Efficiency of Different Treatment Modalities on Radiation Induced Trismus for Maxillofacial Cases

Aim: to compare different treatment modalities for radiation induced trismus for maxillofacial patients methods:45 participants (20 females and 25 males) with trismus and pain following head and neck cancer and underwent radiation therapy were enrolled in this study . patients were divided into three groups : group1 received threaded tapered screw appliance therapy, patients in group II received low-level laser therapy and patients in group III received low-level laser therapy in addition to threaded tapered screw appliance therapy.

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

All patients received treatment according to their group: For group I, received threaded tapered screw appliance therapy . The appliance was digitally designed by solid works programs for 3rd CAD design software to obtain the STL file format. The virtual design of was approved. The printer was loaded with material of 3D-printed denture base. The appliance was printed.

For group II received low-level laser therapy, the laser type was of diode laser.The laser apparatus consisted of a hand piece with two attachments: either a plastic tip was attached to the same hand piece to transfer laser energy intro-orally when it was used to irradiate the lateral pterygoid muscle, or a specially designed optic prism was attached to the tip of the prism for extraoral application on extra oral muscles. All patients in this group received low level laser therapy twice times a week for 6 weeks totaling 12 sessions. In each session, the laser beam was applied in a three phases treatment protocol as follows: (a) The insertion of the lateral pterygoid muscle into the condylar neck and disc was treated in the first phase by applying a laser beam 1 cm anterior to the condyle below the zygomatic arch. (b) Tender spots in the masseter and temporalis muscles that were found during the initial assessment were exposed to radiation during the second phase. (c) The lateral pterygoid muscle origin was exposed to radiation in the third phase, which was performed with the mouth slightly open and intro-orally posterior to the final molar. During each phase, the laser was operated for two minutes per area at a wavelength of 810 nm and a peak output of 500 mW. It was applied continuously, a little distance away from the tissues. The laser probe was positioned perpendicular to the target area. Prior to usage, the laser was calibrated. Protective glasses were worn by the clinician and the patients. For group III, received low-level laser therapy in addition to threaded tapered screw appliance therapy as mentioned previously in group I and group II. Concurrent with the initial low level laser therapy session, screw tapered appliance was used for the first time.

Throughout the trial, no medication was administered to any of the groups. The patients were not allowed to use any painkillers or analgesics.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
patient satisfaction(Quality of life) assessed by the Gothenburg Trismus Questionnaire (GTQ) which is a trismus-specific self-administered questionnaire
Time Frame: six months
was assessed using Gothenburg trismus questionnaire witha scale ranging between 0-100, where a higher score indicates greater perceived dysfunction due to trismus. It contains three main domains 1-Jaw related problems 2- Eating limitations 3-Muscular tension
six months
Satisfaction assessed by the (VAS)visual analogue scale of pain
Time Frame: six months
the patients filled out a self-assessment 0 to 10 visual analogue scale (VAS) for Pain (where 0 equals no pain and 10 is the most severe pain)
six months
