The endoscopic endonasal approach to the infratemporal fossa (ITF) has gained popularity. However, the inferior turbinate and/or lacrimal duct are often removed when performing endoscopic medial maxillectomy for ITF approach, and there is potential risk for empty nose syndrome or epiphora. Although the endoscopic prelacrimal recess approach was introduced to avoid these complications, there were some limitations associated with surgical freedom. We report a 2-port endoscopic technique using both prelacrimal recess and antral window as a means to preserve the inferior turbinate and lacrimal duct, while facilitating instrument availability during ITF tumor resection. ⋯ We propose a hybrid endoscopic surgical procedure for ITF tumors using both endoscopic prelacrimal recess approach and transantral window. This technique provides surgeons an adequate working space via a bimanual technique through 2 different ports, while preserving normal sinonasal structures.

Parasagittal and parafalcine (PSPF) meningiomas recur more frequently than other intracranial meningiomas owing to the difficulty in achieving gross total resection. The present study investigated the preoperative magnetic resonance imaging (MRI) features for the prediction of progression/recurrence (P/R) in benign PSPF meningiomas with an emphasis on the apparent diffusion coefficient (ADC) values. ⋯ The preoperative ADC values and ratios for the prediction of P/R offer additional valuable information for the treatment planning for PSPF meningiomas.

To evaluate the feasibility and clinical value of magnetic resonance diffusion tensor imaging (DTI) with fluorescein sodium staining (FLS) in the resection of high-grade glioma (HGG) in functional brain areas. ⋯ The application of DTI with FLS can facilitate the maximum resection of HGG in functional brain areas with minimum loss of fiber tracts, reduce the disability rate, and improve quality of postoperative life compared with traditional glioma surgery.
