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: Hitselberger's sign is seen in?

Acoustic neuroma. ***Acoustic neuroma*** - Hitselberger's sign is an area of **hypoesthesia** or **anesthesia** in the **posterosuperior portion of the external auditory canal**. - Acoustic neuromas (vestibular schwannomas) arise from the **vestibular portion of CN VIII** in the internal auditory canal. - This sign results from involvement of the **sensory fibers of the nervus intermedius** (sensory branch associated with the facial nerve) due to close anatomical proximity in the cerebellopontine angle. - This symptom, also known as the **"ear canal sign,"** is relatively specific for acoustic neuroma. *Glomus Tumour* - Glomus tumors are **highly vascular benign tumors** of the **middle ear** that present with **pulsatile tinnitus** and conductive hearing loss. - While they can affect cranial nerves, Hitselberger's sign is not a characteristic presentation. *Nasal angiofibroma* - Nasal angiofibromas are **benign, highly vascular tumors** found in the **nasopharynx**, primarily affecting adolescent males. - They typically present with **epistaxis** and **nasal obstruction** and do not cause Hitselberger's sign. *Acute suppurative otitis media* - Acute suppurative otitis media is an **infection of the middle ear** causing earache, fever, and hearing loss. - It does not involve the cerebellopontine angle or sensory innervation of the external auditory canal in a way that would lead to Hitselberger's sign.

Q: Which perforation of the tympanic membrane is most commonly seen with tubotympanic CSOM?

Central. ***Central*** - A **central perforation** of the tympanic membrane is the most common type seen in **tubotympanic chronic suppurative otitis media (CSOM)**. - This type of perforation involves the **pars tensa** of the tympanic membrane, leaving an intact annulus. *Anterosuperior* - While perforations can occur anywhere, an **anterosuperior perforation** is not the hallmark of tubotympanic CSOM. - This location does not specifically correlate with the characteristic inflammatory patterns seen in tubotympanic disease. *Posterosuperior* - A **posterosuperior perforation** is more often associated with **atticoantral CSOM** due to **cholesteatoma formation**. - **Cholesteatoma** typically begins in the pars flaccida or posterosuperior pars tensa, which is different from tubotympanic CSOM. *Posteroinferior* - A **posteroinferior perforation** is not the most typical presentation for tubotympanic CSOM. - This location does not specifically differentiate it from other forms of otitis media or reflect the primary pathology of tubotympanic disease.

Q: Most common cause of otitis externa is

Bacterial infection. ***Bacterial infection*** - The most common pathogens causing **otitis externa** are bacteria, primarily **Pseudomonas aeruginosa** and **Staphylococcus aureus**. - This condition, often called "swimmer's ear," is favored by moisture in the ear canal, which creates a conducive environment for bacterial growth. *Fungal infection* - While fungal infections (otomycosis) can cause otitis externa, they are **less common** than bacterial causes. - Fungi like *Aspergillus* and *Candida* are typically involved, often in immunocompromised individuals or after prolonged antibiotic use. *Seborrheic disease* - **Seborrheic dermatitis** can affect the ear canal and surrounding skin, leading to flaking, itching, and inflammation. - However, it is a primary skin condition and does not directly cause infectious otitis externa, although it can predispose to secondary infections. *Herpes Zoster* - **Herpes zoster oticus** (Ramsay Hunt syndrome) is a viral infection affecting the facial nerve, causing a painful rash, facial paralysis, and hearing loss. - It is a specific viral etiology with distinct neurological symptoms and is not a common cause of general otitis externa.
