BACKGROUND: After @entity2419 repair, oronasal @entity292 (ONF) formation is one of the considerable and troublesome complications. Conchal cartilage graft is one option that can be used in recurrent @entity292 correction. The aim of the current study is investigating the recurrence rate of the hard palate ONF or ONF at the junction of hard and soft palate after utilizing conchal cartilage graft and comparing this rate with other methods. MATERIALS AND METHODS: In this observational prospective study, 29 @entity1 suffering from ONF with small, medium and large sizes who were referring to Alzahra university hospital, Isfahan, Iran and Fateme Zahra university hospital, Tehran, Iran between November 2011 and November 2012 were enrolled. All @entity1 had midline @entity2419 , 29.6% of them had @entity3384 too that was repaired previously. All @entity1 were followed-up for 2 years (every 2 months) after repair. RESULTS: The mean (range) age of studied samples was 10.7 (2-23) years. 16 @entity1 (55.7%) were female, and reminders were male. During 2 years followup, we detected recurrence of ONF in 6 @entity1 (20.68%) and the success rate was 79.32%. The recurrence rate, after applying the current approach, among who experienced the several times of recurrence was significantly higher than among those who experienced first time of recurrence (33.3% vs. 7.1%; P < 0.001). The mean [  SD] age of failed and successfully repaired @entity1 were 11.3 (  4.5) and 8.4 (  5.25) years, respectively (P > 0.1). CONCLUSION: Using of conchal cartilage graft for recurrent ONF with  <=1 cm was safe and efficacious, in ONF >1 cm conchal cartilage graft can be used as a primary method and if recurrence occurred chooses other complex procedure.
