❏ 6 months - usually closes at 6-8 weeks
... [Show More] (1-2mos)
❏ 12 months
❏ 18 months
❏ 24 months
2. A patient who figured in a vehicular accident suffered a fracture on the temporal bone traversing the petrous portion. Which of the following clinical manifestations is consistent with this injury?
❏ Ptosis → CN III and cervical sympathetic
❏ Facial numbness → CN V
❏ Hearing loss → CN VIII
❏ Loss of efferent limb of gag reflex → CN X
*petrous portion of temporal bone→ posterior boundary of middle cranial fossa where Internal Acoustic Meatus (CN 7 and 8 passes) is found
3. A tumor invading the jugular foramen may cause the patient to experience which of the following symptoms?
❏ Deviation of mandible to contralateral side → in fractures, CN V
❏ Loss of pain sensation in anterior 2/3 of tongue → CN VII
❏ Vertigo → CN 7
❏ Aspiration→ CN 9, 10
* Jugular Foramen - CN IX, X, X1, IJV passes through
4. Which of the following limbs of the cranial nerve reflexes will be affected with tumor invading the internal acoustic meatus?
❏ Efferent limb of the light reflex → CN III
❏ Efferent limb of the corneal reflex → CN VII
❏ Afferent limb of the gag reflex → CN IX
❏ Efferent limb of the gag reflex → CN X
*Internal Acoustic Meatus - CN VII & VIII passes through
5. Which of the following structures is responsible for the gaping of wound in the scalp?
❏ Skin → sebaceous and sweat glands are found
❏ Subcutaneous tissue → blood vessels are found
❏ Galea aponeurotica → due to contraction of the muscles attached, frontalis and occipitalis muscle
❏ Periosteum → has no osteogenic capability
6. Increase in orbital volume is consistent with which of the following facial fractures?
❏ Orbital blow in → decrease in intraorbital volume
❏ Orbital blow out → Fracture in floor of orbit due to increased intraorbital pressure and volume; enopthalmos, difficulty in upward gaze, orbital emphysema due to fracture of paranasal sinus (ethmoid sinus), malar region numbness
❏ Orbitozygomatic → Fracture to the lateral orbital wall
❏ Craniofacial disarticulation → occurs in multiple fractures of face
7. Hacking wound to the posterior triangle of the neck injured a neural structure. Which of the following clinical manifestations is consistent with the location of the injury?
❏ Facial weakness → CN VII
❏ Hoarseness → CN IX
❏ Dysphagia → CN IX, X
❏ Inability to raise the shoulder → CN XI (Spinal accessory passes along SCM from posterior triangle of the neck, cervical plexus also passes anteromedially)
8. Malignancy from the palatine tonsils will metastasize first in what lymph node level?
❏ I → submental/submandibular
❏ II → upper jugular
❏ III → oral cavity, oropharynx, nasopharynx
❏ IV → hypopharynx, larynx
9. A maneuver used to test presence of hypocalcemia, in which the parotid gland over the facial nerve is tapped to elicit ipsilateral facial twitching:
❏ Chvostek’s
❏ Trousseau’s → carpopedal spasm induced by ischemia secondary to the inflation of a sphygmomanometer cuff, to 20 mmHg over their systolic blood pressure for 3 minutes
❏ → stroking the lateral sole of foot towards the big toe resulting to
s;
❏ → evaluate patients with goiter elicited by
n injury
→
from thyroid obstructing thoracic inlet due to inc venous return
10. The thyroid gland is enveloped by which cervical fascial layer?
❏ Superficial → subcutaneous tissue and platysma muscles
❏ Investing → encloses parotid and submandibular glands
❏ Visceral → superior: Hyoid and
thyroid cartilage, Inferior: great vessels of neck to pericardium; encloses strap muscles and visceral muscles of
pharynx, larynx, trachea and esophagus
❏ Pre-vertebral → forms floor of posterior triangle, located anterior to vertebra
*Deep fascia comprises investing, visceral and prevertebral
11.
of the following cranial n.?
to the submandibular gland is carried by which
❏ Auriculotemporal → Branch of trigeminal nerve → subserves fibers of parotid gland
❏ Chorda tympani → branch of facial nerve that passes in middle ear to infratemporal fossa
❏ Mandibular [Show Less]
