Summary

Functional endoscopic sinus surgery (FESS) is a minimally invasive procedure that is used in many inflammatory and infectious sinus diseases. Acute postoperative pain can lead to adverse consequences and good postoperative treatment of pain is essential. There is no agreement on a single protocol to treat pain after endoscopic sinus surgeries, and the usually used analgesics have some side effects that hinder their use. Current evidence is insufficient for routine clinical use of the sphenopalatine ganglion block for Functional endoscopic sinus surgery and the efficacy of sphenopalatine ganglion block for pain control after functional endoscopic sinus surgery remains controversial. This study aims to explore the influence of sphenopalatine ganglion block on pain intensity after functional endoscopic sinus surgery by comparing two groups, a group receiving the block with Bupivacaine injection, versus saline injection in the other group.

Conditions

• Anaesthesia

Interventions

Type	Name	Description
PROCEDURE	Sphenopalatine Ganglion Block trans oral approach saline injection	The sphenopalatine block will be done by the end of the operation using a trans-oral approach at the greater palatine foramen with the help of a Macintosh blade number 3 for good visualization of the hard and soft palate using a 25 Gauge 1.5 inch needle curved at 45 degrees 25 mm from the tip and filled with 1.5 ml of normal saline. The greater palatine foramen is located posteromedial to the third maxillary molar and anteromedial to the pterygoid hamulus and maxillary tuberosity. The foramen will be identified by digital palpation, and the needle will be inserted until reaching the bone then redirected slightly until the foramen is localized and the needle easily gets in the greater palatine canal. aspiration will be done to ensure that no blood vessels are punctured, and the solution will be injected.
