CARTILAGEM HOMÓLOGA CONSERVADA EM GLICERINA PARA RESTAURAÇÃO DE FENDA DE PALATO DURO EXPERIMENTAL EM CÃES HOMOLOGOUS CARTILAGE GLYCERIN PRESERVED IN CANINE EXPERIMENTAL PALATE CLEFT

Palate cleft can be a congenital or acquired defect, occurring in any canine race. The main clinical signals are regurgitation of fluid into the nasal cavity and respiratory tract recidivant infections. The palate cleft was experimentally induced in 16 dogs, which were separated in two groups. The palatoplasty in GI group was made immediately after the palate cleft induction, with a flap from mucoperiosteum. In GII group the palatoplasty was accomplished 21 days after palate cleft induction, with a graft of homologous pinna auricular cartilage, maintained in glycerin 98%, between the palatal bone and mucoperiosteum flap. In group GII was done microbiological collect through a swab to growing, identification and antibiogram tests, during the time of palate cleft maintenance and palatoplasty was realized after identification of bacterial flora present in the cleft, using specific antibiotic. After 10 Th day was observed cicatrization of oral mucosa in five (GI) and seven (GII) animals. Rhinoscopy showed complete regeneration in nasal mucosa at 60 days after palatoplasty. The radiography and histological evaluation showed complete bone fusion in GII animals earlier than GI animals, showing useful interference of graft in bone cicatrization.
