Hello! yes you do have a bulbous tip and your nose is big for your facial profile. You will need a reduction of the nose, tip refinement as well as alar reduction. More details can be discussed when you consult in person or virtual with a plastic surgeon ,depending upon your areas of concern. Also you seem to have thick skin so that will be an additional point of discussion.
Ultrasonic device or the piezotome is a device used for doing bone work in rhinoplasty. So yes it can be combined with tip pasty. The cost will really depend on what all needs to be done and for that you need share some pictures.
At 10 months it is very unlikely that this is swelling. However, to consider a revision rhinoplasty I would advise you to wait for atleast 1 year. Usually the swelling after rhinoplasty is symmetrical. Sometimes asymmetrical swelling also does occur but this doesn’t look like an asymmetrical swelling. It is significant likely that you will need a revision for correction. I would suggest you go to your operating surgeon and discuss the possible options.
