Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

4.2K
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...

Nose and Nasal Cavity01:24

Nose and Nasal Cavity

9.3K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Area of Science:

  • Plastic Surgery
  • Facial Anatomy
  • Reconstructive Surgery

Background:

  • The nose's aesthetic and functional roles are critical.
  • Understanding nasal biomechanics, framework, and aesthetic subunits is essential for reconstruction.
  • Nasal subunits include paired ala, soft tissue facets, sidewalls, and unpaired dorsum, tip, and columella.

Purpose of the Study:

  • To discuss approaches for nasal reconstruction using the aesthetic subunit principle.
  • To provide technical pearls for various nasal defects.
  • To emphasize adapting the subunit principle and combining techniques for optimal outcomes.

Main Methods:

  • Discussion of reconstructive algorithms and techniques.
  • Application of the aesthetic subunit principle in practice.
  • Focus on creating inconspicuous scar lines with "straight lines and sharp corners".

Main Results:

  • The subunit principle aids in planning reconstructions, especially for convex subunits like the nasal tip and alar lobule.
  • Adapting the subunit principle and combining techniques are crucial for defects crossing subunits.
  • The approach focuses on meticulous scar placement within existing nasal contours.

Conclusions:

  • The aesthetic subunit principle is a valuable framework for nasal reconstruction.
  • Understanding subunit anatomy and applying the principle leads to improved functional and aesthetic outcomes.
  • Technical pearls enhance the execution of reconstructions, minimizing visible scarring.
