About

The purpose of this study is to verify the effectiveness of a systematic rehabilitative program for mastication in patients submitted to orthognathic surgery.

Full description

Orthognathic surgery can produce complications during the postoperative period - i.e. situations of acute pain and inflammation - as a consequence of fractures and incisions in the mucosa. The inadequate management of soft tissue and prolonged surgical time could be the causes of acute facial oedema, hematoma and ecchymosis in the face and neck, as well as functional disorders involving swallowing and breathing, which can affect patients' integrity.

Despite the fact that decreased muscular extensibility and strength, increased muscular fatigability, hipomobility, and alteration of the biomechanical efficiency and length of the masticatory muscles are documented clinical consequences, no systematic method of obviating such problems through muscular rehabilitation has yet been published

Experimental group

Experimental group

Description:

Inclusion criteria were: Skeletal Class III orthognathic surgery patients; adults (age above 18 years), agreement to perform orthognathic surgery and to undergo all of the necessary procedures determined by the multidisciplinary team (i.e. orthodontic preparation, clinical orofacial myofunctional and electromyographic assessment, surgery, post surgery orthodontic treatment, post surgery clinical orofacial myofunctional and electromyographic assessment and orofacial myofunctional treatment when necessary). Exclusion criteria were: previous orthognathic surgery; previous head and neck surgery; neurologic and/or systemic diseases; facial trauma; syndromes; cognitive impairment; and communication and hearing deficits.

Treatment:

Other: orofacial myofunctional treatment protocol
