Objection To explore the application of prefabricated superficial temporal fascia postauricular flap in the repair of huge facial defect. Methods From 2007, 10 cases with huge facial defects were treated with prefabricated superficial temporal fascia postaurieular flap. Pedicled superficial temporal fascia flap was prefabricated under postaurieular skin with the tissue expander implanted simultaneously. After 3-5 months of skin expansion, the distribution of the new branches of prefabricated superficial temporal artery were observed by DSA. Then the tissue expander was removed and the islanded postauricular flap pedicled with superficial temporal artery was formed to repair the facial skin defect through tunnel. Results All the patients were followed up for 6 months to 1.5 years. Epidermis necrosis caused by the problem of venous return were observed in 2 cases and were recovered within 2 weeks. The other flaps were all survived. The largest area of flap was 7 cm×3.5 cm. The patients were all satisfied. Conclusion The prefabricated superficial temporal fascia postauricular flap is effective in the repair of huge facial defect with its thinner texture, enough tissue and no additional scar at face.
