Algorithmic Approach to Lower Lid Blepharoplasty

An Overview of Surgical Approaches for Lower Eyelid Blepharoplasty

Age-related changes in the lower eyelid are noticed by patients as bags or circles under the eye, a tired look, and a flattened face. Lower eyelid blepharoplasty, in which the excess skin and/or orbital fat is excised and repositioned, is mainly performed for aesthetic reasons rather than the correction of functional abnormalities. Favorable outcomes for the combination of these approaches have been reported, but the most suitable surgical technique is still debated. This systematic narrative review deals with the indications, preoperative considerations, operative techniques, and complications of several different surgical approaches to lower eyelid blepharoplasty.

Evaluation of the Portable Next-Generation VECTRA H2 3D Imaging System for Measuring Upper Eyelid Area and Volume

BACKGROUND

Although a portable 3-dimensional (3D) imaging system has been used for periocular measurement analysis, this system has yet to be tested and validated for periocular area and volume measurements.

OBJECTIVES

The aim of this study was to define the upper eyelid and upper eyelid fold region through a modified landmark strategy and validate a portable 3D imaging system for area and volume measurements in this periocular region.

METHODS

Eighty-one healthy adult Caucasians underwent 3D facial imaging with the VECTRA M3 (static) and VECTRA H2 (portable) 3D imaging systems (Canfield Scientific, Inc., Parsippany, NJ). Subsequently, the upper eyelid and upper eyelid fold regions were selected according to a modified landmark localization strategy. Direct measurements of area and volume were performed to assess intrarater, interrater, intramethod, and intermethod reliability, and to compare the agreement between the 2 devices.

RESULTS

The VECTRA M3 and H2 showed high reliability on upper eyelid area measurements. Excellent intra-, inter-, and intramethod reliability agreements were observed in intraclass correlation coefficient; very good agreement in intrarater reliability was observed in the relative error of measurement (REM) and relative technical error of measurement (rTEM); and good inter- and intramethod reliability were observed in the REM and rTEM. For area measurement of the upper eyelid fold, the intrarater, interrater, and intramethod reliability of the M3 was lower than that of the H2. Both systems had poor intrarater, interrater, and intramethod reliability for volume measurements in the upper eyelid and upper eyelid fold region.

CONCLUSIONS

This new portable 3D imaging system achieved excellent or very good reliability values for standardized direct measurements of the upper eyelid and upper eyelid fold region, although volume measurements seem less reliable.

Vectra 3D Simulation in Lower Eyelid Blepharoplasty: How Accurate is it?

BACKGROUND

Estimating the volume of fat to be resected during lower lid blepharoplasty can be challenging. While the excess fat is clearly visible in the upright position, it retracts into the orbital cavity when the patient is in decubitus. Several tools have been developed to predict the volume required for adequate outcomes and to reduce the risk of complications. Among these, 3D photography, in addition to being noninvasive, radiation-free, portable and relatively inexpensive, can be used to make simulations.

OBJECTIVE

To assess the level of agreement between Vectra H1 camera simulations and the outcome of lower eyelid blepharoplasties with volume removal based on these simulations.

METHODS

Preoperatively, a 3D camera and simulation software (Vectra H1, Canfield Imaging Systems) was used to estimate the fat pad volume to be resected from the lower eyelids in a sample of 35 patients (female n = 34) aged 55 years on average. Following the procedure, the patients were photographed at 1, 3 and 6 months and the outcome was compared to the simulation.

RESULTS

The agreement between the simulated volume and the intraoperative volume was high. While the difference between the postoperative volume and the simulated volume decreased over time, at 6 months the actual volume was still 0.30 mL (right eye) and 0.24 mL (left eye) larger than the simulated volume.

CONCLUSIONS

A systematic and significant difference was found between the simulation volume and the postoperative volume. The low level of agreement observed suggests that the accuracy of the tested software is insufficient for reliable simulations.

Treating Excess Lower Eyelid Skin Without Incisions

INTRODUCTION

Periocular rhytids and dermatochalasis are common and striking signs of facial aging. The CO₂ laser technique described herein addresses Hester classification type I, aging at the level of the lower eyelid, focus on the treatment of the dermatochalasis.

MATERIALS AND METHODS

In this retrospective study of patients undergoing treatment at our clinic between 2000 and 2018, 263 were classified as Hester I and CO₂ laser therapy was the treatment to improve the local rhytids.

RESULTS

Improvement in dermatochalasis was found in all patients, resulting in better rejuvenation of the target area while eliminating visible scarring from a suture through the skin.

DISCUSSION

In our experience, CO₂ laser functions as a substitute for transcutaneous lower blepharoplasty, due to the fact that the contracture of the skin renders resection of that skin unnecessarily, thus avoiding the tell-tale scalpel incisions under the lashes.

CONCLUSION

The quality of the results of this retrospective study allows us to offer this laser therapy to treat lower eyelids classified as Hester I.

Treating Tear Trough Deformity: Transconjunctival Blepharoplasty with Fat Pad Repositioning and Fixation in the Intranasal Mucosa-18 Years' Experience

INTRODUCTION

With aging, progressive changes occur in the eyelid region. The novel technique for repositioning of the fat pads described herein addresses Hester classification type II, lower eyelid aging with minimal decrease in the eyelid/cheek juncture.

MATERIALS AND METHODS

In this retrospective study of patients undergoing surgery at our clinic between 2000 and 2018, 92 were classified as Hester II and a transconjunctival surgical procedure was performed with repositioning of the fat pads and intranasal fixation assisted by the Casagrande needle.

RESULTS

Erasure of the nasojugal fold was observed in all patients, offering a greater uniformity in the convexity of the middle third and resulting in better rejuvenation of the target area while eliminating visible scarring from a suture through the skin.

DISCUSSION

The repositioning of fat pads using intranasal fixation offers the necessary anchoring qualities without worrying about unsightly scars or the need to remove stitches early, which can decrease the proper scarring and adhesion of the pads in their new pockets.

CONCLUSION

The quality and longevity of the results of this retrospective study allow us to offer this novel fat pad fixation method in transconjunctival blepharoplasty.
