Re: Novel approach in the treatment of a persistent oroantral fistula using an acellular dermal graft: technical note

We read with interest the technical note by Blythe et al on the use of an acellular dermal graft to close a persistent oroantral fistula.1 For the last two years we have been using a similar dermal regeneration system called Integra© (Integra LifeSciences Corporation, Plainsboro, NJ, USA) as an adjunct to closing large or recurrent fistulas. It is derived from shark skin rather that material from cadavers.
