Maxillofacial Rehabilitation Using Motor Imagery vs Sham After Orthognathic Surgery
Dento-maxillary dysmorphoses are defined as an anomaly in the relative growth of the maxilla and/or mandible. They lead to functional disorders (i.e., disturbances in chewing or oral communication) and aesthetic issues with psychological repercussions on self-esteem, affecting the quality of life of these patients. The multidisciplinary treatment involves orthodontics (duration = 18-24 months), orthognathic surgery involving the maxillary and/or mandibular bone (at 12 months), immediately followed by physiotherapy (duration = 3 months). One main goal after surgery is the recovery of month opening to restore an appropriate orofacial function. Motor imagery (mental rehearsal of a movement without actually moving) is effectively used in athletes and in rehabilitation mainly neurological but so far has not been investigated in maxillofacial rehabilitation. Considering that the effectiveness of rehabilitation is increased when physical and mental practices are combined, this leads to propose this study aiming to investigate whether the addition of motor imagery of the maxillofacial region to maxillofacial physiotherapy (based on a practice of physical therapeutic exercises) modifies the recovery of maximum mouth opening, other ranges of motion, jaw function, and quality of life in patients after orthognathic surgery compared to the addition of a control cognitive task [watching a non-emotional content film or filling out a crossword or Sudoku grid] to maxillofacial physiotherapy.
- EligibilityCriteria: Inclusion Criteria:  Volunteer after orthognathic surgery of the mandible alone or concurrently with the maxilla. Consent to participate to the study after receiving clear, loyal and appropriate information. Aged ≥ 18 years. Health care beneficiary  Exclusion Criteria:  Patient who has undergone maxillary surgery alone (e.g., LeFort I) or genioplasty. Indeed, both of these surgeries typically have a favorable and rapid recovery without the need for maxillofacial physiotherapy. Patient unable to imagine a maximum mouth opening movement (i.e., score = 1, no mental image / no sensations) on the 5-point Likert scale used during the administration of the Tongue Month Imagery Questionnaire (TMIQ). Ongoing participation in another research that aim to evaluate an intervention likely to improve the neurological or functional recovery introducing an experimental bias. Patients not undergoing rehabilitation in the study centers. Patients under guardians, curators, or legal protection. Pregnant or lactating patients. - HealthyVolunteers: No - Gender: All - MinimumAge: 18 Years - StdAgeList: Adult, Older Adult
