Repair of Oronasal Fistulae Using Auricular Cartilage Grafts in Five Cats

Abstract

Chronic oronasal fistulae refractory to conventional repair can be treated by use of auricular free graft (pinna or annular cartilage) without disfigurement. Use of annular cartilage to support palatal repairs offers surgeons an additional option when other methods have failed. We recommend using conchal cartilage as the initial treatment approach for repair of small oronasal fistulae in cats.

“…The most rostral palate and the floor of the nasal vestibule are reconstructed. 20 An alternative for repair of defects in the rostral or midportion of the hard palate is the use of a tongue flap. Reconstructive cutaneous surgery completes the repair.…”

“…Alternatively, prostheses have been used with some success (Lee, 2006). Recently, Cox et al, (2007) have also described the successful use of an auricular free graft (pinna or annular Fig. 14: An area of dehiscence over the right incisive foramen is being repaired in two layers.…”

Orosinuidal and oronasal fistulas: The search for an adequate treatment

“…In humans and small animals, auricular cartilage is used to close comparable defects and fistulas; such an approach is used to close oroantral fistulas in human subjects and cats (Cox et al; Van de Wetering et al . ; Khandelwal and Hajira ).…”

“…In humans and small animals, auricular cartilage is used to close comparable defects and fistulas; such an approach is used to close oroantral fistulas in human subjects and cats (Cox et al 2007;Van de Wetering et al 2010;Khandelwal and Hajira 2018). Also, a case report of the treatment of orosinuidal fistulas in a donkey with auricular cartilage graft shows the effectiveness of this technique in equids (Stoll 2017).…”
