BACKGROUND Early identification of failing free flaps may allow for potential intervention and flap salvage. The predictive ability of flap temperature monitoring has been previously questioned. The present study investigated the ability of an infrared surface temperature monitoring device to detect trends in flap temperature and correlation with anastomotic thrombosis and flap failure. METHO...

BACKGROUND The extended deep inferior epigastric perforator (DIEP) artery flap had been described in 1983. For head and neck reconstruction, we have been using a variation of this flap, namely a perforator free flap of the deep inferior epigastric system with a superolateral extension of the skin paddle. METHODS The purpose of this study was to present our 10-year experience in the performanc...

The flap endonuclease gene homologue from the hyperthermophilic archaeon, Pyrococcus horikoshii, was overexpressed in Escherichia coli and purified. The results of gel filtration indicated that this protein was a 41-kDa monomer. P. horikoshii flap endonuclease (phFEN) cleaves replication fork-like substrates (RF) and 5' double-strand flap structures (DF) using both flap endonuclease and 5'-3'-e...

A computational study of a generic wing with a half span flap shows the mean flow effects of several blown flap configurations. The effort compares and contrasts the thin-layer, Reynolds averaged, Navier-Stokes solutions of a baseline wing-flap configuration with configurations that have blowing normal to the flap surface through small slits near the flap side edge. Vorticity contours reveal a ...

RATIONALE A 54-year-old Taiwanese male came to our hospital presented with right retromolar mucoepidermoid carcinoma. Composite resection and right modified radical neck dissection were performed. We then use free anteral lateral thigh flap to reconstruct the defect. However, venous congestion was found 32 h after the surgery. PATIENT CONCERNS The main concerns of the patient is complete salv...

An anterolateral thigh flap was salvaged using 110 medical leeches in the absence of an available vein for reanastomosis. After surgical construction of the flap for full-thickness thoracic wall reconstruction, the patient developed complete venous occlusion. Specifically, the anastomotic vein developed complete occlusion, and the internal jugular vein had a thrombus. In addition, because the l...

OBJECTIVE To investigate the effects on overall flap dynamics of altering the length of the primary flap in the Zitelli bilobed flap procedure, because the standard Zitelli design can result in distortion of the alar margin after repair of cutaneous nasal alar defects. METHODS Identical 1.5-cm circular cutaneous defects were made on the nasal alae and cheeks of 6 fresh human cadavers. A recta...

INTRODUCTION The anterolateral thigh perforator flap (ALT) represents the workhorse for most reconstructive efforts in the head and neck regions. The main advantages of this flap are its versatility, the length of the pedicle, and the low morbidity of the donor site. The major drawback is the bulkiness of this flap with the frequent need for secondary revisions. To overcome this, we have develo...

A groin flap is an axial-patterned cutaneous flap based on the superficial circumflex iliac arteriovenous system, which can provide soft-tissue coverage to defects on any aspect of the hand and the distal two thirds of the forearm. One of the presumed disadvantages of the pedicled groin flap is the discomfort experienced by the patient during the time required before flap division. These disadv...

The pressure ulcer of the ischial region is often accompanied by complete paraplegia in patients with spinal cord injury and is attributable to the compression and breakdown of tissue arising from constant sitting. Characteristically, a pressure ulcer of this region is circular and deep. We recently reconstructed ischial decubitus ulcer of 8 patients using simple-designed bilobed flap. In all c...
