The Cormack–Lehane system classifies views obtained by direct laryngoscopy based on the structures seen. It was initially described by R.S. Cormack and J. Lehane in 1984 as a way of simulating potential scenarios that trainee anaesthetists might face. [1] A modified version that subdivided Grade 2 was initially described in 1998. [2]
A systematic review of 42 studies, with 34,513 participants, found that the modified Mallampati score is a good predictor of difficult direct laryngoscopy and intubation, but poor at predicting difficult bag mask ventilation.
Anatomical parts seen during laryngoscopy. Direct laryngoscopy is carried out (usually) with the patient lying on their back; the laryngoscope is inserted into the mouth on the right side and flipped to the left to trap and move the tongue out of the line of sight, and, depending on the type of blade used, inserted either anterior or posterior to the epiglottis and then lifted with an upwards ...

Based on the results of the laryngoscopy, Reinke's edema can be classified using a standardized system set in place by Yonekawa. This system characterizes the disease based on severity. [12] Yonekawa Classification: [12] Grade I – Lesions contact the anterior third of the vocal fold; Grade II – Lesions contact the anterior two-thirds of the ...
Structures of the larynx as viewed during laryngoscopy. The leaf-like epiglottis is shown as number '3'. The leaf-like epiglottis is shown as number '3'. Other structures: 1=vocal folds, 2=vestibular fold, 3=epiglottis, 4=plica aryepiglottica, 5=arytenoid cartilage, 6=sinus piriformis, 7=dorsum of the tongue
The temperature drops from 6 degrees to 3 to 1. A road sign reads “Pass With Care.” Cell phone bars vanish one by one, until there are none. Fischer and his mother view these monthly trips as a chance to make up for lost time. Anderson gave birth to him 15 years after her first-born son and a decade after her daughter.
Esophagoscopy and laryngoscopy can give direct view of lumens. Esophageal motility study is useful in cases of esophageal achalasia and diffuse esophageal spasms. Exfoliative cytology can be performed on esophageal lavage obtained by esophagoscopy. It can detect malignant cells in early stage.
