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.

Gross Anatomy of Bone01:17

Gross Anatomy of Bone

14.4K
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...

Bone Markings01:26

Bone Markings

8.9K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

Compact Bone01:27

Compact Bone

22.5K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

6.8K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Spongy Bone01:09

Spongy Bone

12.9K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

Summary
This summary is machine-generated.

Bony dorsal preservation (BDP) is a new rhinoplasty technique for crooked noses. It enhances dorsal preservation rhinoplasty (DPR) by allowing independent adjustment of the nasal vault, improving stability and outcomes.

Area of Science:

  • Plastic Surgery
  • Facial Plastic Surgery
  • Rhinoplasty Techniques

Background:

  • Rhinoplasty techniques are evolving, with a resurgence in dorsal preservation rhinoplasty (DPR).
  • Existing DPR methods, like the low septal strip (LSS), have limitations.
  • Crooked nose correction presents unique challenges in rhinoplasty.

Purpose of the Study:

  • Introduce and describe a novel technique, bony dorsal preservation (BDP), as an advancement in DPR.
  • Detail the application of BDP for correcting crooked noses.
  • Compare BDP with existing DPR techniques, particularly LSS.

Main Methods:

  • BDP involves temporarily separating upper lateral cartilages from the septum while preserving the septal base.
  • This allows independent adjustment of the osseocartilaginous vault before reattachment.
  • The technique provides direct visualization during septal excision and fixation.

Main Results:

  • BDP maintains DPR principles, avoiding open roof deformities during hump reduction.
  • It offers more septal cartilage for harvesting compared to LSS.
  • Eliminates risks associated with a single point of septal fixation and allows potential transition to component reduction.

Conclusions:

  • BDP is a valuable addition to DPR, particularly for crooked nose correction.
  • The technique offers enhanced stability and surgical control.
  • It addresses drawbacks of previous DPR methods, providing a refined approach to nasal vault adjustment.
