Tubercular laryngitis affects primarily
Correct Answer: Posterior commissure of larynx
Description: The disease affects posterior pa of larynx more than anterior. Pas affected are (i) interarytenoid fold (ii) ventricular bands (iii) vocal cords and (iv) epiglottis, in that order. Tubercle bacilli, carried by sputum from the bronchi, settle and penetrate the intact laryngeal mucosa paicularly in the interarytenoid region (bronchogenic spread). This leads to the formation of submucosal tubercles which may later caseate and ulcerate. Ref: PL Dhingra 6th edition of Ear, Nose and Throat; Pg no 293
