TMJ pain and cryoanalgesia

Area of Science:

• Oral and Maxillofacial Surgery
• Pain Management
• Orthodontics

Background:

• Temporomandibular joint (TMJ) pain is multifactorial, encompassing myofascial pain, internal derangement, and degenerative conditions.
• Psychological factors significantly influence temporomandibular disorders (TMD).
• Standardized protocols aid TMD assessment, but complex cases require addressing multiple disease processes.

Purpose of the Study:

• To outline a management strategy for temporomandibular joint (TMJ) pain.
• To emphasize conservative and non-invasive initial treatments for TMD.
• To detail diagnostic and therapeutic interventions for joint-related TMJ pain.

Main Methods:

• Initial management focuses on conservative, non-invasive, and evidence-supported measures.
• Myofascial pain may be treated with tricyclic antidepressants or botulinum injections.
• Joint pain diagnosis involves assessing pain relief after intra-articular local analgesia (LA).

Main Results:

• Arthroscopy/arthrocentesis successfully relieve pain in up to 90% of cases where LA is effective.
• Arthroscopy serves as an accurate diagnostic tool for TMJ disorders.
• Surgical interventions like open surgery have lower success rates, with joint replacement as a final option.

Conclusions:

• Conservative management is the cornerstone of initial TMJ pain treatment.
• Intra-articular LA is crucial for diagnosing joint-related pain and guiding subsequent interventions.
• Minimally invasive procedures like arthroscopy offer high success rates for TMJ pain, while cryoanalgesia may benefit select cases.
