Reconstruction of palatal defect using mucoperiosteal hinge flap and pushback palatoplasty.
This article describes a simple, new surgical technique to provide a complete two-layer closure of palatal defect resulting from a surgical complication of trans palatal resection of skull base chordoma. The nasal layer was reconstructed with triangular shape oral mucoperiosteal turn over hinge flap based on anterior margin of palatal defect and rectangular shaped lateral nasal mucosal hinge flaps. The oral layer was reconstructed with conventional pushback V-Y advancement 2-flaps palatoplasty. Each layer of the flaps were secured with two key mattress suture for flap coaptation. This technique has some advantages: simple, short operation time, one-stage procedure, no need of osteotomy. It can close small- to medium-sized palatal defect of palate or wide cleft palate and can prevent common complication of oronasal fistula, which could be caused by tension.
