Infection involving anterior larynx:
|D||All the above|
Ref. Scott's Brown 7th/ed pg 2267
Larynx is rarely involved. If Larynx is involved it presents as diffuse erythematous papules (secondary stage) and nodular infiltrates coalescing into painless ulcers (tertiary stage) with epiglottis and aryepiglottic folds being principally involved (. anterior part involved).
It is a slowly progressive disease with laryngeal involvement in less than 5% cases.
Laryngeal appearance is similar to that of T:B with suprglottic structures being involved primarily. anterior part involved.
As discussed earlier it involves posterior part more than anterior part. The parts being involved in the order:
1. Interarytenoid fold
2. Ventricular bands
3. Vocal cords
Hence - though less involved but anterior part of larynx may be involved.
