95 [95% CI 0.73, 1.25]) or wound dehiscence (OR 1.03 [95% CI 0.72, 1.49]) when compared to implant-based reconstruction. Deep vein thrombosis (DVT) and pulmonary embolism occurred more frequently with autologous versus alloplastic reconstruction (OR 2.21 [95% CI 1.09, 4.49] for DVT and OR 2.49 [95% CI 1.13, 5.48] for PE). BREASTQ scores were higher for the autologous breast reconstruction when compared to implant-based group, but failed to reach significance (p value >0.05). CONCLUSION: The current evidence in the literature suggests that autologous breast reconstruction has lower surgical complication rate when compared to implant-based reconstruction at the expense of higher risk of thrombotic complications for patients with BMI > 30.

Body Contouring Surgery Improves Weight Loss after Bariatric Surgery: A Systematic Review and Meta-Analysis.

INTRODUCTION: Our main objective is to evaluate the effect of body contouring surgery (BCS) on the magnitude and durability of weight loss after bariatric surgery. METHODS: Medline, EMBASE, Cochrane, and Scopus search were conducted from the time of their inception to June 2020. We included comparative studies that assessed weight progression, in terms of Body Mass Index change (∆BMI), Total Body Weight Loss (TBWL%), and Excess Weight Loss (%EWL) for the post-bariatric patient population and the effect of BCS on weight progression. RESULTS: Eleven articles were included. The pooled sample size was 2307, of which 691 were cases who underwent BCS post-bariatric surgery, and 1616 were comparative controls. The mean follow-up time for cases and controls were 61.6 ± 23.8 months and 52.2 ± 23.8 months, respectively. Nine studies reported results of BMI changes, six provided %EWL, and five used %TBWL. Significant improvement in weight loss was observed in the BCS group when measured by either ∆BMI (3 kg/m2 points decrease, p 0.023), %TBWL (6% increase, P < 0.0001), or %EWL (14% increase, P < 0.0001). Sub-group analysis showed that increased follow-up time was associated with higher TBWL% (p 0.02). CONCLUSION: The evidence provided in this review strongly supports the added long-term benefits of body contouring surgery for selected patients after massive weight loss following bariatric surgery. Having a multidisciplinary team that involves a bariatric and a plastic surgeon as well as nutritionists and psychologists for the management of patients with obesity going through the bariatric pathway is recommended.

Assessing the Knowledge and Insight of Medical Students into the Field of Plastic Surgery: A Step Toward Creating Well-Rounded Healthcare Professionals.

Introduction Plastic and reconstructive surgery (PRS) is unique in its versatility; however, there seems to be a lack of familiarity with the breadth of the discipline among healthcare workers and medical students. Methods This is a questionnaire-based, cross-sectional study conducted between June and July 2021, targeting medical students at Kuwait University. The questionnaire examined three domains: demographics, perception, and knowledge of the scope of PRS. Results A total of 465 medical students completed the survey, with most (N=106, 22.8%) being in their final year (seventh year). The majority (N=414, 89%) of students had no previous clinical exposure to PRS. Among the several PRS disciplines, knowledge was highest in the aesthetic discipline (4.1/5). Awareness in the hand (0.82/5) and craniofacial (0.8/5) disciplines were the lowest. Students in their clinical years had a higher overall PRS score when compared to those in their pre-clinical years (10.9 versus 9.1, p<0.0001). Participants who believed that PRS is a rewarding specialty had higher overall scores compared with those who disagreed (10.3 versus 9.5, p=0.055). Participants who believed that PRS is synonymous with cosmetic surgery had a lower overall score (9.3 versus 10.4, p=0.008). Furthermore, participants who would consider a career in PRS had a better understanding of all aspects of the specialty as evidenced by higher overall scores. Conclusion Exposure to the field of PRS improves medical students' insight into the various disciplines of PRS and ultimately influences how the field is perceived. Efforts should be made toward promoting the exposure of medical students to PRS through clinical placements and/or didactic lectures.

Pain and Functional Outcomes following Targeted Muscle Reinnervation: A Systematic Review.

BACKGROUND: It is estimated that by 2050, a total of 3.6 million patients will be living with an amputation in the United States. The objective of this systematic review is to evaluate the effect of targeted muscle reinnervation (TMR) on pain and physical functioning in amputees. METHODS: A literature search was performed on PubMed, Embase, and MEDLINE up to November 28, 2021. Clinical studies assessing the outcomes of TMR (pain, prosthesis control, life quality, limb function, and disability) were included. RESULTS: Thirty-nine articles were included. The total number of patients who underwent TMR was 449, and 716 were controls. Mean follow-up was 25 months. A total of 309 (66%) lower-limb and 159 (34%) upper-limb amputations took place in the TMR group, the most common being below-knee amputations (39%). The control group included a total of 557 (84%) lower-limb and 108 (16%) upper-limb amputations; the greatest proportion being below-knee amputations in this group as well (54%). Trauma was the most common indication for amputation. Phantom limb pain scores were lower by 10.2 points for intensity ( P = 0.01), 4.67 points for behavior ( P = 0.01), and 8.9 points for interference ( P = 0.09). Similarly, residual limb pain measures were lower for cases for intensity, behavior, and interference, but they failed to reach significance. Neuroma symptoms occurred less frequently, and functional and prosthesis control outcomes improved following TMR. CONCLUSION: The literature evidence suggests that TMR is a promising therapy for improving pain, prosthesis use, and functional outcomes after limb amputation.

Outcomes of Immediate versus Delayed Autologous Reconstruction in the Setting of Post-Mastectomy Radiation Therapy: A Meta-analysis.

INTRODUCTION: Post-mastectomy autologous breast reconstruction can be immediate (IBR) or delayed (DBR). The safety of performing IBR and the impact of radiation on the newly reconstructed breast is not yet validated. METHODS: A Pubmed, EMBASE, and Google scholar search was conducted from inception to September 17th 2023. We included comparative studies that assessed complications or aesthetic outcomes of IBR versus DBR in the setting of post-mastectomy radiotherapy (PMRT). RESULTS: The search identified 2693 articles. Thirteen were eligible for inclusion. A total of 565 patients underwent IBR followed by radiotherapy while 699 had DBR. Mean follow-up time and age for both groups were comparable (p > 0.1). None of revision surgery, infection, total flap failure, seroma, hematoma, dehiscence, or delayed wound healing was significantly different across groups (p > 0.1). IBR was found to have a higher risk of flap fibrosis (OR 28.18 [5.15 - 154.12]; p = 0.0001, I 2 of 44%) and skin flap necrosis (OR 6.12 [2.71 - 13.82]; p < 0.0001, I 2 of 27%) but a lower risk of partial flap failure (OR 0.18 [0.06 - 0.58]; p 0.004, I 2 of 0%) when compared to DBR. Results of fat necrosis should be interpreted with caution. Patient-reported as well as objective aesthetic outcomes were mostly comparable between groups. CONCLUSION: IBR in the setting of PMRT is increasingly being performed and poses a specific set of challenges that surgeons usually consider. The choice between IBR or DBR in the setting of PMRT should be an individualized decision based on patient risk factors and desires. LEVEL OF EVIDENCE: III.
