A year-old female patient visited the Department of Oral Medicine and Radiology with a chief complaint of spontaneous, painful constrictive movements on her right side of face with a feeling of constriction in her neck leading to difficulty in breathing.

A comprehensive literature review was done from up to December The dystonic movements diminished with oral sensory feedback such as voluntary opening of mouth by the patient in an attempt to breathe through mouth.
On intraoral examination the episodes began with fine involuntary fasciculations in the right masseter and temporalis which progressed to severe dystonic contractions of the face and neck within few seconds causing grimacing of the face with difficulty in breathing following which the patient assumed a body posture holding the right side of face and neck gasping for breath, trying to open her mouth in an attempt to breath.

It was suggested as an effective and relatively simple modality of treatment.
In the reported case, spasm of lateral pterygoid muscles was revealed by neurologic evaluation, and medication and botulinum neurotoxins BoNT were utilized for relief. The work of several doctors such as Nancy Byl and Joaquin Farias has shown that sensorimotor otomandibular activities and proprioceptive stimulation can induce neuroplasticitymaking it possible for patients to recover substantial function that was lost due to Disyonia Dystonia, oromandibular dystonia and dysphonia.
The complaint of ill-fitting full dentures in these patients should be taken seriously. Disonia and Effects of Oromandibular Dystonia OMD The uncontrollable contractions and movements of this disorder can lead to many side effects.
