Practice questions
- A patient is asked to close the eyes tightly and wrinkle the forehead. Which nerve supplies the muscles producing these movements?
- A patient can clench the teeth normally but has difficulty keeping food between the teeth while chewing. Which muscle is most likely weak?
- After a cheek laceration, a patient cannot whistle effectively, although jaw movements are preserved. Which muscle's dysfunction best explains this finding?
- Following an injury near the lower border of the mandible, a patient has weakness of the lower lip when asked to bare the teeth. Which facial nerve branch is most likely injured?
- A patient is unable to close the eyelids tightly after a peripheral facial nerve injury. Which muscle is directly responsible for the impaired action?
- Which nerve carries most cutaneous sensation from the forehead and anterior scalp?
- A laceration causes numbness of the skin of the cheek and upper lip. Which trigeminal division is most likely involved?
- A small sensory nerve exits the mental foramen and supplies the skin of the chin and lower lip. It is a terminal branch of which nerve?
- During examination of the lower face, where is the facial artery classically palpated as it crosses the mandible?
- A facial artery branch ascends along the side of the nose and terminates near the medial canthus. Which named continuation is classically described there?
- Which sequence lists the usual named terminal branches of the facial nerve within the parotid region?
- During parotid surgery, which structure is encountered superficial to the retromandibular vein and external carotid artery within the gland?
- A cheek wound crosses the anterior border of the masseter. Which course makes injury to the parotid duct a particular concern?
- Where does the parotid duct normally open into the oral cavity?
- A parotid duct injury is suspected after a penetrating cheek wound. Which muscle does the duct pierce before entering the oral vestibule?
- Which structure lies immediately deep to the parotid gland and forms an important landmark in the region?
- Which nerve provides the preganglionic parasympathetic pathway that ultimately stimulates parotid secretion?
- A surgeon is planning a parotidectomy. Which statement about the facial nerve is anatomically correct?
- A patient develops flushing and sweating over the parotid region while eating months after parotid surgery. What is the most likely explanation?
- A patient has weakness of the entire ipsilateral face, including inability to wrinkle the forehead and close the eye. Which lesion is most consistent with this pattern?
- Which lymph-node group commonly receives lymph from much of the cheek and lateral face before drainage to the deep cervical chain?
- A lesion of the central lower lip is being assessed for regional lymphatic spread. Which nodal group is especially relevant for drainage from the central lower lip and chin?
- Which statement best describes the relationship between the facial nerve and the parotid gland?
- A lower-face filler procedure is planned near the mandibular region. Which approach is specifically emphasized in the supplied ultrasound guidance article to improve anatomic safety?
- Which set of structures is specifically highlighted for sonographic identification during lower-face filler planning?
- According to the supplied lower-face filler guidance, which complication is among the risks that ultrasound-guided scanning aims to reduce?
- A patient presents with a facial laceration. Which sequence best reflects the initial priorities described in the supplied review of facial soft-tissue injuries?
- A laceration occurs over the cheek near the parotid region. Which pair of structures is specifically identified as requiring attention in facial soft-tissue injury assessment?
- A young adult has a slowly enlarging parotid-region mass. Which conclusion is justified by a reported case of embryonal rhabdomyosarcoma mimicking a primary parotid tumor?
- In the supplied case report of facial cutaneous squamous cell carcinoma invading the parotid, which operative principle was demonstrated?
