We aimed to investigate the effects of bilateral sphenopalatine ganglion blockade (SPGB) on postoperative early complications in septorhinoplasty operations.

Septorhinoplasty is a surgical procedure that corrects the nasal septum (the wall between the nostrils) and reshapes the nose. After this surgery, patients can experience significant pain, as well as unpleasant side effects like nausea, vomiting, and sore throat. This study is testing whether blocking the sphenopalatine ganglion — a small nerve cluster located at the back of the nasal cavity — on both sides can reduce post-operative pain and discomfort more effectively than standard care. The sphenopalatine ganglion block (SPGB) is a simple procedure performed by placing local anaesthetic near the nerve cluster. Participants will be randomly assigned to receive either the nerve block before surgery or standard anaesthesia alone. Pain scores, the need for extra pain medication, and side effects like nausea and vomiting will be assessed for the first 24 hours after surgery. You may be eligible if you are aged 18–50 and are scheduled for an elective septorhinoplasty procedure. People who are pregnant, have known drug allergies relevant to the study, have significant heart or kidney conditions, or are not willing to participate are not eligible.
