Article Synopsis
  • * This study investigated the relationship between the ethmoidal bulla and uncinate process, finding that they are fused at their upper ends, creating a consistent landmark that can assist surgeons during surgeries involving the ethmoid and frontal recess.
  • * Advanced imaging techniques, such as high-resolution 3D CT scans, provide detailed insights into sinonasal anatomy that can enhance surgical planning, potentially improving outcomes for minimally invasive procedures.
