320.A 73-year-old man presents because of repeated, biting of his tongue
and cheek, and some difficulty chewing in general. You examine him and
note that the left side of his tongue is somewhat swollen and that he has
two different cuts on it. His left cheek is slightly less full over the angle of
the mandible compared to the right side. During your physical exam you
note that he has very little sensation over his left mandible and up along the
side of his head, and on the left side of his tongue and that he has weak-
ened ability to elevate his jaw on the left side. Taste sensation on his tongue
is normal. He also complains of a slightly dry mouth on the left side. The
rest of his cranial nerve exam is normal. You send him for a head CT
because you suspect which of the following?
a. A tumor at the left superior orbital fissure
b. A tumor blocking the left foramen rotundum
c. A tumor blocking left foramen ovale
d. A tumor blocking the left internal acoustic meatus
e. A tumor blocking the right internal acoustic meatus
321.A 43-year-old man comes to your office presenting with left-sided
maxillary tooth pain of one week’s duration. Because he thought it might
have been one of his maxillary fillings (the newer plastic polymers) he vis-
ited his dentist first, but his dentist could not find any dental problems.
You tap on his maxillae and elicit sharp pain when you tap on the left but
not right side of his face. While he does not think he has any allergies he
admits that his girlfriend has recently bought a cat that lives inside. You
send him for a sinus series because you suspect which of the following?
a. Sphenoid sinusitis
b. Anterior ethmoidal sinusitis
c. Posterior ethmoidal sinusitis
d. Maxillary sinusitis
e. Frontal sinusitis
