3. What is PRP? Platelets rich plasma. An autologous material.
Easily prepared.
Easily administered
Beneficial in wound healing and rejuvenation

4. The growth factors and other cytokines present in PRP
Platelets derived growth factor.
Vascular endothelial growth factor.
Insulin like growth factor 1 and 2
Fibroblast growth factor.
Transforming growth factor beta.
Epidermal growth factor.
Interleukin 8.
Keratinocyte growth factor.
Connective tissue growth factor.

5. Phases of wound healing
HAEMOSTATIC PHASE
PROLIFERATIVE PHASE
INFLAMATORY PHASE
MATURATION PHASE

6. 1) HEMOSTATIC PHASE Begin immediately after tissue injury.
Platelets migrate and bring to the wound site.
Fibrinogen Fibrin
Thrombin
Platelet/ fibrin structure is formed, growth factors are released from the platelet alpha-granule.
Wound healing starts

7. PRP ADVANTAGES in hemostatic phase
PRP increase plasma with fibrinogen and coagulation factors
PRP increases platelets x 4 times
Platelets with fibrin and without red cells form good clots
Platelets release in about 1 minute GF and continue for about 1 week

8. 2) PROLIFERATIVE PHASE Lasts 4-24 days.
Granulation tissue fills in the wound
Fibroblasts lay network of collagen in wound bed which gives strength to the tissue.
Wound begins to contract and edges pull together.
Epithelial cells from wound margins migrate inwards to cover the wound.

9. 2) PRP ADVANTAGES in proliferative phase
Release GF, chemotactic & mitotic substances
Increase precursor cells

10. 3) INFLAMATORY PHASE
In this phase damaged and dead cells are cleared out, along with bacteria by process of phagocytosis by WBCs
Platelet derived growth factor released into the wound results in migration and division of cells during proliferative phase

11. 3 ) PRP ADVANTAGES in inflammatory phase
Increases number of leucocytes and platelet inflammatory factors
Stimulation of macrophages

12. 4) MATURATION PHASE Lasts 21 days-2 years
Begins when wound has filled in and resurfaced.
Collagen fibers recognize, remodel, mature to give wound tensile strength forming scar tissue.
Scar tissue is only 80% as strong as original tissue.
The key cells in the healing process are macrophages & fibroblasts.
Macrophages engulf and destroy bacteria and clean the wound site of debris.
Fibroblasts synthesize collagen which is the principal component of the connective tissue.

13. 4 )PRP ADVANTAGE maturation phase
1) Stimulates white blood cells and endothelial cells to produce other secondary growth factors.
2) Builds a 3rd matrix signal for differentiation.
Results in faster and better healing.

14. PRP and infections platelet growth factors
concentrated leukocytes, neutrophils, monocytes, and lymphocytes.
Neutrophils and monocytes are rich in granules containing myeloperoxidase, which catalyzes the oxidation of chloride to generate hypochlorous acid and other reactive oxygen derivatives that act as potent bactericidal oxidants toxic to microorganisms and fungi.
Platelets participate in antibody-dependent cell cytotoxicity functions to kill protozoal pathogens
Platelet releases an array of potent antimicrobial peptides

15. Collagen matrix formulation
Platelets release GF
Fibrin
Angiogenesis stimulated
New blood vassels
Scaffold for collagen process
Fibroblasts migrate
Collagen matrix formulation

16. STUDY INTRODUCTION
Rhinoplasty is always associated with bruising nasal swelling nasal block and periorbital edema in the short postoperative period affecting quality of life of the patient badly.
Platelets rich plasma (PRP) is claimed to fasten healing process reducing postoperative edema and bleeding!

17. METHODOLOGY How you did your study Prospective study
2 groups: Control Rhinoplasty without PRP. Study group Rhinoplasty with PRP
Follow up for 3 months for primary outcomes looking at edema, bruises, nasal patency, nose bleeds.

33. CONCLUSION 1. BLEEDING PATTERN 8hr – 48 hr
Patient undergoing Rhinoplasty with PRP are:
LESS LIKELY to experience moderate to severe bleeding in the next 8hr post surgery compared with those without PRP
MORE LIKELY to have no bleeding after 48hr post surgery

34. CONCLUSION 2. PERIORBITAL OEDEMA 48hr – 5 days
Patient undergoing Rhinoplasty with PRP are:
LESS LIKELY to experience severe per orbital oedema within the first 48hr post surgery post surgery compared with those without PRP
MORE LIKELY to have no per orbital oedema after 5 days post surgery

35. CONCLUSION 3. NASAL OEDEMA ( 5 days – 10 days post surgery )
Patient undergoing Rhinoplasty with PRP are:
EQUALY LIKELY to experience mild to moderate NASAL OEDEMA within the first 5 days post surgery compared with those without PRP
MORE LIKELY to experience faster reduction in NASAL OEDEMA over the 10 days post surgery compare with CONTROL GROUP ( rhinoplasty without PRP ).
According to the findings the patient undergoing RHINOPLASTY without PRP do not have any reduction of edema at 10th days assessment compare with the 5th day assessment

36. CONCLUSION 4. BRUISES ( 8 hr./48 hr. / 5 days / 10 days )
Patient undergoing Rhinoplasty with PRP are:
PLEASE COMMENT ON THE FINDNGS ? QUESTIONABLE….BRUISES have a better pattern for non PRP !!!!!

37. CONCLUSION 5 . NASAL PATENCY SUBJECTIVE VARIABLE
IRRELEVANT OVER BOTH STUDY GROUPS
SUBJECTIVE VARIABLE

38. CONCLUSION 6. NASAL PACKING
For the last 2 patient ( Rhino with PRP ) I considered leaving in the nasal packs for 48hr. to assess the edema pattern. ( usually I remove them within the first 8hr post op )
OBSERVATION : edema subsided considerable at 5 days assessment, similar with cases with PRP and packs removed within first 8hr from surgery
