The appearance of the nose is a delicate interplay between shadows and highlights. There is a relative relationship between width and height that determines the strength of the highlights (where light reflects) and the depths of the shadows. The contrast between these 2 then determines how "narrow" the nose looks after surgery. Tall noses with a bump tend to have very strong highlights and shadows since the height to wideth ratio is very high. When a bumb is removed, that ratio changes. This is why bone work is typically done to narrow the nose. This narrowing re-establishes the shadow/highlight/shadow appearance as one looks across the nose, providing the perception of a narrow nose. With respect to your question: most reduction rhinoplasties do produce a slight flattening of the area that you describe. While this, to most patients, may seem like a problem, it typically does put the nose into overall better balance. Best of luck!
