CRANIOFACIAL MJS Flashcards
You are treating a Markowitz III NOE via a bicoronal approach. You are doing transnasal wiring. Where do you put your drillholes
1-2mm Posterior to lacrimal fossa and inferior to the lacrimal crest. You want to over correct a little bit because telecanthus is so common.
Indications for ORIF of a condyle
- displacement of condyle into middle cranial fossa
- impossible to get adequate occlusion
- foreign body in the joint
- lateral extracapsular displacment of condyle
You see a patient with epibulbar dermoids. What condition do they have

DIFFERENCE BETWEEN OVERBITE AND OVERJET IN ORTHONATHICS
overjet is the horizontal relationship between maxillary and mandibular incisors. overbite is the vertical overlap between the maxillary and mandibular incisiors.
lack of formation of mandibular ramus and condyle typica for which condition

what are the contents of the anterior triangle of the neck
carotid sheath, CN 9, 10, 12, submandibular gland, tail of parotid, lymph nodes
what are the contents of the posterior triangle of the neck
Accessory nerve, phrenic nerve, brachial plexus, lymph nodes
what are the ducts for paroid gland, submandibular gland and sublingual gland

RFFF, UFFF, ALT, Lateral Arm, PAP
Neurologic innervation of glands of face
Parotid: auriculotemporal, CN 7, GAN, sympathetic plexus
Meibomian and lacrimal glands: lacrimal nerve (V1)
-orbital lobe: reflex secreter
-palpebral lobe: main secretor
Sublingual gland: lingual (V3)
Submandibular gland: chorda tympani (CN 7), submandibular ganglion (branch of lingual [V3]), and mylohyoid nerve (V3)
Fibrous dysplasica is associated with malignant transformation to what?
osteosarcoma
Define Lefort I, Lefort II and Lefort III
Le Fort I is a transverse fracture of the maxilla involving the
ZM and NM buttresses.
○ Le Fort II is a pyramidal fracture involving the ZM buttress,
inferior orbital rim, inferior and medial orbital wall, and
NF region.
○ Le Fort III causes craniofacial dysjunction and involves
the zygomatic arch, lateral orbital rim, lateral orbital
wall, orbital floor, medial orbital wall, and
NF region.
