V-Y two-layer repair for oronasal fistula of hard palate.Int J Pediatr Otorhinolaryngol. 2010 Sep; 74(9):1054-7.IJ
Oronasal fistula represents a functional problem after cleft palate repair; its closure is technically difficult with a high recurrence rate after primary treatment. The aim of this study was to evaluate the efficacy of closure of oronasal fistula using 2 layers of oral mucoperiosteum in a V-Y manner.
Fourteen patients were subjected for repair of their oronasal fistulas using 2 layers; the first is the oral mucoperiosteum that is elevated and inverted to close the nasal side as a hinge flap, and the second is also the oral mucoperiosteum that is elevated and sutured in a V-Y manner to close the oral side.
In all cases, the fistula was completely closed at first attempt, no cases developed operative or postoperative complications. Recurrence with not recorded in any case after a follow-up period of at least 12 months.
Closure of oronasal fistula of the hard palate that may develop after cleft palate repair using a two-layer closure in V-Y manner is an easy and ideal method with a high success rate.
