BACKGROUND: Necessity of new and alternative treatments in traumatic facial nerve injury.
AIMS/OBJECTIVE: In this experimental study, we aimed to evaluate the histopathologic and functional effects of methylprednisolone, hyperbaric oxygen and hesperidin + diosmin treatments on traumatic facial nerve regeneration in rats.
METHODS: After facial nerve injury, five groups were formed with eight rats in each group: Group 1 (negative control), 2 (operation), 3 (corticosteroid), 4 (hyperbaric oxygen), 5 (hesperidin + diosmin). Blink reflex of rats evaluated a day after the operation and at the first, second and third weeks. Facial nerve samples from sacrificed animals were examined under a light microscope.
RESULTS: According to our results, in group 4; axonal degeneration and vascular congestion were significantly lower than group 2 and 3, and myelin sheath thickness was significantly higher than group 3. In group 5; axonal degeneration was significantly lower than group 2 and vascular congestion was significantly lower than group 2 and 3. In terms of functional recovery; there was no statistically significant difference between the groups.
CONCLUSIONS AND SIGNIFICANCE: It has been shown that both hyperbaric oxygen and hesperidin + diosmin treatments have positive effects on facial nerve regeneration. Both treatments may be good alternatives for ameliorating traumatic nerve injury, but these treatment modalities need to be further explored.
