Ultrasound-Guided Versus Brainlab Navigation Sphenopalatine Ganglion Block in Functional Endoscopic Sinus Surgery

Ultrasound-Guided Versus Brainlab Navigation Sphenopalatine Ganglion Block in Functional Endoscopic Sinus Surgery: A Randomized Clinical Trial

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

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.

Inclusion Criteria:

• Age from 18 to 65 years.
• Both sexes.
• American Society of Anesthesiologists (ASA) physical status I-II.
• Patients undergoing functional endoscopic sinus surgery under general anesthesia.

Exclusion Criteria:

• Patients having a history of severe renal, hepatic, respiratory, cardiac disease, or a neurological condition.
• Drug or alcohol abuse.
• Chronic pain requires major analgesics, sedatives, or corticosteroids.
• Pregnant and lactating women.
• Hypersensitivity to local anesthetic agents.
