Oronasal fistulas are sequelae to periodontal disease in dogs. Previous case series have described the use of auricular cartilage as a type of membrane to help with surgical repair of oronasal fistulas. This case series explores the use of a commercially available flexible bone membrane in the surgical repair of ten acquired oronasal fistulas in dogs. The use of the flexible bone membrane did not necessarily improve the surgical outcomes in these cases; however, larger controlled trials are necessary to further evaluate its use.
