Long-term clinical outcome analysis of poly-methyl-methacrylate cranioplasty for large skull defects.
The goal of secondary cranioplasty is permanent cerebral protection in an esthetically acceptable fashion. Reconstruction of cranial defects can be performed with several different materials. Alloplastic materials, such as preformed methyl-methacrylate (PMMA) cranioplasties, are an alternative frequently used at our institution. This retrospective analysis was designed to review the outcomes of PMMA cranioplasty for skull defect reconstruction. ⋯ The results of previous studies have shown that infection and complication rates of cranioplasties accomplished with bone cement are substantially higher, that titanium-based implants may obscure follow-up imaging for tumor patients, and that the outcomes regarding hydroxyapatite-based ceramics, although similar to PMMA, are associated with a much higher cost. PMMA remains a cost-effective and proven method to repair cranial defects that fulfills the goals of cranial reconstruction for skull defects.

Comparative StudyEffectiveness of treatment apnea-hypopnea index: a mathematical estimate of the true apnea-hypopnea index in the home setting.
To present a new measurement instrument, the Effectiveness of Treatment Apnea-Hypopnea Index (ET-AHI), which the authors developed to determine an estimate of the therapeutic control of obstructive sleep apnea (OSA). ⋯ The ET-AHI has the potential to significantly affect the care of patients with OSA because it may provide the treating clinician with a valuable tool to estimate the control of OSA for any therapeutic intervention. How closely the ET-AHI predicts the true effective AHI in the home setting requires further validation.

Randomized Controlled Trial Comparative StudyHealing of intraoral wounds closed using silk sutures and isoamyl 2-cyanoacrylate glue: a comparative clinical and histologic study.
To compare the clinical and histologic healing of intraoral wounds closed using No. 3-0 silk suture with that obtained with isoamyl 2-cyanoacrylate glue. ⋯ On the seventh postoperative day, both clinical and histologic indicators of inflammation were higher on the sutured side, but these indicators had reached similar values on the fourteenth postoperative day on both the sutured and glued sides. This suggests that isoamyl 2-cyanoacrylate may aid initial healing.

Comparative StudyAssessment of blood loss and need for transfusion during bimaxillary surgery with or without maxillary setback.
The objective of this study was to compare the blood loss, transfusion needs, and operation times in subjects who underwent bimaxillary surgery with versus without maxillary setback. ⋯ This study shows that intraoperative bleeding and operation time increased significantly in patients undergoing mandibular ramus osteotomy and Le Fort I osteotomy with maxillary setback. However, transfusion generally is not required during 2-jaw surgery, regardless of maxillary setback.
