DISLOCATION OF CONDYLES/LUXATION OF TMJ

Image source: SlideShare

Let’s first understand the terms Luxation, Subluxation & Habitual Dislocation👇🏻

  • Luxation of joint refers to complete dislocation – Non self reducing.
  • Subluxation is partial dislocation or Self-reducing.
  • Repeated anterior dislocation & self reduction leads to Habitual/Recurrent dislocation.

➡️ Condylar dislocations can be divided into Anterior (Luxation/Subluxation), Cranial & Posterior Dislocations.

Etiology:

  1. Fracture of condyle (due to acute trauma)
  2. Stretching of capsule of TMJ
  3. Yawning/mouth opened too widely (during extraction/ Tonsillectomy/ Endoscopy)

Clinical Features:

  1. Sudden locking & immobilization of jaw when the mouth is open. Hence mouth cannot be closed and patient becomes panicky.
  2. Spasmodic contractions of Temporal, internal pterygoid & masseter muscle with protrusion of jaw.
  3. Severe pain, excessive salivation & depression of skin around preauricular area
  4. Eating/talking – impossible.

Treatment:

  1. Relaxation of Muscles – Inferior & superior pressure of thumbs in mandibular molar area.
  2. General anesthesia
  3. Tiring the masticatory muscles: Cupping the chin in palm of hand & applying pressure 5-10 min.
  4. Recurrent Dislocation – Alter the ligament, bony musculature.
  5. Repositioning Dislocated Temperomandibular Joint..Do watch till the end! (Video credits: Youtube channel-The General Medicine)👇🏻
