About

This study compares ultrasound-guided and Brainlab navigation sphenopalatine ganglion block (SPGB) in functional endoscopic sinus surgery (FESS).

Full description

Functional endoscopic sinus surgery (FESS) is the treatment modality of choice for the inflammatory disease of paranasal sinuses.

Sphenopalatine ganglion block (SPGB) is a regional analgesic technique that can be used as an alternative approach to reduce blood loss and improve the operative field during FESS without the need for hypotensive agents.

Ultrasound (US)-guided nerve block is a well-established technique in regional anesthesia and offers the advantage of real-time visualization of neural and vascular structures.
