It is essential to localize the central sulcus in patients with lesions within or nearby the sensorial and/or motor cortex. The coronal suture is a valuable bony landmark in neurosurgical practice; it could be used to localize the central sulcus. There are scarce amount of literature about normal values of the distance between the central sulcus and the coronal suture. In the present study, the authors aimed to learn normative values of the distance between the central sulcus and the coronal suture in a patient sample representing Turkish population. The authors also aimed to look for any difference in values according to sex and age.


The authors retrospectively reviewed a prospectively collected database. Patients were evaluated on cranial computed tomography (CT) reformatted in 3 planes (axial, coronal, and sagittal). Intracranial and extracranial pathologies were scanned. If there was no pathology, the reviewed CT scan was added up to the database. The coronal suture and the central sulcus were identified at the midline location on axial and sagittal view CT images. Vertical distance between coronal suture and central sulcus was measured.


Mean distance of the central sulcus to the coronal suture was 47.5 ± 7.6 mm (range = 26.2–67.3 mm).


Identifying the central sulcus relative to the coronal suture is essential to preserve the primary motor and/or sensory cortices in neurosurgical procedures. The distance of the central sulcus to the coronal suture is approximately 4.7 cm in adult patients from Turkey, which did not differ according to age or sex.
