With consideration of variable presence and location of the supraorbital notch and foramen, analysis of computed tomography scan may be beneficial in preoperative planning of foraminotomy and fascial band release in adult patients with migraine to prevent intraoperative complications, a new study found. Researchers conducted the study retrospectively on computed tomography images of 70 migraine and 70 control patients. Presence and nature (foramen or notch) of exiting points of neurovascular structures in terms of side and gender in both groups and the distances of these structures to the midline of the face were evaluated. Among the findings:
- In migraine and control groups, the most commonly seen structure was single notch.
- Coexistence of foramen and notch was statistically significant in migraine and female migraine groups than control and female control groups.
- In all case, foramen-midline distance was statistically significant longer than the notch-midline distance.
- In migraine patients, no statistically significant difference was detected regarding distances of foramen and notch to midline in terms of side and gender.
