Efficacy of pterygopalatine fossa injection with local anesthetic agent and adrenaline in reduction of intra-operative bleeding during endoscopic sinus surgery

Abstract Background This study aimed to assess the effect of pterygopalatine fossa injection via greater palatine canal with xylocaine and adrenaline on intra-operative surgical field bleeding overall blood loss during FESS. Methods We are doing this randomized blinded 60 patients who underwent Infiltration 2 ml 2% 1:100,000 was slowly injected one side surgeon asked using a Boezaart scale. Results Operative time is significantly less in cases than other P value < 0.001. Non-injected Conclusion There significant decrease loss, duration surgery, improvement visual score group (cases) xylocaine/adrenaline compared non-injected group.
