[2] The temporoparietal fascia consists of a thin layer of connective tissue.
[2] The fascia is situated superficial to the (deep) temporal fascia,[1]: 357 [2] 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.
[2] The superficial temporal artery and vein, and the auriculotemporal nerve course within or just deep to the temporoparietal fascia,[1]: 357 and the frontal branch of the frontal nerve (CN VII) courses within the fascia.
[2] The temporoparietal fascia can serve as a donor tissue for reconstructive surgery.
It affords reliable flaps with good blood supply when the tissues of the region are intact (however, prior lesions to the region may compromise the blood supply of the tissues; creating flaps from such compromised tissue is contraindicated due to a risk of subsequent ischaemic necrosis of the flap).
