Regeneration of guinea pig facial nerve:  the effect of hypergravity.
Exposure to moderate hypergravity improves the regenerative capacity of sectioned guinea-pig facial nerve.  The improvement in regeneration is tri-directional as follows:  a) an average 1.7 fold increase in rate of regeneration in guinea pigs subjected to hypergravity; b) a 25% enhancement of facial muscle activity following the exposure to hypergravity; and c) improvement in the quality of regeneration from an esthetic standpoint.  A good correlation was recorded between the histological structure of the severed nerve at the end of the regeneration and the clinical results.
