Laryngoscopy an instrumental method of examining the larynx through the oral cavity. There are two types of laryngoscopy: indirect (mirror) and direct. Indirect laryngoscopy is performed with a round laryngeal mirror (16 to 27 mm in diameter) in a metal rim attached to a metal rod at an angle of 120°. A frontal reflector is used to direct a light beam to the laryngeal mirror from an artificial source. Direct laryngoscopy is performed with special medical instruments, or laryngoscopes, which allow one to examine the larynx directly. The method is used in cases where the indirect approach proves inadequate or where the site of examination or surgical intervention proves inaccessible. Direct laryngoscopy is performed under narcosis where indicated. laryngoscopy
Laryngoscopy DefinitionLaryngoscopy refers to a procedure used to view the inside of the larynx (the voice box).DescriptionThe purpose and advantage of seeing inside the larynx is to detect tumors, foreign bodies, nerve or structural injury, or other abnormalities. Two methods allow the larynx to be seen directly during the examination. In one, a flexible tube with a fiber-optic device is threaded through the nasal passage and down into the throat. The other method uses a rigid viewing tube passed directly from the mouth, through the throat, into the larynx. A light and lens affixed to the endoscope are used in both methods. The endoscopic tube may also be equipped to suction debris or remove material for biopsy. Bronchoscopy is a similar, but more extensive procedure in which the tube is continued through the larynx, down into the trachea and bronchi.PreparationLaryngoscopy is done in the hospital with a local anesthetic spray to minimize discomfort and suppress the gag reflex. Patients are requested not to eat for several hours before the examination.AftercareIf the throat is sore, soothing liquids or lozenges will probably relieve any temporary discomfort.RisksThis procedure carries no serious risks, although the patient may experience soreness of the throat or cough up small amounts of blood until the irritation subsides.Normal resultsA normal result would be the absence of signs of disease or damage.Abnormal resultsAn abnormal finding, such as a tumor or an object lodged in the tissue, would either be removed or described for further medical attention.Key termsEndoscopic tube — a tube that is inserted into a hollow organ permitting a physician to see the inside it.laryngoscopy [lar″ing-gos´kah-pe] visual examination of the larynx with a laryngoscope. With direct visualization, the patient is given a mild sedative to promote relaxation, because the procedure, though not uncomfortable, may be frightening and exhausting. Immediately before insertion of the laryngoscope, the throat is anesthetized locally with cocaine spray. Following the procedure, fluids and foods are withheld until the effects of the anesthetic have worn off and the reflex" >gag reflex has returned. Visualization may also be indirect, which means examination is done by observation of the reflection of the larynx in a laryngeal mirror. adj., adj laryngoscop´ic.lar·yn·gos·co·py (lar'ing-gos'kŏ-pē), Inspection of the larynx by means of the laryngoscope.laryngoscopy (lăr′ĭn-gŏs′kə-pē)n.
