Design outcomes

Primary

Measure	Time frame
To compare the Analgesic efficacy of Ultrasound-Guided Suprazygomatic Maxillary Nerve Block Versus Transnasal Sphenopalatine Ganglion Block in patients undergoing FESS surgeries during Postoperative period, using VAS score.Timepoint: Postoperatively at 1,2,4,6,8,10,12 and 24 hours using VAS score.	—

Secondary

Measure	Time frame
To assess the ease of block technique in terms of duration Timepoint: Time taken from the start of ultrasound imaging to visualize the landmarks until the time of drug deposition;To assess the requirement of rescue analgesiaTimepoint: onset of first analgesic requirement & total rescue analgesic consumption for 24 hours postoperatively.;To assess the patient satisfactionTimepoint: Patient satisfaction score will be recorded after 24 hours postoperatively;To assess the hemodynamic stability of the patientTimepoint: At postoperative period 1,2,4,6,10,12 & 24 hours;To assess the postoperative complications such as nausea, vomiting, hematoma & nerve injuryTimepoint: Postoperative complications will be assessed after 24 hours postoperatively	—
