Summary

This study aimed to show the effect of sphinopalatine ganglion blockade on surgical field, hemodynamics and postoperative pain in FEES operation.

Detailed description

Functional endoscopic sinus surgery (FESS) is a minimally invasive, effective surgical technique that is commonly used to treat chronic rhino sinusitis and nasal polyposis. Intra-operative bleeding obscures the surgical view and increases the likelihood of iatrogenic complications. There are many factors that can affect the amount of bleeding experienced during surgery including both patient and surgical factors. These include severe forms of chronic sinusitis with nasal polyposis which is associated with increased vascularity, use of anticoagulant therapy, bleeding disorders, active infection, vascular tumor on the surgical site and revision surgery may affect bleeding on surgical site. Sphenopalatine ganglion (SPG) is the main sensory innervation to the nasal mucosa. The Sphenopalatine ganglion block (SPGB) is one of the regional anesthetic techniques that were used effectively before removal of nasal packing and in patients undergoing endoscopic sinus surgery under general anaesthesia to control bleeding or for postoperative analgesia

Conditions

• Nasal Polyps

Interventions

Type	Name	Description
PROCEDURE	infrazygomatic approach sphinopalatine ganglion block	A lateral fluoroscopic view of the face will be obtained with the C-arm by superimposing the mandibular rami on top of each other spinal needle with a slightly bent tip is inserted with lateral fluoroscopic guidance. superiorly and medially toward the sphinopalatine fossa. (AP) view intermittently obtained to check the depth 0.2 mL of contrast material will be injected to rule out intravascular spread and confirm spread of the dye within the sphinopalatine fossa .Local anesthetic, such as 2 mL of 1% lidocaine will be slowly injected
PROCEDURE	intranasal injection approach of sphinopalatine ganglion block	method 2 ml Lidocaine with Epinephrine 1/200000 will be injected posterior to meatus of middle concha to block terminal nerve branches of sphinopalatine ganglia
