About this study
Official title: Post-operative Pain Control With Sphenopalantine Ganglion Nerve Block in Septorhinoplasty Patients
Maxillary nerve blocks have been shown to significantly reduce post-operative pain and analgesic intake during the 24-hour period following sinus surgery. This randomized, double-blinded, placebo-controlled study will investigate blocks of the sphenopalatine ganglion using a suprazygomatic approach during septorhinoplasty surgery. It is the investigator's hypothesis that this technique will result in decreased post-operative pain and opioid use, and the morbidity associated with it.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
RopivacaineDrug
A single injection into the pterygopalatine fossa bilaterally of 0.5% ropivacaine at a dose of 20 mg (each side)
DexamethasoneDrug
Plus 4 mg dexamethasone
PlaceboDrug
A single injection into the pterygopalatine fossa bilaterally of a balanced crystalloid intravenous solution (4 ml of normal saline)
| Study group | Role | What they receive |
|---|---|---|
| Group 1: Ropivacaine plus Dexamethasone | Experimental | The group 1 injection procedure will be performed as follows: after preparation of the skin using appropriate skin preparation solution and using aseptic technique, a small-gauge spinal needle will be advanced into the pterygopalatine fossa under ultrasound guidance. Once the needle is properly positioned, 0.5% ropivacaine will be administered at a dose of 20 mg plus 4 mg dexamethasone and the needle will be removed. This procedure will be performed bilaterally Receives: Drug: Ropivacaine; Drug: Dexamethasone |
| Group 2: Placebo plus Dexamethasone | Active comparator | In group 2 the same procedure will be performed, but the injectate will consist of 5 mL of a balanced crystalloid intravenous solution (4 ml of normal saline) plus 4 mg dexamethasone (each side). This procedure will be performed bilaterally. Receives: Drug: Dexamethasone; Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Post Operative Pain Scores
To assess if bilateral sphenopalatine nerve blocks can decrease post operative pain scores on a scale from 0-10, with a 0 meaning no pain and 10 meaning extreme pain. Pain scores were assessed on post operative days 1, 3 and 5.
Measured: 5 days +/- 2 days
Secondary outcomes (2)
Post Anesthesia Care Unit Duration
To assess if bilateral sphenopalatine nerve blocks results in decreased post-anesthesia care unit observation time (assessed in minutes). Patients are transferred to the post-anesthesia care units immediately following completion of surgery.
Measured: 60-180 minutes
Text Message Survey Collection
To assess the efficiency of SMS based survey for post-operative data collection
Measured: 5 days post-operatively +/- 1 day

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Ropivacaine and Dexamethasone in people with Deviated Nasal Septum, run by University of Florida at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 27 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 27 Apr 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Post Operative Pain Scores (time frame: 5 days +/- 2 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Apr 2026.
