An antral pseudocyst, also known as a maxillary sinus retention cyst, is a benign condition that usually does not require any treatment unless it becomes symptomatic. Since it is typically asymptomatic and does not cause any issues for the patient, the preferred approach is usually observation with no active intervention. Therefore, the correct answer is C - None.

Option A, antibiotics, are not typically indicated for antral pseudocysts as they are not infectious in nature. Option B, surgery, is not the first-line treatment for antral pseudocysts unless there are specific indications such as symptoms or complications. Option D, radiation therapy, is not a standard treatment for antral pseudocysts and is not indicated for this condition.
