Conclusion
Our results suggest that olfactory training may be a valid therapeutic
option in patients with post-surgical olfactory dysfunction. It also
shows that the improvement in an olfactory performance test could be
associated with an increase in activation of smell related brain areas
and a possible reorganization process in the olfactory network,
compatible with neuroplasticity. This pilot study supports the idea that
a full scale multicenter RCT is needed to confirm these initial
findings.
