Abstract:
Orofacial complex regional pain syndrome (O-CRPS) presents a diagnostic challenge due to its overlap with other orofacial pain conditions. This case report highlights the value of a multidisciplinary approach in managing a patient with chronic and unexplained facial pain.This case report aims to illustrate: (1) the application of a multidisciplinary approach in diagnosing and managing O-CRPS within the Saudi healthcare system, and (2) the effectiveness of the Self-Training Educative Pain Sensation (STEPS) model in managing O-CRPS.
Case Description:
A woman in her early 20s presented with left-sided facial pain and motor/autonomic symptoms following a facial injury. Extensive evaluations by various specialists excluded underlying structural pathology. A diagnosis of O-CRPS was established based on Budapest criteria. The STEPS model was implemented for treatment.
Intervention:
The STEPS model, a four-component intervention (pain education, graded motor imagery, sensory exposure, facial muscle exercises), aimed to reduce allodynia, normalise motor control and restore important functional activities.
Outcomes:
Initial pain medications were ineffective. The STEPS model intervention significantly improved pain, function and overall quality of life.This case report emphasises the importance of a multidisciplinary approach to diagnosing O-CRPS and the potential benefits of the STEPS model in managing this complex condition.
