,Q1. A patient presents with unilateral nasal congestion, facial pressure, and purulent discharge for 10 days.
CT shows complete opacification of the maxillary sinus with no air-fluid level. Which of the following best
explains the absence of an air-fluid level despite acute symptoms?
A. The patient has chronic rhinosinusitis with nasal polyps causing complete obstruction.
B. The sinus is completely filled with mucopus, preventing air-fluid layering.
C. The patient has odontogenic sinusitis with a dental abscess eroding into the sinus.
D. The scan was performed in the prone position, altering fluid distribution.
Correct Answer: B. The sinus is completely filled with mucopus, preventing air-fluid layering.
Rationale: In acute bacterial rhinosinusitis, complete opacification of the sinus indicates that the sinus cavity is
filled with purulent material, eliminating the air-fluid interface typically seen when there is partial fluid
accumulation. Option A is less likely because nasal polyps are associated with chronic inflammation. Option C is a
specific etiology but does not explain the absence of air-fluid level. Option D is incorrect as CT positioning is
standardized.
Why Wrong:
A - Chronic rhinosinusitis with polyps would show mucosal thickening and polypoid changes, not acute
complete opacification.
C - Odontogenic sinusitis may cause opacification but does not inherently explain absence of air-fluid level.
D - CT scans are routinely performed in the supine or coronal plane; prone positioning is not standard for
sinus imaging.

and Neck Surgery, 162(2_suppl), S1-S49.
Q2. A patient with a history of recurrent acute otitis media (AOM) presents with acute onset of vertigo,
sensorineural hearing loss, and nystagmus. Tympanic membrane is intact with no effusion. Which of the
following is the most likely diagnosis?
A. Labyrinthitis
B. Ménière's disease
C. Superior semicircular canal dehiscence
D. Vestibular neuritis
Correct Answer: A. Labyrinthitis
Rationale: Labyrinthitis presents with acute vertigo, sensorineural hearing loss, and nystagmus, often following or
concurrent with AOM. The intact tympanic membrane without effusion suggests the infection has reached the inner
ear via hematogenous or meningeal routes rather than through the middle ear. Ménière's disease is episodic and
associated with aural fullness. Superior semicircular canal dehiscence causes sound- or pressure-induced vertigo.
Vestibular neuritis typically spares hearing.
Why Wrong:
B - Ménière's disease is characterized by episodic vertigo lasting 20 minutes to 12 hours, with fluctuating
hearing loss and tinnitus, not acute onset with AOM history.
C - Superior semicircular canal dehiscence presents with Tullio phenomenon and Hennebert sign, not acute
hearing loss with AOM.
D - Vestibular neuritis involves acute vertigo but hearing is preserved; sensorineural loss points to
labyrinthitis.

Q3. A patient with suspected obstructive sleep apnea (OSA) undergoes polysomnography. The
apnea-hypopnea index (AHI) is 18 events/hour, and oxygen saturation nadir is 82%. Which of the following
management strategies is most appropriate as first-line therapy?
A. Uvulopalatopharyngoplasty (UPPP)
B. Mandibular advancement device (MAD)
Page 3
, C. Positive airway pressure (PAP) therapy
D. Hypoglossal nerve stimulation
Correct Answer: C. Positive airway pressure (PAP) therapy
Rationale: According to the American Academy of Sleep Medicine guidelines, PAP therapy is the first-line treatment for
moderate to severe OSA (AHI 15). This patient has moderate OSA with significant desaturation. UPPP is a surgical option but
has variable success and is not first-line. MAD is indicated for mild to moderate OSA or as an alternative when PAP is not
tolerated. Hypoglossal nerve stimulation is reserved for moderate to severe OSA with specific anatomical criteria after PAP
failure.
Why Wrong:
A - UPPP is a surgical procedure with limited efficacy in moderate OSA and is not first-line therapy.
B - MAD is an alternative for mild to moderate OSA but PAP is more effective and is first-line for AHI 15.
D - Hypoglossal nerve stimulation is a second-line therapy for patients who cannot tolerate PAP and meet specific
criteria.

Journal of Clinical Sleep Medicine, 13(3), 479-504.
Q4. A patient presents with severe sore throat, muffled voice, trismus, and deviation of the uvula to the left.
Which of the following is the most appropriate immediate step?
A. Obtain a throat culture and start oral antibiotics
B. Arrange for urgent otolaryngology consultation for needle aspiration or incision and drainage
C. Administer intravenous dexamethasone and monitor for airway compromise
D. Perform a rapid strep test and prescribe amoxicillin if positive
Correct Answer: B. Arrange for urgent otolaryngology consultation for needle aspiration or incision and
drainage
Rationale: The presentation is classic for peritonsillar abscess (PTA), with uvular deviation away from the affected
side, trismus, and muffled voice. The immediate management is drainage, either by needle aspiration or incision
and drainage, typically by an otolaryngologist. While antibiotics and steroids are adjunctive, the abscess requires
drainage. Throat culture or rapid strep is not urgent; airway assessment is critical but the definitive step is
drainage.
Why Wrong:
A - Throat culture and oral antibiotics are insufficient for an abscess; drainage is required.
C - Steroids and monitoring are adjunctive but do not replace drainage; airway compromise must be
anticipated but drainage is the priority.
D - Rapid strep test and amoxicillin do not address the abscess; drainage is necessary.

Q5. A patient with allergic rhinitis has failed intranasal corticosteroids and antihistamines. Which of the
following biologic therapies is FDA-approved for moderate-to-severe allergic rhinitis?
A. Omalizumab
B. Dupilumab
C. Mepolizumab
D. Reslizumab
Correct Answer: A. Omalizumab
Rationale: Omalizumab (anti-IgE) is approved for moderate-to-severe allergic asthma and chronic urticaria, and
has evidence for use in allergic rhinitis, particularly in patients with elevated IgE levels. However, it is not
FDA-approved specifically for allergic rhinitis as a standalone indication. Dupilumab is approved for atopic
dermatitis, asthma, and nasal polyps. Mepolizumab and reslizumab are anti-IL-5 therapies for eosinophilic asthma.
Among these, omalizumab is the most appropriate for allergic rhinitis refractory to standard therapy.
