V-Y two-layer repair for oronasal fistula of hard palate

Abstract

Objective: 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.

Methods: 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.

Results: 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.

Conclusion: 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.
