Jaw Region Pain / Hypermobility – Locking Open

Jaw Region Pain / Hypermobility – Locking Open

Case Description: The patient is a 72 y/o female with a ~2 month history of intermittent sharp jaw pain and 5 episodes of an experience described as her jaw “locking open wide” (2 of which had occurred in the week prior to starting PT).  She notes that the episodes happened with wide opening and had occurred with yawning or after opening wide to eat.  Her jaw felt as if it dislocated and on one instance remained locked open for nearly 5 minutes before her husband was able to forcefully shut her jaw.  She was very fearful to open and was restricting her diet and fearful with basic dental hygiene, like brushing her teeth.  

Intervention: The patient was seen for 6 physical therapy visits over 3.5 wks

MobilityTreatment / Function
Initial Evaluation (IE)35+ mm opening, strong L deflection indicating R sided TMJ hypermobilityDiet medication to reduce strain on jaw and reduce need for wide opening.  Education on rest, heat, self-massage to reduce pain
2 week after IE35+ mm, reduced L deflection – apprehension still presentEducation on gradual re-introduction to her typical diet.  Continued modification to yawning to reduce risk of re-injury.  Able to have dental exam without issue. 
3 weeks after IE /Discharge40+ with minimal apprehension, notable reduction in L deflectionAble to resume her normal diet and had no instances of “locking open” for nearly 1 month 

Summary: This patient had classic signs of R sided TMJ hypermobility and resultant subluxation/dislocation as her mandibular condyle progressed beyond her maxillary articular eminence during wide opening.  With technique to reduce inflammation and initially limit instances of wide opening, she was able to go without episode of locking open for the entirety of her care and had tools to continue managing on her own.
