STRIDOR

STRIDOR: Excerpt from Algorithmic Diagnosis of Symptoms and Signs

Ask the Following Questions:

1. Is the patient an adult or a child? If the patient is a child, acute epiglottitis, acute laryngotracheitis, foreign body, congenital laryngeal stridor, laryngismus stridulus, and a retropharyngeal abscess should be considered. Diphtheria is rarely found nowadays. If the patient is an adult, myasthenia gravis, bulbar and pseudobulbar palsy, recurrent laryngeal palsy, pharyngitis, laryngotracheitis, carcinoma of the larynx or trachea, angioneurotic edema, foreign bodies, thyroid disorders, and disorders of the mediastinum should be considered.
2. Is it acute or gradual onset? The presence of stridor of acute onset would suggest acute epiglottitis, acute pharyngitis, laryngotracheitis, angioneurotic edema, retropharyngeal abscess, laryngismus stridulus, and foreign body.
3. Is there fever? The presence of fever would suggest acute laryngotracheitis, diphtheria, subacute thyroiditis, retropharyngeal abscess, and mediastinitis.
4. Are there abnormalities on the ear, nose, and throat examination? On ear, nose, and throat examination, the clinician may find pharyngitis, acute epiglottitis, a foreign body, tenderness of the thyroid suggesting thyroiditis, and thyroid masses.
5. Are there neurologic abnormalities on examination? Neurologic abnormalities may be found in myasthenia gravis, bulbar and pseudobulbar palsy, bilateral recurrent laryngeal nerve palsy, and comatose states.

DIAGNOSTIC WORKUP

Routine tests may include a CBC; sedimentation rate; smear and culture of material from the nose, throat, and sputum; x-ray of the chest and sinuses; and, in adults, an EKG. In adults also it might be wise to order a chemistry panel, thyroid profile, and VDRL test, depending on the clinical picture. Direct laryngoscopy can now be done in the office with the fiberoptic laryngoscope. In addition, fiberoptic bronchoscopy may be valuable. A Tensilon test may need to be done. An ear, nose, and throat specialist should be consulted before ordering expensive diagnostic tests. If there are neurologic signs, a neurologist should be consulted.
