Can you shorten an over projected septum and can you fix a crooked tip?

Thank you for your questions.
Rhinoplasty is frequently performed in combination with Septoplasty (called Septorhinoplasty) to correct a deviated nasal septum (the cartilage in the nose that separates the nostrils) causing a blocked nose and/or to harvest septal cartilage and use it as a graft to improve nasal support or shape.
Septorhinoplasty can alter both nasal and septal length and shape.
This is one of the most delicate and complex cosmetic surgeries, given the intricate structure of the nose and the balance it provides to a face.
It is a common misconception to think that the nose can be sculpted as if it was a piece of marble or that one can choose a “perfect” celebrity nose from a magazine.
There are limitations based on the individual's intricate nasal anatomy and nasal skin quality. For example, a thick nasal skin is great in covering up minor irregularities but since it does not shrink well after surgery, it will not show fine underlying refinements.
I would suggest that you consult with an expert rhinoplasty surgeon and discuss what you do and do not like about your nose.
You should expect a full detailed examination of your nose is required to assess your nasal skin, cartilage, bony structures, and your nasal airway/ breathing. This will allow the surgeon to evaluate your nasal appearance and its relation to your facial features.
The use of manipulated (morphed) digital clinical photography provides a platform for discussion as to your desires and expectations. Such images are not a guarantee of exact results, but a great tool to ensure that you and your surgeon are on the same wavelength.
It is paramount that you have a realistic expectation before proceeding with this surgery.
Best wishes,

Your concerns expressed can usually be corrected with a rhinoplasty, but pictures will be necessary for a better evaluation of your case. I suggest you to book a virtual or in person consultation where you can share additional photos and get a better advice from your doctor.
