Transconjunctival lower eyelid blepharoplasty with fat transposition above the orbicularis muscle for improvement of the tear trough deformity

Anatomical Basis for the Lower Eyelid Rejuvenation

BACKGROUND

The tear trough, hollow concavity of the lower eyelid, is one of the recognizable signs of facial aging. Anatomical description is essential in improving tear through deformity for facial rejuvenation.

METHODS

Fifty cadaver were microdissected. Fat pad types, fat herniation and the fibrous support system of lower lid were investigated. The areas of the fat compartments were compared using photogrammetry method and ImageJ software.

RESULTS

Lower lids develop palpebral bags as a result of herniation of orbital fat against a weak orbital septum in all cases (%100). The attachment of the arcus marginalis at the orbital edge is a large contributor to the middle-aged appearance of the midface in all cases (100%). The most common type is Type 1 (36%). In this type, three distinct fat pads were diverged by arcuate expansion at lateral, fascia of the inferior oblique muscle at medial, as central, medial and lateral. Type 2 specimens (20%) were observed with two fat pads. Double convexity contour is in Type 3 cases (%44). It is determined that the medial fat pads are located in larger areas. Also, herniation is particularly evident in the medial and mediocentral fat pads.

CONCLUSION

Analysis of the lower lid morphology enables surgeons to apply safe and effective procedures. The inferior oblique muscle and arcuate expansion structures should be supported and not be damaged during surgical interventions. Surgeons should focus mainly on the anatomical data obtained, and in this sense, surgeons apply them during aesthetic and reconstructive procedures of the lower eyelids.

Surgical Correction of Tear Trough Deformity (TTD) with Orbicularis Retaining Ligament Release and Volume Augmentation for Periorbital Rejuvenation: Review of the Literature

BACKGROUND

Tear trough deformity is a hallmark of periorbital aging. It is not, however, an exclusive feature of old age. While protruding orbital fat results in lower lid bags that are traditionally corrected by excision, correction of TTD can constitute a real challenge requiring volume enhancement in addition to addressing prolapse of orbital fat and descent of cheek tissues. Described therapeutic options include minimally invasive soft tissue augmentation with fillers or structural autologous fat transfer as well as invasive surgical procedures concomitantly with lower lid blepharoplasty or other facial rejuvenation procedures.

MATERIAL AND METHODS

Six eponyms have been used in the literature to describe the condition: (1) naso-jugal fold, (2) naso-jugal groove, (3) naso-jugal ditch, (4) tear trough, (5) tear trough deformity, and (6) tear trough depression. A separate PubMed database search of each of the 6 terms was conducted in addition to an advanced literature and systematic PICO searches to identify all described clinical retrospective or prospective, comparative or simple cohort studies related to surgical correction of TTD. An additional screening of references of retrieved clinical studies was performed to identify any missed reports.

RESULTS

A total of 435 publications were identified with the initial search. After excluding all none relevant studies, 44 papers were selected for review. 6 additional studies were identified by screening relevant references.

CONCLUSION

Almost all authors agree on the necessity to release the tear trough retaining ligament together with volume enhancement. Transconjunctival and transcutaneous incisions are reported. Most recommend repositioning of the protruding orbital fat for volume enhancement to mostly subperiosteal, or pre-periosteal pockets. Other reported options include pedicled buccal fat pad transposition, segmental fat grafting, and minced micrografts. Internal as well as external fixation of repositioned fat flaps have been described. Despite lack of solid objective evidence, several of these techniques when properly executed for the proper indication in selected patients are reported to result in a rewarding and long-lasting outcome. Unfortunately, it is difficult to determine the most appropriate technique that would universally yield the most pleasant and harmonious facial contour without creating an unnatural puffy appearance. It remains for the surgeon to identify the safe surgical approach that does not compromise lower eyelid function and achieves the most pleasing aesthetic outcome with the least complications and downtime.

Tear trough ligament reset as a new method for tear trough deformity and dark circles correction

Tear trough deformities and dark circles are important parts of periorbital aging. In this study, the tear trough ligament was reset to correct the tear trough deformity, and its effect on dark circles was analysed. The medical records of 60 patients who underwent eye bag plastic surgery between January 2021 and February 2022 were analysed (30 had traditional eye bag plastic surgery and 30 had the tear trough ligament reset). The tear trough deformity score and the dark circle score showed that the corrective effect on the tear trough deformity in the reset group was better than in the traditional surgery group at six-month follow up (mean (SD) tear trough rating scale (TTRS) score = 4.82 (0.95) vs 5.92 (1.00), p < 0.0001; L* value 55.27 (2.90) vs 47.51 (3.00), p < 0.0001). The satisfaction of patients in the reset group was significantly higher than it was in the traditional surgery group (25/30 vs 18/30, p = 0.045). Tear trough ligament reset is a safe and effective surgical method of periorbital rejuvenation, especially for beauty seekers with obvious tear trough deformities.

Lower Eyelid and Midface Rejuvenation: Suborbicularis Oculi Fat Lift

The lower eyelids and midface are considered to be a contiguous aesthetic unit although they are different anatomic structures. Through in-depth understanding of complex anatomy and aging theory and appropriate surgical strategies according to the type of aging, surgical outcome of aging lower eyelid/midface can be more and more predictable. This article discusses the characteristics and theories of aging and 5 types of lower eyelid/middle face aging based on 4 key factors, namely, protruding fat in the orbital, excess skin on the lower eyelid, sagging midface and soft tissue deflation. Various combinations of surgical strategies are adopted accordingly.
