Summary

In a prospective longitudinal study design, details in jaw-neck kinematics and electromyography (EMG) activity changes in patients (women and men) referred for surgical correction of basal relations between the maxilla and mandible over time; pre-operative and during follow-up 8 weeks and 18 months after surgical correction will be evaluated. The results will contribute with novel insights on jaw-neck motor function before, in short- and long-term after the surgical process. We will have blinded evaluation of outcomes.

Detailed description

Consecutive patients referred to department of Oral and Maxillofacial Surgery, Umeå University Hospital for corrective maxillofacial-mandibular surgery, will offer opportunity to be included in the study. Expected number of patients: 20 - 25 patients annually. Blinded evaluation will be pre-operative and during follow-up 8 weeks and 18 months after surgical correction.

Conditions

• Cleft Lip and Palate

Interventions

Type	Name	Description
PROCEDURE	Orthognathic surgery	Surgical corrections of the maxilla and/or the mandible. Integrated jaw-neck movement patterns, muscle activity, bite force and occlusal contact area will be registered and mapped with quantitative objective functional variables. The state-of-the-art core equipment to evaluate jaw-neck motor function in detail is located in the Movement Lab (Department of Odontology, Umeå University).
