Where is the facial nerve located during a superficial parotidectomy?

• A. Inferior to the anterior belly of digastric
• B. Superior to the posterior belly of digastric
• C. At the level of the mastoid tip
• D. Below the tragal cartilage

Answer: (B)

The correct choice, which indicates that the facial nerve is located superior to the posterior belly of the digastric muscle during a superficial parotidectomy, is based on the anatomical relationship of the facial nerve within the parotid gland region. During a superficial parotidectomy, which is performed to remove a portion of the parotid gland while preserving important structures, the surgeon must be aware of the branches of the facial nerve that typically emerge from the stylomastoid foramen and enter the parotid gland. In this anatomical context, the posterior belly of the digastric muscle serves as a point of reference. The facial nerve traverses above this muscle, allowing for safe dissection of the gland while minimizing the risk of nerve injury. The preservation of the facial nerve is crucial because it controls the muscles of facial expression. Understanding the relationship between the facial nerve and surrounding structures like the digastric muscles is essential for surgeons performing procedures in the parotid region to avoid complications such as facial paralysis.
