Abdominoplasty or tummy tucks are a very popular operation. One of the risks associated with this procedure is development of a collection of fluid called a seroma. What a group of Plastic Surgeons did was to do a series of ultrasounds at 4,11,18,25 and 32 days.
The lowest incidence of seroma occurred on post op day 4. The highest rate was on day 11! The area with the greatest collection was the left iliac fossa. If a surgeon suspects a seroma then maybe an ultrasound would be beneficial and it may need to be aspirated.
