Cephalic de-mucosalized superiorly-based pharyngeal flap: A modified mucosa-preserving technique for velopharyngeal insufficiency

The modified technique provides an immediate self-mucosa cover to the superior part of the posterior pharyngeal wall, thus it could promote primary healing at the donor site with a short period of convalescence. CDPF separates the two opposing raw surfaces of the flap and the posterior pharyngeal wall. The mucosal flap might guard against downward migration of the flap.
