Week 6: Rhinosinusitis (upper airway disorder) Flashcards
Epidemiology
- symptomatic inflammation of the nasal cavity and the paranasal cavity
- also called sinusitis but rhinosinusitis is a more comprehensive term
Classification of Rhinosinusitis
-based on duration of symptoms and includes acute, subacute, and chronic
>acute (less than 4 weeks)
>subacute (4 to 12 weeks)
>chronic (more than 12 weeks)
Acute Rhinosinusitis
etiology as acute bacterial rhinosinusitis (ABRS) or viral rhinosinusitis
-viral upper respiratory infections that spread to the paranasal sinuses are the cause of most acute rhinosinusitis, which then can lead to bacterial infections
Pathophysiology
- infection and inflammation of the paranasal sinuses, the four paired air-filled spaces that surround the nasal cavity
- maxillary, frontal, sphenoid, and ethmoid sinuses
- inflammation of the nasal passages cause vasodilation, increased blood flow, and vascular permeability, reducing the size of the nasal passages
How does Nasal Congestion Occur?
as a result of swelling of the nasal turbinates, bony structures along the nasal passages that aid in maintaining moisture and trapping airborne particles
-results in obstruction of nasal airflow
Risk Factors
-viral upper respiratory infections that spread to paranasal sinuses
-deviated nasal septum
-trauma to the nose
-tumors
>the last 3 can interfere with nasal drainage and contribute to the development
Bacterial Species found in the cultures of Rhinosinusitis
-Streptococcus pneumoniae
-Haemophilus influenzae
-Moraxella catarrhalis
>lack of nasal airflow and increased drainage of nasal secretions provide the medium for bacterial growth
>Staphylococcus aureus and anaerobics can also cause rhinosinusitis
Acute Rhinosinusitis is diagnosed with 3 symptoms
- Purulent nasal discharge
- nasal obstruction
- facial pain, pressure, and fullness
Nasal Secretions in Rhinosinusitis
- yellow-green nasal discharge
- colored or cloudy in nature
Clinical Manifestations
- purulent nasal discharge, nasal obstruction, facial pain, pressure, and fullness
- other: fatigue, fever, maxillary dental pain, cough, and ear fullness or pressure
Nasal Obstruction may be reported as:
congestion, stuffiness, or blockage of nasal passages
Facial Pain, pressure, and fullness may be located..?
in the periorbital areas, anterior face, or as a diffuse or localized headache
Diagnosis
based on physical examination and starts with the completion of a history and physical exam focusing on the ears, nose, throat, teeth, sinuses, and chest
- during physical examination, the provider is looking for signs of inflammation, tenderness, firmness, or redness
- vital sign assessment to identify temperature elevation
During a physical examination, what is the provider looking for?
signs of inflammation, tenderness, firmness, or redness
Diagnostic Procedures
- physical exam (focusing on ears, nose, throat, teeth, sinuses, and chest)
- radiographical imaging of sinuses
- computed tomography (CT)
- magnetic resonance (MRI)
