Corticosteroid administration in oral and orthognathic surgery: a systematic review of the literature and meta-analysis

Intraoperative dexamethasone and chronic postsurgical pain: a propensity score-matched analysis of a large trial

BACKGROUND

Dexamethasone has been shown to reduce acute pain after surgery, but there is uncertainty as to its effects on chronic postsurgical pain (CPSP). We hypothesised that in patients undergoing major noncardiac surgery, a single intraoperative dose of dexamethasone increases the incidence of CPSP.

METHODS

We devised a propensity score-matched analysis of the ENIGMA-II trial CPSP dataset, aiming to compare the incidence of CPSP in patients who had received dexamethasone or not 12 months after major noncardiac surgery. The primary outcome was the incidence of CPSP. We used propensity score matching and inverse probability weighting to balance baseline variables to estimate the average marginal effect of dexamethasone on patient outcomes, accounting for confounding to estimate the average treatment effect on those treated with dexamethasone.

RESULTS

We analysed 2999 patients, of whom 116 of 973 (11.9%) receiving dexamethasone reported CPSP, and 380 of 2026 (18.8%) not receiving dexamethasone reported CPSP, unadjusted odds ratio 0.76 (95% confidence interval 0.78-1.00), P=0.052. After propensity score matching, CPSP occurred in 116 of 973 patients (12.2%) receiving dexamethasone and 380 of 2026 patients (13.8%) not receiving dexamethasone, adjusted risk ratio 0.88 (95% confidence interval 0.61-1.27), P=0.493. There was no difference between groups in quality of life or pain interference with daily activities, but 'least pain' (P=0.033) and 'pain right now' (P=0.034) were higher in the dexamethasone group.

CONCLUSIONS

Dexamethasone does not increase the risk of chronic postsurgical pain after major noncardiac surgery.

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.

Three-dimensional imaging evaluation of facial swelling after orthognathic surgery with compression and Kinesio taping therapy: a randomized clinical trial

Background

Postoperative swelling is a common complication of orthognathic surgery. The authors used three-dimensional (3D) image analysis and body surface temperature to determine the effects of compression taping (CT) and Kinesio taping (KT) by the epidermis, dermis, and fascia method (EDF-KT) on postoperative swelling.

Materials and methods

The authors conducted a prospective, parallel-group, randomized controlled trial. Among the 162 patients diagnosed with jaw deformity and who underwent orthognathic surgery from August 2020 to October 2022, 105 patients (men: 36, women: 69, mean age: 28.27±8.92) underwent Le Fort type I + sagittal split ramus osteotomy (SSRO) or SSRO and were included in this study. Patients were randomly divided into three groups: EDF-KT group (n=31), CT group (n=41), and no tape group (control group, n=30). All taping was performed immediately postoperatively and removed on postoperative day (POD) 5. Three-dimensional images of the participants' faces were obtained preoperatively and at PODs 3, 7, 30, and 90 using a hand-held 3D imaging system and infrared thermography.

Results

No significant difference was observed in postoperative swelling and postoperative body surface temperature between the groups at each time point. The CT group showed a trend towards reduced swelling on PODs 3 and 7 and a trend toward residual swelling on POD 90. The EDF-KT group showed a trend towards an increase in postoperative body surface temperature.

Conclusion

CT taping may not be appropriate for postoperative swelling control, suggesting that EDF-KT may affect body surface temperature. Further validation of the efficacy of KT for jaw deformities is needed.

Effectiveness of Elastic Therapeutic Tape in Reducing Edema, Pain and Trismus following Surgery for Facial Fractures: A Systematic Review and Meta-Analysis

Facial fractures cause postoperative morbidity, including edema, pain, and trismus. Elastic therapeutic tapes are used for optimizing recovery. Background: The aim of the present systematic review and meta-analysis was to evaluate the effectiveness of elastic tape Kinesio taping (KT) in reducing postoperative morbidity in facial fractures surgeries. Methods: A systematic review was conducted in accordance with the PRISMA guidelines. Searches were conducted in the Cochrane, Medline, Scopus, Embase and Web of Science databases using a pre-established search strategy. Results: A total of 811 studies were retrieved after the duplicates were removed, and only randomized clinical trials were included. Eight trials, involving 319 participants, were deemed eligible. One study solely investigated the effect on edema, while the others analyzed at least two of the variables of interest. Results from two RCTs, where qualitative analysis was applicable, suggest a potential reduction in edema in the KT group compared to the control group on the second (RR -0.55, 95% CI -0.89 to -0.22; p = 0.01; I2 = 0%) and third postoperative days (RR -0.71, 95% CI -1.01 to -0.40; p < 0.00001; I2 = 0%). Conclusions: KT is effective in controlling postoperative edema following surgery for facial fractures. However, the effects on pain and trismus should be explored further in studies with standardized methods.

The Effect of Steroid and Mannitol Combination Treatment on Postoperative Rehabilitation of Multiple Metacarpal Bone Fractures

Background and Objectives: The expedient resolution of postoperative soft tissue edema is particularly important in hand surgery. Prolonged edema and pain become an obstacle to postoperative rehabilitation, delay return to daily life, and in severe cases, lead to a permanent decrease in range of motion. Based on the common physiology between postoperative hand swelling and complex regional pain syndrome (CRPS), we sought to determine if postoperative mannitol and steroid administration to multiple metacarpal bone fracture patients effectively reduces hand swelling and pain and is beneficial for hand rehabilitation. Materials and Methods: From March 2015 to February 2019, 21 patients who received closed pinning for multiple metacarpal fractures were included in a retrospective cohort study. The control group (n = 11) underwent a routine recovery, while the treatment group (n = 10) received dexamethasone and mannitol injections for five days postoperatively. Serial changes in the degree of pain and fingertip-to-palm distance (FPD) were measured in both groups. The duration from surgery to the initiation of rehabilitation and time to full grip was also compared. Results: Compared to the control, the treatment group showed a faster alleviation of pain scores from the postoperative fifth day (2.91 versus 1.80, p = 0.013), and faster recovery of FPD from postoperative two weeks (3.27 versus 1.90, p = 0.002). Time to physical therapy initiation (6.73 versus 3.80 days, p = 0.002) and full grip achievement (42.46 versus 32.70 days, p = 0.002) were also faster in the treatment group. Conclusions: The steroid-mannitol combination treatment for multiple metacarpal bone fracture patients in the acute postoperative phase promoted the reduction of hand edema and pain, leading to the earlier initiation of physical therapy, rapid improvement in joint motion, and faster achievement of full grip.

Perioperative therapies to reduce edema after orthognathic surgery: a systematic review and meta-analysis

Objective To systematically review the literature and assess the effectiveness of perioperative systemic and nonsystemic therapies in reducing edema after orthognathic surgery. Study Design Four databases (PubMed, Web of Science, Bireme, and Scopus) were searched. Only randomized clinical trials were included and assessed using the RoB 2.0 software (Cochrane Collaboration, London, UK). Studies were grouped into time of assessment and systemic/nonsystemic therapy. Results Eighteen studies were included in this review (8 in the meta-analysis, n = 349). The qualitative assessment of systemic (enzyme therapy, dexamethasone, betamethasone, and Venoplant) and nonsystemic therapies (thermotherapy and K-Taping) appear to reduce edema. Manual lymphatic drainage (MLD) after 72 hours (CI: -1.03 to 2.31; P = .45), and 30 days (CI: -1.53 to 0.49; P = .49), and laser after 24 hours (CI: -1.36 to 1.48; P = .93), 72 hours (CI: -4.81 to 2.92; P = .63), 30 days (CI: -3.44 to 0.99; P = .28), and 90 days (CI: -1.83 to 0.96; P = .54) showed no significance. Thermotherapy reduced edema after 48 hours (CI: -48.47 to -13.31; P = .0006) and 30 days (CI: -14.73 to -1.98; P = .01). Conclusion The Grading of Recommendations, Assessment, Development and Evaluations tool showed moderate evidence for thermotherapy (significant reduction of edema), whereas the MLD and laser results were rated as high certainty of evidence (no reduction of edema).

The use of corticosteroids in the lateral sinus augmentation surgical procedure: A systematic review and meta-analysis

BACKGROUND

The lateral maxillary sinus augmentation (MSA) procedure has good predictability in terms of the success of bone regeneration with a low incidence of postoperative infections, estimated between 2% and 5.6%. Although the use of antibiotics is an established and standardized prophylactic measure for MSA procedures, the addition of corticosteroids still varies among clinician preference and clinical judgment.

PURPOSE

The aim of this systematic review was to identify whether the administration of corticosteroids during the MSA surgical procedure affects postoperative symptoms including swelling, pain, and infection rate.

MATERIALS AND METHODS

A literature search through PubMed, EMBASE, Ovid MEDLINE, and Web of Science indices, according to PICO criteria, was conducted to identify whether MSA peri-operative use of corticosteroids reduces the incidence of complications and patient morbidity. A single arm meta-analysis was performed due to the lack of randomized controlled trials (RCTs) comparing groups treated with or without peri-operative corticosteroids. The intracluster correlation co-efficient (ICC) and design effect were calculated to adjust for the clustering design.

RESULTS

In the 37 studies included, a total of 1599 patients (378 Cort, 1221 No-Cort) were analyzed. Before and after taking account of clustering, there was statistically significant effect of corticosteroids on swelling, pain, wound dehiscence, trismus, and hematoma. The complication rates postoperatively were comparable between the two study groups, however slight differences existed in the incidence of active suppuration (1.7% [95% CI 0.7-3.9] Cort vs. 3.2% [2.2-4.5] No-Cort), wound dehiscence (3.9% [1.3-11.2] Cort vs. 2.1% [1.0-4.1] No-Cort) and trismus (2.7% [0.8-8.4] Cort vs. 1.4% [0.8-2.5] No-Cort).

CONCLUSIONS

Although the event rate of the 1-to-2-week postoperative complications did not differ between the two groups, the lack of conclusive data and research comparing peri-operative corticosteroid use makes it impossible to draw definitive conclusions and more evidence and studies designed for this specific purpose are needed.

Association of menstrual cycle and postoperative quality of recovery in premenopausal women: a prospective cohort study

Background

Women have poorer quality of postoperative recovery from general anaesthesia than men. This persists for at least 3 days postoperatively, and is more pronounced in premenopausal women. Studies of menstrual cycle effects on pain or postoperative nausea and vomiting report conflicting results. Our aim was to determine whether menstrual cycle phase is associated with quality of recovery after surgery in premenopausal women.

Methods

Eligible women aged 18-45 yr undergoing wisdom teeth extraction or laparoscopic cholecystectomy under general anaesthesia with volatile agents were recruited from Epworth HealthCare Richmond in Melbourne, Australia from 2019 to 2021. Menstrual history and progesterone levels were used to determine cycle phase (luteal or non-luteal). Linear mixed and generalised linear regression models were fitted to examine differences in Quality of Recovery-15 (QoR-15) score on postoperative days 1 (primary outcome) and 3, and secondary outcomes (pain, analgesic effectiveness, postoperative nausea and vomiting, prolonged hospital admission), between groups, adjusting for confounders.

Results

A total of 177 women were recruited (74 luteal, 103 non-luteal). Six (3%) underwent laparoscopic cholecystectomy. Estimated mean differences (95% confidence interval; P-value) in adjusted QoR-15 scores between luteal and non-luteal groups were -0.05 (-5.86 to 5.76; P=0.986) and 1.40 (-4.41 to 7.21; P=0.636) on postoperative days 1 and 3, respectively. Secondary outcomes were not different between groups.

Conclusions

There was no significant difference in postoperative QoR-15 score or other outcomes between women in the luteal and non-luteal phases of their cycle. Women can be reassured that cycle phase does not impact postoperative quality of recovery when undergoing minor surgery under general anaesthesia.

Systematic mapping review of orthognathic surgery

STUDY DESIGN

Systematic mapping review AIM AND SCOPE: The objective of this mapping review was to identify, describe, and organize clinical research currently available from systematic reviews and primary studies regarding co-interventions and different surgical modalities used in orthognathic surgery (OS) and their outcomes.

METHODS

Systematic reviews (SRs), randomized controlled trials, and observational studies that evaluated perioperative OS co-interventions and surgical modalities were identified in an exhaustive search of MEDLINE, EMBASE, Epistemonikos, Lilacs, Web of Science, and CENTRAL. Grey literature was also screened.

RESULTS

Included were 35 SRs and 253 primary studies, 103 from SRs, and another 150 identified in our search. Overall, SR quality was rated as critically low, with only two SRs rated as of high quality. 19 questions on population, interventions, comparisons, and outcomes (PICO) extracted from the SRs focused on osteosynthesis methods, surgical cutting devices, and use of antibiotics, corticosteroids, and induced hypotension. Also identified were 15 research gaps. Evidence bubble maps were created to graphically depict the available evidence.

CONCLUSION

Future high-quality research, both primary and secondary, is needed to address the knowledge gaps identified in this systematic mapping review.

Efficacy of Methylprednisolone Compared to Other Drugs for Pain, Swelling, and Trismus Control after Third Molar Surgery: A Meta-Analysis

The purpose of this systematic review and meta-analysis was to assess the efficacy of methylprednisolone compared to other drugs to control postoperative complications following third molar surgery. PubMed and Google Scholar were used for article searching. Thereafter, the trials meeting the selection criteria and with high methodological quality, according to the Cochrane Collaboration’s risk of bias tool, were included in this study. The inverse variance test and mean difference using the Review Manager Software 5.3 for Windows were used to carry out data analysis. Qualitative analysis shows that methylprednisolone is more effective than NSAIDs, but inferior to dexamethasone, for controlling postoperative complications after third molar removal. The quantitative analysis showed no statistical difference for pain control, while trismus evaluation showed a statistical difference after 7 postoperative days in favor of methylprednisolone, when compared to other drugs. In conclusion, methylprednisolone was more effective for trismus control compared to other drugs after lower third molar surgery.

The Effect of Pre-Emptive Analgesia on the Postoperative Pain in Pediatric Otolaryngology: A Randomized, Controlled Trial

The aim of this randomized, controlled trial was to determine whether children undergoing otolaryngological procedures (adenoidectomy, adenotonsillotomy, or tonsillectomy) benefit from pre-emptive analgesia in the postoperative period. Methods: Fifty-five children were assessed for eligibility for the research. Four children refused to participate during the first stage of the study, leaving fifty-one (n = 51) to be randomly assigned either to receive pre-emptive analgesic acetaminophen (15 mg/kg; n = 26) or a placebo (n = 25) in addition to midazolam (0.5 mg/kg) as premedication. All children were anesthetized with sevoflurane, propofol (2−4 mg/kg), and fentanyl (2 mcg/kg). Postoperative pain was assessed using the Visual Analogue Scale (VAS), the Wong−Baker Faces Pain Rating Scale, and the Face, Legs, Activity, Cry, and Consolability (FLACC) scale. The postoperative pain was measured 1, 2, 4, and 6 h after the surgery. Results: The clinical trial reported a statistically significant correlation between administering pre-emptive analgesia (acetaminophen) and reducing pain in children after otolaryngological procedures compared to placebo. The ratio of boys to girls and age were similar among the groups (p > 0.05), so the groups of children were not divided by gender or age. Conclusions: Standard pre-emptive analgesia reduced the severity of pain in the postoperative period after otolaryngological procedures in children. Acetaminophen given before surgery reduces postoperative pain in children undergoing otolaryngological procedures.

Evolution of Hematological Parameters in Patients Undergoing Orthognathic Surgery With a View to Hospital Discharge: A Prospective Study

BACKGROUND

The length of hospital stays of patients undergoing orthognathic surgery depends on related local and systemic factors. Hematological changes resulting from orthognathic surgery, followed up in the postoperative period until hospital discharge, have neither yet been established for specific cases, nor for normal situations. This study aimed to describe the hemodynamic parameters of patients undergoing orthognathic surgery, considering a prediction of hospital discharge. A prospective analytical study was carried out on a sample of convenience for this purpose.

METHODS

The erythrogram, leukogram, and platelet count were assessed 24 and 72 hours after surgery and compared with preoperative values. Intraoperative volume loss was also assessed. Inferential statistical analyses were performed as analysis of variance or Friedman test, paired Wilcoxon test, Mann-Whitney test, and 2-tailed Spearman correlation.

RESULTS

The red blood cell count (mean ± standard deviation [median]); (4.60 ± 0.24 [4.56]), hemoglobin (12.82 ± 1.03 [12.75]), hematocrit (39.51 ± 3.47 [39.60]), and red cell distribution with (32.60 ± 0.88 [33.05]) were higher preoperatively (P < 0.001). Mean corpuscular volume (83.87 ± 5.63 [83.10]), mean corpuscular hemoglobin (27.50 ± 1.47 [28.00]), leukocytes (6262.00 ± 1448.36 [6380.00]). The volume loss varied between 463.87 and 752.13 mL (608.00 ± 144.13 [630.00]).

CONCLUSIONS

The results of the hematological evaluations corroborate the expectation of standard discharge from the hospital, with reflected changes resulting from volume loss and intense postoperative inflammatory response, even under the anti-inflammatory pharmacological effect.

Effect of Perioperative Systemic Dexamethasone on Pain, Edema, and Trismus in Mandibular Fracture Surgery: A Randomized Trial

ABSTRACT

The authors' aim was to evaluate the effect of perioperative systemic dexamethasone (DXM) administration on postoperative pain, edema, and trismus in mandibular fracture patients. The authors conducted a prospective randomized study of 45 patients with one or 2 noncomminuted fractures of the dentate part of the mandible. All patients underwent surgery for intraoral miniplate fixation. Patients in the study group were given a total of 30 mg DXM, while patients in the control group received neither DXM nor placebo. Only paracetamol and opioids were served as analgesics. Pain severity was assessed using the visual analog scale. The effect in facial swelling was measured in centimeters and analyzed as percentage change. Trismus was evaluated as the difference in maximal mouth opening by measuring interincisal distance in millimeters. The Mann-Whitney U test was applied to determine the statistical significance of differences between the groups. Thirty-four patients were included in the statistical analysis. The visual analog scale score was significantly lower in the study group than in the control group at 18 hours postoperatively (P = 0.033). Significant differences in edema or trismus were not found postoperatively between the DXM and control groups. In conclusion, perioperative DXM decreases postoperative pain in mandibular fracture patients when nonsteroidal anti-inflammatory drugs are not used, but it does not seem to be effective in reducing edema or trismus.

Postoperative Edema Resolution Post-Orthognathic Triple Jaw Surgery: A Three-Dimensional Volumetric Analysis

PURPOSE

The final result following orthognathic surgery may be hidden for months due to postoperative swelling. However, no substantial evidence supports this time estimate. Our study aims to three-dimensionally quantify volumetric changes in facial edema following triple-jaw surgery.

MATERIALS AND METHODS

This was a retrospective, three-dimensional (3D) study of patients who underwent primary orthognathic triple jaw surgery (Le Fort I, Bilateral Sagittal Split Osteotomy (BSSO), and osseous genioplasty) by the senior author (DMS). Vectra 3D Software (Canfield, Fairfield, NJ) was used to assess and quantify volumetric changes between serial 3D photos. An inverse line of best-fit was plotted to assess reduction in postoperative facial edema. The effects of gender, age, body mass index, and tranexamic acid administration on swelling resolution were analyzed through mixed linear model analysis.

RESULTS

A total of 46 patients (198 images) met the study criteria. The equation for the inverse function line of best fit was y = -13.14ln (x) + 39.54 (P < 0.01). On average, 60% of the swelling resolved in 1 month, 84% after 6 months, and nearly 93% after 12 months. There were no significant differences in the rate of swelling resolution when accounting for age, gender, body mass index, or tranexamic acid administration.

CONCLUSIONS

Most facial edema resolved during the first month following triple jaw surgery, with significant reduction in swelling between 6 and 12 months postoperatively. After 1 year, approximately 10% of the initial edema remained.

Cortisol in Oral and Maxillofacial Surgery: A Double-Edged Sword

Cortisol is a hormone that is naturally produced by the zona fasciculata of the cortex in the adrenal gland. One of its main functions is to decrease inflammation, particularly in areas where an inflammatory response is not necessary. In the field of oral and maxillofacial surgery, cortisol is used to improve the outcomes of surgical procedures and to make the postoperative period more comfortable for the patient. However, cortisol is considered a double-edged sword because its use is associated with both benefits and adverse effects. It is imperative to use cortisol following an accurate diagnosis, in addition to clarity regarding the desired surgical procedure for treating the acute or chronic condition affecting the patient. When used with caution, cortisol can serve as a valuable agent for reducing the postoperative inflammatory response in patients undergoing moderate as well as moderately severe surgical procedures.

Alternatives to opioids for acute pain management after dental procedures: A Department of Veterans Affairs consensus paper

BACKGROUND

Opioid misuse is a widespread public health problem, and opioids are often prescribed in the dental environment. These recommendations provide alternatives to opioids to reduce or eliminate dental procedure-related acute pain.

METHODS

A multidisciplinary working group developed these clinical recommendations to specifically address procedure-related acute pain. These recommendations, which are based on published peer-reviewed research and guidelines, include therapies used before, during, and after dental procedures. When evidence is not definitive, the best practices, which are based on experts' consensus, are included. The recommendations are not intended to be exhaustive.

RESULTS

These recommendations are a summary of the evidence and best practices for opioid alternatives to treat acute pain related to dental procedures.

CONCLUSIONS

Dental providers should prioritize opioid stewardship when managing procedure-related pain with strategies such as thorough preprocedure pain assessment, minimally invasive techniques, preemptive analgesia, intraprocedure pain management, and appropriately selected postprocedure pharmacologic therapy.

PRACTICAL IMPLICATIONS

These recommendations are a concise resource for clinical providers. It is important to address patients' procedure-related pain, using nonopioids whenever possible. Alternatives are outlined, allowing providers to make informed decisions.

Does the use of low-level light therapy postoperatively reduce pain, oedema, and neurosensory disorders following orthognathic surgery? A systematic review

The aim of this study was to evaluate the efficacy of low-level light therapy (LLLT) in improving pain, oedema, and neurosensory disorders of the inferior alveolar nerve (IAN) after orthognathic surgery. This systematic review was performed in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Searches were conducted in the PubMed, Embase, and Web of Science databases for randomized clinical trials (RCTs) published up to September 2020. After evaluating eligibility, 15 RCTs were selected. None of the studies reported an evaluation of all of the outcomes within the same publication. It was possible to determine the effect of LLLT in controlling pain following orthognathic surgery. Of the three studies evaluating this outcome, all observed a positive effect. Of the four studies that evaluated oedema, two found a positive effect. Of the 11 studies that evaluated neurosensory disorders of the IAN, all of them observed a positive effect, at least in one of the sensory evaluation tests. A meta-analysis was not possible due to the heterogeneity across studies. Considering the limitations of this review, but given the fact that LLLT is a minimally invasive intervention, its use merits consideration in immediate postoperative orthognathic surgery.

Orthognathic Surgery: A Bibliometric Analysis of the Top 100 Cited Articles

PURPOSE

An increasing number of articles on orthognathic surgery are published every year. This paper aims to provide a list of the top 100 cited articles on orthognathic surgery to help any professional level with interest in this topic and to map the trends of orthognathic surgery publications over time.

METHODS

A bibliographic search (retrospective study) following STROBE guidelines was performed on Google Scholar (GS) and Dimensions with the term "orthognathic surgery" in the title, abstract, and keywords. The number of citations, citations per year, authors, and publication year were evaluated. A ranking was created in GS citations order with the top 100 cited articles and variables discussed individually. A graphical illustration of keywords was created using VOSviewer. These steps are fundamental in creating this list and relating it to all published articles on the topic.

RESULTS

A helpful list of the top 100 articles was developed to help professionals in entirely different manners. Virtual planning and complications in orthognathic surgery were the most cited topics, with a 95% confidence interval (P < .05). Some curiosities are discussed, such as increasing interest in surgery first and the relation between airway/obstructive sleep apnea and orthognathic surgery.

CONCLUSIONS

Bibliometric and altmetric analysis for free using Google Scholar and Dimensions is laborious but possible. Bibliometrics is a powerful tool to become actualized at any health professional level, from students to academics; and could save considerable effort and time for parties interested in the topic. Appropriate keywords are a crucial step to wider article dissemination.

Do the Benefits of Systemic Corticosteroids Outweigh Adverse Effects During Maxillofacial Trauma Surgery? A Systematic Review and Meta-Analysis

PURPOSE

Perioperative systemic corticosteroids are widely used in maxillofacial trauma surgery to prevent postoperative complications, but potentially perceived benefits are speculative rather than evidence-based. The purpose of our systematic review and meta-analysis was to assess the effects of perioperative systemic corticosteroids on clinically significant outcomes in patients undergoing maxillofacial trauma surgery.

METHODS

We searched Medline, Embase, CENTRAL, Clinical trial registry, and grey literature as well as references of included trials. Our primary outcomes were facial edema and pain after the surgery. Our secondary outcomes were postoperative nausea and vomiting, neurosensory disturbance, functional recovery, wound infections, and other adverse events.

RESULTS

Of the 94 trials retrieved, 13 were included (n = 652). Perioperative steroid use was associated with reduced pain and facial edema. We observed a decrease in postoperative nausea and vomiting with the use of systemic corticosteroids (n = 184, OR = 0.53, [0.28, 1.02], I² = 0%). Four trials reported infections and impaired wound healing associated with steroids (n = 160. OR = 3.37, [1.43. 7.94], I² = 2%). The 13 trials had an unclear risk of bias.

CONCLUSIONS

Systemic corticosteroids reduced facial edema and postoperative pain, but impaired wound healing was also reported. The use of systemic steroids in maxillofacial trauma surgery is thus supported only by weak evidence and further research is advocated.

Index of Body Inflammation for Maxillofacial Surgery Purpose-to Make the Soluble Urokinase-Type Plasminogen Activator Receptor Serum Level Independent on Patient Age

Background: The serum suPAR level is affected in humans by it increases with age. Therefore it makes difficult interpretation and any comparison of age varied groups. The aim of this study is to find simple way to age independent presentation of suPAR serum level for maxillofacial surgery purpose. Methods: In generally healthy patients from 15 to 59 y.o. suPAR level was tested in serum before orthognathic or minor traumatologic procedures. Five ways to make the suPAR serum level assessment independent of age are proposed. Results: One way of making suPAR levels independent of age led to the result with the same statistical distribution as in the raw suPAR serum material and this distribution is the normal. Conclusion: The simple way for suPAR serum level analysis without its dependence on patient age is calculation of the index of body inflammation understood as square root of squared suPAR serum level divided by logarithm of patient age to base 10.

The "Safe Index" Considering Body Surface Area for Prolonged Dexamethasone Regimen in Airway Control After Head and Neck Microsurgical Reconstruction

BACKGROUND

Dexamethasone (Dexa) is frequently administrated to patients receiving head and neck microsurgical reconstruction with nasotracheal intubation postoperatively for airway control. Infection is the greatest concern when prolonging the treatment course. We aimed to find out the relationship between flap infection and the safe dose of Dexa.

MATERIALS AND METHODS

A retrospective review of enrolling total 156 patients underwent microsurgical free flap reconstruction for head and neck cancers with nasotracheal intubation from December 2015 to December 2016 was conducted. Among them, 139 patients had received prolonged Dexa treatment course (>2 days). Safe index was then defined as the total amount of used Dexa (in milligrams) over body weight (in kilograms), body mass index (in kilograms per square meter) and body surface area (BSA, in square meter). Statistics were performed for the cutoff level of the safe index and to find out the independent risk factors.

RESULTS

The cutoff level of the safe index was 0.76 for body weight group, 2.28 (10-3 m2) for body mass index group, and 33.84 mg/m2 for BSA group. Safe index for BSA group also outweighed other risk factors in multivariant analysis (odds ratio = 6.242, 95% confidence interval = 2.292-17.002, P = 0.000), which is the only independent risk factors for flap infection in our cohort.

CONCLUSIONS

Throughout our study, the "safe index" helps clinician easily predict flap infection risk when using Dexa as the medication for airway control after head and neck microsurgical reconstruction.

Effectiveness of dexamethasone injection in the pterygomandibular space before and after lower third molar surgery

Background

Previous studies have investigated the effects of dexamethasone injections into the pterygomandibular space and compared them to those of controls; however, the effects of dexamethasone injections before and after lower third molar surgery on postoperative complications have not been studied. This research investigated the postoperative sequelae of dexamethasone injections before and after surgery into the pterygomandibular space. The aim of this study was to evaluate the effects of preoperative and postoperative injections of 4 mg of dexamethasone into the pterygomandibular space on postoperative pain, facial swelling, and the restriction of mouth opening following lower third molar surgical removal.

Methods

Twenty-seven participants with bilateral symmetrical lower impacted third molars were included in this study. Each participant was randomly allocated to one of two groups. Group A received injections of 1 ml dexamethasone (4 mg/mL) and 1 mL placebo into the pterygomandibular space before and after surgery, respectively. Group B received the same doses of placebo before surgery and dexamethasone after surgery.

Results

A significant restriction of mouth opening on the second postoperative day was observed in both groups. Nonetheless, the postoperative restriction of mouth opening, facial swelling, postoperative pain, and analgesic consumption after lower third molar surgical removal were not significantly different in the two groups.

Conclusions

Regardless of the time of administration, dexamethasone injections into the pterygomandibular space resulted in satisfactory control of the postoperative sequelae of the mandibular third molar surgical removal.

Third Molar Surgery Outcomes: A Randomized Clinical Trial Comparing Submucosal and Intravenous Dexamethasone

OBJECTIVE

Swelling, pain, and trismus after third molar surgery have a negative impact on patients' quality-of-life in the days following surgery. The study aims to compare the efficacy of submucosal (SM) dexamethasone and intravenous (IV) dexamethasone in reducing these outcomes.

METHODS

The single-center study was designed as a randomized, controlled, double-blinded trial with a total of 130 participants evenly allocated into 2 treatment groups. All participants underwent the surgical removal of at least 2 mandibular third molars under intravenous sedation. The outcome variables studied were swelling, pain, and maximum incisal distances. The swelling was measured using a 3-dimensional camera (3dMD Inc, Atlanta, GA). The pain was quantified using a 100 mm visual analog scale (VAS). Maximum incisal distances were measured using a caliper. Participants completed the short-form Oral Health Impact Profile (OHIP-14). The 2 groups were compared using cross-tabulations and chi-square tests for categorical variables and analysis of variance for continuous variables.

RESULTS

The participants had a mean age of 22.6 years, 56.8% females and 12.4% smokers. There were no statistically significant differences in the distribution of study variables between the 2 groups. On day 2, mean facial swelling measurements were 7.3 cm³ in the IV group and 7.8 cm³ in the SM group (P > .05). The mean pain score was 31 in the IV group and 33 in the SM group (P > .05). The mean maximum incisal distances were 33.7 mm in the IV group and 34.5 mm in the SM group (P > .05). Both groups experienced poorer quality-of-life relative to baseline scores and were affected to a similar extent.

CONCLUSIONS

There are no differences in swelling, pain, and trismus between submucosal and intravenous dexamethasone in third molar surgery. Submucosal dexamethasone is a straightforward and accessible route of steroid administration in patients having third molar surgery under local anesthesia only.

Maxillary sinus haziness and facial swelling following suction drainage in the maxilla after orthognathic surgery

Background

We investigated the efficacy of a maxillary Jackson-Pratt (J-P) suction drain for preventing maxillary sinus hematoma and facial swelling after maxillary Le Fort I osteotomy (LF1).

Methods

We retrospectively evaluated 66 patients who underwent LF1 at a single institution. Of these, 41 had a J-P suction tube inserted in the mandible and maxilla (maxillary insertion), and 25 had a J-P drain inserted in the mandible only (no maxillary insertion). Facial CT was obtained before and 4 days after surgery. We compared mean midfacial swelling and maxillary sinus haziness by t test and examined correlations between bleeding amount and body mass index (BMI).

Results

For the maxillary-insertion group, the ratio of total maxillary sinus volume to haziness (57.5 ± 24.2%) was significantly lower than in the group without maxillary drain insertion (65.5% ± 20.3; P = .043). This latter group, however, did not have a significantly greater midfacial soft tissue volume (7575 mm³) than the maxillary-insertion group (7250 mm³; P = .728). BMI did not correlate significantly with bleeding amount or facial swelling.

Conclusions

Suction drainage in the maxilla reduced maxillary sinus haziness after orthognathic surgery but did not significantly reduce midfacial swelling.

Short-term Haematological Parameters Following Surgical Removal of Mandibular Third Molars with Different Doses of Methylprednisolone Compared with Placebo. A Randomized Controlled Trial

Objectives

To evaluate the influence of a single intraoperative injection of methylprednisolone on short-term haematological parameters following surgical removal of mandibular third molars.

Material and Methods

Fifty-two patients with indications for surgical removal of bilateral impacted mandibular third molars were included in a randomized, split-mouth and double-blinded study design. Each molar were randomly allocated into one of following four groups: 20 mg methylprednisolone, 30 mg methylprednisolone, 40 mg methylprednisolone and placebo. Peripheral blood samples were obtained before and three days after surgery. Haematological parameters involving haemoglobin, white blood cell count and C-reactive protein (CRP) were evaluated and expressed as mean changes. Level of significance was 0.05. Furthermore, outcomes were correlated for age, sex, smoking and time of surgery.

Results

There were no significant differences in postoperative haematological parameters with different doses of methylprednisolone compared with placebo. Peripheral blood samples revealed decreased level of haemoglobin and increased level of leucocytes and CRP in each group. Smokers displayed a significant lower level of haemoglobin and CRP compared with non-smokers (P < 0.05) and level of eosinophils decreased significantly with increasing age (P < 0.05).

Conclusions

This study indicates that a single intraoperative injection of methylprednisolone seems not to cause suppression of short-term haematological parameters compared with placebo following surgical removal of mandibular third molars.

Current Orthognathic Practice in India: Do We Need to Change?

The last decade or so has seen paradigm shifts in the various aspects of orthognathic surgery. A lot of these changes are to do with digitalization of the orthodontic-surgical workflow, optimization of surgery-first protocols, virtual surgical planning-based 3D printing solutions and changing patient-health-care dynamics. The aim of this article is to provide evidence-based recommendations that are both practical and economically viable for the current orthognathic practice in India.

Effects of different pre-operative doses of dexamethasone on alveolar repair in rats

Dexamethasone has been widly used in oral and maxillofacial surgery for controlling of postoperative surgical inflammation. Despite its clinical effectiveness, several studies have demonstrated the negative impact of this drug on the healing of soft and hard tissues. This study aimed to assess the effects of different pre-operative doses of dexamethasone on alveolar repair. Sixty rats were divided into four groups of 15 animals each. Single pre-operative doses of dexamethasone equivalent to human doses of 4 mg (Group 4 mg), 8 mg (Group 8 mg), and 12 mg (Group 12 mg), calculated by allometric dose extrapolation, were administered; and rats in the Control Group were injected with saline solution. The animals were anesthetized, and their left mandibular first molars (M1) were removed. After three, seven, and 40 days, 5 animals from each group were euthanized, and bone samples of M1 alveolus were collected for radipgraphic, histomorphological and histometric evaluation of the early and late phases of alveolar healing. At three days, Group 12 mg presented reduced radiographic density, percentage of collagen, and connective matrix compared with the Control Group. At 7 days, the percentage of bone was increased in the Control Group compared to Groups 8 mg and 12 mg (P < 0.05). It can be concluded that a single pre-operative dose of 12 mg of dexamethasone affected the early stages of alveolar repair in rats.

Effect of postoperative steroids on clinical outcomes and radiographic findings of horizontal alveolar ridge augmentation: A retrospective study

BACKGROUND

The purpose of the study was to investigate if the prescription of oral postoperative steroids has an effect on clinical outcomes of horizontal ridge augmentation including implant placement and characteristics of the grafted bone.

METHODS

A retrospective chart review of 73 horizontal ridge augmentation cases was completed to assess the clinical outcomes, 53 of those cases were further assessed radiographically. Information was gathered regarding surgical technique, grafting materials, postoperative healing, medications used postoperatively, bone growth, and density changes as quantified on a cone-beam computed tomography (CBCT) scan. Statistical analysis was completed to identify whether the use of postoperative oral steroids altered outcomes.

RESULTS

Steroids were used postoperatively following various horizontal ridge augmentation procedures. The use of tenting screws and resorbable membranes with a combination of osseous allograft and xenograft was used in 73 cases, 53 of which had preoperative and postoperative CBCT scans. Graft exposure occurred in five of the cases (9%), with the majority (n = 4) among those with postoperative steroids, but this was not statistically significant (P-value = 0.6510). Use of steroids was also not significantly associated with the number of courses of antibiotics (P-value > 0.05), but it was significantly associated with increased number of postoperative visits (P-value < 0.05). Among the subset for radiographic analysis (n = 53), there were significant clinical and radiographic dimensional changes in alveolar ridge width with an average horizontal bone gain of 3.6 mm. There were no statistically significant differences found in radiographic linear bone gain or clinical outcomes with the addition of steroids. A marginally statistically significant in the density of grafted bone was found with the addition of steroids (P-value > 0.05).

CONCLUSION

The prescription of postoperative steroids did not make a significant difference in clinical outcomes, success of implant placement or on radiographic assessment of grafted sites following horizontal alveolar ridge augmentation.

Evaluation of the impact of preoperative use of dexamethasone and cyclobenzaprine in surgical extraction of lower third molars on trismus by electromyographic analysis

PURPOSE

The aim of this study was to evaluate the influence of cyclobenzaprine and dexamethasone on ​the electrical activity of the masticatory muscles in patients who had undergone lower third molar surgery.

METHODS

Thirty bilateral impacted lower third molars with indication of extraction were randomised into three groups: the control group, the dexamethasone, and the cyclobenzaprine group. To obtain muscular electrical activity and mouth opening, an electromyographic device was used at mandibular rest and maximum voluntary contraction and compared pre- and post-operatively.

RESULTS

During muscle contraction, no significant difference was observed in the electromyographic records on the non-operated side. On the operated side, there was a reduction in electrical activity for both drugs pre-operatively and immediately post-operatively compared to the control group. All pharmacological agents promoted a higher mouth opening compared to control group.

CONCLUSION

The results suggest that dexamethasone and cyclobenzaprine may be useful as an adjuvant in the prevention of motor dysfunctions in third molar surgery.

Three-Dimensional Evaluation of the Effects of Kinesio Taping on Postoperative Swelling and Pain after Surgically Assisted Rapid Palatal Expansion

Objectives

The purpose of the present study was to evaluate the effects of kinesio taping on pain and swelling after surgically assisted rapid palatal expansion.

Material and Methods

A total of 21 (12 male and 9 female) patients with transverse maxillary deficiency were enrolled in the study. Kinesio taping (KT) was applied unilaterally in each patient, whereby sides of the face with KT application were included into the (a) KT group and the other sides were included into the (b) non-KT group. Changes in facial volume were evaluated on digital images using the 3dMD Face System. Pain scores were assessed at postoperative days 1, 2, 3, 4, 5, 6, and 7 using the visual analog scale (VAS). Two-way repeated measures analysis of variance and Mann Whitney U test were used for statistical analyses.

Results

Swelling was significantly lower in the KT group compared to the non-KT group from T0 to T1 (36.42 [SD 19.71] mm³ vs. 183.84 [SD 49.33] mm³) and was significantly greater in the non-KT group compared to the KT group from T0 to T2 (70.88 [SD 15.73] mm³ vs. 21.46 [SD 13.39] mm³) (P < 0.001 for both). The VAS scores were significantly lower in the KT group compared to the non-KT group at all time points (P < 0.05).

Conclusions

The application of kinesio taping after maxillofacial surgery reduced the pain and swelling in the postoperative period. Kinesio taping can be used as an alternative to other methods that are used for the reduction of postoperative complaints.

Management of postoperative pain in maxillofacial surgery

In this review we describe the evidence base for postoperative analgesia after maxillofacial surgery. We discuss the implications of poorly managed pain, risk factors for the development of severe pain, and pharmacological and non-pharmacological analgesic strategies to manage it.

Day-case bilateral sagittal split osteotomy

In the UK, patients who have bilateral sagittal split osteotomy (BSSO) have generally been thought to require inpatient admission and an overnight hospital stay. However, since the introduction of national standards on day case surgery in the UK in 2011, patients at the Royal Gwent Hospital, Newport, have been treated as day cases, and have been pleased with the results. The aim of this paper was to show that these procedures conform to current national standards, and can be done successfully and safely. We retrospectively reviewed all patients who had isolated BSSO planned as day cases between March 2015 and February 2017. Thirty-four were eligible. Of them, 32 were discharged on the day of operation and two were admitted postoperatively: one because of severe nausea and vomiting and the other because of bleeding. No patients were readmitted within 48hours of the procedure. BSSO can be done successfully and routinely as a day-case procedure. However, to reduce the rate of unplanned admissions, we recommended that operations start early in the morning.

Intraoperative dexamethasone does not increase the risk of postoperative wound infection: a propensity score-matched post hoc analysis of the ENIGMA-II trial (EnDEX)

BACKGROUND

In a post hoc analysis of the ENIGMA-II trial, we sought to determine whether intraoperative dexamethasone was associated with adverse safety outcomes.

METHODS

Inverse probability weighting with estimated propensity scores was used to determine the association of dexamethasone administration with postoperative infection, quality of recovery, and adverse safety outcomes for 5499 of the 7112 non-cardiac surgery subjects enrolled in ENIGMA-II.

RESULTS

Dexamethasone was administered to 2178 (40%) of the 5499 subjects included in this analysis and was not associated with wound infection [189 (8.7%) vs 275 (8.3%); propensity score-adjusted relative risk (RR) 1.10; 95% confidence interval (CI) 0.89-1.34; P=0.38], severe postoperative nausea and vomiting on day 1 [242 (7.3%) vs 189 (8.7%); propensity score-adjusted RR 1.06; 95% CI 0.86-1.30; P=0.59], quality of recovery score [median 14, interquartile range (IQR) 12-15, vs median 14, IQR 12-16, P=0.10), length of stay in the postanaesthesia care unit [propensity score-adjusted median (IQR) 2.0 (1.3, 2.9) vs 1.9 (1.3, 3.1), P=0.60], or the primary outcome of the main trial. Dexamethasone administration was associated with a decrease in fever on days 1-3 [182 (8.4%) vs 488 (14.7%); RR 0.61; 95% CI 0.5-0.74; P<0.001] and shorter lengths of stay in hospital [propensity score-adjusted median (IQR) 5.0 (2.9, 8.2) vs 5.3 (3.1, 9.1), P<0.001]. Neither diabetes mellitus nor surgical wound contamination status altered these outcomes.

CONCLUSION

Dexamethasone administration to high-risk non-cardiac surgical patients did not increase the risk of postoperative wound infection or other adverse events up to day 30, and appears to be safe in patients either with or without diabetes mellitus.

Effect of paracetamol/prednisolone versus paracetamol/ibuprofen on post-operative recovery after adult tonsillectomy

OBJECTIVE

To compare the effect of Paracetamol/Prednisolone versus Paracetamol/Ibuprofen on post-operative recovery after adult tonsillectomy.

BACKGROUND

Various analgesic protocols have been proposed for the control of post-tonsillectomy morbidity with need for better control in adult population for having higher severity of post-operative pain and risk of secondary post-tonsillectomy bleeding.

METHODS

This is a prospective cohort study conducted on 248 patients with age of 12 years or older distributed as two equal groups; the first one receiving Paracetamol/Prednisolone and the second one receiving Paracetamol/Ibuprofen. Both groups were compared at 7 days post-operative regarding pain at rest, tiredness of speech, dietary intake, and decrease in sleep duration. Both groups were compared regarding incidence of nausea and vomiting at 2 days post-operative. The incidence and severity of secondary post-tonsillectomy hemorrhage was compared between the two groups.

RESULTS

Pain at rest (no swallowing - no talking) was less in group I but not reaching statistical significance (p = 0.36). In addition, dietary intake was better in group I but not reaching statistical significance (P = 0.17). However, talking ability was better with statistically significant difference (P = 0.03) in group I. Impairment of sleep was less with group II but not reaching statistical significance (p = 0.31). The incidence of vomiting at second post-operative day was less in group I with statistical significance (p = 0.049). The incidence of secondary post-tonsillectomy bleeding was significantly higher in group II with statistical significance (p = 0.046). The severity of bleeding episodes was also significantly higher in group II (p = 0.045).

CONCLUSION

Both ibuprofen and prednisolone were effective as a part of post-operative medication regimen after adult tonsillectomy. However, prednisolone was superior to ibuprofen regarding improvement of pain at rest, dietary intake, tiredness of speech and post-operative nausea and vomiting. However, ibuprofen had a better impact on sleep. The incidence and severity of secondary post-tonsillectomy hemorrhage were significantly higher with ibuprofen favoring the selection of prednisolone to be combined with paracetamol in the post-operative medication protocol following tonsillectomy.

Different Dosages of Corticosteroid and Routes of Administration in Mandibular Third Molar Surgery: a Systematic Review

Objectives

The objective of the present systematic review was to test the hypothesis of no difference in facial swelling, pain and trismus after surgical removal of mandibular third molar with different dosages of corticosteroids and administration routes.

Material and Methods

A MEDLINE (PubMed), Embase database and Cochrane Library search in combination with a hand-search of relevant journals was conducted by including randomized controlled trials published in English until 1^st December 2017.

Results

Seven studies fulfilled the inclusion criteria. Considerable variation in the included studies prevented meta-analysis from being performed. Preoperative submucosal injection of corticosteroids significantly diminishes facial swelling, pain and trismus compared with placebo. However, different dosages of corticosteroid and administration routes reveal contrary results indicating that administration of a higher dosage of corticosteroids do not necessarily cause a further decrease in facial swelling, pain and trismus.

Conclusions

Consequently, the optimal dosage of corticosteroids and administration route for diminishing postsurgical morbidity and improve quality of life after surgical removal of mandibular third molar is presently unknown. Therefore, further well-designed randomized clinical trials including a standardised protocol, patient-reported outcome measures and three-dimensional analysis of facial swelling is needed.

The Impact of the Use of Kinesio Taping Method on the Reduction of Swelling in Patients After Orthognathic Surgery: A Pilot Study

BACKGROUND Orthognathic surgery (OGS) is associated with extensive surgical intervention within the soft and hard tissues of the facial region of the skull leading to inflammatory reactions. The presence of postoperative swelling indicates the accumulation of exudate or transudate; both these fluids occur in surgery. Massive swelling is a significant problem, because the tension of tissues intensifies pain sensations. The aim of the study was to evaluate the effectiveness of the kinesio taping method (KT) in patients after orthognathic surgery in the area of the facial skull in terms of eliminating postoperative swelling. MATERIAL AND METHODS The study of the impact of kinesiology tape applied after orthognathic surgery to the craniofacial area on the elimination of swelling was performed in sixteen patients who suffered from this complication after bilateral sagittal split osteotomy. RESULTS The swelling was shown to be reduced after KT; within the same study the differences were statistically significant between the left and right sides and for the same side (p<0.05). The application of the lymphatic kinesio taping method led to the reduction of tension in the affected area and restoration of proper lymphatic circulation in the region covered by swelling. This allows for the improvement of the blood and lymph microcirculation and activation of self-healing processes. CONCLUSIONS The analysis of the impact of the practical use of the lymphatic KT on complications after orthognathic surgery revealed that it had a beneficial effect on the reduction of swelling. The use of the KT method seems promising because it is simple to carry out, not traumatic, economical and rarely causes undesirable allergies.

More Harm Than Benefit of Perioperative Dexamethasone on Recovery Following Reconstructive Head and Neck Cancer Surgery: A Prospective Double-Blind Randomized Trial

PURPOSE

Prospective studies on the effect of dexamethasone after microvascular reconstructive head and neck surgery are sparse despite the widespread use of dexamethasone in this setting. The aim of this study was to clarify whether perioperative use of dexamethasone would improve the quality and speed of recovery. The authors hypothesized that dexamethasone would enhance recovery and diminish pain and nausea.

MATERIALS AND METHODS

Ninety-three patients with oropharyngeal cancer and microvascular reconstruction were included in this prospective double-blinded randomized controlled trial. Patients in the study group (n = 51) received dexamethasone 60 mg over 3 perioperative days; 42 patients did not receive dexamethasone and served as controls. Patient rehabilitation, postoperative opioid and insulin consumption, postoperative nausea and vomiting (PONV), and C-reactive protein (CRP), leukocyte, and lactate levels were recorded.

RESULTS

There was significantly less pain in the study group (P = .030) and the total oxycodone dose for 5 days postoperatively was lower (P = .040). Dexamethasone did not significantly lessen PONV for 5 days postoperatively (P > .05). There were no differences between groups in intensive care unit or hospital stay or in other clinical measures of recovery. Patients receiving dexamethasone required significantly more insulin compared with patients in the control group (P < .001). Lactate and leukocyte levels were significantly higher (P < .001) and CRP levels were significantly lower in the study group.

CONCLUSION

The only benefit of perioperative dexamethasone use was lower total oxycodone dose; however, the disadvantages were greater. Because dexamethasone can have adverse effects on the postoperative course, routine use of dexamethasone as a pain or nausea medication during reconstructive head and neck cancer surgery is not recommended.

Behavior of C-reactive protein in association with surgery of facial fracture and the influence of dexamethasone

PURPOSE

To clarify pre- and postoperative C-reactive protein (CRP) levels in patients with facial fractures and to investigate the influence of perioperatively administered dexamethasone on postoperative CRP levels.

PATIENTS AND METHODS

Facial fracture patients were randomized to receive perioperatively a total dose of 30 mg of dexamethasone (Oradexon®), whereas patients in the control group received no glucocorticoid. The analysis included patients who had CRP measured pre- and postoperatively.

RESULTS

A total of 73 adult patients with facial fractures were included in the final analysis. Mean CRP level was elevated preoperatively and the level increased further after surgery. However, postoperative CRP rise was significantly impeded by dexamethasone (p < 0.001), regardless of gender, age, treatment delay, site of fracture, surgical approach, and duration of surgery. CRP rise halved on the 1st postoperative day when dexamethasone was used. In addition, dexamethasone resulted in a CRP decrease on the 2nd postoperative day, whereas the CRP rise continued in the control group.

CONCLUSIONS

CRP rise is a normal body response after facial fracture and surgery that can be markedly reduced with dexamethasone. CRP changes should be considered with caution if perioperative dexamethasone is used.

Endodontic-related inferior alveolar nerve injuries: A review and a therapeutic flow chart

INTRODUCTION

Inferior alveolar nerve (IAN) lesions related to endodontic treatments can be explained by the anatomical proximity between the apices of the mandibular posterior teeth and the mandibular canal. The aim of this article is to review the management of inferior alveolar nerve lesions due to endodontic treatments and to establish a therapeutic flow chart.

METHODS

A review of publications reporting IAN damage related to endodontic treatment over the past 20 years has been conducted, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist; it combines an electronic search of the Pubmed^® and Google Scholar^® databasis. Forty-two full-text articles corresponding to 115 clinical cases have been selected. Two personal clinical cases were additionally reported.

RESULTS

IAN lesions due to endodontic treatments require urgent management. Early surgical removal of the excess of endodontic material, in contact with the nerve allows the best recovery prognosis (72h). Beyond this delay, irreversible nervous lesions prevail and a medical symptomatic treatment, most of the time with pregabalin, must be/can be carried out. A delayed surgical procedure shows some good benefits for patients. However, the healing prognosis remains poorly predictable.

Oral Health-Related Quality of Life Following Third Molar Surgery in an African Population

Introduction:

Surgical extraction of impacted mandibular third molars is often associated with sequelae such as postoperative pain, facial edema, and limitation in mouth opening ability. These sequelae may result in changes in the patients’ lifestyle and quality of life (QoL).

Aim:

The aim of this study was to evaluate the effect of surgical extraction of impacted mandibular third molars on patients’ QoL in the immediate postoperative period (7 days).

Materials and Methods:

Ethical approval for this study was obtained from the Health Research and Ethics committee of the Lagos University Teaching Hospital. A total of 124 individuals with impacted mandibular third molars, who satisfied the inclusion criteria and consented to participate in this study, were included. The Oral Health Impact Profile-14 (OHIP-14) QoL questionnaire was used to assess QoL. QoL was assessed preoperatively (baseline) and on postoperative days (PODs) 1, 3, and 7. Maximal interincisal mouth opening, facial width, and pain were also reviewed at all evaluation points. Data analysis was done using the Statistical Package for Social Sciences (SPSS) for Windows (version 16.0, Chicago, IL, USA).

Results:

A total of 124 individuals were included in the final analysis. An age range of 18–51 years with a mean (±standard deviation) of 28.5 (7.4) years was observed. A male to female ratio of 1:1.5 was observed. The most frequently encountered type of impaction was the mesioangular impaction 51 (41.1%) and recurrent pericoronitis was the principal reason for extraction 53 (42.7%). The severity of the sequelae (pain, trismus, and facial edema) was maximal on the first POD. Patients’ overall QoL deteriorated sharply on the first POD and subsequently improved.

Conclusion:

Surgical extraction of mandibular third molars is associated with worsening of patients’ postoperative QoL in the immediate postoperative period. Prospective patients should be informed about this, and ways of reducing this untoward effect should be explored.

Treatment modalities and risk factors associated with refractory neurosensory disturbances of the inferior alveolar nerve following oral surgery: a multicentre retrospective study

Little research has been conducted into hypoesthesia, and no studies have elucidated the risk factors for refractory hypoesthesia and compared treatment modalities. The purpose of this multicentre retrospective cohort study was to investigate the relationships between various risk factors, treatment modalities, and refractory hypoesthesia. Risk factors for refractory hypoesthesia after oral surgery were evaluated using univariate and multivariate analysis. To minimize the selection bias associated with a retrospective data analysis, a propensity score analysis was performed between the medication and non-medication groups (65 sites in each group). Moderate or severe hypoesthesia (odds ratio 13.42) and no or late administration of ATP/vitamin B12 (odds ratio 2.28) were significantly associated with refractory hypoesthesia. In the propensity score analysis, the incidence rate of refractory hypoesthesia in the medication group was lower than that in the non-medication group (P<0.001). This study demonstrated the multivariate relationships between various risk factors, treatment modalities, and refractory hypoesthesia. Moderate or severe hypoesthesia and no or late administration of ATP/vitamin B12 were significantly associated with refractory hypoesthesia. Therefore, clinicians should consider these risk factors and initiate early oral administration of ATP/vitamin B12 in cases of hypoesthesia.

The influence of dexamethasone on postoperative swelling and neurosensory disturbances after orthognathic surgery: a randomized controlled clinical trial

BACKGROUND

Orthognathic surgery is associated with considerable swelling and neurosensory disturbances. Serious swelling can lead to great physical and psychological strain. A randomized, prospective, controlled clinical trial was realized in order to evaluate the effect of a preoperative intravenous dexamethasone injection of 40 mg on postoperative swelling and neurosensory disturbances after orthognathic surgery.

METHODS

Thirty-eight patients (27 male and 11 female) patients, all with the indication for an orthognathic surgery, were enrolled in this study (mean age: 27.63 years, range: 16-61 years) and randomly divided into two groups (study group/ control group). Both groups underwent either maxillary and/or mandibular osteotomies, resulting in three subgroups according to surgical technique (A: LeFort I osteotomy, B: bilateral sagittal split osteotomy (BSSO), C: bimaxillary osteotomy). The study group received a single preoperative intravenous injection of 40 mg dexamethasone. Facial edema was measured by 3D surface scans on the 1st, 2nd, 5th, 14th and 90th postoperative day. Furthermore, neurosensory disturbances on the 2nd, 5th, 14th and 90th postoperative day were investigated by thermal stimulation.

RESULTS

Facial edema after LeFort I osteotomy, BSSO and bimaxillary osteotomy showed a significant decrease in the study group compared to the control group (P = 0.048, P = 0.045, P < 0.001). The influence of dexamethasone on neurosensory disturbances was not significant for the inferior alveolar nerve (P = 0.746) or the infraorbital nerve (P = 0.465).

CONCLUSIONS

Patients undergoing orthognathic surgery should receive a preoperative injection of dexamethasone in order to control and reduce edema. However, there was no influence of dexamethasone on reduction of neurosensory disturbances.

Influence of Electroacupuncture and Laser-Acupuncture on Treating Paresthesia in Patients Submitted to Combined Orthognathic Surgery and Genioplasty

Objective: The goal of this research was to observe the influence of electroacupuncture (EA) and laser-acupuncture on the return of tactile/pain sensitivity in patients who underwent orthognathic surgery. Materials and Methods: Thirty volunteers subjected to orthognathic surgery were evaluated and randomly divided into 2 groups, in which 3 treatments were evaluated: control (n = 30) (G0, medication + placebo laser treatment) and 2 experimental treatments (n = 15) (G1, medication + EA) or G2 (medication + laser-acupuncture). The control group had n = 30 because for each experimental treatment conducted on a volunteer's hemi-face, there was a control treatment on the other hemi-face. In G1, medication was given with EA, with needles placed at predetermined points (ST 4 [Dicang], M-HN-18 [Jiachengjiang], CV 24 [Chengjiang], ST 5 [Daying], ST 6 [Jiache], and point A1 [YNSA]). For electrostimulation, the device used delivered transcutaneous electrical nerve stimulation of a burst type, with intensity and frequency variations of T = 220 ms and F = 4 Hz (30 minutes, 2 × /week). In G2, in addition to the medication, laser irradiation (at 780 nm) was applied on acupuncture points (at 0.04 cm², 70 mW, 6 s/point, 0.42 J/point, 10 J/cm², 2 × /week). All volunteers were evaluated before and during the 4 months following the surgery. Tactile sensitivity was assessed by mechanical brushing (brush #s 2 and 12) and by a 2-point discrimination test, using a bow compass. A pain test was performed with a pulp electrical test that stimulates intact nerves of the dentin-pulp complex. A Kaplan-Meier test was performed, and survival curves were plotted for comparison between groups. Cox regression analysis was also conducted (α = 0.05). Results: There were no statistically significant differences among the groups for the 2-point discrimination test (brushes #2 and #12) on the buccal mucosa region and for the pulp test on all evaluated regions. However, the tactile test using brush #12 revealed significant differences between G1 and the other groups when considering the lower lip (P = 0.024) and chin (P = 0.028) areas. Conclusions: Only EA was able to influence-using the brushing test (brush #12)-the return of tactile sensitivity on the chin and lower lip positively after combined orthognathic surgery and genioplasty.
