PURPOSE: In a previous cadaveric work, we identified and described useful and
reproducible surface skin landmarks to lateral sulcus, central sulcus and
preoccipital notch. Potential limitations of this cadaveric study have been
raised. Thus, the objective of this study was to confirm radiologically the
accuracy of these previously described surface skin landmarks on brain magnetic
resonance imaging (MRI) of healthy subjects.
METHODS: Healthy adult volunteers underwent a high-resolution brain MRI and
measurements of the orthogonal skin projection (OSP) of the anterior sylvian
point (AsyP), the superior Rolandic point (SroP) and the parietooccipital sulcus
were made from nasion, zygomatic bone and inion, respectively. These measures
were compared to our previous cadaveric findings.
RESULTS: Thirty-one healthy volunteers were included. ASyP was 33 ± 2 mm above
the zygomatic arch, and 32.3 ± 3 mm behind the orbital rim. The lateral sulcus
was 63.5 ± 4 mm above the tragus. The SRoP was 196.9 ± 6 mm behind the nasion.
The superior point of the parietooccipital sulcus was 76.0 ± 4 mm above the
inion. These measurements are comparable to our previously described cadaveric
findings.
CONCLUSION: We here described three useful, simple and reproducible surface skin
landmarks to lateral, central and parietooccipital sulci. Knowledge of these
major landmarks is mandatory for Neurosurgical practice, especially in an
emergency setting.
