The parotid gland is predominantly related to the facial nerve. Which layer of deep cervical fascia forms the parotid fascia and contributes to 'parotid space'?
- A Pretracheal layer of deep cervical fascia
- B Investing (superficial) layer of deep cervical fascia ✓
- C Prevertebral layer of deep cervical fascia
- D Carotid sheath
Correct answer: B. Investing (superficial) layer of deep cervical fascia
Explanation
The investing layer (superficial layer) of deep cervical fascia splits to enclose both the parotid gland and the submandibular gland, forming their respective capsules. This tight fibrous capsule is the reason why parotid abscess causes excruciating pain — the unyielding fascia prevents swelling. The pretracheal fascia encloses the thyroid gland and the trachea, while the prevertebral fascia overlies the cervical vertebrae.
