Facial fat compartments as depicted by routine MRI. a – d. Axial T2 W slices. e. Sagittal T2 W image through the mid-pupillar line. f – g. Coronal T2 W slices. For easier correlation with the schematic drawing shown in fig. 1, the same numbers were used for the superficial and deep facial fat compartments. Fat compartments: nasolabial fat (1), medial superficial cheek fat (2), middle superficial cheek fat (3), lateral temporal cheek fat (4), paramedian forehead fat (6), superior orbital fat (7), inferior orbital fat (8), lateral orbital fat (9), superior jowl fat (10), inferior jowl fat (11), medial sub-orbicularis oculi fat (12), deep medial cheek fat (14), buccal fat pad (15). Muscles and other relevant structures: depressor anguli oris muscle (DAOM), frontalis muscle (FM), levator labii superioris and levator labii superioris aleque nasi muscles (LLSM), platysma muscle (PM), orbicularis oculi muscle (OOCM), orbicularis oris muscle (OOM), superficial musculoaponeurotic system (SMAS), Stensen’s duct (SD), zygomaticus minor and major muscles (ZM)
