Most of the studies were based on the sciatic nerve rather than the facial nerve. In this narrative review, we evaluated the results of different types of stem cells, various types of biomaterials/scaffolds for fabricating tissue-engineered nerve including natural, synthetic hybrid polymers, and in combination with different growth factors. We have also reviewed whether stem cell-based tissue-engineering promotes regeneration of facial nerve in the most recent and the most relevant studies to treat facial nerve injury that can help newcomers acquainted themselves with the field of tissue engineering.
