The important aesthetic landmark of the upper third is the nasion, defined as the suture between the frontal and nasal bones in the midsagittal plane. Together with the nasion, the glabellar angle (the line connecting the maximal glabellar prominence with the nasofrontal suture, as compared to the horizontal or nasal-sellar line) is used as an anthropometric measurement in facial and cephalometric analysis.

Shifting from the base and back of the skull to its front, the frontal bone includes the following landmarks and structures: glabella, the superciliary arch, supraorbital notch (foramen), foramen cecum, orbital surface, lacrimal fossa, and supraorbital margin (Plates 3.7a and c, 3.8a and c, and 3.12). The junction between the frontal bone and the nasal bones is called the nasion. The roof of the skull grows rapidly during fetal stages and, in humans, for several years after birth. This rapid growth is necessary to accommodate the extensive increases in brain size as neurons mature and become myelinated. The frontal suture or metopic suture (meaning “among”) is the suture between the two frontal bones and is usually closed in the adult but palpably open in a newborn human baby, which helps the infant’s head to safely compress to ease its movement through the birth canal.

First, identify the nasion on the front of the face. Nasion is the depressed area on the top of the nose and between the eyes where it meets the frontal bone (Figure 6.2). Second, identify the inion at the backside of the lowermost part of skull. Run your finger from the back of head towards the neck in the median plane. You will feel a protuberance here. This is the inion (Figure 6.3). Using a non-elastic measuring tape, measure the distance between these two points. Suppose this distance is 34 cm. Now, calculate the following:

In addition, we also analyzed the preoperative and postoperative differences by measuring four linear nasal datasets and three angle datasets. Linear data were measured as follows: nasal length (straight-line distance between root point and tip point), nasal height (straight-line distance between root point and subnasal point), nasal width (distance between outermost points on both sides of alar), and nasal depth (straight-line distance between the subnasal point and tip point). Nasolabial angle (angle between the columella line and the line connecting the subnasal point and the upper lip point), nasofrontal angle (angle between the nasal dorsum line and the oblique plane from the forehead to the nasion), nasal tip angle (angle between the nasal dorsum line and columella line) [7].

Testing was done in two phases: MT determination and the experiment proper. Participants were first fitted with a tight Lycra swim cap. Using the 10/20 International system for EEG electrode placement, three experimental positions were marked: Precuneus (PZ), MPFC, and Supplementary Motor Area (SMA). Since SMA and PZ have been shown to have no effect on self-enhancement bias [13, 35], these areas were selected for comparison. CZ was also marked for control purposes. MPFC was marked at 1.5 cm anterior to one-third of the distance of nasion to inion. SMA was marked at 3 cm posterior of one-third the distance of nasion to inion. These regions were identical to those previously used [13, 14]. Participants wore protective earplugs during stimulation to prevent transient threshold shifts caused by exposure to the acoustic artifact generated by the discharge of the TMS coil [36].
A superficial nasal dermoid cyst excised through a novel horizontal zig-zag incision in a 49-year-old man

A 49-year-old man, who was a previous boxer and otherwise healthy, presented with a significantly swollen lump over the nasion (junction of the frontal and nasal bones inferior to the glabella). Despite this, he presented without fever or evidence of infection. Twenty years ago, he received a punch to the nose and since then has had a recurrent lump that appeared at this site. A sample of fluid from the cyst was obtained and revealed a mucous-like aspirate without cells. Computed tomography of the facial skeleton revealed a 25-mm encapsulated cyst. Within the frontal suture, a small cavity was seen with an open foramen caecum (Figure 1(A)). Magnetic resonance imagery revealed that the cyst was in its entirety extracranial (Figure 1(B,C)). An initial zig-zag incision in the skin was made at the nasion (Figure 2(A)). Blunt dissection was used to free the cyst from the soft tissues (Figure 2(B)) and a periosteal elevator was used to free the cyst from the bone. Although a fibrous cord was seen attached to the cyst, there was no evidence of intracranial extension or engagement of muscle, nerve or vessels (Figure 2(C,D)). The incision was closed with subcutaneous sutures (Vicryl 4/0) and the skin with Vicryl Rapid 6/0 (Figure 2(E)). Postoperative histological analysis revealed a cystic structure with evidence of chronic inflammation and lymphocyte infiltration. The cyst was radically removed and there was no indication of malignancy.
