Is it normal to have swelling in the cheeks and bruising 5 weeks post lower transconjunctival bleph? (photo)

This is especially true after a fat repositioning.  It is also very common if a patient has had more bleeding than normal during a surgery.  I would recommend some warm towels to help speed up the healing.       

The bruising does bring its own swelling.   Overall you look to have a very nice early result.  I don't think you should be concerned about this.  Some surgeons might offer laser of fotofacial to help speed up the resolution of the last bit of bruising.  However, even without this treatment this bruise will clear.  While my crystal ball does not tell me when this will clear, it is likely to be in the next couple of weeks.  As it goes, the swelling will also resolve.

Swelling after lower eyelids

In patients undergoing a simple transconjunctival blepharoplasty, one
should expect only minimal if any swelling after 5 weeks. Ask your doctor if
you has a more advanced procedure, like fat transposition. In this case, you
still could have some residual postoperative swelling. Your doctor should be
willing to see you at any time to answer your questions and concerns

Overall your result looks fine and as expected. Swelling & Bruising can sometimes last longer than anticipated. Bruising has a tendency to "sit " where the soft eyelid skin changes to the firmer cheek skin. Think of it like the bruising is sitting on a "shelf". In any case it is always the Best to call your Surgeons office with any concerns and questions.

The degree of bruising an individual experiences after surgery will be different.  Your bruising has lasted longer then usually expected but I see on evidence of any other problems.  If it is a concern to you follow up with your plastic surgeon.  

It s possible but very rare to see this. Best to seek in person visit with your surgeon to discuss in detail... 

Generally speaking facial swelling after this type of procedure often mostly resolves very quickly in just a few weeks.  Small amounts of swelling can persist a good bit longer.  Occasionally however the swelling can be very prolonged - several months.  Discoloration and fullness can be quite prolonged in these cases.  It will eventually go away.Good luck.
