Comparison of dual-plane micro-drop injection of botulinum toxin type A with two traditional methods for treating hypertrophic scars in the tension zone: A long-term clinical application study.

Patients with hypertrophic scarring tend to experience recurrence after treatment, which often occurs in areas of the body with high skin tension. To evaluate better treatments aimed at reducing the risk of scar recurrence in areas of high skin tension. Patients were randomly divided into the following three treatment groups: botulinum toxin type A (BTA) via dual-plane micro-drop injections, triamcinolone acetonide (TAC) suspension, and CO2 via fractional CO2 laser. Interventions were implemented in all three groups once a month for three consecutive sessions. After the final treatment, scarring was evaluated at 1, 3, 6, 12, and 24 months using the Patient and Observer Scar Assessment Scale (POSAS). The 3-month POSAS score for each scar indicator in the treatment groups was significantly lower than that in the preoperative groups (p < 0.001). The scar score in the TAC group decreased at 3 months and increased thereafter. For other groups, the scar score continually decreased at all time points according to the Patient Scar Assessment Scale. Based on the Observer Scar Assessment Scale, the scar score continuously decreased at all time points in the BTA group; in the TAC group, it decreased at 1 month and increased thereafter; and in the CO2 group, the scar score decreased at 3 months and subsequently stabilized. All three treatment methods were effective. However, the BTA group experienced a reduced risk of scar recurrence and maintained long-term treatment effects.

IMPLANTABLE MEDICAL DEVICES: A NON INVASIVE AND COSMETIC FRONTIER FOR WOUND CLOSURE

Abstract Cardiovascular implantable electronic devices (CIEDs) implantation procedures have undergone continuous improvement. Every aspect of the procedure can contribute to these improvements, including incision closure. The aim of this study was to assess the accuracy and validity of a non–invasive method using adhesive skin closure strips for wound closure of CIEDs in older adults, instead of surgical suture, evaluating parameters such as infection, erythema, skin reaction, itching, pain, oedema, time for closure, cosmetic outcomes and patients’ satisfaction. A retrospective study was carried out in 152 subjects (mean age 81 +9.3 years).undergoing application of adhesive strips after CIEDs substitution/implant and 132 usual care control subjects (mean age 76.6+8.9). Variables considered were: age, gender, risk factors for wound complications. Wound evaluation was conducted by using the Visual Analogue Scale (VAS) and the Patient and Observer Scar Assessment Scale (POSAS). Operative time for closing the incision and for removing sutures or strips were significantly lower in both application and removal in the adhesive strip group. At follow–up evaluations, each parameter considered by evaluation of the patients and staff was significantly better than in the control group. Fewer complications were observed in the patients undergoing wound closure wit adhesive strips. Previoulsy, to the best of our knowledge, the use of adhesive strips in closing surgical wounds of patients undergoing CIEDs implant/replacement has never been considered. Adhesive strips for wound closure of CIEDs incision are characterized by shorter procedural time, optimal early and late cosmetic results, fewer complications in older patients and is cheaper. Its use for CIEDs wound closure is reasonably supported.

A Novel Method for Patients With Ear Keloid: Enucleation and Fat Grafting.

Keloid is a dermal fibroproliferative disease unique to humans. Due to the ambiguity in its pathophysiology and the frequent recurrence of keloid, there is no clear consensus on the treatment of keloid and there are many treatment methods defined. In order to benefit from the positive effects of fat grafting on pathological scars, we applied fat grafting to patients who underwent keloid enucleation. Fifteen ear keloid patients included in the study. All patients underwent the same surgical procedure by the same surgeon. Routine follow-ups and examinations were performed to evaluate the results and in addition, the Patient and Observer Scar Assessment Scale (POSAS) survey was used. In the study, 15 patients were followed for a median (IQR) period of 21 (13-28) months. No recurrence was observed in any patient during follow-up, which occurred for a median of 21 (13-28) months. In the questionnaire filled out by the patients, the preoperative median value was found to be 48 (IQR: 12), whereas the postoperative median value was found to be 14 (IQR: 8). According to the patients, there was a statistically significant (P < 0.05) positive improvement after surgery. Historically, surgical procedures were avoided because the surgical recurrence rate was very high, but today, recurrence rates are decreasing with combined treatments. These treatment combinations may require more than one intervention and require frequent clinical follow-ups. With our technique of fat grafting after enucleation, the treatment was completed with a single operation and no additional intervention was required.

SUTURE CHOICE IN CARPAL TUNNEL SURGERY: A RANDOMIZED CONTROLLED TRIAL

ObjectiveCarpal tunnel release surgery is a commonly performed procedure for alleviating symptoms of median nerve compression and restoring hand function. With pressure on theatre time these procedures are now commonly performed in a step-down out-patient facility under local anaesthetic. The choice of suture for skin closure in this procedure can impact the quality of wound healing, patient outcomes and the follow-up required however the question of the best type of suture remains unanswered. The purpose of this study was to compare the outcomes of absorbable and non-absorbable sutures using a randomised control trial design.MethodsEighty patients diagnosed with bilateral carpal tunnel syndrome were enrolled and underwent outpatient carpal tunnel release surgery under local anaesthetic in a staged fashion. Random number generation was used to assign each hand to receive interrupted nylon or Vicryl Rapide sutures. Pre-operative data collection included patient demographics, ASA, inflammatory conditions, smoking status as well as a Boston Carpal Tunnel Questionnaire (BCTQ) for each hand. Patients were followed up at 2 and 6 weeks after each operation and the BCTQ was repeated along with the Patient and Observer Scar Assessment Scale and the VAS score for wound discomfort. This study has approval from the DHB ethics committee, Local Iwi, HDC and ANZ Clinical Trials:ACTRN12623000100695.ResultsStatistical analysis assessed patient preference and the scores between the groups. Multi-variate analysis was performed to assess the factors that may be contributing to patient choice.ConclusionInsights into patient preference and clinical outcomes associated with absorbable sutures and non-absorbable sutures in the setting of out-patient surgery are discussed.

Octyl-2-cyanoacrylate Tissue Adhesive Closure Versus Subcuticular Suture for Post-Auricular Incisions.

Skin closure techniques in otolaryngology vary based on surgeon preference and wound site. Octyl-2-Cyanoacrylate may be a safe, rapid, and cost-effective option for post-site closure. This randomized controlled trial study aimed to compare Octyl-2-Cyanoacrylate and conventional subcuticular sutures in ear surgeries, assessing wound closure results in both case and control groups. This prospective, randomized, controlled, single-blind study was conducted at Ohud Hospital from May 2021 to May 2022. Ear surgery and cochlear implantation in patients were examined, and each group was randomly assigned to receive Dermabond TM and deep layer subcuticular sutures closure. Incisions were assessed at various time points, including 3 weeks, 6 weeks, 6 months, and 1 year post-surgery. The patient and observer Scar Assessment Scale was used, and two independent ear surgeons used the Stony Brook Scar Evaluation Scale for initial scar assessment. This study involved 126 ear surgery and cochlear implantation patients randomized to use cyanoacrylate tissue adhesive or subcuticular suture for port site closure. The study found that tissue adhesive (OCA) was faster and more efficient than standard sutures, saving an average of 12 min per incision in each ear. Incision cosmesis showed immediate results and significant differences, and patient satisfaction with OCA wound closure was higher than standard sutures. The findings confirmed that cyanoacrylate tissue adhesive significantly reduced the time needed for skin closure during ear surgery and showed immediate cosmetic improvements without any documented instances of bleeding, hematoma, infection, or wound separation. This is a randomized controlled trial, it follows Level 2 of evidence. Randomized trial or observational study with dramatic effects Laryngoscope, 2024.

Reconstruction of Multiple Lip and Facial Defects With Bipaddle and Sensate Radial Forearm Free Flap.

Free flaps and their modifications are used to reconstruct multiple large defects in the lip and face. In this study, we present our results on the reconstruction of these defects using bipaddle and sensate free radial forearm-palmaris longus flaps and subsequent revision surgeries. Patient medical records of 11 patients with a mean age of 63.9 ± 12.8 years were retrospectively reviewed. Functional oral competence, lip cosmetics, lip sensation, and donor forearm scars were evaluated using the drooling rating scale, visual analog scale, Semmes Weinstein Monofilament test, and patient and observer scar assessment scale, respectively. The mean dimensions of distal and proximal skin paddles of bipaddle free radial forearm-palmaris longus flaps were 12.7 ± 9.9 and 20.5 ± 3.8 cm2. Mean lengths of the bridge and proximal pedicles were 4.7 ± 1.6 and 5.5 ± 0.7 cm. All the flaps survived. No drooling was observed in the 2 patients without lower lip defects. The mean drooling scores of the 9 patients with lower lip defects were statistically different (Analysis of Variance, pANOVA < 0.00001) at 3, 6, 9, and 12 months postoperatively. The differences between 3 and 12 months were the most significant (pANOVA < 0.00001, pTUKEY < 0.000001). The lip sensation and drooling scores showed a strong positive correlation (r = 0.8504). All patients were able to speak fluently, drink fluid without leakage, and blow a balloon easily. All patients and observers were satisfied with the lip cosmetics, with no significant difference between satisfaction scores (P = 0.087615).There was a statistically significant difference (P < 0.00001) between mean sensation scores of surrounding healthy lip (2.94 ± 0.27) and free flaps (4.15 ± 0.4). All the donor scars healed uneventfully.

Long-Term Comparison of Esthetic Outcomes Between Hatchet and Transposition Flaps in Facial-Defect Reconstruction.

Transposition flaps are commonly used for facial-defect repair after wide excision of skin cancers. However, such repair often causes excessive tension at the donor site that can result in distortion of the adjacent area. The hatchet flap, a rotation-advancement flap, can prevent distortion by redistributing the donor site tension evenly to the recipient site. This study aims to compare the esthetic outcomes of the hatchet flap and transposition flap in facial-defect reconstruction. We retrospectively included 50 patients who underwent facial reconstruction with the hatchet flap or transposition flap after excision of skin cancer. They were followed up for more than 6months. At the last follow-up visit, the esthetic outcome was evaluated by subjective and objective assessments using the patients and observer scar assessment scale and Manchester scar scale. Thirty patients and 20 patients underwent reconstruction using the hatchet flap and the transposition flap, respectively. The total score from the patient and observer scar assessment scale was significantly lower in the hatchet flap group compared with the transposition flap group (p = 0.009). The Manchester scar scale showed a total score of 7.67 ± 2.2 for the hatchet flap and 9.95 ± 1.99 for the transposition flap: in the color (p < 0.001), distortion (p < 0.001), and texture (p < 0.02) categories, the hatchet flap yielded significantly better outcomes than the transposition flap. The hatchet flap had good esthetic outcome for facial reconstruction and could be a valuable option for reconstructing facial defects.

Comparative study on outcome of intralesional steroid and combination of intralesional steroid with 5-fluorouracil in keloid treatment

Background: Though the definitive management of keloids are not yet established, many treatment modalities have been described which are being used alone or in combination all over the world with some promise. This study aims to assess the effect of intralesional steroids and 5-fluorouracil (5-FU) in the treatment of keloids. Methods: The study included 40 patients with keloids, out of which 20 received 6 doses of intralesional steroid and the other 20 received alternating three doses of intralesional steroid and three doses of 5-FU. The size of the keloid and the POSAS (Patient observer scar assessment scale) score were marked on the proforma and the patient was reassessed after 6 months. The decrease in volume and POSAS score was statistically analysed using paired and unpaired t tests. Results: There is a statistically significant decrease in POSAS score after intervention in both the steroid and steroid+5 FU groups. However, the decrease in POSAS score is significantly more in the group that received steroids alone. The group that received steroids had a greater decrease in volume (50% reduction) compared to the group that received the steroid-5FU combination (27% reduction). Conclusions: There is a statistically significant decrease in POSAS score after intervention in both the steroid and steroid+5 FU groups. However, the decrease in POSAS score is significantly more in the group that received steroids than the group that received steroid-5 FU combination.

A prospective study to assess cervical scar satisfaction following conventional open thyroidectomy for thyroid cancer.

Conventional open thyroidectomy (COT) remains a common method of thyroidectomy in many parts of the world for various reasons. In this prospective (cross-sectional) study, we evaluated the scar satisfaction among patients and surgeons following COT using the Patient and Observer Scar Assessment Scale (POSAS) and the Patient Scar Assessment Questionnaire (PSAQ). A total of 116 patients were included. The median age of the patients was 44years and the majority were women. The median scar length overall was 12.2cm. On POSAS, the median score for surgeon 1 was 1 (range 1-5), for surgeon 2, it was 2 (range 1-6), and for the patient, it was 1 (range 1-6) suggesting good scar satisfaction. The patient's response in the PSAQ was also echoing similar outcomes with scar satisfaction. Overall, both the patients and the surgeons seem to be satisfied with the overall scar appearance following COT despite the scar length.

Application and effect of tension-reducing suture in surgical treatment of hypertrophic scar

PurposeTo investigate the application and effectiveness of tension-reducing suture in the repair of hypertrophic scars.MethodsA retrospective analysis of clinical data was conducted on 82 patients with hypertrophic scars treated at the Department of Burns and Plastic Surgery of Nanjing Drum Tower Hospital from September 2021 to December 2022. Patients were operated with combination of heart-shaped tension-reducing suturing technique and looped, broad, and deep buried (LBD) suturing technique or conventional suture method. Outcomes of surgical treatment were assessed before and 6 months after surgery using the Patient and Observer Scar Assessment Scale (POSAS) and the Vancouver Scar Scale (VSS).ResultsImprovements were achieved on scar quality compared to that preoperatively, with a reduction in scar width (1.7 ± 0.6 cm vs. 0.7 ± 0.2 cm, P < 0.001). Assessment using the POSAS and VSS scales showed significant improvements in each single parameter and total score compared to preoperative values (P < 0.05). The Combination method group achieved better score in total score of VSS scale, in color, stiffness, thickness and overall opinion of PSAS scale, and in vascularity, thickness, pliability and overall opinion of OSAS scale.ConclusionThe amalgamation of the heart-shaped tension-reducing suturing technique and the LBD suturing technique has shown promising outcomes, garnering notably high levels of patient satisfaction in the context of hypertrophic scar repair. Patients have exhibited favorable postoperative recoveries, underscoring the clinical merit and the prospective broader applicability of this approach in the realm of hypertrophic scar management.

The Use of Fish Skin Grafts in Children as a New Treatment of Deep Dermal Burns-Case Series with Follow-Up after 2 Years and Measurement of Elasticity as an Objective Scar Evaluation.

Background: Wound healing in deep dermal burn injuries continues to be a challenge in paediatrics. In the absence quick and spontaneous wound closure, split-thickness skin grafting is often necessary. Since the development of a new type of acellular fish matrix, which is very similar to the human skin matrix, skin closure and wound conditioning can be achieved without split-thickness skin grafting. Methods: The following study shows a case series of 20 children in whom a fish skin graft was used. The aim was to develop an algorithm for selecting and using fish skin and its long-term results after one and two years. Acellular fish skin worked as a granulation base for wound healing and also as a substitute for split-thickness skin grafts. Results: There was no evidence of infection. Skin transplants and, thus, additional operations could be avoided. The follow-up examinations showed an excellent result, both objectively by means of elasticity measurements (DermalabCombo®) and in the subjective assessment of the skin as part of the Patient and Observer Scar Assessment Scale (POSAS). Conclusion: Fish skin grafts are a good alternative to split-thickness skin grafts for deep dermal wounds. These results should be further analysed with a larger number of patients in future publications.

Analysis of trends and status of evaluation methods in thyroid scar

BackgroundThe incidence of thyroid cancer has increased over the decades, and patients prefer short thin scars after thyroidectomy due to their cosmetic visibility. Several scar assessment methods have been used to determine the most cosmetically optimal surgical method, but a widely accepted measurement tool is still lacking. This study investigates the usage status in the thyroid scar scale according to time, region, and study method. MethodsThe authors searched for articles on thyroid scars published between January 2000 and September 2022 in the PubMed database. The study included clinical studies that mentioned thyroid scar and scar scale, excluding articles that did not evaluate neck scars. Statistical analysis was performed using IBM SPSS Statistics 29. ResultsA total of 35 studies were included. Among them, 17 used the Vancouver Scar Scale (VSS), 17 used the Patient and Observer Scar Assessment Scale (POSAS), four used the Manchester Scar Scale (MSS), and four used the Stony Brook Scar Evaluation Scale (SBSES). VSS and POSAS were the most commonly used scar evaluation methods. VSS tended to be used frequently in Asia, while POSAS was used frequently in Europe and in randomized controlled trials. ConclusionVSS and POSAS are popular thyroid scar assessment methods, with regional variations. Standardization is needed for meaningful comparisons. Patient's subjective evaluations should be considered, given the cosmetic importance of thyroid scars.

Prospective Evaluation of Fractional Carbon Dioxide Laser Treatment of Mature Burn Scars, Post-traumatic Scars, and Post-acne Scars.

Annually, around 100 million patients worldwide acquire scars, some of which can cause significant problems. Various treatment interventions, such as topical scar creams, steroids, laser therapy, and surgery, have been developed to manage these scars. This study was conducted to evaluate the effectiveness of fractional CO2 laser treatment by assessing outcomes using the Patient Observer Scar Assessment Scale (POSAS) and clinical photographs. A total of 47 patients were included in the study, divided into three groups: a post-acne scar group with 14 patients, a post-burn scar group with 17 patients, and a post-traumatic scar group with 16 patients. Detailed histories were taken, and clinical examinations were performed and recorded on a prepared proforma. Aesthetic outcomes were evaluated based on clinical photographs, and total patient and observer scores were recorded using POSAS at baseline, and after one and three months. POSAS comprises two components: the observer scale (POSAS-O) and the patient scale (POSAS-P). Fractional CO2 laser treatments were performed in each group, with sessions repeated every four weeks for three consecutive sessions. Data were analyzed using the paired t-test for before-and-after comparisons in each study group. Welch's ANOVA test was used for comparisons among the three groups at a significance level of p=0.05, using MS Excel(Microsoft Corporation, Redmond, Washington) and IBM SPSS Statistics for Windows, Version 20 (Released 2011; IBM Corp., Armonk, New York). The mean age for men was 26.38 ± 8.19 years and for women 22.21 ± 6.38 years. The study comprised 34 female patients (72.34%) and 13 male patients (27.66%). The mean POSAS observer and patient scales were recorded and compared for all three types of scars from baseline to three months. The mean percentage change in POSAS-O and POSAS-P (total score) in relation to different scar sites was recorded. The most significant difference in mean percentage change, statistically significant (p-value < 0.05), was observed for facial scars, followed by scars on the neck, and was minimal for scars on the hand, in both observer and patient groups. Even a single session of fractional CO2 laser therapy had profound effects on the overall quality of scars. Fractional carbon dioxide laser therapy improves the quality of scars and produces significant improvements in skin texture, with better effects on post-traumatic scars than on post-burn and post-acne scars. Future studies are needed to better understand the mechanism of action and to optimize the doses and timing of therapy.

The Impact of Platelet-Rich Plasma Application during Cesarean Section on Wound Healing and Postoperative Pain: A Single-Blind Placebo-Controlled Intervention Study.

Background/Objectives: The aim of this study was to evaluate if platelet-rich plasma (PRP) application into the wound during cesarean delivery improves wound healing and reduces pain in the postoperative period. Materials and Methods: A total of 46 patients undergoing cesarean section (CS) were included in this single-blind placebo-controlled intervention study: 23 women in the PRP group and 23 in the placebo group. Every patient was asked to evaluate pain by using the Visual Analogue Scale (VAS) immediately after surgery, as well as 6 and 12 h after the surgery. The use of analgetics was also recorded. The postoperative scar was assessed using the Patient and Observer Scar Assessment Scale (POSAS). Results: There was no case of wound dehiscence in either group. Significant differences between the groups in the scar quality assessment were detected in both patient and doctor POSAS results on days 8, 30 and 90 after surgery in the favor of the PRP group. There was no difference in the pain intensity assessment on the VAS recorded after surgery, but PRP patients required fewer paracetamol doses per day than the control group. Conclusions: PRP application during CS significantly improved wound healing in both short- and long-term assessment. Although it did not influence postoperative pain intensity, it may reduce the use of analgetics after surgery.

Effective keloid management using a combinatorial continuous-wave and repeat fractionated ablative CO2 laser regimen.

Keloids are benign proliferative scars that form as a result of dysregulated growth and collagen deposition in response to cutaneous injury. Laser therapies have emerged as promising options for the treatment of keloids, with performance varying by laser type and lesion characteristics. To assess the combined continuous wave and repetitive fractionated CO2 laser treatment of keloids. A retrospective chart review of 22 cases of keloid scars treated with combined CO2 laser modes. A single session of continuous wave followed by five sessions of fractional delivery. Efficacy was assessed using the Patient and Observer Scar Assessment Scale (POSAS) and the Vancouver Scar Scale. The Numeric Rating Scale was used to assess patient satisfaction and pain. Most patients were female (77.3%) with skin type IV (72.7%), age was 24.3 ± 9.3 years, most keloids were located on the earlobe (56.5%) or arm or hand (17.4%), size ranged from 5 to 10 cm, and time since injury ranged from 3 months to 35 years. No serious adverse events were reported. At 6 months, significant improvements from baseline occurred in all characteristics, scar color (4.8 ± 2.8 to 1.9 ± 1.1), rigidity (5.0 ± 2.8 vs. 5.4 ± 2.8), thickness (5.4 ± 2.8 vs. 2.0 ± 1.1), and irregularity (5.9 ± 2.4 vs. 1.9 ± 0.9). The Vancouver scores followed a similar trend. Patient-rated overall improvement from 37 ± 17.6 at baseline to 16.1 ± 8.5 at 6 months, and improvement in associated pain and pruritus. Combination of two ablative laser delivery modes within a single laser platform provided for effective and safe keloid management and left patients highly satisfied.

Study of Outcome of Diathermic Incision Cautery more than 5 cms in General and Urologic Surgery Operations

Introduction: Cutting diathermy is a more recent alternative to scalpel for surgical incisions. Its use was limited due to fear of increased risk of infection, impair healing and decrease cosmesis. However, recent studies suggest otherwise, claiming that diathermy may offer potential advantages with respect to blood loss, incision time and post-operative pain. The aim of this study was thus to evaluate the outcome of diathermic incision in terms of healing, post-op pain and scar characteristics in operations with incisions more than 5 cm in size. Materials &amp; Methods: A hospital based observational study included 182 cases scheduled to undergo surgery requiring more than approximately 5 cm of incision. Cases were operated by surgeons who have a minimum of 3 years of experience. Incision time, wound healing, post-op pain and scar characteristics were noted at discharge and follow up at 7th and 30th day. Results: Mean incision time was 24.5 seconds with almost half of the cases (48.9%) had incision time between 20-30 seconds. A significant improvement was observed in all cases regarding mean Southampton wound score and pain score from day of discharge till day 30th of follow up. A significant improvement was also observed in patient and observer scar assessment scale in all the sub categories from day of discharge till day 30th of follow up None of the cases complaint of any surgical site infections or scar related complications. Conclusion: Electrocautery can be considered as effective and safe in making large skin incision. It is associated with less incision time, faster healing, low post-operative pain and good scar characteristics.

Assessing Scar Outcomes Using Objective Scar Measurement Tools: An Adjunct to Validated Scar Evaluation Scales.

The assessment of scar outcomes is important to both patient care and research focused on understanding the results of medical and surgical interventions. The Vancouver Scar Scale and Patient and Observer Scar Assessment Scale are validated and simple instruments to assess scars. However, these subjective scales have shortcomings. The VSS fails to capture patient perception and has indeterminate validity and reliability. The POSAS captures patient perception, but the observer scale has been shown to have moderate amounts of inter-rater variability. Studies highlighting the ability of objective scar assessment tools to produce reliable and reproducible results are needed. In this study, we aimed to validate the use of the Fibrometer ®, Elastimeter ®, and SkinColorCatch ® as an objective adjunct in the assessment of hypertrophic scar and keloid outcomes. This was a prospective single-center study which assessed patient scars using the Vancouver Scar Scale, the Patient and Observer Scar Assessment scale, and the aforementioned objective study tools. Correlations between the different methods of scar assessment were measured. The Fibrometer ® and SkinColorCatch ® showed significant correlations with the VSS total and the Observer POSAS total. The Elastimeter ® showed significant correlations with both the Patient and Observer POSAS totals. Unexpected correlations between Elastimeter ® measurements and the vascularity/pigmentation of scars indicate that scoring of these categories may be influenced by how severe the scar looks to the observer subjectively, further necessitating the need for reliable objective scar assessment tools. These results highlight the ability of these devices to assess scars and demonstrate their potential in serving as an important adjunct to previously validated scar assessment scales.

Knotless suture in revision total joint arthroplasty: a prospective randomized controlled trial.

The use of barbed sutures for wound closure in primary total joint arthroplasty (TJA) has been shown to be effective and safe. However, their effectiveness and safety in revision TJA procedures has not been thoroughly studied. This study aims to evaluate the efficacy and safety of using barbed suture closure in revision TJA setting. A total of 80 patients undergoing revision TJA between September 2020 and November 2022 were included in this randomized controlled trial study. Following informed consent, patients were computer-randomized to the treatment arm (barbed suture wound closure) or to the control arm (conventional wound closure). Closure duration, closure rate, number of sutures used and wound related outcomes including complication rates and Patient and Observer Scar Assessment Scale (POSAS) score were compared between groups. The use of barbed sutures decreased closure time by 6min (30.1 vs. 36.1min, P = 0.008) with a higher wound closure rate (6.5 vs. 5.5mm/minute, P = 0.013). Additionally, the number of sutures used for wound closure in the barbed group was significantly lower than in the control group (6.2 vs. 10.1, respectively, P < 0.001). There were no significant differences in the rate of postoperative wound complications (P = 0.556) or patient and observer POSAS scores (P = 0.211, P = 297, respectively) between the two groups at 3-month follow-up. Closure of revision TJA surgical wound utilizing barbed sutures reduced closure time and the number of needles handled by operative staff, with no significant increase in intra- or post-operative complications rate when compared to traditional closure technique.

Advanced Facial Rejuvenation: Synergistic Effects of Lower Blepharoplasty and Ultrasound Guided Mid-Face Lift Using Polydioxanone (PDO) Threads

BackgroundTraditional facial aging surgeries have risks and extended recovery times, leading to a demand for minimally invasive alternatives. PDO (polydioxanone) threads, which are absorbable sutures that stimulate collagen production and tissue contraction, offer improved aesthetic outcomes. This paper evaluates the combined use of PDO thread mid-cheek lift and lower blepharoplasty for facial rejuvenation.MethodsThis retrospective study compared outcomes in patients undergoing lower blepharoplasty combined with a mid-face lift using PDO threads versus those undergoing only lower blepharoplasty. Focused on individuals with baggy lower eyelids and pronounced nasolabial folds, outcome measures included the Modified Fitzpatrick wrinkle scale, Allergan® midface volume deficit scale, Width of inter zygomatic distance, Patient and Observer Scar Assessment Scale, and patient satisfaction questionnaires, assessed at baseline, 3 months, and 1 year postoperatively.ResultsThe combined procedure demonstrated superior aesthetic outcomes and higher patient satisfaction compared to lower blepharoplasty alone. Improvements were more significant in wrinkle reduction, midface volume, and inter-zygomatic distance in the combined procedure group. Although the combined procedure had a longer mean operation time, scar assessment scores were similar between both groups, with no complications reported.ConclusionThe combination of lower blepharoplasty and mid-face lift using PDO threads is a comprehensive and effective approach for facial rejuvenation. It significantly enhances wrinkle reduction, mid-face lifting, and patient satisfaction. Ultrasound-guided thread lifting, a method of assessing and performing mid-face lifting, proves to be safe and efficient. This approach holds promise as a future option in cosmetic anti-aging surgery, presenting a minimally invasive alternative with natural-looking results and reduced downtime.Level of Evidence IIThis journal requires that authors assign a level of evidence to each article.
