Its always difficult to predict with 100% certainty how much your breathing will change once you narrow any part of your nose. In fact, its often difficult to predict how much your breathing will improve with a septoplasty! But typically those trained in both cosmetic nasal surgery and ENT - Head and Neck surgery have considerable experience dealing with both issues. Here in Ottawa, Canada its something we see commonly. Most times the surgery is highly successfully, both cosmetically and breathing wise. When you breath, airflow is actually along the floor of your nose so theoretically reducing the size of your "wide bridge" shouldn't affect this as this is the upper part of your nose. Unfortunately its a bit more complicated than this. Often times when you narrow the upper part of the nose you also need to tighten the "valve" of your nose. What this does is, prevents the part of your nose above your nostril from collapsing when you breath in. I know, this is alot of info, but hopefully it helps. So, getting to the point this is very possible in the right hands. However, you really have to understand the potential limitations and potential risks of this. You may have a nicer nose, however you may not have an improvement in breathing. Its impossible to predict the outcome with certainty but as mentioned, if you contact the right person, then can at least give you an honest opinion and assessment. Dr Bonaparte
