Effectiveness of glucocorticoids in orthognathic surgery: an overview of systematic reviews

Pre-Surgical Factors Influencing Post-Surgical Outcomes in Orthognathic Surgery Patients: A Longitudinal Study

Background/Objectives: This study aims to assess the relationship between physical and psychosocial pre-surgical factors and post-surgical evolution in patients undergoing orthognathic surgery. Methods: A cohort study with 3 months of follow-up after maxillofacial surgery was conducted. Participants were recruited from the Maxillofacial Surgery Unit of Hospital Universitario La Paz in Madrid, Spain. Primary variables included the range of motion of mouth opening, protrusion tongue force, anxiety, depression and kinesiophobia. Assessments were realised on-site or via video call. Statistical analysis was conducted using mixed-effects models. Results: The initial recruitment yielded 22 patients, with 19 ultimately eligible for analysis. The study found significant impacts of pre-surgical factors on post-surgical evolution. Both ranges of motion and anxiety showed influences from baseline measures, with the range of motion affected by a pre-surgical range of motion (estimate: 3.89) and positive expectations (estimate: 4.83). Anxiety was influenced by both pre-surgical (estimate: 0.48) and baseline anxiety levels (estimate: 0.64). Kinesiophobia demonstrated a trend toward significance, with baseline levels affecting post-surgical evolution (estimate: 0.77). Conclusions: Our results highlight the relationship between pre-surgical factors and post-surgical outcomes in orthognathic surgery patients. Pre-surgical range of motion and positive expectations were found to influence post-surgical range of motion, while pre-surgical anxiety levels impacted post-surgical anxiety evolution. Pre-surgical kinesiophobia also showed potential as a post-surgical kinesiophobia predictor, but further investigation is needed to confirm this relationship.

Current Orthognathic Surgery Practice Patterns Among Academic OMS

OBJECTIVE

Currently there is variation in perioperative care of orthognathic surgery patients and limited clinical practice guidelines. The current orthognathic surgery practice patterns among US academic OMFS training centers have not been described. The purpose of this study is to describe the practice patterns among US academic OMFS training centers.

DESIGN

The study design is cross-sectional. Data was collected through a survey of the sample.

SETTING

OMFS programs in the US.

PARTICIPANTS

Academic OMFS. 573 surgeons were contacted and 85 responses were received.

MAIN OUTCOME MEASURE

Descriptive and bivariate statistics were reported.

RESULTS

Respondents were 87% male and worked in full-time academic (80%), part-time academic (19%), or military settings (1%). Thirty-one percent have practiced for 30 years or more and then 29% with 11-20 years, 18% with 21-30 years, 12% with 6-10 years and 11% with 1-5 years. Twenty-six percent of respondents perform 20-40 orthognathic surgeries a year, 22% perform less than 20 surgeries a year, 21% perform 40-60 surgeries per year, and 19% perform more than 100 surgeries per year. Intraoperatively, 48% of surgeons request a mean arterial pressure of 60-64 mmHg, 25% utilize tranexamic acid (TXA), 85% report a blood loss of less than 400 milliliters, and 93% report a blood transfusion rate of <1%.

CONCLUSION

There are variations in orthognathic surgery practice patterns with limited clinical practice guidelines. Only 13 of the 32 survey questions had a single response holding a simple majority. This study demonstrates the need for further research and evidence-based protocols and decision making.

"Over-reviewing" of research? An analysis of orthodontic reviews

INTRODUCTION

Research overviews may be undertaken to identify gaps in the literature, evaluate existing systematic reviews (SRs), and summarize evidence. This paper aims to profile overviews that have been conducted in orthodontics and related interventions since 2012 and to evaluate the degree of overlap among these overviews.

METHODS

Overviews published between January 1, 2012 and June 20, 2023 were identified using an electronic search involving Google Scholar and PubMed. A descriptive summary was produced, and citation matrices were used to evaluate the percentage of overlap between overviews using corrected covered area and covered area. This was classified as slight, moderate, high, or very high.

RESULTS

A total of 35 overviews were identified across a wide range of topics. Eight overviews included <10 SRs; 21 had 10-20 SRs; and 6 included >20 SRs (median no. of SRs per overview, 15; range, 3-62). Meta-analysis was conducted in only 5 overviews. Overlap between overviews on the same topic ranged from slight (2.7%) to very high (53.8%).

CONCLUSIONS

Almost all overview topics address treatments and their effects, with a wide variation in the number and quality of SRs included. There is considerable overlap in some orthodontic overviews, suggesting unnecessary duplication and research waste. Researchers should be encouraged to focus on primary data collection to add more high-quality data to SRs, which will ultimately enhance the yield from secondary and tertiary orthodontic research.

Postoperative nausea and vomiting in orthognathic surgery: systematic review and meta-analysis

PURPOSE

Postoperative nausea and vomiting (PONV) is a frequently reported adverse event following orthognathic surgery. The aim of this work is to conduct a systematic review of the literature on the subject, and to discuss the role of maxillofacial surgeons and the steps that can be taken to prevent or control PONV in orthognathic surgery.

METHODS

A systematic review was conducted according to the PRISMA guidelines, using the search strategy: (orthognathic AND (nausea OR vomiting)). The authors searched PubMed, Embase, Dimensions, Web of Science and Google Scholar databases, without any language restrictions. RevMan 5.4 was used to create a risk of bias graph and a forest plot.

RESULTS

The included articles were classified as having a low risk of bias, despite the limited literature on the subject. Various measures have been reported to be beneficial in preventing or managing PONV, such as the use of dexamethasone, antiemetic drugs, gastric aspiration, and anesthetic blocks. Effective bleeding control and faster surgeries can also be helpful.

CONCLUSIONS

Throat packs have not been found to be effective in preventing PONV. Although no definitive protocol has been established in the literature, the Enhanced Recovery After Surgery (ERAS) protocol could be a useful approach. Overall, a multimodal approach may be taken to prevent PONV, and further research is needed to establish definitive protocols.

Optimizing drug regimens and supplementation in orthognathic surgery: A comprehensive and practical guide

OBJECTIVE

This study aimed to comprehensively review the literature and provide a practical guide for optimizing drug regimens and supplementation related to orthognathic surgery.

METHODS

The authors conducted a thorough review of the existing literature, following the PRISMA-ScR guidelines. Various types of studies except case reports and reviews were included. The study applied specific inclusion criteria, focusing on perioperative and/or postoperative drugs, medications, or supplementation related to orthognathic surgery.

RESULTS

This guide included 78 studies on various medications in orthognathic surgery. It encompasses clinical trials, cohort studies, cross-sectional studies, prospective and retrospective studies. The topics covered include antibiotics, analgesics, corticosteroids, antiemetics, hemostatic agents, local anesthetics, herbal medicine, and botulinum toxin. Pain and edema control involved specific medications, while local anesthesia utilized ropivacaine and bupivacaine. The guide also discusses mineral and vitamin supplementation. The effectiveness of hemostatic agents and antiemetics was highlighted.

CONCLUSION

Pain management, reduced swelling, enhanced wound healing, and faster recovery are among the advantages. In addition to the standard drugs and medications, the inclusion of vitamin and mineral supplements, tranexamic acid, postoperative anesthetic blocks, and preemptive antiemetics is anticipated to offer various benefits in orthognathic surgery, despite the limited available evidence.

Factors affecting progressive facial swelling immediately after orthognathic surgery: A retrospective cohort study

The aim of this study was to identify clinical factors associated with progressive facial swelling after orthognathic surgery. Patients diagnosed with jaw deformities and undergoing orthognathic surgery were retrospectively evaluated, and those with surgical site infection, Le Fort I osteotomy, or genioplasty only were excluded. Facial swelling volume was calculated by comparing facial volume preoperatively and three days postoperatively using 3D images and image analysis software (VECTRA H2). FXIII was measured within three days after surgery in only patients with unexplained postoperative bleeding or hematoma. The correlation between facial swelling volume and clinical factors was statistically analyzed. Facial swelling volume was examined in 78 patients. Univariate analysis showed a significant difference between facial swelling volume (mean = 41.6 cm3) and operation time (mean = 209.3 min, r = 0.283, p = 0.012), ΔHb level (mean = 1.18 g/dL, r = 0.235, p = 0.039), as well as decreased factor XIII activity (mean = 75.3%, p = 0.012). Multivariate analysis showed a significant difference between facial swelling volume and FXIII deficiency (standard error = 6.44, p = 0.031).Progressive facial swelling immediately after orthognathic surgery may be due to factor XIII deficiency.

Ambulatory sagittal split ramus osteotomy: strategy for enhanced recovery after surgery

The sagittal split ramus osteotomy (SSRO) has been performed mainly on an inpatient basis because of the duration of anaesthesia and the potential risk of postoperative complications, such as bleeding, pain, nausea, and vomiting. However, advances in both surgical and anaesthetic management have enabled the reduction of these risks and shortened the length of hospital stay. Thus, the SSRO may be feasible even in the ambulatory setting in elective cases. The clinical records of all patients who underwent an outpatient SSRO between August 2011 and September 2020 at Lilla Craniofacial Clinic were reviewed retrospectively. Data on age, sex, duration of surgery, operative procedures, intraoperative bleeding, and admission status were investigated. In total, 143 patients underwent a bilateral SSRO. The SSRO was performed as an isolated procedure in 73 patients and concomitantly with other surgical procedures in the remaining 70 patients. Overall, 142 of the 143 patients were discharged on the day of surgery (99.3%); only one (0.7%) required an overnight stay because of a submental haemorrhage after genioplasty. No emergency hospitalizations or readmissions occurred after discharge. Multimodal perioperative management, both surgical and anaesthetic, facilitated enhanced patient recovery after surgery, and SSRO was performed successfully and safely as an ambulatory procedure.

Effectiveness of Physical Therapy in Orthognathic Surgery Patients: A Systematic Review of Randomized Controlled Trials

Orthognathic surgery (OS) can present many complications that affect patients' rehabilitation. However, there have been no systematic reviews that assessed the effectiveness of physiotherapy interventions in the postsurgical rehabilitation of OS patients. The aim of this systematic review was to analyze the effectiveness of physiotherapy after OS. The inclusion criteria were randomized clinical trials (RCTs) of patients who underwent OS and who received therapeutic interventions that included any physiotherapy modality. Temporomandibular joint disorders were excluded. After the filtering process, five RCTs were selected from the 1152 initially obtained (two had acceptable methodological quality; three had insufficient methodological quality). The results obtained showed that the effects of the physiotherapy interventions studied in this systematic review on the variables of range of motion, pain, edema and masticatory muscle strength were limited. Only laser therapy and LED showed a moderate level of evidence in the postoperative neurosensory rehabilitation of the inferior alveolar nerve compared with a placebo LED intervention.
