This study is designed to test the hypothesis that neuronavigational system-guided transcranial magnetic stimulation has higher accuracy for targeting the intended target as demonstrated by eliciting a greater degree of virtual aphasia in healthy subjects, measured by delay in reaction time to picture naming.
FAQs
Its main value is consistency: the nasion provides a stable midline reference from which clinicians can establish facial planes and calculate cranial or facial measurements. Because these assessments depend on positional relationships, accurately locating this point helps characterize facial proportions and supports comparisons within cephalometric, anthropometric, and clinical evaluations.
Identification can combine surface examination, palpation, and medical imaging. Surface assessment and palpation help locate the frontonasal suture externally, while radiographs or three-dimensional scans provide an image-based reference. Using these approaches to confirm the same midline point improves landmark placement before measurements or treatment planning are performed.
In cephalometric analysis, the nasion serves as a reference point for organizing cranial and facial measurements. Its location helps establish planes and evaluate facial proportions in a structured way. The resulting measurements can contribute to orthodontic assessment and provide anatomical information relevant to maxillofacial planning.
A typical workflow begins by locating the midline landmark through surface examination or palpation, then confirming its position with medical imaging when needed. Clinicians can use the identified point to establish facial planes and calculate relevant cranial or facial measurements. Accurate placement is important because later interpretations depend on that reference.
Radiographs and three-dimensional scans help clinicians interpret the nasion as an image-based anatomical reference. These modalities can support identification of its position when assessing craniofacial structure and can be used alongside surface examination or palpation. The documented landmark then assists with measurements, facial proportion assessment, and planning decisions.
The landmark is useful when clinicians need a consistent reference for orthodontic evaluation, maxillofacial planning, or reconstructive and corrective procedures. Its position supports assessment of facial proportions and helps organize cranial or facial measurements. It also contributes to anthropometric studies, where standardized anatomical references are needed for structured analysis.
