Loss of volume in the temple can result in a gaunt, wasted appearance. Dermal filler augmentation of the temples can counteract
volume loss and achieve a more balanced and youthful appearance. Although the temporal fossa is a critical area for volume restoration
of the aging face, published information is limited. The authors retrospectively describe the treatment of 20 female patients who
sought facial rejuvenation and received small gel particle hylauronic acid (SPG-HA) injections for temporal fossa augmentation. The
authors discuss a rationale for their choice of dermal filler and provide a detailed, illustrated injection technique guide for restoring
volume in the temporal fossa region with SPG-HA. There is a need for prospective, controlled studies investigating safety, efficacy
and persistency of hyaluronic acid fillers in this area of the face.

Age-associated facial changes are a result of thinning
of the epidermis, atrophy of subcutaneous fat layers,
structural changes of the bones, loss of elasticity and
weakening of underlying muscles.1 Soft tissue augmentation
with injectable dermal fillers has become a standard treatment
option for patients seeking aesthetic improvement of these
changes throughout the face. Dermal fillers have been used primarily
in treating the nasolabial folds. In recent years, however,
the aesthetic field has come to appreciate their value in treating
the lateral face, including the temporal fossae, to obtain a more
Loss of volume in the temple can result in a gaunt, wasted
appearance. This area of the face may not be as obvious as
other facial folds or wrinkles, and may be overlooked by the
patient and provider. Dermal filler augmentation of the temples
can alter the upper and midface and achieve a more balanced
and youthful appearance. When discussing treatment options
for managing volume loss in the aging face, the medical
aesthetic provider should consider the potential benefit of
temporal fossa augmentation with dermal fillers.
Although the temporal fossa is a critical area for volume
restoration of the aging face, there is limited information in the
literature pertaining to this topic and even less information on
how one may approach injection in this area. The purpose of
this article is to review the authors' experience using SGP-HA
for augmentation of the temporal fossa area and to provide a
detailed injection technique guideline.
Background: Applied Anatomy
Soft-tissue augmentation with SGP-HA is considered a safe
procedure associated with minimal to no downtime for the
patient. To achieve optimal results and limit the potential for
adverse events, the injector must have appropriate knowledge
of the applied anatomy. Therefore, the anatomic layers of the
forehead and temple, as well as the various planes for safe
injection of fillers will be discussed. The temporal fossa is a
shallow depression on the side of the skull bounded by the
temporal lines and terminating below the level of the zygomatic
The boundaries of the temporal fossa are as follows:
Medial: Os frontale, os parietale, os temporale, os
sphenoidale, os occipitale (bones of neurocranium).
Lateral: The temporal fascia and overlying skin
Anterior: Posterior surface of the frontal process of the
zygomatic bone and the posterior surface of the zygomatic
process of the frontal bone.
Superior: Pair of temporal lines that arch across the skull
from the zygomatic process of the frontal bone to the
supramastoid crest of the temporal bone.
Inferior: Zygomatic arch laterally and by the infratemporal
crest of the greater wing of the sphenoid medially.
The temporal fossa contains the temporalis muscle and layered
fascia, the superficial, middle and deep temporal vessels and
the temporal branch of the facial nerve2 (Figure 1).
