Nose and Nasal Cavity01:24

Nose and Nasal Cavity

12.8K
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

5.7K
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....

Epistaxis01:30

Epistaxis

626
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 Airway01:29

Suctioning the Nasopharyngeal Airway

3.9K
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.

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

7.5K
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...

Chronic Pharyngitis01:23

Chronic Pharyngitis

12.9K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

    Summary
    This summary is machine-generated.

    Nasal polyps affect 1-4% of people, often linked to other diseases like chronic rhinosinusitis (CRS). While not curable, nasal polyps can be managed with intranasal corticosteroids and, if needed, surgery.

    Area of Science:

    • Otolaryngology
    • Pulmonology
    • Allergy Immunology

    Background:

    • Nasal polyps affect 1-4% of the population, frequently associated with underlying conditions.
    • Chronic rhinosinusitis (CRS) is the most common condition linked to nasal polyps.
    • Other associated conditions include allergic fungal rhinosinusitis, aspirin-exacerbated respiratory disease, Churg-Strauss syndrome, and cystic fibrosis.

    Purpose of the Study:

    • To review the current understanding of nasal polyps, their associations, and management strategies.
    • To evaluate the efficacy of medical and surgical treatments for nasal polyposis in the context of CRS.

    Main Methods:

    • Literature review of existing medical evidence.
    • Analysis of treatment outcomes for intranasal corticosteroids, oral corticosteroids, antibiotics, and functional endoscopic sinus surgery.

    Main Results:

    • Nasal polyps associated with CRS are generally not curable but controllable.
    • Intranasal corticosteroids are supported by evidence for maintenance therapy.
    • Short courses of oral corticosteroids are effective for exacerbations; antibiotic evidence is less robust.
    • Functional endoscopic sinus surgery is an option for medically refractory cases.

    Conclusions:

    • Management of nasal polyps, particularly in CRS, focuses on control rather than cure.
    • A stepwise approach utilizing corticosteroids and potentially surgery is recommended.
    • Further research may clarify the role of antibiotics in nasal polyp management.
