Cranial Bones: Lateral View

Cranial 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...

Nose and Nasal Cavity

Nose 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...

Summary

Cephalometric analysis reveals distinct craniofacial differences in mouth-breathers compared to nose-breathers, including mandibular retrusion and vertical dimension changes. Early diagnosis and intervention are crucial for children

Area of Science:

Dentistry
Orthodontics
Pediatrics

Background:

Mouth breathing can significantly impact craniofacial development.
Understanding these impacts is crucial for early diagnosis and intervention.

Purpose of the Study:

To conduct a cephalometric analysis of craniofacial parameters in mouth-breathers versus controls.
To investigate the relationship between nasal respiration and vertical facial dimensions.

Main Methods:

Cephalometric analysis of headfilms from 53 patients (aged 9-30).
Comparison of craniofacial parameters between mouth-breathers and nose-breathers.

Main Results:

Mouth-breathers exhibited mandibular retrusion (SNB) and posterior rotation.
Increased anterior face height and decreased posterior face height (hyperdivergence) were observed in mouth-breathers.
These changes were associated with retrognathism and open bite.

Conclusions:

Significant cephalometric differences exist between mouth-breathers and nose-breathers.
Multidisciplinary collaboration (pediatric dentists, orthodontists, ENT specialists) is vital for early diagnosis and treatment of childhood mouth-breathing.
