Summary
Nasal decongestants increase nasal cavity volume and nasalance scores. However, changes in nasalance may not solely depend on nasal cavity volume, suggesting other contributing factors.
Area of Science:
- Otolaryngology
- Speech Science
- Acoustic Physiology
Background:
- Nasal cavity patency and volume influence voice acoustics.
- Understanding these relationships is crucial for voice production research.
Purpose of the Study:
- To investigate the impact of nasal decongestants on nasal volumes and nasalance.
- To explore the correlation between nasal volume changes and nasalance scores.
Main Methods:
- Acoustic rhinometry and nasometry were employed in 21 adult volunteers.
- Measurements were taken before and after nasal decongestant administration.
Main Results:
- Nasal decongestants significantly increased nasalance scores and all measured acoustic rhinometric parameters (e.g., cross-sectional areas, volumes).
- No significant correlation was found between alterations in nasalance scores and acoustic rhinometric parameters.
Conclusions:
- Nasal decongestion demonstrably increases both nasalance scores and nasal cavity volumes.
- The study suggests that factors beyond nasal cavity volume changes influence nasalance scores.

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...
01:15Respiratory Volumes
Respiratory volumes are crucial metrics, meticulously measured to quantify the air exchanged in and out of the lungs during various phases of the breathing cycle. These precise measurements are vital for assessing lung function, diagnosing respiratory conditions, and monitoring overall respiratory health. Each parameter provides specific insights into the mechanics of breathing and the functional capacity of the lungs.

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.

01:30Application of Integration: Problem Solving
The process of breathing involves the periodic intake and expulsion of air, known as the respiratory cycle, which typically lasts about five seconds. Modeling the volume of air inhaled into the lungs as a function of time provides insight into both the dynamics and efficiency of pulmonary ventilation. This volume is determined by integrating the airflow rate over time, which captures the cumulative effect of air entering the lungs.Sinusoidal Model of AirflowAirflow during respiration is not...
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.

01:03Olfactory 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...
