Summary
Cone beam computed tomography (CBCT) reveals that nasal septum deviation is linked to hyperdivergent facial development. Hypodivergent facial types show no septal deviation, indicating a connection between nasal anatomy and vertical facial growth.
Area of Science:
- Dentistry
- Orthodontics
- Radiology
Background:
- Limited research exists on the correlation between cone beam computed tomography (CBCT) findings and nasal passage characteristics in relation to vertical facial development.
- Understanding this relationship is crucial for comprehensive orthodontic diagnosis and treatment planning.
Purpose of the Study:
- To investigate the association between nasal cavity anatomy, as visualized by CBCT, and the vertical facial development patterns in patients.
- To identify specific nasal passage parameters that may differ between individuals with varying vertical facial growth.
Main Methods:
- Sixty cone beam computed tomography (CBCT) scans of Class I malocclusion patients were analyzed.
- Participants were categorized into two groups (n=30 each) based on their vertical facial development (hyperdivergent vs. hypodivergent).
- Nasal septum deviation, nasal cavity width, thickness, and angle were quantitatively assessed.
Main Results:
- A significant relationship was established between vertical facial development and nasal cavity findings.
- Mild to moderate nasal septum deviation was observed in the hyperdivergent group, whereas the hypodivergent group exhibited no septal deviation.
- Statistically significant differences (p<0.05) were noted in nasal cavity width, distance (x-y), and angle in the hyperdivergent group compared to the hypodivergent group.
Conclusions:
- Significant differences in anterior face height, nasal passage angle, and nasal cavity dimensions were found when comparing low-angle (hypodivergent) and high-angle (hyperdivergent) facial types.
- These findings suggest that nasal cavity morphology may serve as an indicator of vertical facial patterns.

01:24Nose and Nasal Cavity
3.0K
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...

01:27Cranial Bones: Lateral View
2.3K
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...

1.8K
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.

01:14Muscles for Facial Expressions
2.3K
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

01:08Overview of the Skull
4.8K
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...

01:03Olfactory Receptors: Location and Structure
9.4K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
