RESUMO

BACKGROUND: Current literature suggests relatively low accuracy of multi-class wound classification tasks using deep learning networks. Solutions are needed to address the increasing diagnostic burden of wounds on wound care professionals and to aid non-wound care professionals in wound management. OBJECTIVE: To develop a reliable, accurate 9-class classification system to aid wound care professionals and perhaps eventually, patients and non-wound care professionals, in managing wounds. METHODS: A total of 8173 training data images and 904 test data images were classified into 9 categories: operation wound, laceration, abrasion, skin defect, infected wound, necrosis, diabetic foot ulcer, chronic ulcer, and wound dehiscence. Six deep learning networks, based on VGG16, VGG19, EfficientNet-B0, EfficientNet-B5, RepVGG-A0, and RepVGG-B0, were established, trained, and tested on the same images. For each network the accuracy rate, defined as the sum of true positive and true negative values divided by the total number, was analyzed. RESULTS: The overall accuracy varied from 74.0% to 82.4%. Of all the networks, VGG19 achieved the highest accuracy, at 82.4%. This result is comparable to those reported in previous studies. CONCLUSION: These findings indicate the potential for VGG19 to be the basis for a more comprehensive and detailed AI-based wound diagnostic system. Eventually, such systems also may aid patients and non-wound care professionals in diagnosing and treating wounds.

RESUMO

Midazolam and fentanyl, in combination, are the most commonly used medications for conscious sedation in day aesthetic surgeries. Dexmedetomidine is popularly used in the sedation protocol of our hospital due to its reduced respiratory depression. However, its sedation benefits in facial aesthetic surgeries, like blepharoplasty, have not been well-evaluated. We retrospectively compared individuals sedated with midazolam and fentanyl bolus injection (N = 137) and those sedated with dexmedetomidine infusion (N = 113) to determine which is more suitable for blepharoplasty with a mid-cheek lift. The total amount of local anesthetic (p < 0.001), postoperative pain (p = 0.004), ketoprofen administration (p = 0.028), and the number of hypoxia episodes (p < 0.001) and intraoperative hypertension (p = 0.003) were significantly lower in the dexmedetomidine group. Hypoxia severity (p < 0.001) and minor hematoma formation (p = 0.007) were also significantly lower in the dexmedetomidine group. Sedation with dexmedetomidine infusion is associated with less hematoma formation than sedation with midazolam and fentanyl bolus pattern due to hemodynamic stability and analgesic effects. Dexmedetomidine infusion may be a good alternate sedative for lower blepharoplasty.

RESUMO

BACKGROUND: Correcting puffy eyelids is important for improving the first impression. The puffiness is most predictable corrected by tissue resection and fat excision. Fold asymmetry, overcorrection, and recurrence can sometimes occur after levator aponeurosis manipulation. The objective of this study was to introduce a method of volume-controlled blepharoptosis correction (VC) without levator manipulation. METHODS: The medical records of patients who had undergone upper blepharoplasty between 2017 and 2022 were retrospectively reviewed. Questionnaires, digital photographs, and charts were used to evaluate the surgical outcomes and complications. The degree of levator function was graded as poor, fair, good, or very good. Levator function must be above good (>8 mm) to employ the VC method. Poor and fair grades of levator function were excluded because they require levator aponeurosis manipulation. The margin to reflex distance (MRD) 1 was assessed preoperatively, 2 weeks postoperatively, and at follow-up visits. RESULTS: Postoperative satisfaction was 4.3 ± 0.8 with no postoperative discomfort (0%), and the duration of swelling was 10.1 ± 2.0 days. Regarding other complications, no fold asymmetry (0%) was observed, although hematoma formation was observed in 1 (2.9%) patient in the VC group. Significant differences were observed in the changes in palpebral fissure height over time (p < 0.001). CONCLUSIONS: VC can effectively correct puffy eyelids and create natural-looking, beautiful, and thin eyelids. Thus, VC is associated with higher patient satisfaction and surgical longevity without serious complications.

RESUMO

OBJECTIVE: Lymphedema, especially in the advanced stage, is a growing challenge in extremity reconstruction, with few applicable surgical methods. Despite its importance, no consensus has been reached regarding a single surgical method yet. Herein, the authors introduce a novel concept of lymphatic reconstruction yielding promising results. METHODS: We included 37 patients with advanced-stage upper extremity lymphedema who underwent lymphatic complex transfers, consisting of both lymph vessel and node transfers, from 2015 to 2020. We compared the preoperative and postoperative (last visit) mean circumferences and volume ratios between the affected and unaffected limbs. Changes in the Lymphedema Life Impact Scale scores and complications were also investigated. RESULTS: The circumference ratio (affected to unaffected limbs) improved at all measuring points (P < .05), while the volume ratio showed a decrease from 1.54 to 1.39 (P < .001). The mean Lymphedema Life Impact Scale decreased from 48.1 ± 15.2 to 33.4 ± 13.8 (P < .05). No donor site morbidities, including iatrogenic lymphedema or any other major complications, were observed. CONCLUSIONS: A new technique for lymphatic reconstruction, lymphatic complex transfer, may be useful in cases of advanced stage lymphedema because of its effectiveness and the low possibility of donor site lymphedema.

RESUMO

Background In breast reconstruction, synthetic meshes are frequently used to replace acellular dermal matrix (ADM), since ADM is expensive and often leads to complications. However, there is limited evidence that compares the types of substitutes. This study aimed to compare complications between materials via a network meta-analysis. Methods We systematically reviewed studies reporting any type of complication from 2010 to 2021. The primary outcomes were the proportion of infection, seroma, major complications, or contracture. We classified the intervention into four categories: ADM, absorbable mesh, nonabsorbable mesh, and nothing used. We then performed a network meta-analysis between these categories and estimated the odds ratio with random-effect models. Results Of 603 searched studies through the PubMed, MEDLINE, and Embase databases, following their review by two independent reviewers, 61 studies were included for full-text reading, of which 17 studies were finally included. There was a low risk of bias in the included studies, but only an indirect comparison between absorbable and non-absorbable mesh was possible. Infection was more frequent in ADM but not in the two synthetic mesh groups, namely the absorbable or nonabsorbable types, compared with the nonmesh group. The proportion of seroma in the synthetic mesh group was lower (odds ratio was 0.2 for the absorbable and 0.1 for the nonabsorbable mesh group) than in the ADM group. Proportions of major complications and contractures did not significantly differ between groups. Conclusion Compared with ADM, synthetic meshes have low infection and seroma rates. However, more studies concerning aesthetic outcomes and direct comparisons are needed.

RESUMO

BACKGROUND: Correcting infraorbital hollowness is an important procedure for midface rejuvenation. Sub-orbicularis oculi fat lift is a commonly used method. However, adipose tissue, which has been thought of as sub-orbicularis oculi fat, has recently been controversial. The objective of this study was to introduce a method of midface rejuvenation using deep nasolabial fat lift (MRDN) by means of lower blepharoplasty and to compare surgical outcomes between MRDN and lower blepharoplasty with fat transposition (LBF). METHODS: The medical records of patients who had undergone midface rejuvenation with lower blepharoplasty between 2013 and 2020 were retrospectively reviewed. Questionnaires, digital photographs, and charts were used to evaluate the surgical outcomes and complications. The degree of aging was graded as mild, moderate, or severe. LBF and MRDN were used for mild and severe grades, respectively. For the moderate grade, the preferred surgical method of the two methods was selected and surgical outcomes were compared. The MRDN technique included LBF. RESULTS: Postoperative satisfaction was significantly higher ( P < 0.001), recurrence rate for tear trough ( P = 0.046) and fat bulging ( P = 0.005) was significantly lower, duration of swelling ( P < 0.001) was significantly longer, and incidence of chemosis ( P = 0.024) was significantly higher in the MRDN group than in the LBF group. Regarding lid malposition, transient retraction was higher in the LBF group, whereas cicatricial ectropion was higher in the MRDN group; however, these differences were not significant. CONCLUSION: MRDN is associated with higher patient satisfaction and surgical longevity without serious complications than LBF. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

RESUMO

AIMS: Transcutaneous oxygen pressure (TcPO2) is a reliable predictor of wound healing in diabetes patients; however, measurements are cumbersome. Previously, we demonstrated that skin hydration in the feet of patients with diabetic foot ulcers (DFU) is influenced by microcirculation rather than peripheral nerve function. Furthermore, skin hydration level before recanalization can predict wound healing better than TcPO2. This study investigated the skin hydration level cutoff value to predict DFU healing. METHODS: We retrospectively enrolled 834 patients with DFU. Wound healing outcomes were graded as healed without amputation or with minor/major amputation. Receiver operating characteristic analysis was used to evaluate the ability of skin hydration to predict wound healing outcomes and determine the optimal cutoff value for subsequent analyses. RESULTS: Average skin hydration values in the healed without and with amputation groups were 25.0 ± 7.4 arbitrary units (a.u.) and 17.5 ± 5.7 a.u., respectively (P < 0.001). The healing rate without amputation increased with skin hydration. A skin hydration value ≥ 21 a.u. significantly lowered the incidence of amputation. The cutoff value was 21 a.u. [(Youden's index, sensitivity, specificity, P-value) = (1.6, 92, 69.6, P < 0.001)]. CONCLUSIONS: A minimal skin hydration value of 21 a.u. is required for diabetic wound healing.

RESUMO

Skin flaps are necessary in plastic and reconstructive surgery for the removal of skin cancer, wounds, and ulcers. A skin flap is a portion of skin with its own blood supply that is partially separated from its original position and moved from one place to another. The use of skin flaps is often accompanied by cell necrosis or apoptosis due to ischemia-reperfusion (I/R) injury. Proinflammatory cytokines, such as nuclear factor kappa B (NF-κB), inhibitor of kappa B (IκB), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and oxygen free radicals are known causative agents of cell necrosis and apoptosis. To prevent I/R injury, many investigators have suggested the inhibition of proinflammatory cytokines, stem-cell therapies, and drug-based therapies. Ischemic preconditioning (IPC) is a strategy used to prevent I/R injury. IPC is an experimental technique that uses short-term repetition of occlusion and reperfusion to adapt the area to the loss of blood supply. IPC can prevent I/R injury by inhibiting proinflammatory cytokine activity. Various stem cell applications have been studied to facilitate flap survival and promote angiogenesis and vascularization in animal models. The possibility of constructing tissue engineered flaps has also been investigated. Although numerous animal studies have been published, clinical data with regard to IPC in flap reconstruction have never been reported. In this study, we present various experimental skin flap methods, IPC methods, and methods utilizing molecular factors associated with IPC.

RESUMO

BACKGROUND: Autologous material remains the preferred graft material for use in rhinoplasty. However, resorption rates of autografts remain controversial. In addition, long-term follow-up studies on autografts are rare. Thus, the objective of the present study was to access long-term resorption rates of various autologous grafts on the upper nasal third. METHODS: Medical records of patients who had undergone septorhinoplasty with dorsal augmentation using autologous tissues between 2009 and 2018 were retrospectively reviewed. Autogenous grafts applied on the nasal dorsum were categorized into three groups: rolled superficial mastoid fascia, diced cartilage wrapped with superficial mastoid fascia, and rolled sacral dermis. Preoperative and postoperative photographs were used to evaluate resorption rates and projection. RESULTS: The rolled sacral dermis group showed a steep increase in postoperative projection but a sharp decrease in long-term follow-up projection compared to the other two groups. Among these three groups, there were statistically significant trend differences in rhinion (p < 0.001) and ½ nasion-rhinion point (p < 0.001), but not in nasion. Of these three groups, the rolled sacral dermis group showed the most projection, followed by the diced cartilage wrapped with superficial mastoid fascia group. The resorption rate was the highest in the rolled superficial mastoid fascia group (p < 0.001). Regarding resorption rates in the other two groups, the rolled sacral dermis group had a higher rate than the diced cartilage wrapped with superficial mastoid fascia group. CONCLUSIONS: At least 50 percent of resorption was observed in almost all groups in the long term. The choice of graft material and proper decision-making could determine success or failure. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

RESUMO

BACKGROUND: Nontuberculous mycobacteria are commonly found pathogens; however, skin and soft tissue infections due to nontuberculous mycobacteria are often associated with surgical procedures, particularly after lipoplasty. Although nontuberculous mycobacteria are resistant to some chemical disinfectants, glutaraldehyde, peracetic acid, povidone iodine, alcohol, and chlorine are still used for the sterilization of medical instruments. This study investigated the efficacy of various disinfectants in a fatty environment with adipose and a bloody environment without adipose. In addition, this study was also used to identify the most effective disinfectant against nontuberculous mycobacteria. METHODS: Three nontuberculous mycobacteria (Mycobacterium avium, M. abscessus, and M. fortuitum), pathogens frequently found in skin and soft tissue infections, were used. Seven chemical disinfectants were tested in both fatty and bloody environments. The disinfectants used were considered to have a sterilization effect when the log10 reduction factor exceeded 5. RESULTS: Most disinfectants had some sterilizing effects against nontuberculous mycobacteria; however, glutaraldehyde was the most effective against all 3. Chlorhexidine and povidone iodine also displayed sterilizing effects. Of the disinfectants tested, only alkyldiaminoethylglycine hydrochloride showed a diminished effect with statistical significance, specifically against M. fortuitum in a fatty environment, whereas it had effective results in a bloody environment. CONCLUSIONS: Glutaraldehyde showed the greatest sterilizing effect on nontuberculous mycobacteria with a log10 reduction factor >5 in both fatty and bloody environments. However, some chemical disinfectants did not show sufficient sterilizing effects in a fatty environment and, therefore, should be used with caution for the sterilization of nontuberculous mycobacteria. LEVEL OF EVIDENCE: Level II.

RESUMO

OBJECTIVE: The purpose of this study was to compare clinical outcomes after vascularized lymph node transfer (VLNT) for the treatment of lymphedema performed on the upper and lower extremities. METHODS: Between April 2015 and January 2020, 71 patients with advanced-stage lymphedema, categorized as International Society of Lymphology late stage 2 or 3, who underwent VLNT in upper and lower extremities were included in this study. Thirty-seven and 34 patients underwent VLNT in upper and lower extremities, respectively. The circumference of the affected and unaffected extremities was measured at baseline, follow-up visits, and at the last visit. The circumference was measured in six places on the extremities, and the circumference and volume percent differences between the affected and unaffected extremities were calculated. First, we compared preoperative and postoperative extremity circumferences in the overall, upper, and lower extremity groups. Second, we compared circumference and volume percent differences between the affected and unaffected extremities calculated at the last visit to identify the degree of improvement by VLNT in the upper and lower extremity groups. RESULTS: The results of the comparative analysis between the preoperative and postoperative extremity circumferences showed that all postoperative extremity circumferences measured at the last visit were decreased compared with the preoperative values in the overall, upper, and lower extremity groups. In the upper extremity group, the circumference percent difference measured at the elbow was 23.1% before surgery and decreased to 13.4% at the last visit (P < .001). In the lower extremity group, the circumference percent difference measured at the knee was 24.4% before surgery and decreased to 17.4% at the last visit (P = .003). In the results of comparative analysis between the upper and lower extremity groups, there was a statistically significant difference in the postoperative circumference percent differences at the elbow/knee calculated at the last visit (P = .048). Similarly, there were statistically significant differences in circumference percent differences in two of six measurement sites at the last visit between the upper and lower extremity groups. However, there was no statistically significant difference in the volume percent difference calculated at the last visit between the upper and lower extremity groups. CONCLUSIONS: These results demonstrate that VLNT may be effective in treating patients with advanced-stage lymphedema. However, patients with upper extremity lymphedema demonstrate superior outcomes compared with those with lower extremity lymphedema.

RESUMO

PURPOSE: Endoscopic breast surgery for patients with breast cancer was introduced for its superior cosmetic outcomes; it was initially studied in the field of breast-conserving surgery and, more recently, in robotic-assisted nipple-sparing mastectomy (NSM). The main purpose of this study was to investigate the feasibility and safety of endoscopic NSM (E-NSM) in patients with breast cancer by comparing E-NSM and conventional NSM (C-NSM). METHODS: Between May 2017 and October 2020, we retrieved the records of 45 patients who underwent NSM with permanent silicone implants and divided them into the E-NSM group (20 patients) and the C-NSM group (25 patients), depending on the use of the endoscopic device. We also analyzed demographic information, pathology, operative time, and complications. RESULTS: No significant differences were observed between the 2 groups based on demographic information, postoperative pathological data, mean length of hospital stay, and total number of complications. The mean preparation time for surgery was comparable between both groups. Compared to the C-NSM group, the E-NSM group had a significantly longer mean operative time and, subsequently, a significantly longer mean total operative time and number of complications. CONCLUSION: The results showed that E-NSM was feasible and safe with a more inconspicuous incision in patients with breast cancer.

RESUMO

In many aging individuals, dermatochalasis and involutional ptosis appear together. Therefore, for functional and aesthetic purposes, ptosis correction and upper blepharoplasty are performed together. The aim of this article is to investigate factors that should be considered in order to achieve good results when simultaneously performing involutional ptosis correction and upper blepharoplasty in aging patients. Involutional ptosis is usually corrected through aponeurosis advancement in mild cases. In moderate or severe ptosis, the Muller muscle and aponeurosis are used together to correct ptosis. Using the two muscles together has the advantages of reducing lagophthalmos and increasing the predictability of outcomes after surgery. Broadly speaking, the surgical method used for involutional ptosis varies depending on the specific case, but unlike congenital ptosis, it is often not necessary to perform overcorrection. In particular, if there are problems such as severe dry-eye symptoms or risk of lagophthalmos, undercorrection should be considered. When performing ptosis correction, the surgeon should be careful not to overdo skin excision; instead, limited excision should be performed. After ptosis surgery, the brow may descend and the double fold may look too small. However, in order to make the double eyelids look larger, the surgeon should consider making the double eyelid design high rather than excising an excessive amount of skin. In some cases, to obtain more natural double eyelids and favorable results, it may be necessary to perform a sub-brow lift or forehead lift before or after involutional ptosis surgery.

RESUMO

BACKGROUND: Since the 1900s, many methods have been developed to correct the epicanthal fold. Increased use of epicanthoplasty has yielded unsatisfactory results. OBJECTIVES: To describe a method of epicanthal fold reconstruction using V-Y advancement and turnover flap for clinical application. This method is simpler than conventional surgery. It is easy to perform with excellent esthetic results. METHODS: The authors performed medial epicanthal fold reconstruction in 82 patients (16 males and 66 females) between April 2014 and September 2017. All patients enrolled in this retrospective study underwent surgical procedures at the authors' institution. Interepicanthal distance was the distance between medial epicanthal folds. It was measured with a surgical ruler. RESULTS: Before surgery, mean interepicanthal distance was 35.4 mm. Using our surgical technique, successful outcome was achieved in 79 (96.3%) patients with satisfactory results. The mean distance between the medial epicanthi post-surgery was 38.6 mm, increasing the total length by 3.2 mm without showing any major postsurgical complications. DISCUSSION: Epicanthal fold reconstruction using V-Y advancement and turnover flap is a simple and effective technique that can readily improve the frontal view. It improves periorbital contouring, makes eyes look natural without fully showing the caruncle, and yields excellent esthetic results. In particular, there were no major visible scars following eversion suture.

RESUMO

BACKGROUND: Paranasal augmentation has commonly been performed utilizing alloplastic materials such as silicone or porous polyethylene. However, there are problems such as bone absorption, implant migration, and infection risk attributable to intraoral approaches. OBJECTIVES: The authors attempted anterior positioning of the alar crease junction as an adjunct method of rhinoplasty. The authors aimed to determine the long-term results of the intranasal approach for placement of multi-folded expanded polytetrafluorethylene (ePTFE). METHODS: A retrospective review was conducted of patients who underwent intranasal surgical approach for paranasal augmentation employing multi-folded ePTFE implants in 19 septorhinoplasties who were followed-up for 3 to 10 years. Patient charts were reviewed for demographic information, concomitant operations, and complications. Preoperative and postoperative photographs were utilized to evaluate operative outcomes. The photographs were reformatted to 2-dimensional images employing standard photographic methods. RESULTS: Of the 19 patients treated, 17 were female and 2 were male; ages ranged from 18 to 58 years. All patients reported improvement in their lateral profiles and were pleased at follow-up. There were no major complications, no nerve or vascular supply compromise, and no cases of implant malposition. The average increase in soft tissue outline near the alar crease junction was more than 3.2 mm (P < 0.001), but the alar base did not became wider. CONCLUSIONS: Paranasal augmentation with multi-folded ePTFE is a simple, safe, and effective method that can readily improve the lateral profile. In particular, the intranasal approach combined with rhinoplasty can synergistically improve outcomes and lead to greater patient satisfaction.

RESUMO

BACKGROUND: In the diabetic foot, the skin may crack and develop fissures, potentially increasing vulnerability to ulceration and infection. Therefore, maintaining adequate skin hydration may be crucial for diabetic wound healing. However, no clinical study has addressed this issue. This study aimed to determine and compare the effect of the skin hydration level on diabetic wound healing with that of the tissue oxygenation level, which is recognized as the most reliable parameter in predicting diabetic wound healing. METHODS: This retrospective study included 263 diabetic patients with forefoot ulcers. Skin hydration and transcutaneous oxygen pressure data collected before and after percutaneous transluminal angioplasty were analyzed. Skin hydration and tissue oxygenation were graded as poor, moderate, or acceptable. Wound healing outcomes were graded as healed without amputation, minor amputation, or major amputation. Wound healing outcomes were compared using four parameters: skin hydration at baseline, transcutaneous oxygen pressure at baseline, post-percutaneous transluminal angioplasty skin hydration, and post-percutaneous transluminal angioplasty transcutaneous oxygen pressure. RESULTS: Each of the four parameters exhibited statistically significant correlations with wound healing outcomes. In the concurrent analysis of both skin hydration and transcutaneous oxygen pressure, skin hydration was a dominant parameter (p = 0.0018) at baseline, whereas transcutaneous oxygen pressure was a dominant parameter (p < 0.0001) following percutaneous transluminal angioplasty. CONCLUSIONS: Skin hydration level might be a useful predictor for diabetic wound healing. In particular, the skin hydration level before recanalization was found to be superior to transcutaneous oxygen pressure in predicting wound healing. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

RESUMO

BACKGROUND: Korean males and a few females desire to have larger eyes; however, they often wish to enlarge their eyes and conceal their double eyelids. This paper attempts to describe how to make the eyes bigger and brighter without showing double-fold eyelids. METHODS: The authors performed cosmetic ptosis correction in 121 cases from April 2013 to December 2017. All patients enrolled in this retrospective study underwent surgical procedures at the author's institutions. Patients were included that had mild-to-moderate degrees of ptosis and levator function greater than 5 mm, ages greater than 16 years, and no prior ptosis surgery. RESULTS: A successful outcome was achieved with this surgical approach in 113 (93.4%) patients. Complications potentially associated with ptosis surgery were not observed. DISCUSSION: A refined method of preoperative evaluation for incisional ptosis correction to conceal a double fold with no visible signs of surgery is described. Ptosis correction without the formation of double eyelids will result in skin hooding and visible scarring, and thus, it is recommended to lower the height of the double eyelids.
