NEET-PG 2015 - ENT PYQs Practice Questions

Q: All of the following are features of a nasal foreign body except:

Nasal polyps. ***Nasal polyps*** - While chronic inflammation can lead to nasal polyps, they are **not a direct or acute feature** of a nasal foreign body. - Nasal foreign bodies typically present with more immediate and obstructive symptoms rather than polyp formation. *Epistaxis* - A nasal foreign body can **irritate and traumatize the delicate nasal mucosa**, leading to bleeding. - This is a common symptom, especially if the foreign body is sharp or has been in place for some time. *Nasal obstruction* - The presence of any object in the nasal cavity will inevitably cause some degree of **physical blockage of airflow**. - This is one of the most common presenting symptoms, particularly in children. *Foul smelling discharge* - If a foreign body remains in the nasal cavity for an extended period, it can lead to **stasis of secretions and secondary bacterial infection**. - This infection often results in a **purulent, unilateral, and foul-smelling discharge**.

Q: Stapedius pulls stapes in which direction?

Posterior. ***Posterior*** - The **stapedius muscle** attaches to the **posterior surface of the stapes neck**. - Contraction of the stapedius muscle pulls the stapes **posteriorly and laterally** (posterolaterally), tilting the footplate away from the oval window and reducing sound transmission. - This action dampens excessive vibrations and protects the inner ear from loud sounds as part of the **acoustic reflex**. *Anterior* - Pulling the stapes anteriorly would push the footplate further into the **oval window**, which would increase sound transmission rather than dampen it. - No muscle pulls the stapes anteriorly in the context of the **acoustic reflex**. *Superior* - The stapedius muscle's action is primarily along the **posterolateral axis**, not superiorly. - Pulling superiorly would not effectively dampen sound vibrations or protect the inner ear from acoustic trauma. *Inferior* - The anatomy and function of the stapedius muscle do not support an inferior pulling action. - The stapedius acts to stabilize and retract the stapes **posterolaterally**, not inferiorly.

Q: In Caldwell Luc operation, the approach is through the?

Opening of maxillary antrum through gingivolabial approach. ***Opening of maxillary antrum through gingivolabial approach*** - The **Caldwell-Luc operation** involves creating a surgical window in the anterior wall of the **maxillary sinus** via an incision in the **gingivolabial sulcus** (also called sublabial sulcus). - This **open surgical approach** through the canine fossa provides direct access to the antrum for removal of pathology, foreign bodies, or drainage of chronic infections. - The incision is made above the canine tooth, and the anterior wall of the maxilla is fenestrated. *Transnasal endoscopic approach through the middle meatus* - This describes **functional endoscopic sinus surgery (FESS)**, which is a minimally invasive endoscopic technique, not the traditional open Caldwell-Luc procedure. - While FESS accesses the maxillary sinus through the natural ostium or by creating a middle meatal antrostomy, it is a fundamentally different approach. - Caldwell-Luc is an **extranasal, open approach**, whereas FESS is an **intranasal, endoscopic approach**. *Through the sphenopalatine recess for maxillary sinus access* - The **sphenopalatine recess** is primarily associated with endoscopic approaches to the sphenoid sinus or procedures involving the **pterygopalatine fossa**, not the Caldwell-Luc approach. - This approach does not involve breaching the anterior wall of the maxillary sinus through the canine fossa. *Accessing the maxillary sinus via superior meatus* - The **superior meatus** is not used for accessing the maxillary sinus in any standard surgical approach. - The natural ostium of the maxillary sinus opens into the **middle meatus**, not the superior meatus. - The superior meatus drains the posterior ethmoid cells, not the maxillary sinus.

Q: The artery which leads to bleeding in Woodruff's area is?

Sphenopalatine artery. ***Sphenopalatine artery*** - **Woodruff's area** is located on the posterior lateral wall of the nasal cavity, specifically a plexus of veins and arteries inferior to the posterior end of the inferior turbinate. - Bleeding from this region, often associated with **posterior epistaxis**, typically involves branches of the **sphenopalatine artery**. *Anterior ethmoidal artery* - The **anterior ethmoidal artery** is primarily involved in **anterior epistaxis**, supplying Kiesselbach's plexus on the nasal septum. - It does not contribute significantly to bleeding from Woodruff's area on the posterior lateral wall. *Greater palatine artery* - The **greater palatine artery** supplies the hard and soft palate and a small portion of the nasal floor. - It is not a major contributor to bleeding in Woodruff's area, which is located more superiorly and posteriorly on the lateral nasal wall. *Superior labial artery* - The **superior labial artery** is a branch of the facial artery, primarily supplying the upper lip and philtrum. - While it contributes to the vascular supply of the anterior nasal septum, it is not involved in bleeding from Woodruff's area.

Q: All of the following are causes of perforation of the cartilaginous part of the nasal septum except?

Syphilis. ***Syphilis*** - **Syphilis** typically causes perforation of the **bony part** of the nasal septum, particularly the vomer and perpendicular plate of the ethmoid bone, due to chronic granulomatous inflammation. - The cartilaginous septum is generally less affected by syphilis in terms of perforation, although early mucosal involvement can occur. *Trauma* - **Trauma** (e.g., nose picking, septal surgery, foreign body insertion) is a common cause of **perforation of the cartilaginous nasal septum**. - Such injuries can lead to localized necrosis and subsequent perforation due to disruption of the blood supply to the septal cartilage. *Tuberculosis* - **Tuberculosis** can cause **granulomatous inflammation** and necrosis, leading to perforation of the **cartilaginous nasal septum**. - This is part of extrapulmonary tuberculosis and can present with chronic nasal obstruction and discharge. *Leprosy* - **Leprosy** (Hansen's disease) is known to cause severe destruction of nasal structures due to chronic inflammation, including perforation of the **cartilaginous nasal septum**. - The specific bacteria cause granulomatous lesions that erode the cartilage over time.
