In recent developments in the repair of large surgical defects where simple flap rotation may have been previously employed, myocutaneous flaps are being used because of functional advantages and to decrease the number of reconstructive procedures. The authors have employed myocutaneous flaps in 40 cases from January 1980 until April 1985 at Presbyterian Medical Center in Chonju. The primary di...

In 1952, Bjork created an inferior based tracheal flap through 2nd, 3rd and 4th tracheal ring which was later fixed to skin to secure the lumen of a tracheotomy tube. [1] Following this Bjork flap, many studies came which cited various complications or drawbacks for this flap. However, various studies have also reported no added risk and absence of complications associated with this. A recent g...

Okazaki fragments are initiated by short RNA/DNA primers, which are displaced into flap intermediates for processing. Flap endonuclease 1 (FEN1) and Dna2 are responsible for flap cleavage. Replication protein A (RPA)-bound flaps inhibit cleavage by FEN1 but stimulate Dna2, requiring that Dna2 cleaves prior to FEN1. Upon cleavage, Dna2 leaves a short flap, which is then cut by FEN1 forming a nic...

OBJECTIVES/HYPOTHESIS To describe a modification of the originally described superiorly based pharyngeal flap as a secondary operation to correct velopharyngeal insufficiency (VPI) in patients with nonsyndromic repaired cleft palate. STUDY DESIGN Prospective clinical trial at university medical center. METHODS Twenty-six patients with VPI after cleft palate repair underwent a modified poste...

OBJECTIVE Sacrococcygeal pilonidal sinus is common in young men and may recur over time after surgery. We investigated whether a factor exists that can aid in the determination of the preferred technique between the early Limberg flap and Karydakis flap techniques for treating recurrent pilonidal sinus. MATERIALS AND METHODS This prospective and randomized study enrolled 71 patients with recu...

BACKGROUND Breast reconstruction with deep inferior epigastric perforator (DIEP) flaps has gained considerable popularity due to reduced donor-site morbidity. Previous studies have identified the superficial venous system as the dominant outflow to DIEP flaps. DIEP flap venous congestion occurs if superficial venous outflow via the deep venous system is insufficient for effective flap drainage....

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...
