Diseases of the Nose and Paranasal Sinuses Practice Questions

Q: Atrophic dry nasal mucosa, extensive encrustations, and a "woody" hard external nose are suggestive of?

Rhinoscleroma. ***Rhinoscleroma*** - This condition presents with **atrophic dry nasal mucosa**, extensive **encrustations**, and a characteristic "_woody_" hard external nose due to granulation tissue and fibrosis called **scleroma**. - It is a chronic granulomatous infection caused by **_Klebsiella rhinoscleromatis_**, leading to progressive tissue destruction and deformity. *Rhinosporidiosis* - Characterized by **polypoid lesions, friable masses**, and **strawberry-like appearance** in the nasal cavity, often associated with bleeding. - This is caused by **_Rhinosporidium seeberi_**, a pathogen found in stagnant water, and does not typically cause a woody hard external nose. *Atrophic rhinitis* - Involves progressive **atrophy of the nasal mucosa** and turbinates, leading to dryness, crusting, and a foul odor (**foetor**). - While it causes dry mucosa and encrustations, it does not typically lead to the **woody hardness** of the external nose described. *Carcinoma of the nose* - Can present with varied symptoms, including **nasal obstruction, discharge, epistaxis**, and sometimes **local invasion** leading to external deformity. - However, the combination of **atrophic mucosa, extensive crusting**, and specifically the "**woody**" hardness points more directly to Rhinoscleroma due to its characteristic fibrous tissue reaction.

Q: Strawberry appearance is seen in?

Rhinosporidiosis. ***Rhinosporidiosis*** - This is a chronic granulomatous disease caused by *Rhinosporidium seeberi* characterized by polypoid masses with a **strawberry-like (mulberry) appearance** due to numerous **sporangia** containing **spores** that are visible on the surface. - The appearance is described as \"strawberry\" or \"mulberry\" because of the granular, reddish, friable appearance of the lesions, typically seen in the nose or nasopharynx, which contain visible sporangia. - This characteristic appearance is pathognomonic and helps distinguish rhinosporidiosis from other nasal masses. *Lupus vulgaris* - This is a chronic, progressive, and destructive form of **cutaneous tuberculosis** that typically presents as reddish-brown plaques with an \"apple-jelly\" color on diascopy. - It does not present with a \"strawberry appearance\" but rather with **nodules** and **ulcerations** that can damage underlying tissue, leading to disfigurement. *Rhinoscleroma* - This is a chronic, specific **granulomatous infection** of the upper respiratory tract caused by **Klebsiella rhinoscleromatis**, presenting initially as hard, non-tender nodules or masses. - The lesions are typically firm and nodular, without the characteristic friable, red, and granular appearance of a \"strawberry.\" *Angiofibroma* - This is a **benign vascular tumor** that occurs almost exclusively in adolescent males, primarily in the nasopharynx. - It presents as a firm, lobulated mass that can cause epistaxis, but it does not have the \"strawberry appearance\" associated with fungal sporulation.

Q: Atrophy of the nasal mucosa, with extensive encrustations and a woody hard external nose, is seen in which of the following conditions?

Atrophic Rhinitis (Ozena). **Atrophic Rhinitis (Ozena)** - **Atrophy of nasal mucosa**, extensive **encrustations**, and a **woody hard external nose** are hallmark features of Ozena, a severe form of atrophic rhinitis. - This condition is characterized by chronic inflammation leading to mucosal degeneration, dilation of capillaries, and malodorous discharge. *Allergic rhinitis with nasal polyps* - **Allergic Rhinitis** primarily involves allergic inflammation, leading to sneezing, rhinorrhea, and nasal congestion, without significant mucosal atrophy or a woody external nose. - **Nasal polyps** are benign growths, commonly associated with chronic inflammation, but they do not cause the described atrophy or encrustations. *Chronic sinusitis with mucosal thickening* - **Chronic sinusitis** is characterized by persistent inflammation of the paranasal sinuses, often leading to mucosal thickening, but not atrophy or a woody hard external nose. - While it can cause nasal discharge and crusting, the extensive atrophy and the pathognomonic external nasal changes described are not typical. *Nasal septal perforation with crusting* - **Nasal septal perforation** is a hole in the nasal septum, which can cause crusting, bleeding, and whistling noises. - However, it does not typically lead to generalized mucosal atrophy of the entire nasal cavity or a "woody hard" external nose.

Q: A 30-year-old man presents with a 6-month history of nasal discharge, facial pain, and fever. On antibiotic therapy, the fever subsides. After 1 month, he again experiences symptoms of mucopurulent discharge from the middle meatus, and the mucosa of the meatus appears congested and oedematous. The next best investigation would be:

Non-Contrast CT of the nose and para-nasal sinuses. ***Non-Contrast CT of the nose and para-nasal sinuses*** - A **non-contrast CT scan** is the **gold standard** for diagnosing chronic rhinosinusitis due to its excellent anatomical detail of bony structures and paranasal sinuses. - It helps in identifying **mucosal thickening**, **obstruction**, and **bony remodelling** indicative of chronic inflammation, guiding further management and potential surgical planning. *MRI of the sinuses* - While MRI provides superior soft tissue resolution, it is **less effective than CT** in visualizing bony anatomy and subtle calcifications or bone thickness changes in the sinuses. - It is often reserved for suspected **intracranial extension**, **orbital complications**, or differentiating between inflammatory processes and tumors, which are not the primary concern here. *Plain x-ray of the para-nasal sinuses* - Plain X-rays have **limited sensitivity and specificity** for diagnosing chronic rhinosinusitis due to superimposed structures and poor resolution. - They can show gross opacification but **cannot adequately delineate** detailed sinus anatomy or the extent of mucosal disease. *Inferior meatus puncture* - Inferior meatus puncture is an **invasive procedure** primarily used for **sinus aspiration** or **lavage** in cases of acute purulent sinusitis for diagnostic culture and therapeutic drainage. - It is **not a primary diagnostic imaging tool** for evaluating chronic sinus disease or anatomical variations.

Q: An elderly patient with dementia is brought by family members who report concerns about self-neglect. On examination, you notice atrophic, dry nasal mucosa, extensive encrustations, and a woody, hard external nose. The family attributes these findings to poor hygiene due to cognitive decline. Which of the following is the most appropriate next step in management?

Rhinoscleroma. ***Rhinoscleroma*** - This is a chronic granulomatous disease caused by *Klebsiella rhinoscleromatis* characterized by progressive **fibrosis and sclerosis** of the respiratory tract - The description of a **"woody, hard external nose"** with extensive encrustations and atrophic changes is **pathognomonic for rhinoscleroma** - Often leads to significant nasal deformity and represents a serious chronic infection requiring systemic antibiotics - In elderly patients with cognitive decline, this condition may be misattributed to poor hygiene, delaying proper diagnosis *Nasal polyposis* - Presents with **boggy, edematous, grape-like masses** in the nasal cavity - The symptoms described (woody, hard external nose with atrophic mucosa) are **not typical for nasal polyposis** - Usually causes nasal obstruction and anosmia but does not cause hardening of the external nose *Atrophic rhinitis* - Involves progressive **atrophy of the nasal mucosa** and turbinates with **fetid odor (ozena)**, crusting, and nasal dryness - While this shares some features (atrophy, crusting), it does **not cause a woody, hard external nose** - The external nasal deformity is the key distinguishing feature pointing to rhinoscleroma *Chronic sinusitis* - Characterized by persistent inflammation of the paranasal sinuses with nasal discharge and congestion - Does **not cause atrophic, dry nasal mucosa** or a **woody, hard external nose** - Typically presents with facial pain, purulent discharge, and pressure symptoms

Q: Which of the following parts of the nasal septum is the most common site for epistaxis?

Anteroinferior part of nasal septum. ***Anteroinferior part of nasal septum*** - This region contains **Kiesselbach's plexus** (also known as Little's area), a highly vascularized area located in the anteroinferior nasal septum where four major arteries anastomose (anterior ethmoidal, sphenopalatine, greater palatine, and superior labial arteries). - Due to its **superficial location** and **rich blood supply**, Kiesselbach's plexus is the most common site for **epistaxis** (nosebleeds), accounting for approximately 90% of anterior nosebleeds. - This area is easily accessible and prone to trauma from nose picking, dry air, and minor injuries. *Anterosuperior part of nasal septum* - While part of the anterior septum, this region does not contain the dense vascular network of Kiesselbach's plexus. - It is less commonly associated with epistaxis compared to the anteroinferior region. *Posterosuperior part of nasal septum* - This area is supplied by branches of the **sphenopalatine artery** (Woodruff's plexus) and is associated with **posterior epistaxis**, which is less common but potentially more severe. - Posterior nosebleeds account for only about 10% of all epistaxis cases and typically occur in elderly patients or those with hypertension. *Posteroinferior part of nasal septum* - This region has a relatively less dense vascular supply compared to the anteroinferior or posterosuperior parts. - It is not a primary site for epistaxis and is less clinically significant for nasal bleeding.

Q: All of the following are true about antrochoanal polyp except which of the following?

Premalignant. ***Premalignant*** - **Antrochoanal polyps are benign growths** and typically do not carry any **premalignant potential**. - They are **inflammatory or edematous mucosal outgrowths**, not neoplastic lesions. - This is the **FALSE statement**, making it the correct answer to this EXCEPT question. *Typically unilateral* - **Antrochoanal polyps** almost exclusively originate from the **maxillary antrum** on one side, making them characteristically **unilateral**. - While ethmoidal nasal polyps can be bilateral, antrochoanal polyps are **distinctly unilateral**. *Arises from the maxillary antrum* - The defining characteristic of an **antrochoanal polyp** is its origin from the **mucosa of the maxillary sinus** (antrum). - It then extends through the **maxillary ostium** into the nasal cavity and often prolapses into the **nasopharynx** or **oropharynx**. *Does not cause malignancy* - **Antrochoanal polyps** are benign lesions and are **not known to undergo malignant transformation**. - Their primary clinical concerns relate to **nasal obstruction**, **mouth breathing**, and **snoring** due to their mechanical effects.

Q: In a typical nasal bone fracture from lateral trauma, the fracture line is usually

Horizontal. ***Horizontal*** - Lateral trauma to the nasal bones typically causes a **horizontal fracture line** along the nasal bridge, often involving the nasal septum. - This is due to the force being applied from the side, pushing the nasal bones inwards and leading to a fracture that runs **perpendicular to the long axis** of the nasal bones. *Oblique* - An oblique fracture line would involve a force applied at an **angle** to the nasal bones, which is less common in typical lateral trauma scenarios. - While possible, it is not the most common or typical fracture pattern for this specific mechanism of injury. *Comminuted* - A comminuted fracture involves **multiple fragments** or more severe crushing, which usually results from a higher-energy impact or a direct frontal blow, not a typical lateral trauma. - While comminution can occur with any fracture, it is not the **primary characteristic** of a typical lateral nasal bone fracture. *Vertical* - A vertical fracture line would suggest a force applied more directly from **above or below**, along the long axis of the nasal bones, which is inconsistent with lateral trauma. - Such a fracture pattern is less common in isolated nasal bone injuries and rare following a lateral impact.

Q: Atrophic dry nasal mucosa, extensive encrustations, and a woody hard external nose are suggestive of:

Atrophic rhinitis. ***Atrophic rhinitis*** - **Atrophic dry nasal mucosa**, extensive **encrustations**, and a **woody hard external nose** are classic presentations of atrophic rhinitis, especially the primary form (ozena). - This condition involves progressive atrophy of the nasal mucosa and turbinates. *Nasal obstruction due to foreign body* - A **foreign body** in the nose typically causes unilateral foul-smelling discharge, obstruction, and sometimes pain, not generalized dryness or extensive encrustations. - It does not lead to a "woody hard" external nose. *Chronic rhinosinusitis* - Characterized by **mucopurulent discharge**, facial pain/pressure, and nasal obstruction, usually without the extreme dryness or global mucosal atrophy seen in the question. - Encrustations can occur, but typically not to the extent or with the atrophic changes described. *Nasal polyps* - **Nasal polyps** cause nasal obstruction, anosmia (loss of smell), and often runny nose, but they do not typically cause atrophic mucosa or a woody hard external nose. - They are soft, movable growths, distinct from the features presented.

Q: Most common presentation of adult rhinosporidiosis is?

Polypoidal mass. ***Polypoidal mass*** - The most common presentation of adult rhinosporidiosis is a **friable, reddish, polypoidal or sessile mass** in the nasal cavity. - These masses are often described as having a **strawberry-like appearance** due to multiple white dots, which are sporangia. *Halitosis* - While rhinosporidiosis can cause symptoms like **nasal obstruction** and discharge, **fetid breath (halitosis)** is not typically the primary or most common presentation. - Halitosis is more commonly associated with other dental or systemic issues, or with severe secondary infections. *Pain* - **Pain is rare** in rhinosporidiosis unless there is significant secondary infection or involvement of adjacent structures. - The lesions are generally asymptomatic until they cause mechanical obstruction or bleeding. *Anosmia* - **Anosmia (loss of smell)** can occur due to mechanical obstruction of the nasal passages by the polypoidal mass. - However, it is a **secondary symptom** resulting from the mass effect, not the most common initial or direct presentation of the disease itself.
