Abstract
A double layer repair of palatal fistulae offers the best chance of success for their closure. Two local factors act against attaining this desired purpose. They are as follows: a) the unyielding, firm, relatively immobile mucous membrane of the hard palate, which does not lend itself to the usual rotation flap technique; b) the shortage of nasal mucous membrane, which severely limits the degree to which this layer can be mobilized. The negative features of these two factors are further accentuated following injury and palatal surgery, because scarring further restricts mobilization and rotation of local tissues (1).
