Öğe Acquired Constriction Band Syndrome Affecting Multiple Digits - A Case Report(World Scientific Publ Co Pte Ltd, 2022) Kendir, Munur Selcuk; Dadaci, Mehmet; Uyar, Ilker; Yildirim, Mehmet Emin CemRubber band syndrome is a condition that usually affects children because of wearing a rubber band on the wrist or the ankle. Depending on the degree of pressure caused by the band, patients may present acutely with ischemia and necrosis of the tissues distal to the bands or chronically with change in shape, oedema, loss of function, sensation and rarely amputation. This condition is very rare in adults and most reports in literature are in patients with cognitive impairment or psychiatric illness. We report 62-year-old lady with a background of a psychiatric illness who presented with an acquired constriction band syndrome affecting multiple digits of both hands.Öğe Bilateral Tessier Type 3 CleftRepairment in a Single Session(Thieme Medical Publ Inc, 2018) Uyar, Ilker; Uyar, Sibel Burcak Sahin; Altuntas, Zeynep[Abstract Not Availabe]Öğe A Different Stabilization Technique of Autogenous Cartilage Grafts in Saddle Nose Deformity: Prevention Warping and Resorption(Lippincott Williams & Wilkins, 2019) Gundeslioglu, A. Ozlem; Yildirim, Mehmet Emin Cem; Yarar, Serhat; Uyar, Ilker; Ismayilzade, MajidBackground: Saddle nose deformity (SND) is a collapse of the cartilage and bone structures forming the dorsal projection of the nose. After the use of autologous cartilage in the treatment of SND, resorption and warping continue to be a problem. Methods: This study presents results from 11 patients with SND types III and IV from 2005 to 2017 treated with autologous cartilage fixed with microplates and microscrews. The patients were monitored for at least 1 year. Resorption and warping were measured using postoperative photographs of the patients in the 3rd and 12th months after treatment. Results: No signs of resorption or warping were noted in the patients. Conclusions: Our findings indicate autologous cartilage use with microplates and microscrews is a viable, long-term treatment option for patients with SND types III and IV.Öğe Effect of Vitamin D Deficiency on Hypertrophic Scarring(Lippincott Williams & Wilkins, 2019) Ince, Bilsev; Uyar, Ilker; Dadaci, MehmetBACKGROUND Although many different diseases have been reported with vitamin D deficiency, the authors failed to find any studies on the association of hypertrophic scarring (HS) in the literature. OBJECTIVE The authors aimed to determine the relationship between vitamin D deficiency and HS and investigate the effect of replacement therapy on HS development in patients with vitamin D deficiency. PATIENTS AND METHODS Patients who presented to the authors' outpatient clinic with HS between 2013 and 2016 were included in the study. In the first stage, all the patients with HS complaints were assessed for vitamin D levels. In the second stage, 50 patients with a vitamin D level less than 25 ng/mL and a linear scar after at least 1 year of trauma were randomly divided into 3 groups. Group 1: patients who did not accept any medical or surgical treatment; Group 2: patients who were subjected to vitamin D replacement only; Group 3: patients who underwent surgical excision and suturation after vitamin D replacement. RESULTS A statistically significant correlation was found between HS and vitamin D levels (p < .05). A statistically significant decrease in scar width was observed in Group 3 (p < .05). CONCLUSION Increasing vitamin D levels to above 25 ng/mL before scar revision and vitamin D deficiency in patients with HS may help reduce scar width.Öğe The effects of a combination treatment with mesenchymal stem cell and platelet-rich plasma on tendon healing: an experimental study(Tubitak Scientific & Technological Research Council Turkey, 2022) Uyar, Ilker; Altuntas, Zeynep; Findik, Siddika; Yildirim, Mehmet Emin Cem; Yarar, Serhat; Aktan, Murat; Avci, AlunetBackground/Aim: The objective of this study was to investigate the effects that the application of mesenchymal stem cells (MSCs) and platelet-rich plasma (PRP) following tendon repair have on the strength and healing of the tendon and also to examine the possible mechanisms of action that take place. Materials and methods: The Achilles tendons of 80 rats were repaired and divided into eight groups. Following the repairs, MSCs obtained from humans were injected into the rat tendons in groups 1 and 2, a combination of MSCs from humans and PRP from rats was injected into the tendons in groups 3 and 4, and PRP from rats was injected into the tendons in groups 5 and 6. These procedures all took place simultaneously. Groups 7 and 8 did not receive any injections following the repairs. The rats were sacrificed at the end of the first and second months following the procedures, and biomechanical and histopathological analyses were performed. Results: Inflammatory cell density increased most significantly in the combined group when compared to the first and second months. The fibroblast density on the tendon repair region was significantly lower in the second-months groups of each intervention compared to their first-month groups (p = 0.001). For the analysis of the maximum tensile breaking force, the behaviors of the groups over time were significant when compared to the control groups (p = 0.0015). Also, the mean maximum breaking force in the combined group was statistically significantly higher at the end of the second month than at the end of the first month (p = 0.0008). Conclusion: The combination therapy increased tendon strength force. This combination therapy can make a positive contribution to the healing of tendons after surgery.Öğe Evaluation of the effectiveness of the tuba uterina tubular flap in the peripheral nervous system regeneration in rats(Taylor & Francis Ltd, 2022) Yildirim, Mehmet Emin Cem; Dadaci, Mehmet; Ince, Bilsev; Uyar, Ilker; Yarar, Serhat; Oltulu, Pembe; Aygul, RecepNerve conduits could be used to provide a bridge between both nerve endings. In this study, the tuba uterina of female rats were prepared in a vascularized pedicled flap model and it used as a nerve conduit. The aim was to investigate the effectiveness of a vascularized pedicle nerve conduit and its ciliated epithelium in a sciatic nerve defect. The study was conducted between May and August 2018, and used a total of 60, 14-16-week-old female Wistar albino rats. Six groups were created; Cut and Unrepaired Group, Nerve Graft Group, Flap-Forward Group (Tuba uterina tubular flap, forward direction), Flap-Reversed Group (Tuba uterina tubular flap, reverse direction), Graft-Forward Group (Tuba uterina tubular graft, forward direction) and Graft-Reverse Group (Tuba uterina tubuler graft, reverse direction). Nerve regeneration was evaluated 3 months (90 days) after the surgery by the following methods: (1) Sciatic Functional Index (SFI) measurement, (2) Electromyographic (EMG) assessment, (3) Microscopic assessment with the light microscope and (4) Microscopic assessment with the electron microscope. According to the SFI, EMG and microscopic assessments with the light and electron microscope, it was observed that the transfer of tuba uterina tubular conduit as a graft was statistically better in its effect on nerve regeneration than flap transfer, but also indicated that the direction of the ciliated structures had no significant effect. We believe that as this model is improved with future studies, it will shed light on new models, ideas and innovations about nerve conduits.Öğe Facilitating triple rhomboid flaps for meningomyelocele defect closure using a honeycomb structure as a template(Springer, 2016) Karacor-Altuntas, Zeynep; Dadaci, Mehmet; Erdi, Fatih; Ince, Bilsev; Uyar, Ilker; Yarar, SerhatPurpose Various reconstruction options are available for the soft-tissue coverage of meningomyelocele defects. For small defects, primary closure or local single flaps may be sufficient, while large defects require more complex reconstructive techniques. This study suggests an easy way for surgeons to close large meningomyelocele defects using triple rhomboid flaps. Methods The hexagonal structure of a honeycomb was considered when planning for the coverage of large meningomyelocele defects. The intact skin around the defect was imagined as multiple hexagons, which allowed us to plan triple rhomboid flaps correctly and more easily. This technique was used in seven patients with defects ranging from 7 x 5 to 12 x 8 cm in size. Results No major postoperative complications were seen. Minimal dehiscence was observed in two patients and healed secondarily. Conclusions The honeycomb modification for planning triple rhomboid flaps is an easy, practical, and memorable approach for surgeons reconstructing large meningomyelocele defects.Öğe Histopathological evaluation of the effect of hyperbaric oxygen therapy on capsule occurrence around silicone breast prosthesis: an experimental study(Taylor & Francis Ltd, 2021) Yarar, Serhat; Arslan, Abdullah; Ince, Bilsev; Yildirim, Mehmet Emin Cem; Oltulu, Pembe; Uyar, Ilker; Dadaci, MehmetBackground In general, capsular contracture is the underlying cause of complications such as pain, stiffening, breast asymmetry, and animation deformity that are seen in the late postoperative period due to the use of silicone breast prostheses. Considering the positive effects of HBO therapy on wound healing, the objective of this study was to investigate the effect of HBO therapy on capsule reaction occurring due to silicone implants. Material and Methods Rats were divided into four groups. 1 cm x 1 cm silicone implants with rough surface were inserted in subcutaneous plane on the m spinotrapezius muscle fascia at just right of the dorsal region midline in rats in Group 1, while implants with same properties were inserted beneath m spinotrapezius muscle in rats in Group 2. Implants with the same properties were inserted in the subcutaneous area on the m spinotrapezius muscle in rats in Group 3 and into the area under the muscle in rats in Group 4. Beginning from the first postoperative day, rats in Groups 3 and 4 received HBO therapy for 90 min under 2.5 ATM pressure as one session a day over 15 days. Results The mean capsule thickness was statistically significantly lower in the groups treated with HBO compared to the control groups. Fibroblast, neutrophil and macrophage counts were statistically significantly lower in the groups treated with HBO compared to the control groups. Conclusion We believe that HBO therapy can be used as an adjuvant treatment options to decrease capsule contraction occurring after silicone implant application.Öğe Our Clinical Experiences in Lower Eyelid Reconstruction(Wolters Kluwer Medknow Publications, 2018) Altuntas, Zeynep; Uyar, Ilker; Findik, SidikaObjective: Different treatment principles have been applied in the reconstruction of partial or full layer defects of the lower eyelid. The use of the most similar tissue for eyelid reconstruction is important for both functional and esthetic results. This study aims to investigate the reconstruction methods performed in lower eyelid defects and to evaluate their esthetic and functional results. Patients and Methods: In this study, patients who underwent reconstructive surgery from 2012 to 2016 in our clinic were investigated. Cases of primary repairs after skin tumors located in the lower eyelids were excluded from the study. The sociodemographic characteristics of patients, the type and location of the tumor, defect size after surgery, anterior and posterior lamellar defects, and reconstruction methods used were retrospectively reviewed. Results: Thirty-seven patients were included in the study. Fifteen were male and 22 were female. There was only anterior lamellar defect in 29 patients and full-thickness lower eyelid defect in 8 patients. Anterior flaps used in lamellar defects were identified as glabellar flap, Limberg flap, advancement, transposition flap, nasolabial flap, forehead flap, and cheek flap. Chondromucosal graft, palatal mucosal graft, and buccal mucosal graft were used for repairing posterior lamellar defects. Conclusion: Separate reconstruction of the posterior and anterior lamellae is important to provide good functional and esthetic results in lower eyelid reconstruction. Depending on the size of the defect, using a single local flap or a combined flap with posterior lamella repair provides highly acceptable results.Öğe A Rare Case: Primary Venous Malformation in Parietal Bone(Karger, 2021) Yarar, Serhat; Uyar, Ilker; Yildirim, Mehmet Emin Cem; Dadaci, Mehmet; Ince, BilsevPrimary intraosseous vascular malformations (PIVMs) are rare intraosseous lesions, accounting for approximately 0.5-1% of all intraosseous tumours. In this case report, we aimed to present a rare case of intraosseous vascular malformation causing a large lytic area in the parietal bone. A 25-year-old male patient was admitted to the clinic with a mass on the parietal bone. On physical examination, it was observed that the hair density on the mass was decreased, the mass had a soft consistency, and there was no pain on palpation. The patient was operated under local anaesthesia with a provisional diagnosis of a trichilemmal cyst. However, intraoperative diagnosis was a vascular malformation. There was a 3-cm full-thickness defect on the parietal bone caused by the lesion. The mass was excised completely while preserving the integrity of the dura. The resulting defect was reconstructed with bilateral rotation advancement flaps. The calvarial defect was not reconstructed due to equipment inadequacy. No complications were encountered in the postoperative period. Ninety-three PIVM cases have been reported in the skull since 1845. In very few of these cases, the mass is located in the parietal bone. The pathogenesis of PIVMs is not completely understood. The definitive diagnosis is made by histopathological examination. The therapeutic gold standard is surgery. Surgeons should keep in mind that radiological examination before the operation could prevent undesirable complications.Öğe A Rare Congenital Case: Aplasia Cutis Congenita(Thieme Medical Publ Inc, 2021) Uyar, Ilker; Sahin Uyar, Sibel Burcak; Cem Yildirim, Mehmet Emin; Yarar, Serhat; Dadaci, Mehmet[Abstract Not Availabe]Öğe A Rare Congenital Facial Abnormality: Complete Arhinia(Thieme Medical Publ Inc, 2021) Altuntas, Zeynep; Uyar, Ilker; Yildirim, Mehmet Emin Cem[Abstract Not Availabe]Öğe Scrotal Fasciocutaneous Flap for the Reconstruction of the Pubic Region After a High-voltage Electrical Burn(Medknow Publications & Media Pvt Ltd, 2016) Altuntas, Zeynep; Uyar, Ilker; Dadaci, Mehmet; Ince, Bilsev; Yavuz, Nurten; Gundeslioglu, A.
