“…Four therapeutic case studies were included. In all of these studies, a substantial increase in mouth opening was reported, ranging from 17 to 24 mm . In a prospective study, Pauli et al found a significantly larger increase (a difference in mean increase of 6.4 mm) in the exercise intervention group compared to the control group ( p < .001).…”

Background. Effects of exercise therapy for trismus secondary to head and neck cancer have not been reviewed systematically since 2004. Methods. Four databases were searched. The quality of observational studies and randomized controlled trials was assessed. Results. Two hundred eleven articles were found, 20 studies were included. A large variation in research methodology, stretching techniques, duration of stretch, and repetition of exercises was found. The overall quality was moderate. Five of the 8 preventive studies found that exercises during (chemo)radiotherapy could not prevent a reduction in mouth opening. In 4 therapeutic case studies, mouth opening increased between 17 and 24 mm. In 8 other therapeutic studies, mouth opening increased between 21.9 and 13.6 mm. No exercise therapy was clearly superior to the others. Conclusion. Changes in mouth opening ranged considerably and no stretching technique was superior to others regarding either prevention or treatment of trismus. Clinical guidelines cannot be given based on this systematic review.

“…During data extraction, we found that 6 studies had premeasurements and postmeasurements of the mouth opening taken, but data (premeasurement and postmeasurement mean [SD] of mouth opening) were not provided. Therefore, these studies were excluded . A seventh study was excluded because it analyzed the effects of pentoxifylline on mouth opening .…”

“…In July 2014, the searches were updated and 3 new studies were included for qualitative assessment. In total, 20 studies were included in this review: 4 case studies, 6 prospective studies, 5 RCTs, and 5 patient chart studies (Table ). The sample sizes ranged from 1 to 108 patients, with a mean age ranging from 13.0 to 63.3 years.…”

“…Many (unusual) stretching techniques have been described in case reports and case series. A sledgehammer, tied to the mandible for 2 min twice a day, resulted in an increase in mouth opening of 18 mm [10], An orthodontic “clothes pin appliance” inserted between the molars and thereby stretching mouth opening resulted in an increase of 6 mm [11]. Further, application of a surgical mouthprop, a tapered screw, a screw-type mouth gag, fingers, tongue depressors, an intraoperatively fabricated self-curing bite block, and interarch springs attached between maxillary and mandibular restorations have been described as methods to improve mouth opening but without providing information about the actual increase in mouth opening [12–16].…”

PurposeThe aim of this study was to evaluate the effect of TheraBite exercises on mouth opening and to analyze factors influencing this effect in a patient record evaluation.MethodsEffect of exercises with a TheraBite to treat trismus was evaluated in 69 head and neck cancer patients of two university medical centers. Mouth opening was measured as interincisal distance in millimeters. Patient, tumor, and treatment characteristics were analyzed for their relationship with change in mouth opening. Variables univariately associated (p ≤ 0.05) with change in mouth opening were entered in a logistic regression analysis as possible predictors for an increase in mouth opening of the smallest detectable difference of 5 mm or more.ResultsMean initial mouth opening was 22.0 mm (SD 6.4); mean increase in mouth opening was 5.4 mm (SD 5.7). “Chemotherapy”, “medical center”, and “time from oncological treatment to start exercises” were significantly associated with an increase in mouth opening. In the logistic regression analysis, “medical center” (β = 1.97) and “time from oncological treatment to start exercises” reduced the odds of reaching an increase in mouth opening of 5 mm or more, β = −0.11 per month.ConclusionsAfter TheraBite exercises, mouth opening increased averagely with 5.4 mm. The odds of an increase in mouth opening of 5 mm or more reduces if the time from oncological treatment to start exercises lengthens, corrected for the effect of medical center.
