Sutures of the Skull01:22

Sutures of the Skull

7.8K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Prosopagnosia01:24

Prosopagnosia

278
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

Genetic Variation01:25

Genetic Variation

403
Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.
Genes exist in different versions called alleles,...

Area of Science:

  • Plastic Surgery
  • Anatomy
  • Surgical Techniques

Background:

  • Genioplasty has evolved from osseous to include alloplastic techniques since the 1950s.
  • Understanding facial anatomy and the zero meridian is crucial for assessing chin deficiencies.

Purpose of the Study:

  • To guide surgeons on the anatomy and techniques for alloplastic and osseous genioplasty.
  • To assist in patient selection and determining the optimal genioplasty approach for desired outcomes.

Main Methods:

  • Review of facial anatomy, including vertical thirds and landmarks.
  • Description of virtual surgical planning, ultrasonic bone saws, and surgical approaches (intraoral/external).
  • Evaluation of patient criteria for alloplastic vs. osseous genioplasty.

Main Results:

  • Detailed surgical techniques for both osseous (intraoral) and alloplastic (external/intraoral) genioplasty.
  • Discussion of patient assessment for advancement, vertical height, asymmetry, and chin reduction.
  • Consideration of postoperative care, including edema and diet.

Conclusions:

  • Virtual planning and improved implant technology enhance genioplasty outcomes.
  • Genioplasty, whether alloplastic or osseous, requires careful anatomic consideration for optimal results.
  • The article summarizes the advantages and disadvantages of both genioplasty types.
