Fitzpatrick Skin Type Column 1 Column 2 Column 3 Type 6 Black hair, dark brown eyes. May never burn. Very high risk for trauma, heat & chemical caused pigmentation & lower risk for solar pigmented skin conditions. Very high risk for scarring (keloid) & moderate risk for visible vascular damage. Type 5 Dark and black […]

Chemical peels are classified according their depth of penetration into superficial, medium, and deep depth peels. Superficial peels penetrate into the epidermis and papillary dermis. Extension of chemical peeling agents into the lower reticular dermis produces scarring and is not indicated. Superficial Epidermis and papillary dermis Trichloroacetic acid (TCA) (<30%)m Jessner’s solution, Glycolic acid (10-30%)
Temporomandibular Joint Anatomy: Structure, Function, and Clinical Relevance The temporomandibular joint (TMJ) is one of the most complex synovial joints in the human body, allowing both rotational and translational movement. A thorough understanding of TMJ anatomy is essential for diagnosing and managing temporomandibular disorders (TMD), performing joint surgery safely, and interpreting advanced imaging studies. This

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

Isolated cleft palate is associated with an underlying syndrome more frequently (as much as 50%) than cleft lip and palate. Stickler syndrome has been identified as the most common diagnosis causing both cleft palate and Robin sequence. Patients with Stickler syndrome demonstrate a collagen metabolism disorder. Relevant clinical findings include early myopia and an increased
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

Anterior > posterior When >10mm expansion required Requires osteotomies where potential resistance to lateral expansion will be encountered Palatal suture, lateral buttresses, and pterygomaxillary junction During surgically assisted rapid palatal expansion (SARPE), there is greater widening within the anterior maxilla than there is posteriorly. By contrast, a segmental osteotomy will produce more expansion posteriorly than

Phases of Bone Healing Inflammatory phase Soft callus formation Hard callus formation Bony maturation Distraction Osteogenesis Phase 1: Osteotomy Phase 2: Latency – unique to DO; length varies based on age, location of osteotomy, healing potential of osteotomy site Phase 3: Distraction/Activation Phase 4: Consolidation Distraction osteogenesis comprises of three sequential phases; latency, distraction and consolidation
3 phases: inflammatory, proliferative, remodeling Inflammatory phase: 3-5 days the clot serves as a reservoir of the cytokines and growth factors that are released as activated platelets degranulate. The bolus of secreted proteins, including interleukins, transforming growth factor β (TGF-β), platelet-derived growth factor (PDGF), and vascular endothelial growth factor (VEGF) Once hemostasis is secured
Sinus Drainage Frontal Sinus A pair of air filled cavities in the frontal bone,located superolateral to the nasal ridge Connects with the middle nasal meatus via the frontonasal duct, which drains into the semilunar hiatus (a semicircular opening on the lateral aspect of the middle nasal meatus) Ethmoidal Sinus A collection of air-filled cavities located between the
