**Core Concept**
The atticoantral variety of chronic suppurative otitis media (CSOM) is characterized by its aggressive nature, with a high risk of complications such as intracranial abscesses and cholesteatoma formation. The treatment of choice for this condition should aim to eradicate the infection, prevent further complications, and restore hearing.

**Why the Correct Answer is Right**
The atticoantral type of CSOM often involves the mastoid air cells and the middle ear, making surgical intervention necessary. The treatment of choice is a combined approach of mastoidectomy and tympanoplasty, which involves the removal of diseased mastoid air cells and the repair of the eardrum (tympanic membrane). This approach allows for the complete eradication of the infection, removal of any cholesteatoma, and restoration of hearing.

**Why Each Wrong Option is Incorrect**
* **Option A:** Antibiotics alone may not be sufficient to treat the atticoantral variety of CSOM, as the infection often involves the mastoid air cells and the middle ear, requiring surgical intervention.
* **Option B:** Corticosteroids may help reduce inflammation but do not address the underlying infection or prevent further complications.
* **Option C:** Hearing aids may be useful for patients with significant hearing loss, but they do not treat the underlying infection or prevent further complications.

**Clinical Pearl / High-Yield Fact**
In cases of atticoantral CSOM, a high index of suspicion for intracranial complications such as abscesses and meningitis is necessary, and prompt surgical intervention is often required to prevent these complications.

**Correct Answer:** C.
