Thyroid 101. Located above the Adam's apple, your thyroid produces thyroid hormone (TH), which regulates, among other things, your body's temperature, metabolism, and heartbeat.

Background. Festoons of the eyelids are redundant folds of lax skin and orbicularis muscle of the upper or lower eyelids that hang, in hammocklike fashion, from canthus to canthus when the face is upright. Malar mounds are discrete soft tissue convexities that protrude from the lateral part of the malar eminence.ites of festoons include (A) upper lid, (B) pretarsal, (C) preseptal, (D) orbital, (E) malar, and (F) cutaneous dewlap (no muscle). For split-level flaps, the outer face of the orbicularis is exposed by elevating a skin-only flap. The orbital septum and intraorbital fat are exposed by elevating a skin-muscle flap.
