Oral Surgery · patient case question
What is the appropriate FIRST line of treatment?
Patient case: Restricted opening with pain only on passive stretch
Patient: Female, 33 years old
Chief Complaint: “My jaw feels tight and I cannot open as wide as I used to.”
Background: Reports a stressful year and daytime clenching. No trauma, no locking episodes, no previous treatment.
Vital Signs: BP 116/72 mmHg · HR 76 bpm
Findings: Maximum comfortable opening 32 mm. On gentle PASSIVE STRETCH the jaw opens a further 5 mm, at which point the patient reports pain. NO pain on lateral or protrusive movements. NO joint noise. Palpation of the masseter and temporalis reproduces her familiar discomfort. Radiographs show no degenerative change.
Show answer and explanation
Correct answer: D. Occlusal splint therapy with patient education and jaw exercises
- A. Arthrocentesis is an INTRACAPSULAR procedure for a joint problem that has failed conservative care. This patient's restriction is muscular, and nothing has been tried yet.
- B. Occlusal equilibration is IRREVERSIBLE. There is no good evidence that grinding teeth treats temporomandibular disorders, and once enamel is removed it cannot be returned.
- C. Orthognathic surgery addresses skeletal discrepancy. It is not a treatment for masticatory myalgia and sits at the very end of any escalation, if at all.
- D. CORRECT. Management of temporomandibular disorders begins with what is REVERSIBLE and CONSERVATIVE: patient education and reassurance, a soft diet and jaw rest, moist heat, gentle stretching exercises, stress and parafunction awareness, and a flat-plane STABILISATION SPLINT worn at night. The great majority of patients improve on this alone. Pharmacotherapy — an NSAID or a short course of a muscle relaxant — is an adjunct, not the foundation.
Note: Sequence every temporomandibular case the same way: reversible first — education, self-care, physiotherapy, splint — then reassess at six to eight weeks; then adjunctive pharmacotherapy or trigger point injection; and only after documented failure of conservative care does anything irreversible come into the conversation. The condition is largely self-limiting, which is precisely why irreversible treatment is so hard to justify early.
