Laryngoscopy

LARYNGOSCOPY  

• Acute laryngeal spasm during indirect laryngoscopy is seen in Acute epiglottitis
• During laryngoscopy and endo-tracheal intubation  The laryngoscope is lifted upwards levering over the upper incisors maneuver is not performed
• Anaesthesia used in microlaryngoscopy is Pollarad tube with infiltration block
• In a direct laryngoscopy Cricothyroid, Lingual surface of epiglottis & Arytenoids can be visualized
• Hidden areas of larynx viz. infrahyoid epiglottis, anterior commissure, ventricles and subglottic region and apex of pyriform fossa are difficult to visualize by indirect laryngoscopy.
• Microlaryngoscopy was started by Kleinsasser
• The procedure that should precede microlaryngoscopy is Rhinoscopy
• laryngoscopy showing diagnosis  of multiple juvenile papillo-matosis of the larynx should be followed by Microlaryngoscopic surgery
• lntra ocular pressure rises in  Intubation & laryngoscopy
