Clinical correlates Flashcards
What is lymphadenitis and how would you recognize it?
Inflammation of superficial lymphatic vessels, characterized by painful reddish streaks beneath the skin.
What is shingles?
It is a viral infection of the face supplied by the opthalmic n.
So cornea is involved and spread of infection may go to III, IV, VI and lead to paralysis of associate m.’s
What is the best way to administer local anesthesia to the middle of the face?
Local anestetic infiltration of infraorbial n. in infraorbital foramen
If the structures in the stylomastoid foramen are compressed, what is the effect?
Bell’s Palsy; basically the branchial motor nerves of facial n. that innervate the m’s of facial expression will not work. So the affected side will have face drooping.
NOTE: drooping side translates to opposite side lesion.
An anesthesiologist will measure the pulse of his pt at which point of the entire body but the head is draped?
The superficial temporal a. is palpated just anterior to the auricle.
Where do you inject anestetic when you want to numb:
- All branches of CN V3
- The mandibular teeth (for a dental procedure)
- Just the mental n. (eg to place suture in skin of chin)
- thru mandibular notch to roof of infratemporal fossa
- At lingula of the mandible (blocks inf. alv. n.)
- The mental foramen
What is mumps and how is it presented?
It’s a viral infection of the parotid gland, resulting in inflammation. Pain is due to stimulation of the auriculotemporal n. and swelling limited by the parotid sheath (tough facial capsule)
Extradural hemorrhage following a blow to the head is often due to
Tearing of the middle meningeal a. which causes a rise in intracranial pressure possibly forcing part of the cerebellum through the foramen magnum, compressing the medulla which is life-threatening.
A fracture at the base of the skull that tear the internal carotid may lead to?
Arterial blood rushing into the venous system aka ARTERIOVENOUS FISTULA.
The a. blood will force into the opth. veins and cause the eye and conjuctiva to bulge. The eye will pulse in synchrony w/ the radial pulse.
What is a transient ischemic attack (TIA)?
It is a small stroke (ie the sudden loss of circulation into a region of the brain by hemorrage or occlusion) caused by a soft emboli
What is Horner’s syndrome?
Interruption of the cervical sympathetic trunk. This results in ptosis (b/c paralysis of superior tarsal m.) and constricted pupil
What is the stapedius m. innervated by?
Malfuction of this nerve results in what?
Facial n.
Malfunction results in hyperacusia, a condition in which loud noise is more painful due to loss of dampening of the stapes.
What is sensorineural hearing loss and conductive hearing loss?
hearing loss due to Inner ear (can result in high tone deafness due to persistent exposure to loud sounds, this is difficult to fix) and middle ear problems respectively.
The pharynx etends from the cranial base to:
Where do most of nasopharyngeal cancers originate?
C6;
pharyngeal recess
The most severe nose bleeds occur from rupture of the __ a.
Sphenopalatine a.
(usually ruptured just after it enters the nasal cavity).
