NEET-PG 2013 - ENT Practice Questions

Q: Which of the following conditions is associated with objective tinnitus?

Glomus tumor. ***Glomus tumor*** - A glomus tumor is a **vascular tumor** that can cause turbulent blood flow, leading to a pulsatile, objective tinnitus that can be heard by an examiner. - The sound is often described as a **thumping or whooshing** sound synchronous with the patient's heartbeat. *Ménière's disease* - **Ménière's disease** is associated with subjective tinnitus, a ringing or roaring sensation perceptible only to the patient. - It is characterized by the triad of **vertigo, fluctuating hearing loss, and tinnitus**. *Acoustic neuroma* - An acoustic neuroma (vestibular schwannoma) typically causes **unilateral, subjective tinnitus**, often described as a high-pitched ringing. - It is a benign tumor on the **vestibulocochlear nerve** and is also associated with sensorineural hearing loss and balance issues. *Ear wax* - **Impacted ear wax** can cause subjective tinnitus due to its interference with sound conduction and resonance within the ear canal. - The tinnitus is not typically audible to an examiner, making it a **subjective finding**.

Q: Electrode of cochlear implant is placed in:

Scala tympani. ***Scala tympani*** - The electrode array of a **cochlear implant** is carefully inserted into the **scala tympani** of the cochlea. - This placement allows the electrodes to directly stimulate the **spiral ganglion neurons**, bypassing damaged hair cells and transmitting electrical signals to the auditory nerve. *Horizontal semicircular canal* - The **horizontal semicircular canal** is part of the **vestibular system**, responsible for sensing angular head movements, not hearing. - Placing an electrode here would cause **vestibular dysfunction** and would not restore hearing. *Scala media* - The **scala media** (cochlear duct) contains the **organ of Corti** and **endolymph**, which has a high potassium concentration. - Inserting an electrode here would damage the delicate structures essential for natural sound transduction and could lead to electric potential imbalances. *Scala vestibuli* - The **scala vestibuli** is filled with **perilymph** and receives sound vibrations from the stapes. - While it's adjacent to the scala tympani, the **scala tympani** offers a safer and more direct path for optimal electrode insertion with less trauma to the sensory structures.

Q: Rosen's incision is used for which surgical procedure?

Stapedectomy. ***Stapedectomy*** - **Rosen's incision** is a **curved incision in the posterior ear canal** specifically used for **stapedectomy** surgery. - This incision provides excellent exposure of the **middle ear** and particularly the **stapes footplate** for otosclerosis surgery. - The incision extends from approximately **6 o'clock to 12 o'clock** position in the posterior canal, allowing the tympanomeatal flap to be elevated. *Tympanoplasty* - **Tympanoplasty** (repair of perforated tympanic membrane) can use various incisions including **permeatal**, **endaural**, or **postauricular** approaches. - While transmeatal approaches are used, they are not specifically termed "Rosen's incision," which is reserved for stapes surgery. *Septoplasty* - **Septoplasty** is a nasal procedure for correcting a deviated septum using incisions like **hemitransfixion** or **Killian's incision**. - This procedure involves the **nasal septum**, not the ear canal. *Tonsillectomy* - **Tonsillectomy** is performed entirely through an **oral approach** for removal of palatine tonsils. - No external or ear canal incisions are involved.

Q: Moure's sign (lateral displacement of the soft palate) is associated with which of the following conditions?

Peritonsillar abscess. ***Peritonsillar abscess (Quinsy)*** - **Moure's sign** refers to the **lateral displacement of the soft palate** toward the affected side, which is a classic finding in **peritonsillar abscess**. - This occurs due to the **accumulation of pus** between the tonsillar capsule and the superior constrictor muscle, causing the soft palate to bulge and deviate. - Other features include **severe throat pain**, trismus, drooling, and a "hot potato" voice. *Laryngeal carcinoma* - **Laryngeal carcinoma** presents with **hoarseness**, dysphagia, and potential airway obstruction. - While laryngeal examination may show mass lesions or vocal cord fixation, **soft palate displacement is not a feature** of laryngeal malignancy. *Chronic tonsillitis* - **Chronic tonsillitis** involves recurrent throat infections with tonsillar hypertrophy and cryptic debris. - It does **not cause acute soft palate displacement** like peritonsillar abscess does. *Acute epiglottitis* - **Acute epiglottitis** is characterized by **supraglottic inflammation** causing severe dysphagia, drooling, and stridor. - The pathology is at the **epiglottis level**, not the peritonsillar space, so **Moure's sign is absent**.

Q: Which objective test is most effective for examining adenoids?

Posterior rhinoscopy. ***Posterior rhinoscopy*** - This method allows for **direct visualization of the nasopharynx** where the adenoids are located, using a post-nasal mirror or flexible endoscope. - It provides an **objective assessment** of adenoid size, extent, and any associated obstruction by direct observation. - Among the clinical examination methods listed, this is the most effective for **visualizing adenoid tissue** and assessing hypertrophy. - In modern practice, flexible nasopharyngoscopy has largely replaced mirror examination, but posterior rhinoscopy remains the principle of direct nasopharyngeal visualization. *Anterior rhinoscopy* - This technique examines the **anterior nasal cavity**, nasal septum, and inferior turbinates. - It **cannot visualize the nasopharynx** where adenoids are located due to anatomical limitations. - Useful for anterior nasal pathology but inadequate for adenoid assessment. *Manual palpation* - This is a **subjective, not objective** method that relies on examiner's tactile sensation. - Highly uncomfortable for children, causing gagging and distress. - Carries risks of trauma, bleeding, and infection. - Does not provide measurable or reproducible data, hence not considered an objective test. - Largely abandoned in modern practice due to these limitations. *None of the options* - Incorrect because **posterior rhinoscopy is a recognized objective clinical examination** for adenoids. - It allows direct visualization which can be documented and is superior to subjective methods like palpation. - While radiological methods (lateral neck X-ray) also provide objective data, among the examination techniques listed, posterior rhinoscopy is the correct answer.

Q: Mucoperichondrial flap in septoplasty is made on?

Septal cartilage. ***Septal cartilage*** - A mucoperichondrial flap is meticulously raised on the **septal cartilage** during septoplasty to access and correct deviations of the nasal septum. - This flap preserves the **perichondrium** and overlying mucosa, which is crucial for nutrient supply and healing of the septal cartilage. *Alar cartilage* - The alar cartilage forms the **lower lateral aspect** of the nose and is not involved in creating a mucoperichondrial flap for septal correction. - Procedures involving alar cartilage typically address **nasal tip projection** or alar rim deformities. *Maxillary spine* - The maxillary spine is a **bony prominence** at the anterior nasal floor and forms part of the underlying support for the septum. - While it can sometimes be a site of septal deviation, a mucoperichondrial flap is not primarily raised over the maxillary spine itself. *Sphenoid spine* - The sphenoid spine is a **bony projection** found on the sphenoid bone, located deep within the cranial base, posterior to the nasal cavity. - It is anatomically distant from the nasal septum and has no role in septoplasty or mucoperichondrial flap creation for septal surgical access.

Q: Trismus is commonly seen in

Quinsy. ***Quinsy*** - **Quinsy (peritonsillar abscess)** is the **most common cause of trismus** among pharyngeal infections. - Trismus occurs due to **inflammation and reflex spasm of the pterygoid muscles** adjacent to the abscess. - The severe pain and swelling in the peritonsillar region directly limit **mandibular movement**, making it difficult or impossible to open the mouth. - **Trismus is one of the cardinal clinical features** of quinsy. *Parapharyngeal abscess* - A **parapharyngeal abscess** can also cause trismus due to direct inflammation and irritation of the muscles of mastication. - However, it is **less common than quinsy** and typically presents with other prominent symptoms like **neck swelling**, lateral pharyngeal bulging, and internal carotid artery involvement risk. *Ludwig's angina* - While Ludwig's angina is a severe infection of the **submandibular and sublingual spaces**, trismus is **less common** and less pronounced compared to peritonsillar abscess. - The primary concern in Ludwig's angina is **airway obstruction** due to tongue elevation and "bull neck" swelling, not typically severe trismus. *Retropharyngeal abscess* - A **retropharyngeal abscess** is located behind the pharynx and typically manifests with **dysphagia**, **odynophagia**, **neck stiffness**, and respiratory distress. - While indirect muscle spasm can occur, **trismus is not a characteristic or common symptom** of retropharyngeal abscess, which primarily affects swallowing and neck mobility.

Q: Telephonophobia refers to -

Beating on ears. ⚠️ **CRITICAL NOTE**: This question contains a terminology error. "Telephonophobia" in medical literature refers to **fear of telephones** (a specific phobia), NOT a physical symptom involving the ears. However, based on the context of this being a NEET-2013 question with "beating on ears" as the answer, this may be: 1. A mistranslation or historical term no longer in use 2. Confusion with another medical term 3. An error in the original examination **For exam purposes, the marked answer reflects the original question**, but students should note: ***Beating on ears*** (Marked as correct per original question) - This answer suggests the question may have intended to ask about a different term or concept - In modern medical terminology, this is **NOT** the definition of telephonophobia - **Telephonophobia** = irrational fear of making or receiving telephone calls (psychiatric condition) *Beating on soles* - This refers to **bastinado**, a form of corporal punishment - Not related to any phobia terminology *Beating on palms* - A form of corporal punishment - Not a recognized medical terminology for any phobia *Pulling of hair* - This describes **trichotillomania**, a body-focused repetitive behavior - Trichotillomania involves recurrent, irresistible urges to pull out hair from the scalp, eyebrows, or other areas **Recommendation**: This question should be reviewed for medical accuracy. The term "telephonophobia" as used here does not align with standard medical terminology.
