The temporoparietal fascia consists of a thin layer of connective tissue. It measures some 2-3mm in thickness.
Relations The fascia unites anteriorly with the
orbicularis oris muscle, and the
frontalis muscle; it unites posteriorly with the
occipitalis muscle. Inferior to the
zygomatic arch, the fascia is continuous with the
superficial muscular aponeurotic system; both structures are continuous with the
platysma muscle of the neck, creating a single continuous fascial layer between the scalp superiorly and the clavicle inferiorly. The fascia is situated superficial to the
(deep) temporal fascia,''''
with an intervening layer of (sources differ) avascular loose connective tissue (the innominate fascia'') situated in the interval between the two fasciae; this structural arrangement of loose superficial layers and deep rigit layers confers a combination of mobility coupled with structural integrity to the region. The
superficial temporal artery and
vein, and the
auriculotemporal nerve course within or just deep to the temporoparietal fascia,'''''' and the frontal branch of the
frontal nerve (CN VII) courses within the fascia. == Clinical significance ==
