Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

3.7K
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...

Cranial Bones: Superior and Posterior View

4.1K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Area of Science:

  • Plastic Surgery
  • Rhinoplasty Techniques
  • Nasal Anatomy

Background:

  • Cephalic trimming in lower lateral cartilage (LLC) surgery risks nasal valve collapse and deformities.
  • The cephalic lateral crural advancement (CLCA) technique aims to improve nasal tip support and rotation without grafts or excision.

Purpose of the Study:

  • To evaluate the efficacy of the CLCA flap technique in rhinoplasty.
  • To assess the impact of CLCA on nasal tip definition, rotation, and nasal valve support.

Main Methods:

  • Retrospective analysis of 32 patients undergoing open rhinoplasty with the CLCA flap.
  • LLC elevation using a CLCA flap, preserving the scroll ligament complex.
  • Advancement of the CLCA flap onto the lower lateral crus.

Main Results:

  • High patient satisfaction (93% perfect satisfaction) with Rhinoplasty Outcome Examination scores of 90-100.
  • Significant improvement in nasal patency (visual analogue scale) from 4.56 to 9.0 (P<0.001) at 1-year follow-up.
  • The CLCA flap protected the scroll area, enhancing tip definition and rotation.

Conclusions:

  • The CLCA flap technique provides superior nasal tip definition and support.
  • It effectively supports internal and external nasal valves without requiring cephalic excision.
  • This technique offers a promising alternative for improving aesthetic and functional outcomes in rhinoplasty.
