Can a surgeon be too aggressive with buccal fat pad removal?

The amount of buccal fat to be removed during surgery varies according different factors. Those factors include the amount of buccal fat encountered and most importantly the cheek look that ultimately the patient would like to achieve. 
In muy practice most of patients like to have a thinner lower face so partial buccal fat removal is performed. Other of my patients, specially New York City models, they want a hollow cheek look, therefore all the buccal fat is removed during surgery. 

Generally, we remove about 1 gram of buccal fat which is about the size of an egg yolk. The fat that easily protrudes through the incision is all that is removed. Some fat needs to be left in place to cushion the area and allow the chewing muscles to glide freely. It is possible to remove too much fat if the surgeon is too aggressive or poorly trained. An experienced Facial Plastic Surgeon would be the safest bet.
