Remove a nose bump - will the nose be wider from the front?

Thank you for your question. 
Yes, the nose will look slightly wider if the bump is removed.
Oftentimes, we do use osteotomies to broom the bones back so that it does not
look wider.  The fracturing of the bones
sometimes is necessary to close an open roof deformity which may cause an
inverted V.  That is why osteotomies are
often needed for the surgery.  I do my rhinoplasty
procedures under general anesthesia, so that is not a painful process to the
patient.  I hope this helps. 

It is never good idea tell a surgeon what you can handle, you are willing to allow him to perform technically or grab his wrist when he is applying his expertise on you. And if you think this surgeon needs such advice you'd rather seek better hands and opinions for your intervention.

One very well known issue among surgeons who perform revision rhinoplasties, and I carry out many of them, is the so called "open roof deformity". Happens when, as simple as it sounds, the surgeons shaves the dorsum but performs no infractures / lateral osteotomies to close the bony pyramid.





So in short: there is no workaround, dorsal shaving requires necessarily lateral osteotomies, it is a must in the state of the arte more than 100 years ago; not doing so can be within a malpractice scnario and you'd get a flat, undefined and very ugly nose.





On top of that... open roof deformity is associated in 80% of cases with the so called "inverted V deformity", by dissociacion of the bony pyramid from the soft cartilagenous pyramid: the osseous one remains open (no infractures done) but the soft one closes effficiently and beyond the right point, leading to supratip collapse / pinching.





Beware of what you demand, someone could make it real.



ps: fyi, osteotomies are literally painless, this means exempt of any pain in the postoperative, there is no reason to fear them or be reluctant, but for a particular phobia; it is true they lead to massive bruison on eyelids and face, but this is how a rhinoplasty is before you and I were born.



ps bis: osteotomies can be wrongly performed, of course, if the skills are not good, very frequently they are incompetente, fragmental, random, too high, dramatically low, etc, but IMHO is one of the safest and most routinary gestures in rhinoplasty

You are right.  Simply removing the bump will make your nose appear wide and flat.  That is why the bones need to be broken and narrowed at the same time as the hump removal to create the ideal outcome.
