**Core Concept**
Myiasis, a condition characterized by the infestation of living tissues by fly larvae (maggots), can occur in various parts of the body, including the nose. The treatment of myiasis depends on the extent of the infestation and the affected area.

**Why the Correct Answer is Right**
The correct approach to treating nasal myiasis involves the removal of the maggot larvae using a gentle and atraumatic technique to prevent further tissue damage. This is typically achieved through surgical excision or careful manual removal under local anesthesia. The key is to avoid applying heat or caustic agents, which can cause the maggots to burrow deeper into the tissue. This approach also minimizes the risk of complications, such as infection or scarring.

**Why Each Wrong Option is Incorrect**
**Option A:** Applying heat to the affected area is not recommended as it can cause the maggots to burrow deeper into the tissue, exacerbating the condition.
**Option B:** Using caustic agents to kill the maggots is also contraindicated, as it can lead to tissue damage and scarring.
**Option C:** Antibiotics may be used to treat secondary infections that may arise from the myiasis, but they do not address the underlying infestation.

**Clinical Pearl / High-Yield Fact**
When treating myiasis, it's essential to remember that the maggots can burrow deeper into the tissue if they sense heat or are disturbed, making gentle and atraumatic removal the preferred approach.

**Correct Answer:** C. Antibiotics may be used to treat secondary infections that may arise from the myiasis, but they do not address the underlying infestation.
