Severe trismus and contraindicated exodontia in a patient with fibrodysplasia ossificans progressiva: case report.

Fibrodysplasia ossificans progressiva is a rare genetic disease of connective tissue in which muscles, ligaments, and tendons ossify either spontaneously or after trauma. Patients can develop physical disabilities and restriction of respiratory function. A patient attended a maxillofacial surgery outpatient clinic with severe trismus and mouth opening limited to 2mm. The risks of intervention were many from both anaesthetic and surgical perspectives, which prevented the extraction of carious teeth. The patient was referred to a special care dentistry team who provided endodontic stabilisation without local anaesthesia. In the case of severe infection, surgical intervention would be challenging to justify.
