Tumors of the Nose and Paranasal Sinuses Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Tumors of the Nose and Paranasal Sinuses. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Tumors of the Nose and Paranasal Sinuses Indian Medical PG Question 1: Most common site for nasopharyngeal carcinoma is:
- A. Posterior end of septum
- B. Fossa of Rosenmuller (Correct Answer)
- C. Lateral part of nasopharynx
- D. Posterior part of nasal cavity close to the margin of sphenopalatine foramen
Tumors of the Nose and Paranasal Sinuses Explanation: ***Fossa of Rosenmuller***
- The **fossa of Rosenmuller**, also known as the pharyngeal recess, is the most common site for the development of **nasopharyngeal carcinoma (NPC)**.
- This anatomical location is prone to tumor development due to its complex lymphatic drainage and potential exposure to environmental factors.
*Post part of Nasal cavity close to the margin of sphenopalatine foramen*
- While this area is part of the nasopharynx, it is not the **predominant site** for the origin of **nasopharyngeal carcinoma (NPC)**.
- Tumors originating here would be less common than those in the fossa of Rosenmuller.
*Post end of septum*
- The posterior end of the nasal septum is an anatomical structure in the nasopharynx but is **not a common primary site** for **nasopharyngeal carcinoma**.
- Tumors are more likely to arise from the lateral walls or roof of the nasopharynx.
*Lateral part of nasopharynx*
- The lateral part of the nasopharynx is a general description, and while the **fossa of Rosenmuller** is located on the lateral wall, it is a **more specific and common site** for NPC.
- Simply stating "lateral part" is less precise than identifying the fossa of Rosenmuller.
Tumors of the Nose and Paranasal Sinuses Indian Medical PG Question 2: A 1-year-old child was brought to the outpatient department with a soft and compressible swelling on the nose that increases on coughing. Which of the following is most likely the diagnosis?
- A. Meningoencephalocele (Correct Answer)
- B. Arteriovenous malformation
- C. Lacrimal sac cyst
- D. Ethmoid cyst
Tumors of the Nose and Paranasal Sinuses Explanation: ***Meningoencephalocele***
- A soft, compressible nasal swelling that increases with **coughing** or **straining** is highly suggestive of a meningoencephalocele due to increased intracranial pressure.
- This condition involves a **herniation of brain tissue** (encephalocele) and meninges through a bony defect, often in the nasal region.
*Lacrimal sac cyst*
- A lacrimal sac cyst would typically present as a swelling in the **medial canthal region** and is usually associated with **tear duct obstruction**, not directly on the nose increasing with coughing.
- While soft, it is not usually **compressible** or affected by changes in intracranial pressure in the same way.
*Arteriovenous malformation*
- An arteriovenous malformation (AVM) would typically present as a **pulsatile** mass with a **bruit**, and might cause warmth or discoloration.
- It would not characteristically increase in size with **coughing** as a result of intracranial pressure changes.
*Ethmoid cyst*
- An ethmoid cyst is a fluid-filled sac originating from the **ethmoid sinuses**. While it can cause nasal obstruction or swelling, it usually presents as a firm, non-pulsatile mass.
- It would not typically exhibit **compressibility** with an increase in size when coughing, differentiating it from an intracranial connection.
Tumors of the Nose and Paranasal Sinuses Indian Medical PG Question 3: Carcinoma of maxillary sinus stage III {T3 N0 M0}, Treatment of choice is
- A. Chemotherapy
- B. Chemotherapy and Surgery
- C. Radiotherapy
- D. Surgery and Radiotherapy (Correct Answer)
Tumors of the Nose and Paranasal Sinuses Explanation: ***Surgery and Radiotherapy***
- For **stage III maxillary sinus carcinoma (T3 N0 M0)**, a **multimodal approach** combining surgical resection with postoperative radiation therapy is generally considered the standard of care for optimal local control and survival outcomes.
- **Surgery** aims to achieve clear margins, while **radiotherapy** targets microscopic residual disease and reduces the risk of recurrence.
*Chemotherapy*
- **Chemotherapy** alone is typically used for **systemic disease** or as a palliative measure, not as a primary curative treatment for localized stage III carcinoma.
- Its role in **maxillary sinus cancer** is often reserved for induction therapy in advanced unresectable cases or as part of concurrent chemoradiation.
*Chemotherapy and Surgery*
- While chemotherapy may be used in combination with surgery for some advanced cancers, it is not the primary adjunctive modality alongside surgery for **stage III maxillary sinus carcinoma**; **radiotherapy** is more commonly indicated.
- The primary role of chemotherapy in this context is usually in conjunction with radiation or for distant metastasis.
*Radiotherapy*
- **Radiotherapy alone** would not be sufficient for a T3 tumor, which involves extensive local invasion (e.g., bone of orbit, anterior ethmoid sinus, pterygoid plates, or cheek skin).
- While radiation is crucial, **surgical debulking** or resection is necessary to remove the bulk of the disease and allow the radiation to be more effective.
Tumors of the Nose and Paranasal Sinuses Indian Medical PG Question 4: Most common presentation in nasopharyngeal carcinoma is with:
- A. Cervical lymphadenopathy (Correct Answer)
- B. Epistaxis
- C. Hoarseness of voice
- D. Nasal stuffiness
Tumors of the Nose and Paranasal Sinuses Explanation: ***Cervical lymphadenopathy***
- **Cervical lymphadenopathy** is the most frequent initial symptom, with over 75% of patients presenting with a palpable neck mass, often a **painless, firm mass** in the upper deep cervical chain.
- This is due to the rich lymphatic drainage of the nasopharynx to the cervical lymph nodes, leading to early metastasis.
*Epistaxis*
- While **epistaxis** (nosebleeds) can occur in nasopharyngeal carcinoma, it is generally not the most common presenting symptom.
- It usually presents as recurrent, mild **epistaxis** or bloody discharge rather than severe bleeding.
*Hoarseness of voice*
- **Hoarseness of voice** is typically associated with laryngeal involvement or recurrent laryngeal nerve palsy, which is a less common and usually later manifestation of nasopharyngeal carcinoma.
- Primary nasopharyngeal tumors do not directly cause hoarseness unless they extend significantly or metastasize to structures affecting vocal cord function.
*Nasal stuffiness*
- **Nasal stuffiness** or obstruction can be a symptom due to tumor growth within the nasopharynx.
- However, it is a less specific symptom and often overshadowed by the more prominent presentation of cervical lymphadenopathy.
Tumors of the Nose and Paranasal Sinuses Indian Medical PG Question 5: Treatment of choice for carcinoma of the maxillary sinus with T3N0M0?
- A. Surgery
- B. Radiotherapy
- C. Surgery and Radiotherapy (Correct Answer)
- D. Surgery and chemotherapy
Tumors of the Nose and Paranasal Sinuses Explanation: ***Surgery and Radiotherapy***
- For **T3N0M0 maxillary sinus carcinoma**, a multidisciplinary approach involving both **surgery** (for primary tumor resection) and **postoperative adjuvant radiotherapy** is the preferred treatment.
- This combined modality offers the best chance for **local control** and improved survival due to the aggressive nature and potential for microscopic residual disease in T3 tumors.
*Surgery*
- While surgery is crucial for removing the primary tumor, it alone may not be sufficient for **T3 tumors** due to the high risk of **microscopic residual disease** at the margins.
- **Single modality treatment** with surgery for T3 tumors often results in higher rates of **local recurrence**.
*Radiotherapy*
- **Radiotherapy alone** is generally reserved for unresectable tumors or in cases where surgery is contraindicated due to comorbidities.
- It may not achieve adequate **tumor eradication** as a primary standalone treatment for a T3 tumor without the benefit of surgical debulking.
*Surgery and chemotherapy*
- **Chemotherapy** is often considered in the context of **neoadjuvant** or **concurrent chemoradiation** for advanced head and neck cancers, or for metastatic disease.
- For localized T3N0M0 maxillary sinus carcinoma, the primary adjuvant modality after surgery is **radiotherapy**, with chemotherapy reserved for specific scenarios or advanced stages.
Tumors of the Nose and Paranasal Sinuses Indian Medical PG Question 6: Treatment of resectable T4N0M0 stage of head and neck carcinoma is?
- A. Radiotherapy alone
- B. Surgery and Radiotherapy (Correct Answer)
- C. Chemoradiation
- D. Surgery alone
Tumors of the Nose and Paranasal Sinuses Explanation: ***Surgery and Radiotherapy***
- For **resectable T4N0M0 head and neck carcinoma**, the standard treatment is **surgical resection** of the primary tumor followed by **adjuvant radiotherapy**.
- This approach achieves optimal **local control** for advanced primary tumors without nodal involvement.
- **Adjuvant radiotherapy** is essential for T4 tumors due to high risk of microscopic residual disease and local recurrence.
- Surgery allows for complete tumor removal with negative margins, while radiotherapy addresses subclinical disease.
*Radiotherapy alone*
- Radiotherapy alone is **insufficient as monotherapy** for T4 tumors due to the large tumor burden and extensive local invasion.
- Single modality radiation cannot reliably achieve adequate tumor control for advanced primary lesions.
- Generally reserved for early-stage disease or patients unfit for surgery.
*Chemoradiation*
- **Definitive chemoradiation** is an alternative for **unresectable T4 tumors** or when organ preservation is desired (e.g., laryngeal cancer).
- For **resectable** T4N0M0 disease, surgery with adjuvant RT is preferred as it provides better local control and allows pathological staging.
- Chemoradiation may be used postoperatively if high-risk features are found (positive margins, perineural invasion, extranodal extension).
- In this **N0 case with resectable tumor**, upfront surgery is the preferred initial approach.
*Surgery alone*
- While surgical resection is crucial for T4 tumors, **surgery alone is inadequate** due to high risk of locoregional recurrence.
- T4 classification indicates extensive local invasion, necessitating **adjuvant radiotherapy** to eradicate microscopic disease.
- Combined modality treatment (surgery + RT) significantly improves local control and survival compared to surgery alone.
Tumors of the Nose and Paranasal Sinuses Indian Medical PG Question 7: Most common malignancy of maxillary antrum:
- A. Muco-epidermoid Carcinoma
- B. Adenoid cystic Carcinoma
- C. Adenocarcinoma
- D. Squamous cell Carcinoma (Correct Answer)
Tumors of the Nose and Paranasal Sinuses Explanation: ***Squamous cell Carcinoma***
- **Squamous cell carcinoma (SCC)** accounts for approximately **80% of all malignant tumors** of the maxillary antrum.
- This prevalence is due to the **squamous metaplasia** of the respiratory epithelium lining the sinus, especially in response to chronic irritation or inflammation.
*Mucoepidermoid Carcinoma*
- While it can occur in the maxillary sinus, **mucoepidermoid carcinoma** is a rare tumor, typically arising from **minor salivary glands**.
- It is far **less common** than squamous cell carcinoma in the maxillary antrum.
*Adenoid cystic Carcinoma*
- **Adenoid cystic carcinoma** is a relatively rare tumor that more commonly affects the **major and minor salivary glands** and is known for its **perineural invasion** and slow growth, but it is not the most common in the maxillary antrum.
- Its presence in the maxillary sinus is usually an **extension from adjacent structures** or a primary tumor of minor salivary glands within the sinus.
*Adenocarcinoma*
- **Adenocarcinoma** of the maxillary antrum is less common than SCC, often associated with exposure to **wood dust** or **leather processing**.
- It typically arises from **seromucinous glands** within the sinus lining, but its incidence is significantly lower than that of squamous cell carcinoma.
Tumors of the Nose and Paranasal Sinuses Indian Medical PG Question 8: A 35-year-old female patient presents with complaints of nasal obstruction and post-nasal drip. There is a past history of FESS for failed conservative management 5 years ago.
Uncinectomy and maxillary ostium dilation was done during the previous FESS. A DNE done now shows patent ostia and mucosal edema of the maxillary sinus lining. What is the next best step in management?
FESS - Functional endoscopic sinus surgery
- A. Tissue biopsy for histopathological examination (Correct Answer)
- B. Immediate revision FESS
- C. High-dose systemic steroids
- D. Topical antifungal therapy
Tumors of the Nose and Paranasal Sinuses Explanation: ***Tissue biopsy for histopathological examination***
- The patient has persistent **mucosal edema** despite previous FESS and patent ostia, raising suspicion for less common etiologies such as **eosinophilic mucin rhinosinusitis** or even a **neoplastic process**, which require histological confirmation.
- A biopsy is essential to differentiate between inflammatory conditions not responsive to standard medical therapy and other distinct pathologies, guiding further specific treatment.
*Immediate revision FESS*
- Revision FESS is usually considered when there is evidence of **recurrent obstruction** or **sinus scarring**, neither of which is indicated by the "patent ostia" observed during DNE.
- Performing FESS without addressing the underlying cause of persistent mucosal edema is unlikely to be curative and risks repeat failure.
*High-dose systemic steroids*
- While systemic steroids can reduce inflammation, persistent symptoms despite prior surgical intervention and observed mucosal edema warrant investigating the underlying cause before resorting to high-dose systemic therapy.
- Prolonged use of high-dose systemic steroids carries significant side effects and should be reserved for cases where the etiology is well-defined and responsive, such as severe asthma or certain inflammatory conditions.
*Topical antifungal therapy*
- While fungal elements can contribute to rhinosinusitis, the broad application of topical antifungals without specific evidence of fungal infection (e.g., fungal balls, invasive fungal sinusitis) is not standard initial management.
- The description of "mucosal edema" and absence of specific fungal features (like thick, inspissated mucin or fungal hyphae) makes empirical antifungal therapy less appropriate as the primary next step.
Tumors of the Nose and Paranasal Sinuses Indian Medical PG Question 9: The following test is done for the evaluation of:
- A. Cheek tenderness in maxillary sinusitis (Correct Answer)
- B. Abnormality of nasal valve
- C. Severity of proptosis
- D. Skin pinch for dehydration
Tumors of the Nose and Paranasal Sinuses Explanation: ***Cheek tenderness in maxillary sinusitis***
- The image shows a person palpating the area over the **maxillary sinus** with their fingers. This examination technique is used to elicit tenderness, a common sign of **maxillary sinusitis**.
- **Tenderness on palpation** over the maxillary sinus is a key clinical finding indicating inflammation or infection within the sinus cavity.
*Abnormality of nasal valve*
- Evaluation of the nasal valve typically involves external observation, internal examination with a speculum, or specialized maneuvers like the **Cottle test**, which involves pulling the cheek laterally to open the valve; it does not involve pressing on the cheek as depicted.
- The nasal valve is an internal structure, and its palpation for abnormality would not be performed by pressing on the outer cheekbone as shown.
*Severity of proptosis*
- Proptosis (exophthalmos) refers to the **abnormal protrusion of the eyeball**. It is typically measured using an **exophthalmometer**.
- The action shown in the image, pressing on the cheek, is not a method used to assess or quantify the severity of proptosis.
*Skin pinch for dehydration*
- The **skin pinch test** (turgor test) for dehydration is usually performed by pinching the skin on the back of the hand, lower arm, or abdomen, not the cheek.
- Delayed return of the pinched skin to its normal state, known as **poor skin turgor**, indicates dehydration. The image does not show this technique.
Tumors of the Nose and Paranasal Sinuses Indian Medical PG Question 10: What is the treatment of choice for ethmoidal polyps?
- A. Functional Endoscopic sinus surgery with polypectomy (Correct Answer)
- B. Intranasal ethmoidectomy
- C. Transantral ethmoidectomy
- D. Extranasal ethmoidectomy
Tumors of the Nose and Paranasal Sinuses Explanation: ***Functional Endoscopic sinus surgery with polypectomy***
- This is the **gold standard treatment** for ethmoidal polyps, as it allows for **direct visualization** and complete removal of polyps while preserving healthy mucosa.
- It also enables restoration of normal sinus ventilation and drainage, which helps prevent recurrence.
*Intranasal ethmoidectomy*
- This is an **older technique** that is performed blindly and carries a higher risk of complications, such as **orbital or intracranial injury**, compared to endoscopic approaches.
- It often results in incomplete polyp removal, leading to a higher rate of recurrence.
*Transantral ethmoidectomy*
- This approach, also known as the **Caldwell-Luc procedure**, is primarily used for diseases of the **maxillary sinus** and is not the preferred method for isolated ethmoidal polyps.
- It is a more invasive external approach with risks including facial swelling, pain, and damage to dental nerves.
*Extranasal ethmoidectomy*
- This is a more invasive **external approach** involving an incision on the face and is generally reserved for extensive or complicated cases, such as **tumors or severe trauma**, not for routine polyp removal.
- It carries risks of visible scarring and longer recovery times, making it less favorable than endoscopic techniques.
