Question 211: A patient presented with unilateral nasal obstruction associated with watery nasal discharge and bleeding. A diagnosis of inverted papilloma is made. Which of the following is true about this condition?
- A. Malignant and invasive
- B. Benign and non-invasive
- C. Malignant and non-invasive
- D. Benign and invasive (Correct Answer)
Explanation: ***Benign and invasive*** Inverted papilloma (Schneiderian papilloma) is a **benign epithelial tumor** that characteristically exhibits **locally invasive behavior**, making option D correct. **Key features of inverted papilloma:** - **Benign histology** but behaves aggressively - **Locally invasive** - grows into underlying stroma and can erode bone - Unilateral presentation (cardinal feature) - Origin from lateral nasal wall/maxillary sinus - High recurrence rate (10-30%) if incompletely excised - **Malignant transformation risk: 5-15%** (usually to squamous cell carcinoma) - Requires complete surgical excision with wide margins **Clinical presentation (as in this case):** - Unilateral nasal obstruction (most common) - Epistaxis (bleeding) - Watery rhinorrhea - Fullness/mass sensation *Incorrect: Malignant and invasive* While inverted papilloma is invasive, it is histologically benign, not malignant. However, surveillance is needed due to malignant transformation potential. *Incorrect: Benign and non-invasive* Though benign, inverted papilloma is NOT non-invasive. Its locally aggressive behavior with invasion into adjacent structures distinguishes it from simple benign polyps. *Incorrect: Malignant and non-invasive* This option is incorrect on both counts - inverted papilloma is benign (not malignant) and invasive (not non-invasive).
Question 212: A 16-year-old boy presented with recurrent epistaxis. There is no history of trauma associated with it. On examination, there is a firm purplish mass on the left posterior choanae. Which of the following is the most appropriate for managing this patient?
- A. Surgical excision (Correct Answer)
- B. Radiotherapy
- C. FNAC
- D. Needle biopsy
Explanation: ***Surgical excision***- The presentation (adolescent male, recurrent epistaxis, purplish posterior choanal mass) is classic for **Juvenile Nasopharyngeal Angiofibroma (JNA)**, a highly vascular, benign tumor.- **Surgical excision** is the definitive treatment for JNA, which is usually preceded by preoperative **embolization** to dramatically reduce the risk of severe intraoperative hemorrhage.*Needle biopsy*- Performing any blind or needle biopsy in suspected JNA is strictly **contraindicated** due to the high risk of severe, uncontrolled hemorrhage.- Diagnosis relies primarily on **clinical features** and characteristic findings on imaging (CT/MRI), which delineate the tumor's extent and vascular supply.*FNAC*- Similar to a core or punch biopsy, **FNAC (Fine Needle Aspiration Cytology)** is contraindicated due to the tumor's characteristic lack of a capillary system and abundance of large, thin-walled vessels.- This highly vascular nature means even minimal trauma can lead to profuse and life-threatening **bleeding** which can be difficult to manage. *Radiotherapy*- **Radiotherapy** is generally reserved for large, inoperable, recurrent, or residual tumors, particularly those with significant intracranial extension.- It is considered a secondary modality and is avoided as primary treatment for localized JNA due to associated risks of long-term morbidities such as **secondary malignancies** or **pituitary dysfunction** in adolescents.
Question 213: A patient presents to the emergency department with significant nasal trauma after a fall. Examination reveals a deviated nasal pyramid and palpation confirms crepitus and mobility of the nasal bones. A lateral nasal bone X-ray confirms a displaced nasal bone fracture. Which of the following instruments is specifically designed for the closed reduction of a displaced nasal bone fracture?
- A. Luc's forceps
- B. Bayonet forceps
- C. Walsham forceps (Correct Answer)
- D. Tilley's forceps
Explanation: ***Walsham forceps*** - The **Walsham forceps** is specifically designed for the **closed reduction** of displaced nasal bone fractures, utilizing an internal blade and an external padded blade for controlled lifting and manipulation. - They allow the surgeon to gain purchase on the fractured segments to safely elevate **depressed nasal bones** and restore the nasal pyramid's shape. *Tilley's forceps* - **Tilley's nasal dressing forceps** are primarily used for general purposes, such as removing foreign bodies, packing the nose, or removing **small polyps** from the nasal cavity. - They lack the necessary structure, leverage, and specialized curve required to successfully engage and **reduce** a bony nasal fracture. *Luc's forceps* - **Luc's forceps** are generally used for applying **anterior nasal packing** or removing dressings, serving primarily as a dressing forceps. - Although used in the nose, they do not have the specialized geometry needed to grasp and elevate the bony cartilage for **fracture reduction**. *Bayonet forceps* - **Bayonet forceps** are commonly used in microscopic or endoscopic procedures (e.g., ear or fine nasal surgery) because their offset handle prevents the surgeon's hand from obstructing the line of sight. - They are used for fine grasping, packing, or dissection, but are entirely unsuitable for the heavy task of **reducing** a **displaced nasal bone fracture**.
Question 214: What test is not used for testing olfaction?
- A. Arnold stick test (Correct Answer)
- B. UPSIT
- C. CC-SIT
- D. Smell diskettes
Explanation: ***Arnold stick test*** - The **Arnold stick test** is primarily used for evaluating **hearing**, specifically for assessing **eardrum mobility** and the integrity of the **ossicular chain**. - It involves a small speculum connected to a rubber bulb, and the movement of the eardrum is observed with a microscope, making it unrelated to olfaction. *UPSIT* - The **University of Pennsylvania Smell Identification Test (UPSIT)** is a widely used and well-validated test for **olfactory function**. - It consists of 40 scratch-and-sniff odorants, and the patient identifies each odor from a set of four choices. *CC-SIT* - The **Cross-Cultural Smell Identification Test (CC-SIT)** is a shorter, 12-item version derived from the UPSIT, designed for **cross-cultural applicability** in testing olfaction. - It also uses a scratch-and-sniff method to assess the ability to identify various odors. *Smell diskettes* - **Smell diskettes**, or smell identification tests using diskettes, are various types of **odor identification kits** where different odors are impregnated onto small disks. - These are common tools used to assess **olfaction** by requiring patients to identify specific smells.
Question 215: Partial closure of the nose is performed in which condition?
- A. Vasomotor rhinitis
- B. Atrophic rhinitis (Correct Answer)
- C. Allergic rhinitis
- D. Occupational rhinitis
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.
Question 216: What is the primary surgical application of Killian's incision?
- A. Septoplasty (Correct Answer)
- B. SMR
- C. Proof puncture
- D. Modified radical mastoidectomy
Explanation: ***Septoplasty*** - Killian's incision is the **classic hemitransfixion incision** used primarily in septoplasty to lift the mucoperichondrial flap and expose the septal cartilage and bone. - This incision provides adequate access for correcting septal deviations while preserving the blood supply to the septum. - Septoplasty is the **most common modern application** of Killian's incision, as it involves conservative reshaping and repositioning of the septum. *SMR* - **Submucous resection (SMR)** also traditionally uses **Killian's incision** as its surgical approach. - However, SMR involves more extensive removal of septal cartilage and bone compared to septoplasty. - SMR has largely been **replaced by septoplasty** in modern practice due to concerns about complications like septal perforation and saddle nose deformity. - While both procedures use Killian's incision, septoplasty is now the primary and most common application. *Proof puncture* - **Proof puncture** refers to a diagnostic and therapeutic procedure used to confirm and drain maxillary sinus infections. - It involves puncturing the **inferior meatus** of the nose, which is unrelated to septal surgery or Killian's incision. *Modified radical mastoidectomy* - This procedure is performed to remove disease from the **mastoid air cells** and preserve hearing where possible. - It involves an incision behind the ear (**postauricular incision**), which is completely different from a Killian's incision used for septal surgery.
Question 217: During functional endoscopic sinus surgery the position of the patient is
- A. Lateral
- B. Lithotomy
- C. Reverse Trendelenburg (Correct Answer)
- D. Trendelenburg
Explanation: ***Reverse Trendelenburg*** - This position helps to reduce **venous congestion** in the surgical field, which is crucial for maintaining clear visibility during **functional endoscopic sinus surgery (FESS)**. - It minimizes **bleeding** by allowing gravity to drain blood away from the head and neck, improving surgical precision and safety. *Trendelenburg* - This position involves tilting the patient with the head lower than the feet, which would increase **venous pressure** in the head and neck. - Increased venous congestion would lead to significant **bleeding**, severely impairing visibility during FESS. *Lateral* - The lateral position is generally used for procedures involving the **side of the body**, such as kidney surgery or lung procedures. - It does not provide the optimal ergonomic access or venous drainage benefits required for **endoscopic sinus surgery**. *Lithotomy* - The lithotomy position is characterized by the patient lying on their back with hips and knees flexed and supported, primarily used for **pelvic or perineal procedures**. - This position is entirely inappropriate for **head and neck surgery** as it does not allow proper access to the sinus area.
Question 218: Which of the following is an indication for Functional Endoscopic Sinus Surgery (FESS)?
- A. inverted papilloma
- B. Optic nerve decompression
- C. Orbital abscess
- D. Nasal polyposis (Correct Answer)
Explanation: ***Nasal polyposis*** - **Nasal polyposis refractory to medical management** is one of the most common and primary indications for **FESS**, as it allows for direct removal of polyps and restoration of sinus drainage and ventilation. - **FESS** aims to improve ventilation and mucociliary clearance within the paranasal sinuses, addressing the underlying chronic rhinosinusitis that leads to polyp formation. *Inverted papilloma* - **Inverted papilloma** is a benign but locally aggressive **epithelial tumor** that does require surgical excision, and FESS techniques are used for its removal. - However, it often requires **extended endoscopic approaches** (such as medial maxillectomy or modified endoscopic medial maxillectomy) rather than standard FESS to ensure complete removal and prevent recurrence due to its invasive growth pattern. - In the context of this question, **nasal polyposis** is the more straightforward and common indication for standard FESS. *Orbital abscess* - An **orbital abscess** is a surgical emergency requiring prompt drainage. While endoscopic sinus surgery may be used as part of the surgical approach to drain the abscess and address contributing sinusitis, the primary goal is abscess drainage rather than the sinus disease itself. - The indication here is the orbital complication, not chronic sinus disease per se. *Optic nerve decompression* - **Endoscopic optic nerve decompression** can be performed using FESS techniques for conditions like traumatic optic neuropathy or compressive lesions. - However, this is a specialized, advanced procedure for specific optic nerve pathology, not a routine indication for FESS in the management of chronic rhinosinusitis and its direct complications.
