Should Asian Nose-concerns (Ie:fractures, Broken Nose, Sinusitis) Be Approached & Diagnosed Like Other Ethnicities?

Anatomically there certainly are differences, but a well trained otolaryngologist will be able to account for these.  When it comes to a closed reduction of a fracture, sinus surgery, or septoplasty, you can expect excellent treatment from an otolaryngologist.  

The need for an Asian rhinoplasty specialist comes into play more during rhinoplasty - or reshaping of the nose.  This is because the aesthetics of the Asian nose certainly are different from other ethnicities, and it's important to seek out a surgeon familiar with the subtleties and nuances of your nose - and knows which techniques will achieve the best results during surgery.  

Asian rhinoplasty takes into account the unique features particular to Asian patients in order to give each patient a nose that looks natural. With any ethnic rhinoplasty, the goal is to improve the appearance and/or function of the nose without making it look altered.

Asian Rhinoplasty definitely requires specific knowledge and skill set to perform properly. The anatomic structures in Asian noses need special attention to create predictable and esthetic result. In your particular case, it sill take a few more weeks to determine if the nasal trauma resulted any any esthetic changes. Likewise, it can take at least a month before any internal swelling subsides to determine if there is any need for functional surgery. Seek some one with significant experience treating Asian noses whether for functional or esthetic evaluation.

You need to be evaluated by a plastic surgeon to determine if there is an internal injury which may be affecting your breathing. If there is no external deformity from the injury such as a fracture, you may only need airway work done. You should seek out a competent nasal surgeon in your area, whether that surgeon claims to be an expert on Asian rhinoplasty or not.

For non cosmetic issues the treatment variations are the same. Cosmetic Asian rhinoplasty addresses common problems of the Asian nose. An experienced ENT surgeon or Facial Plastic surgeon can deal with these issues as well as general plastic surgeons
