Physiotherapy Maneuver Is Critical to Recover Mouth Opening After Pediatric Trauma.

Purpose: A restricted mouth opening (MO) is predominantly a complication of maxillofacial trauma in pediatric patients and develops in 4 to 26.2% of cases. The purpose of the present study was to quantitatively investigate the influence of patient demographic data, fracture characteristics, and regular vigorous physiotherapy, with either voluntary or forcible MO exercises, on the recovery of a post-traumatic restricted MO in pediatric patients.
