Postop Pain Management in Pituitary Tumour Patients

This study looks at pain management after surgery to remove a pituitary tumor through the nose (endonasal approach). Researchers want to find out whether a nerve-blocking technique can help reduce pain and the need for strong pain medications after this type of brain surgery. **You may be eligible if...** - You are 18 years or older - You are scheduled to have a pituitary adenoma removed through your nose (endonasal surgery) **You may NOT be eligible if...** - You already take antidepressants (SSRIs), benzodiazepines, gabapentin, or opioids for a chronic pain condition - You have a known allergy to the medications used in the nerve block - You have chronic alcohol abuse, severe high blood pressure, serious kidney or liver disease, or certain heart conditions (like irregular heart rhythms or cardiomyopathy) Talk to your doctor to see if this trial is right for you.
