“…Although brain wrinkles become more visible in imaging techniques such as MRI [5][6][7][8][9][10][11][12][13][14], they sometimes have inaccuracies [15][16][17][18][19]. Furthermore, recognizing them during surgery is very difficult due to being covered by vessels and arachnoid and small accessible space to the brain surface [20].…”

Background and Aim: In the present study, the cerebral surface landmarks in human fresh autopsy specimens were investigated. Methods and Materials/Patients: Totally, 37 fresh adult autopsy human brain specimens from the Rasht Forensic Medicine Center were enrolled. Four specimens were excluded because of some traumatic injuries to cerebral cortex. Demographic information of all cases was obtained. Length of bilateral central sulcuses and posterior ramous of Sylvian fissures, thickness of superior, middle, and inferior gyri of temporal lobes, as well as the distance from frontal poles to midpoint of central sulcuses were measured and analyzed using SPSS software. Results: In total, 25 male (75.8%) and 8 female (24.2%) specimens were included. Mean (range) length of posterior ramus of right and left Sylvian fissure were 75.61 (50-95) and 74.55 (49-100) millimeter, respectively. Mean (range) length of right and left central sulcus were 94.85 (75-115) and 97.24 (65-125) millimeter, respectively. Mean (range) thickness of right and left superior temporal gyrus were 16.66 (5-20) and 15.33 (7-25) millimeter, respectively. Mean (range) thickness of right and left middle temporal gyrus were 16.63 (5-25) and 16.42 (8-25) millimeter, respectively. Mean (range) thickness of right and left inferior temporal gyrus were 10.30 (5-20) and 10.70 (5-22) millimeter, respectively. Mean (range) distance from right and left frontal pole to midpoint of right and left central sulcuse were 81.27 (55-105) and 82.63 (60-105) millimeter, respectively. There were no statistically significant differences between two hemisphere measurements. Conclusion: It can be said that the two hemispheres are similar in cerebral surface landmarks.

These sulcal and gyral key points can be particularly useful for initial intraoperative sulci identification and dissection. Together, they compose a framework that can help in the understanding of hemispheric lesion localization, in the placement of supratentorial craniotomies, as landmarks for the transsulcal approaches to periventricular and intraventricular lesions, and in orienting the anatomic removal of gyral sectors that contain infiltrative tumors.

Background: Intracranial convexity lesions are poorly defined by recognizable anatomical landmarks. Even in expert hands, exact localization of small subcortical lesion and its projection to the skull is sometimes unreliable and can cause potential surgical complications. In this report, a simple and handy technique for localizing superficial intracranial lesions on the scalp under computed tomography (CT)-scan guidance is described. Methods: This technique, HeaDax, is based on using extracranial landmarks. We constructed an isosceles square triangle with three pieces of copper electrical wire and placed it on the skin scalp. Then, we took a CT-scan but without the need of the classic head reference planes (e.g., orbitomeatal or along the orbital roof). Results: For the measurements, we need to have the intracranial lesion located on the CT slice with respect to the two landmarks which are the height and hypotenuse of the triangle. The promising preliminary results of HeaDax applied to a phantom skull model encourage us to use it successfully for our first patient presenting a right subcortial supramarginal retrorolandic cavernoma. Conclusion: HeaDax procedure is a good alternative for localizing superficial intracranial lesions on the skin scalp under CT-scan or magnetic resonance imaging guidance. It can be used as a substitute when stereotactic and neuronavigation systems are not easily available, especially in developing countries and in resource-limited environments. HeaDax has a true potential for further developments and applications in cranial surgery.
