If you require the whole thigh to be treated, then serial surgeries are preferred for the reasons discussed above. These sessions will need to be spaced at least one month apart.
You could, for example, get your outer thighs and hips treated during one session. You could come back a month or more later and have the anterior thighs, inner thighs, and knees treated together.
Performing the treatment in this staggered fashion makes it far less likely that you will suffer from any bothersome swelling of the lower extremities. With serial surgeries, you’ll typically be able to return to work within a day or two of surgery.
