I have in my nose something called "The PDS Plate" does it increase the swelling?

PDS flexible plate is a sheet made up of the same material that is often used as an absorbable suture. PDS is the material and it should dissolve within 6 months. When it is used as a plate, PDS can be used to help repair the septum. It is a tool that is available to us when performing rhinoplasty. Having the the pds plate in your nose should not negatively affect your long term results. In fact, if your doctor used it in your nose, one must believe that it was to benefit you and get you the best possible results. 

Hard to know if this is a factor.The nose
can be swollen for up to a year or more. Swelling will depend upon the
nature of maneuvers employed, presence of grafts or implants, thickness
of skin, open vs closed, revision vs primary, etc. Kenneth Hughes, MD Los Angeles, CA

The PDS Flexible Plate is a absorbable sheet of material made from the same compound (polydioxanone) as a commonly used suture in rhinoplasty. It is typically dissolved in approximately 6 months and should not impede additional surgery.
