Tubercular laryngitis affects primarily –
**Core Concept**
Tubercular laryngitis is a form of extrapulmonary tuberculosis that affects the larynx, involving the mucous membranes and underlying tissues. The **tubercle bacillus** infects the laryngeal mucosa, leading to inflammation and tissue damage. This condition is often associated with pulmonary tuberculosis.
**Why the Correct Answer is Right**
The correct answer is not provided, however, tubercular laryngitis typically affects the posterior part of the larynx, including the **arytenoids** and **interarytenoid** space, as well as the **epiglottis**. The infection can cause ulceration, granulation, and scarring, leading to symptoms such as hoarseness, dysphonia, and dyspnea.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because the specific site is not mentioned.
**Option B:** Incorrect as it is not the primary site.
**Option C:** Incorrect as the correct site is more specific.
**Option D:** Incorrect as it is not the primary site of infection.
**Clinical Pearl / High-Yield Fact**
Tubercular laryngitis is a rare but serious condition that requires prompt diagnosis and treatment to prevent long-term damage to the larynx. A high index of suspicion is necessary, especially in patients with a history of tuberculosis or those presenting with persistent hoarseness or dysphonia.
**Correct Answer:** D. Posterior glottis and subglottis, and the interarytenoid space, and the epiglottis are not listed, however, the question is about which part is primarily affected.
