Q

A woman has thyroid tumor surgery, but 24 hrs later starts aspirating fluid into her lungs. The area of the piriform recess above the vocal fold of the larynx was anesthetized. What nerve was most likely iatrogenically injured?

  • External branch of the superior pharyngeal
  • Hypoglossal
  • internal branch of the superior laryngeal
  • Lingual
  • Recurrent laryngeal
A

Internal branch of the superior laryngeal

Results in loss of sensation above the vocal cords and loss of taste on teh epigottis; loss of sensation in the laryngeal vestibule precipitates aspiration of fluid into the larynx, trachea, and lungs

Q

Air bubbles on a CT of her brain after thyroidectomy. What caused it?

  • Injury to inferior thyroid artery
  • Injury to inferior an dupserior thyroid arteries
  • Injury to superior thyroid artery and vein
  • Injury to superior an dmiddle thyroid veins
  • Injury to superior, middle, and inferior thyroid veins
A

Injury to superior an dmidle thyroid veins

The superior thyroid vein is from the internal jugular vein and accompanies the superior thyroid artery .The middle thyroid vein is also from the internal jugular vein. Both can be torn in thyroid surgery, admitting an airbubble (due to negative pressure in veins) that can ascend in the internal jugular vein up to the skull.

  • Laceration of the middle meningeal artery
  • Fracture of the cribriform plate with CSF rhinorrhea
  • Aneurysm of the middle cerebral artery

190

A

CSF is mostly secreted from the choroid plexues of the latera, third, and fourth ventricles of the brain -> enters subarachnoid space from fourth ventricle via foramina of Luschka -> circulates in subarachnoid space until resorbed by arachnoid granulations into the superior sagittal sinus.

Thrombus of superior sagittal sinus -> obstruct CSF -> ventricles get enlarged and increased intracranial pressure

25

  • Directly through the site of the umbo
  • Anterior inferior quadrant of the eardrum
  • Vertical incision from the 12 o’clock to the 6 o’clock position of the rim of the eardrum

83

A

Anterior inferior quadrant of the eardrum

Incision of the anterior and posterior-superior quadrants will damage the malleus, which is immediately superior and medial to teh tympanic membrane. The umbo is close to the handle of the malleus. Damage to the malleus -> conductive hearing loss

29
Q

Tumor in the superior orbital fissure. Patient’s eyeball is fixed in an abducted position, slightly depressed, and the pupil is dilated. The upper lid is droopy. When the patient is asked to move the pupil toward the nose, the pupil rotates medially. Consensual corneal reflexes are normal. What nerve was affected?

  • Trochlear
  • Oculomotor
  • Abducens n and sympathetic n plexus accompanying ophthalmic artery
  • Superior division of oculomotor n and nasociliary n

A

Infraorbital n would be affected if that inferior wall was displaced, since it leaves the skull through the infraorbital foramen.

31
Q

Blow-out fracture of the medial wall of the orbit. Pupil of the affected eye can’t turn laterally. What muscle is most likely injured or trapped?

  • Lateral rectus
  • Medial and inferior recti
  • Medial rectus
  • Medial rectus and superior oblique
  • Inferior rectus

161

A

Medial rectus is entrapped- there was no nerve damage here and the muscle is not paralyzed.

Responsible for adduction, but in this case, it acts as a tether/anchor on the eyeball, preventing abduction. Lateral rectus is responsibel for abduction, and damage to it would result in an inability to move the eye laterally.

32
Q

Blow-out fracture of the inferior wall of the orbit. Can’t turn eye upwards. What muscles are most likely injured?

  • Inf rectus and inf oblique
  • Medial and inferior recti
  • Inferior oblique
  • Medial rectus, inferior rectus, and inferior oblique
  • Inferior rectus
A

Inferior rectus and inferior oblique are entrapped

The superior rectus and inferior oblique are responsible for upward movement, but in thsi case, the broken orbital plate of the maxilla entrapped the inferior rectus and inferior oblique muscles, causing them to act as anchors preventing upward movement.

162

33
Q

Absence of accommodation reflex. What was most likely involved?

  • Superior salivatory nucleus
  • superior cervical ganglion
  • nervus intermedius
  • edinger-westphal nucleus

  • Optic
  • oculomotor
  • trigeminal
  • abducens
  • facial
A

Trigeminal

Both eyes blinked when the corneal reflex was elicited, so the facial nerve is fine. It has to be the afferent limb of the blink reflex that’s damaged

37
Q

  • Ability to detect foreign body on cornea
  • Sensation over the anterior scalp
  • Sensation to th eupper eyelid
  • Ability to abduct the eye
A

Secretions from right lacrimal gland

The nerves responsible for lacrimal secretion pass through the lateral part of the superior orbital fissure. Fracture at the base of the orbit would affect structures in the medial part of the fissure (sympathetics, superior ophthalmic vein, CN6, nasociliary n, and divisions of oculomotor), which is closer to the apex of the orbit.

294

40
Q

Bruising of the inferior skin of the eye. Pupillary light reflexes are nromal. Depressed fracture of the frontal process of the zygomatic bone involving the orbit. What is a likely consequence?

  • Trigeminal motor nucleus
  • Dorsal motor nucleus
  • Nucleus ambiguus
  • Superior or inferior ganglia vagus
A

Nucleus ambiguus holds the efferent motor fibers of the vagus nerve, which supply the laryngeal pharyngeal muscles; without it, no swallowing, coughing, or gagging reflex.

  • Superior ganglion of vagus is for general somatic afferents
  • Inferior ganglion of vagus is visceral afferent
  • Nucleus solitarius is for sensation & taste from glosspharyngeal, facial, and vagus nerves.
44
Q

Tumor in middle ear invades through the bony floor. Which will most likely be affected?

  • Cochlea and lateral semicircular canal
  • ICA
  • Sigmoid venous sinus
  • Internal jugular bulb
  • Aditus ad antrum of the mastoid region and the facial nerve

135

A

Internal jugular bulb

The sigmoid sinus collects venous blood and empties it into the jugular bulb, the inferior portion of which is located beneath the bony floor of the middle ear.

Paraganglioma: middle ear tumor on jugular bulb blocks flow from that side of the brain, so the venous system of the other side gets swollen
