Clavicular Contouring with a Novel Subperiosteal Filler Injection Technique: A Single-Case Study

Area of Science:

• Medical Aesthetics
• Injectable Cosmetics
• Dermal Fillers

Background:

• Injectable cosmetic procedures are increasingly popular.
• Advancements in technology and materials facilitate minimally invasive aesthetic treatments.
• Subperiosteal injection is a novel technique not yet established in medical aesthetics.

Purpose of the Study:

• To confirm the feasibility of subperiosteal injection of dermal filler.
• To validate this novel technique using the clavicle area and ultrasound.
• To explore its potential for improved contouring and addressing filler displacement.

Main Methods:

• A new technique involving linear limited subperiosteal dissection with a cannula.
• Expansion of the periosteum via injection pressure to facilitate subperiosteal filler placement.
• Combination of sharp and cannula techniques for subperiosteal filling.

Main Results:

• Clinical observation and ultrasound validation confirmed successful subperiosteal injection.
• The dermal filler provided very stable support at the subperiosteal level.
• Ideal results were maintained at the 6-month follow-up.

Conclusions:

• The subperiosteal injection technique is practical and easily promoted.
• It achieves long-term stable outcomes surpassing traditional injection methods.
• Applicable to various facial injection sites beyond the clavicle area.
