PURPOSE To evaluate programmed versus achieved laser-assisted in situ keratomileusis (LASIK) flap central thickness and investigate topographic flap thickness variability, as well as the effect of potential epithelial remodeling interference on flap thickness variability. PATIENTS AND METHODS Flap thickness was investigated in 110 eyes that had had bilateral myopic LASIK several years ago (av...
introduction: reconstruction of intraoral soft tissue defects is important in restoring function and esthetic. in large defects, there will be demand for regional pedicle flaps or free flaps. hard palate separates nasal and oral cavities. due to the small surface area between flap and remaining palate after surgical resections, optimal blood supply of the flaps for hard palate reconstructions a...
We performed a new procedure for reconstruction of donor site of a deltopectoral (DP) flap. A 58-year-old man presented with a wide subcutaneous abscess, which was caused by acute mandibular osteomyelitis due to dental caries. On admission, the patient received a neck incision for drainage. However, necrosis of the neck skin was observed after drainage. The patient had an 8 × 10 cm skin and sof...
Background: Reconstruction by free tissue transfer and microvascular anastomosis can provide a reliable repair for tissue defects in head and neck surgeries. During this study, we evaluated the clinical characteristics and outcomes of reconstructive surgery by the use of free flaps for defects resulting from head and neck cancers. Methods: This quasi-experimental study included 29 patients ha...
Abstract Background: The retroauricular-temporal or Washio flap has been introduced for reconstruction of partial nose and cheek defects, and has many advantages. We decided to evaluate the extended use of this technique in order to repair full thickness nasal defects. Methods: Superficial temporal and retroauricular arteries are identified with Doppler flowmetry. Selection points A, B, C and ...
BACKGROUND Studies have focused on enhancing flap viability using superoxide dismutase (SOD), but only a few used SOD from human origin, and most gave the compound systemically. We evaluated the ability of SOD to improve random skin flap survival using human recombinant copper-zinc superoxide dismutase (Hr-CuZnSOD) in variable doses, injected intradermally into the flap. METHODS Seventy male ...
Vascularized periosteal flaps are used for complex cases if the reconstruction of large bone defects is necessary in modern trauma and orthopedic surgery. In this study, we combined this surgical procedure with β‑TCP scaffold and mesenchymal stem cells (MSCs) + endothelial progenitor cells (EPCs) as a tissue engineering approach to obtain optimum conditions for bone healing in rats. A critical ...
BACKGROUND The facial artery myomucosal (FAMM) island flap is a cheek flap, pedicled on the facial artery and suitable for small to medium-sized reconstructions of the oral cavity and neighboring areas. A novel transposition of the flap to the hypopharynx after laryngectomy is presented in this report. METHODS A 58-year-old man, previously irradiated, was laryngopharyngectomized because of a ...
Tumor resection causes damage in the head and neck which creates problems in swallowing, chewing, articulation, and vision, all of which seriously affect patients' quality of life. In this work, we evaluated the application of a free medial tibial flap in reconstruction of head and neck defects after tumor resection. We discussed the anatomy, surgical technique, and the advantages and disadvant...
Due to the significant morbidity and mortality associated with pharyngocutaneous fistula in pharyngoesophageal reconstruction following cancer resection, the purpose of this retrospective study is to examine the selection of tubed skin flaps that impact anastomotic integrity. The flaps evaluated included radial forearm flap versus anterolateral thigh flap, and fasciocutaneous anterolateral thig...
