A, The lateral (superficial) surface of the superficial parotid is invested by the parotid fascia
(arrows), which is contiguous with the masseter fascia and forms an oncologic barrier.
The flap was sutured to remnant parotid fascia and masseteric fascia avoiding a direct or indirect hitch or compression on the branches of the facial nerve.
Careful placement of sutures attaching the flap to the remnant parotid fascia was the most important step.
The ligaments of the pericardium are often attached to the mandibles and parotid fascia
cranially, and to the first rib or manubrium caudally" Al Qasemi added.
In this region, the SMAS was different from the parotid fascia, being thick [1,18] or thin [4,12,14,19] and, moreover, separated from the parotid fascia by a thin lamina of deep adipose tissue .
In the parotid region, the platysma muscle and the SMAS are separated from the parotid gland capsule propia by connective tissue, the anlage of the parotid fascia. Superficial to the platysma muscle and the SMAS, the anlage of the superficial adipose layer with fibrous septa is observed (Figures 8(b) and 8(c)).
Regarding the parotid region in adults, it has been reported that the parotid fascia corresponds to the SMAS [16, 33].
 studied serialised cross sections of 10 human fetuses and found no structure that might be considered to constitute the parotid fascia. Our findings indicate that the lower part of the parotid region is enclosed by the platysma muscle, while the upper part of the parotid region is enclosed by the anlage of the SMAS.
A thick sub-SMAS (superficial musculoaponeurotic system) flap external to the parotid fascia
is elevated as far anteriorly as required.
Anatomically, the SMAS lies directly over the parotid fascia
, and it is therefore usually resected along with the parotid gland.
The posterior border of the superficial part is separated from the parotid gland by the stylomandibular ligament, which is the thick part of the parotid fascia
. The upper part of the lateral surface is in contact with the submandibular fossa of the mandible and the medial pterygoid muscle below the mylohyoid ridge.
Immediate surgical debridement with wide local skin excision down to the level of the parotid fascia
revealed necrotic parotid tissue.
