Using Reverse Flow Based Flap VS Palatal Pedicled Flap for Closure of Recurrent Small & Medium Sized Oronasal Fistula.

Patient Satisfaction Clinical Trial

Official title: Patient Satisfaction After Using Reverse Flow Based Facial Artery Musculomucosal Flap (FAMM) Versus Palatal Pedicled Flap for Closure of Recurrent Small and Medium Sized Oronasal Fistula. A Randomized Clinical Trial.

Status Completed

Clinical Trial Summary

Research question: What are the outcomes of using the Facial artery Musculomucosal (FAMM) Flap to close recurrent small and medium sized oronasal fistulae based on reverse flow on patient's satisfaction versus using the Palatal Pedicled flap? Statement of the problem: To determine whether the using the Facial artery Musculomucosal (FAMM) Flap to close recurrent small and medium sized oronasal fistulae which are difficult to manage could meet the patients satisfaction regarding both success and function versus using palatal pedicled flap

Clinical Trial Description

Oronasal fistulae (particularly those of the anterior palate) are often difficult to close because the buccal cavity is narrow and the palatal mucosa is not extensible. Historically, skin flaps (forehead or nasolabial skin flaps) were first used to close such defects. but they leave a conspicuous scar. Mucosal flaps, which were empirically harvested from the cheek mucosa have also been used occasionally, but unpredictable results discouraged further attempts. A more accurate description of the vascularization of the buccal mucosal has allowed the design of axial-pattern flaps. The buccinator musculomucosal flap was first introduced as an island flap supported by the facial pedicle, and was then used successfully as an axial pattern flap that was vascularized by the buccal artery according to Bozola et al. or the facial artery according to Carstens et al. The FAMM (facial artery musculomucosal) flap was introduced by Pribaz et al. in 1992 and its main advantage is its long rotational arc that allows closure of defects of the anterior palate that were formerly a reconstructive challenge. Pribaz et al. gave an accurate description of the dissection of the flap, but variations in the course of the facial artery sometimes preclude its use. Previous studies involving FAMM flap were applied to oronasal fistula repair either recurrent or as first attempt were described in repair of alveolar clefts, anterior palatal fistulae and in recurrent fistulae after palatoplasty in cleft patients either superior or inferior pediceled flap. In cases of hypovascular bed, it increases the chances for failure of other techniques of closure. The palatal pedilced flap was reported in the literature as one of the regional flaps for closure of oronasal fistulae. The previous studies included case series, with no any randomized clinical trial. This study compares using FAMM flap versus Palatal Pedicled flap in a randomized clinical trial in closure of recurrent oronasal fistulae. Aim of the study To evaluate the effect of using FAMM for closure of recurrent small and medium sized oronasal fistula on patient's satisfaction versus using the palatal pedicled flap. ;
