The area superior to the radix is called the glabella (nasion), which extends from the inner margin of the bilateral eyebrows to the horizontal line of the upper eyelid, and it is similar to a pentagon. In the lateral view, there is an indentation at the glabella before it connects with the starting point of the nasal bridge, which is called the nasofrontal angle, as a referential point of rhinoplasty, with the standard range at approximately 120–130° among Orientals. Common rhinoplasty does not intentionally augment the glabella to avoid making the nasal bridge exceedingly straight or the nasofrontal angle shallow, leading to an unnatural appearance such as a lion nose (like the nose of Namry). However, some patients may have excessive depression at the starting point or radix of the nasal bridge, with the nasofrontal angle less than 110°, and even a saucer-shaped depression at the glabella till the forehead, which undermines the smooth connection between the nasal bridge prosthesis and glabella or the naturalness of the radix after rhinoplasty or even limits the selection of the size and height of nasal implants. Therefore, the height of the glabella is also adjusted along with open (Korean-style) rhinoplasty, which is also called three-section rhinoplasty. Surgical conditions comprise the augmentation of the glabella (radix) with a flaky Gore-Tex or auricular cartilage, augmenting the nasal bridge with artificial nasal implants and sculpting the nose with an autologous nasal septal or auricular cartilage.
Similar to the common open rhinoplasty, glabellar augmentation is conducted via an incision at the nasal columella and emplacing the Gore-Tex at the glabella before other rhinoplasty procedures. If the patient only needs glabellar augmentation without rhinoplasty, the direct emplacement of Gore-Tex via a 0.5-cm incision at the inner margin of the bilateral eyebrows is also considered. In addition to surgical intervention, a non-surgical method is employed to augment the glabella, such as the injection of autologous fat or hyaluronic acid and even long-acting Aquamid, which obtains the similar results as surgery.
