Lidocaine Versus Bupivacaine for Sphenopalatine Ganglion Block

"The SPGB will be done after the patient is generally anesthetized and will be performed by the operating surgeon using a transnasal endoscopic approach through the posterior and over the middle turbinate tail in the pterygopalatine fossa.~The patient will be placed in the supine position with head extension. The prepared solution (4 ccs 2% lidocaine or 0.5% bupivacaine or normal saline and 1 cc 8 mg dexamethasone) will be given (2,5 cc) to each side of the nose.~The surgery was started 10 minutes after the application of SPBG to allow sufficient time for the block to develop."
