True regarding Bell’s Palsy:
A. Majority of cases are idiopathic
B. Accompanied by other neurological deficits
C. Symptoms gradually arise for >72hrs
D. Complete recovery is the norm but not universal
A. Majority of cases are idiopathic
Rationale: Bell’s Palsy is primarily idiopathic, and while many patients recover completely, the majority of cases do not involve other neurological deficits, and symptoms typically arise suddenly, not gradually over more than 72 hours.
Findings of chronic rhinosinusitis in nasal endoscopy, except:
A. Purulent mucus in the posterior ethmoid region
B. Edema in the middle meatus
C. Polyps in nasal cavity
D. All are correct
A. Purulent mucus in the posterior ethmoid region
Rationale: While purulent mucus, edema, and polyps can be findings in chronic rhinosinusitis, the posterior ethmoid region is not specifically noted for purulent mucus in typical cases of chronic rhinosinusitis.
True of vascular malformations EXCEPT:
A. Always present at birth
B. Have hormonal growth spurts
C. Do not have a proliferative phase
D. Have an involution phase
C. Do not have a proliferative phase
Rationale: Vascular malformations are typically present at birth and may have growth spurts influenced by hormonal changes. They do not have a proliferative phase, which is characteristic of hemangiomas.
True of congenital hemangiomas:
A. They proliferate up to 1 year of life
B. They may involute rapidly
C. Systemic steroids are usually needed
D. All are correct
D. All are correct
Rationale: Congenital hemangiomas can proliferate up to one year, may involute rapidly, and systemic steroids are sometimes used in treatment.

a. Most common in female
b. Most common in those with fairer complexions
c. Risk factors include tobacco use, immunosuppression, and UV exposure
d. Basal cell carcinoma and malignant melanoma are not uncommon
a. Most common in female
Rationale: Lip cancer is more common in males, particularly those with fair skin, and is associated with risk factors such as tobacco use, immunosuppression, and UV exposure. Basal cell carcinoma and malignant melanoma can occur in the lip.
True of carcinoma of unknown primary, except:
A. 2-5% of all head and neck cancers
B. FNA preferred over open biopsy
C. PET-scan warranted if primary not identified on PE
D. All are correct
C. PET-scan warranted if primary not identified on PE
Rationale: Carcinoma of unknown primary accounts for 2-5% of head and neck cancers, and fine-needle aspiration (FNA) is preferred over open biopsy to avoid seeding tumor cells. However, a PET scan is warranted if the primary is not identified on physical examination and other imaging.
A 50-year-old male, chronic smoker, came in with a 1 cm lesion on the lip, with discoloration and irregular border. There are no cervical lymph nodes identified in PE and imaging. Your treatment options include the following except:
a. Surgery
b. Radiation
c. Neck Dissection
d. All of the above
c. Neck Dissection

Upon physical examination, there is also a mass in the posterolateral neck biopsy of which revealed malignancy. True regarding its diagnosis EXCEPT:
A. Associated with EBV
B. Associated with HPV
C. Advanced disease may present with cranial neuropathies
D. Distant metastatic disease is present in 5%
D. Distant metastatic disease is present in 5%
Rationale: Nasopharyngeal carcinoma, which can present with the symptoms described, is associated with EBV and sometimes HPV. Advanced disease can present with cranial neuropathies. However, distant metastatic disease is more common than 5% in advanced cases, making option D incorrect.
True regarding nasopharyngeal carcinoma, except:
A. Typically well differentiated or lymphoepithelial SCC
B. Bilateral regional disease is common
C. CT scan is used to best assess soft tissue delineation
D. Recurrent tumors are treated with reirradiation
A. Typically well differentiated or lymphoepithelial SCC
Rationale: Nasopharyngeal carcinoma is often poorly differentiated or undifferentiated, and lymphoepithelial type is common. Bilateral regional disease is frequent, and CT scan is used to assess soft tissue involvement. Reirradiation is a common treatment for recurrent tumors.
Management of patient with nasopharyngeal cancer stage I:
A. Palliative
B. Surgery
C. Chemoradiation
D. Hormonal
C. Chemoradiation
Rationale: For early-stage nasopharyngeal cancer, the standard treatment is radiation therapy alone, not chemoradiation. This discrepancy suggests a review of treatment protocols is necessary. However, for higher stages, chemoradiation is appropriate.
Most common malignant salivary gland tumor:
A. Mucoepidermoid carcinoma
B. Adenoid cystic carcinoma
C. Pleomorphic adenoma
D. Adenocarcinoma
A. Mucoepidermoid carcinoma
Rationale: Mucoepidermoid carcinoma is the most common malignant tumor of the salivary glands.

Answer: Advise some conservative treatment and closely follow up patient
Answer: Advise some conservative treatment and closely follow up patient
Rationale: For a child with a mild sore throat and no alarming symptoms, conservative management with close follow-up is appropriate.
A 1-year-old boy with a 2x2 cm bluish maculopapular, soft, compressible, nonpulsatile mass present since birth and more prominent when crying:
Answer: Infantile hemangioma
Rationale: The description fits an infantile hemangioma, a common benign vascular tumor in children that often becomes more prominent with crying.
A 50-year-old female with hoarseness of voice, no tobacco use, but post-laparoscopic cholecystectomy with foreign body sensation in throat, lesion on posterior larynx:
A. Vocal Fold Nodule
B. Laryngeal granuloma
C. Vocal fold polyp
D. Fibrous mass of the vocal fold

True regarding unilateral cord paresis except:
A. Commonly iatrogenic in origin
B. Should include autoimmune serology workup
C. May present with stridor and weak cry in children
D. CT scan is the mainstay of treatment
D. CT scan is the mainstay of treatment
Rationale: Unilateral vocal cord paresis is often iatrogenic (e.g., post-surgical), may require an autoimmune serology workup if the cause is not clear, and can present with stridor and weak cry in children. CT scan is not the mainstay of treatment but is used for diagnostic purposes.
A 23-year-old patient with a pulsating mass on the right temporal area post-brawl:
a. Give antibiotics since it may be due to infection of injury he might have sustained during the brawl
b. Request imaging studies to further investigate
c. Do needle biopsy due to the possibility of malignancy
d. Observe since the mass is most likely to be a hematoma and the pulsation is the artery beneath the hematoma
b. Request imaging studies to further investigate
Rationale: A pulsating mass could indicate a vascular injury such as a pseudoaneurysm, so imaging studies are necessary to investigate further.
Indications for admission of patients undergoing tonsillectomy EXCEPT:
A. Strongly suspected OSA
B. Patients with craniofacial abnormalities
C. >3 years of age
D. O2 saturation of 80%
C. >3 years of age

Optimal surgical management of mucoepidermoid carcinoma of the parotid gland:
A. Enucleation
B. Superficial parotidectomy
C. Total parotidectomy
D. Total parotidectomy with neck dissection
D. Total parotidectomy with neck dissection
Rationale: High-grade mucoepidermoid carcinomas often require total parotidectomy with neck dissection due to their aggressive nature and potential lymph node involvement.
True of salivary gland tumors except:
A. Majority arise in the parotid
B. Adenoid cystic carcinoma has a propensity for neural invasion
C. The larger the gland, the higher the propensity for malignancy
D. Typically well-circumscribed and slow-growing masses
C. The larger the gland, the higher the propensity for malignancy

Site of salivary gland tumor with the highest risk for malignancy:
A. Minor salivary gland
B. Sublingual gland
C. Submandibular gland
D. Parotid gland
A. Minor salivary gland
Rationale: Tumors of the minor salivary glands have the highest risk of being malignant.

In a person with suspected hyperthyroidism, the single diagnostic test to request is:
A. Thyroid scan
B. TSH assay
C. Free T3
D. Free T4
E. FNAB
B. TSH assay
Rationale: TSH assay is the most sensitive initial test for diagnosing hyperthyroidism. Low TSH levels indicate hyperthyroidism.
All of the following statements concerning radioactive iodine treatment for Graves’ disease are correct, except:
A. It is a painless procedure
B. It is indicated for patients who are poor risk for surgery
C. The incidence of hypothyroidism is greater than with surgical treatment
D. The incidence of hypothyroidism is decreased by giving frequent small doses
E. Thyroid storm is a complication
D. The incidence of hypothyroidism is decreased by giving frequent small doses
Rationale: Frequent small doses of radioactive iodine do not decrease the incidence of hypothyroidism; in fact, hypothyroidism is a common outcome of this treatment.
A 30/F presents with a 2 cm anterior neck mass on the left that moves with deglutition. On PE, the mass is soft with no associated cervical lymphadenopathy. Patient has no other signs and symptoms. Appropriate management is:
A. FNAB
B. TSH determination
