Buccal Fat Suspension: Not Just a Lift-Restoring the Foundational Anatomy of a Youthful Cheek

The senior author has combined buccal fat suspension with facelift surgery to restore youthful cheek volume and contour. This technique consistently produces softening of the nasolabial fold as a secondary benefit. However, no existing anatomic model adequately explains this effect.

This study was designed to identify the anatomic mechanism by which buccal fat suspension softens the nasolabial fold.

Buccal fat suspension was reverse-engineered on fresh cadaveric specimens. Four consistent effects on the middle third of the cheek were identified, which generated four targeted anatomic questions. These questions were addressed through layered and cross-sectional dissections of 20 hemifaces from 10 fresh cadavers (mean age 68.2 years).

The study identified a functional "buccal sling." Traction on the buccal fat and its capsule transmits tension through these structures to the transverse facial septum. This tension repositions the deep medial cheek fat medially, thereby softening the nasolabial fold.

Buccal fat suspension is not merely a lift; it re-establishes the buccal sling and inferior cheek border, while recreating the shape and contour of a youthful, attractive "Nefertiti cheek." Hoxworth suggested that attenuation of the buccal capsule is the initiating factor in jowls. Building on the prior work of Mendelson and Matarasso, the authors propose the "Buccal Cascade" as a bottom-up model of midfacial aging in which progressive attenuation of the buccal capsule ultimately leads to malposition of the deep medial cheek fat and pseudoatrophy.
