Bone Structure01:55

Bone Structure

40.4K
Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

Bone Remodeling01:40

Bone Remodeling

34.4K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Area of Science:

  • Plastic Surgery
  • Otolaryngology
  • Regenerative Medicine

Background:

  • Conchal cartilage is a preferred graft in rhinoplasty for aesthetic results.
  • Donor site deformities of the auricle can occur post-harvesting.

Purpose of the Study:

  • Introduce a novel conchal cartilage harvesting technique.
  • Minimize postoperative auricle deformities.
  • Ensure sufficient graft material acquisition.

Main Methods:

  • Preservation of concha cymba and cavum support structures.
  • Harvesting hidden cartilage within the craniofacial region.
  • Retrospective review of 60 patients' medical records.
  • Assessment of aesthetic outcomes using a four-point Likert scale on auricular subunits.
  • Analysis of functional outcomes and complications.

Main Results:

  • High average aesthetic score (3.83/4) indicating minimal deformation.
  • High average functional score (3.94/4) indicating minimal damage.
  • Low complication rate (9.4%) including hematoma, delayed wound healing, and hypopigmented scars.

Conclusions:

  • The novel technique effectively minimizes auricle deformity.
  • Sufficient cartilage graft material can be obtained using this method.
  • The technique offers favorable aesthetic and functional results for rhinoplasty.
