Safety and efficacy of the transoral approach for cheek volumization with hyaluronic acid: A pilot study.

Background: With aging, there is a decrease in the volume of facial fat compartments, which can be restored using injectable biodegradable fillers.

Aims: The objective of this study was to assess the efficacy and safety of an ultrasound-guided transoral injection versus the traditional percutaneous approach for cheek volumization with hyaluronic acid.

Patients/methods: This is a pilot, single-center, comparative, prospective study conducted in Spain in which the hemifaces were randomized to receive an injection with each technique, and the duration of follow-up was 1 year.
