Presentation Transcript

  1. PRESENTED BY:ABHILASHA VERMAM.Sc. Prev. PRESENTATION ON FETAL SKULL

  2. FETAL SKULL SHAPE - OVAL

  3. AREAS OF FETAL SKULL

  4. BONES OF FETAL SKULL • FRONT SIDE • BACK SIDE

  5. SUTURE OF FETAL SKULL “Space between skull bones” • Frontal suture • Saggital suture • Coronal suture • Lambdoid suture

  6. FONTANELLS “ Wide gap between suture line where 2 or more suture are meet”

  7. LANDMARKS OF FETAL SKULL • Occiput • Lambda • Vertex • Parietal eminance • Bregma • Siniciput • Glabella • Nasion • Mentum

  8. TRANSVERSE DIAMETERS 1) Biparietal Dm [9.5 cm]: • Distance between parietal eminances. 2) Bitemporal Dm [ 8.5 cm] • Distance between lateral side of temporal bone or coronal suture.

  9. ANTERIOR- POSTERIOR DIAMETER • SUB-OCCIPUTO BREGMATIC DIAMETER [9.5 CM] • From below occipital protuberance to center of anterior fontanelle. 2. SUB-OCCIPUTO FRONTAL DIAMETER [10 CM] • From below occipital protuberance to center of frontal suture. 3. OCCIPUTO FRONTAL DIAMETER [ 11.5 CM] • From occipital protuberance to glabella. 4. MENTO-VERTICLE DIAMETER [ 14 CM] • From chin to vertical point. 5. SUBMENTO VERTICAL DIAMETER [ 11.5 CM] • From junction of mouth and neck to highest point of vertex. • SUBMENTO BREGMATIC [ 9.5 CM] • From junction of neck and lower jaw to bregma.

  10. PRESENTING DIAMETER OF FETAL HEAD

  11. MOULDING “ It is reduction in the diameter of fetal skull which encourage progress of delivery to rigid maternal pelvis without harming fetal brain.” • Skull bones are over ride each other and reduce head circumference.
