A limit of our Beauty Arch is to focus it on the analysis of the profile, without allowing the
assessment of the transversal measure of the zygomatic region in frontal plane.
In Literature several techniques of malar augmentation have been described and classified into two
groups: osteotomic techniques and grafts placements.
The former include: 1) the "Lamellar split osteotomy" described by Salyer KE (10) with the purpose
of obtaining an antero-lateral augmentation of the cheekbone; 2) the Zigomatic Sagittal Split
Osteotomy or ZSSO described by Gasparini et al.(11) that allows for correction and stabilization of
the midface without the use of distraction devices; 3) Sandwich Zygomatic Osteotomy introduced by
Mommaerts et al.(12), which consists in the anterior and lateral dislocation of the zygomatic bone
after the vertical and oblique-horizontal osteotomy, 4) Le Fort III Advancement of the midface (13),
which has been widely codified and has been applied for decades to correct the hypoplasia of the
middle third of the face. However, it implies the movement of the median nasal region, which
sometimes is not necessary in patients affected by non-syndromic malformation. In addition, the
invasiveness of the technique restricts its application to patients with severe hypoplasia.
Among the techniques exploiting the use of grafts, several autologous, heterologous and alloplastic
materials to increase the projection of the zygomatic region have been proposed. Silicon, Proplast
and Supramed (15,16,18,23) do not represent good choices because of their frequent complications such
as: formation of foreign body granulomas, displacement of the implant, and post-operative infective complications.
Autologous bone graft is an excellent material, but has the not negligible drawback of the donor site
morbidity. In our study we have used Medpor implants of different size depending on the
characteristics of the zygomatic hypoplasia. Medpor has proven to be a highly biocompatible
material. Futhermore, the firm nature of this material allows a simple modeling and adaptation to
the underlying tissues. Because of the white color, Medpor implants are not visible through the
overlying tissue; the surface is rough in order to facilitate its anchoring to the tissue in the desired
position.
