J38.5
Laryngeal spasm
Clinical Classification Guidelines
Inclusion Terms
- Laryngismus (stridulus)
Medical Intelligence & Overview
Laryngeal spasm, medically known as laryngismus stridulus, is a sudden, involuntary contraction of the muscles around the larynx (voice box). This condition leads to a tightening or closing of the airway, which can cause difficulty in breathing, a characteristic high-pitched sound called stridor, and a feeling of distress. Although often temporary and resolving on its own, laryngeal spasms can be alarming due to their sudden onset and breathing difficulties. Recognizing the signs and understanding the underlying causes may help in managing episodes effectively and seeking appropriate medical care.
Causes & Symptoms
Clinical Causes: Allergic reactions leading to airway inflammation or swelling Reflex responses to acid reflux or gastroesophageal reflux disease (GERD) Respiratory infections affecting the upper airway Environmental irritants such as smoke, dust, or chemical fumes Anxiety, panic attacks, or emotional stress Exposure to cold air or sudden changes in temperature Inhalation of foreign bodies or food particles Neurological conditions affecting muscle control Use of certain medications which may impact muscle tone Structural abnormalities of the larynx or airway
Key Symptoms: Sudden onset of difficulty breathing High-pitched or strained sound during inspiration (stridor) Crowing or barking cough Feeling of tightness or constriction in the throat Pale or bluish coloration of the lips or face (cyanosis) Anxiety or panic feelings during episodes In some cases, loss of consciousness if breathing is severely compromised
Diagnostic & Treatment
Diagnosis Path: Medical history assessment focusing on episode triggers and frequency Physical examination of the throat and respiratory system Listening to breathing sounds with a stethoscope Imaging tests such as X-rays or laryngoscopy to inspect airway structures Pulmonary function tests if chronic airway issues are suspected Allergy testing if allergic causes are suspected Referral to specialists such as an otolaryngologist or allergist for detailed evaluation
Treatment Protocols: Immediate management during an episode, which may include calming the patient and assisting with breathing if necessary Administering medications such as antihistamines or corticosteroids for allergic causes Using bronchodilators if bronchospasm is involved Treating underlying conditions like reflux with dietary changes or medications Avoiding known triggers and irritants Breathing techniques and reassurance to reduce anxiety during episodes Long-term management may involve allergy control measures or surgical options if structural abnormalities are diagnosed Emergency medical intervention if breathing difficulties worsen or do not resolve
