It is crucial for surgeons to adopt surgical strategies that adequately address sphenoid pathology while minimizing surgical risks and optimizing outcomes. Unlike the well-established surgical approach nomenclature for the maxillary and frontal sinuses, a standardized nomenclature for sphenoid sinus surgery has yet to be established. Hence, we provide a comprehensive review of the various techniques to approach the sphenoid sinus and propose a common surgical classification system to better identify and categorize these surgical approaches. Each surgical technique has been classified based on the extent of surgery, anticipated operation time, level of surgical complexity, potential complications, and expected wound healing time, ensuring alignment with established standards in the literature. The proposed sphenoidotomy types are <b>Type I</b>: sphenoid ostial dilation; <b>Type IIa</b>: transnasal sphenoidotomy (sphenoidotomy without ethmoidectomy); <b>Type IIb</b>: transethmoidal sphenoidotomy (sphenoidotomy with ethmoidectomy); <b>Type III</b>: bilateral, common cavity sphenoidotomy, or \"sphenoid drill-out\", <b>Type IV</b>: transpterygoid approach, to expose the lateral sphenoid sinus recess, and <b>Type V</b>: sphenoid nasalization, completely removing the sphenoid sinus floor.

Glucocorticoids (GCs) are extensively utilized for their potent anti-inflammatory effects in managing various inflammatory conditions and also play a pivotal role in treating CRS. Certain patients exhibit insensitivity to GC therapy, leading to GC resistance (GCR). Oxidative stress is one causative factor for GCR development, while the Nrf2 signaling pathway emerges as a critical cellular defense mechanism against oxidative stress-induced damage. Exploring the Nrf2 signaling pathway is promising for advancing our understanding of GC sensitivity and its application in treating CRS. This article overviews the relationship between GC sensitivity and the Nrf2 signaling pathway and potential Nrf2-related drugs.
