Don't you worry, your case is not atypical at all, asian rhinoplasty cases are well known and mastered by (few) surgeons who devote to complex structure rhinoplasty cases in certain challenging ethnicities. Essential an asian nose is a nose with underdeveloped skeleton, small bones, cartilages, always a relative or absolut skin deficit, and those skeletal elements the patient was born with are in any case weak and of scarce support, hence your flattened tip, which is not droopy at all but lacking support, maing the tip be shaped like a plateau, lacking projection and upturned or sunken into the nasal pyramid, all these features seen in every and each asian nose. Your nasal bones are not truly asian, only partially, given they are not as underdeveloped as the tip thus forming a doble angle profile; I believe the osseous bridge is optimal in shape and height, I'd not touch it but use it as reference landmark to set the proper poing of nasal tip reconstruction. Find help from a good structure rhinoplasty surgeon with at least some experience in asian cases (afroamerican noses are equivalent).
