Local Injection of Botulinum Toxin Type A to Prevent Postoperative Scar
Background: Physical scars, especially those in the head and neck area, can cause emotional and psychological distress. Recent studies, have suggested that botulinum toxin type A (BTX-A), also known as Botox, may improve surgical scars by speeding up the wound healing process. Injection of BTX-A is generally considered a less invasive approach. Objectives: The purpose of this meta-analysis was to assess the efficacy and safety of BTX-A in the prevention of postoperative scars compared to placebo or no treatment. Materials and methods: Following databases were searched from inception to March 2019: Cochrane Library, EMBASE, Web of Science, PubMed, and Open grey. Five trials registers were searched for potentially related trials. The authors also searched reference lists of relevant articles and contacted the investigators to identify additional published and unpublished studies. Data collection and analysis: Two authors independently evaluated all potential studies that met the selection criteria. Two authors independently extracted and analyzed the data. Results: Analysis was conducted on 267 patients who were enrolled in trials and randomly assigned to receive local injection of BTX-A (184 patients) and placebo (182 patients). Improved Vancouver scar scale scores were noted among patients treated with BTX-A injections compared with the control group (P = .000). The visual analogue scale scores revealed a significant improvement in appearance for the BTX-A-t...

We aimed to evaluate velopharyngeal function and speech outcomes of Sommerlad palatoplasty combined with sphincter pharyngoplasty in surgical repair of cleft palate in patients over five years old. Fifty-eight patients were reviewed between the years 2013 and 2017, 31 of whom were treated with Sommerlad palatoplasty combined with sphincter pharyngoplasty, (mean age 15 (range 9 - 22) years), and 27 were treated with Sommerlad palatoplasty alone (mean age 18 (range 10-25) years). Velopharyngeal function was evaluated by radiographic lateral cephalometry and nasoendoscopy.
AbstractThe incidence of malignant transformation of fibrous dysplasia (FD) is very rare. Thus, the available knowledge of its characteristics, management, and survival is scarce. Here, we present a systemic review of fibrous dysplasia that had undergone malignant transformation. A comprehensive search was performed on PubMed electronic database. The survival rates and hazard ratios of age, gender, past history of previous radiotherapy, type of FD, and treatment were collected from the published articles and analyzed. Forty-eight cases were eligible for inclusion in the study. Patient ’s age, gender, past history rad...
CONCLUSIONS: The cleft palate simulator can be practically implemented with video-recording capability to assess performance in cleft palate repair. This technology may be of assistance in assessing surgical competence in cleft palate repair. PMID: 32394745 [PubMed - in process]
CONCLUSION: The orbit is a rare localization for FD causing aesthetic and functional disabilities. Medical and surgical treatment can be proposed as part of a multidisciplinary approach. PMID: 32376037 [PubMed - as supplied by publisher]

This article discusses using the relationships of the facial anatomic subunits to obtain more consistent and natural facial rejuvenation outcomes.
Craniomaxillofacial injuries account for a large number of emergency attendances and a substantial proportion of the workload of acute clinicians. Although data exist on frequency of involvement of the craniofacial bones, assessments of severity are lacking, and scoring systems for fractures of individual bones and complex craniomaxillofacial trauma often fail to include the frontobasal unit. To rectify this, we have devised a validated scoring system to evaluate the severity of trauma to this region and have merged it with a pre-existing model to create a cohesive craniofacial disruption index.
The aim of this study was to introduce a new computer-guided technique for contouring and shaving of craniofacial fibrous dysplasia involving the zygoma. Computer-guided contouring was performed for five patients with unilateral craniofacial fibrous dysplasia involving the zygoma, using a patient-specific surgical depth guide. This patient-specific guide with depth holes was virtually designed for each patient based on mirroring of the unaffected side. The guide was printed using rapid prototyping.
