Study summary

  • Endoscopic strip craniectomy (ESC) with post-operative helmeting is the gold-standard treatment for isolated, non-syndromic sagittal craniosynostosis in children under 6 months of age as it is has been demonstrated to reduce perioperative morbidity when compared to more invasive procedures such as cranial vault remodeling. ESC is frequently performed with or without the use of lateral osteotomies with technical selection being largely based on surgeon preference.
  • Previous studies have shown that there are no statistically significant differences in cranial expansion or complications between the two procedure variants; however, these studies are retrospective in nature and do not account for aesthetic outcomes.
  • The purpose of this study is to compare the efficacy of ESC with or without the use of lateral osteotomies in regard to cranial expansion and aesthetic outcomes for children treated with isolated, non-syndromic sagittal craniosynostosis. In addition, we seek to investigate if there are any observable changes in perioperative morbidity between the two procedures.
Read the detailed description
  • This prospective, randomized parallel study seeks to compare the efficacy of ESC with or without the use of lateral osteotomies in regard to cranial expansion and aesthetic outcomes for children treated with isolated, non-syndromic sagittal craniosynostosis.
  • Both arms of the study will undergo standard care throughout their participation which includes preoperative \& postoperative measurements of cephalic index using the STARscanner© (Orthomerica products Inc.), preoperative \& postoperative photographs, post-operative helmeting, and standard post-operative visits.
  • Additional research-related activities include chart review. Primary outcomes include degree of cranial expansion at 1 year post-operatively.
  • Secondary outcomes include aesthetic appearance at 1 year post-operatively (using a 5-point Likert scale) and a multitude of intraoperative clinical variables including estimated blood loss, instances of transfusion, instances of dural tear, instances of 30-day readmission, and instances of needing further surgery.

Study arms

  • Active comparator
    Endoscopic strip craniectomy with the use of lateral osteotomies

    Patients will have lateral osteotomies incorporated into their surgical procedure following suturectomy of the fused sagittal suture.

    Procedure: Endoscopic strip craniectomy (with lateral osteotomies) with post-operative helmet therapy

  • Experimental
    Endoscopic strip craniectomy without the use of lateral osteotomies

    Patients will NOT have lateral osteotomies incorporated into their surgical procedure following suturectomy of the fused sagittal suture.

    Procedure: Endoscopic strip craniectomy (without lateral osteotomies) with post-operative helmet therapy

Interventions

  • ProcedureEndoscopic strip craniectomy (with lateral osteotomies) with post-operative helmet therapy

    Endoscopic strip craniectomy is a surgical procedure performed to remove pathologic bone of the calvarium that includes the fused suture. Lateral osteotomies, also known as barrel-stave osteotomies, are performed by some surgeons because of their perceived benefit in regard to cranial expansion. Following surgery, orthotic helmet therapy is performed in order to mold the calvarium with the goals of optimizing contour.

What researchers measure

Primary outcomes

  1. Change in cephalic index from preoperative measurement to postoperative measurement at 1 year of age

    The cephalic index is the ratio of maximal head width and length. Patients enrolled in the trial will undergo pre-operative and post-operative measurement of their cephalic index using the STARscanner© (Orthomerica products Inc.). Patients will undergo measurement at recruitment and at 1 year of age.

    Time frame: Pre-operatively (at recruitment) & post-operatively (at 1 year of age)

Secondary outcomes

  1. Aesthetic outcome

    The aesthetic appearance of the calvarium will be measured by participating surgeons using a 5-point Likert scale (1-5) with 1 being extremely satisfied with aesthetic outcome and 5 being extremely dissatisfied with aesthetic outcome. Surgeons that are aware of the participant's assignment are excluded from this portion of the study to minimize bias.

    Time frame: post-operatively (at 1 year of age)

  2. Operative length

    Length of operation from incision to closure

    Time frame: during the intervention/procedure/surgery

  3. Estimated Blood loss

    Based on estimated volume of blood loss and perioperative changes in hemoglobin mass

    Time frame: during the intervention/procedure/surgery

  4. Instance of transfusion

    Whether or not the participant received a blood transfusion intraoperatively or post-operatively

    Time frame: during the intervention/procedure/surgery

  5. Amount of blood transfused

    Measured in mL/kg

    Time frame: during the intervention/procedure/surgery

  6. Instance of dural tear

    Whether or not the patient experienced a dural tear during surgery

    Time frame: during the intervention/procedure/surgery

  7. Instance of 30-day readmission

    Whether or not a patient was readmitted to the hospital for complications related to their surgical procedure

    Time frame: Day of procedure through 30 days post-operatively

  8. Instance of needing further surgical correction

    Whether or not the patient requires further surgical intervention to correct their calvarial defect.

    Time frame: 1 year after surgery

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 19, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
