Summary
A new classification system for nasal obstruction was developed using the Nasal Obstruction Symptom Evaluation (NOSE) survey. This system categorizes obstruction severity, aiding patient care and research.
Area of Science:
- Otolaryngology
- Facial Plastic Surgery
- Quality of Life Assessment
Background:
- Nasal airway obstruction is a frequent symptom in otolaryngology and facial plastic surgery.
- Multiple factors can contribute to nasal obstruction, necessitating thorough evaluation.
Purpose of the Study:
- To develop a classification system for nasal obstruction.
- Utilize a validated, subjective quality-of-life instrument for classification.
Main Methods:
- Retrospective analysis of patient responses from the Nasal Obstruction Symptom Evaluation (NOSE) instrument.
- Development of a classification system using receiver operating characteristic curve analysis.
- Categorization of nasal obstruction severity based on NOSE scores.
Main Results:
- Analysis included data from 345 patients.
- A NOSE score of 30 effectively distinguished between patients with and without nasal obstruction.
- Established severity classes: mild (5-25), moderate (30-50), severe (55-75), and extreme (80-100).
Conclusions:
- The NOSE scale is crucial for assessing nasal obstruction symptoms.
- The proposed classification enhances patient care by providing a severity framework.
- This system will improve understanding of patient populations and treatment effects in research.

01:29Suctioning 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.

01:26Asthma-II: Pathophysiology and Classification
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

01:24Asthma-III: Symptoms and Complications
Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

01:30Epistaxis
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...

01:28Physical Assessment of the Respiratory Tract I: Health History
Physical assessment of the respiratory tract is critical to patient care. It allows healthcare professionals to identify and manage various respiratory conditions. The process involves a combination of subjective and objective data collection.
Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.

01:03Olfactory Receptors: Location and Structure
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
