CT-Scan Images of The Posterior Orbital, Orbital Apex, Extraocular Muscles Positions and Axes in Craniosynostosis

Craniosynostosis is the premature and pathological fusion, either partial or complete, of one more cranial sutures. One ophthalmological complications strabismus (in 39–76% cases), with severe manifestations in syndromic craniosynostosis. Head-CT 3D-reconstruction can be used to evaluate anatomical abnormalities orbital aspects assist clinicians planning surgery. Materials Methods: A retrospective descriptive–observational study was conducted for 43 patients period from January 2017 March 2022. The had non-syndromic craniosynostosis underwent head CT-scans at Dr. Soetomo General Hospital, Surabaya. posterior bones, apexes, positions axes extraocular muscles were evaluated by an neuroimaging radiology consultant. Results: 26 male subjects (60.5%) 17 female (39.5%) evaluated. 18 (41.9%) normal configurations muscles, 4 (9.3%) showed mild abnormalities, 13 (30.2%) moderate 2 (4.7%) moderate–severe 6 (11.6%) seesaw pattern abnormalities. 33 (76.7%) apex configurations, 3 (7%) ballooning ethmoidal sinuses, protrusions lateral wall (greater sphenoid wing), 5 combined sinus protrusion wall. Conclusion: smallest excyclorotation observed configuration right eye (4.5–11.3°) left (3.6–7°). greatest noted (7.6–21.4°) (7.4–30°). incyclorotated axis excyclorotated axis, a greater degree pattern.
