ABSTRACT

This systematic review (SR) aimed to evaluate speech and velopharyngeal function (VPF) changes of patients with cleft palate (CLP) after maxillary advancement (MA) surgery. A two-phase PROSPERO-registered SR (CRD42019141370) was conducted following the PRISMA statements. Search strategies were developed for main databases (PubMed, Scopus, Web of Science, COCHRANE, LILACS, and EBSCOhost) and Grey literature information sources. The GRADE tool was used to evaluate the quality of evidence. From a total of 908 articles, 10 (205 men and 147 women; mean age ranging from 18.0 to 25.7 years) were selected for meta-analysis. Moderate to high risk of bias (Rob) was observed. The most common methods for outcomes evaluation were the Nasometer (speech) and nasoendoscopy (VPF). Speech changed from normal to hypernasal, and VPF worsening were reported in most studies. Comparing maxillary advancement interventions (osteogenic distraction versus Le Fort I), no statistically significant differences were found regarding benefit on speech and VPF. In summary, the effect of MA on speech and VPF remains controversial in CLP patients. The RoB, inconsistencies, and imprecisions severely affected the overall quality of evidence. Further adequately delineated clinical studies are necessary to investigate the potential effect of MA interventions on speech and VPF in CLP patients.

ABSTRACT

This study aimed to evaluate whether pre-emptive analgesia modifies the tissue expression of tumour necrosis factor alpha (TNF-α) and interleukin 1 beta (IL-1ß), and whether there is an association with postoperative surgical outcomes. A triple-blind, randomized, placebo-controlled study of patients undergoing mandibular third molar removal was performed. Volunteers were allocated randomly to receive etoricoxib 120 mg, ibuprofen 400 mg, or placebo 1h before surgery. Twenty-four surgical sites per group were required (95% confidence level and 80% statistical power). Pain scores differed significantly between groups (P<0.001). Etoricoxib and ibuprofen reduced pain scores compared to placebo (P<0.05). Pain scores peaked at 4h postoperative in the experimental groups, but at 2h postoperative in the placebo group (P<0.05). A significant reduction in TNF-α concentration from time 0' to time 30' was seen for ibuprofen (P=0.001) and etoricoxib (P=0.016). The ibuprofen group showed a significant reduction in IL-1ß levels from time 0' to time 30' (P=0.038). In conclusion, TNF-α and IL-1ß levels and the inflammatory events in third molar surgery were inversely associated with the degree of cyclooxygenase 2 selectivity of the non-steroidal anti-inflammatory drugs used pre-emptively. Patients given pre-emptive analgesia showed significant reductions in the clinical parameters pain, trismus, and oedema when compared to the placebo group.
