- TUBERCULOSIS OF LARYNX
- It is almost always secondary to pulmonary tuberculosis
- Disease affects posterior part of larynx more than anterior.
- Parts affected are:
- interarytenoid fold (most common ) MCQ
- ventricular bands,
- vocal cords
- Weakness of voice is the earliest symptom followed by hoarseness. (MCQ)
- Laryngeal Examination
- Hyperaemia of the vocal cord in its whole extent or confined to posterior part with impairment of adduction is the first sign. .(MCQ)
- Swelling in the interarytenoid region giving a mamillated appearance.(MCQ)
- Ulceration of vocal cord giving mouse-nibbled appearance. .(MCQ)
- Superficial ragged ulceration on the arytenoids and interarytenoid region.
- Granulation tissue in interarytenoid region or vocal process of arytenoid.
- Pseudoedema of the epiglottis “turban epiglottis”..(MCQ)
- Swelling of ventricular bands and aryepiglottic folds.
- Marked pallor of surrounding mucosa
- LUPUS OF THE LARYNX
- It is an indolent tubercular infection
- associated with lupus of nose and pharynx.
- Unlike tuberculosis of larynx which mostly affects posterior parts, lupus involves the anterior part of larynx. (MCQ)
- Epiglottis is involved first and may be completely destroyed by the disease. (MCQ)
- The lesion spreads to aryepiglottic folds and sometimes to ventricular bands.
- Lupus of larynx is a painless and often an asymptomatic condition and may be discovered on routine laryngeal examination in cases of lupus of nose.
- There is no pulmonary tuberculosis.
- Treatment is antitubercular drugs.
- Prognosis is good.
Tuberculosis of Larynx
