[Clinical application of orbital fat autograft for tear trough deformity through tranconjunctival approach].

[OBJECTIVE] To discuss the orbital fat autograft for lower baggy eyelid with tear trough deformity and its therapeutic effect through tranconjunctival approach.

[METHODS] The patients with lower eyelid bag and tear trough deformity were included into the study. The included 32 patients met the following criterias: ①less than 40 years old;②lower eyelid skin was not relaxed;③less than 1 s in Snap test; ④ Hirmand type Ⅰ and Ⅱ. They were treated with tranconjunctival lower blepharoplasty combined with the tears ligament relaxation. The orbital fat was repositioned on the depression site above orbital periosteum to correct tear trough deformity. The effect was evaluated through Tear Trough Rating Scale (TTRS) and satisfaction degree.

[RESULTS] Three cases with Hirmand type Ⅱ didn't have good effect. Among them, the baggy eyelid was corrected in 2 cases, while the tear trough deformity need additional hyaluronic acid injection. One patient underwent secondary lower blepharoplasty through cutaneous incision. Good effect was achieved in the other 29 cases with no depression deformity and eyelid withdrawal. The TTRS scores 6 months after operation was significantly improved(P ＜ 0.01).Satisfaction degree was 100％ (14/14) and 83.3％ (15/18) in type Ⅰ and Ⅱ patients.

[CONCLUSIONS] The technique can simultaneously improve lower eyelid bag and the tear trough deformity. It can be applied in periorbital rejuvenation for middle-aged and young patients.
