In General most of your swelling should resolve by three months, fat stability will also be seen at this time, and sensation can take on average 3-6 months in most areas and 6 - 12 months in the area in front of the ears.  

Your most lasting treatment option would be a facelift.  But other options exist such as thread lifts, RF Skin tightening, Fat Reduction, and certain fillers may be helpful.  Consult with an experienced plastic surgeon to learn about the pros and cons of each.  

It looks like your surgeon did a MACS type facelift using a purse string type suture for resuspending your cheek tissue.  When the face was swollen the underlying irregularities were not obvious.  Massage can help, but I would not be too aggressive as you may break the suture before the tissues stabilize, or you may tear the tissue.  You may eventually need a revision, fillers, or fat grafting in the area, if it doesn't correct over time.  

This is a direct question for your own plastic surgeon as each of us has a different protocol, and that protocol may vary based on what has been done.   A simple phone call to their office should clear things up.

The return of these bands can come from a number of reasons.   If a platysma plasty in this area needs to be corrected, it can be performed under local anesthesia.  However you would want to wait several months to allow the tissue swelling from your first surgery to soften, if the neck was previously dissected.  If it wasn't, then you may be able to go back sooner. 

These two procedures can be combined.  The laser needs to be adjusted for areas that have been undermined and thinner areas.  See Jason Posner's answer below.  He has done a lot of work and research in this area and has proven it to be safe.  

Yes. The best thing you can do is ask your surgeon to hold pressure on your nose for 10 minutes after breaking it in the operating room.  I routinely do this and it has resulted in far faster recovery from surgery with minimal bruising and swelling.  

I have never seen this specific response in a patient taking accutane.  However one of the things accutane does is to shrink oil gland production and thus gland size.  The tip of the nose has a high degree of the glands and it may be that the glands in the skin were really big before you started the medication.  Now with them smaller you see more of the underlying shape.  Some fillers may correct this. 

This is called a hanging tip or a plunging tip.   It requires rotating the tip cartilages upward and reshaping them.  It will probably also require a trim of the lowest part of the septum and long term stabilization with a columella strut.  I would consult with an experienced rhinoplasty surgeon who is familiar with masculine rhinoplasty surgery.    Costs vary and return to work with my patients is usually one week.  Full healing for most activities is one month and one year for last bits of swelling to go down. 

This can have a number of different causes.  The most common is a soft or crooked columella.  A columella strut may be useful, but you will also have to look and make sure the septum is straight and the alar rim is strong enough.  Get a consult with an experienced nose surgeon.  This is a complex problem.
