Tear trough deformity occurs for multiple reasons and at various ages depending on genetics, intrinsic, and extrinsic factors. When treating hollowness under the eyes it isn’t always easily fixed directly by placing fillers. There is usually a combination of midface volume loss and bone reabsorption due to age or a genetically inherited flat midface . When coming up with a treatment plan it is important to address the underlying structural causes of the problem instead of just the symptoms. In patients with good mid face projection and minimal under eye hollowing superior to the tear trough ligament but bellow the orbital rim, filler can be used sparingly in different planes to correct the deformity. This requires a thin filler that has the least hydrophilic effect such as belotero, classic Restylane, volbella, or vollure. These fillers vary in duration with the longest being around 1 year. Treatment of deeper tear trough deformity that may or may not include festoons or herniation of the suborbicularis oculi fat (SOOF) pad become much more complicated to treat with just filler alone, and can potentially be made worse by adding filler. Tear trough implants are a great option for these patients in combination with Implantech Flowers tear trough implants are a great option for these patients, especially in combination with other modalities. Implants have a longer longevity than filler and can be used on bone to correct moderate to severe loss of projection in the mid face thus supporting the tear trough ligament and correcting most deep tear trough deformities and naso-jugal grooves. With the additional treatment of festoons (malar edema) and herniation of the SOOF creating a bulge under the eye other procedures can be combined with the implant to provide total undereye restoration. These include removal of herniated fat pad, blephroplasty, CO2 laser for skin tightening, and soft tissue augmentation with microionized fat. As you can see, under eyes are a complex area to treat and there is no one size fits all. A consultation with a provider who can offer every treatment and is knowledgeable on the anatomy of this area is important.
