The use of heterogeneous acellular dermal matrix in the closure of hard palatal fistula

Abstract Objective The aim of this study was to evaluate the efficacy of closure of hard palatal fistula using Heal-All ® Oral Biofilm, a heterogeneous acellular dermal matrix graft. Patients and methods Superior lip mucosal or myomucosal flap and buccal myomucosal flap were used in 20 patients (group 1) (2000–2005); whereas, heterogeneous acellular dermal matrix graft was performed in 18 patients (group 2) (2005–2013). The recurrence in the closed fistula and the obliteration of gingivolabial and gingivobuccal sulci were seen postoperatively with follow-up appointments at 1–3 months for all cases. Results The recurrence rate of hard palatal fistula has been reduced from 25 to 11.1% with the use of heterogeneous acellular dermal matrix graft, and the rate of the obliteration of gingivolabial and gingivobuccal sulci has been decreased from 90 to 5.5%. Conclusions Closure of hard palatal fistula using Heal-All ® Oral Biofilm graft is a useful method with high success rate. It is a day-case procedure especially to avoid dividing the pedical of the flap after follow-up, and the gingivolabial and gingivobuccal sulci do not need further procedures to deep with follow-up.
