You will need a complex septorhinoplasty which will make your nose straighter , a little smaller and improve ( not perfectly straight )you breathing dramatically
I have identified your chief concerns as the following: your nose is crooked, has a dorsal bump, is larger than you would like, and you have some functional (breathing) issues that make you snore. Rhinoplasty surgery can address all of these issues. Please do your research well, and find a board certified plastic surgeon with years of experience with rhinoplasty surgery. Read his or her reviews, study his or her background, education, hospital affiliations, and then make an appointment for a consultation. I wish you all the best.
Thank you for your questions and pictures. There are many different ways to perform a rhinoplasty, it is important to communicate with your surgeon prior to your procedure with your particular goals and expectations. The procedure can then be customized to your needs. Best of luck
