Which of the following is true about Torus tubarius?
Ans. c. Tubal elevation in lateral wall of nasopharynxRef: Disease of Ear, Nose and Throat by Dhingra; 7th Ed Page No- 61, 277-84 and Logan Turners Disease of the Nose, Throat and Ear 11th Ed; Page No-154Nasopharynx part of the pharynx extends from the skull base to the soft palate and communicates with the nose anteriorly through the posterior choanae. In its posterior wall is a collection of lymphoid tissue, the pharyngeal tonsil or adenoids.On the lateral wall is the opening of the auditory (eustachian) tube, which is surrounded superiorly, posteriorly and inferiorly by a prominent ridge, the torus, formed by the medial end of the cartilaginous auditory tube.It is 1-1.25 cm behind the inferior turbinate.Transnasal endoscopic appearance of the nasopharynxRathke's pouch is represented by a dimple, high in nasopharynxPosterior to this is a slit-like space, which is the fossa of Rosenmiiller.Fossa of Rosenmiiller is the most common site for origin of nasopharyngeal carcinoma.Inflammation of nasopharyngeal bursa is called nasopharyngeal bursitis.
