Pharmacological Treatment on the Recovery of Neurosensory Disturbance After Bilateral Sagittal Split Osteotomy

September 8, 2022 updated by: Pedro Sole Ventura, Universitat Internacional de Catalunya

Pharmacological Treatment on the Recovery of Neurosensory Disturbance After Bilateral Sagittal Split Osteotomy: a Randomized, Double-blind Trial

The bilateral sagittal split osteotomy (BSSO) of the mandible is one of the most used surgical techniques to achieve a harmonious jaw relation in the context of orthognathic surgery. Nevertheless, one of its main complications is neurosensory damage to the inferior alveolar nerve, which can cause severe impact in the quality of life on patients who suffer from it permanently. The purpose of this randomized clinical trial is to provide rigorous scientific evidence of the pharmacological effect of 1) Melatonin, 2) combination uridine triphosphate (UTP), cytidine monophosphate (CMP), and hydroxycobalamin (UTP/CMP/hydroxycobalamin) and 3) hydroxycobalamin regarding neurosensory disturbances incidence and persistence after BSSO.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study will be done according to the international standards of the Helsinki convention for medical research and approved by the scientific ethics committee of Universidad de los Andes Clinic.

All subjects will give their signed consent to participate of this clinical research.

This clinical randomized trial will be double-blinded as both the patient and the surgeon will not know the treatment used until the experiment is over. The randomization will be done using "random.org" software to assign participants into 4 groups. Groups A, B and C will receive the medication, whereas the Group P will receive a placebo.
