ANSWERS✔✔ ❏12
Which of the following symptoms is consistent with a middle cranial
fossa injury?
❏Anosmia CN I - anterior cranial fossa
❏Numbness of cheek CN V2 Trigeminal - Middle cranial fossa (also
CN for eye movements)
❏Loss of gag reflex CN IX,X - posterior cranial fossa
,❏Deviation of tongue to affected side CN XII - cranial fossa Parotid -
cervical plexus - ACCURATE ANSWERS✔✔ Numbness of cheek
The pterion is clinically significant especially in traumatic skull injuries
because it:
❏overlies branch of middle meningeal a. which can be torn causing
extradural hematoma
❏can impinge on extraocular m. causing limited eye movement
❏can serve as pathway for cavernous sinus infection
❏can be a source of significant craniofacial deformity if fractured
Pterion at temporal region, where 4 cranial bones meet each other -
ACCURATE ANSWERS✔✔ overlies branch of middle meningeal a.
which can be torn causing extradural hematoma
A tumor invading the internal acoustic meatus may present with which
of the following symptoms?
❏Facial numbness - CN V Trigeminal (middle cranial fossa)
❏Deviation of jaw to the unaffected side
❏Dizziness and hearing loss
❏Deviation of palate to unaffected side - CN IX,X (jugular
foramen),pharyngeal plexus

,Facial nerve (Facial muscles, asymmetry) & Auditory nerve pass
through IAM - ACCURATE ANSWERS✔✔ Dizziness and hearing loss
Infections in this layer of the scalp may lead to cavernous sinus infection
due to presence of emissary veins in this layer:
❏Dense connective tissue
❏Aponeurotic layer - Gaping wound
❏Loose connective tissue - Dangerous area - EV -> diploic veins - > CS
(valveless, can go bidirectional)
❏Pericranium - Cephal hematoma
Subcutaneous - Caput succedaneum - ACCURATE ANSWERS✔✔
❏Loose connective tissue
The sphincter function of the lip may be affected by injury to the nerve
exiting which craniofacial foramen?
❏Infraorbital
❏Mental
❏Stylomastoid - CN VII will carry purely motor fibers upon exiting this
foramen
❏Jugular - CN IX, X, X

❏Coronoid
❏Angle
❏Symphysis - ACCURATE ANSWERS✔✔ Condyle
Post-operative phenomenon characterized by gustatory sweating is a
possible complication of which of the following surgical procedures?
❏Parotidectomy - transection of auriculotemporal nerve which then
joining greater auricular nerve (innervate sweat glands of face) aka
Frey's syndrome
❏Excision of submandibular gland
❏Thyroidectomy
