What Are the Types and Frequencies of Complications Associated With Mandibular Third Molar Coronectomy? A Follow-Up Study.
Coronectomy has been proposed for impacted third molars in close proximity to the inferior alveolar nerve (IAN) to avoid neurologic injury. Immediate (up to 1 month) and late (2 to 36 months) postoperative complications were investigated. ⋯ In this study, coronectomy of mandibular third molars did not result in temporary or permanent injury to the IAN or LN. Coronectomy showed a low rate of postoperative complications. However, within the first year, a second surgery was needed in 6% of coronectomy procedures to remove migrated root fragments. Additional studies with larger patient samples are recommended to further investigate differences in postoperative complications in relation to patient age.

Comparative StudyCan 3'-Deoxy-3'-((18)F) Fluorothymidine Out Perform 2-Deoxy-2-((18)F) Fluoro-D-Glucose Positron Emission Tomography/Computed Tomography in the Diagnosis of Cervical Lymphadenopathy in Patients With Oral/Head and Neck Cancer?
The present study investigated the performance of cellular metabolism imaging with 2-deoxy-2-((18)F) fluoro-D-glucose (FDG) versus cellular proliferation imaging with 3'-deoxy-3'-((18)F) fluorothymidine (FLT) in the detection of cervical lymph node metastases in oral/head and neck cancer. ⋯ FLT showed better overall performance for detecting lymphadenopathy on qualitative assessment within the total nodal population. This notwithstanding, FDG SUV performed better for pathologic discrimination within the visible lymph nodes.

Randomized Controlled Trial Comparative StudyA nasal high-flow system prevents hypoxia in dental patients under intravenous sedation.
Hypoxia is a major complication in dental patients under intravenous sedation (IVS). A nasal high-flow (NHF) system has been reported to achieve effective oxygenation in patients with sleep apnea syndrome. This study investigated the ability of the NHF system to prevent hypoxia in dental patients under IVS. ⋯ These results suggest that use of the NHF system can prevent hypoxia in dental patients under IVS. Further studies are necessary to determine the appropriate flow rate and indications for NHF in obese patients.

Randomized Controlled Trial Comparative StudyA randomized trial to identify the most effective dose of remifentanil during Le Fort I osteotomy.
The Le Fort I osteotomy (L-I) requires extensive dissection and manipulation of tissue, causing hemodynamic instability and an undesirable postoperative stress response. This study aimed to clarify the most effective dose of remifentanil during L-I. ⋯ Remifentanil administration at 0.75 μg/kg/minute stabilized hemodynamics during L-I without major side effects. Results indicated that the standard index of remifentanil administration during L-I should be 0.75 μg/kg/minute when using oxygen, propofol, and remifentanil for general anesthesia.
