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...

Anatomy of Respiratory System I: Upper Respiratory Tract

Anatomy of Respiratory System I: Upper Respiratory Tract

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.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract.

Sutures of the Skull

Sutures of the Skull

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: Superior and Posterior View

Cranial 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,...

Suctioning the Nasopharyngeal Airway

Suctioning 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.

Summary

This study found that sphenoid sinus width is normal in patients with choanal atresia. This indicates typical sphenoid sinus growth despite the condition.

Area of Science:

Otolaryngology
Pediatric Radiology
Craniomaxillofacial Surgery

Background:

Choanal atresia is a congenital condition affecting nasal airflow.
Understanding craniofacial development in choanal atresia is crucial for surgical planning.
Sphenoid sinus development may be influenced by nasal obstruction.

Purpose of the Study:

To investigate the growth and dimensions of sphenoid sinuses in patients with choanal atresia.
To compare sphenoid sinus width in choanal atresia patients versus age-matched controls.

Main Methods:

Retrospective, case-control, single-blinded study design.
CT scans from 15 non-syndromic choanal atresia patients (0-26 years) and 20 controls.
Linear measurements included fronto-zygomatic, zygomatic, maxillary, and sphenoid sinus widths.

Main Results:

No statistically significant difference in sphenoid sinus width between choanal atresia and control groups.
Zygomatic width was significantly smaller in bilateral choanal atresia patients (p=0.03).

Conclusions:

Sphenoid sinus width demonstrates normal growth in both unilateral and bilateral choanal atresia.
Findings suggest choanal atresia does not impede sphenoid sinus development.
