    Reconstruction of Small and Medium-Sized Nasal Defects Using an Omega Advancement Fla
    (2020) Altun, Serdar; Bal, Ali; Arpaci, Enver; 31895844
    Introduction: The nose is the most common area where malignant skin tumors occur. Repair with a flap after tumor excision provides esthetically and functionally acceptable results. In this study, we aimed to present the use of an omega (omega) advancement flap, which can be applied in all anatomic regions of the nose, in 2 cm or smaller defects. Methods: Between 2015 and 2017, 18 patients underwent repair with omega (omega) advancement flap in the nose after tumor removal. The pathology of 17 patients was basal cell carcinoma, and keratoacanthoma in 1 patient. The average defect diameter was 1.6 x 1.56 cm. The defects were in the nasal tip, nasal wing, lateral nasal wall, and supratip region. After tumors were excised from the safe margin, and were repaired using an omega advancement flap in the same session. Results: No flap necrosis, dehiscence, or infection was observed in the early postoperative period. Three patients developed hematoma under the flap, which was drained. No tumor recurrence was observed during the postoperative follow-up period. The results were satisfactory in all patients. Conclusion: The omega advancement flap is a safe procedure that can be easily applied in the same session for the repair of small-to-medium-sized nasal defects.

    Objective: Two different rat models for degloving injury were described in the literature. Our aim in this study is to compare these rat models to determine which one is more reliable and reproducible. Methods: We surgically induced degloving injury on tails and left hindlimbs of Wistar albino rats (n = 8), and sutured the avulsed tissues back in their original positions after a waiting period. We observed the changes in the avulsed flaps every other day for 10 days. At the end of follow-up period we evaluated the lesions in avulsed flaps by macroscopic measurement of necrosis and histological ulcer scoring using the National Pressure Ulcer Advisory Panel (NPUAP) Scale. Results: The average length of necrosis in avulsed tail flaps was 28.42 +/- 3.04 mm, whereas there was no necrosis in avulsed hindlimb flaps (p < 0.05). The average ulcer score of the lesions in tail and left hindlimb were 3.42 +/- 0.78, and 1.28 +/- 0.48, respectively (p < 0.05). Despite the lack of visible necrosis TUNEL staining revealed an increased amount of apoptotic cells in avulsed hindlimb flaps. Literature review revealed a significant variability in previous studies in terms of the amount of necrosis observed in tail degloving injury model. Conclusion: Tail degloving injury model proved to be a more reliable animal model for degloving injuries. However, standardization of the magnitude of degloving force is required to decrease the variability of necrosis observed in the literature.
