About this study

Official title: Effect of Electroacupuncture on Paresthesias and Functional Changes in Patients Submitted to Bimaxillary Orthognathic Surgery and Mentoplasty

Goals. To evaluate the effect of electroacupuncture on paresthesia and myofunctional changes in patients undergoing bimaxillary orthognathic surgery and mentoplasty. Methodology: this is a controlled, randomized, blinded clinical trial. The sample will consist of 62 individuals in each group (general sample = 124 participants). Therefore, 124 young adults, aged between 18 and 50 years, both sexes, with at least 24 teeth, with Class II or III skeletal malocclusion, diagnosed by cephalometric radiographs, who underwent orthognathic surgery in the period from 1 to 30 days before the start of physical therapy, be available to perform the proposed postoperative treatment for six weeks. Participants will be equally and randomly distributed into two experimental groups: GF (Physiotherapy Group), GFE (Physiotherapy plus Electroacupuncture Group). The variables to be studied will be: socioepidemiological data; sensitivity assessment by the Semmes-Weinstein monofilament test; Edema assessment by the MD Anderson Cancer Center Head and Neck Lymphedema protocol, validated in Portuguese; assessment of mandibular movements using a Western-DC digital caliper; Assessment of masticatory function using the Chewing Quality Assessment Questionnaire. Data will be analyzed descriptively and organized into tables. Subsequently, the normality of continuous variables will be tested by the Kolmogorov-Smirnov test. As the variables are normally distributed, we will use parametric tests such as the paired t test, independent t test, ANOVA and Pearson's correlation. Nonparametric tests such as Wilcoxon paired signed rank test, Mann-Whitney U test, Kruskal Wallis test, Spearman correlation test will be used in case of non-normality of continuous variables. The significance level will be adjusted to 5% in all analyses.

Read the detailed description

Introduction: Among the major oral and maxillofacial surgeries called reconstructive, the one that has become popular in recent years, especially after the mandatory coverage of costs by health plans, was orthognathic surgery, so called because it is a combined procedure between orthodontics and oral and maxillofacial surgery, aiming at the correction of the masticatory system with the objective of reducing the discrepancies related to the jaws and, thus, establishing harmony between the face and the skull. Lesions of the inferior alveolar nerve (INA) are frequent due to its anatomical location, passing through the sagittal osteotomy of the mandibular ramus, where manipulation of the mandibular ramus or the structures that surround the nerve occurs during the operation. Goals. To evaluate the effect of electroacupuncture on paresthesia and myofunctional changes in patients undergoing bimaxillary orthognathic surgery and mentoplasty. Methodology: this is a controlled, randomized, blinded clinical trial. The sample was defined from a pilot study involving ten individuals, considering as an outcome the sensitivity obtained under the same experimental conditions used in this study. A two-way ANOVA with repeated measures considering two factors, group (treatment and control) and irradiation (pre-, post-6 treatment session and post-3 plot) was used to calculate the squared value of the ETA (0.033). The estimated number was 50 individuals per group. For sample calculation, α=0.05 (5% chance of type I error) and 1-β= 0.80 (% of sampling power) were considered. The sample will be increased by 20% to compensate for possible dropouts, resulting in 62 individuals in each group (overall sample = 124 participants). Therefore, 124 young adults, aged between 18 and 50 years, both sexes, with at least 24 teeth, with Class II or III skeletal malocclusion, diagnosed by cephalometric radiographs, who underwent orthognathic surgery in the period from 1 to 30 days before the start of physical therapy, be available to perform the proposed postoperative treatment for six weeks. Participants will be equally and randomly distributed into two experimental groups: GF (Physiotherapy Group), GFE (Physiotherapy plus Electroacupuncture Group). The variables to be studied will be: socioepidemiological data; sensitivity assessment by the Semmes-Weinstein monofilament test; Edema assessment by the MD Anderson Cancer Center Head and Neck Lymphedema protocol, validated in Portuguese; assessment of mandibular movements using a Western-DC digital caliper; Assessment of masticatory function using the Chewing Quality Assessment Questionnaire. Data will be analyzed descriptively and organized into tables. Subsequently, the normality of continuous variables will be tested by the Kolmogorov-Smirnov test. As the variables are normally distributed, we will use parametric tests such as the paired t test, independent t test, ANOVA and Pearson's correlation. Nonparametric tests such as Wilcoxon paired signed rank test, Mann-Whitney U test, Kruskal Wallis test, Spearman correlation test will be used in case of non-normality of continuous variables. The significance level will be adjusted to 5% in all analyses.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

sensitivity assessment (time frame: the sensitivity assessment at 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Feb 2025.
