However, it is questionable whether the same strategies can always be used for Caucasian and Japanese patients, owing to differences in bone and skin structures and epithelial thickness.<\/jats:p><\/jats:sec>Aims<\/jats:title>To assess a novel classification system and treatment algorithm for correcting tear trough depressions and eye bags in Japanese patients.<\/jats:p><\/jats:sec>Methods<\/jats:title>Tear trough depressions can be classified into three types according to the presence or absence of a \u201cnegative vector\u201d based on retrusion of the maxilla relative to the anterior corneal surface, with or without eye\u2010bag protrusion when smiling. Type 1 patients (without the negative vector) can be treated simply by filling the depression in the tear trough and the palpebromalar groove region. Type 2 patients (with a negative vector and no eye\u2010bag protrusion on smiling) also require volume restoration in the mid\u2010cheek (deep medial cheek fat, suborbicularis oculi fat, and pre\u2010maxillary space); this not only enables volume recovery but also compensates for maxillary deficiency. Type 3 patients (with a negative vector and eye\u2010bag protrusion on smiling) require an additional step, based on placing a filler in front of the eye bags and pushing orbital fat backward.<\/jats:p><\/jats:sec>Results<\/jats:title>Case presentations demonstrate the utility of the techniques involved.<\/jats:p><\/jats:sec>Conclusions<\/jats:title>This system provides a simple and practical method for classifying and treating Japanese patients with tear trough depressions and eye bags.
