Noninvasive Correction of the Aging Forehead

Temporal Augmentation Effect of Reduction Malarplasty: Application of our Bracing Technique with Zygomatic Arch Elevation

BACKGROUND

A broad midface is usually accompanied by temporal depression. Traditional reduction malarplasty may visually improve the temporal depression by the inward reduction of zygomatic arch, but also has a high risk of soft tissue sagging. Our bracing technique has been reported to have an anti-sagging effect and may have a temporal augmentation effect as observed during our long-term clinical practice.

METHODS

Data of patients who received reduction malarplasty with our bracing technique from September 2015 to July 2023 were retrospectively collected. The pre-op and post-op CT images of those who met the inclusion criteria were used for three-dimensional reconstruction and measurements of the thickness and volume of the temporal soft tissue as well as the elevation distance of zygomatic arch.

RESULTS

Fifty-eight patients with an average follow-up of 18.4 ± 9.1 months were included. Despite mild thinning of the temporalis muscle after reduction malarplasty, the overall thickness of the temporal soft tissue significantly increased due to the significant thickening of the temporal adipose-fascial layer. There was a 0.5 ml-increase in the temporal volume although without statistical difference. No significant correlation was detected between the elevation distance of zygomatic arch and the temporal thickness or volume change.

CONCLUSIONS

The bracing technique of reduction malarplasty not only plays an anti-sagging role, but also has a temporal augmentation effect through the superior bracing by the elevation and rigid fixation of the zygomatic arch. It adds brilliance to the traditional technique and can be suggested especially when the patients are disturbed by temporal depression.

Using dermal filler to camouflage forehead osteoma: A case report

Objective

To review the technique and outcomes of using dermal filler to camouflage forehead osteoma, providing a minimally invasive alternative to surgical excision.

Background

Forehead osteoma, commonly known as a forehead bump or bone spur, can be a cosmetic concern. Surgical excision, while effective, carries risks of scarring and postoperative complications. An innovative approach using dermal filler offers a potential solution.

Methods

A hyaluronic acid‐based filler is injected into the deep subcutaneous plane over the bony prominence using a cannula. The fanning technique ensures even distribution of the filler. The procedure's safety, patient selection, and communication between the injector and patient are emphasized to achieve optimal results.

Results

The technique provides immediate aesthetic improvement with results that can last up to 12 months, depending on the filler used. While generally safe, potential complications include infections, swelling, asymmetry, and lumpiness. Proper technique, patient selection, and good communication between the injector and patient are critical to achieving optimal outcomes.

Conclusion

Using dermal filler to camouflage forehead osteoma is a minimally invasive alternative to surgical excision, offering immediate and long‐lasting results with minimal downtime and fewer risks. Further studies are needed to refine the technique and optimize outcomes.

Optimizing Botulinum Toxin A Administration for Forehead Wrinkles: Introducing the Lines and Dots (LADs) Technique and a Predictive Dosage Model

This study introduces the Lines and Dots (LADs) technique, a new approach for administering botulinum toxin type A (BoNT-A) in treating forehead wrinkles. (1) Background: BoNT-A application patterns in the forehead often rely solely on the anatomy of the frontalis muscle. The LADs technique proposes a combination of anatomical features with nerve pathways. (2) Methods: The technique employed a grid system aligned with the supraorbital and supratrochlear nerve pathways and used an electronic acupuncture pen for validation. This study analyzed treatment outcomes for efficacy and safety and proposed a predictive model for BoNT-A dosage. (3) Results: LADs was associated with a high satisfaction rate and low side effect incidence. The predictive model followed BoNT-A Units=0.322×Muscle Pattern Code+1.282×Line Type Code+2.905×Severity Pre-Treatment+3.947. (4) Conclusions: The LADs technique offers an alternative approach to treating forehead wrinkles, optimizing efficacy while minimizing the BoNT-A dose required.
