Metal plates wired to the teeth to occlude the jaw during maxillofacial surgery or during healing. Arch bars maintain the patient's normal bite --- occlusion.
Screws that penetrate both cortical layers and tghe intervening spongy layer of the bone.
A severe fracture of the orbital cavity in which a portion of the globe may extrude outside the cavity.
Le Fort I fracture
A horizontal fracture of the maxilla that causes the hard palate and alveolar process to become separated from the rest of the maxilla. The fracture extends into the lower nasal septum, lateral maxillary sinus, and palatine bones.
Le Fort II fracture
A fracture that extends from the nasal bone to the frontal processes of the maxilla, lacrimal bones, and inferior orbital floor. It may extend into the orbital foramen. Inferiorly, it extends into the anterior maxillary sinus and the pterygoid plates.
Le Fort III facture
This fracture involves separation of all the facial bones from their cranial base. It includes fracture of the zygoma, maxilla, and nasal bones.
In maxillofacial surgery, this refers to the patient's bite pattern when the jaw is closed.
Surgery involving the bones of the face, primarily for repair of fractures and reconstruction of congenital anomalies.
Excision of Superficial Lesions surgical goal
Skin lesions are removed for diagnostic purposes to and to prevent or treat malignancy.
Excision of Superficial lesions pathology
Malignant lesions usually result form excessive exposure to ultraviolet light - sun or artificial - in combination with genetic susceptibility. The most common are basal and squamous cell carcinoma. Also, malignant melanoma. Malignant melanoma is the important concern.

Draping of the face
is from the sternal notch to behind the hairline and behind the ears. Prepped with Betadine. Split sheet is draped over patient and around face. If mouth will be wired, teeth may be brushed as part of the prep.
Facial injury dressings
are not used. Face heals very quickly. Ray-Teks will be used. Count is necessary because the throat will have these to stop the blood.
Maxillomandibular Fixation MMF is pointed towards anesthesia for ventilation. Wire cutters stay with the patient.
