Aim and objective
A prospective study done to evaluate the efficacy of tongue flaps in secondary palatal defects, in terms of functionality, esthetics, and donor site morbidity, and to clarify the technique of elevating and insetting of tongue flap.
Materials and method
Twenty patients having recurrent secondary palatal fistula, post cleft treatment were treated with anteriorly and posteriorly based dorsal tongue flaps. Patients were evaluated for outcome in terms of flap uptake and effectiveness, correction of oronasal regurgitation, speech and articulation, donor site morbidity, and esthetics.
Results
Twenty patients in age range of 11–24 years, with secondary palatal fistulae, were treated with anteriorly/posteriorly based tongue flap. There were two recurrences as the flap got detached in one patient and necrosis of flap in another. In other patients, healing was uneventful. The flap showed good success rate in terms of uptake and correction of oronasal regurgitation, with imperceptible donor site morbidity. With speech therapy assistance and periodic evaluation by a therapist, significant improvement in speech and articulation was noted over time in all successfully healed patients.
Conclusion
Use of tongue flap for repair of palatal fistulae is a successful technique as it provides appreciable quality and quantity of well-vascularized tissue for fistula closure with negligible functional and esthetic morbidity associated with donor site. As per our study, it is a reliable technique for palatal fistula closure. It even provides good speech improvement over time.
