Summary
This systematic review identified common internal nasal septal deviation classifications. Most systems describe C-shaped, S-shaped, and their reverse forms in key dimensions, aiding research.
Area of Science:
- Otolaryngology
- Medical Imaging
- Anatomy
Background:
- Internal nasal septal deviation is a common condition.
- Existing classification systems lack standardization, hindering clinical and research efforts.
Purpose of the Study:
- To systematically review and summarize international literature on internal nasal septal deviation classification systems.
- To provide a consolidated overview for clinical application and future research.
Main Methods:
- Systematic literature review adhering to PRISMA guidelines.
- Searched four databases, including PubMed/MEDLINE, up to December 16, 2015.
- Screened 952 articles, with 15 meeting eligibility criteria for final analysis.
Main Results:
- Identified classification systems describing C-shaped, S-shaped, reverse C-shaped, and reverse S-shaped deviations.
- Deviations were categorized in cephalocaudal and anteroposterior dimensions.
- Included systems using computed tomography, predefined locations, severity grading, and evaluation of spurs/perforations.
Conclusions:
- The majority of current classification systems can be summarized by C-shaped or S-shaped deviations in anteroposterior and cephalocaudal dimensions.
- Standardized terminology, including predefined points for imaging studies, can facilitate future research and clinical communication.

01:24Nose and Nasal Cavity
15.3K
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
712
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...

5.0K
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.

6.3K
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.

4.8K
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:

01:30Pulmonary Hypertension: Classification and Pathogenesis
822
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...
