Summary Two cases with huge dumbbell type jugular foramen meningioma with extension into the parapharyngeal space are reported. A well co-ordinated surgical strategy for total resection to this high risk tumour with neurosurgeons, otolaryngologists and plastic surgeons is mandatory to minimise operative complications. Both of our patients presented with a cervical mass and lower cranial nerve palsies, and had huge dumbbell type masses extending from the posterior cranial fossa through the jugular foramen to the parapharyngeal space, encasing the cervical internal carotid artery. Gross total resection of the tumours was successfully achieved by basically a 2-stage operation. In the first stage, posterior fossa tumours were removed by the transjugular approach, combined with the petrosal approach in one case. In the second stage, cervical tumours were removed along with the cervical carotid artery by the transcervical and/or transmandibular approach, followed by vascular reconstruction from the ipsilateral carotid artery to the middle cerebral artery using saphenous vein graft. From these experiences, we recommend this 2-stage operation for large dumbbell type meningiomas extending to the infratemporal/parapharyngeal space. The intracranial tumour is removed at the first operation. The extracranial portion is resected at the second, and if necessary, the involved cervical carotid artery is resected and simultaneous revascularisation using saphenous vein graft is performed with a vascularised free muscle graft. This strategy could maximise the functional preservation on the one hand, and minimise the surgical risk, such as postoperative infection, on the other.
