Head and Neck Surgery Practice Questions

Q: All of the following are congenital cysts except?

Sebaceous cyst. ### Explanation The key to answering this question lies in distinguishing between **developmental (congenital)** cysts and **acquired** cysts. **Why Sebaceous Cyst is the correct answer:** A **sebaceous cyst** (more accurately termed an epidermal inclusion cyst) is an **acquired** cyst. It occurs due to the obstruction of the opening of a sebaceous gland duct, leading to the accumulation of sebum. It is not present at birth and develops later in life due to trauma or follicular blockage. A hallmark clinical feature is the presence of a **punctum**. **Analysis of Incorrect Options:** * **External Angular Dermoid:** This is a **sequestration dermoid**, a congenital cyst formed when surface ectoderm gets trapped along the lines of embryonic fusion (specifically the frontonasal and maxillary processes). It is typically located at the lateral end of the eyebrow. * **Branchial Cyst:** This is a developmental cyst arising from the remnants of the **second branchial cleft** (most commonly). It typically appears in early adulthood but is congenital in origin, located along the anterior border of the sternocleidomastoid muscle. * **Thyroglossal Cyst:** This is a congenital cyst formed along the persistent tract of the **descending thyroid gland** (from the foramen caecum to the thyroid bed). It is characteristically midline and moves upward on protrusion of the tongue. **High-Yield Clinical Pearls for NEET-PG:** * **Dermoid Cysts:** Unlike sebaceous cysts, dermoid cysts **do not** have a punctum and are often fixed to the underlying periosteum (may show "indentation" on X-ray). * **Sebaceous Cysts:** These are common on the scalp and scrotum but are **never** found on the palms and soles (as these areas lack sebaceous glands). * **Sistrunk Operation:** The definitive surgical treatment for a Thyroglossal cyst, involving removal of the cyst, the tract, and the central part of the hyoid bone.

Q: An 18-year-old male patient presented with pain and swelling in the lower jaw. Intraoral examination revealed localized gingival bleeding in the right posterior region. On palpation, pulsations can be appreciated. Radiographs also showed lesions on the frontal bone. Which condition is present in this patient?

Vascular malformation. **Explanation:** The clinical presentation of an 18-year-old with a jaw swelling associated with **gingival bleeding** and **palpable pulsations** is a classic hallmark of a **Vascular Malformation** (specifically Arteriovenous Malformations or Hemangiomas). The presence of pulsations indicates a high-flow vascular lesion. In the jaw, these lesions can cause tooth mobility and spontaneous bleeding from the gingival sulcus. The involvement of the frontal bone suggests a multi-focal or syndromic presentation (e.g., Gorham-Stout disease or multiple cavernous hemangiomas). **Why other options are incorrect:** * **Cherubism:** Typically presents in early childhood (2–7 years) as bilateral, symmetrical painless jaw swellings. Radiographically, it shows multilocular radiolucencies ("soap-bubble" appearance). It does not present with pulsations or gingival bleeding. * **Eosinophilic Granuloma (Langerhans Cell Histiocytosis):** While it can affect the jaw and frontal bone (punched-out lesions), it typically presents with "floating-in-air" teeth due to alveolar bone loss. It is an inflammatory/neoplastic process, not a vascular one, so pulsations are absent. * **Brown Tumor:** Associated with Hyperparathyroidism. While it can cause jaw lesions, it is characterized by biochemical changes (elevated Calcium and PTH) and lacks the vascular pulsations and spontaneous gingival bleeding seen here. **High-Yield Clinical Pearls for NEET-PG:** * **Pulsatile Jaw Lesion:** Always suspect Central Hemangioma or AVM. * **Aspiration:** Mandatory before any surgical intervention in suspected vascular lesions to avoid life-threatening hemorrhage ("The Great Mimicker"). * **Radiology:** May show a "sunburst" periosteal reaction or "honeycomb" radiolucency. * **Frontal Bone Involvement:** In the context of vascular lesions, consider **Gorham-Stout Disease** (Vanishing Bone Disease), characterized by progressive osteolysis and vascular proliferation.

Q: After the parotidectomy operation, a patient presents with excessive sweating and redness over the parotid region. What is the diagnosis?

Frey’s Syndrome. ***Frey’s Syndrome***- It is a common post-parotidectomy complication resulting from **aberrant regeneration** of the severed **auriculotemporal nerve**.- The parasympathetic secretomotor fibers meant for the parotid gland mistakenly reinnervate the overlying cutaneous sweat glands and blood vessels, causing **gustatory sweating** and **flushing (redness)** in the parotid region upon chewing or eating.*Horner’s syndrome*- This syndrome results from interruption of the **cervical sympathetic trunk** and presents with the classic triad of **ptosis** (droopy eyelid), **miosis** (constricted pupil), and **anhidrosis** (lack of sweating) on the affected side of the face.- It is unrelated to the auriculotemporal nerve damage common after parotidectomy and involves *lack* of sweating, contrary to the patient's complaint of *excessive* sweating.*Bell’s Palsy*- This is an **idiopathic acute peripheral facial nerve palsy**, leading to unilateral weakness or paralysis of the muscles of facial expression (e.g., inability to close the eye or raise the eyebrow).- While the facial nerve (CN VII) is at risk during parotidectomy, Bell's Palsy itself does not account for the specific symptoms of post-operative gustatory sweating and redness.*Glossopharyngeal neuralgia*- This condition involves brief, severe episodes of stabbing pain in the throat, tonsillar area, back of the tongue, or ear due to irritation of the **glossopharyngeal nerve (CN IX)**.- It is a disorder characterized purely by pain, often triggered by **swallowing** or **talking**, and is not associated with post-operative salivary gland complication symptoms like gustatory sweating.

Q: A 32-year-old patient who is a chronic tobacco chewer presents with a whitish lesion on the gingivobuccal sulcus for 7 months. What is the next best step in the management of this condition?

Local excision and biopsy. ***Local excision and biopsy*** - The clinical presentation of a persistent white patch in a chronic tobacco user is highly suspicious for **oral leukoplakia**, which is a **premalignant** condition. A **biopsy** is mandatory to establish a definitive histological diagnosis and rule out dysplasia or **squamous cell carcinoma**. - An **excisional biopsy** for a localized lesion is both diagnostic and therapeutic, as it removes the potentially malignant tissue and allows for microscopic examination. *Avoid smoking; wait and watch* - While smoking cessation is a critical part of management, a "wait and watch" approach is inappropriate for a lesion that has persisted for 7 months due to the significant risk of underlying malignancy. - Delaying a definitive diagnosis could allow a potential early-stage cancer to progress, leading to a worse prognosis. *Steroidal injection* - Steroids are used to treat **inflammatory** or **autoimmune** oral lesions like oral lichen planus or pemphigus vulgaris, not potentially neoplastic conditions like leukoplakia. - Using steroids could mask the progression of the lesion and delay the diagnosis of a malignancy. *Sclerotherapy* - Sclerotherapy is a treatment used for **vascular lesions**, such as **hemangiomas** or venous malformations, where a sclerosing agent is injected to cause thrombosis and fibrosis. - This modality is completely inappropriate for an **epithelial** lesion like leukoplakia.

Q: A 22-year-old female patient complains of discharge from the neck along with a previous history of midline neck swelling. Image of the patient is given below. All the statements regarding this patient are true except:

It is a complication of nodular goiter. ***It is a complication of nodular goiter*** - A **thyroglossal duct cyst** is a congenital anomaly resulting from the incomplete obliteration of the thyroglossal duct, a remnant of thyroid gland development. - While it can become infected or form a fistula, it is not a complication of an acquired thyroid condition like **nodular goiter**, which is an enlargement of the thyroid gland. *This is thyroglossal fistula* - The patient's history of a **midline neck swelling** with **discharge from the neck** is highly suggestive of an infected thyroglossal duct cyst that has ruptured or been incised, forming a thyroglossal fistula. - A fistula is an **abnormal tract** connecting an internal cavity to the surface, in this case, the remnant of the thyroglossal duct to the skin. *Sistrunk's operation is the treatment of choice* - The **Sistrunk procedure** involves excising the thyroglossal duct cyst along with the central portion of the hyoid bone and the core of muscle extending to the foramen cecum at the base of the tongue. - This extensive removal is necessary due to the embryological origin and the high risk of recurrence if any part of the duct system, especially near the hyoid bone, is left behind. *This discharge site will move upwards on protrusion of tongue* - The **thyroglossal duct** travels through the hyoid bone and is embryologically connected to the tongue. - Therefore, structures within the persistent thyroglossal track, including a fistula, will move upwards with the **protrusion of the tongue**, which is a classic diagnostic sign.

Q: A patient presents with a midline neck mass that moves with swallowing. The image shows the clinical presentation (arrow indicates the mass). What is the most likely diagnosis?

Thyroglossal cyst. ***Thyroglossal cyst*** - A **midline neck mass** that moves upward with **swallowing** and **tongue protrusion** is the classic clinical presentation of a **thyroglossal cyst**. - It originates from a persistent **thyroglossal duct**, appearing anywhere between the **foramen cecum** at the base of the tongue and the **thyroid gland**. *Cold abscess* - Typically originates from **tuberculous cervical lymphadenitis** and presents as a painless, fluctuant swelling without typical inflammatory signs. - Unlike a thyroglossal cyst, it is not tethered to the hyoid bone and does not move specifically with **tongue protrusion**. *Carotid body tumor* - This is a **paraganglioma** located at the **carotid bifurcation**, presenting as a lateral neck mass, not a midline one. - It exhibits a characteristic **Fontaine sign**, where the mass is mobile laterally but **fixed vertically** due to its attachment to the carotid artery. *Branchial cyst* - Arises from remnants of the **second branchial cleft** and appears as a swelling along the **upper third of the sternocleidomastoid muscle**. - It is located in the **lateral neck**, never in the midline, and does not move with swallowing or tongue movements.

Q: A 45-year-old patient presents with a slowly progressive, painless swelling in the parotid region as shown in the image. The mass is firm, non-tender, and freely mobile. Identify the most likely diagnosis.

Pleomorphic adenoma. ***Pleomorphic adenoma*** - The clinical presentation of a **solitary, well-circumscribed, slowly growing, painless mass** in the parotid gland region with **free mobility** is highly characteristic of **pleomorphic adenoma**, the most common benign salivary gland tumor (constitutes 60-70% of parotid tumors). - It typically occurs in the 4th-5th decade, grows slowly over months to years, and is **firm but not fixed** to surrounding structures. - The image shows a **unilateral, localized swelling** in the pre-auricular region without acute inflammatory signs, consistent with this diagnosis. *Mumps* - Mumps is an **acute viral infection (paramyxovirus)** causing **bilateral, painful swelling of the parotid glands**, often accompanied by fever, malaise, and orchitis. - The image depicts a **unilateral, localized, chronic swelling** without signs of acute inflammation, unlike the acute, diffuse, tender bilateral swelling typical of mumps. - Mumps rarely presents as a solitary unilateral mass in adults. *Retro-auricular lymphadenopathy* - **Retro-auricular lymphadenopathy** presents as discrete, movable lymph nodes located **posterior to the ear**, often in response to scalp or ear infections. - The lesion shown is a **larger, more diffuse swelling located anterior to the ear** in the parotid region, inconsistent with isolated lymph node enlargement. - Lymph nodes are typically smaller, multiple, and more mobile than the mass shown. *Sialadenitis* - **Acute sialadenitis** is an **inflammatory/infectious condition** of salivary glands presenting with **acute onset pain, tenderness, erythema, warmth**, and sometimes purulent discharge from the duct. - The lesion appears as a **chronic, painless, solid mass** lacking acute inflammatory signs (significant erythema, warmth, tenderness, purulent discharge). - Chronic sialadenitis would show recurrent episodes of painful swelling, which is not suggested by the clinical presentation.

Q: A 35-year-old HIV+ patient presents with the following lesion in the neck. What is correct about the management?

Gravity drainage + ATT. ***Gravity drainage + ATT*** - The image shows a **scrofula**, presenting as an abscess in the cervical lymph nodes, likely due to **tuberculous lymphadenitis**. In such cases, **gravity drainage** is crucial to evacuate the purulent material effectively, especially in the neck region. - **Anti-tubercular therapy (ATT)** is the mainstay for treating tuberculosis, and it must be initiated in combination with drainage to eradicate the infection. *ATT for another 6 months* - While ATT is essential, it is **insufficient as a standalone treatment** for a mature draining abscess like the one depicted. - Simply continuing ATT without addressing the localized collection of pus would likely result in delayed healing and potential complications. *Anti-gravity drainage + ATT* - **Anti-gravity drainage** is generally not feasible or effective for abscesses in the neck, as gravity aids in the natural flow of exudates. - This approach would go against the principles of surgical drainage for fluid collections. *Incision and drainage* - While **incision and drainage (I&D)** is a standard procedure for many abscesses, caution is exercised in tuberculous lymphadenitis (scrofula) due to the risk of creating a **continuous fistula** or **non-healing sinus**. - **Repeat aspirations** or **gravity drainage** with concurrent ATT are preferred over formal incision and drainage to minimize scarring and fistula formation.

Q: A 40-year-old smoker presents with soreness of tongue since last 2 months. On examination, it is found that the oral hygiene is poor and there is a white plaque over the lateral border of the tongue. What is the next step in the management of this patient?

Edge biopsy of the lesion. ***Edge biopsy of the lesion*** - The patient's presentation with a **white plaque** on the lateral border of the tongue, coupled with **poor oral hygiene** and a history of **smoking**, raises high suspicion for **oral potentially malignant disorders**, including **leukoplakia** or early **squamous cell carcinoma**. - An **edge biopsy** is the most appropriate next step to obtain a definitive histological diagnosis, which is crucial for determining the correct management strategy and ruling out malignancy. - The lateral border of the tongue is a **high-risk site** for oral cancer, and any persistent lesion in a smoker warrants tissue diagnosis. *Oral antifungal treatment* - This would be indicated if the white plaque were consistent with **oral candidiasis (thrush)**, which typically presents as **scrapable** white patches with a cottage cheese-like appearance. - Given the patient's significant risk factors (smoking, 2-month duration) and the location (lateral tongue border), empirical antifungal treatment without a definitive diagnosis would inappropriately delay management if the lesion is precancerous or cancerous. *Local topical cauterization* - **Cauterization** is contraindicated for undiagnosed oral lesions, especially those suspected of having malignant potential, as it could obscure the true histology and destroy tissue needed for diagnosis. - This method is only suitable for small, confirmed benign lesions or for hemostasis, never as a diagnostic or first-line approach. *Oral vitamin C supplementation* - While **vitamin C** supports overall health and tissue repair, there is no evidence it would resolve a suspicious white plaque on the tongue, especially one with potential malignant transformation. - Delaying proper diagnostic evaluation with supplementation alone could lead to progression of a serious underlying condition such as oral cancer.
