This video demonstrates the bilateral suprazygomatic maxillary nerve (SZMN) block performed using both landmark-based and ultrasound-guided techniques for intraoperative and postoperative analgesia in a 12-month-old child undergoing cleft palate repair. The maxillary nerve, located within the pterygopalatine fossa, is the second division of the trigeminal nerve (V2) and is a purely sensory nerve that supplies sensation to the midface, including the palate.

Irreversible Electroporation for Treatment of Locally Advanced Pancreatic Cancer
Contributors: Robert C.G. Martin, II
Locally advanced pancreatic cancer (Stage 3) is defined by encasement or abutment of vital venous and arterial structures. Irreversible electroporation (IRE) represents an effective local non-thermal ablation modality for treatment of solid tumors involving critical vascular and biliary structures. Electroporation creates pores in the cell membrane and disrupts the ionic gradients while sparing the extracellular matrix, resulting in preservation of blood vessel and biliary scaffolding.
