AI Article Synopsis
- The treatment of tear troughs, or the medial infraorbital region, is gaining popularity due to its minimally invasive nature and the use of soft tissue fillers injected with a cannula.
- In a study involving 123 participants, the clinical outcomes were evaluated six months after injecting an average of 0.26 cc of filler per tear trough, showing significant improvements in depth, hyperpigmentation, fat pseudo-prolapse, and wrinkle severity (all p < 0.001).
- The findings suggest that this injection technique is effective for reducing the appearance of hollowing under the eyes with few adverse effects, using a method that emphasizes bridging gaps rather than filling completely.
Article Abstract
Background: The treatment of the medial infraorbital region also termed the tear trough has become increasingly popular by the use of soft tissue fillers in a minimally invasive approach using a cannula.
Methods: A total of 246 tear troughs were injected and investigated originating from 123 study participants. The clinical outcome was evaluated 6 months after the treatment by independent observers based on standardized frontal images and the procedure was documented by ultrasound imaging.
Results: On average, 0.26 (0.1) cc [range: 0.08-0.32] of soft tissue filler material was injected per tear trough. Tear trough depth was before the treatment rated as 2.12 (0.4), whereas after the treatment it was 1.15 (0.4) (p < 0.001). Hyperpigmentation score was 2.19 (0.4) before the treatment, whereas after the treatment it was 1.31 (0.5) (p < 0.001). Intraorbital fat pseudo-prolapse severity was rated before the treatment 1.88 (0.7), whereas it was rated after the treatment 1.14 (0.3) (p < 0.001). Wrinkle severity of the lower eyelid was rated before the treatment 1.51 (0.6), whereas it was rated after the treatment 1.12 (0.3) (p < 0.001).
Conclusion: The results of this retrospectively investigated case series revealed that the conducted injection technique for treating the tear trough for medial infraorbital hollowing with a cannula provided statistically significant clinical improvement with a limited adverse events profile. The technique utilized an injection approach which was perpendicularly oriented to the longitudinal axis of the tear trough thereby "bridging the gap instead of filling the entire valley."
