Summary
Cribriform plate (CP) dimensions increase with septal deviation (SD) severity. Deeper contralateral CP depth in SD patients requires careful consideration during surgery to prevent intracranial injury.
Area of Science:
- Otolaryngology
- Neurosurgery
- Radiology
Background:
- Septal deviation (SD) is a common condition affecting nasal airflow and sinonasal health.
- The cribriform plate (CP) is a critical anatomical structure at the skull base, separating the sinonasal cavity from the anterior cranial fossa.
- Understanding the relationship between SD and CP morphology is crucial for surgical planning and preventing complications.
Purpose of the Study:
- To investigate the relationship between cribriform plate (CP) dimensions and the degree of septal deviation (SD).
- To compare CP dimensions on the ipsilateral and contralateral sides relative to the direction of septal deviation.
- To assess the impact of SD severity on CP morphology.
Main Methods:
- Retrospective review of coronal paranasal CT scans from 99 patients.
- Measurement of cribriform plate (CP) depth and width on both sides.
- Comparison of CP dimensions with septal deviation side and deviation angle.
Main Results:
- Cribriform plate (CP) depth at the contralateral side was significantly higher than at the ipsilateral side in patients with septal deviation (SD).
- Both ipsilateral and contralateral CP width, as well as right and left CP width, increased with increasing deviation angle.
- CP width and depth increased simultaneously with increasing septal deviation.
Conclusions:
- Septal deviation is associated with significant alterations in cribriform plate (CP) dimensions.
- The contralateral CP depth is notably increased in the presence of septal deviation.
- Awareness of these anatomical changes, particularly the deeper contralateral CP, is essential for surgeons to minimize the risk of iatrogenic intracranial injury during sinonasal procedures.

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...

01:21Deformations in a Transverse Cross Section
When a material is subjected to uniaxial stress, it elongates or contracts in the direction of the applied force, and also undergoes changes in the perpendicular directions. This behavior is crucial for understanding how materials behave under stress and is governed by mechanical properties such as Poisson's ratio v, which measures the ratio of transverse strain to axial strain.
As the material stretches, it expands or contracts in orthogonal directions to the load. This phenomenon varies...

01:18Deformations in a Symmetric Member in Bending
When analyzing the deformation of a symmetric prismatic member subjected to bending by equal and opposite couples, it becomes clear that as the member bends, the originally straight lines on its wider faces curve into circular arcs, with a constant radius centered at a point known as Point C. This phenomenon helps to understand the stress and strain distribution within the member more clearly.
When the member is segmented into tiny cubic elements, it is observed that the primary stress...

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,...

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...
