Summary
Septal cartilage thickness varies significantly, being thickest at the base and thinnest centrally and at the anterior septal angle. Understanding these dimensions is crucial for nasal stability during rhinoplasty.
Area of Science:
- Anatomy
- Surgical Science
- Biomechanical Engineering
Background:
- The nasal septum's cartilage is vital for nasal stability but is frequently altered during septorhinoplasty.
- Surgical procedures like dorsal hump reduction and cartilage grafting routinely involve manipulating septal cartilage.
- Inadequate characterization of septal cartilage properties hinders understanding of its structural role.
Purpose of the Study:
- To precisely define the anatomical characteristics of septal cartilage.
- To provide quantitative data on septal cartilage thickness and dimensions.
- To elucidate the implications of these characteristics for nasal structural stability and surgical outcomes in rhinoplasty.
Main Methods:
- Quantitative analysis of septal cartilage dimensions using fresh cadaver specimens.
- Systematic measurement of septal length, height, and thickness at 5-mm intervals.
- Mapping of cartilage thickness across the entire nasal septum.
Main Results:
- Significant variations in septal cartilage thickness were observed across different regions.
- The thickest cartilage was found at the septal base (2.7 mm), followed by the dorsum (2.0 mm).
- The central portion (1.3 mm) and anterior septal angle (1.2 mm) exhibited the least thickness (p < 0.001).
Conclusions:
- Findings clarify nuances of septal structural stability and deformity.
- Highlights factors contributing to central septal perforations and supratip deformities post-rhinoplasty.
- Emphasizes preserving L-strut width and prudent cartilage graft allocation during surgical alterations.

01:27Cranial Bones: Lateral View
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...

01:24Nose and Nasal Cavity
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...
01:30Epistaxis
Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

01:29Suctioning the Nasopharyngeal Airway
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

01:14Cranial Bones: Superior and Posterior View
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,...
