Intraoperative and perioperative complications in anterior maxillary osteotomy: a retrospective evaluation of 103 patients.
OBJECTIVE
To study the intraoperative and perioperative complications associated with anterior maxillary osteotomy (AMO), and assess its safety and predictability in orthognathic surgery.


METHODS
We performed a retrospective evaluation of 103 patients undergoing AMO as a single procedure, or in combination with other osteotomies over a period of 5 years, with a mean follow-up of 3 years.


RESULTS
Twenty-seven (26.2%) patients in our series of 103 had complications of varying severity: 43.3% of these were soft tissue-related, and 36.6% were attributable to dental causes. All other complications accounted for the remaining 20%.


CONCLUSIONS
Although its indications are limited, AMO is a safe and reliable procedure in routine orthognathic surgery.
