The Investing layer of deep cervical fascia is the most superficial part of the deep cervical fascia, and it encloses the whole neck.

Position

It surrounds the neck like a collar, it splits around the sternocleidomastoid muscles and the trapezius muscles. Posteriorly (towards the back of the neck), it blends with ligamentum nuchae.

Anteriorly, it is attached to the hyoid bone. Superiorly, it attaches to the lower border of mandible, to the mastoid process, superior nuchal line and the external occipital protuberance.

Between the angle of the mandible and the tip of mastoid process it is strong and splits to enclose the parotid gland. The superficial parts extend superiorly as the parotidomassetric fascia and reaches the zygomatic process. The deepest part extends to the base of the skull, between the temporal styloid process and the angle of mandible is thickened to form the stylomandibular ligament. Inferiorly, the investing layer of deep cervical fascia is attached to the spine and acromion of the scapula, the clavicle with trapezius muscle, the clavicle and manubrium of the sternum with sternomastoid muscle.

It is considered by some sources to be incomplete^[1] or nonexistent.^[2]
