Abstract: To investigate the diagnosis and surgical management of schwannoma of facial nerve(SFN) and discuss the methods of repairing of facial nerve after operation. Methods： Of all 11 patients with SFN, up to 100% had been misdiagnosed. All 6 cases with simple mastoidtympanic cavity SFN underwent nerve transplantation, and in 5 of them great auricular nerve was transplanted and in 1 great auricular nerve was bridged with dried and heated skeletal muscle. And in 2 cases with tympanicmastoid cavityintracranial SFN, 1 underwent hypoglossal nerve transplantation to replace the facial nerve (loop of hypoglossal nerve was transplanted to replace the hypoglossal nerve), while the other 1 underwent loop of hypoglossal nerve transplantation into the distal end of facial nerve. All other patients had suffered from facial palsy for a long time and their facial nerve functions could not be recovered and only 1 of them underwent fascia lata femoris musculus orbicularis oris ventrofixation, while others gave up the reconstruction of facial nerve. Results： Three patients with mastoidtympanic cavityparotic gland SFN and intracranial tumor, not receiving reconstruction of facial nerve, were left with complete facial palsy. In 6 cases with simple mastoidtympanic cavity SFN, the functional recovery of facial nerves was graded with BrakmannHouse gradings in 5 cases: grade 2 in 3 cases; grade 3 in 2; recovery was not found in 1 case. Two cases whose facial nerves were reconstructed with hypoglossal nerve and loop of hypoglossal nerve were graded as level 2 and level 3, respectively. Conclusion： We believe that clinical manifestations of schwannoma of facial nerve are variform, and all round and systemic inspections should be performed to prevent
