... freeing the periosteum from its lateral surface. The periosteal elevator can then be used to continue bluntly dissecting inferiorly with the black-and-forth motion, taking care not to dissect ... into the TMJ capsule (Fig. 1 2-1 0). Blunt dissection with scissors can also be used to dissect inferiorly to the zygomatic arch. Once the dissection is approximately 1 cm be...

The periosteal elevator ... inferior to the lowest part of the bony external auditory meatus (Fig. 1 0-1 ). The average distance from the lowest point on the external bony auditory meatus...

... superior limb of the tendon. An effective method to pass this suture is to identify the superior limb of the canthal tendon first with small, toothed forceps placed into the incision. The forceps are ... retractors, a scalpel is used to icise the periorbita, taking care to stay lateral to the lacrimal sac (Fig. 3-1 1). The incision through the periorbita is just...

The nerves provide motor innervation to the frontalis, the ... 6-4 Branches of the facial nerve.

The tension throu g h p eriosteum should be 3 to 4 cm su p erior to the orbital rims. 75 Figure 6- 10 Draping of the patient and the ... and inferior to where the artery pierces the medial orbital wall. With a periosteal elevator on each side of the foramen, retraction allows the periosteum att...

S E C T I O N IV TRANSORAL APPROACHES TO THE FACIAL SKELETON The midfacial and mandibular skeleton can ... in the midface. It allows relatively safe access to the entire facial surface of the midfacial skeleton, from the zygomatic arch to the infraorbital r...
