Öğe Assessment of Patients Who Underwent Nasal Reconstruction After Non-Melanoma Skin Cancer Excision(Lippincott Williams & Wilkins, 2015) Uzun, Hakan; Bitik, Ozan; Kamburoglu, Haldun Onuralp; Dadaci, Mehmet; Calis, Mert; Ocal, EnginBackground: Basal and squamous cell carcinomas are the most common malignant cutaneous lesions affecting the nose. With the rising incidence of skin cancers, plastic surgeons increasingly face nasal reconstruction challenges. Although multiple options exist, optimal results are obtained when like is used to repair like''. We aimed to introduce a simple algorithm for the reconstruction of nasal defects with local flaps, realizing that there is always more than one option for reconstruction. Patients and Methods: We retrospectively reviewed 163 patients who underwent nasal reconstruction after excision of non-melanoma skin cancer between March 2011 and April 2014. We analyzed the location of the defects and correlated them with the techniques used to reconstruct them. Results: There were 66 males and 97 females (age, 21-98 years). Basal cell carcinoma was diagnosed in 121 patients and squamous cell carcinoma in 42. After tumor excision, all the defects were immediately closed by either primary closure or local flap options such as Limberg, Miter, glabellar, bilobed, nasolabial, V-Y advancement, and forehead flaps. Conclusions: Obtaining tumor-free borders and a pleasing aesthetic result are major concerns in nasal reconstruction. Defect reconstruction and cosmesis are as important as rapid recovery and quick return to normal daily activities, and these should be considered before performing any procedure, particularly in elderly patients.Öğe Assessment of survival rates compared according to the Tamai and Yamano classifications in fingertip replantations(Medknow Publications & Media Pvt Ltd, 2016) Dadaci, Mehmet; Ince, Bilsev; Altuntas, Zeynep; Bitik, Ozan; Kamburoglu, Haldun Onuralp; Uzun, HakanBackground: The fingertip is the most frequently injured and amputated segment of the hand. There are controversies about defining clear indications for microsurgical replantation. Many classification systems have been proposed to solve this problem. No previous study has simultaneously correlated different classification systems with replant survival rate. The aim of the study is to compare the outcomes of fingertip replantations according to Tamai and Yamano classifications. Materials and Methods: 34 consecutive patients who underwent fingertip replantation between 2007 and 2014 were retrospectively reviewed with respect to the Tamai and Yamano classifications. The medical charts from record room were reviewed. The mean age of the patients was 36.2 years. There were 30 men and 4 women. All the injuries were complete amputations. Of the 34 fingertip amputations, 19 were in Tamai zone 2 and 15 were in Tamai zone 1. When all the amputations were grouped in reference to the Yamano classification, 6 were type 1 guillotine, 8 were type 2 crush and 20 were type 3 crush avulsions. Results: Of the 34 fingertips, 26 (76.4%) survived. Ten (66.6%) of 15 digits replanted in Tamai zone 1 and 16 (84.2%) of 19 digits replanted in Tamai zone 2 survived. There were no replantation failures in Yamano type 1 injuries (100%) and only two failed in Yamano type 2 (75%). Replantation was successful in 14 of 20 Yamano type 3 injuries, but six failed (70%). The percentage of success rates was the least in the hybridized groups of Tamai zone 1-Yamano type 2 and Tamai zone 1-Yamano type 3. Although clinically distinct, the survival rates between the groups were not statistically significantly different. Conclusions: The level and mechanism of injury play a decisive role in the success of fingertip replantation. Success rate increases in proximal fingertip amputations without crush injury.Öğe Groin and thigh reconstructions with pedicled rectus abdominis myocutaneous flaps(Tubitak Scientific & Technological Research Council Turkey, 2017) Uzun, Hakan; Bitik, Ozan; Baltu, Yahya; Dadaci, Mehmet; Kayikcioglu, Aycan UgurBackground/aim: Resection of tumors from the groin and thigh regions with safe margins often results in significant soft tissue defects, which preclude primary closure. This study presents a series of rectus abdominis myocutaneous flaps for irradiated thigh and groin wounds with the purpose of evaluating the efficacy and outcomes of these flaps in this population. Materials and methods: From 2008 to 2015, all patients who underwent resection of thigh or groin region tumors and reconstruction with an inferiorly based rectus abdominis myocutaneous flap were retrospectively identified. Medical records of the patients were reviewed. Results: A total of 27 patients, aged 20-67 years, were operated on for defects in the groin and upper thigh region. Nine patients underwent immediate reconstruction. The remaining 18 patients underwent late reconstruction. There was neither total flap loss nor partial flap loss. We chose to utilize 15 ipsilateral and 12 contralateral pedicles. The mean length of stay in hospital was 13.7 days. Conclusion: A rectus abdominis myocutaneous flap can be successfully used in patients with groin and upper thigh defects due to its predictable and robust vascular supply, bulky muscle content, wide arc of rotation, and large skin island.Öğe Groin and thigh reconstructions with pedicled rectus abdominis myocutaneous flaps(2017) Uzun, Hakan; Bitik, Ozan; Baltu, Yahya; Dadacı, Mehmet; Kayıkçıoğlu, Aycan UğurBackground/aim: Resection of tumors from the groin and thigh regions with safe margins often results in significant soft tissue defects, which preclude primary closure.

Accordingly, the anterior septal extension technique has proven itself to be a powerful tool for achieving long-lasting nasal tip projection in rhinoplasty. However, anterior septal extension does not protect against postoperative loss of nasal tip rotation unless an additional suspension strategy is used. A tip-suspending transfixion suture is the authors' strategy for supporting nasal tip rotation whenever an anterior septal extension technique is performed. Of 156 rhinoplasties performed by the authors between 2010 and 2012, a cohort of 22 droopy-tip rhinoplasties was extracted in which the described technique was used. The patients in this cohort were included in a retrospective nasal tip projection and rotation analysis. The nasolabial angle (NLA) and Goode ratio measurements were compared between preoperative, 3-week postoperative, and 1-year postoperative profile-view photographs. The NLA and the Goode ratio measurements were significantly higher in the 3-week postoperative group than in the preoperative group, indicating an effective gain in both tip projection and rotation. The NLA and the Goode ratio measurements did not differ statistically between the postoperative 3-week and postoperative 1-year groups, indicating long-term maintenance of nasal tip position. A tip-suspending transfixion suture is an easy method for securing nasal tip rotation when used in conjunction with an anterior septal extension.

The purpose of this study is to describe a new technique of interposition vein graft guided by polypropylene suture in distal fingertip replantation. Methods: A total of eight consecutive Tamai zone 1 fingertip replantations performed by the same author were included. All replantations were performed using interposition vein graft guided by polypropylene suture. This technique involved a vein graft of similar to 2 cm, with appropriate calibration, obtained from the volar part of the forearm and a 2-0 polyprolene suture passed through the interposition vein graft. Then, a polypropylene suture guide carrying the vein graft was inserted into the artery. The anastomosis was easily performed with the aid of 10-0 or 11-0 nylon in a bloodless medium and without encountering the posterior wall problem. Results: Average surgery time was 2.5 hours (range = 2-3 hours). Among eight Tamai zone 1 replantations, six were successful (75%). There were two replantations lost because of arterial failure. Conclusion: This technique may ease fingertip replantations and increase the success rate for Tamai zone 1 injuries.
