Infiltration in the Region of the Palatine Ganglion Spheno by Ropivacaine on Postoperative Pain
Endoscopic sinus surgery (ESS) is a prevalent surgical procedure. It is required in many
 chronic rhinosinusitis for whom the medical treatment failed. In order to improve the
 postoperative management of patients treated with ESS, we aim to assess the analgesic action
 of local injection of ropivacaine in the nasal fossa.
A prospective randomized double blind placebo controlled study was designed. Local injection
 of ropivacaine or placebo was conducted at the end of the surgical procedure in both nasal
 fossa through endoscopic view in the sphenopalatine region.

 Pain was measured in the postoperative course with visual analogic scale in the recovery room
 and the rhinologic department.
