Donor Site Morbidity after Removal of FullThickness Peroneus Longus Tendon Graft for Anterior Cruciate Ligament (ACL) Reconstruction: 4-Year Follow-up.

PUSPOSE OF THE STUDY. Many studies have investigated the efficacy of peroneus longus tendon (PLT) in anterior cruciate ligament (ACL) reconstruction, and donor site morbidity has not been adequately studied. MATERIAL AND METHODS: Fifty patients who underwent ACL reconstruction using PLT were included. Ankle strengths of the patients evaluated with an analog dynamometer. Ankle range of motion (ROM) was measured with a smart phone inclonometer application. RESULTS: There was no significant difference between the postoperative ankle strength(eversion, plantar flexion) in the donor area and the preoperative period (p=0.6 and p=0.7, respectively) and contralateral healthy side (p=0.6, p=0.6, respectively). Ankle ROM angles (dorsiflexion, plantar flexion, eversion, inversion) were significantly lower in the post-operative period compared to the preoperative period and contralateral healthy side (p<0.05, p<0.05, p<0.05, p<0.05, respectively). There was no significant difference between pre-operative and post-operative AOFAS scores (p=0.2). CONCLUSIONS: Although PLT can affect ROM angles, it is a promising alternative for ACL reconstructions without causing functional morbidity. KEY WORDS: peroneus longus tendon, autograft, anterior cruciate ligament reconstruction, donor site morbidity.

Comparing Different Donor Sites After Vascularized Lymph Node Transfer to the Lymphedematous Upper Limb: A Systematic Review and Meta-analysis of Clinical Outcomes.

BACKGROUND: Vascularized lymph node transfer (VLNT) involves the microvascular transplantation of functional lymph nodes from a donor site into a limb affected by lymphedema to restore the normal flow of lymphatic fluid. Despite the increasing clinical experience with VLNT, there remains insufficient data to support its routine use in clinical practice. Here, we aim to evaluate the effectiveness and safety of VLNTs for upper limb lymphedema and compare clinical outcomes when using different donor sites. METHODS: We carried out a systematic search of the literature through PubMed and Scopus databases for studies on VLNT for upper limb lymphedema. Primary and secondary outcomes included circumference reduction rate (CRR) and infection reduction rate by postoperative cellulitis episodes for the efficacy and safety of VLNT. Pooled analysis was performed using the inverse variance weighting meta-analysis of single means using the meta package in R software. Subgroup analyses were performed for donor and recipient sites, age groups, follow-ups, and symptom durations. Quality assessment was performed using the Newcastle-Ottawa Scale for nonrandomized studies. RESULTS: A total of 1089 studies were retrieved from the literature, and 15 studies with 448 upper limb lymphedema patients who underwent VLNT were included after eligibility assessment. The mean CRR was 34.6 (18.8) and the mean postoperative cellulitis episodes per year was 0.71 (0.7). The pooled analysis of CRR was 28.4% (95% confidence interval, 19.7-41.1) and postoperative cellulitis episodes showed a mean of 0.59 (95% confidence interval, 0.36-0.95) using the random-effect model. Subgroup analyses showed significant group differences in recipient site for CRR and postoperative cellulitis episodes with the wrist comprising the highest weights, and patients younger than 50 years showing a lower postoperative infection. CONCLUSIONS: Vascularized lymph node transfer using gastroepiploic flaps at the wrists has shown a significant difference in reductions of limb circumference and cellulitis episodes in upper limb lymphedema patients when compared with other donor sites. However, further prospective studies are needed to consolidate this finding.

Comparison of the effect of A-PRF and L-PRF application to palatal donor sites on quality of life and wound healing after free gingival graft surgery.

OBJECTIVES: This study compared the effects of leukocyte platelet-rich fibrin (L-PRF) and advanced platelet-rich fibrin (A-PRF) on patients' quality of life and the healing of palatal wounds after free gingival graft harvesting. METHOD AND MATERIALS: After free gingival graft harvesting, palatal donor sites of 36 patients were assigned to one of three groups: L-PRF group, A-PRF group, or palatal stent + periodontal pack group (control group). Wound healing was evaluated by H2O2 test. Pain was evaluated by visual analog scale and number of analgesics consumed. For patient quality of life, the Oral Health Impact Profile-14 (OHIP-14) questionnaire was utilized. RESULTS: Complete epithelialization was higher in the control group on day 7 than in the test groups (P < .05). Complete epithelialization was achieved in all groups 14 days postoperatively. Visual analog scale scores for pain and the number of analgesic tablets consumed were similar in all groups (P > .05). OHIP-14 total scores were similar in all study groups at 7 days postoperatively (P > .05). OHIP-14 total and physical pain score was lower in the L-PRF group than the A-PRF group at 14 days postoperatively (P < .05). CONCLUSION: Aside from the slight superiority of L-PRF over A-PRF, it can be concluded that both PRF procedures have similar effects on palatal wound healing and quality of life.

Comprehensive analysis of donor-site chest deformities after autologous costal cartilage microtia reconstruction: A systematic review.

BACKGROUND: Autologous costal cartilage has gained widespread acceptance as an important material for ear reconstruction in patients with microtia. Despite its recognition as being "worth the trade-off," attention should be directed toward donor-site deformities. This systematic review focused on existing English literature related to microtia reconstruction and aimed to reveal the incidence of chest wall deformities and assess the effectiveness of the various proposed surgical techniques aimed at reducing donor-site morbidities. METHODS: A comprehensive search was conducted on Pubmed and OVID using the keywords "microtia," and "chest deformity" or "rib harvest." Articles were screened based on predefined inclusion and exclusion criteria. Data acquisition encompassed patient demographics, employed surgical techniques, methods for evaluating chest deformity, and incidence of associated complications. RESULTS: Among the 362 identified articles, 21 met the inclusion criteria. A total of 2600 cases involving 2433 patients with microtia were analyzed in this review. Perichondrium preservation during cartilage harvesting led to a significant reduction in chest deformities. However, the wide incidence range (0% to 50%) and the lack of specific assessment methods suggested potential underestimation. Computed tomography revealed reduced chest wall growth in the transverse and sagittal directions, resulting in decreased thoracic area. Innovative surgical techniques have shown promising results in reducing chest deformities. CONCLUSIONS: Although a quantitative analysis was not feasible, objective evidence of deformities was established through computed tomography scans. This analysis highlighted the need for dedicated studies with larger sample sizes to further advance our understanding of chest wall deformities in microtia reconstruction.

Double right triangular shape full-thickness skin grafts technique for short rectangular or square shape donor site defect - original method with a case report.

Full-thickness skin grafts are essential tools for reconstructive surgery. Rectangular or square secondary defect usually occurs after performing a cross-finger flap or homodigital island flap. With the traditional fusiform ellipse design, trimming out excess graft tissue is necessary. Double right triangular shape full-thickness skin grafts are designed to correct the problem.

Medial sural artery perforator free flap versus radial forearm free flap in oral cavity reconstruction and donor site morbidity.

OBJECTIVE: Radial Forearm Free flap (RFFF) is widely used in head and neck reconstruction, yet its donor site defect remains a significant drawback. The Medial Sural Artery Perforator Free Flap (MSAPFF) is considered an alternative flap to RFFF. This study aims to comprehensively analyze their characteristics, outcomes, and their impact on patient quality of life. METHODS: All patients who underwent oral cavity reconstruction using RFFF and MSAPFF between February 2017 and April 2023 were included in this study. Flap characteristics, outcomes and post-operative complications were recorded and compared. Subjective donor site morbidity, aesthetic and functional results, and quality of life were also analyzed. RESULTS: The study included 76 patients: 37 underwent reconstruction with RFFF, and 39 with MSAPFF. There was no significance difference between the RFFF and MSAPFF regarding the success rate (97.2% vs 97.4%), flap size (4.8 × 8.8 cm2 vs 5 × 9.8 cm2), hospital of stay (15.5 days vs 13.5 days) and recipient site complications (P > 0.05). However, MSAPFF showed larger flap thickness (P = 0.001), smaller arterial caliber (P = 0.008), shorter pedicle length (P = 0.001), and longer harvesting time (P < 0.001). No significant difference was observed between the pre-and postoperative ranges of wrist and ankle movements or in recipient site complications. MSAPFF showed a significant difference in donor site morbidity (P < 0.05). CONCLUSION: The MSAPFF is an excellent alternative to the RFFF for repairing oral cavity defects, with additional advantage of a well-hidden scar on the posterior calf, a larger flap thickness, accepted pedicle length and arterial caliber. However, one should consider the harvesting time and surgical skills required in comparison to the RFFF. CLINICAL RELEVANCE: The study highlights the importance of the MSAPFF as an alternative option for RFFF with less donor site morbidity and high success rate in oral cavity reconstruction and improved patient Quality of life after ablative surgery.

Ultrasonographic analysis of palatal donor site healing accelerated with platelet-rich fibrin following subepithelial connective tissue harvesting.

OBJECTIVE: Platelet-rich fibrin (PRF) contains a variety of growth factors and bioactive molecules that play crucial roles in wound healing and angiogenesis. We aimed to evaluate the effects of PRF on tissue thickness and vascularization of the palatal donor site by ultrasound (USG) following subepithelial connective tissue harvesting. METHODOLOGY: A subepithelial connective tissue graft was harvested from the palatal region with a single incision for root coverage in 20 systemically healthy patients. In the test group (n = 10), the PRF membrane was placed at the donor site, whereas no material was applied in the control group (n=10). Palatal tissue thickness (PTT) and pulsatility index (PI) were evaluated by USG at baseline and on the 3rd, 7th, 14th, 30th, and 90th days after surgery. The early healing index (EHI) was used to evaluate donor site healing for 30 days. RESULTS: PTT was significantly higher in the PRF group on the 3rd and 14th days after surgery when compared to the controls. In the PRF-treated group, PI levels were significantly higher than in the controls, especially on the 14th day. PTT increased significantly 90 days after surgery compared to the test group baseline, but controls showed a significant decrease. The PRF group showed statistically significant improvements in EHI scores compared to controls on days 3, 7, and 14. This study found a negative correlation between PI values and EHI scores on postoperative days three and seven in the test group. CONCLUSION: USG is a non-invasive, objective method to radiographically evaluate the regenerative effects of PRF on palatal wound healing after soft tissue harvesting. To overcome graft inadequacy in reharvesting procedures, PRF application may enhance clinical success and reduce possible complications by increasing tissue thickness and revascularization in the donor area.

Does Fibula Free Flap Harvesting Affect Donor Site of Patients in Facial Reconstructions: A Gait Analysis Study.

BACKGROUND: Vascularized fibula free flap (VFFF) remains gold standard for reconstruction of bony defects of the maxilla or mandible. Research and publications in recent years essentially focused on the evolution and improvement of the recipient reconstructed area but very few concerning the donor site morbidity. PURPOSE: The aim of this study was to analyze walking ability of patients following VFFF operation and to determine if there are long term walking disabilities. STUDY DESIGN, SETTING, SAMPLE: The retrospective cohort study involved healthy controls and patients who had undergone VFFF between 2012 and 2019 at the oral and maxillo-facial department of the University Hospital in Lausanne, Switzerland. Patients with cardiovascular, pulmonary, neuromuscular or musculoskeletal pathologies that could impair walking were excluded from the study. PREDICTOR/EXPOSURE/INDEPENDENT VARIABLE: Primary predictor is the reconstruction status, VFFF versus healthy patients (controls). MAIN OUTCOME VARIABLES: Main outcomes were gait parameters. Objective evaluation of walking abilities was assessed using the Gait Up system (Gait Up SA, EPFL Innov'Park-C, Lausanne, Switzerland), which are wearable motion sensors that provides 3D analytics of the gait. COVARIATES: Covariates implied patient characteristics such as age, sex, time after surgery and subjective evaluation of the gait obtained with two orthopedic validated questionnaires. RESULTS: This study implied 10 healthy controls and 11 patients who had undergone VFFF. Results showed statistically significant differences in the speed [m/s] (1.3 vs 1.1 for a P value of .001), the stride length [m] (1.4 vs 1.2 for a P value of 0.003), the flat foot phase [%] (55.0 vs 63.3 for a P value of .006) and the pushing phase [%] (34.1 vs 25.1 for a P value of .008). CONCLUSION AND RELEVANCE: Reconstruction using vascularized autograft in maxillofacial surgery is substantial and well described. Our attention focusing on donor site morbidity has demonstrated subjective and objective long-term alterations. These results will have to be confirmed with gait analysis in a prospective project including preoperative and postoperative analysis of the gait of the patient acting himself as his own control, with a larger scale of patients.

Use of lateral femoral cutaneous nerve blocks by landmark technique is ineffective in decreasing narcotic usage after skin grafts: A retrospective case-control study.

INTRODUCTION: Cutaneous burns are commonly treated with autologous skin grafts. Following skin grafting, many patients complain of pain at the donor site. Donor sites are taken most commonly from the lateral thigh, which is innervated by the lateral femoral cutaneous nerve (LFCN). Use of a LFCN blocks should decrease nociception from the donor site. METHODS: Our group began utilizing LFCN blocks in 2019. Utilizing anatomic landmarks, LFCN blocks were performed on all patients who received autologous skin grafts to reduce perioperative pain. A retrospective cohort study was performed on all patients with 10% or less total body surface areas burns who received an autologous skin graft. A similar cohort from 2016, prior to use of any local or regional analgesia, was used as a historical control. Post-operative enteral and parenteral narcotic analgesics were collected for each post-operative day up to day 5 or discharge (whichever came first) and converted to morphine milligram equivalents (MME) to quantify analgesia after surgery. RESULTS: Chart review identified 55 patients in the 2020 cohort. Fifty-five patients from the 2016 cohort were matched based upon size of skin graft, total body surface area (TBSA) burned, gender, and age. There were no statistically significant differences between the two groups in terms of size of graft, TBSA burned, age, gender, or type of burn. When examining narcotics usage in the immediate perioperative period (days 0-2), we found no difference between the two groups for total MME (113 vs 133, p = 0.28) or IV MME (38 vs 33, p = 0.45). Similar relationships existed in the extended post-operative period (days 1-5) for total MME (149 vs. 188, t = 0.22) or IV MME (37 vs. 50, t = 0.25). Examining daily narcotic usage also yielded no statistically different values. CONCLUSION: Our data shows that use of LFCN block by landmark technique did not reduce narcotic usage in patients that undergo skin grafting procedures. Future studies should consider ultrasound-guided LFCN blocks.

[Robotic-Assisted DIEP Flap Harvest for Autologous Breast Reconstruction: Case Report, Technical Aspects and Identification of Suitable Patients]. / Die robotisch-assistierte Hebung der DIEP-Lappenplastik zur Brustrekonstruktion: Fallbericht, technische Aspekte und Identifikation geeigneter Patientinnen.

BACKGROUND: Robotic-assisted harvest of the deep inferior epigastric perforator (DIEP) flap is an innovative modification of the traditional open preparation for autologous breast reconstruction. It is assumed that donor-site morbidity (herniae, bulging) is reduced by minimising the fascial incision length in robotic-assisted DIEP flap harvest. MATERIAL & METHODS: This is the first report of a robotic-assisted DIEP harvest in Germany, which was performed in April 2023 at the University Hospital of Freiburg in an interdisciplinary approach of the Departments of Plastic Surgery, Urology and Gynaecology. To determine the value of this novel technique, we assessed the demand by retrospectively performing an analysis of potential patients and conducted a cost analysis based on the breast reconstructions with DIEP flap harvest performed between April 2021 and May 2023 at the Department of Plastic Surgery at Freiburg University Hospital. To this end, we carried out a retrospective analysis of preoperative CT angiographies to determine the proportion of patients suitable for a robotic-assisted procedure in a post-hoc analysis. Furthermore, we describe the basic robotic-assisted techniques and discuss the TEP and TAPP laparoscopic approaches. RESULTS: In line with the previously published literature, a short intramuscular course (≤25 mm) and a perforator diameter of≥1.5 mm and≥2.7 mm (subgroup) were defined as a crucial condition for the robotic-assisted procedure. We analysed 65 DIEP flaps harvested in 51 patients, of which 26 DIEP flaps in 22 patients met both criteria, i. e.≤25 mm intramuscular course and≥1.5 mm diameter of the perforator, while 10 DIEP flaps in 10 patients additionally met the criteria of the subgroup (≥2.7 mm diameter). Based on the intramuscular course of the perforators in the CT angiographies of those 26 DIEP flaps, a potential reduction of the fascial incision of 96.8±25.21 mm (mean±standard deviation) compared with the conventional surgical approach was calculated. The additional material costs in our case were EUR 986.01. However, ischaemia time was 33,5 minutes longer than the median of the comparative cohort. CONCLUSION: The robotic-assisted procedure has already proven to be a feasible alternative in a suitable patient population. However, further studies are needed to confirm that robotic-assisted DIEP flap harvest actually reduces harvest site morbidity and thereby justifies the additional costs and complexity.

Optimising oral cancer reconstruction: a retrospective cohort study on the modified radial forearm free flap technique to eliminate the need for a secondary donor site.

The radial forearm free flap (RFFF) is commonly used in the reconstruction of oral cancer patients. Traditional RFFF (TRFFF) techniques, which often require a secondary donor site to repair the forearm defect, may result in a scar extending to the dorsal hand. This can lead to significant functional and aesthetic concerns in the forearm. We designed a modified RFFF (MRFFF) that incorporates a glasses-shaped flap and features deep venous drainage. To evaluate its effectiveness we conducted a retrospective chart review of 105 patients with oral squamous cell carcinoma who underwent reconstructive surgery between 2018 and 2022. These patients were treated either with a TRFFF (n = 60) or the newly developed MRFFF (n = 45). Our inclusion criteria, guided by preliminary surgical experience prior to initiating the study, stipulated that single oral defects should be no larger than 6 × 6 cm2, and adjacent double defects no larger than 3 × 6 cm2. Flap size, pedicle length, harvesting duration, and anastomosis during the surgical procedure were compared between the two techniques. Preoperative and postoperative oral function, recurrence, mortality, and dorsal scarring were recorded. One-week, one-month, and six-month postoperative subjective aesthetics assessments, and self-reported postoperative donor hand function, were measured using the Michigan hand questionnaire (MHQ). There were no significant differences between the groups in terms of flap size, pedicle length, harvesting time, anastomosis time, postoperative oral function, recurrence, and mortality. However, patients with a MRFFF did not require a second donor graft site and did not have scars extending to the dorsal forearm. They also had significantly improved postoperative aesthetic outcomes (1 week: 70.6%, 1 month: 62.2%) and donor hand function (1 week: 54.6%, 1 month: 40.4%) compared with the TRFFF group (p < 0.001). The MRFFF eliminates the need for secondary donor sites and improves primary donor site outcomes. It is versatile and can be employed for either single or composite oral defects. Through extensive case studies, we have defined its specific scope: it is suitable for single defects measuring no more than 6 × 6 cm2, or for composite defects no larger than 3 × 6 cm2. Furthermore, it does not compromise the functional recovery of the recipient site, and should be widely adopted for all qualifying patients.

Reduction of the scar burden at the donor area of the radial forearm flap with the aid of an endoscopic pedicle preparation.

BACKGROUND: The radial forearm flap is one of the most commonly used flaps of reconstructive microsurgery with its long pedicle and thin structure. The donor site at the forearm is a visible anatomic region that has high mobility and functional importance. In this study, a longitudinal and large scar was avoided on the forearm during pedicle dissection of the conventional radial forearm flap with the utilization of an endoscope. Furthermore, arterial, venous, and nervous injuries were avoided by performing a separate inci-sion of 2-3 cm at the cubital fossa to reduce flap failure and donor site morbidity. METHODS: The patients who underwent pedicle dissection of the radial forearm flap with the aid of an endoscope for head-neck reconstruction between 2014 and 2021 were included in this study. The flap was harvested from the subfascial plane. The cephalic vein was used in all of the patients. When the pedicle dissection reached the antecubital region, an incision of 2-3 cm was performed from the skin. Two vein anastomoses were performed for each patient. RESULTS: This retrospective study consists of 51 patients. While 45 of the patients were the result of head and neck cancer, six of them had a defect caused by trauma. The average area of skin islands was 40.3 cm2, while the full-thickness skin graft size was 24.2 cm2. An average of 2.6 cm of scar tissue was formed at the antecubital region. No venous or arterial compromise was observed in the post-operative period. There was no partial or total flap loss in any patient. Localized numbness persisted in the skin area where the superficial sensory branch of the radial nerve is located in 6 (11.7%) patients. CONCLUSION: With endoscopic radial forearm flap harvesting, the longitudinal incision in the forearm and wound healing prob-lems are avoided. The absence of partial or total flap loss has shown that endoscopic harvesting of the radial forearm flap is a safe and reliable method.

Using an Elastomeric Skin Protectant to Manage Donor Site Wounds of Split-thickness Skin Grafts: A Case Series.

ABSTRACT: Split-thickness skin grafting (STSG) is a common surgical procedure to manage acute and chronic wounds. A plethora of dressings exists to treat STSG donor site wounds (DSWs). Recently, a new elastomeric skin protectant was adopted (Cavilon Advanced Skin Protectant; 3M) in the treatment of incontinence-associated dermatitis. In this report, the authors assess the effects of this elastomeric skin protectant as an alternative wound dressing for STSG donor sites.The authors report a single-center prospective case series that was performed to establish a treatment protocol. Nine consecutive patients with different indications for treatment with an STSG from May to September 2018 were included. Collected data included general patient information, comorbidities, complications, blood loss, pain during dressing change, and the duration of DSW healing.This case series showed promising results in terms of duration of DSW healing when applying the elastomeric skin protectant. The authors also observed less blood loss and less pain during dressing changes. No infections were seen during the trial.

An objective analysis of composite free flap donor site morbidity in head and neck surgery: Prospective series.

BACKGROUND: A poor evidence basis exists regarding the objective donor site morbidity associated with osseous free flap harvest. This study prospectively assessed the objective donor site morbidity associated with osseous free flap harvest for the fibula, scapula, and iliac crest (DCIA) donor sites. METHODS: A single-site, prospective cohort clinical research study was conducted. Sixty-four patients were recruited between 2017 and 2021. Patients were assessed using a donor site specific assessment tool pre-operatively, and again >12 months post-operatively. RESULTS: There was a significant reduction post-operatively in assessment tool scores compared to the pre-operative period for the fibula, scapula and DCIA. Females were more likely to report a greater reduction in Harris Hip Score post-operatively compared to males. CONCLUSIONS: The fibula, scapula, and DCIA donor sites are associated with reduced objective function post-operatively compared to patient's pre-operative baseline. The implications are least pronounced for the fibula.

Surgical technique and comparison of autologous cancellous bone grafts from various donor sites in rats.

Autologous cancellous bone graft is the gold standard in large bone defect repair. However, studies using autologous bone grafting in rats are rare. To determine the feasibility of autologous cancellous bone graft harvest from different anatomical donor sites (humerus, ilium, femur, tibia, and tail vertebrae) in rats and compare their suitability as donor sites, a total of 13 freshly euthanized rats were used to describe the surgical technique, determine the cancellous bone volume and microstructure, and compare the cancellous bone collected quantitatively and qualitatively. It was feasible to harvest cancellous bone grafts from all five anatomical sites with the humerus and tail being more surgically challenging. The microstructural analysis using micro-computed tomography showed a significantly lower bone volume fraction, bone mineral density, and trabecular thickness of the humerus and iliac crest compared to the femur, tibia, and tail vertebrae. The harvested weight and volume did not differ between the donor sites. All donor sites apart from the femur yielded primary osteogenic cells confirmed by the presence of alkaline phosphatase and Alizarin Red S stain. Bone samples from the iliac crest showed the most consistent outgrowth of osteoprogenitor cells. In conclusion, the tibia and iliac crest may be the most favorable donor sites considering the surgical approach. However, due to the differences in microstructure of the cancellous bone and the consistency of outgrowth of osteoprogenitor cells, the donor sites may have different healing properties, that need further investigation in an in vivo study.

A Single Centre, Randomized Control Trial Of Donor Site Wound Dressings After Split-Thickness Skin Grafting.

BACKGROUND: Split-thickness skin grafting (STSG) is a widely employed technique for repairing wounds, such as ulcers, trauma, or in reconstructive surgeries. The objective was to compare the efficacy of different dressing materials for healing donor-site wounds after split-thickness skin grafting. METHODS: A single center, randomized controlled trial was conducted at the Department of Plastic Surgery, Civil Hospital Karachi, Pakistan, over a period of six months. The study included patients aged 18 years and above, of both genders, who underwent single donor-site wounds after split-skin grafting with a surface area larger than 10 cm². The eligible patients were randomly divided into six groups: Film, Alginate, Gauze, Hydrofiber, Hydrocolloid, and Silicone. Pain, itching, scarring, complications, and patient satisfaction were evaluated after 12 weeks using standardized assessment scales. RESULTS: The median time to complete wound healing and re-epithelialization varied among the different dressing groups, with hydrofiber and silicone dressings demonstrating the shortest healing time. Statistical analysis revealed a significant difference in the median time to complete wound healing among the dressing groups (p-value=0.019). However, no significant differences were observed in pain, itching, scarring (POSAS observer and patient), or patient satisfaction among the different dressings (p-value>0.05). CONCLUSIONS: Although the dressing type did not significantly affect pain, itching, scarring, or patient satisfaction, variations were observed in the time to complete wound healing. These findings contribute to the selection of appropriate donor site dressings for optimizing outcomes in split-skin grafting procedures.

Comparative Analysis of the Treatment of Skin Lesions of the Lower Limbs with Sural Flap versus Propeller Flap / Análise comparativa do tratamento de lesões cutâneas dos membros inferiores com retalho sural versus retalho propeller

Abstract Objective The objective of the present study was to prospectively compare the sural and propeller flaps for soft-tissues coverage of the lower extremity. The following variables were evaluated: incidence of complete or partial flap loss and donor area morbidity (primary closure versus skin graft). Methods Prospective and randomized analysis of data collected from all patients presenting with soft tissue defects of the lower third of the leg and heel treated with reverse sural or propeller flaps. Results Twenty-four patients aged between 4 and 60 years old were evaluated between 2011 and 2017. Complete coverage was obtained in 22 of the 24 patients (91.6%). Two flaps failed (8.4%). The sural flap, being the most popular option, continues to represent a safe and versatile alternative for skin defects of the lower third of the leg and heel region. Likewise, the propeller flap was a comparable option to treat these challenging defects. Conclusion Sural and propeller flaps are good options for soft tissues coverage of the lower extremity, with low complication rates (partial or total flap loss).

Resumo Objetivo O objetivo do presente estudo foi comparar prospectivamente os retalhos sural e propeller para cobertura de partes moles da extremidade inferior. Foram avaliadas as seguintes variáveis: incidência de perda total ou parcial do retalho e morbidade da área doadora (fechamento primário versus enxerto de pele). Métodos Análise prospectiva e randomizada de dados coletados de todos os pacientes apresentando defeitos em tecidos moles da extremidade distal da perna e do retropé submetidos aos retalhos em questão. Resultados Foram avaliados 24 pacientes com idades entre 4 e 60 anos, entre 2011 e 2017. Cobertura completa foi obtida em 22 dos 24 pacientes (91,6%) e observamos falha em 2 retalhos (8,4%). O retalho sural, sendo a opção mais popular, continua a representar uma alternativa segura e versátil para defeitos cutâneos do terço distal da perna e da região do calcanhar. O retalho propeller, da mesma maneira, mostrou-se uma opção comparável para o tratamento destas lesões desafiadoras. Conclusão Os retalhos sural e propeller são boas opções para a cobertura de partes moles da extremidade inferior, demostrando baixas taxas de complicações como perda parcial ou total do retalho.

Relationship between Preoperative Abdominal Wall Strength and Bulging at the Abdominal Free Flap Donor Site for Breast Reconstruction.

BACKGROUND: Abdominal bulging at the donor site of free abdominal flaps for breast reconstruction is a common postoperative complication. In addition to the thickness of abdominal muscles, the authors identified the rectus abdominis diastasis as an important factor that compromises abdominal wall strength. This study aimed to assess the relationship between preoperative abdominal wall strength and postoperative abdominal bulging. METHODS: A total of 224 patients were enrolled in this study. Patient demographics, the rectus and lateral abdominis muscle thicknesses, and the rate of rectus abdominis diastasis were compared (with versus without bulging). Muscle thickness and rectus abdominis diastasis were investigated by preoperative computed tomography. RESULTS: The group with bulging consisted of 32 patients (14.3 percent), whereas the group without bulging consisted of 192 patients. The group with bulging had a significantly higher gestational history rate. The thickness of the rectus abdominis muscle in the group with bulging was significantly thinner (median, 8.6 mm versus 10.5 mm; p < 0.001) and the rate of rectus abdominis diastasis was significantly higher (78.1 percent versus 32.3 percent; p < 0.001). There were no significant differences with respect to the thickness of the lateral abdominal muscle and the other factors (i.e., age, body mass index, history of laparotomy. and operative details). CONCLUSIONS: Because the diagnosis of abdominal bulging was based on severity, the rate may be high compared to that reported from previous studies. Because the factor of gestational history correlated to thickness of the rectus abdominis muscle and rectus abdominis diastasis, this factor influenced the occurrence of abdominal bulging. Patients with a thin rectus abdominis muscle and rectus abdominis diastasis were at higher risk of abdominal bulging. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Application of autologous platelet-rich plasma to graft donor sites to reduce pain and promote healing.

OBJECTIVE: Platelet-rich plasma (PRP) is widely used for wound healing in medical care because of the numerous growth factors it contains. Traditionally, donor sites are left to heal with a primary dressing so wounds are not left open. However, a delay in healing accompanied by pain at a donor site is often seen. This study primarily throws light on the use of autologous PRP over split-thickness skin graft (STSG) donor sites to promote healing and reduce pain. METHOD: The patients enrolled in this study in 2018-2019 were divided into two groups: the intervention group received autologous PRP applied topically at the donor site; in the control group, the wound was dressed traditionally. Pain scales were measured in the immediate postoperative period at six hours, 10 hours and 16 hours. The dressing was opened on the postoperative day 14 and observed for healing by an independent observer. RESULTS: A total of 100 patients were included in the study. Patients in the PRP group showed statistically significant faster healing at postoperative day 14 compared with the control group (p<0.05), who required dressings for 3-4 weeks postoperatively. Pain scale scores in the postoperative period were significantly less in the PRP group at six hours postoperatively compared with the control group (p<0.05). There was a reduced incidence of hypertrophic scar formation in the small number of patients in the PRP group who had developed hypertrophic scar previously. CONCLUSION: Application of PRP is a safe, cost-effective and easy method to achieve faster healing in graft donor site areas that are troublesome to both patients and doctors. It also reduces postoperative pain at donor sites. The authors recommend PRP is used more often in the management of donor sites for STSGs.

Prophylactic fasciotomy of the anterolateral thigh donor site in head and neck reconstruction.

INTRODUCTION: The free anterolateral thigh (ALT) flap is a versatile reconstructive option for head and neck defects. Donor site complications are rare but severe; with wound dehiscence, need for secondary closure, and compartment syndrome reported. OBJECTIVES: We propose prophylactic thigh fasciotomy as a surgical technique to facilitate primary closure while preventing donor site complications during ALT flap harvest. METHODS: We examined donor site wound characteristics, recipient site wound characteristics, and clinical outcomes for 24 consecutive ALT flaps performed for head and neck reconstruction from 2016 to 2018. All ALT donor sites underwent prophylactic fasciotomy. RESULTS: There were no incidents of thigh compartment syndrome or wound dehiscence of donor site; one patient underwent primary donor site skin grafting. CONCLUSION: Prophylactic thigh fasciotomy allows mobilization of soft tissue to facilitate primary tension-free closure of the ALT donor site even for free flaps with a large skin component, while reducing the possibility of compartment syndrome.
