Basic Surgical Techniques (Dos and Don’ts)
摘要
Adequate surgical exposure is the key to any operation. Good exposure starts with proper positioning of the patient. The top of the head should be positioned at the very end of the surgical table, placing the neck in an extended position so the chin is higher than the forehead (Fig. 10.1). Extending the neck lowers the superior orbital rim and eyebrow, improving exposure of the eye.
