[Healing of zygomatic arch fractures in rats with lesions of the median hypothalamic eminence].
The purpose of this study was to verify the effect of hypothalamic median eminence lesion on healing process in fracture of anterior portion of zygomatic arch, in rats, by histologic evaluation. The animals were killed in number of 5 for each periods at 6, 12, 24 and 36 days post-lesion. Our results showed morphologic changes and tinctorial in all considered periods, with more evidence at 12 and 24 days post-fracture and evidents signals of hipomineralization. This disfunction appeared only after a mean period of 12 days post-lesion.
