. Cunningham's Text-book of anatomy. Anatomy. THE NECK. 1387 with the carotid sheath and its contents, being retracted well forwards. In approach- ing the trunk of the inferior thyreoid artery from the front the sterno-mastoid and carotid sheath are retracted backwards and the dissection is continued through the cellular interval between it and the sheath (outer capsule) of the thyreoid gland, which is formed by the splitting of the pretracheal fascia. A glandular abscess in this compartment usually points upon the surface, adhesions being formed, first, between the gland and the fascia, and, subsequently, between the latter and the cutaneous structures. In diffuse suppurative cellulitis of this compartment the pus burrows towards the root of the neck, and may reach either the mediastinum or the axilla.
