A. Direct Visulaisation
B. Movements of Vocal cords seen better
C. No foreshortening of Vertical Axis
D. False cords and vocal cords are seen in the true perspective
Ans:B. Movements of Vocal cords seen better.
The image shown is of Direct Laryngoscopic Examination of Larynx.
Laryngoscopy is endoscopy of the larynx.

|Indirect Laryngoscopy||Direct Laryngoscopy|
|1||Inverted mirror image seen||Direct Visualisation|
|2||Vocal cords and false cords appear to be in one plane(flattened appearance)||False cors and Vocal cords are seen in the true perspective|
|3||Movements of Vocal cors seen better||Seen only if done under local anesthesia,orin a patient who has become light under general anesthesia|
|4||Office procedure||Operation theatre procedure|
|5||Anterior Commisure,Ventricule,Subglottis not visualised satisfactorily||Visualisation satisfactory|
|6||Foreshortening of vertical axis||No foreshortening|
|7||Good for diagnosis||Useful for Diagnosis,biopsy and surgical procedures|
