Can a You a Have Combined Rhinoplasty/septoplasty/tonsillectomy?

An otolaryngologist (ear , nose, and throat doctor) is the first place to look.  While some otolaryngologists do quite a bit of rhinoplasty, please realize that this is a very challenging aesthetic surgery so you need to make sure that you are choosing the best surgeon for your procedure not just to save money.

Rhinoplasty and tonsillectomy can be combined for healthy patients. Factors such as moderate to severe sleep apnea, advanced age or other medical conditions can raise the risk of airway obstruction following surgery. In certain cases, you might be asked to stay in the hospital for the first night following surgery. However, it is not unusal to combine these two procedures.

Yes, it is possible to have all three surgeries
(rhinoplasty, septoplasty, and tonsillectomy) performed at once. However, it is
probably most advisable to separate the surgeries in two sittings- once for the
rhinoplasty + septoplasty, and once for the tonsillectomy. Although you may be
concerned about taking time off work, it is more important that you have a
safe, comfortable recovery to ensure that you heal properly. 

I definitely don't think it is a good idea to operate on both airways (nasal and oral) at the same time.  I'd rather be safe and stage the procedures.  Good luck. 

I would advise you not to go that route. You are potentially compromising both airways. Any post tonsillectomy issues would be hsrder to treat. Also the pos surgical pain issues would be worse.
