Vocal fold nodules are symmetrical free edge swelling typically located at the junction between anterior 1/3rd to posterior 2/3rd of the vocal fold. It is associated with phonotrauma caused by voice misuse, overuse, or abuse. Speech therapy is the preferred management for early/soft nodules with microlaryngeal surgery reserved for more mature/fibrous nodules. In some,early surgical intervention is justified.

It is important to address on voice rest during acute laryngitis. Additional phonotrauma may end-up with the risk of scar formation and further worsens the voice quality. Strict voice rest is advocated initially and later to limited usage.

Subepithelial haemorrhage secondary to phonotrauma. Patient was advised for complete voice rest initially for 3-5 days followed by limited and gradual voice use to normal. No other significant vocal fold pathology.

Abnormal capillaries predispose to vocal fold haemorrhage and may result in benign vocal fold lesions and scar formation. KTP and pulse-dye laser would
be ideal for the management of these lesions. However, bipolar diathermy at
low power setting is a good alternative if laser is not available.

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.
Reinke's oedema of polypoid corditis is a generalised oedema of the
subepithelial space with cumulation of gelatinous/myxomatous material.
It can occur unilaterally or bilaterally. Treament is by microsurgical
aspiration and alleviating the predisposing factor- usually smoking.

There is an abnormal capillary on the opposite vocal fold (blue arrow)
which needs to be treated as well. This vessels predispose to vocal fold haemorrhage with subsequent development of benign vocal lesions and scarring.
