A 10-year-old boy presents with toicollis, a tender swelling behind the angle of mandible and fever. He had history of ear discharge for the past 6 years. Examination of the ear showed purulent discharge and granulations in the ear canal. Most probable diagnosis is:
## **Core Concept**
The question presents a case suggestive of a complication arising from chronic otitis media. The symptoms described, such as torticollis, tender swelling behind the angle of the mandible, fever, purulent discharge, and granulations in the ear canal, point towards an infection that has spread beyond the confines of the ear.
## **Why the Correct Answer is Right**
The clinical presentation is highly suggestive of **Bezold's abscess**, which is a complication of mastoiditis. Mastoiditis is an infection of the mastoid part of the temporal bone, often arising from chronic otitis media. The infection can spread from the mastoid cortex to the surrounding tissues, leading to abscess formation. The location behind the angle of the mandible and the symptoms of torticollis (due to spasm of the neck muscles) and fever are classic for this condition. The history of chronic ear discharge supports the progression from chronic otitis media to mastoiditis and subsequently to Bezold's abscess.
## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is not provided, but typically, incorrect options might include diagnoses such as a peritonsillar abscess, which presents with severe sore throat, fever, and difficulty swallowing, not matching the ear symptoms described.
- **Option B:** Similarly, another potential incorrect option could be a diagnosis like lymphadenitis, which could present with swelling and tenderness but wouldn't fully explain the torticollis, granulations in the ear canal, or the chronic ear discharge.
- **Option C:** If another option like a retropharyngeal abscess were considered, it would present with symptoms related to the neck and throat, such as difficulty swallowing and a bulge in the back of the throat, not specifically related to the ear.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that **Bezold's abscess** is a serious complication that requires prompt drainage and antibiotic therapy. Clinicians must be vigilant in recognizing complications of otitis media, especially in patients with a history of chronic ear infections. The presence of granulations in the ear canal alongside chronic discharge is highly suggestive of a complicated infection.
## **Correct Answer:** C. Bezold's abscess.
