Sutures of the Skull01:22

Sutures of the Skull

14.8K
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...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

8.3K
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 View01:14

Cranial Bones: Superior and Posterior View

9.1K
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,...

Nose and Nasal Cavity01:24

Nose and Nasal Cavity

17.2K
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...

Overview of the Skull01:08

Overview of the Skull

9.5K
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

Summary

Achieving a desirable nasal tip contour requires a 3D approach, considering parameters beyond cartilage structure. New surgical aspects enhance functional and aesthetic outcomes for durable nasal tip reconstruction.

Area of Science:

  • Plastic Surgery
  • Rhinoplasty
  • Facial Anatomy

Background:

  • Nasal tip contouring is complex, with traditional excisional and suture techniques often yielding suboptimal aesthetic and functional results.
  • Common issues include alar pinching, caudal displacement, loss of structural continuity, and unnatural shadowing, impacting both appearance and breathing.
  • Evaluating nasal tip aesthetics solely on alar cartilage stability is insufficient; a comprehensive 3D analysis is necessary.

Purpose of the Study:

  • To introduce novel surgical considerations for nasal tip contouring.
  • To improve functional and aesthetic outcomes in rhinoplasty.
  • To present a 3D analytical approach for nasal tip surgery.

Main Methods:

  • Analysis of nasal tip structures using a three-dimensional approach.
  • Consideration of specific parameters like the rotational angle of the alar surface.
  • Evaluation of the longitudinal axis of the lateral crus relative to the cranial septum.

Main Results:

  • Identification of key parameters for nasal tip aesthetics and function.
  • Development of new surgical aspects for nasal tip reconstruction.
  • Improved understanding of factors contributing to unpredictable deformities in traditional techniques.

Conclusions:

  • A 3D perspective is crucial for understanding and reconstructing the nasal tip.
  • Incorporating specific anatomical parameters leads to more predictable and satisfactory surgical results.
  • The presented surgical aspects aim for functionally and aesthetically pleasing, durable nasal tip contours.
