Non-Caucasian Nose Difficult Strengthening weak cartilaginous
structures Preservation major support
mechanisms Careful S-STE manipulation
![Page 47: Rhinoplasty by Dr. Amit Suryawanshi .Oral & Maxillofacial Surgeon, Pune , India](https://reader034.vdocument.in/reader034/viewer/2022052316/5597a6051a28ab2b618b4676/html5/thumbnails/47.jpg)
Non-Caucasian Nose Characteristics Flat, broad, short Infantile dorsum, lacking projection Tip rounded poorly defined Acute nasolabial angle Thick, flaring, wide based alae,
overhanging columella Alar skin thick, fatty, inelastic,
sebaceous glands
![Page 48: Rhinoplasty by Dr. Amit Suryawanshi .Oral & Maxillofacial Surgeon, Pune , India](https://reader034.vdocument.in/reader034/viewer/2022052316/5597a6051a28ab2b618b4676/html5/thumbnails/48.jpg)
Non-Caucasian Nose Characteristics Nostrils round, horizontally ovoid Poorly defined nasofrontal angle Anterior septal angle obtuse,
cephalic Pyriform aperature wide decreased
bone to cartilage ratio Nasal bones, domes more obtuse
angle
![Page 49: Rhinoplasty by Dr. Amit Suryawanshi .Oral & Maxillofacial Surgeon, Pune , India](https://reader034.vdocument.in/reader034/viewer/2022052316/5597a6051a28ab2b618b4676/html5/thumbnails/49.jpg)
Non-Caucasian Nose

Non-Caucasian Nose Limiting Factors
Thick, inelastic S-STE Thick, short columella may preclude
closure Weak thin lateral crura, little support Thin, small septum Preserve ethnicity
![Page 52: Rhinoplasty by Dr. Amit Suryawanshi .Oral & Maxillofacial Surgeon, Pune , India](https://reader034.vdocument.in/reader034/viewer/2022052316/5597a6051a28ab2b618b4676/html5/thumbnails/52.jpg)
Non-Caucasian Nose Many recommend open approach Strut graft, maybe doubled Most no rotation, no cephalic trim Transect domes, no resection, suture at
more acute angle Dorsal grafting, narrowing Multi-layered tip grafts Excise fibro-fatty tissue Cartilage plumping grafts Alar reduction
![Page 53: Rhinoplasty by Dr. Amit Suryawanshi .Oral & Maxillofacial Surgeon, Pune , India](https://reader034.vdocument.in/reader034/viewer/2022052316/5597a6051a28ab2b618b4676/html5/thumbnails/53.jpg)

Aging and Rhinoplasty Cadaveric studies
Alar cartilage flattened, fragmented Loss of upper lower attachments Thin nasal bones Skin thinner less elastic
Skin heals less aggressive, finer scars
![Page 58: Rhinoplasty by Dr. Amit Suryawanshi .Oral & Maxillofacial Surgeon, Pune , India](https://reader034.vdocument.in/reader034/viewer/2022052316/5597a6051a28ab2b618b4676/html5/thumbnails/58.jpg)
Aging and Rhinoplasty Changes in surrounding face Maintain tip support mechanisms
Columellar strut useful Care of septal mucosa Wide undermining of skin possibly Use of external incisions(dorsal) Fine 2-3 mm osteotomes Extended taping
