True statement about malignant otitis externa is:
**Core Concept**
Malignant otitis externa, also known as necrotizing otitis externa, is a severe infection of the external auditory canal that primarily affects diabetic or immunocompromised patients. It involves the destruction of the cartilage and bone surrounding the ear canal, leading to significant morbidity and potential mortality.
**Why the Correct Answer is Right**
Malignant otitis externa typically presents with severe pain, otorrhea, and conductive hearing loss. The infection is usually caused by Pseudomonas aeruginosa, which spreads to the temporomandibular joint, the carotid sheath, and the cranial nerves, leading to serious complications. The condition requires prompt treatment with antibiotics, including intravenous ciprofloxacin and amikacin, and sometimes surgical debridement.
**Why Each Wrong Option is Incorrect**
**Option A:** This option might be incorrect because it doesn't specify the correct causative organism or the severity of the infection.
**Option B:** This option might be incorrect because it doesn't mention the typical patient population at risk, such as diabetics or immunocompromised individuals.
**Option C:** This option might be incorrect because it doesn't highlight the potential for serious complications, including cranial nerve involvement and spread to adjacent structures.
**Clinical Pearl / High-Yield Fact**
It's essential to diagnose and treat malignant otitis externa promptly to prevent serious complications and mortality. A high index of suspicion is necessary in diabetic or immunocompromised patients presenting with severe ear pain and otorrhea.
**Correct Answer: None of the above. This question lacks options to provide a correct answer.**
