Scalp

  1. 1. Scalp Dr. Deepak K Gupta www.facebook.com/notesdental
  2. 2. Introduction • It is the soft tissue that covers the vault of skull • Extends from sup.orbital margin to superior nuchal line • On each side to superior temporal line • It is hair bearing area of the skull www.facebook.com/notesdental
  3. 3. Layers of Scalp • S-Skin • C-connective tissue (superficial fascia) • A-aponeurosis (galea aponeurotica) • L-loose areolar tissue • P-pericranium www.facebook.com/notesdental
  4. 4. Layers of Scalp www.facebook.com/notesdental
  5. 5. Skin • Thick and hairy • Firmly attached to the epicranial aponeurosis through dense fascia • Abundance sebaceous glands • Sebaceous cyst are common www.facebook.com/notesdental
  6. 6. Connective tissue • Fibrous and dense containing blood vessels and nerves • Binds skin to subjacent aponeurosis • Wounds bleed profusely as blood vessels are prevented from retraction by fibrous tissue. Bleeding is stopped by applying pressure against the bone • Subcutaneous hemorrhage are not extensive since fascia is dense • Inflammation cause little swelling but are much painful www.facebook.com/notesdental
  7. 7. www.facebook.com/notesdental
  8. 8. Aponeurosis • Anteriorly frontal belly and posteriorly occipital belly of occipitofrontalis muscle • Frontal belly originate from skin of forehead • Occipital belly originate from lateral 2/3 of superior nucheal line • It gaps if cut transversely and should be stitched www.facebook.com/notesdental
  9. 9. www.facebook.com/notesdental
  10. 10. Loose areolar tissue • Extends anteriorly into the eyelids because frontalis has no bony attachment • Posteriorly to superior nuchal line • On each side to superior temporal line • Bleeding cause generalized swelling of scalp • Called dangerous layer of scalp-emissary veins open here and carry any infections inside the brain (venous sinus) • Bleeding lead to black eye • Caput succedaneum in new born www.facebook.com/notesdental
  11. 11. Pericranium • Is the periosteum of skull • Loosely attached to surface of bone but is firmly adherent to the sutures • Injury deep to it take the shape of bone (cephalhaematoma) • Scalping injury- should be replaced and stitched because healing is better www.facebook.com/notesdental
  12. 12. www.facebook.com/notesdental
  13. 13. Blood supply • Arteries – Supratrochlear – Supraorbital – Superficial temporal – Posterior auricular artery – Occipital artery • Veins-follows the artery www.facebook.com/notesdental

  15. 15. Nerve supply • In front of auricle – Supratrochlear n. – Supraorbital n. – Zygomaticotemporal n. – Auriculotemporal n. – Temporal branch of facial n. • Behind auricle – Greater auricular n – Lesser occipital n. – Greater occipital n. – Third occipital n. – Post. Auricular branch of facial n. www.facebook.com/notesdental
