Hyaluronic Acid Evaluation as Adjuvant to Temporomandibular Joint Arthroscopy

Hyaluronic Acid Evaluation as Adjuvant to Temporomandibular Joint Arthroscopy in Wilkes Stages

This study evaluates the addition of hyaluronic acid to temporomandibular joint arthroscopy in the treatment of internal derangements in adults. A participants group will receive temporomandibular joint arthroscopy plus hyaluronic acid, while the other group will receive temporomandibular joint arthroscopy. Hypothesis: hyaluronic acid as an adjunct in temporomandibular joint arthroscopic surgery provides additional benefits in clinical and radiological outcomes in temporomandibular joint internal derangements.

Inclusion Criteria:

• Diagnosis of temporomandibular joint internal derangements in Wilkes stages III and IV by magnetic resonance imaging
• Limitation of maximum oral opening or duplication of joint pain by palpation
• lack of response to conservative therapies

Exclusion Criteria:

• Any degenerative systemic disease of muscular or joint involvement (rheumatoid arthritis, etc.)
• Previous temporomandibular joint surgical treatment: arthrocentesis, arthroscopy or open surgery
• Infection in Temporomandibular Joint or in puncture site
• Hyaluronic acid or corticosteroids injection in Temporomandibular Joint in previous 6 months
• Pregnant or breastfeeding women
• Participants who refuse to complete the treatment or unavailable to complete the follow-up
