Summary
Lateral nasal wall collapse, often seen during breathing, does not correlate with a patient's nasal obstruction symptoms. This finding challenges its use as a sole indicator for nasal valve surgery.
Area of Science:
- Otolaryngology
- Nasal Physiology
- Surgical Assessment
Background:
- Lateral nasal wall collapse during forced inspiration is a common clinical sign.
- It is often considered indicative of nasal obstruction and a criterion for nasal valve surgery.
Purpose of the Study:
- To investigate the relationship between the degree of lateral nasal wall collapse and subjective nasal obstruction.
- To identify factors associated with lateral nasal wall collapse.
Main Methods:
- Lateral nasal wall collapse was quantified by the reduction in the lateral nasal wall triangle (LNWT) area during forced inspiration.
- LNWT area ratios were compared between patient and control groups.
- The correlation between lateral nasal wall collapse and clinical factors (symptom scores, nasal valve angles, skin thickness) was evaluated.
Main Results:
- The LNWT area ratio was significantly different between patients and controls (0.96 vs. 0.83, P=.001).
- No significant relationship was found between the degree of lateral nasal wall collapse and symptom scores (Nasal Obstruction Symptom Evaluation [NOSE] and Visual Analog Scale [VAS]).
- Nasal valve angle and skin thickness were also not associated with the degree of lateral nasal wall collapse.
Conclusions:
- Lateral nasal wall collapse is not directly related to a patient's subjective nasal obstruction.
- The clinical significance of lateral nasal wall collapse as a sole indicator for nasal obstruction or nasal valve surgery needs further re-evaluation.

01:27Cranial Bones: Lateral View
2.5K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:24Nose and Nasal Cavity
4.2K
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...

01:03Olfactory Receptors: Location and Structure
9.5K
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...

01:30Epistaxis
248
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...

01:29Suctioning the Nasopharyngeal Airway
838
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.

01:26Pneumothorax-I
319
A pneumothorax is a condition where air builds up in the space between the lung and the chest wall, causing the lung to collapse. This condition arises when air enters the space between the parietal and visceral pleura, disrupting the negative pressure essential for lung inflation. This can lead to a partial or complete collapse of the lung.
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
