3. PRINCIPLES OF SURGERY  Human tissues ,due to their innate properties ,react to injury fairly predictably. So ,with experience certain set principles are evolved for optimal healing.These are called as BASIC PRINCIPLES OF SURGERY.
4. DEVELOPING A SURGICAL DIAGNOSIS Important decisions regarding surgery are made from : Identifying signs and symptoms by 1. Complete and thorough history 2. Physical examination Radiographic findings Laboratory investigations Record keeping/data in an organized form Differential diagnosis
5. BASIC NECESSITIES FOR SURGERY 1. Adequate visibility is based on  Adequate access- m o uth o p e ning , s urg ic a l e x p o s ure , re tra c tio n Adequate light  Surgical field free of excess blood and other fluids. 2. Assistance 
6. ASEPTIC TECHNIQUE It includes minimizing wound contamination by pathogenic microbes through:  Medical asepsis  Surgical asepsis
7. ASEPTIC TECHNIQUE(CONTD..) 1. 2. 3.    Universal precautions are applied to prevent sepsis and efforts fall under the following headings. Instrument sterilization. Operatory disinfection. Surgical staff preparation. Hand and arm preparation. Clean technique. Sterile technique.
8. INCISIONS      Incisions are necessary for many OMFS procedures. The following principles apply. Use a sharp blade of proper size . Use firm continuous strokes. Avoid cutting vital structures. Incise perpendicular to the epithelial surface. Intraoral incisions should be properly placed.
9. FLAP DESIGN 1. 2. 3. Principles of flap design help to prevent: Flap necrosis. Flap dehiscence Flap tearing.
10. 1.Preventing flap necrosis 1. 2. 3. 4. The tip should never be wider than the base unless a major artery is present at the base. The length of a flap should be no more than twice the width. In the oral cavity, the length should never exceed the width. When possible, include an axial blood supply in the base

Emphasizing both the science and craft of surgery, Fischer’s Mastery of Surgery, Sixth Edition, embraces a scope consistent with the broad training of a general surgeon, providing extensive coverage of vascular surgery as well as of common thoracic, breast, esophageal, endocrine, colorectal, gastric, pancreatic, liver, and biliary procedures.   Organized for ease of use, each procedural chapter reviews the essentials of diagnosis, anatomy, and pre-operative planning, but focuses most heavily on step-by-step depictions and descriptions of procedures. Each chapter concludes, as is traditional for this classic text, with an editorial commentary that puts the chapter material in a broad context and provides helpful critiques of the most recent literature.

The path to surgical mastery begins here!
* Step-by-step guidance takes readers through each procedure, with tips and cautions from leading surgeons.
* More than 3,400 illustrations offer a surgeon’s-eye-view of the most advanced approaches.
*Over 450 renowned contributors share their surgical expertise with readers. 
* Focus on evidence-based surgery reveals the science behind each approach.
* A companion website includes the fully searchable text and exclusive web-only chapters not found in the text.

NEW in the Sixth Edition…
* Over a dozen new chapters address endovascular treatment of varicose veins, fasciotomy, minimally invasive parathyroidectomy, reconstruction of the chest wall, thoracic aortic transaction, vascular injury to extremities.
*Fully updated material details the latest developments in vascular procedures, including both open and endovascular procedures.  
* New full-color design throughout the text, including many new color images, help readers visualize and remember key anatomic features and surgical techniques
