**Question:** Gradenigo's syndrome is characterized by all except

A. facial palsy
B. hearing loss
C. ophthalmoplegia
D. fever

**Correct Answer:** D. fever

**Core Concept:** Gradenigo's syndrome is a rare complication of acute otitis media (AOM), characterized by three major symptoms: facial palsy (House-Brackmann grade ≥ 3), hearing loss, and ophthalmoplegia (involvement of one or more extraocular muscles).

**Why the Correct Answer is Right:** Gradenigo's syndrome is caused by the spread of infection from the middle ear to the cavernous sinus, leading to inflammation and damage to the cranial nerves VII, VIII, and III. Facial palsy (A) and hearing loss (B) are the key symptoms of the syndrome, while ophthalmoplegia (C) is a less common manifestation. Fever (D) may be present, but it is not a defining feature of the syndrome.

**Why Each Wrong Option is Incorrect:**

A. Facial palsy (House-Brackmann grade ≥ 3): This is the primary symptom and represents the involvement of cranial nerve VII.

B. Hearing loss: Gradenigo's syndrome typically presents with conductive hearing loss due to middle ear inflammation, but it may also cause sensorineural hearing loss in severe cases.

C. Ophthalmoplegia: While ophthalmoplegia may occur, it is less common than facial palsy and hearing loss.

D. Fever: Although fever can be present, it is not a defining feature of Gradenigo's syndrome. The syndrome primarily presents with the combination of facial palsy, hearing loss, and ophthalmoplegia.

**Clinical Pearl:** Gradenigo's syndrome is a diagnostic clue for acute otitis media. Prompt recognition and appropriate management can prevent complications and improve outcomes.

**Core Concept:** Gradenigo's syndrome is a clinical entity characterized by facial palsy, hearing loss, and ophthalmoplegia due to infection spreading to the cavernous sinus from the middle ear. Fever may or may not be present.
