CONCLUSIONS: The buccal fat pad appears to be more useful as a source of fat tissues in intracordal fat injection than the abdominal fat tissues used previously. However, further studies are required to confirm this point.
OBJECTIVES: Fat tissues used in vocal fold augmentation surgery have primarily been harvested from the subcutaneous region of the lower abdomen. It is often difficult to obtain sufficient fat tissue for injection due to the physical features of the individual patient. We have thus adopted a method using fat tissue from the buccal fat pad, which is already used in other plastic surgeries.
METHODS: This was a retrospective study. We evaluated and compared the histological characteristics of fat cells and the condition of vocal folds after injection of fat tissue extracted from the subcutaneous region of the lower abdomen and from the buccal fat pad.
RESULTS: Buccal fat cells were relatively smaller than abdominal fat cells and were not influenced by body mass index (BMI), showing less individual differences according to the physical features of the patient. Numbers of vascular endothelial cells tended to be higher in buccal fat tissues. The percentage of cases showing continuous effects for more than 6 months was slightly higher in cases using buccal fat.
