In total, 159 rats were divided into one control and three (primary, secondary, or bilateral pedicle) IP treatment groups. IP was performed on different pedicles by three cycles of 10 minutes of pedicle clamping and 10 minutes of release. After IP procedure secondary pedicle was ligated in all groups, and flaps were exposed to 0, 1, 2, 4, or 6 hours of global ischemia by clamping primary pedicle. In control groups, after the perfusion of bipedicled flaps for 1 hour, left pedicle was ligated and flaps were exposed to global ischemia as in IP groups. On day 5 post-surgery, tissue samples and topographic measurements were taken. No significant differences in semi-quantitative scorings of polymorphonuclear leukocytes infiltration, chronic inflammation, interstitial edema, neovascularization, VEGF, and CD105 expression levels among groups were found (P > 0.05). Percentages of necrosis were consistently smaller in IP groups compared to controls for the same duration of global ischemia, with exception of the no-ischemia. Area of necrosis was significantly smaller in primary IP group versus secondary IP group in the absence of global ischemia (P 0.05). Thus, IP performed on different pedicles may ameliorate flap survival in a comparable fashion, depending on the duration of global ischemia. Secondary pedicle IP was as effective as primary pedicle IP and may be feasible in free flap transfers. (c) 2013 Wiley Periodicals, Inc.

Asymptomatic intradiploic epidermoid cyst has not been reported yet. In this study, incidental diagnosis of asymptomatic cyst and potential impact of that cyst on surgical planning of a patient with craniosynostosis are presented.Publication Metadata only Reconstruction of Internal Nasal Valve, Septum, Dorsum, and Anterior Structures of the Nose in a Single Procedure With a Molded Bone Graft: The Sail Graft(2012-05-01) Guneren, ETHEM; ÇİFTÇİ, Mehmet; KARAALTIN, Mehmet Veli; Yildiz, KEMALETTİN; GÜNEREN, ETHEM; YILDIZ, KEMALETTİNExcessive surgical removal or traumatic loss of the tissues supporting the nasal roof can result in the -saddle nose- deformity. It involves both cartilage and bone deficiencies. Two main resources are used to reconstruct this difficult deformity: autogenous bone and cartilage grafts and alloplastic materials. This study presents the reconstruction of the dorsum, septum, internal nasal valve, and anterior structures and the tip of the nose using a block of molded autogenous bone graft. We called it the -sail graft,- because it looks like a sail from a lateral view. The mast of the sail is oriented in a superior-to-inferior direction, beginning in the frontonasal region to the tip of the nose to form a straight, well-rounded dorsum. The longest postoperative follow-up of 13 cases is now 10 years; the median follow-up is 2 years. The results have been satisfactory.Publication Open Access Pedicled latissimus dorsi myocutaneous flap in the reconstruction of the head and neck region: Experience with 17 patients(2017-07-01) Yildiz, KEMALETTİN; KAYAN, Resit Burak; Guneren, ETHEM; YILDIZ, KEMALETTİN; GÜNEREN, ETHEMObjective: To assess the efficacy of a modified pedicled latis-simus dorsi myocutaneous flap (LDMF) in the reconstruction of defects of the head and neck region. Methods: The retrospective analysis of 17 consecutive patients operated between 2010 and 2014 in the Plastic and Reconstructive Surgery Department of a tertiary care center was performed. Among them, four (23.5%) were initially diagnosed with trauma, while 13 (76.5%) had squamous cell carcinoma originating from the head and neck region. Tumor recurrence, necrosis of the free flap, advanced age, presence of a comorbidity, and previous history of radiotherapy were indicators for a pedicled LDMF. The pedicled LDMF technique was performed via the modified subcutaneous tunnel method in all patients. Demographic, clinical, and peroperative data as well as complications in and a survey of our patients were documented. Results: Our series comprised 11 males (64.7%) and six females (35.3%); the average age was 64.29 +/- 5.43 (range, 51 to 72) years. Seroma (5/17, 29.4%) and partial flap necrosis (3/17, 17.6%) were the most common complications, while the rate of mortality during the follow-up period was 17.6% (3/17). One patient died during the early postoperative period, while two died during their oncological treatment and follow-up. No remarkable functional disabilities or restrictions were postoperatively observed. Conclusion: Our results showed that a pedicled LDMF can constitute a safe and effective alternative for the reconstruction of head and neck defects in selected patients. However, further controlled clinical trials on larger series are warranted to precisely unveil the indications, contraindications, and outcomes of a pedicled LDMF.
