RESUMO

BACKGROUND: Among all post bariatric surgical procedures, vertical thigh lift has the highest complication rates. Many modifications have been described to achieve better aesthetic results and decrease complication rates. The study aimed to present ''Anchor L Liposculpture Technique'' and discuss the results in the light of current literature. METHOD: Between 2016 and 2020, 33 patients were operated with the Anchor L Liposculpture technique. In this technique, liposuction is performed similarly with the other techniques, but the liposuction area is not extended to posterior or anterior compartments to prevent complications. The technique also used a deepithelized flap to anchor the superficial fascial system to the pubic arch periosteum. The patients' characteristics (age, sex, body mass index, smoking history, amount of weight loss, comorbidities) volume of liposuction and postoperative complications were recorded. Results were compared between uncomplicated (group A) and complicated patients (group B). RESULT: Six (n=6, %18.2) out of 33 patients experienced complications (Group B). There were no major complication. The most common complications are wound dehiscence (n = 2) and lymphocele (n = 2). All complication cases managed conservatively. Age and amount of liposuction were found to be statistically associated with increased complications. Other comparisons between group A and B did not show any significant difference. Scar migration was not observed in any patient during follow-up. CONCLUSION: Anchor L Liposculpture technique is an easy-to-apply and reliable technique aimed better surgical results and lower complication rates. Surgeons especially at beginning of the learning curve or who experienced high complication rates can utilize this technique.

RESUMO

BACKGROUND: According to National Cancer Institute, there are approximately 39,800 rectal cancer cases per year, 25% of which will need an abdominoperineal resection (APR). The key to avoid most of the complications related to pelvic defect that occurs after APR is choosing an appropriate reconstruction option for perineum. This study aims to introduce an easily applicable flap option for closure to address postoperative pelvic defect in low rectal cancer. METHODS: This is a retrospective evaluation of 9 patients who have undergone perineal reconstruction for pelvic defects after extralevatory abdominoperineal excision with rectal cancer between 2014 and 2016. Reconstruction consists of a novel technique defined by our clinic, which is buried desepidermised fasciocutaneous V-Y advancement flap. RESULTS: All defects are closed successfully. Patients are followed postoperatively for complications such as perineal infection, wound dehiscence, seroma, perineal sinus, or fistula formation. Flaps are evaluated with magnetic resonance imaging postoperatively, for viability and effectiveness on defect closure. Mean follow-up time is 20 (±9) months. Mean average hospital stay is 8 (±2) days. We did not experience any total or partial flap loss or encounter any local complication related to the wound. CONCLUSIONS: Buried desepidermised fasciocutaneous V-Y advancement flap is a reasonably easy and time-saving operation. It is effective in filling the pelvic dead space while closing the sacral defect after APR and therefore decreases late term complications related to large perineal excision.

RESUMO

PURPOSE: The toll-like receptors (TLRs) stand at the interface of innate immune activation. We hypothesize to decrease the response of innate immunity activated by TLR4 by a safe, short-term, systemic immunosuppression. METHODS: Two silicone block implants were placed into two dorsal subcutaneous pockets in 32 rats that were subdivided into four groups: The two study groups were the IV DEX group (single intravenous injection of dexamethasone 1 h before surgery) and the IV DEX + IP DEX group (in addition to a single intravenous injection of dexamethasone 1 h before surgery, intraperitoneal dexamethasone was administered for 10 days after surgery), and the two control groups were the untreated control group and the saline-treated control group. After 10 weeks, all animals were killed to determine capsular thickness, inflammatory cell density, presence of pseudoepitheliomatous hyperplasia, edema, necrosis, vascularization, TLR4 expression and myofibroblast proliferation. RESULTS: No significant difference was observed in any parameter between the untreated and saline-treated control groups (p > 0.05). Capsular thickness, myofibroblast proliferation, TLR4 expression density were statistically different among study groups compared to control (p < 0.05). CONCLUSIONS: This study demonstrates the relationship between toll-like receptors and fibrous capsule after implant surgery. Decreasing the innate immunity by a safe, short-term perioperative systemic immunosuppression resulted in decreased TLR4 expression and myofibroblast differentiation which could be a new research field in profibrotic pathophysiology underlying breast capsule formation.

RESUMO

Reconstruction of the first ray is challenging because of poor skin laxity, bone and tendon exposure, and limited local flap options. Repair using full- or split-thickness skin grafts is generally not an option because of the bone and tendon exposure. Reconstructive options using local flaps from the distal foot area are restricted owing to insufficient soft tissue. Many reconstructive options have been described to overcome these difficult situations. We present 2 cases in which the great toe and first ray defect were repaired using a reversed first dorsal metatarsal artery island flap. The findings from these clinical cases and anatomic studies have shown that the reversed first dorsal metatarsal artery island flap is an alternative and suitable option for reconstruction of soft tissue defect of the distal foot, especially first and second ray defects, because it is thin and simple, has anatomic characteristics similar to those at the recipient site, and results in minimal donor site morbidity.

RESUMO

PURPOSE: The etiology of nasal septal perforations involves iatrogenic, traumatic, inflammatory, infectious, neoplastic, and caustic causes. To ensure successful closure, an appropriate interpositional graft material should be selected, and this graft material should be covered with healthy tissue. MATERIALS AND METHODS: The study included 18 New Zealand white rabbits weighing 2 to 2.5 kg. Nasal septal perforations were created in group 1. After the creation of defects in group 2, repair was performed with cartilage graft and bilateral mucoperichondrial advancement flaps. After septal nasal perforations in group 3, the defect was covered with fingernail and bilateral mucoperichondrial flaps. RESULTS: At week 12, the rabbits were sacrificed. The septum site that had been repaired with fingernail was intact. No nail exposition, wound site decomposition, or re-perforation was observed. No findings of a breach of the structural integrity of the fingernails or disintegration were encountered. CONCLUSION: Fingernails can be used as an interpositional graft material in place of cartilage in eligible cases for the repair of nasal septal perforations. Fingernails have several properties that enable their use in such cases, such as form preservation that is similar to cartilage, the lack of live cells, easy availability, and a lack of donor-site morbidity at removal.

RESUMO

Lip carcinoma is one of the most common cancers of the head and neck region. Lower lips are more frequently affected. Squamous cell carcinoma accounts for more than 95% of the cases. The aim of treatment is to achieve the highest cure rates with adequate excision with clear surgical margins while leaving the smallest defect sizes behind for reconstruction. Excised tissue is known to shrink when removed, in relation with its retractile properties. In this study, the evaluation of the amount of shrinkage in excised lip cancer specimens and determination of the relation between surgical and histopathologic margins were aimed. The study included 21 consecutive excised lip specimens for the treatment of squamous cell carcinoma of the lip. The volume of the specimen, tumor length, and margin distance measurements were measured and recorded step by step from before surgical excision to histopathologic evaluation. Specimens were evaluated in a standardized fashion by the same pathologist after 48 hours of fixation. For data analysis, Number Cruncher Statistical System 2007 and Power Analysis and Sample Size 2008 Statistical Software (Kaysville, UT) were used. The surgical margins of the excised lip specimen shrink up to 41% to 47.5% from before excision to histopathologic evaluation. The most significant step was the excision step, followed by the formalin fixation step. The histopathologic process itself and the duration of formalin fixation did not result a significant change in surgical margins. The tumor tissue itself did not show a significant shrinkage.

RESUMO

Frontal sinus fractures constitute 5% to 15% of maxillofacial fractures, and isolated anterior table injuries account for 33% of frontal sinus fractures. The treatment strategy of frontal sinus fractures should be individualized according to the extent of the injury. Endoscope-assisted repair without any fixation method for the treatment of mildly and moderately displaced (1-5 mm) and closed isolated anterior table frontal sinus fractures is a good alternative technique for treatment.Between April 2010 and December 2011, 5 patients with mildly and moderately displaced isolated anterior table fractures were treated. There were no lacerations in forehead skin of the patients. Preoperatively, the patients showed forehead depression at the fracture site, and computed tomography scan was taken to determine the extent of the frontal sinus fracture. Endoscope-assisted closed reduction treatment was applied to all patients.All fractures were reduced successfully. None of the patients needed to undergo conversion to traditional incision techniques. No patients required fixation materials. Cosmetic deformity was corrected in all patients perfectly.In the standard treatment modality of frontal sinus fractures, repair is best performed by a coronal approach. However, bicoronal incision has many disadvantages. Several authors have recently described some endoscopic and closed approaches to these injuries. The main disadvantages of these methods are poor visualization or fixation requirement with exogenous materials.Endoscopic reduction of mildly and moderately displaced closed isolated anterior table frontal sinus fractures without fixation is feasible. It results in a good clinical outcome in selected cases.

RESUMO

UNLABELLED: Chemical peeling is a noninvasive technique currently used more frequently as a cosmetic procedure. Trichloroacetic acid (TCA) is one of the most popular chemical agents used for this purpose Stuzin et al. (Clin Plast Surg 20:9-25, 1993). Although this application commonly is used for the whole face, including the eyelids, the data in the literature referring to ocular complications if TCA leaks into the eye and the injury treatment thereafter are too sparse. The authors therefore report the treatment procedure and follow-up evaluation for a patient who sustained a chemical injury to the eye during rhytidectomy combined with TCA peeling.

RESUMO

Hidradenitis suppurativa is a recurrent, chronic, and suppurative cutaneous disease of unknown etiology. Radical excision of all affected skin followed by flap coverage of the defect is the treatment method of choice in severe and recurrent cases. This study discusses the use of local islanded perforator flaps in the reconstruction of defects following excision of hidradenitis suppurativa lesions in axillary, gluteal, and inguinal regions. Eleven male patients (mean age of 39.3 years) underwent reconstruction of hidradenitis suppurativa defects with 13 local islanded perforator flaps. Three patients (one being bilateral) had gluteal, two patients (one being bilateral) had inguinal, and six patients had axillary involvement. The defects in the gluteal region were repaired with superior gluteal artery perforator flaps, inguinal defects were repaired with medial circumflex femoral artery perforator flaps, and the axillary defects were repaired with thoracodorsal artery perforator flaps. There was no total flap loss in the postoperative period, but one marginal necrosis and two wound infections occurred. There was no recurrence of hidradenitis suppurativa or revision requirement during the mean follow-up period of 11.5 months.

RESUMO

UNLABELLED: This article discusses the application of computer-aided design and rapid prototyping techniques in polymethylmethacrylate reconstruction of craniofacial bone defects. This method avoids the probability of tissue damage due to exothermic reaction during the polymerization process and provides precise implants that exactly fit the defects. METHODS: A total of 11 patients who have various-sized craniofacial defects underwent polymethylmethacrylate reconstruction. We performed three-dimensional reconstruction and operative design using computer software. According to the design, we determined the shape and size of the implants and made individualized implants for craniofacial bone defects with the rapid prototyping technique. RESULTS: With the application of computer-aided design and a rapid prototyping technique, we could accurately determine the shape, size, and embedding location. Prefabricating the individual implant models is useful in improving the accuracy of treatment. No cases of infection, seroma, extrusion, or contour irregularity occurred as a complication, and all patients were satisfied with the results. During the follow-up period, ranging from 1 to 6 years, all patients remained satisfied, and no complications were sustained. CONCLUSIONS: In cases of various-sized cranial defects and complex maxillofacial defects that have enough soft tissue coverage and that do not have contact with a third space, prefabricated methyl methacrylate implants can be used safely. Patients will feel more comfortable if the postoperative shape resembles the original appearance, so the proposed algorithm effectively creates a customized implant.

RESUMO

Ecthyma gangrenosum is a rare invasive cutaneous infection mostly caused by Pseudomonas aeruginosa in immunosuppressed patients, especially during neutropenic states. Embolic lesions usually accompanying with septicemia of P. aeruginosa are typically painless, round, and centrally necrotic with a surrounding erythematous halo. Facial involvement occurred only in 6% of the patients, which may result to complicated defects for reconstruction. In this article, we aimed to present a case with relapse of acute lymphoblastic leukemia presented to our clinic with 50% defect of the lower lip due to ecthyma gangrenosum and its late-term reconstruction.

RESUMO

Constricted ear deformity was first described by Tanzer and classified it into 3 groups according to the degree of constriction. The group IIB deformity involves the helix, scapha, and antihelical fold. The height of the ear is sharply reduced, and the soft tissue envelope is not sufficient to close the cartilage framework after expansion and reshaping.This study describes expanding the cartilage and increasing the height by advancing the helical root superiorly and repairing the skin-cartilage defect with a superior auricular artery chondrocutaneous flap in Tanzer group IIB constricted ear deformity.Six ears of 6 patients were treated with this technique during the past 3 years. All patients were satisfied with the appearance of their corrected ears, and the increase in height was maintained through the follow-up period.The described technique does not have the disadvantages and possible complications of harvesting a costal cartilage graft. Moving and fixing the root of helix to a more superior position provide the auricle with additional length. The superior auricular artery chondrocutaneous flap not only provides adequate soft tissue for primary closure of the anterior portion of the auricle but also aids in repairing the cartilage defect resulting from the superior advancement of the helix as well.

RESUMO

Temporomandibular joint ankylosis is a devastating condition for the patient associated with both functional disability and aesthetic deformities. Various techniques have been described in the literature to overcome this problem; however, there is still a high risk of reankylosis in patients undergoing multiple temporomandibular joint operations, severe heterotopic ossification, and fibrosis of the soft tissues. This study includes 5 patients with severe and recurrent ankylosis. Two-stage reconstruction with excision of the bony mass and placement of a distraction device in the first stage, followed by gradual distraction of soft tissues, and placement of a total joint prosthesis in the second stage were performed in all patients. The 2-step approach helps to overcome the fibrosis and adhesions in the soft tissues and allows placing an implant with a higher ramus component. This approach seems to be a useful and effective technique for the management of such patients with high risk of reankylosis.

RESUMO

OBJECTIVE: The tarsal plate is the skeleton support system of the eyelids; therefore, repair during eyelid reconstruction is crucial. Many autogenous graft materials have been proposed for the tarsal reconstruction, such as nasal cartilage, palatal mucosa, upper eyelid tarsus, and auricular cartilage. Nail thickness and shape are similar to the tarsal plate with enough support for the eyelid. It also easily integrates with host tissues. The aim of this experimental study was to macroscopically and histopathologically compare nail xenografts with cartilage autografts when used in eyelid reconstruction in rabbits. METHODS: In total, 12 New Zealand rabbits were used in the experiment. Full-thickness defect with a 1-cm diameter was created in both upper eyelids. The right upper eyelids were used for cartilage autograft reconstruction, and the left upper eyelids were used for nail xenograft reconstruction. All animals were killed on week 12 after eyelid reconstruction. After the animals were killed, the upper eyelids of the rabbits were resected for macroscopic and histologic analysis. RESULTS: In histologic evaluation, moderate foreign body giant cell formation and moderate histiocytic, neutrophilic, basophilic, and lymphocytic infiltration were observed in both experimental group and control group. In addition, this marked fibrous capsule formation was observed around the nail xenograft, which was absent in the cartilage autograft group. CONCLUSIONS: Nail has some advantages such as being cost-effective, being easy to obtain, and having less rejection risk for being composed of dead cells. Nail xenografts can be taken into account instead of cartilage grafts in eyelid reconstruction.

RESUMO

Botulinum toxin prevents acetylcholine release at motor nerve terminals. Group B vitamins (B-vit) are essential for proper nerve function. The present study addresses the question of whether B-vit accelerate recovery in rat skeletal muscle after botulinum toxin A (Btx-A) injection. Forty-four adult male Wistar albino rats were used in this experimental study. Rats were divided into three groups: group 1 rats were given Btx-A injection only, group 2 rats were given B-vit supplementation before Btx-A injection, and group 3 rats were given Btx-A and B-vit injections together. During the experiment, compound muscle action potential (CMAP) of the gastrocnemius muscle was recorded before Btx-A injection and sequentially ten times after toxin injection. The statistical significance of the CMAP amplitude change among the groups was analyzed. All groups showed similar amplitude change between consecutive measurement points. In conclusion, combining Btx-A injection with B-vit supplement does not decrease the efficacy of the toxin.

RESUMO

Venous ulcers are characterised by longstanding and recurrent loss of skin integrity. Once occurred, healing is slow and recurrence is high because of inappropriate conditions of the wound bed. This study involves 20 patients with chronic venous ulcers at least 6 weeks of duration treated with negative pressure wound therapy (NPWT). Patients underwent a radical debridement of all devitalised tissues in the first operation. After adequate haemostasis, silver-impregnated polyurethane foam was applied. Once the wounds were determined to be clean and adequate granulation tissue formation was achieved, split-thickness skin grafts were applied. Black polyurethane foam was applied over them. All wounds completely healed without the need for further debridement or regrafting. The mean number of silver-impregnated foam dressing changes prior to grafting was 2·9 (one to eight changes). The mean number of NPWT foam changes was 2·6 after skin grafting (two to five changes). Two patients who did not use conservative treatments for chronic venous insufficiency (CVI) after discharge from the hospital had recurrence of venous ulcers in the follow-up period. Application of NPWT provides quick wound-bed preparation and complete graft take in venous ulcer treatment.

RESUMO

Background Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy. Studies have shown that results of CTS surgery are poorer in patients with diabetes. In this study, the effect of platelet-rich plasma (PRP) on nerve regeneration was investigated through clinical and electromyographic findings in patients with diabetes who underwent CTS surgery. Methods A retrospective analysis of 20 patients with diabetes who had surgically decompressed CTS was conducted. Patients were divided into two groups. The study group received PRP treatment following surgery. The control group did not receive any treatment. Patients were assessed using electromyography and the Boston Carpal Tunnel Syndrome Questionnaire preoperatively as well as postoperatively at 3-month, 6-month, and 1-year follow-ups visits. Results There was a decrease in complaints and an improvement in sensory and motor examinations in both groups. The Boston Carpal Tunnel Syndrome Questionnaire scores did not show any statistically significant differences between the two groups. However, electromyographic findings showed that there were statistical differences between preoperative and postoperative (3 months, 6 months, and 1 year) results in both groups. When the two groups were compared using preoperative and postoperative (3 months, 6 months, and 1 year) electromyographic values, no statistically significant differences were seen. Conclusion Single injections of PRP did not have a significant impact on median nerve regeneration following CTS surgery in patients with diabetes. The effectiveness of multiple PRP injections can be investigated in patients with diabetes in future studies.

RESUMO

OBJECTIVE: The aim of this study was to investigate the efficacy of angiotensin-converting enzyme inhibitors (ACEIs) in preventing postoperative tendon adhesion formation in a rat model of Achilles tendon repair. METHODS: In this study, 60 Sprague-Dawley male rats weighing 300 to 350 g were used. Rats were randomly divided into six groups (n = 10 per group): control-1, control-2, sham-1, sham-2, experiment-1, and experiment-2. The same surgical procedure was performed in all rats; a full thickness Achilles tenotomy was performed, and the tendon was repaired using a modified Kessler suture. Enalapril (10 mg/kg/day) was orally given to the Experiment-1 and Experiment-2 groups for three and six weeks, respectively. Thirty rats were sacrificed at three weeks (Control-1, Sham-1, Experiment-1); the remaining 30 rats were sacrificed at six weeks (Control-2, Sham-2, Experiment-2). Then, macroscopic, biomechanical, and histologic investigations were performed. RESULTS: Adhesion degree was found macroscopically lower in the Experiment-1 and 2 groups than others. In the histologic examination, the fibrosis level was found the lowest in the Experiment-2 group. Biomechanical evaluation indicated that mean maximum resistance before tendon rupture was significantly higher in the Experiment-2 group than in other groups. CONCLUSION: Evidence from this study has shown that ACEIs can decrease fibrosis and tendon adhesion during tendon recovery in rats due to their antifibrotic effects as the result of Angiotensin-II suppression.

RESUMO

Management of temporomandibular joint (TMJ) disorders presenting with pain, restricted mouth opening, or simply asymptomatic clicking can be challenging even to the experienced surgeon. Many conservative and invasive techniques are available, but most cases can be treated by arthrocentesis of the joint locally. A simple process of joint irrigation enables lysis of intra-articular adhesions, change in the joint viscosity, and clearance of various substances in the joint fluid. Classically, arthrocentesis of the TMJ has been performed with 2 needles: an infusion needle and an aspiration needle. Various devices and techniques have been described in the literature, each with its own benefits and drawbacks. We introduce our technique of TMJ lavage using 2 different gauge needles placed in a concentric manner; hence, besides a less traumatic and easier puncture of the joint capsule, the lavage and aspiration of the joint space can be performed efficiently, with minimal morbidity. The use of a concentric-needle cannula system is the least traumatic and perhaps the most cost-effective method for TMJ lavage described to date. We believe that this technique is applicable and can be performed by even the inexperienced surgeon.
