Nasal Polyposis Management Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Nasal Polyposis Management. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Nasal Polyposis Management Indian Medical PG Question 1: A nasal surgery was carried out with the incision shown in the image. What was the procedure likely carried out?
- A. Submucosal resection (SMR)
- B. FESS (Functional Endoscopic Sinus Surgery)
- C. Open rhinoplasty (Correct Answer)
- D. Caldwell-Luc's procedure
Nasal Polyposis Management Explanation: ***Open rhinoplasty***
- The image displays a **transcolumellar incision** (typically inverted V or W-shaped), which is the hallmark approach for **open rhinoplasty**.
- This incision allows for direct visualization of the underlying nasal cartilages and bones, enabling precise reshaping of the nose.
*Submucosal resection (SMR)*
- SMR is a procedure to correct a **deviated nasal septum** by removing cartilage or bone from beneath the mucoperichondrial flaps.
- It involves an **intranasal incision**, usually along the septal mucosa, not an external transcolumellar incision.
*FESS (Functional Endoscopic Sinus Surgery)*
- FESS is a minimally invasive procedure used to treat **chronic sinusitis** and other sinus conditions.
- It is performed entirely **endoscopically through the nostrils**, with no external incisions on the nasal columella.
*Caldwell-Luc's procedure*
- This procedure accesses the **maxillary sinus** through an incision in the upper gum beneath the lip.
- It is used for drainage of the maxillary sinus or removal of foreign bodies/tumors, and does not involve an external nasal incision.
Nasal Polyposis Management Indian Medical PG Question 2: Which of the following statements about nasal polyps is the MOST accurate?
- A. They are usually benign. (Correct Answer)
- B. They are more common in adults than children.
- C. They are commonly associated with aspirin sensitivity.
- D. They are a complication of chronic sinusitis.
Nasal Polyposis Management Explanation: ***They are usually benign.***
- The vast majority of **nasal polyps** are benign inflammatory lesions, originating from the nasal or sinus mucosa.
- They are not considered neoplastic, differentiating them from malignant tumors that can occur in the nasal cavity.
*They are more common in adults than children.*
- While nasal polyps can occur in children, especially in association with **cystic fibrosis** or primary ciliary dyskinesia, they are still significantly more prevalent in adults.
- The peak incidence is typically in individuals between 40 and 60 years old.
*They are commonly associated with aspirin sensitivity.*
- **Aspirin-exacerbated respiratory disease (AERD)**, also known as Samter's triad, is a specific syndrome characterized by asthma, recurrent nasal polyps, and aspirin sensitivity.
- However, not all patients with nasal polyps have aspirin sensitivity; it's a specific subset of patients.
*They are a complication of chronic sinusitis.*
- While **chronic rhinosinusitis with nasal polyps (CRSwNP)** is a common presentation, and polyps often develop in the context of chronic inflammation, they are not strictly a "complication."
- Rather, nasal polyp formation is a manifestation or an end-stage of a specific inflammatory process within chronic rhinosinusitis, not merely an incidental side effect.
Nasal Polyposis Management Indian Medical PG Question 3: A patient comes with a history of asthma and sinusitis. On looking into his medical records, you notice this has been attributed to Samter’s triad. Which drug should be avoided in this patient due to its potential to exacerbate respiratory symptoms?
- A. Cotrimoxazole
- B. Co-amoxiclav
- C. Chloramphenicol
- D. Aspirin (Correct Answer)
Nasal Polyposis Management Explanation: ***Aspirin (Correct Answer)***
- Samter's triad, or **aspirin-exacerbated respiratory disease (AERD)**, is characterized by **asthma**, **nasal polyps with chronic rhinosinusitis**, and a severe reaction to **aspirin** and other **NSAIDs**.
- **Aspirin** inhibits COX-1, leading to an overproduction of **leukotrienes**, which causes bronchoconstriction and exacerbates respiratory symptoms in susceptible individuals.
- This is the drug that **must be avoided** in patients with Samter's triad.
*Cotrimoxazole (Incorrect)*
- **Cotrimoxazole** (trimethoprim-sulfamethoxazole) is an antibiotic not directly involved in the cyclooxygenase pathway.
- While allergic reactions can occur, it is **not specifically contraindicated** in Samter's triad.
*Co-amoxiclav (Incorrect)*
- **Co-amoxiclav** (amoxicillin/clavulanic acid) is a penicillin-class antibiotic, and its mechanism of action does not involve prostaglandin synthesis.
- It does not pose a specific risk for exacerbating respiratory symptoms in patients with **Samter's triad**.
*Chloramphenicol (Incorrect)*
- **Chloramphenicol** is an antibiotic that inhibits bacterial protein synthesis and is not associated with the pathogenesis of Samter's triad.
- It does not impact the **cyclooxygenase or lipoxygenase pathways** that are central to AERD.
Nasal Polyposis Management Indian Medical PG Question 4: Bernoulli's theorem explains -
- A. Airflow turbulence in stenotic airways
- B. Vocal cord adduction during inspiration
- C. Venturi effect in oxygen delivery systems (Correct Answer)
- D. Pressure changes in pleural space
Nasal Polyposis Management Explanation: ***Venturi effect in oxygen delivery systems***
- **Bernoulli's principle** states that in a streamlined (laminar) flow of fluid, an increase in velocity results in a decrease in pressure, and vice versa.
- The **Venturi effect** is a direct application of Bernoulli's principle where oxygen flows through a narrow constriction (jet orifice), causing increased velocity and decreased pressure.
- This low-pressure zone **entrains room air**, mixing it with the oxygen to deliver a precise FiO₂ (fraction of inspired oxygen).
- Venturi masks are commonly used in clinical practice to deliver controlled oxygen concentrations (24%, 28%, 31%, 35%, 40%, 60%).
*Airflow turbulence in stenotic airways*
- Turbulence in stenotic airways is **not explained** by Bernoulli's principle.
- Bernoulli's principle applies to **laminar (streamlined) flow**, not turbulent flow.
- Turbulence occurs when the **Reynolds number** exceeds a critical threshold (~2000), which happens in narrowed airways due to increased velocity.
- The turbulent airflow causes the **audible wheeze** and stridor heard in airway obstruction.
*Vocal cord adduction during inspiration*
- Vocal cord adduction and abduction are controlled by **intrinsic laryngeal muscles** (primarily the lateral cricoarytenoid and posterior cricoarytenoid muscles).
- This is a **neuromuscular phenomenon** involving the vagus nerve (recurrent laryngeal nerve), not a fluid dynamics principle.
- While airflow affects vocal cord vibration during phonation, the muscular control is independent of Bernoulli's principle.
*Pressure changes in pleural space*
- Pleural pressure changes are determined by **respiratory muscle action** (diaphragm, intercostals) and **elastic recoil** of lungs and chest wall.
- These pressure gradients drive bulk airflow into and out of the lungs (according to **Boyle's law**: P₁V₁ = P₂V₂).
- This is not explained by Bernoulli's principle, which describes pressure-velocity relationships within a flowing fluid.
Nasal Polyposis Management Indian Medical PG Question 5: Which of the following is not a feature of ethmoidal polyp?
- A. Common in adults
- B. Commonly bilateral
- C. Associated with chronic rhinosinusitis
- D. Commonly found as a single polyp (Correct Answer)
Nasal Polyposis Management Explanation: ***Commonly found as a single polyp***
- **Ethmoidal polyps** are typically **multiple** and bilateral, originating from the ethmoid sinuses.
- They rarely present as a single, isolated polyp, which is more characteristic of antrochoanal polyps.
- This is the key distinguishing feature that makes this statement INCORRECT.
*Common in adults*
- **Ethmoidal polyps** are indeed **more prevalent in adults** than in children.
- Peak incidence occurs between 30-50 years of age.
- Their incidence tends to increase with age, often associated with chronic rhinosinusitis.
*Commonly bilateral*
- **Ethmoidal polyps** almost invariably present as **bilateral polyps**, involving both sides of the nasal cavity.
- This bilateral nature is a key differentiating feature from antrochoanal polyps, which are typically unilateral.
- Bilateral presentation is one of the hallmark characteristics of ethmoidal polyps.
*Associated with chronic rhinosinusitis*
- **Ethmoidal polyps** are strongly associated with **chronic rhinosinusitis with nasal polyposis (CRSwNP)**.
- They arise from chronic mucosal inflammation of the ethmoid sinuses.
- Often associated with conditions like aspirin-exacerbated respiratory disease (AERD/Samter's triad) and non-allergic eosinophilic inflammation.
Nasal Polyposis Management Indian Medical PG Question 6: Aspirin triad is?
- A. Samter's syndrome (Correct Answer)
- B. Kartagener s syndrome
- C. Young syndrome
- D. Churg-Strauss syndrome
Nasal Polyposis Management Explanation: ***Samter's syndrome***
- Also known as **aspirin-exacerbated respiratory disease (AERD)** or aspirin triad, this condition is characterized by **asthma**, **nasal polyps**, and a sensitivity to **aspirin** and other NSAIDs [1].
- The symptoms are typically triggered by NSAID ingestion, leading to a severe asthmatic response and rhinosinusitis [1].
*Kartagener's syndrome*
- This is a subgroup of **primary ciliary dyskinesia** characterized by the triad of **situs inversus** (organ reversal), chronic sinusitis, and bronchiectasis.
- It is a genetic disorder affecting ciliary function, which is unrelated to aspirin sensitivity.
*Young syndrome*
- This syndrome is characterized by the triad of **bronchiectasis**, rhinosinusitis, and **obstructive azoospermia** in men due to ciliary dysfunction.
- It does not involve aspirin sensitivity or nasal polyps as primary features.
*Churg-Strauss syndrome*
- Now known as **Eosinophilic Granulomatosis with Polyangiitis (EGPA)**, it is a rare autoimmune disease characterized by **asthma**, **eosinophilia**, and **vasculitis**.
- While asthma is a feature, the core triad of EGPA involves systemic vasculitis and high eosinophil counts, not nasal polyps or specific aspirin sensitivity.
Nasal Polyposis Management Indian Medical PG Question 7: A woman visits the ENT outpatient department with complaints of nasal obstruction. On examination, greenish-black crusts were found in the nasal cavity covering the turbinates and septum, and she also had complete anosmia (lack of sense of smell). What other sign is most likely to be found on examination in this case?
- A. Hypertrophied inferior turbinate
- B. Polyp
- C. Foreign Body
- D. Roomy nasal cavity (Correct Answer)
Nasal Polyposis Management Explanation: ***Roomy nasal cavity***
- The presence of **greenish-black crusts**, **anosmia**, and **nasal obstruction** in the context of chronic atrophy of the nasal mucosa strongly suggests **atrophic rhinitis**.
- **Atrophic rhinitis** (also known as ozena) is characterized by progressive atrophy of the nasal mucosa, turbinates, and underlying bone, leading to an abnormally **wide and roomy nasal cavity**.
*Hypertrophied inferior turbinate*
- **Hypertrophied turbinates** typically result in nasal obstruction but would present with a narrow, rather than a roomy, nasal cavity.
- There would also be no greenish-black crusts or complete anosmia with simple turbinate hypertrophy.
*Polyp*
- **Nasal polyps** are typically pale, glistening, grape-like masses that cause nasal obstruction and hyposmia but do not cause greenish-black crusts or a roomy nasal cavity.
- They usually result from chronic inflammation and are often associated with conditions like allergic rhinitis or asthma.
*Foreign Body*
- A **nasal foreign body** would cause unilateral nasal obstruction and often a foul-smelling, purulent discharge, but not typically greenish-black crusts or a roomy nasal cavity.
- It would also not explain the complete anosmia unless it severely obstructed both nasal passages for an extended period, which is less likely than atrophic rhinitis.
Nasal Polyposis Management Indian Medical PG Question 8: A young boy came to OPD with complaints of difficulty in breathing. On examination, bilateral polyps were found. On aspiration, bleeding was seen. What will be the initial management?
- A. Septoplasty
- B. I and D
- C. Topical corticosteroids (Correct Answer)
- D. Antihistaminic
Nasal Polyposis Management Explanation: ***Topical corticosteroids***
- **Topical corticosteroids** are the **first-line medical management** for **nasal polyps**, helping to reduce inflammation and shrink polyp size.
- They work by reducing local inflammation and edema, improving nasal airway patency and breathing.
- **Important note**: The presence of **bleeding on aspiration** suggests a **vascular lesion** (such as juvenile nasopharyngeal angiofibroma in young males), which would require **imaging (CT/MRI) before any intervention** and **no biopsy** due to hemorrhage risk. However, if these are inflammatory polyps, topical steroids remain the initial medical management.
*Antihistaminic*
- **Antihistamines** are not first-line treatment for nasal polyps, as polyps are primarily an **eosinophilic inflammatory condition** rather than a simple IgE-mediated allergic reaction.
- While antihistamines may help with associated allergic rhinitis symptoms, they do **not shrink polyps** or address the underlying inflammatory pathology.
*Septoplasty*
- **Septoplasty** is a surgical procedure to correct a **deviated nasal septum**, not for treating nasal polyps.
- This would not address the bilateral polyps causing difficulty in breathing.
*I and D*
- **Incision and drainage (I&D)** is performed for abscesses or pus collections, which is not the presentation here.
- Nasal polyps are benign inflammatory masses, not infectious collections requiring drainage.
Nasal Polyposis Management Indian Medical PG Question 9: Partial closure of the nose is performed in which condition?
- A. Vasomotor rhinitis
- B. Atrophic rhinitis (Correct Answer)
- C. Allergic rhinitis
- D. Occupational rhinitis
Nasal Polyposis Management Explanation: ***Atrophic rhinitis***
- **Partial closure of the nose** (Young's operation or naris plasty) is a surgical procedure used to reduce the size of the nasal passages and improve airflow in patients with atrophic rhinitis.
- This condition involves progressive **atrophy of the nasal mucosa** and turbinates, leading to dryness, crusting, paradoxical obstruction, and often a foul odor.
*Vasomotor rhinitis*
- This condition involves **non-allergic rhinitis** triggered by environmental changes, temperature shifts, or irritants, causing symptoms like sneezing, rhinorrhea, and nasal congestion.
- Management typically involves **avoidance of triggers**, nasal corticosteroids, or anticholinergic sprays, not surgical closure of the nose.
*Allergic rhinitis*
- Caused by an ** IgE-mediated immune response** to airborne allergens, leading to inflammation of the nasal mucosa, sneezing, itching, rhinorrhea, and congestion.
- Treatment focuses on **allergen avoidance**, antihistamines, and nasal corticosteroids; surgical modification of nasal passages is not indicated.
*Occupational rhinitis*
- This form of rhinitis is caused by exposure to **irritants or allergens in the workplace**, leading to nasal symptoms similar to allergic or non-allergic rhinitis.
- Management involves **identifying and avoiding the offending agent** at work, and medical treatments like nasal sprays, but not surgical narrowing of the nostrils.
Nasal Polyposis Management Indian Medical PG Question 10: What is not true about the use of intranasal steroids in nasal polyposis?
- A. Effective in all types of nasal polyps (Correct Answer)
- B. May cause nasal irritation
- C. Reduce recurrence
- D. Most effective in eosinophilically predominant polyps
Nasal Polyposis Management Explanation: ***Effective in all types of nasal polyps***
- Intranasal steroids are primarily effective in nasal polyps with an **eosinophilic inflammatory component**, which is the most common type.
- They are **not effective in all types** - efficacy is significantly reduced in polyps with **neutrophilic inflammation** or those related to conditions like **cystic fibrosis**, reflecting different underlying pathologies.
- This statement is **FALSE**, making it the correct answer to this negation question.
*May cause nasal irritation*
- **Nasal irritation**, including **burning, stinging**, or **dryness**, is a common local side effect associated with the use of intranasal steroids.
- Other local side effects can include **epistaxis** (nosebleeds) and mucosal atrophy, though less common.
- This statement is **TRUE**.
*Reduce recurrence*
- **Intranasal steroids** are crucial in **reducing the recurrence** of nasal polyps after surgical removal.
- Their anti-inflammatory action helps to **control the underlying inflammation** that contributes to polyp formation.
- This statement is **TRUE**.
*Most effective in eosinophilically predominant polyps*
- Intranasal steroids primarily target the **eosinophilic inflammatory pathway**, which is characteristic of the majority of **chronic rhinosinusitis with nasal polyps (CRSwNP)**.
- While they have **maximal efficacy** in eosinophilic polyps, they may have limited benefit in mixed inflammatory patterns.
- Their efficacy is significantly reduced in polyps that are predominantly **neutrophilic** or associated with systemic conditions like **cystic fibrosis**, as these involve different inflammatory mechanisms.
- This statement is **TRUE**.
