Three-dimensional versus standard miniplate fixation in the management of mandibular angle fractures : a systematic review and meta-analysis

The aim of the present study was to test whether there is a significant difference in the clinical outcomes between standard and three-dimensional (3D) miniplate fixation in the management of mandibular angle fractures (MAFs). An electronic search without date and language restrictions was performed in October 2013. Inclusion criteria were studies in humans including randomized controlled trials, controlled clinical trials, and retrospective studies, with the aim of comparing the two techniques. Six studies were included. The meta-analyses revealed statistically significant differences for the incidence of hardware failure and postoperative trismus. There were no significant differences in the incidence of postoperative infection, malocclusion, wound dehiscence, non-union/malunion, or paresthesia. The cumulative odds ratio was 0.42, meaning that the use of 3D miniplates in the fixation of MAFs decreases the risk of the event (postoperative complication) by 58%. The results of this meta-analysis showed lower postoperative complication rates with the use of 3D miniplate fixation in comparison with the use of standard miniplate fixation in the management of MAFs

Outcomes of bimanual microincision cataract surgery and 2.2-mm coaxial phacoemulsification

Purpose To compare the efficacy and safety outcomes of bimanual microincision cataract surgery (B-MICS) versus 2.2-mm coaxial phacoemulsification (C-MICS). Patients and methods This prospective, interventional, randomized, comparative clinical study was carried out on 60 cataractous eyes. Thirty patients were managed surgically by C-MICS through a 2.2 mm mean incision and 30 patients were managed surgically by B-MICS through a 1.2–1.4 mm trapezoidal incision. The main outcomes measures were postoperative best-corrected distant visual acuity, postoperative spherical equivalent, higher-order aberrations, corneal thickness, corneal endothelial cell loss (ECL), and complications during and after surgery. Both groups were compared for all variables preoperatively. Results The visual rehabilitation in group B was faster than that in group A (nonsignificant). There were nonstatistically significant differences, in the best-corrected visual acuity, between both groups throughout the postoperative period. The mean ECL was statistically significantly higher in group A (221.2±44.1) compared with group B (167.5±67.9) (P<0.001). The mean central corneal thickness change was significantly greater in group A than group B (P=0.01). The surgically induced astigmatism was statistically significantly improved in B-MICS (group B) than C-MICS (group A) (P=0.001). For the other corneal aberrations, there were nonsignificant differences between the two groups. No differences were found in the complications during surgeries between the two groups of cataract surgery. Conclusion The two techniques are reliable, functional, effective, and yield good visual outcomes and low complication rates. B-MICS with the smallest incision induces less astigmatism (surgically induced astigmatism), less ECL, fewer central corneal thickness changes, and enables earlier visual rehabilitation

Sialolipoma of the superficial lobe of the parotid gland: A case report and literature review

Sialolipoma of the parotid gland is very rare. We report a case of a 38-year-old woman who presented with a painless, slowly growing, mobile lump of the parotid gland. Computed tomography revealed lipoma of the superficial lobe of the parotid gland. Superficial parotidectomy was performed with uneventful postoperative course. The histology showed sialolipoma. Review of the 25 reported cases (including our case) of parotid sialolipoma shows that this tumor is more common in the fifth decade of life, on the left side and the superficial lobe. It has a slight preference for men. Its clinical presentation mimics the standard (pure) parotid lipoma and other more common benign parotid tumors particularly pleomorphic adenoma and Warthin′s tumor. Surgical excision is curative with minor complications and small recurrence rate. Histological examination is necessary to establish the diagnosis and to exclude malignancy
