ObjectiveTo evaluate the effectiveness of double pedicled flap and technique of geometric broken line (GBL) for primary repair of serious dog bite wound. MethodsBetween October 2006 and December 2014, 9 patients with serious dog bite wound were treated. There were 3 males and 6 females with an average age of 34.5 years (range, 8-68 years), and with a mean disease duration of 4 hours (range, 30 minutes to 24 hours). The defect ranged from 1.7 cm×0.5 cm to 15.0 cm×8.0 cm, with the mean depth of 0.5 cm (range, 0.3-0.8 cm). Deep tissue exposure was observed. After routine debridement, a vacuum sealing drainage (VSD) was equipped to suck and irrigate for 1 day, then wound was repaired. The superomedial edge of defect was trimmed, then a GBL shape mainly with square and rectangular was designed. According to defect size, a double pedicled flap was designed at the lateroinferior edge of defect, which size ranged from 1.7 cm×1.5 cm to 18.0 cm×15.0 cm. The donor site was sutured directly. VSD was used for 3 days after operation. ResultsAll flaps survived and wound healed, and donor site incision healed well, with invisible scar. All patients were followed up 6 months to 8 years (mean, 4 years). The wounds were repaired well, and the patients had good facial appearance. No rabies attack was observed during follow-up. ConclusionIt is an ideal repair method to chose double pedicled flap and technique of GBL for primary repair of dog bite wounds. Satisfactory cosmetic appearance can be obtained.
