Recurrence rate of repaired hard palate oronasal fistula with conchal cartilage graft

Abstract

Background: After cleft palate repair, oronasal fi stula (ONF) formation is one of the considerable and troublesome
complications. Conchal cartilage graft is one option that can be used in recurrent fi stula 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 patients suff ering from ONF with small, medium and large sizes who were referring to Alzahra university hospital, Isfahan, Iran and FatemeZahra university hospital, Tehran, Iran between November 2011 and November 2012 were enrolled. All patients had midline cleft palate, 29.6% of them had cleft lip too that was repaired previously. All patients 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 patients (55.7%) were female, and reminders were male. During 2 years followup, we detected recurrence of ONF in 6 patients (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 signifi cantly higher than among those who experienced fi rst time of recurrence (33.3% vs. 7.1%; P < 0.001). Th e mean [±SD] age of failed and successfully repaired
patients 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 effi cacious, in ONF >1 cm conchal cartilage graft can be used as a primary method and if recurrence occurred chooses other complex procedure.
