Effects of hypotensive anesthesia in anterior maxillary osteotomy.
Deliberate hypotension, as a means of reducing loss of blood, providing a more ideal operative field, and shortening operating time, has been used in other surgical disciplines, such as neurosurgery, vascular surgery, and orthopedic surgery. This controlled study compared the effects of hypotensive and normotensive anesthesia on loss of blood, quality of surgical field, and length of surgery in one type of orthognathic surgical procedure--the anterior maxillary osteotomy.
