The Use of a Superiorly Based Melolabial Interpolated Flap for Reconstruction of Anterior Oronasal Fistulas: An Easy and Practical Solution.

Purpose: This study aimed to propose the use of a superiorly based melolabial interpolated flap for reconstruction of anteriorly located oronasal fistulas maxillary defects.

Materials And Methods: Using a prospective study design, we evaluated indications and outcomes of the reconstructive technique using the interpolated melolabial flap in 6 patients affected by anteriorly located maxillary defects with naso-sinonasal communication. The cases differed in demographic characteristics and etiology of the defect. The outcome variables were flap vitality/failure and persistent/recurrent oronasal fistula. Both the outcomes were clinically evaluated.

Results: No partial or total flap failures were recorded. Two patients experienced recurrent oronasal fistula after previous attempts of correction that required second surgery repair; in both cases, the melolabial flap was available and functional for the secondary procedure.

Conclusions: In selected cases, the superiorly based interpolated melolabial flap could represent a valuable choice for repairing of anteriorly located maxillary defects with oronasal fistulas.
