1. Tranexamic Acid for Postoperative Outcomes in Breast Plastic Surgery: A Systematic Review and Meta-analysis.
In a meta-analysis of 8 studies (n=2311), tranexamic acid significantly reduced hematoma formation after cosmetic and reconstructive breast surgery (OR 0.37) but did not significantly affect seroma, infection, or partial nipple-areolar complex loss. Findings support TXA as an adjunct to improve postoperative outcomes.
Impact: This synthesis provides Level I evidence that TXA lowers hematoma risk in aesthetic breast procedures, a common and costly complication, informing perioperative protocols.
Clinical Implications: Consider incorporating TXA into breast aesthetic and reconstructive surgical protocols to reduce hematoma risk, while individualizing use and monitoring pending dose/route optimization in future trials.
Key Findings
- TXA significantly reduced hematoma formation after breast plastic surgery (OR 0.37; 95% CI 0.24–0.58; p<0.0001).
- No significant reduction in seroma formation (OR 0.65; 95% CI 0.33–1.27; p=0.21).
- No significant effect on infection rates (OR 1.84; 95% CI 0.49–6.94; p=0.37).
- No significant effect on partial nipple-areolar complex loss (OR 0.47; 95% CI 0.12–1.82; p=0.28).
Methodological Strengths
- Comprehensive database search (PubMed, Embase, Cochrane CENTRAL) with predefined criteria
- Quality assessment via Newcastle–Ottawa Scale and random-effects pooling with ORs and 95% CIs
Limitations
- Heterogeneity in included study designs and TXA regimens cannot be fully resolved from the abstracted data.
- Non-significant effects on several secondary outcomes limit generalizability beyond hematoma reduction.
Future Directions: Prospective, adequately powered RCTs should define optimal TXA dosing, route (topical vs systemic), timing, and safety endpoints specific to aesthetic breast procedures.
BACKGROUND AND OBJECTIVES: Tranexamic acid (TXA), a synthetic antifibrinolytic agent, offers considerable promise as a potential therapy to improve postoperative outcomes for patients undergoing breast surgery. However, its specific role in plastic breast surgery remains understudied. Hence, we aimed to evaluate its efficacy in cosmetic plastic breast surgery. METHODS: An extensive literature search of electronic databases such as PubMed, Embase, and Cochrane CENTRAL was conducted from inception to October 2023. Quality assessment of the included studies was done using the Newcastle-Ottawa scale (NOS). The results of our analyses were presented as odds ratios (ORs) with 95% confidence intervals (CIs) and pooled using a random effects model. A p-value < 0.05 was considered significant in all cases. RESULTS: A total of 8 studies, encompassing 2311 participants were included in our analysis. The pooled analysis demonstrates that TXA is associated with a significant improvement in hematoma formation (OR 0.37, 95% CI: 0.24-0.58; p < 0.0001). There was no significant improvement in seroma formation (OR 0.65, 95% CI: 0.33-1.27; p = 0.21), infection rate (OR 1.84, 95% CI: 0.49-6.94; p = 0.37) or partial loss of the nipple-areolar complex (OR 0.47, 95% CI: 0.12-1.82; p = 0.28). CONCLUSION: Tranexamic acid demonstrated considerable efficacy in improving postoperative outcomes for patients undergoing cosmetic and reconstructive breast surgeries.

2. Three-Dimensional Computed Tomography Angiography for Safer Filler Injections in Lying Ear Corrections: Identifying Key Vascular Structures.
Cadaveric 3D-CTA mapping shows that the cephaloauricular sulcus is primarily supplied by the medial temporal, posterior auricular, and superior auricular arteries. Regions B and C1 appear hypovascular and relatively safer for filler injections, while A, C2, and D pose higher risk; measured distances from the PAA to the sulcus provide practical guidance.
Impact: Defines anatomical safe zones and high-risk regions for ear filler injections using quantitative 3D-CTA, directly informing complication avoidance.
Clinical Implications: Use regions B and C1 preferentially and avoid A, C2, and D when planning ear filler injections; integrate measured distances from the posterior auricular artery to guide cannula/needle placement.
Key Findings
- Primary arterial supply to the cephaloauricular sulcus arises from the medial temporal, posterior auricular, and superior auricular arteries.
- Hypovascular and relatively safer regions identified: B and C1; higher-risk regions: A, C2, and D.
- Distances from the posterior auricular artery to the cephaloauricular sulcus: 5.6±1.5 mm, 8.8±2.1 mm, 10.7±1.9 mm (region B points), and 10.1±2.2 mm (inferior point of C1).
Methodological Strengths
- High-resolution 3D-CTA with vessel segmentation using Mimics software
- Standardized anatomical coordinate system based on the Frankfurt plane to enable reproducible regional mapping
Limitations
- Cadaveric imaging without in vivo physiological validation limits direct clinical generalizability.
- Exact number of unique cadaver specimens and inter-individual variability are not detailed in the abstract.
Future Directions: Prospective clinical validation correlating these anatomical safe zones with complication rates in ear filler procedures; development of injection algorithms and training tools based on the 3D map.
BACKGROUND: Concerns exist regarding potential complications associated with injectable cosmetic treatments for lying ear correction. This study aimed to examine the blood vessel distribution patterns in the ear and face related to ear filler procedures and surgery by using 3-dimensional computed tomography angiography of cadaveric head specimens. METHODS: In total, 50 high-resolution images of the lateral aspects of the specimens were captured. The 3-dimensional images of blood vessels in the cephaloauricular sulcus were created using Mimics. The coordinate system was established on the basis of the highest points of the bilateral external auditory canals and the left suborbital border point, corresponding to the Frankfurt plane. The posterior cephaloauricular region was divided into regions A, B, C, and D, with region C further subdivided into regions C1 and C2. RESULTS: The primary blood supply to the cephaloauricular sulcus comes from the medial temporal artery, posterior auricular artery (PAA), and superior auricular artery. Two hypovascular regions, referred to as regions B and C1, were observed between the cephaloauricular sulcus and the PAA. The measured distances from the PAA to the cephaloauricular sulcus at 3 evenly spaced points in region B and at the inferior point of region C1 were 5.6 ± 1.5 mm, 8.8 ± 2.1 mm, 10.7 ± 1.9 mm, and 10.1 ± 2.2 mm, respectively. CONCLUSIONS: Regions A, C2, and D pose a higher risk for filler injections, whereas regions B and C1 are relatively safer. This study provides valuable insights into the safe administration of filler injections for correction of lying ears. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.
3. Evaluating the Effectiveness and Safety of Home Facial Antiaging Beauty Devices Based on Meridian and Acupoint Theory.
In a 4-week randomized controlled trial (n=90; 80 completers), two home facial devices based on meridian/acupoint theory significantly improved wrinkles, texture, radiance, and laxity versus control (p<0.05). No significant differences in physical health were observed; further safety validation is needed.
Impact: Provides randomized evidence addressing the efficacy of widely used home antiaging devices, informing dermatology and consumer guidance.
Clinical Implications: Clinicians can cautiously recommend select home devices for short-term improvement of skin aging parameters, while counseling on limited duration data and the need for safety monitoring.
Key Findings
- Randomized 4-week trial with 90 participants; 80 completed.
- Both device groups improved wrinkles, texture, radiance, and laxity versus control (p<0.05).
- No significant improvements in physical health outcomes (p>0.05).
- Authors note efficacy with a call for further safety verification and device usability optimization.
Methodological Strengths
- Randomized controlled design with a concurrent control group
- Objective imaging (VISIA) and standardized photography alongside QoL assessments
Limitations
- Short follow-up (4 weeks) with limited safety data.
- Device specifics and blinding procedures are not detailed in the abstract.
Future Directions: Longer, blinded RCTs across diverse populations to validate durability and safety; head-to-head comparisons and integration with standardized skincare regimens.
BACKGROUND: The increasing use of home beauty devices for antiaging raises questions about their efficacy and safety. Traditional Chinese medicine suggests that stimulating certain meridians and acupoints can aid in antiaging. This study evaluates the effects of two popular home facial devices on facial and body aging, integrating meridian and acupoint theory. METHODS: A randomized controlled trial with 90 volunteers (25-65 years) over 4 weeks assessed the devices' impact on skin aging and physical health. Participants were divided into three groups: Group Y, Group J, and a control group. Outcomes were measured using VISIA imaging, standardized photographs, and the Quality of Life Scale, with safety assessments included. RESULTS: Of the 90 participants, 80 completed the study. Both Group J and Group Y showed significant improvements in skin wrinkles, texture, radiance, and laxity compared to the control group (p < 0.05). No significant differences were found in physical health improvements (p > 0.05). CONCLUSION: The devices showed effectiveness in improving facial skin aging but require further safety verification. The potential of meridian theory integration should be explored further, with a focus on device design and user-friendliness for future research.
