Use of n-butyl cyanoacrylate glue in the recession sulcoplasty in rabbits: histologic study

> size="2" face="Verdana, Arial, Helvetica, sans-serif">The aim of this study was to analyze the glue composed by n-butyl cyanoacrylate, as an auxiliary in the fixation of the bone wedge at the recession sulcoplasty procedure and the interference in the healing. Nine male Norfolk rabbits, initially weighing from 3 to 3.5 kg were used. After epidural anesthesia, a medial parapatellar approach was used and a V-shaped osteochondral wedge was removed from the trochlea. In the right stifle joint, before the osteochondral wedge replacement two glue drops were used. In the left stifle joint, considered as control, the osteochondral wedge was only replaced. Three animals were submitted to euthanasia at five, 15 and 30 days of postoperative period. Macroscopic evaluation showed that in both stifles the osteochondral wedge was stabilized on the receptor bed during all observation periods. It was possible to conclude, based on microscopic evaluation, that the glue did not induce accentuated inflammatory process and foreign body reaction, but it had a negative influence because the healing process was retarded.
