Risk factors for neurosensory disturbance after bilateral sagittal split osteotomy based on position of mandibular canal and morphology of mandibular angle.
The aim of the present study was to evaluate the potential morphologic risk factors for postoperative neurosensory disturbance (NSD) after bilateral sagittal split osteotomy. ⋯ The frequency of NSD after bilateral sagittal split osteotomy in Class III cases was dependent not only on the position of mandibular canal, but also on the length of the mandibular angle. A lateral course of the mandibular canal and a long mandibular angle appeared to result in a high risk of injury to the inferior alveolar nerve, resulting in NSD owing to a compromised splitting procedure.

Randomized Controlled Trial Comparative StudyIs clonidine an adequate alternative to epinephrine as a vasoconstrictor in patients with hypertension?
To evaluate the safety and efficacy of an admixture of lidocaine with clonidine with regard to the anesthetic abilities, hemodynamic parameters, and postoperative pain control and to compare the results with those obtained with a lidocaine-epinephrine solution. ⋯ Clonidine could be a useful and safe alternative to epinephrine for intraoral block anesthesia with lidocaine in patients with hypertension and American Society of Anesthesiologists class II.

Verification of nerve integrity after surgical intervention using quantitative sensory testing.
The aim of this study was to apply a standardized Quantitative Sensory Testing (QST) approach in patients to investigate whether oral surgery can lead to sensory changes, even if the patients do not report any sensory disturbances. Furthermore, this study determines the degree and duration of possible neuronal hyperexcitability due to local inflammatory trauma after oral surgery. ⋯ The results show that oral surgery can lead to sensory deficits in the mental and lingual region, even if the patients do not notice any sensory disturbances. The applied QST battery is a useful tool to investigate trigeminal nerve function in the early postoperative period. In light of the increasing forensic implication, this tool can serve to objectify clinical findings.

Subjective outcomes of maxillomandibular advancement surgery for treatment of obstructive sleep apnea syndrome.
To evaluate subjective outcomes and use of continuous positive airway pressure (CPAP) after maxillomandibular advancement surgery for treatment of obstructive sleep apnea syndrome (OSAS). ⋯ Maxillomandibular advancement surgery for treatment of OSAS is very effective at improving excessive daytime sleepiness, snoring, and witnessed apneas. Most patients in this study were able to discontinue the use of CPAP after surgery. Overall, patients reported the treatment to be worthwhile and would recommend it to others.

ReviewPET-MRI fusion in head-and-neck oncology: current status and implications for hybrid PET/MRI.
To review the current status and clinical effect of PET-MRI image fusion in the staging of head-and-neck cancer and to show its implications for imaging with future hybrid PET/MRI scanners. ⋯ Combined PET/MRI scanners might overcome the above-named problems. Both sequential and fully integrated PET/MRI scanners are now available in selected departments, and future studies will show whether hybrid PET/MRI is of greater clinical value than PET/CT and retrospective image fusion techniques.
