An interventional study of Early Physiotherapy in Mandibular Range of Motion, Pain and Sensorial Disturbance, sponsored by University of the Basque Country (UPV/EHU). Status unknown at 1 site in Spain. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2018-03-14.

Several studies describe that the maximum mandibular opening decreases 60% -70% immediately after orthognathic surgery (OS) and other variables, including laterotrusion, movement speed and facial mimic also decrease drastically. In addition, patients frequently experience temporary or permanent sensory orofacial disturbances ranging from 9% to 76% of cases.
It has been described that scheduled early physiotherapy reduces these complications.
Before the surgical intervention (T0) the maximum interincisal oral opening measurement, laterotrusion and maximum protrusion will be recorded by digital caliber. The overbite and the overjet, length of upper lip and lower facial third will be measured. The symmetry of the upper lip in a forced smile will be determined. The measurements made at T0 will be repeated at T1 (2 weeks after surgery), T2 (5 weeks after surgery), T3 (9 weeks after surgery), T4 (12 weeks after surgery), T5 (24 weeks after surgery) and T6 (after orthodontic removal).The level of pain during the measurements of the mandibular movements will be recorded in the Visual Analogue Scale, and the self-reported area of the orofacial sensory alterations by means of a diagram and the objective area by means of the sensory discrimination test of two points will be determined. In T4, the impact of the status of the function and oral structures on daily activities will be recorded through a self-pass questionnaire based on the Oral Index Daily Performance questionnaire (OIDP-sp). In the T6 the measurement of laterotrusion, protrusion and retrusion movements measured by Gysi Gothic arch will be performed.
Exclusion Criteria:
Patients will receive basic indications of rehabilitation consisting of daily mobilization of the jaw (perform several movements a day opening movements, laterotrusion and mouth protrusion).
Other: Early Physiotherapy
From T1 to T2 patients will perform 3 daily repetitions of active exercises:1 5 repetitions of oral opening exercises and bilateral manual progressive stretching, protrusion and maximum lateralization of the jaw on both sides, holding each movement for 5s and a session of cryotherapy applied to the masseter, temporal and suprahyoid muscles for 120s in two 60s sessions. They will also perform 30 repetitions of exercises aimed at improving the labial seal (inflate cheeks) and the symmetry of the upper lip (broad smile). From T2 to T3 30 repetitions of the same exercises will be performed and passive progressive opening will be implemented by "clamping" Patients will also perform isometric contraction exercises in opening, closing, laterotrusion, protrusion and retrusion. Each movement will be repeated 5 times and it will remain for 5s.
Pain during mandibular movements
The level of pain during the measurements of the mandibular movements will be registered using a Visual Analogue Scale, in which point 0 represents "no pain" and point 10 "maximum pain". Values under point 5 are considered to represent mild pain and values above point 5 severe pain
Time frame: week 12 (T4)
Maximum interincisor opening
The maximum interincisal oral opening measurement will be recorded by digital caliber
Time frame: week 12 (T4)
Lip symmetry
Lip symmetry will be recorded by facial photography of the patient in broad smile
Time frame: Before OS (T0), week 2 after surgery (T1), week 5 (T2), week 9 (T3), week 12 (T4), week 24 (T5), and after orthodontic removal: up to one year after OS (T6)
Orofacial sensitivity
Self-reported area of orofacial sensory alterations will be measured by means of a diagram and the objective area by means of the sensory discrimination test of two points.
Time frame: Week 2 after surgery (T1), week 5 (T2), week 9 (T3), week 12 (T4), week 24 (T5), and after orthodontic removal: up to one year after OS (T6)
Laterotrusion
The oral laterotrusion measurement will be recorded by digital caliber
Time frame: Before OS (T0), week 2 after surgery (T1), week 5 (T2), week 9 (T3), week 12 (T4), week 24 (T5), and after orthodontic removal: up to one year after OS (T6)
Protrusion
The oral protrusion measurement will be recorded by digital caliber
Time frame: Before OS (T0), week 2 after surgery (T1), week 5 (T2), week 9 (T3), week 12 (T4), week 24 (T5), and after orthodontic removal: up to one year after OS (T6)
Impact of the status of the oral function and structures on daily activities
The impact of the status of the oral function and structures on daily activities will be recorded through a self-pass questionnaire based on the Oral Index Daily Performance questionnaire (OIDP-sp)). In the OIDP index impacts are quantified by multiplying the frequency and severity scores to obtain the performance score for each of eight dimensions (eating, speaking, cleaning teeth, working, social relation, sleeping/relaxing, smiling and emotional status). The sum of these scores is considered the total impact score. This total score is divided by the maximum possible score and multiplied by 100 to give the percentage score. This scoring system yields an intuitive oral impact score.
Time frame: Week 12 (T4)
Functional oral movements - Gysi Gothic arch
The measurement of laterotrusion, protrusion and retrusion movements measured by Gysi Gothic arch will be performed and the functional oral movements capacity will be measured bay the total of millimeters of all movements
Time frame: After orthodontic removal: up to one year after OS (T6)
