Fat management in upper blepharoplasty: Addition or subtraction blepharoplasties, how and when

BACKGROUND

As one of the most common aesthetic surgical procedures carried out today, blepharoplasty should be in the repertoire of every plastic surgeon. The term blepharoplasty encompasses a wide range of techniques and options that must be tailored to the specific defect and patient one has to treat. A sound knowledge of the upper and lower eyelids’ anatomy is essential for proper surgical execution. Trends have shifted towards more conservative methods (especially of the fat compartment) and sometimes in combination with augmentation techniques, helping to reach a rejuvenated appearance.

AIM

To present an overview of the surgical techniques considered for upper lid blepharoplasty and fat pad management, in addition to information on how a surgeon may approach the best treatment for his patient based on current publications in literature.

METHODS

We searched the literature published between 2013, to 2023 using Medline and Reference Citation Analysis. The database was searched using the keywords “upper blepharoplasty” AND “fat”. Papers without full text/abstracts and reviews were excluded. The search strategy followed the PRISMA. The American Society of Plastic Surgeons guidelines for Therapeutic Studies checklist was used to assess all articles. Two authors individually reviewed each article and rated them for importance and relevance to the topic. A consensus was sought and the most relevant studies.

RESULTS

After the application of the selection criteria used in our review, 13 publications were found to address upper lid blepharoplasty specifically. Three of these studies were reviews and three were retrospective studies. Five publications were comparative studies and a further two were clinical trials.

CONCLUSION

The tendency of modern surgery is to be conservative, by removing adipose tissue only if strictly necessary and restoring the volume of the upper eyelid in a concept of beauty that espouses a "full" sight. There is no gold standard technique to achieve younger and enhanced eyelids. Long-term prospective comparative studies are fundamental in understanding which path is the best to follow.

Traditional versus Laterally Extended Upper Blepharoplasty Skin Excisions: Objective and Patient-Reported Outcomes

BACKGROUND

Different skin excision shapes may result in different aesthetic outcomes after upper blepharoplasty.

METHODS

Two skin-only excision shapes were evaluated objectively and subjectively in 28 matched patients with laterally extended skin excision (group A) or traditional elliptical skin excision (group B). The pretarsal show, lateral eyebrow height, amount of scarring (evaluated with the Patient and Observer Scar Assessment Scale), and patient-reported aesthetic results (evaluated using FACE-Q) were scored and compared at 6 and 12 months postoperatively.

RESULTS

In both groups, pretarsal show improved significantly after blepharoplasty. The homogeneity of pretarsal show improved significantly in the lateral extension group (group A) together with slightly more pretarsal show (0.5 to 0.8 mm at central pupil region) at 6 and 12 months of follow-up compared with group B ( P = 0.004). A trend was observed in the exocanthion 45-degree measurement, in which group A had 0.6 mm greater pretarsal show 6 months postoperatively. Homogeneity of the pretarsal show had improved significantly in group A, but not in group B, at 12 months after blepharoplasty. No other significant differences were observed between the groups regarding pretarsal show measurements or FACE-Q scores. Both groups showed descent of the lateral eyebrow, but this was only significant in group B. Group B showed 1.4 to 2.0 mm more descent compared with group A. Scarring and adverse effects scores were low in both groups and did not differ.

CONCLUSION

Laterally extended skin excision and traditional elliptical skin excision both result in positive aesthetic results, but the laterally extended skin excision technique is accompanied by a slightly more favorable outcome.

Evaluation of upper blepharoplasty outcome-objective measurements and patients` satisfaction

Background/Aim. Upper blepharoplasty is one of the most often performed aesthetic operations and is indicated for periorbital rejuvenation or correction of some functional problems. The aim of the study was to evaluate the outcome of this procedure and to assess patients? satisfaction and possibilities of objective measurement of operative results. Methods. A two-year prospective observational study was conducted among female patients who had upper blepharoplasty done by the same surgeon. Data were collected from medical documentation, questionnaire, and objective measurements conducted via standardized digital photographs taken before and two months after surgery. Tarsal platform show (TPS) and brow fat span (BFS) were measured at three points (P1, P2, P3) before and two months after the surgery. A questionnaire conducted before surgery and two months after it included general complaints considering upper eyelids (visual field narrowing, fallen eyelids, the sensation of heavy eyelids, raising head backward in order to enhance vision, headache), patients? assessment of eyelid asymmetry and an additional questionnaire after surgery included questions for the surgeon and patients concerning satisfaction with treatment outcome. Results. This study involved 50 female patients aged be-tween 33 and 67 years (49.98 ? 8.6 years). There was a statistically significant difference in all points for TPS and BFS measurements before and after the operation. No significant asymmetries were noticed between eyes neither before nor after surgery. There was a statistically significant difference in operation success among 3 age categories in TPS-P1 (?2 = 13.089, df = 2, p = 0.001) and TPS-P2 (?2 = 8.386, df = 2, p = 0.015) with best results achieved in older patients (> 55 years). There was strong positive, statistically significant correlation between patient?s and surgeon?s satisfaction (r= 0.704, p = 0.002), as well as between patients? satisfaction and their age (r = 0.704, p = 0.002). Conclusion. Realistic expectations, adequate information about the surgery and possible complications, are essential to satisfied patients. Objective measurements correlate with patients? satisfaction and together with photographs can be a useful tool in communication with them.

A Prospective Randomized Study of Lateral Brow-Eyelid Complex Volume after Internal Browpexy Using Three-Dimensional Stereophotogrammetry

Background: A full lateral brow-eyelid complex may help rejuvenate and feminize the face. Objectives: To compare periorbital volume change of patients as measured by three-dimensional (3D) stereophotogrammetry before and after blepharoplasty with or without internal browpexy sutures. Methods: This is a prospective randomized controlled study of 124 eyelids of 62 adult female patients who underwent cosmetic upper eyelid blepharoplasty by a single surgeon. Subjects were randomized to blepharoplasty alone (control) or blepharoplasty with an adjunctive "brassiere suture" internal browpexy (intervention). An observer masked to the intervention measured the brow-eyelid volume using standardized images obtained with a 3D camera, before and after surgery. The minimum follow-up was 6 months postoperatively. Results: Sixty eyelids (30 patients) were treated with upper blepharoplasty alone and 64 eyelids (32 patients) had blepharoplasty plus internal browpexy. The mean volume gain was 0.85 mL in the internal browpexy intervention group and 0.19 mL in the control group. The volume increased in all patients receiving browpexy and this change was greater than after blepharoplasty alone (p < 0.05). The mean follow-up time was 16.8 months (range 6-24 months). Conclusions: Adjunctive internal browpexy during blepharoplasty was associated with increased volume of the lateral brow-eyelid complex.
