Does Perioperative Glucocorticosteroid Treatment Correlate With Disturbance in Surgical Wound Healing After Treatment of Facial Fractures? A Retrospective Study

Role of procalcitonin, interleukin-6 and interleukin-10 as a predictive marker for the use of perioperative steroid in maxillofacial trauma patients

Maxillofacial trauma often brings significant challenges for surgeons in terms of preoperative oedema. Steroids offer oedema reduction, yet potentially increase the risks of postoperative infection. This study explores procalcitonin (PCT), as a marker for bacterial infection risk, and interleukins IL-6 and IL-10, which respectively signify pro-inflammatory and anti-inflammatory responses, as potential indicators of infection and inflammation in these trauma cases and thereby aid in refining perioperative guidelines for the use of steroids. A prospective study was conducted at a tertiary public hospital in India from 2019 to 2022 on patients >18 years with facial trauma. After specific exclusions, patients were randomised into steroid (Group A) and non-steroid (Group B) groups. Various parameters including oedema, PCT, IL-6, and IL-10 levels were measured and analysed using SPSS software. Out of 80 patients, 44 were in Group A and 36 in Group B. Post-24 hours, Group A showed significant oedema reduction, with 25 patients displaying a decline to mild oedema, versus 10 patients in Group B (p = 0.034). However, Group A witnessed a higher infection risk, with 20 patients showing positive wound cultures versus three in Group B. Subgroup analysis revealed a link between higher PCT levels and infections (p = 0.039). Additionally, Group A showed less intraoperative bleeding and reduced operating time. While perioperative steroids mitigate swelling, they might increase postoperative infection risk. Elevated PCT levels indicate potential wound infections, suggesting those patients should avoid perioperative steroids. IL-6 and IL-10 trends during perioperative phases can predict pronounced oedema outcomes.

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 effects of Kinesio tapes on facial swelling following bimaxillary orthognathic surgery in the supraclavicular region

BACKGROUND

Several osteotomies are required for orthognathic surgery to reposition the jaws correctly. This study aimed to evaluate whether Kinesiotaping can reduce swelling, pain, and trismus following orthognathic surgery of the facial skull.

MATERIALS AND METHODS

The present study consists of two phases. In the split-mouth phase, 16 skeletal class III patients underwent Bimax Orthognathic surgery, and Kinesiological tape (KT) was applied on one half of the face. In the prospective case-control phase, 30 patients were divided into two groups. Kinesio tape was applied on both sides of the face of the Kinesio group, and pressure dressing and ice therapy were used for the second group. The tape was parallel to the lower border of the mandible along its entire length, tangent to the labial commissure area on the studied side. The tape was placed in place for 5 days. Edema was evaluated by measuring the distance from the menton to the lower edge of the tragus. The maximum mouth-opening trismus was evaluated, and the VAS index was used to evaluate pain.

RESULTS

There was evidence of swelling reduction after KT; within the same study, differences between the left and right sides as well as for the same side were statistically significant (p < 0.001). As a result of tapping lymphatic Kinesio tape on the affected area, tension was reduced, and lymphatic circulation was restored. Blood and lymph microcirculation was improved, enabling the body to heal itself.

CONCLUSION

Kinesio tape reduced swelling after orthognathic surgery in a positive way. As a simple, non-traumatic, economical method, Kinesio taping seems promising.

Multimodal Analgesia in the Aesthetic Plastic Surgery: Concepts and Strategies

Postoperative pain management is crucial for aesthetic plastic surgery procedures. Poorly controlled postoperative pain results in negative physiologic effects and can affect length of stay and patient satisfaction. In light of the growing opioid epidemic, plastic surgeons must be keenly familiar with opioid-sparing multimodal analgesia regimens to optimize postoperative pain control.

Methods

A review study based on multimodal analgesia was conducted.

Results

We present an overview of pain management strategies pertaining to aesthetic plastic surgery and offer a multimodal analgesia model for outpatient aesthetic surgery practices.

Conclusion

This review article presents an evidence-based approach to multimodal pain management for aesthetic plastic surgery.

Evaluation of effect of submucosal administration of depomedrol in management of postoperative sequelae in mandibular fractures: A randomized clinical trial study

Introduction:

The mandible is a commonly fractured bone in the face, a fact related to its prominent and exposed position. Open reduction and internal fixation (ORIF) of mandibular fractures has been associated with trauma to the surgical site and the surrounding tissues.

Purpose:

The purpose of this study is to evaluate the effects of immediate postoperative submucosal depomedrol administration on postoperative pain, edema, and trismus after ORIF for mandibular fractures.

Materials and Methods:

We conducted a prospective, randomized, controlled, double-blind study of forty patients who required ORIF for mandibular fractures under general anesthesia. The patients were divided into two groups, an experimental group who received immediate postoperative submucosal 40 mg of depomedrol injection through the surgical incision site, and a control group who did not receive any drug. Pain was assessed using a Visual Analog Scale score and the frequency of analgesic consumption at various postoperative intervals. The maximum interincisal distance and facial measurements were compared before surgery and at 24, 48, 72 h, and 7 days after surgery.

Results:

Statistical analysis of the data indicated a significant decrease in edema, trismus, and pain in the depomedrol group. No clinically apparent infection, disturbance of wound healing, or other corticosteroid-related complications were noted.

Conclusion:

The results of our study suggest that submucosal administration of depomedrol injection after ORIF for mandibular fractures is effective in reducing postoperative pain, edema, and trismus.

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.

Fifteen-Year Review of the American Board of Plastic Surgery Maintenance of Certification Tracer Data: Clinical Practice Patterns and Evidence-Based Medicine in Zygomatico-Orbital Fractures

BACKGROUND

From 2005 to 2020, the American Board of Plastic Surgery collected data on 20 common plastic surgery operations as part of the Maintenance of Certification process. These data allow the authors to examine national trends in zygomatico-orbital fracture repair over a 15-year period.

METHODS

Tracer data for zygomatico-orbital fracture repair were reviewed in cohorts from 2005 to 2013 and 2014 to 2020. Results were categorized based on their presence in evidence-based medicine articles published during this period. Differences between years were assessed using the t test or chi-square test as appropriate.

RESULTS

Four hundred thirty patients were included as of March of 2020. Average age was 37 years (range, 6 to 85 years), and 76 percent were male. Operations took place on average 10 days from injury. There were significant decreases in the use of subciliary (31.9 percent versus 10.0 percent; p < 0.001), gingival buccal (84.3 percent versus 56.4 percent; p < 0.001), and lateral brow (45.2 percent versus 22.3 percent; p < 0.001) incisions, with an increase in lower lid external incisions (15.2 percent versus 30.9 percent; p < 0.001); 2.7 percent of patients had a complication requiring readmission and 4.5 percent required reoperation. The incidence of postoperative diplopia was 7.7 percent, and the infection rate was 1.7 percent.

CONCLUSIONS

This article reviews the American Board of Plastic Surgery tracer data for zygomatico-orbital fracture repair. The Maintenance of Certification tracer data provide a national database with longer follow-up and more specific information than comparable databases. Analysis of these data over time enables the authors to describe practice trends and gives surgeons the opportunity to compare their outcomes to national norms.

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.

Comparing the Efficacy of Twin Mix and Lidocaine for Inferior Alveolar Nerve Blocks in Patients With Symptomatic Irreversible Pulpitis

This randomized, active-controlled, double-blind, prospective clinical trial evaluated the anesthetic efficacy of 2% lidocaine with 1:200,000 epinephrine versus an admixture of 2% lidocaine with 1:200,000 epinephrine and 1 mL of 4 mg dexamethasone (Twin mix) for inferior alveolar nerve blocks (IANBs) in patients with symptomatic irreversible pulpitis (SIP) of the mandibular molars. Seventy-eight patients with SIP of mandibular molars were randomly allocated to the 2 groups of 39 subjects. All patients were required to have profound lip numbness within 10 minutes of local anesthetic deposition. The efficacy of pulpal anesthesia was confirmed by absence of pain or mild pain (Heft-Parker visual analogue scale ≤54 mm) during access cavity preparation and placement of glide path files. The collected data were subjected to independent t test, chi-square test, and Fisher exact test using SPSS software version 20.0 at a significance level of 0.05. IANB success rates for the lidocaine group and the Twin mix group was 66% and 68% respectively, which was not a statistically significant difference (p > .05). This study demonstrated that the anesthetic efficacy of Twin mix was equivalent to 2% lidocaine for IANBs in teeth with SIP.

Recommendations from the Italian intersociety consensus on Perioperative Anesthesa Care in Thoracic surgery (PACTS) part 2: intraoperative and postoperative care

Introduction

Anesthetic care in patients undergoing thoracic surgery presents specific challenges that require a multidisciplinary approach to management. There remains a need for standardized, evidence-based, continuously updated guidelines for perioperative care in these patients.

Methods

A multidisciplinary expert group, the Perioperative Anesthesia in Thoracic Surgery (PACTS) group, was established to develop recommendations for anesthesia practice in patients undergoing elective lung resection for lung cancer. The project addressed three key areas: preoperative patient assessment and preparation, intraoperative management (surgical and anesthesiologic care), and postoperative care and discharge. A series of clinical questions was developed, and literature searches were performed to inform discussions around these areas, leading to the development of 69 recommendations. The quality of evidence and strength of recommendations were graded using the United States Preventive Services Task Force criteria.

Results

Recommendations for intraoperative care focus on airway management, and monitoring of vital signs, hemodynamics, blood gases, neuromuscular blockade, and depth of anesthesia. Recommendations for postoperative care focus on the provision of multimodal analgesia, intensive care unit (ICU) care, and specific measures such as chest drainage, mobilization, noninvasive ventilation, and atrial fibrillation prophylaxis.

Conclusions

These recommendations should help clinicians to improve intraoperative and postoperative management, and thereby achieve better postoperative outcomes in thoracic surgery patients. Further refinement of the recommendations can be anticipated as the literature continues to evolve.

Risk Factors for Reoperation in Patients Hospitalized for Odontogenic Infections

PURPOSE

One of the most common adverse events after treatment of severe odontogenic infections is the need for a second procedure. The identification of risk factors for reoperation could help surgeons predict the need for reoperation or even tailor treatment to avoid this complication altogether. The purpose of this study was to identify risk factors associated with reoperation in patients hospitalized with odontogenic infections.

PATIENTS AND METHODS

We designed a retrospective cohort study from an eligible population of all patients treated at our institution for an odontogenic infection with incision and drainage under general anesthesia from August 1, 2015, to June 30, 2019. The primary outcome variable was a return to the operating room because of treatment failure. The potential predictor variables included demographic characteristics, history or physical examination findings from admission, admission laboratory values, initial computed tomography results, and medications provided during treatment. Statistical analysis was performed using the χ² test and logistic regression, and from these results, a multiple logistic regression model was created.

RESULTS

A total of 223 patients were included in the study. Men comprised 50.7% of the study population, and the average age was 38.9 ± 13.3 years. The mean number of involved spaces was 2.6 ± 1.7 spaces. Reoperation was performed in 25 patients (11.2%). In the adjusted model, an increased number of involved spaces (odds ratio [OR], 1.9; 95% confidence interval [CI], 1.3 to 2.7) and increased age (OR, 1.05; 95% CI, 1.004 to 1.09) were associated with increased odds of reoperation, and antibiotic therapy with a penicillin-type antibiotic (OR, 0.1; 95% CI, 0.04 to 0.5) and dexamethasone use (OR, 0.9; 95% CI, 0.8 to 0.98) were negatively associated with reoperation.

CONCLUSIONS

Further studies could be directed at determining whether certain timing or dosing regimens of dexamethasone could be helpful in reducing adverse outcomes in patients with odontogenic infections or determining feasible strategies when penicillin allergies are reported.

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.

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.

Multimodal Analgesia, Current Concepts, and Acute Pain Considerations

PURPOSE OF REVIEW

Management of acute pain following surgery using a multimodal approach is recommended by the American Society of Anesthesiologists whenever possible. In addition to opioids, drugs with differing mechanisms of actions target pain pathways resulting in additive and/or synergistic effects. Some of these agents include alpha 2 agonists, NMDA receptor antagonists, gabapentinoids, dexamethasone, NSAIDs, acetaminophen, and duloxetine.

RECENT FINDINGS

Alpha 2 agonists have been shown to have opioid-sparing effects, but can cause hypotension and bradycardia and must be taken into consideration when administered. Acetaminophen is commonly used in a multimodal approach, with recent evidence lacking for the use of IV over oral formulations in patients able to take medications by mouth. Studies involving gabapentinoids have been mixed with some showing benefit; however, future large randomized controlled trials are needed. Ketamine is known to have powerful analgesic effects and, when combined with magnesium and other agents, may have a synergistic effect. Dexamethasone reduces postoperative nausea and vomiting and has been demonstrated to be an effective adjunct in multimodal analgesia. The serotonin-norepinephrine reuptake inhibitor, duloxetine, is a novel agent, but studies are limited and further evidence is needed. Overall, a multimodal analgesic approach should be used when treating postoperative pain, as it can potentially reduce side effects and provide the benefit of treating pain through different cellular pathways.

Perioperative Glucocorticoid Administration Improves Elbow Motion in Terrible Triad Injuries

PURPOSE

Among patients who undergo surgical treatment of terrible triad elbow injuries (TTEI), we hypothesized that those who received perioperative glucocorticoid (GC) therapy would have improved postoperative pain and range of motion (ROM) and a similar complication rate compared with patients who did not receive GC therapy.

METHODS

We retrospectively identified 26 patients who underwent surgical treatment of TTEI from 2009 to 2015. Thirteen patients received a single intraoperative dose of 10 mg intravenous dexamethasone followed with a 6-day oral methylprednisolone taper course (GC group), and 13 did not (control group). After surgery, patients were placed in an orthosis at 90° flexion with the forearm in pronation for 2 weeks, after which ROM was initiated. Patients were seen in clinic at 2, 6, 12, and 24 weeks after surgery, at which time numeric pain scale scores and ROM data were collected and any complications were noted.

RESULTS

Compared with the control group, the GC group had a greater flexion-extension arc of motion at 24 weeks (132.5° vs 105.5°); significant differences were not found at earlier time points. Supination measurements were significantly greater for the GC group at every time point with a difference at final follow-up of 23.2° (61.0° vs. 84.2°). There were 5 complications in the control group (35.8%), 3 of which required additional surgery, and 3 complications in the GC group (23.1%), 1 of which required another surgery. No postoperative infections were found in either group.

CONCLUSIONS

Perioperative glucocorticoid administration is associated with improved ROM after surgical treatment of TTEI. Flexion-extension, pronosupination arc of motion, and overall supination were significantly improved. Postoperative pain scores and complication rates were similar between GC and control groups.

Surgical treatment of unilateral zygomaticomaxillary complex fractures: A 7-year observational study assessing treatment outcome in 153 cases

This study investigates treatment outcome in zygomaticomaxillary complex (ZMC) fracture repair.

METHODS

The medical records and CT-images of patients that received treatment for a unilateral ZMC fracture in 2005-2011 were studied. ZMC fractures were categorised as incomplete (type A), tetrapod (type B) or comminuted (type C). The incidence of sequelae, wound infection and secondary surgical interventions was analysed per fracture category.

RESULTS

A total of 153 patients were treated in the selected period. Persisting sensory disturbances in the area innervated by the infraorbital nerve were observed in 50 cases (37%), facial asymmetry in 19 cases (14%), enophthalmos in 10 cases (7%) and persisting diplopia in 9 cases (7%). Wound infection occurred in 6 cases (4%). Secondary surgical procedures of the ZMC, orbital floor, and/or extraocular muscles were performed in 14 cases (9%). C-type fractures were associated with more secondary corrections for ZMC malreduction (12%, p = 0.03), more secondary reconstructions of the orbital floor (10%, p < 0.01), and more functional corrections of diplopia by extraocular muscle correction (5%, p = 0.02).

CONCLUSION

Treatment outcome in C-type ZMC fractures is less favourable than treatment outcome in A-type and B-type fractures. Intraoperative imaging, surgical navigation devices and 3D-planning software may improve treatment outcome in C-type ZMC fractures.

NMDA Receptor Antagonists, Gabapentinoids, α-2 Agonists, and Dexamethasone and Other Non-Opioid Adjuvants: Do They Have a Role in Plastic Surgery?

BACKGROUND

Inadequate pain control and opioid-related adverse effects result in delayed patient recovery and discharge times. Adjuvants help to improve the quality of analgesia and decrease opioid consumption, consequently decreasing opioid-related effects, such as nausea and vomiting, sedation, ileus, and respiratory depression. We review the mechanisms and clinical evidence for nonopioid adjuvants.

METHODS

MEDLINE, EMBASE, and the Cochrane Register were searched for meta-analyses, systematic reviews, and randomized, controlled trials that compared the adjuvants ketamine, gabapentin, pregabalin, dexmedetomidine, clonidine, and dexamethasone with placebo. Keywords used in the search included "plastic surgery," "reconstructive surgery," "opioid," "pain," "analgesia," and the names of each adjuvant. The references of included studies were searched for additional relevant studies.

RESULTS

Ketamine was found in 6 meta-analyses to have a significant reduction in opioid requirements and may reduce the hyperalgesia associated with opioids. This seems to be most beneficial in surgeries where high postoperative pain is expected. Multiple robust trials have demonstrated that the gabapentinoids and α-2 agonists significantly improve quality of analgesia and decrease opioid consumption. Two recent meta-analyses found that a single low-dose of dexamethasone used for postoperative nausea and vomiting prophylaxis may also improve postoperative analgesia. There is also emerging evidence for the use of low-dose naloxone, adenosine, and neuraxial neostigmine and acupuncture as part of a successful multimodal pain management regimen.

CONCLUSIONS

Although there is a lack of studies specifically focused in the plastic and reconstructive surgery patient population, the existing literature provides information about when the above adjuvants are likely to have the greatest impact.

A randomized clinical trial of the effects of submucosal dexamethasone after surgery for mandibular fractures

PURPOSE

To evaluate the effects of immediate postoperative submucosal dexamethasone administration on postoperative pain, edema, trismus, and mandibular functions after open reduction and internal fixation (ORIF) for mandibular fractures.

PATIENTS AND METHODS

We conducted a prospective, randomized, controlled, double-blind study of 40 patients who required ORIF for mandibular fractures under general anesthesia. The patients were divided into 2 groups, an experimental group (n = 20) who received immediate postoperative submucosal 8 mg of dexamethasone through the surgical incision site, and a control group (n = 20) who did not receive dexamethasone. Pain was assessed using a visual analog scale (VAS) score and the frequency of analgesic consumption at the various postoperative intervals. The maximum interincisal distance and facial measurements were compared before surgery and at 24, 48, and 72 hours and 7 days after surgery. The difficulty in mandibular function after surgery was graded as mild, moderate, or severe.

RESULTS

The analgesic drugs required 2 hours after surgery and the VAS score 72 hours after surgery were significantly less (P < .05) in the experimental group than in the control group. The total number of diclofenac tablets required by the experimental group was less than that for the control group, but the difference was not statistically significant. The control group had significantly increased swelling (P < .05) compared with the experimental group from preoperatively to 24 hours postoperatively (experimental group 0.115 ± 0.143, control group 0.253 ± 0.173). No statistically significant difference was present in the mouth opening or difficulty in mandibular function at the different follow-up intervals between the 2 groups (P > .05).

CONCLUSION

The results of our study suggest that submucosal administration of dexamethasone after ORIF for mandibular fractures is effective in reducing postoperative pain and edema.

Influence of Kinesiologic Tape on Post-operative Swelling After Orthognathic Surgery

INTRODUCTION

Orthognathic surgery involves making several osteotomies that lead to varying degrees of post-operative swelling. The use of KT may be beneficial for postoperative treatment after head and neck surgery, accelerating drainage of tissue reaction or haemorrhages. The goal of this study was to find out if the application of KT prevents or improves swelling, pain and trismus after orthognathic surgery, improving patients' postoperative quality of life.

MATERIALS AND METHODS

In this double-blinded, randomized, control trial, 24 patients in whom bimaxillary orthognathic surgery was indicated, were included. Before surgery each patient alternatively was randomly included in the study group (treated with K-Taping(®) and corticosteroid) or in the control group (treated with corticosteroid). In the present study a MakerBot(®) Digitizer 3D™ was used to assess accurate volume measurements. All swelling measurements were expressed as total 3-D area of the landmarks (cm(2) ) in T0 pre-operative, T1 fourth day after surgery.

RESULTS

The differences T0-T1 are highly significant (p < 0.01) between group 1 or study group (treated with K-taping(®)) and group 2 (control group).

DISCUSSION

The use of KT appears promising, because it is simple to carry out, less traumatic, economical, can be performed everywhere in the world, free from side effects on the body. Even when swelling persists, KT gives patients the impression of a minor swelling detracting them from their pain and morbidity. Further studies have to be performed to find out if KT can reduce or replace the need for additional medications such as the use of steroids.

Dexamethasone reduces nausea and vomiting but not pain after thyroid surgery: a meta-analysis of randomized controlled trials

BACKGROUND

Postoperative nausea and vomiting (PONV) is a common complication after thyroidectomy. The aim of this article was to evaluate the efficacy of dexamethasone for prevention of PONV and pain in patients undergoing thyroidectomy.

MATERIAL AND METHODS

We performed this meta-analysis based on the QUORUM (Quality of Reporting of Meta-analyses) guidelines. Our study included randomized controlled trials (RCTs) that compared preoperative single-dose administration of dexamethasone with no dexamethasone in patients undergoing thyroidectomy. The primary outcome was occurrence and severity of PONV, and the secondary outcomes included pain, use of analgesics, and steroid-related complications.

RESULTS

Seven RCTs were included, with a total of 611 patients. A statistically and clinically significant difference in the incidence and severity of PONV was found in favor of dexamethasone (SMD, 0.23; 95% CI, 0.13-0.41; P<0.00001; SMD, 0.53; 95% CI, -1.03 to -0.03; P=0.04). However, there was no significant difference in reduction of pain severity and analgesic consumption in using dexamethasone (SMD, -0.83; 95% CI, -1.85 to 0.18; P=0.14; SMD, -0.19; 95% CI, -0.43 to 0.04; P=0.10). No steroid-related complications were noted.

CONCLUSIONS

A single preoperative administration of dexamethasone reduced the incidence and severity of PONV but not pain severity and analgesic consumption in patients undergoing thyroidectomy. Further studies with a larger sample size are needed to further explore the efficacy of dexamethasone on postoperative pain severity and analgesic consumption.

Pulp necrosis of teeth retained at the mandibular fracture site and the effect of dexamethasone on its occurrence

OBJECTIVES

The main purpose was to determine the occurrence of pulp necrosis (PN) of teeth retained at the mandibular fracture site. An additional purpose was to investigate whether perioperative use of dexamethasone increases the risk of PN.

PATIENTS AND METHODS

A follow-up study on 24 adult dentate patients with mandibular body, symphysis or parasymphysis fracture. These patients had been selected from a larger cohort who had participated in a randomized study of maxillofacial fractures and dexamethasone. All patients who were suspected of having a need for endodontic treatment were evaluated by an endodontist.

RESULTS

PN was diagnosed in six patients (25.0%) in one or two teeth. Of a total of 33 teeth situated in the fracture line, six (18.2%) were diagnosed as having PN. PN was more common in teeth in which the fracture line ran through the apex (21.7%) than in those in which the fracture line was in contact with the tooth cranially to the apex (10.0%). The association between PN and dexamethasone was not significant.

CONCLUSION

PN is common after mandibular fractures, particularly when the fracture line runs through the apex of the tooth. Use of short-term, high-dose dexamethasone perioperatively did not significantly increase the risk for PN.

Effects of perioperatively administered dexamethasone on surgical wound healing in patients undergoing surgery for zygomatic fracture: a prospective study

OBJECTIVE

The aims of the study were to clarify the occurrence of disturbance in surgical wound healing (DSWH) after surgery of zygomatic complex (ZC) fractures and to determine whether perioperatively applied dexamethasone increases the risk for DSWH.

STUDY DESIGN

Of 64 patients who were included in a single-blind prospective trial, 33 perioperatively received a total dose of 10 mg or 30 mg of dexamethasone. The remaining 31 patients served as controls.

RESULTS

DSWH occurred in 9 patients (14.1%). Occurrence of DSWH was 24.4% in patients who received dexamethasone and 3.2% in controls. The association between DSWH and dexamethasone was significant (P = .016). Intraoral approach also was associated with DSWH significantly (P = .042). No association emerged between DSWH and age, gender, time span from accident to surgery, or duration of surgery.

CONCLUSIONS

DSWH occurred significantly more frequently in patients who received perioperative dexamethasone. Because of increased risk of DSWH, perioperative dexamethasone cannot be recommended in open reduction and fixation of ZC fractures.

A prospective randomized double-blind study to assess the latency and efficacy of twin-mix and 2% lignocaine with 1:200,000 epinephrine in surgical removal of impacted mandibular third molars: a pilot study

INTRODUCTION

A prospective randomized double-blind study was conducted to assess the latency and duration of pterygomandibular nerve block with a mixture of 1.8 ml 2% lignocaine with 1:200,000 epinephrine and 1 ml of 4 mg dexamethasone and its impact on postoperative sequelae of surgical extraction of impacted mandibular third molars.

MATERIAL AND METHODS

The study was conducted as a prospective randomized double-blind clinical trial on 20 patients with bilateral impaction of mandibular third molars. A total of 40 interventions were included for the study, 20 with 2% lignocaine with 1:200,000 epinephrine (study group C, control) and 20 with the twin-mix (study group T, twin-mix), with a gap of 1 month between two interventions in a single patient. After injection of the anesthetic solution, the time to anesthetic effect, duration of anesthesia, and the need to re-anesthetize the surgical site were recorded. A 10-point visual analog scale (VAS) was used to assess the overall pain intensity while injecting the study drug, during surgery, and in the postoperative period. pH of the test anesthetic solutions was also determined using a pH meter.

RESULTS

Twin-mix was found to be more basic than 2% lignocaine with 1:200,000 epinephrine. Mean VAS value for the pain/sting on local anesthetic injection/block was less in study group T. Time of onset of the local anesthetic was significantly less for the study group T, 51 ± 17.5 s when compared with patients in study group C (P less than 0.0001). The duration of soft tissue anesthesia was longer for all the patients in the study group T. On comparative evaluation between study group C and study group T, patients in the control group had more sever swelling and reduction in mouth opening in the postoperative period.

DISCUSSION

The addition of dexamethasone to lignocaine and its administration as an intra-space injection significantly shortens the latency and prolongs the duration of the soft tissue anesthesia, with improved quality of life in the postoperative period after surgical extraction of mandibular third molars.

Influence of kinesiologic tape on postoperative swelling, pain and trismus after zygomatico-orbital fractures

Surgical treatment of zygomatico-orbital (ZO) fractures is a common procedure in maxillofacial surgery. Often accompanied by pain, trismus and swelling, postoperative morbidity is a major disadvantage, affecting patients' quality of life. The appliance of kinesiologic tape (KT) improves the blood and lymph flow, removing congestions of lymphatic fluid and haemorrhages. The aim of this study was to find out if the application of kinesiologic tape prevents or improves swelling, pain and trismus after zygomatico-orbital fracture surgery, improving patients' postoperative quality of life. A total of 30 patients were assigned for treatment of zygomatico-orbital fractures and were randomly divided into treatment either with or without kinesiologic tape. Tape was applied directly after surgery and maintained for at least 5 days postoperatively. Facial swelling was quantified using a five-line measurement at six specific time points. Pain and degree of mouth opening was measured. Patient's subjective feeling and satisfaction was queried. The results of this study show that application of kinesiologic tape after zygomatico-orbital surgery significantly reduced the incidence of swelling with an earlier swelling maximum, and decreased the maximum turgidity for more than 60% during the first 2 days after surgery. Although, kinesiologic tape has no significant influence on pain control and trismus, mouth opening increased earlier after operation in the kinesiologic tape group compared to the no-kinesiologic tape group. Furthermore, patients with kinesiologic tape felt significantly lower morbidity than those without kinesiologic tape. Therefore kinesiologic tape is a promising, simple, less traumatic, economical approach, which is free from adverse reaction and improves patients' quality of life.

Dexamethasone for prevention of postoperative nausea and vomiting in patients undergoing thyroidectomy: meta-analysis of randomized controlled trials

BACKGROUND

Postoperative nausea and vomiting (PONV) is a common complication after thyroidectomy. Steroids effectively reduce nausea, pain, and inflammation; therefore, preoperative administration of steroids ought to improve these surgical outcomes.

METHODS

We conducted a systematic review of randomized controlled trials (RCTs) that compared preoperative single-dose administration of dexamethasone with no dexamethasone in patients undergoing thyroidectomy. The primary outcome was occurrence of PONV within 24 h, and the secondary outcomes were pain, use of analgesics, and steroid-related complications.

RESULTS

Five RCTs were included with a total of 497 patients. A statistically and clinically significant difference in the incidence of PONV was found in favor of dexamethasone [relative risk (RR) 0.38; 95% confidence interval (CI) 0.30-0.49). The visual analog pain score was significantly diminished (weighted mean difference, WMD)-1.50; 95% CI-2.54 to -0.46) at 24 h. The incidence of analgesics use was also reduced (RR 0.61; 95% CI 0.41-0.90) in the dexamethasone group. No steroid-related complications were noted.

CONCLUSIONS

A single preoperative administration of dexamethasone reduced the incidence of PONV and analgesic requirements in patients undergoing thyroidectomy. Prophylactic use of steroids for patients undergoing thyroidectomy is safe and should be considered for routine clinical practice.

Perioperative glucocorticosteroid treatment delays early healing of a mandible wound by inhibiting osteogenic differentiation

AIM

The purpose of this study is to investigate the effects of dexamethasone on repair of a critical size defect of the mandible in male Sprague-Dawley rats.

MATERIALS AND METHODS

Fifty rats were divided into 2 groups: saline control and dexamethasone-treated groups. A 1 mm × 3 mm full-thickness bone defect was created at the inferior border of the mandible. Saline or dexamethasone was administered once a day for 5 days after postoperative palinesthesia. On days 1, 3, 6, 10 and 17, after cessation of drug administration, 5 samples from each group were analysed. The bone defect healing process was examined and analysed by stereology, radiology, histology and histochemical staining for total collagen, tartrate-resistant acid phosphatase staining for osteoclasts and immunohistochemical staining for the COX-2, RUNX2 and osteocalcin antigens.

RESULTS

The dexamethasone-treated rats exhibited significantly lower radiopacity properties compared to the control rats. Histological staining revealed that the osteogenic differentiation and maturation of a callus in the defect region was significantly delayed from day 1 to day 10 in the dexamethasone group after cessation of drug administration compared to the control group. Consistent with the histological data, the level of total collagen protein was significantly lower in the dexamethasone group than in the control group. However, there was no significant difference between the 2 groups at day 17. Immunohistochemical analysis of COX-2, RUNX2 and osteocalcin expression showed that, at day 1, COX-2 and RUNX2 expression in the dexamethasone group was significantly lower than in the control group. There was no significant difference in osteocalcin expression between the two groups at each time point. There was no significant difference in the number of osteoclasts between the two groups.

CONCLUSION

In a model of bone healing of a mandible defect, dexamethasone-treated rats exhibited impaired osteogenic differentiation and maturation due to the inhibition of COX-2, osteogenic gene, RUNX2 and collagen protein expression, which resulted in delayed bone repair. Although perioperative short-term therapy did not exhibit long-term effects on wound healing of the maxillofacial bone, the application of glucocorticoids should be cautiously considered in the clinic.
