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

OBJECTIVE: This study aimed to comprehensively review the literature and provide a practical guide for optimizing drug regimens and supplementation related to orthognathic surgery. METHODS: The authors conducted a thorough review of the existing literature, following the PRISMA-ScR guidelines. Various types of studies except case reports and reviews were included. The study applied specific inclusion criteria, focusing on perioperative and/or postoperative drugs, medications, or supplementation related to orthognathic surgery. RESULTS: This guide included 78 studies on various medications in orthognathic surgery. It encompasses clinical trials, cohort studies, cross-sectional studies, prospective and retrospective studies. The topics covered include antibiotics, analgesics, corticosteroids, antiemetics, hemostatic agents, local anesthetics, herbal medicine, and botulinum toxin. Pain and edema control involved specific medications, while local anesthesia utilized ropivacaine and bupivacaine. The guide also discusses mineral and vitamin supplementation. The effectiveness of hemostatic agents and antiemetics was highlighted. CONCLUSION: Pain management, reduced swelling, enhanced wound healing, and faster recovery are among the advantages. In addition to the standard drugs and medications, the inclusion of vitamin and mineral supplements, tranexamic acid, postoperative anesthetic blocks, and preemptive antiemetics is anticipated to offer various benefits in orthognathic surgery, despite the limited available evidence.

Photobiomodulation as oedema adjuvant in post-orthognathic surgery patients: A randomized clinical trial.

OBJECTIVE: Photobiomodulation therapy (PBMT) has been used in multiple applications in general medicine as powerful anti-inflammatory, analgesic and reducing oedema in different parts of the body. The aim of this study is to compare the effect on post-surgical oedema after mandibular orthognathic surgery, between two different laser power densities and oral medication with non-steroidal anti-inflammatory. MATERIALS AND METHODS: In a randomized clinical trial, on 60 patients who were subject to mandibular orthognathic surgery were divided into three groups. All groups received sodium naproxen 250mg every 8hours for 6days. Two groups were irradiated with two different laser application protocols and the other was a control group. In G1 group the irradiation parameters three times per week for two weeks were: 940nm, in continuous mode, 2.5W, 120s, 85.71J/cm2, 0.89W/cm2, over the right and left side with a distance from the skin surface of 1mm with the whitening handpiece (spot size of 2.8cm2). In G2, the irradiation parameters three times a week for two weeks were: 940nm, in continuous mode, 4.1W, 120s, 68.33J/cm2, 0.58W/cm2 over the right and left side with a distance from the skin surface of 15mm, with the deep tissue handpiece (spot size of 7.1cm2). In all the groups, millimetric facial measurements were taken from tragus to lateral commissure, and from lateral commissure to gonion in both sides. RESULTS: All differences between T1 and T6 were significant for the three groups, (paired T, P<0.05). The differences between the groups were generally not significant (P>0.05) except for commissure - right and left gonion when compared G1 vs CG (P<0.05) and G2 vs CG (P<0.05). Initial changes (T1-T2) between groups were significantly different except for the measurement from commissure to right tragus G1 vs CG (P=0.411) and from commissure to left tragus G2 vs CG (P=0.94). The faster resolution of the oedema occurred in G2 group. PTBM with an energy density of 68.33J/cm2 was the most effective adjuvant to oral medication with non-steroidal anti-inflammatory, to decrease post-surgical oedema after mandibular orthognathic surgery.

Incidence of Pneumothorax Experienced After Orthognathic Surgery.

The purpose of this study is to evaluate the frequency of pneumothorax following orthognathic surgery and describe its clinical presentation. A retrospective analysis of a hospital database was carried out on consecutive patients with normal presurgical clinical assessment, laboratory findings, and chest X-ray who underwent orthognathic surgery from January 2007 to September 2018 in the Department of Oral and Craniomaxillofacial Surgery, Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine. Two patients (0.038%), 1 male (age 20 years) and 1 female (age 32 years), complained of respiratory difficulty and chest pain and were clearly diagnosed with postoperative pneumothorax by radiographic chest X-rays from a sample of 5229 consecutive patients during the study period. Intercostal drainage under local anesthesia was performed immediately and the treatment effects for both patients were satisfactory. The present study findings indicate that although orthognathic surgeries can be safely performed in patients with craniofacial anomalies, some unexpected complications such as pneumothorax may occur. Therefore, accurate postoperative follow-up must be done in every patient to monitor possible clinical complications. Patients who experience respiratory difficulty and postoperative chest pain may have pneumothorax, and once it is diagnosed, treatment should be promptly carried out to eliminate further severe sequelae.

Postoperative Orthognathic Surgery Edema Assessment With and Without Manual Lymphatic Drainage.

OBJECTIVE: To evaluate the effects of manual lymphatic drainage (MLD) on facial edema and pain in patients who underwent orthognathic surgery from patient and professional perspectives and clinical measures. METHODS: It is a randomized double-blind clinical trial, where 30 patients who underwent bimaxillary orthognathic surgery were divided into 2 groups (treatment and placebo). One group (treatment) received MLD from 2nd postoperative day, besides cryotherapy and postoperative medications. The other group (placebo) received cryotherapy, medications, and manual superficial sliding movements as placebo. For edema evaluation, facial measurements with tape and photographs were used. To evaluate patients' perception, visual analog scale for pain and edema was used. In statistical analysis, quantitative data were analyzed using Student t test for normally distributed variables and Mann-Whitney test for non-normal to find differences between groups; 5% significance level was adopted. RESULTS: No difference was found between groups in the amount of maximum developed edema (P = 0.290) nor on what day the edema peak occurred (P = 0.091). However, it was found that treatment group showed faster and greater regression of swelling compared with placebo (P < 0.001). Manual lymphatic drainage was not effective in relieving pain in these patients and nor in edema perception (P = 0.784 and P = 0.946, respectively). CONCLUSION: Manual lymphatic drainage was effective in reducing facial measurements in orthognathic surgery postoperatory. When considering patient's pain and swelling perception, no difference was found between groups.

Orthognathic treatment of dentofacial disharmonies: its impact on temporomandibular disorders, quality of life, and psychosocial wellness.

AIM: The objective of this literature review was to assess the effect of orthognathic surgical treatment on temporomandibular disorders (TMD), quality of life (QoL), and psychosocial wellness. METHODS: Journal articles and systematic reviews published in English between 1982 and 2015 were searched using PubMed, MEDLINE, and Cochrane database using the search terms "orthognathic," "temporomandibular disorders," "quality of life," and "psychosocial." The articles were then reviewed and discussed. RESULTS: Both objective and subjective parameters play a role in orthognathic treatment outcome satisfaction and QoL. Psychological factors and TMD exerted a stronger influence on patients' QoL more than objective treatment outcome measures. CONCLUSION: A paradigm shift in clinical mindset from solely objective measures to a more holistic, patient-centric approach of addressing patients' expectations and improving QoL is warranted when treating patients with dentofacial disharmonies.

Stellate Ganglion Block, Compared With Xenon Light Irradiation, Is a More Effective Treatment of Neurosensory Deficits Resulting From Orthognathic Surgery, as Measured by Current Perception Threshold.

PURPOSE: The aim of this study was to evaluate the relative effectiveness of stellate ganglion blockade (SGB) versus xenon light irradiation (XLI) for the treatment of neurosensory deficits resulting from orthognathic surgery as determined by a comparison of prospective measurements of electrical current perception thresholds (CPTs) and ranged CPTs (R-CPTs). MATERIALS AND METHODS: CPT and R-CPT in the mental foramen area were measured during electrical stimulation at 98 different sites on the body in patients who had undergone orthognathic surgery. After surgery, patients were assigned to the SGB group or the XLI group. CPT and R-CPT of the 2 groups were measured at stimulation frequencies of 2,000, 250, and 5 Hz before surgery, 1 week after surgery, and after 10 treatment sessions. Furthermore, the influence of surgical factors, such as genioplasty and a surgically exposed inferior alveolar nerve (IAN), was examined in the 2 groups. RESULTS: Patients' CPT and R-CPT values indicated a considerable amount of sensory disturbance in most cases after surgery. The change in magnitude of all CPT and R-CPT values for the SGB group decreased considerably compared with that for the XLI group after treatment. There was no correlation between CPT or R-CPT values and surgical factors (eg, genioplasty and exposure of the IAN). CONCLUSION: SGB of the IAN could be an effective method for treating neurosensory deficits after orthognathic surgery on the IAN.

Single-dose versus single-day antibiotic prophylaxis for orthognathic surgery: a prospective, randomized, double-blind clinical study.

PURPOSE: The purpose of this study was to evaluate the prophylactic value of single-dose antibiotic prophylaxis on postoperative infection in patients undergoing orthognathic surgery, compared to single-day antibiotics. MATERIALS AND METHODS: One hundred fifty patients were included in the study; 57 males and 93 females were divided into 2 groups with 75 in each group. Group 1 received a single dose of antibiotic prophylaxis and group 2 received a single day of antibiotic prophylaxis. These patients were assessed for rates of infection postoperatively after orthognathic surgery. RESULTS: Seven patients (9.3%) in group 1 developed infection, whereas 2 patients (2.6%) in group 2 developed infection. The difference in rates of infection in both groups was of interest but not statistically significant (P > .05). CONCLUSION: The results from the present study show that there is a clinically significant difference, but no statistically significant difference, between single-dose antibiotic prophylaxis and single-day antibiotic prophylaxis in reducing the rates of infection in orthognathic procedures. We recommend further studies with a larger sample size to determine whether there truly is no statistical difference between both groups.
