What does a Weber test that lateralizes to the affected ear suggest? Conductive hearing
loss.
Rationale: Blocked canal or middle ear pathology amplifies sound conduction on the affected
side.
What does a Rinne test show in conductive hearing loss? Bone conduction ≥ air conduction
(BC ≥ AC).
Rationale: In conductive loss, sound bypasses impaired air pathway.
What does a Rinne test show in sensorineural hearing loss? Air conduction > bone
conduction (AC > BC), but both diminished.
Rationale: Indicates problem with cochlea or auditory nerve.
What is otosclerosis? Abnormal bone growth in the middle ear causing conductive hearing
loss.
Rationale: Common in young adults; affects stapes movement.
What findings are consistent with Ménière's disease? Episodic vertigo, tinnitus, hearing loss,
ear fullness.
Rationale: Disorder of endolymphatic fluid in the inner ear.
What is the role of cerumen impaction in hearing loss? Causes reversible conductive hearing
loss.
Rationale: Physical blockage of external auditory canal interferes with sound conduction.
,What is the most common type of hearing loss in older adults? Presbycusis (sensorineural).
Rationale: Age-related loss, usually bilateral, affects high frequencies first.
What is the significance of a deviated nasal septum? May cause nasal obstruction or
predispose to sinusitis.
Rationale: Can impact airflow, drainage of sinuses, and surgical access.
What are blue, boggy nasal turbinates indicative of? Allergic rhinitis.
Rationale: Inflammatory response causes mucosal swelling and color change.
What is anosmia and how is it tested? Loss of smell; test CN I using identifiable odors.
Rationale: Can result from sinus disease, head trauma, or neurodegeneration.
What is leukoplakia and why is it concerning? White plaque on oral mucosa that cannot be
wiped off.
Rationale: Premalignant lesion requiring biopsy.
What are common findings in oral candidiasis? White plaques that can be scraped off,
leaving erythema.
Rationale: Fungal infection; common in immunosuppression, steroid use, or after antibiotics.
What is angular cheilitis? Inflammation at the corners of the mouth.
Rationale: Associated with Candida, vitamin deficiency, or drooling.
,What causes a midline uvula to deviate with "ah" test? CN X (vagus) dysfunction.
Rationale: Uvula deviates away from the side of lesion due to muscle weakness.
What is a torus palatinus? Benign bony growth on the hard palate.
Rationale: Common variant; no treatment unless symptomatic.
How are tonsils graded? 0 = none, 1+ = visible, 2+ = between pillars, 3+ = beyond pillars, 4+ =
midline.
Rationale: Helps assess severity of tonsillar hypertrophy; 3+ or 4+ may obstruct airway.
What is the clinical significance of anterior cervical lymphadenopathy in a sore throat?
Suggests bacterial pharyngitis (e.g., Group A Strep).
Rationale: Local immune response; posterior nodes more often viral.
What findings support a diagnosis of peritonsillar abscess? Uvular deviation, unilateral
swelling, muffled voice, trismus.
Rationale: Requires urgent evaluation and drainage due to airway risk.
What does a cherry red epiglottis indicate in a child with drooling and tripod posture?
Epiglottitis.
Rationale: Medical emergency caused by Haemophilus influenzae; rapid airway obstruction risk.
, What differentiates viral pharyngitis from streptococcal pharyngitis? Viral usually has cough,
congestion; strep lacks URI symptoms, has tonsillar exudates, fever, anterior lymphadenopathy.
Rationale: Centor criteria used to differentiate.
What is the significance of cobblestoning on posterior pharynx? Chronic allergic rhinitis or
post-nasal drip.
Rationale: Lymphoid tissue response to persistent irritation.
What are signs of oral cancer? Persistent ulcer, leukoplakia, erythroplakia, indurated mass.
Rationale: Especially in smokers/alcohol users; requires biopsy.
What causes nasal polyps and how do they present? Chronic inflammation (e.g., allergic
rhinitis, aspirin sensitivity); pale, edematous, non-tender masses.
Rationale: May cause nasal obstruction or anosmia.
What are the locations of the major sinuses and how are they assessed? Frontal (above
brows), maxillary (cheeks); palpate for tenderness, transillumination for fluid.
Rationale: Pain suggests sinusitis.
What causes black hairy tongue? Accumulation of keratin; associated with poor oral
hygiene, antibiotics, smoking.
Rationale: Benign and self-limiting.
What is the role of CN XII and how is it tested? Hypoglossal nerve; have patient stick out
tongue.
Rationale: Deviation toward the lesion if nerve impaired.
