Stimulation of Trigeminal Afferents Improves Motor Recovery After Facial Nerve Injury Functional, Electrophysiological and Morphological Proofs /
Its is commonly known that the recovery of mimic functions after facial nerve injury is poor: a successful regrowth of the lesioned axons to their muscle targets is compromised by (i) poor navigation of the growth cones and excessive collateral axonal branching, (ii) abnormal exchange of nerve impul...

Tabla de Contenidos:
- First major set: mild indirect stimulation of the trigeminal afferents after combined surgery on the infraorbital and facial nerves by removal (clipping) of the contralateral vibrissal hairs.- Second major set: intensive indirect stimulation of the trigeminal afferents after facial nerve surgery by extcision of the contralateral infraorbital nerve
- Third major set: direct stimulation of the trigeminal and facial nerves after facial nerve surgery by massage of the vibrissal muscles .- Fourth major set: direct stimulation of the trigeminal and facial nerves after facial nerve surgery by application of electric current to the vibrissal muscles.- RESULTS.- Mild indirect stimulation of the trigeminal afferents after combined surgery on the infraorbital and facial nerves by removal of the contralateral vibrissal hairs improves vibrissal function.- Intensive indirect stimulation of the trigeminal afferents by excision of the contralateral ION attenuates the degree of collateral axonal branching and improves the accuracy of muscle reinnervation.- Direct stimulation of the trigeminal and facial nerves by massage of the vibrissal muscles improves the quality of target reinnervation and promotes full recovery of whisking function.- Direct stimulation of the trigeminal and facial nerves by electric current to the vibrissal muscles fails to improve quality of target reinnervation and does not promote recovery of vibrissal function.- DISCUSSION.- Mild indirect stimulation of the trigeminal afferents by removal of the contralateral vibrissal hairs has a beneficial effect on motor recovery.- Beneficial effect of the intensive indirect stimulation of the trigeminal afferents by excision of the contralateral ION.- Complete recovery of motor function after direct stimulation of the trigeminal and facial nerves by massage of the vibrissal muscles.- Deleterious effect of the direct stimulation of the trigeminal and facial nerves by application of electric current to the vibrissal muscles . - conclusion
