Abstract：Objective To explore the clinical effects of microsurgery via suboccipital retrosigmoid approach on the cerebellopontine angle (CPA) tumors with onset of trigeminal neuralgia (TN) and hemifacial spasm (HFS). Methods The clinical data of 21 patients with CPA tumor with onset of TN and HFS, who underwent surgery from September, 2014 to September, 2016, were analyzed retrospectively. The surgery via the suboccipital retrosigmoid approach for CPA tumors was performed in all the patients. Seventeen patients underwent microvascular decompression (MVD) for TN and HFS at the same time. Results The CPA tumors were totally removed in 18 patients and subtotally in 3. The clinical manifestations of TN and HFS disappeared or significantly decreased after the operation in all the patients. There were no serious complications such as hematoma, ischemia, acute hydrocephalus and death. During the follow-up from 3 to 27 months, no TN, HFS and tumor recurred in all the patients. Conclusions The CPA tumor may only manifest the symptoms and signs of TN or HFS and MRI examination can provide the information for its early diagnosis. The curative effects of the surgery via suboccipital retrosigmoid approach on CPA tumors with onset of TN and HFS are good. MVD is recommended if the vessels responsible for TN and HFS are found during the surgical resection of the tumor.
