Abstract: PURPOSE: To establish a model to quantitative histological analysis of the mandibular branch of the facial nerve in rats. METHODS: Eleven Wistar rats had their right and left mandibular branches of the facial nerve surgically removed and were sacrificed afterwards. Quantitative histological analysis was performed with: a) partial number of axons; b) partial area of the transversal cut of the nerve (9000μm²); c) partial density. The averages of partial density were obtained. The statistical study was establishe… Show more

“…Histologic evaluation included qualitative and quantitative study of the mandibular branch of the facial nerve of rats. Twelve rats, randomly chosen after electroneuromyography, were subjected to dissection, in situ fixation, and removal of the mandibular branch of the facial nerve, according to method described by Costa et al 19 This method consists of removing 3 mm of the previously fixated nerve by two transversal incisions, made 25 and 28 mm from the labial commissure. Therefore, a nerve segment with two ends—distal (D) and proximal (P)—is produced.…”

“…Existem vários modelos animais experimentais do NF, envolvendo cobaias, camundongos, primatas não humanos, cães, gatos e ratos, dentre outros (3,(27)(28)(29)(30)(31)(32)(33) (42). Além disso, defendem que a análise qualitativa, embora subjetiva, é uma interessante ferramenta quando aliada à análise quantitativa, dando ideia sobre a qualidade do tecido neural regenerado (42,50).…”
