					Augmented Asian Rhinoplasty

    The Art and The Science


            Past, Present and Future


                       Thanee Sakhakorn MD.
    Characteristics of Asian nose

   Wash out dorsum or saddle deformity
   Deficient tip projection
   Wide lobule, thick lobular skin
   Abundant subcutaneous fatty tissue
   Alar flaring
   Retracted columella
Asian saddle nose
      Asian Rhinoplasty requires

   Augmentation of dorsum area
   Augmentation of middle portion of upper
    and lower lateral cartilage areas
   Augmentation of columella-tip area for tip
    projection and increase nasal length
   Refining the lobule/tip area
   Decrease the width of the nostrils
Augmentation Asian Rhinoplasty
    In the old day of Asian rhinoplasty
   Injected liquid
    paraffin or liquid
    silicone

   L-shaped alloplastic
    implant, mainly
    silicone elastomer.



   Rib autograft or
    homograft.
          To the Present time
   Novel design silicone
    implant with tip
    protection using ear,
    septal or lower
    lateral cartilage.

   Autogenous costal
    cartilage graft.

   Autogenous ear
    cartilage graft in
    multiple layers(onlay
    graft).
     To the present time (continue)
   Bioplastic.
    The weird technology:
    hard silicone in solvent.


   Fabricated
    perichondrocartilage
    complex from both
    ears into auto-nasal
    bioprosthesis.
    What is the perichondrocartilage complex?

   Cartilage with intact
    perichondrium.
                                     Finish     Harvest
   In asian rhinoplasty, we
    harvest this complex from
    both external ears.

   The complex will function       Fabricate   Design
    as a living tissue when it is
    implanted in human body.
From raw materials to finished bioprosthesis
       Bioprostheses correct the problems of silicone
             prosthesis in Asian rhinoplasty

   Infection




   Protrusion




   Perforation
Bioprostheses correct the dorsum injecton of
              liquid silicone

          The future is coming
   Regenerative medicine :
     In the future, tissue damages will be replace with
    tissue substitutes.

   Tissue engineering:
     Bioengineer and biomedical engineer make tissue
    substitutes as “body parts” and ready to use. No
    more donor site morbidity and deformity at all.
In cartilage tissue engineer lab
                      Conclusion

   Silicone elastomer and new inert biomaterials still
    have place in asian rhinoplasty.

   Autogenous cartilage fabrication in the form of nasal
    prosthesis will replace and use more and more.

   Cartilage tissue engineering in the form of nasal
    prostheses will be used in the future.
