Prevention of Flap Dehiscence

Prevention of Flap Dehiscence Flap margin dehiscence (separation) is prevented by approximatmg the edges of the flap over healthy bone by gently handling the flap’s edges. and by not placing the flap under tension. Dehiscence exposes underlying bone, producing pain, hone loss, and increased scarring .

Prevention of flap Necrosis

Prevention of flap Necrosis Flap necrosis can be prevented if the eon a ends to four basic principles. First, the apex (tip of a flap should never be wider than the base, unless a major artery is present in the base. Flaps should have sides hat either run par- FIG. 3-1 A, Proper method of making incision usinq no. 15 scalpel blade. Note scalpel motion madeby moving hand at wrist and not by moving entire forearm.

flAP DESIGN

FLAP DESIGN Surgical flaps are made ta gain surgical access or to inove tissue from one place to another, principles of flap design must be followed 0 prevent complications of flap surgery: flap necrosis, dehiscenc and tearing.  

INCISIONS

INCISIONS Many oral and maxillofacial surgical procedures necessitate incisions. A few basic principles are important to remember when performing incisions. The first principle is that a sharp blade of the proper size should be used. A sharp blade allows incisions to be made cleanly, without unnecessary damage caused by repeated strokes. The rate at which a blade dulls depends on the resistance of tissues thr

ASEPTIC TECHNIQUE

ASEPTIC TECHNIQUE Aseptic technique includes minimizing wound contamination by pathogenic microbes. This important surgical principle 1s discussed in detail in Chapter  5.

BASIC NECESSITIES FOR SURGERY

BASIC NECESSITIES FOR SURGERY Little differerrce exists between the basic necessities required far oral surgery and those required far the proper performance of ather aspects of dentistry. The two principal requirements are (1) adequate visibility and (2) assistance. Although visibility may seem too obvious ta mention as a requirement far performing surgery, clinicians often overlook it. Adequate visibility d

DEVELOPING A SURGICAL DIAGNOSIS

DEVELOPING A SURGICAL DIAGNOSIS Most of the important decislons concerning a maxillofacial surgical procedure should be made long before the administration of anesthesia. The decision to perform surgery should be the culmination of several diagnostic steps be the analytic approach the surgeon first identifies tile varfPus signs and symptoms and relevant historical. information; then, using available data and
