PolyBone
NuroSpine
Cranio-Facial Bone defect


* Trauma
* Surgically induced
* Cranio-facial bone tumor
Awesome to patients & surgeons due to
cosmetic problems
Esp) pterional approach (bone defect &
delayed temporal m. atrophy)
PMMA(acryl cement, Resin)
* Most commonly used in Cranio-Facial defect area.
* Advantages
1. Low Price
2. High Mechanical Strength
* Disadvantages
1. May Marked Inflammation Response
2. Fibrous Encapsulation of Implant
-> Possibility of Infection & loosening of implant
PMMA(acryl cement, Resin)
* Disadvantages
3. High temperature (1100 C) generated
-> Tissue damage
4. Shaping of Contour of implant after
hardening is difficult
5. Never convert to Bone
6. No Bone bonding effect
-> Need fixation device (wire, craniofix etc.)
Calcium Phosphate Cement

Advantages:
-

Biocompatible material
Have bone conduction activity
Easily handling
Good osteointegration
Converted to Bone
Disadvantages:
- Low tensile strength than PMMA
- Higher cost
PolyBone
*
Brushite Calcium phosphate Cement(CPC)
-> Convert to bone is fast than other CPC
*
Included Poly-phosphates (Poly-P) : patent
-> Poly-P have bone induction activity
-> So, PolyBone have both bone induction
& conduction activity
PolyBone
*
BoneSource hardening time: 10-20 mins
PolyBone hardening time : within 5 mins
*
Good Bone bonding effect
-> No need of fixation device
such as wire or craniofix etc
.
PolyBone
* Easily making contour during
application & after hardening
- such as knife, or sharp instrument
*
Augumentation during the procedure
is possible (esp. temporal area)
Tips

If dura was slack down below the inner cortex of
bone margin at the bone defect area, put the gelform
on the dura at the bone defect area.
-> not to compress the brain by PolyBone
Tips

If you anticipated of delayed temporal muscle
atrophy, Augmentation of temporal bone area with
CPC is possible.
Tips


It is recommended to use each 5 g package
separated.
Well adhesion of new CPC to already hardening CPC.
Application of PolyBone on
Craniofacial part

Reconstruction of cranial defects
-> If larger defect than 10cm2, use of wire
mesh is recommended.

Closure of frontal sinus opening

Fronto-temporal contouring (Aneurysm Op.)
Clinical Application
on craniofacial area
of
PolyBone
Clinical Application

Fronto-orbito-zygomatic approach

Onlay grafting for augmentation & smoothing
contours of skeletal irregularities

MVD Op.
Clinical Application

Augumentaion of nasoglabellar, supraorbital
rim, mandible

Lateral skull base reconstruction

Translabyrinthine approaches & other skull
base approach
Clinical Application

All of these are non-stress-bearing
areas in craniofacial skeleton
Contraindications of PolyBone







Infected field
Areas surrounding nonviable bone
Abnormal calcium metabolism
Metabolic bone diseases
Recent untreated infection
Poor wound healing
Immunologic abnormalities
Bone Setting CT
X-Ray & 3-D CT
Closure of Oro-Antral Fistula
Closure of Frontal Sinus Opening
Closure of Frontal Sinus Opening
Augmentation of temporal area to
compensate delayed temporal M. atrophy
MVD Op
Obliteration of Sella Floor after
Trans-Sphenoidal Approach
