Summary
Nasal obstruction perception differs between nostrils. Rhinomanometry is key for right-sided obstruction, while acoustic rhinometry aids left-sided assessment, highlighting distinct nasal physiology.
Area of Science:
- Otolaryngology
- Respiratory Physiology
- Medical Imaging
Background:
- Nasal obstruction is a common complaint in nasal disease.
- Objective assessments like rhinomanometry and acoustic rhinometry are used for nasal patency.
- Limited research exists on the symmetry of left and right nostril airflow perception.
Purpose of the Study:
- To investigate the relationship between subjective and objective parameters of nasal airway in both left and right nostrils.
- To determine if left and right nostril perceptions of nasal obstruction are similar.
Main Methods:
- A prospective study of 101 patients with deviated nasal septum and chronic hypertrophic rhinitis.
- Subjective and objective nasal airway evaluation using visual analog scale, rhinomanometry, and acoustic rhinometry.
- Statistical analysis including ANOVA, f-tests, and simple regression.
Main Results:
- Significant differences in objective measurements between patient groups for right-sided airflow resistance (p<0.005) and left-sided minimal cross-sectional area and nasal cavity volume (p<0.05).
- Nasal airflow resistance is a key determinant of right-sided nasal obstruction.
- Minimal cross-sectional area and nasal cavity volume are key determinants of left-sided nasal obstruction.
Conclusions:
- Rhinomanometry is crucial for objectively measuring right-sided nasal obstruction.
- Acoustic rhinometry is vital for objectively measuring left-sided nasal obstruction.
- Human perception of nasal obstruction may differ between the left and right nostrils, warranting further investigation.

01:30Respiratory System Abnormal Finding I: Inspection and Percussion
Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.

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...
01:28Physical 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.

01:25Factors Affecting Perception
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.

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...
01:28Lateralization
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.
