About this study
Official title: Ultrasound-guided Superficial Cervical Plexus Block for Pain Management After Orthognathic Surgery.
US-guided superficial cervical plexus block (SCPB) may be used for several head and neck surgeries. Local anesthetic is injected under the sternocleidomastoid muscle for SCPB. It has lower complication rate compared to the deep cervical plexus block. Postoperative pain management is important in patients underwent orthognathic surgery. Effective pain treatment provides early mobilization, and shorter hospital stay.
Read the detailed description
Postoperative pain management is very important in patients underwent orthognathic surgery. Effective pain control provides early mobilization, shorter hospital stay and it increases the satisfaction of the patients. Opioid agents may provide effective pain management, however opioid agents have undesirable adverse effects such as respiratory depression, sedation, constipation, nausea and vomiting etc. Ultrasound (US) -guided regional anesthesia techniques may be preferred for pain management in patients underwent orthognathic surgery. Regional anesthesia techniques may provide effective postoperative pain management as a part of multimodal analgesia regimens. US-guided bilateral superficial cervical plexus block (SCPB) have been performed for several head and neck surgeries and it provides effective pain control. The cervical plexus presents between the longus capitis and middle scalene muscles, under the prevertebral fascia. It is formed by the C2-4 cervical spinal nerves. There are the end points of these nerves in the interfascial area under the SCM. Thus, the superfascial branches of the cervical plexus may be blocked by injecting local anesthetic under the SCM. Cervical plexus may be blocked with deep or superficial technique. The deep CPB is defined as a paravertebral block. The deep branches may be targeted by this method. However it has some major disadvantages such as intravascular injection, epidural or subarachnoid injection, and phrenic nerve palsy, due to the deepness of the injection. Otherwise; SCPB is a superficial method and it has lower complication rate compared to the deep CPB. In an anatomical study, it has been reported that with SCPB there was spread of dye into the deep cervical fascia. The authors emphasized that this mechanism may explain the efficacy of the SCPB. Thus, with the SCPB both the superficial branches and the deep nerve roots may be blocked. Therefore, SCPB may provide effective pain management following orthognathic surgery. In the literature, there are no randomized clinical studies about pain management with US-guided SCPB after orthognathic surgery, yet.
The aim of this study is to evaluate the efficacy of the US-guided SCPB for postoperative analgesia management after orthognathic surgery. The primary aim is to evaluate postoperative opioid consumption and the secondary aim is to evaluate postoperative pain scores (VAS), adverse effects related with opioids (allergic reaction, nausea, vomiting) compared to no intervention control group.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Group SCPBOther
In group SCBP, SCBP block will be performed. Patients will be administered dexketoprofen 50 mgr IV every 8 hours in the postoperative period. A patient controlled device prepared with 10 mcg/ ml fentanyl will be attached to all patients with a protocol included 10 mcg bolus without infusion dose, 10 min lockout time and 4 hour limit.
| Study group | Role | What they receive |
|---|---|---|
| Group S = SCPB group | Active comparator | US-guided SCPB will be performed at the end of the surgery before extubation, with patients in the supine position by using US (Vivid Q, GE Healthcare, US). Under aseptic conditions using 10% povidone iodine, the high frequency linear probe (11-12 MHz, Vivid Q) will be covered with a sterile sheath and a 22G, 50 mm block needle (Braun Stimuplex Ultra 360, Germany) will be used.
Sternocleidomastoid (SCM) muscle will be visualized. The 22 G needle will be inserted between the SCM and the prevertebral fascia by using in plane technique horizontally. The needle tip will be corrected with injecting 2 ml of normal saline. Then a 20 mL dose of 0.25% bupivacaine will be injected here. The same procedure will be performed for the opposite site (totally 40 mL dose of 0.25% bupivacaine). Receives: Other: Group SCPB |
| Group C = Control group | No intervention | Patients will be administered dexketoprofen 50 mgr IV every 8 hours in the postoperative period. A patient controlled device prepared with 10 mcg/ ml fentanyl will be attached to all patients with a protocol included 10 mcg bolus without infusion dose, 10 min lockout time and 4 hour limit. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Opioid consumption
The primary aim is to compare postoperative opioid consumption
Measured: Change from baseline opioid consumption at postoperative 1, 2, 4, 8, 16, and 24 hours
Secondary outcomes (1)
Pain scores (Visual analogue scores-VAS)
Postoperative pain assessment will be performed using the VAS score (0 = no pain, 10 = the most severe pain felt). The VAS scores will be recorded
Measured: Changes from baseline pain scores at postoperative 1, 2, 4, 8, 16, and 24 hours.

Questions about this trial
What is this clinical trial studying?
A study testing Group SCPB in people with Maxillofacial Injuries and Maxillofacial Trauma, run by Medipol University at 1 site in Turkey (Türkiye).
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 2 inclusion and 6 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: withdrawn, as of the sponsor's last update on 4 May 2022. 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 Turkey (Türkiye). 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.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
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?
Opioid consumption (time frame: Change from baseline opioid consumption at postoperative 1, 2, 4, 8, 16, and 24 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04442009, which also lists 3 linked publications.
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 4 May 2022; AzTrials last refreshed its copy on 31 Oct 2026.
