Repair of circular scar in the forearm by expanded double-pedicle omega-shaped flap at the rear flank of bottom-waist / 中华整形外科杂志

<p><b>OBJECTIVE</b>To discuss the method for repairing the circular scar in the forearm.</p><p><b>METHODS</b>Large expander (400-600 ml) were implanted subcutaneously at the rear flank of bottom-waist in the way of overlapping or continued expansion. After expansion was completed, the horizontal opened omega-shaped flap was formed by advancement of expanded skin with the two pedicles at the two sides. Then the forearm was tunneled under flap with the wound covered by flap. The pedicles were cut off at the third stage.</p><p><b>RESULTS</b>From April 1998 to June 2009, 8 cases were treated with no flap necrosis. The patients were followed up for 1 to 3 years with good flap color and thickness. Flap sensory was partially recovered. Linear atrophic scar was left in the donor sites.</p><p><b>CONCLUSIONS</b>It is feasible to repair forearm circular scar by expanded double-pedicle omega-shaped flap at the rear flank of bottom-waist.</p>

Reconstruction of skin defect at frontal hair line with mastoid fasciocutaneous island flap / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the reconstruction of skin defect at frontal and temporal hair line.</p><p><b>METHODS</b>5 cases with skin defect at frontal and temporal hair line were treated with mastoid fasciocutaneous island flap pedicled with parietal branch of superficial temporal artery.</p><p><b>RESULTS</b>All the flaps survived completely. Hair grew up 5 - 7 days after operation, showing good reconstructed hair line.</p><p><b>CONCLUSIONS</b>Mastoid fasciocutaneous island flap is a reliable method for reconstruction of skin defect at frontal and temporal hair line.</p>

Clinical application of sural neurocutaneous island flaps / 中华整形外科杂志

<p><b>OBJECTIVE</b>To explore the clinical application characteristics of sural neurocutaneous island flaps.</p><p><b>METHODS</b>Sural neurocutaneous island flaps were used to repair the skin defect accompanied bone and tendon exposure in the lower leg, around the ankle and foot in 21 cases, including 4 cases to repair the foreside of the foot back . Direct flap was used in 5 cases and reverse flap in 16 cases. Meanwhile the coverage and formation of sural nerve were surveyed together with the starting point of peroneal perforator.</p><p><b>RESULTS</b>All the 21 sural flaps were survived, including sural nerve (18 cases) anastomose 12 cases, single trunk 4 cases, double trunk 2 cases. The anastomose site of medial sural cutaneous nerve and the communicating branch of lateral sural cutaneous nerve was at the point of 11 - 14 cm above the ankle in 12 cases. The lower was the anastomose site, the shorter was the sural nerve. The site is 4 - 7 cm above the ankle in 15 out of 18 sural nerve perforator branch cases, and the other 3 cases is 10, 11, 11.5 cm above the ankle respectively.</p><p><b>CONCLUSIONS</b>Sural neurocutaneous island flaps are easy to separate. Major arteries are not injured. It is the ideal flap to repair the skin defect accompanied by bone and tendon exposure in lower leg, around ankle and foot. The nerve must be anastomosed when repairing the heel.</p>

The expanded cross-leg flap for repairing the soft tissue defects of the instep / 中华整形外科杂志

<p><b>OBJECTIVE</b>To explore the clinical application of the expanded cross-leg flap for repairing instep soft tissue defects with bone exposure.</p><p><b>METHODS</b>The expanded cross-leg flap was used to repair instep defects in 10 patients. After flap transferring the donor site was closed directly without skin grafting.</p><p><b>RESULTS</b>Satisfactory results were achieved in all the cases. The flaps survived well. The donor site had less scar and kept good appearance.</p><p><b>CONCLUSIONS</b>The expanded cross-leg flap is a better choice for repairing the soft tissue defects of the instep. It is simple and easy with less trauma to the donor site. After the operation, both the recipient and the donor areas had good appearance.</p>
