Seeking great, experienced doctor & advice on decreasing width & nostrils size, & defining bone to create facial harmony

I don't want to drastically change my features more of just improve them. I have sinus issues, hope to improve both health and appearance. What are your recommendations? My ethnicity consists of African, European and East Asia descent. My understanding is genetic makeup makes my nose structure somewhat different and may require certain skills, experience and expertise. I appreciate the help.
