Network-like reconstruction is surgical rehabilitation for incomplete facial palsy, and includes end-to-side for neural signal augmentation and neural supercharge, which originated from nerve crossovers. Numerous motor nerves, such as the hypoglossal, spinal accessory, and masseteric branch of the trigeminal nerve, were reported as neural sources of nerve crossovers for facial palsy, but the hypoglossal nerve is the most commonly used. The history of hypoglossal crossover is reviewed in this article. The superiority of the hypoglossal nerve as a neural source of nerve crossovers and network-like reconstruction for facial palsy is due to the following points : 1）the centers of the movements of the face and tongue overlap in the cortex 2）hypoglossal and reticular interneurons may be involved in oro-facial coordination, and 3）central reorganization of the blink reflex is induced because of central nerve plasticity. Further review to compare the hypoglossal nerve with other available cranial nerve transfers, such as the masseter nerve, is warranted.
