<br/><br/> Recurrence rates of fistula after its repair is higher, described as 25-33% up to 100%. Fistulas are classified by their site and size. According to site: commonest site is the hard palate & junction between hard & soft palate. Other sites are: soft palate, uvula, and junction between primary & secondary palate. According to size, Cohen et al. classified fistulas into small (1-2mm), medium (3-5mm) & large (>5mm) in diameter. Occurrence of fistula formation depends on type of primary defect and type of primary repair (occurs more frequently with Wardill-Kilner type) Palatal fistula is repaired using local mucoperiosteal flaps, after primary repair of the fistula, if failed this increases the risk of occurrence of the fistula due to fibrosis & decreased vascularization that occur with each surgery
