This case is designed for Allied Health professions students in the 2nd or 3rd year of their program (dentistry, nursing, medicine).
By the end of this iPBL activity of Facial Pain, learners will be able to stepwise manage the patient with the following clinical objectives:
- List and interpret the important clinical findings, including history and physical examination with emphasis on the following:
- Review of the pain history (including past treatments), psychosocial and other functional impairment.
- Identify signs of neurological impairment and other differential causes of pain or numbness for e.g. vascular insufficiency;
- List and interpret possible appropriate investigations which may include:
- Screening investigations for underlying medical conditions (e.g., fasting glucose, chest X-ray);
- Nerve conduction studies;
- Vascular studies;
- Construct an effective initial management plan, including:
- Discussing possible drug options;
- Counselling, including prevention of progression (e.g., chronicity of symptoms, exercise, activity modification);
- Optimal treatment of any underlying medical conditions (e.g., diabetic management);
- Determining whether the patient needs a referral to a pain clinic or pain specialist.

A note on the role of the facilitator:
“The teacher (facilitator) serves as both a monitor and stimulus to the process by asking leading questions, challenging thinking and raising issues or points that need to be considered. The teacher (facilitator) attempts to help students help themselves in the educational process” (Barrows & Tamblyn, 1980)
Day 1, Part 1:
Jane, a 52-year-old married woman, awoke one morning with a sharp shooting pain in her right eat that expanded to the lower part of her face. As the morning progressed the pain worsened, varying in severity and length. She described that the pain “felt like an electric shock”. She had never experienced this type of pain before. She took 600 mg of Ibuprofen with no relief. She considered herself healthy with the only significant family history of hypertension and one aunt with Relapsing-remitting Multiple Sclerosis (RRMS).
She went to her family physician, Dr. Tong, who completed a quick otoscopic exam. Although nothing appeared abnormal on the exam, Dr. Tong prescribed a course of Ciprodex ear drops to be taken four times a day for 7 days. After returning home from Dr. Tong’s office, Jane was very uncomfortable. She called Dr. Tong’s office the following day and explained that her pain had amplified. The pain would trigger while touching the skin on the right side of her face around the lips and cheek and would last for a few seconds. She was not able to wash her face or apply makeup. The office staff stated that Dr. Tong was fully booked for the rest of the day, but her practice partner Dr. Patterson was available at 4 pm.

Day 2, Part 2:
The following week, Jane visited Dr. Sara, an Oral Surgeon, who made her comfortable and listened carefully to what she had to say about her ordeal with the pain and the multiple visits to the GP. Dr. Sara performed an intraoral exam, a Temporomandibular Joint (TMJ) exam, and obtained a panoramic radiograph. Jane had one very small Class 1 cavity which was painless on probing and percussion and her TMJ was slightly stiff with tenderness in the masseter and angle of the mandible. The panoramic radiograph showed no abnormalities.
Dr. Sara also conducted an extraoral examination of the face and found trigger zones that elicited the sharpshooting, stabbing pain Jane had described. The trigger zones were on the right cheek, right nostril, and upper lip. She then advised an MRI scan to rule out MS and prescribed Carbamazepine 50 mg four times a day till the MRI scan results were available.
A few weeks later, Jane had a follow-up appointment with Dr. Patterson to review the MRI results, which showed no evidence of intracranial lesions but noted a suspected vascular compression of the superior cerebellar artery. Dr. Patterson diagnosed Jane with Trigeminal Neuralgia, suspecting the etiology was related to the vascular compression noted on the MRI. Dr. Patterson contacted the neurologist’s office to make an urgent referral for Jane and adjusted the dosage of Carbamazepine to 100 mg twice a day, pending further treatment advice.

- How does having to wait for test results affect patient’s psychological health?
- In some provinces, electronic health systems allow patients to access their test results as soon as they are available on the EMR system (i.e. MySaskHealthRecord). What impact do you think this will have on patients’ health? What impact will this have on the patient’s relationship with the health care system?
- When should Jane follow-up with Dr. Sara?
- Are there non-medical options to help treat Jane’s pain?
- What obstacles prevent patients from being able to take medications as prescribed?

- What structures does the superior cerebellar artery supply? Can you explain the pathophysiology of Jane’s symptoms?
- Are there surgical options to treat a vascular compression?
- How should Jane be counseled so that she can avoid possible progression of her illness?
- How do you determine whether a patient needs a referral to a pain clinic or pain specialist?
