Randomized Controlled TrialInduced hypotension in orthognathic surgery: a comparative study of 2 pharmacological protocols.
The objective of this comparative study was to report on the use of 2 different pharmaceutical protocols involving 2 different anesthetic techniques (IV and balanced) to induce hypotension in patients submitted to orthognathic surgery by assessing the patients' intra- and postoperative physiologic response and hemodynamic stability. ⋯ Both protocols tried in this study proved to be effective and safe, and they seem to be interesting alternatives in longer orthognathic surgeries with the expectation of an important blood loss. The choice for either protocol should be based on the inherent risks involved in their use and their cost-benefit ratio.

Controlled Clinical TrialMicrovascular free tissue transfer for tongue reconstruction after hemiglossectomy: a functional assessment of radial forearm versus anterolateral thigh flap.
The purpose of this study was to evaluate tongue function and donor site morbidity in patients with oral cancer surgically treated and reconstructed with radial or anterolateral thigh free flaps. ⋯ Anterolateral thigh flap, with its versatility in design, long pedicle with a suitable vessel diameter, and low donor site morbidity, could be the ideal flap for hemiglossectomy defect reconstruction.

Trauma to the zygomatic arch classically leads to 1 of 3 injury patterns: fracture with medial displacement, fracture with posterior telescoping, or explosive burst with lateral displacement. We identified an additional injury pattern whereby the arch undergoes significant bending in the axial plane without fracture. ⋯ Zygomatic arch deformation without fracture occurs in 19% of zygoma injuries in our group and is likely elastic in nature. We believe this injury pattern is important clinically as it may decrease the need for coronal exposure, facilitate anatomic repair, and provide stability without hardware fixation.

Recovery after orthognathic surgery: short-term health-related quality of life outcomes.
The purpose of this study was to assess the patient-reported time to recovery for quality of life outcomes: postsurgery sequelae, discomfort/pain, oral function, and daily activities after orthognathic surgery. ⋯ Comprehensive daily postoperative patient quality of life data provides the orthognathic surgeon with estimated recovery times in distinct domains. This information is vital in the provision of informed consent as well as preoperative education of patients regarding perioperative and postoperative expectations. Ultimately this data can be combined with individual risk factors to provide personalized consent and expectations as well as tailor perioperative and postoperative management regimens.

Randomized Controlled TrialNitroglycerin- and nicardipine-induced hypotension does not affect cerebral oxygen saturation and postoperative cognitive function in patients undergoing orthognathic surgery.
The aim of this study was to investigate the influence of nitroglycerin- and nicardipine-induced hypotension on regional cerebral oxygen saturation (rSO(2)) and postoperative cognitive function in patients undergoing orthognathic surgery. ⋯ Cerebral oxygen saturation and postoperative cognitive function were not impaired during nitroglycerin- and nicardipine-induced hypotension in patients undergoing orthognathic surgery.
