Summary
Subjective nasal obstruction strongly correlates with objective nasal cavity measurements and airflow. Acoustic rhinometry (AR) and peak nasal inspiratory flow (PNIF) are valuable tools for assessing nasal complaints.
Area of Science:
- Otolaryngology
- Respiratory Medicine
- Medical Imaging
Background:
- The relationship between subjective nasal obstruction and objective nasal parameters remains controversial.
- Accurate assessment is crucial for managing nasal complaints and guiding treatment.
- Objective evaluation methods are needed to complement patient-reported symptoms.
Purpose of the Study:
- To evaluate the association between subjective nasal obstruction and objective nasal parameters.
- To assess the utility of acoustic rhinometry (AR) and peak nasal inspiratory flow (PNIF) in quantifying nasal obstruction.
- To investigate the correlation between patient-reported nasal obstruction and anatomical/physiological nasal measurements.
Main Methods:
- A cross-sectional study of 2,523 adult patients with chronic nasal or sleep-related complaints.
- Objective measurements included acoustic rhinometry (AR) for nasal cavity dimensions and peak nasal inspiratory flow (PNIF) for airflow.
- Subjective nasal obstruction was assessed using a visual analogue scale, with statistical analysis adjusted for confounding factors.
Main Results:
- Significant associations were found between subjective nasal obstruction and nasal cavity volumes (anterior and middle segments).
- Minimal cross-sectional areas in middle and overall nasal cavities, as well as PNIF, showed significant correlations with perceived obstruction.
- Associations with minimal cross-sectional areas in anterior segments were not statistically significant.
Conclusions:
- Subjective nasal obstruction is significantly associated with objective measures of nasal cavity volume, area, and airflow.
- Acoustic rhinometry (AR) and peak nasal inspiratory flow (PNIF) are validated, objective tools for evaluating subjective nasal obstruction.
- These objective measures aid in the clinical assessment and management of patients with nasal complaints.

01:24Nose 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...
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...

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.

01:27Upper Respiratory Drugs: Decongestants
Decongestants are a class of medications used primarily to alleviate nasal congestion, a common symptom resulting from allergies, colds, sinusitis, and other upper respiratory tract infections. These drugs work by activating α-adrenergic receptors, constricting small blood vessels in the nasal membranes. This action results in the opening of clogged nasal passages, thereby facilitating sinus drainage and relieving congestion.

01:29Anatomy 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.

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...
