Cholesteatoma (Atticoantral) true about -a) Scanty, malodorous dischargeb) Otalgiac) Central perforationd) Ossicular involvemente) Eustachian tube dysfunction
**Core Concept**
Cholesteatoma is a type of skin cyst located in the middle ear, often associated with chronic otitis media. It is characterized by the accumulation of keratin debris, leading to the erosion of surrounding bone and tissue.
**Why the Correct Answer is Right**
Atticoantral cholesteatoma typically presents with a scanty, malodorous discharge. This is due to the accumulation of keratin debris and the subsequent bacterial colonization, which produces a foul odor. The discharge is often accompanied by a feeling of fullness or blockage in the ear. The correct answer highlights the characteristic symptom of cholesteatoma, which is essential for its diagnosis.
**Why Each Wrong Option is Incorrect**
**Option A:** Central perforation is more commonly associated with a simple perforation of the tympanic membrane, not atticoantral cholesteatoma.
**Option B:** Otolgia (ear pain) can be a symptom of cholesteatoma, but it is not a specific characteristic of atticoantral cholesteatoma.
**Option C:** Central perforation is not typically seen in atticoantral cholesteatoma, which usually involves the attic and antrum of the middle ear.
**Option D:** Ossicular involvement can occur in cholesteatoma, but it is not a specific characteristic of atticoantral cholesteatoma.
**Option E:** Eustachian tube dysfunction is often associated with otitis media with effusion, not specifically with atticoantral cholesteatoma.
**Clinical Pearl / High-Yield Fact**
A key feature of atticoantral cholesteatoma is its propensity for bone erosion, particularly in the attic and antrum of the middle ear. This can lead to complications such as ossicular damage, facial nerve paralysis, and hearing loss.
**Correct Answer: a) Scanty, malodorous discharge**
