Definition

Noun: * A severe respiratory infection: "laryngotracheobronchitis" is a medical term for the inflammation of the larynx (voice box), trachea (windpipe), and bronchial passageways (the main airways leading into the lungs). It is a condition that can cause significant breathing difficulties.

Usage

• "Laryngotracheobronchitis" is a highly specific clinical term used primarily in medical contexts by healthcare professionals.
• It describes a serious, extensive form of croup, particularly in young children, where the inflammation spreads beyond the larynx.
• The term is typically used in diagnoses, medical reports, and clinical discussions.

Examples

• The infant was hospitalized with a severe case of laryngotracheobronchitis.
• Laryngotracheobronchitis often presents with a barking cough, stridor, and respiratory distress.
• The doctor explained that the inflammation had progressed to laryngotracheobronchitis.

Advanced Usage

• The term can be abbreviated in clinical notes as LTB.
• It is often differentiated from simple "laryngitis" or "tracheitis" by the involvement of all three anatomical structures (larynx, trachea, bronchi).

Variants and Related Words

• Croup (n): A common, broader term for laryngeal inflammation that often implies some tracheal involvement; laryngotracheobronchitis is a severe form of croup.
• Laryngitis (n): Inflammation specifically of the larynx.
• Tracheitis (n): Inflammation specifically of the trachea.
• Bronchitis (n): Inflammation specifically of the bronchial tubes.

Synonyms
