The term "glabella" in cephalometric reference pertains to which point?

The term "glabella" specifically refers to the most prominent point of the frontal bone located between the eyebrows, just above the nasion. This area is anatomically significant in cephalometric analysis as it helps establish the midline and assess the relationship between various cranial structures. The prominence of the glabella can provide insights into the overall facial profile and is important in orthodontic and surgical assessments.

In contrast, the most anterior point of the fronto-nasal suture pertains to a different anatomical landmark that is less commonly used as a reference point in cephalometrics. The deepest concavity in the maxillary area refers to an anatomical feature related to the maxilla but does not specifically denote the glabella. The anterior nasal spine is a distinct landmark located at the base of the nasal septum and is not associated with the frontal bone prominence. Understanding the unique definitions and locations of these terms helps clarify their function in cephalometric analysis.
