The armamentarium for anterior skull base (ASB) reconstruction includes a variegate spectrum of grafts, endonasal pedicled flaps, regional pedicled flaps, and free flaps, which are selected to face specific scenarios. The use of a vascularized flap in case of large ABS defects ensures an adequate blood supply. The aim of this study was to evaluate the possible role of temporoparietal fascia flap (TPFF) in ASB reconstruction. ⋯ The supraorbital epidural corridor is a possible novel pathway for transposition of the TPFF for ASB reconstruction. Side-door TPFF was shown to be an ideal choice for large ASB defect with lateral supraorbital extension and could be useful in the scenario of salvage reconstruction for recurrent ABS cerebrospinal fluid leak.

We have discussed the clinical features and neuroimaging findings and investigated the correlations between the clinical characteristics and different neuroradiologic phenotypes of cerebral small vessel disease (CSVD). ⋯ The present study has provided a comprehensive analysis of the clinical correlation of characteristics and neuroradiologic phenotypes in patients with CSVD. The insights from these findings could be used to refine the management strategy for patients with CSVD.

To study whether and when mere dorsal decompression is enough in the full endoscopic key hole technique for foraminal stenosis. ⋯ Stenosis is mainly caused by dorsal structures; mere dorsal decompression is enough. In both cases, the ventral and dorsal structures contributed to the stenosis. When there is no herniated soft fragment contributing to the stenosis, ventral decompression is not always necessary. If intraoperative exploration detects less tension formed by the ventral abnormal structures, mere dorsal decompression is enough to settle the symptoms.

Microvascular decompression surgery is the most effective treatment for hemifacial spasm (HFS). The vertebral artery (VA) is a larger and more elastic vessel, which makes surgical management more difficult. We introduce a surgical technique of proximal Teflon transposition with interposition (PTTI) in the vertebromedullary space for HFS with a VA offender. ⋯ The PTTI technique can be considered as another treatment option in addition to the transposition technique reported previously.

Revascularization is an important strategy when treating cerebrovascular occlusive disease and complex aneurysms. Radial artery fascial flow-through free flaps (RAFFs) are flexible grafts that provide direct and indirect revascularization. RAFFs can be especially useful for large territory revascularization and can be combined with other direct bypasses. ⋯ Postoperative angiography demonstrated patency of both direct grafts. The patient suffered small pericallosal infarcts because of retraction and perforator sacrifice at the revascularization site. At early follow-up, the patient was at his neurologic baseline, and at 1-year follow up, the patient had no additional infarcts on imaging and was living independently.
