2. DEEP CERVICAL FASCIA
(FASCIA COLLI)
lies under cover of the Platysma, and
invests the neck and fills up the interval
between muscles, vessels and cervical
viscera.

3. DEEP CERVICAL FASCIA
It is condensed to form
1) Investing Layer
2) Pretracheal Layer
3) Prevertebral Layer
4) Carotid Sheath
5) Buccopharyngeal Fascia
6) Pharyngobasilar Fascia

8. Investing Layer
Attachments

14. Tracings
Horizontal extent

15. Vertical extent

18. Suprasternal space (Space of
Burn’s)

19. Supraclavicular space

20. To sum up
 Encloses 2 muscles – trapezius,
sternomastoid;
 Encloses 2 glands – submandibular &
parotid;
 Encloses 2 spaces – suprasternal &
supraclavicular;

21. Forms roof of 2 triangles – anterior & posterior;

22. Thicken twice to form parotido-
masseteric fascia and stylomandibular
ligament.

23.  Forms 2 fascial slings for omohyoid
and diagastric;

24. Gives origin to 2 fascial processes –
pretracheal & prevertebral fasciae.

Buccopharyngeal Fascia

36. Applied Anatomy
1.Collection of pus beneath parotido-masseteric
fascia => severe pain

37. 2. Pretracheal fascia which covers the posterior
surface of thyroid gland, is ill defined or thin
enlargement in post. direction
compression of oesophagus

38. 3. Thyroid moves with deglutition.
4. In block dissection of neck during removal of deep cervica
lymph nodes, frequently exposes carotid sheath.
5. While excising the submandibular salivary gland, the exte
carotid artery should be secured before dividing it, otherwi
it may retract through the stylomandibular ligament and ca
severe bleeding.

39. 5. Collection of pus in retropharyngeal space.

41. 6. Collection of pus in lateral pharyngeal space.

42. 7. Collection of pus in behind prevertebral fascia.
