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...

Epistaxis

Epistaxis

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...

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 summary is machine-generated.

Paranasal sinuses produce nitric oxide (NO), a gas vital for respiratory immunity and oxygenation. Preserving the sinus ostial sphincter function is crucial for maintaining respiratory health and should be prioritized during nasal surgeries.

Area of Science:

Otolaryngology
Respiratory Physiology
Immunology

Background:

Paranasal sinuses are integral to respiratory health, producing and storing nitric oxide (NO).
Nitric oxide (NO) possesses potent antiviral and antibacterial properties, contributing to non-specific respiratory immune defenses.
NO's transport via inspiratory currents enhances pulmonary venous blood oxygenation.

Purpose of the Study:

To emphasize the importance of preserving the ostial sphincter function of paranasal sinuses.
To describe a surgical technique for conserving the maxillary ostium during radical ethmoidectomy.
To discuss the indications for ostial preservation versus antrostomy.

Main Methods:

A step-by-step technical description of maxillary ostium conservation during ethmoidectomy for nasal polyposis.
Surgical technique illustrated with two videos.
Discussion of ostial preservation versus middle meatotomy (antrostomy).

Main Results:

The study presents a method to safeguard the ostial sphincter function during nasal surgery.
It highlights the potential respiratory benefits of preserving this function.
The technique is demonstrated in the context of radical ethmoidectomy with mucosal ablation.

Conclusions:

Conserving the ostial sphincter function is vital for maintaining paranasal sinus physiology and its respiratory role.
Systematic antrostomy should be avoided; ostial preservation should be prioritized when clinically feasible.
This approach supports the non-specific immune defenses of the respiratory tract through nitric oxide (NO) preservation.
