In the following video, a technique of laryngeal examination by using 70 degrees rigid endoscope is shown. Right vocal fold polyp (arrow) had caused this patient to have hoarse voice, pitch break and fatigue. (E - epiglottis)
Vocal fold polyp is a unilateral mass lesion usually arising near its free edge. It can be sessile or pedunculated. There might be contralateral vocal fold reactions usually a thickened epithelium which resolves spontaneously upon microsurgical excision of the primary lesion.

Prolonged and repetitive voice over-used or abuse have detrimental effect on vocal folds especially when voice projection is needed in a very noisy background. In this video, left vocal fold polyp has formed (white arrow) with opposite vocal fold thickening seen and evidence of recent bleeding into superficial vocal fold layer (green arrow with yellowish tinge underneath the vocal folds lining on both sides). The mucosa of arytenoids and posterior commissure appeared swollen, reddish and oedematous due to coexisting untreated reflux laryngitis (blue interrupted line).
In this video, a huge a obstucting vocal fold polyp is seen between the vocal folds. It was successfully excised by using carbon dioxide (CO2) laser and his laryngeal symtoms (hoarse voice, difficulty in breathing, and throat irritations) recovered to normal.
