A medial sulcus just lateral to the nasal pyramid, which extends distally for 2.5 cm obliquely towards the angle of the mandible, has been termed a ‘nasojugal’ sulcus or ‘tear trough.’7‘8 However, either by heredity or mainly with aging changes, this suborbital depresÂsion continues beneath the entire lower eyelid. This volume deficiency is not at the level of the inferior orbital rim as originally thought by plastic surgeons. Instead, it occurs consistently at a measured distance of 8 to 10 mm below the orbital rim. This observation was made by me early in the 1980s, when postoperative blepharoplasty patients began complaining about their more tired, ‘hollow’ look.
The etiology of why such a depression in this area appears as early as the third decade of life and certainly by the late 40s and early 50s has been unclear. Recently, however, largely through the photographic and comÂputer studies of Lambros,4 it is now agreed upon that a true atrophy or involution of fat occurs in the upper two-thirds of the face and largely in the periorbital region. This disappearance of fat correlates with the increased appearance of a suborbital hollowness, which creates a tired, haggard appearance.
When indeed, as in many instances, weakening of the orbicularis oculi muscle and orbital septum occurs, perÂmitting the intraorbital fat to protrude forward into what has been commonly called ‘fat bags,’ the suborbital hollow sulcus is accentuated even further. Ambient light creates a highlight on the top of the fat bag ‘mountains’ while a shadow is created in the suborbital ‘valley.’ The juxtaposiÂtion of the positive and negative contours enhances the tired ‘ring’ appearance at the lid-cheek junction.
