**Question:** All are true about parotid fistula except

A. Parotid fistula is a communication between the parotid gland and the skin or subcutaneous tissue overlying the gland.
B. Parotid gland is a salivary gland located in the cheek, near the angle of the mandible.
C. Parotid fistula can occur due to trauma, infection, or surgery.
D. Parotid fistula is a congenital anomaly present at birth.

**Correct Answer:** .

**Core Concept:** Parotid fistula is a communication between the parotid gland and the skin or subcutaneous tissue overlying the gland. It occurs due to the disruption of the normal anatomy and function of the parotid gland, usually as a result of trauma, infection, or surgery. The parotid gland is a salivary gland located in the cheek, near the angle of the mandible.

**Why the Correct Answer is Right:** Parotid fistula is a condition that develops as a result of an abnormal connection between the parotid gland and the skin or subcutaneous tissue. Unlike a congenital anomaly (option D), parotid fistula develops secondary to external factors such as trauma, infection, or surgical intervention. The parotid gland itself is a salivary gland, and its location is in the cheek, near the angle of the mandible.

**Why Each Wrong Option is Incorrect:**

**Option A:** Parotid fistula is not a congenital anomaly, meaning it does not occur at birth, but rather develops later due to external factors (options B, C, and D).

**Option B:** Parotid gland is not the cause of parotid fistula, as the fistula develops due to external factors (options C and D).

**Option C:** While trauma, infection, or surgery can contribute to parotid fistula development, the correct answer indicates that parotid fistula is not exclusively caused by these factors (option D). In fact, parotid fistula can also develop due to anatomical variations, scarring, or inflammation, even without external causes.

**Option D:** Parotid fistula is not a congenital anomaly, meaning it does not occur at birth, but rather develops due to external factors (options A, B, and C).

**Why Each Wrong Option is Incorrect:**

**Option A:** Parotid fistula is not a congenital anomaly, meaning it does not occur at birth, but rather develops due to external factors (options B, C, and D).

**Option B:** Parotid gland is not the cause of parotid fistula, as the fistula develops due to external factors (options C and D). The parotid gland itself plays a role in saliva production and flow, but is not the direct cause of parotid fistula.

**Option C:** Parotid fistula can also develop due to anatomical variations, scarring, or inflammation, even without external causes (option D). Unlike the other options, option D focuses on external factors, which do not solely explain the development of parotid
