Article: Craniofacial Microsomia Kaban Classification System Type 1: hypoplastic mandibular condyle-ramus complex all skeletal components (glenoid fossa, condyle, ascending ramus) are present with a mild degree of hypoplasia. Normal function is present Type IIa: abnormal shaped ramus with more pronounced hypoplasia of the condyle and TMJ all of the skeletal components demonstrate a moderate degree

Goals of Reconstruction Providing adequate bony matrix for the developing teeth Closure of any residual oronasal fistulas Create alveolar ridge continuity Improve bony support for the nasal base on the cleft side Bilateral cleft palate – stabilize mobile premaxillary segment Incidence of Cleft Lip & Palate Cleft palate: F > M (3:2) Cleft lip: male on

Pathophysiology of MRONJ Proposed hypotheses that attempt to explain the unique localization of MRONJ exclusively to the jaws include Altered bone remodeling or oversuppression of bone resorption Angiogenesis inhibition Constant microtrauma Suppression of innate or acquired immunity Vitamin D deficiency Soft tissue BP toxicity Inflammation or infection Bisphosphonates (BP), and other antiresorptives such as denosumab,

Article Iliac Crest Grafting for Mandibular Reconstruction Marginal VS Segmental Resection Marginal Resection: involves the alveolar portion of the bone with an intact inferior or posterior mandibular border, maintaining continuity. Goal is to restore the morphology of the alveolar process to facilitate placement of dental implants or provide an anatomic foundation for a dental prosthesis. Segmental

Rigid vs Functionally Stable Fixation Rigid fixation: internal fixation that is stable enough to prevent micromotion between bony fragments under normal function Functionally Stable Fixation: internal fixation that is not “rigid” but satisfies the goals of maintaining fragment alignment to permit healing during active use of the bone Rigid Fixation Functionally Stable Fixation (Nonrigid) Reconstruction

Procedure for Preparing Platelet Rich Plasma Draw the appropriate amount of anticoagulant Transfer the anticoagulant into the plasma chamber (white part) 1mL for 20mL and 2 mL for 60mL Draw blood from the patient (20 mL or 60 mL) After drawing the blood, invert the syringe several times to ensure adequate mixing of the blood
