Advanced Parotid Gland Quiz

Q1. Why is facial nerve identification a major priority during parotidectomy?

• The facial nerve is the gland's only arterial supply
• The facial nerve branches within the gland and injury can weaken muscles of facial expression
• The facial nerve forms the parotid duct
• The facial nerve controls tongue sensation through the gland

Q2. Why can parotid swelling be particularly painful?

• The parotid duct contracts strongly during inflammation
• The dense parotid fascial capsule restricts expansion during swelling
• The gland lies completely inside bone
• The gland has no sensory innervation

Q3. Why can parotid disease cause referred pain toward the temporal or auricular region?

• The parotid duct opens into the external acoustic meatus
• The optic nerve passes through the gland
• The hypoglossal nerve supplies the temporal scalp
• Shared sensory pathways through the auriculotemporal nerve can refer pain toward its regional distribution

Q4. Why can gustatory sweating occur after parotid surgery?

• Facial motor fibers regenerate into the parotid duct
• The external carotid artery directly stimulates sweat glands
• The great auricular nerve becomes a parasympathetic nerve
• Misguided regeneration of auriculotemporal secretomotor fibers can activate cutaneous sweat glands during eating

Q5. Why does a lesion of the lesser petrosal nerve reduce parotid secretion?

• It interrupts preganglionic parasympathetic fibers traveling to the otic ganglion
• It removes sympathetic fibers from the superior cervical ganglion
• It severs the facial nerve branches within the gland
• It blocks the submandibular ganglion

Q6. Why does damage to the auriculotemporal nerve proximal to its parotid branches potentially reduce parotid secretion?

• It is the only motor nerve to buccinator
• It carries preganglionic fibers from the facial nerve
• It supplies the gland through the submandibular ganglion
• It carries postganglionic secretomotor fibers from the otic ganglion to the gland

Q7. Why can a deep parotid mass project toward the lateral pharyngeal region?

• The superficial lobe lies inside the pharyngeal lumen
• The parotid duct enters the nasopharynx
• The deep gland extends medially toward the parapharyngeal region
• The gland extends through the foramen magnum

Q8. Why is the superficial-to-deep arrangement of facial nerve, retromandibular vein, and external carotid artery surgically useful?

• It provides a predictable neurovascular sequence for safe intraparotid dissection
• It describes the layers of the tympanic membrane
• It identifies the order of salivary duct openings in the mouth
• It predicts the branches of the lingual nerve

Q9. Why can injury to the great auricular nerve during a parotid approach cause numbness around the lower auricle?

• It carries parotid secretomotor fibers from the otic ganglion
• It provides taste to the posterior tongue
• The great auricular nerve supplies skin over the parotid region and lower auricle
• It supplies motor fibers to the facial muscles

Q10. Which statement best integrates the parotid gland's neural anatomy?

• The facial nerve both traverses the gland and provides all of its secretomotor supply
• The vagus nerve synapses in the ciliary ganglion before entering the gland
• The hypoglossal nerve supplies the gland through the submandibular ganglion
• Facial motor branches traverse the gland, while glossopharyngeal-derived secretomotor fibers reach it through the otic ganglion and auriculotemporal nerve
