Abstract
Background: The aim of this study was to evaluate the efficacy of direct endoscopic sphenopalatine ganglion injection of 2% xylocaine with epinephrine at the start of surgery in controlling postoperative pain and analgesic need after FESS in patients with chronic rhinosinusitis. Methods: This is prospective study, will be conducted on 40 selected patients, aging between 18 to 50 years old, with chronic rhinosinusitis with or without nasal polyps not responding to medical treatment divided into 2 groups ,20 patients will undergo endoscopic sphenopalatine ganglion injection with xylocaine and adrenaline, other 20 patients will undergo endoscopic sphenopalatine ganglion injection with normal saline. Patients’ post-operative pain will be assessed using a 10-cm visual analog scale (VAS) (0 = no pain, 10 = most severe pain) at day 1, day 2 , days 7 post-operatively. Results: As regards as, post-operative pain after ESS, xylocaine Injected group was less than saline -injected group with mean values at day 1, day 2 and day 7 equals 1.8± 1.8 SD, 1.4 ± 1.2 SD, 1± 1.2 SD respectively in xylocaine injected group versus, 3 ± 1.6 SD, 2.6 ± 1.3 SD, 1.5 ± 1.2 SD, respectively in saline-injected group, with P-value <0.001 at day 1, day 2 and day 7. These differences were statistically significant. No complications were reported in either groups. Conclusion: The result of this study shows that infiltration of SPG with 2% xylocaine with1:100,000 adrenaline significantly reduces the post-operative pain after FESS
