Summary
This study reviews supraglottoplasty techniques for laryngomalacia, proposing a new classification system. The proposed system simplifies surgical variations into three types to improve reporting and future research.
Area of Science:
- Otolaryngology
- Pediatric Surgery
Background:
- Laryngomalacia is a common congenital condition causing upper airway obstruction.
- Supraglottoplasty is a surgical intervention to address severe laryngomalacia.
- Variations in surgical techniques and reporting hinder outcome assessment.
Purpose of the Study:
- To systematically review published supraglottoplasty techniques for laryngomalacia.
- To develop a standardized classification system for supraglottoplasty procedures.
Main Methods:
- Systematic literature search of multiple databases (PubMed/MEDLINE and others).
- Independent review of 231 identified articles.
- Cataloging and categorization of surgical techniques and sub-sites operated on.
Main Results:
- 53 articles detailing supraglottoplasty in 1669 patients were analyzed.
- Significant heterogeneity in technique descriptions was found, with 77% of cases lacking sufficient detail for outcome assessment.
- A classification system was developed: Type 1 (Debulking of arytenoids), Type 2 (Division of aryepiglottic folds), Type 3 (Epiglottis surgery).
Conclusions:
- The review identified numerous supraglottoplasty variations.
- A new, simplified three-type classification system for supraglottoplasty was proposed.
- This classification aims to standardize surgical reporting, facilitating communication and future research in laryngomalacia treatment.

01:01Classification of Titrimetric Analysis Based on Reaction Types
1.8K
Titrimetric analysis in solution chemistry involves measuring the volume of solutions and is often called volumetric analysis. The standard solution of known concentration in the burette is called the titrant, whereas the solution of unknown concentration in the flask is called the analyte, or titrand. Titrimetric analyses can be classified into four types based on the reactions between the titrant and analyte.

04:00Periodic Classification of the Elements
59.3K
The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table, a periodic recurrence of similar electron configurations in the outer shells of these elements is observed. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom...

2.4K
Forces play a crucial role in the study of physics and engineering. They are essential in describing the motion, behavior, and equilibrium of objects in the physical world. Forces can be classified based on their origin, type, and direction of action.
Contact and non-contact forces are two of the most widely used categories of forces. As the name suggests, contact forces require physical contact between two objects to act upon each other. Examples of contact forces include frictional,...

01:30Classification of Neurotransmitters
5.3K
Neurotransmitters play a crucial role in the communication between neurons in the autonomic nervous system. Neurons in the autonomic nervous system can be cholinergic or adrenergic depending on the neurotransmitters synthesized. Cholinergic neurons use acetylcholine as their primary neurotransmitter. This includes all the preganglionic fibers of the sympathetic and pre- and postganglionic fibers of the parasympathetic nervous systems. In addition, neurons of the somatic nervous system also use...

01:30Classification of Leukocytes
6.0K
Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...

01:17Classification of Illness
8.8K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...
