This study aims to evaluate the efficacy of arthrocentesis in the treatment of internal derangement of the temporomandibular joint (TMJ).
This work was designed as a prospective case series clinical study. Patients imaging was evaluated with Cone-Beam Computed Tomography and Nuclear Magnetic Resonance at the beginning of the treatment and after the last arthrocentesis.
Study Type
OBSERVATIONAL
Enrollment
30
lavage of the superior TMJ space with saline and sodium hyaluronate (SH)
Maxillofacial Unit, University of Sassari
Sassari, SS,, Italy
Pain decrease
Patients were followed up for 1 year. The mean pre-operative pain, using visual analog scale, showed an average decrease of 6.7 at 1 year.
Time frame: baseline (preop), 1 week, 1 month, 2 months, 6 months, 12 months (postop)
increase in the mouth opening
The mean maximum mouth opening(MMO) pre-operatively was 15,8 mm and increased to 34 mm immediately following arthrocentesis which increased by 0.5-1 mm at every month followup with mean MMO of 39,4 mm at 6 months. Thereafter it remained consistent till 1 year. The mean increase in the mouth opening at 1 year was 23,6 mm
Time frame: Baseline (preop), 1 week, 1 month, 2 months, 6 months, 12 months (postop)
TMJ click and noises reduction
At the end of 1 year, (75%) patients stated no evidence of clicking.
Time frame: Baseline (preop), 12 months (postop)
number of subjects showing signs of TMJ inflammation or structural alterations at Magnetic Resonance Imaging and Cone Beam Computerized Tomography pre- and postop.
40% of subjects who showed clear signs of inflammation showed significant improvement, in 30% with structural alterations was evident the absence of intra-articular adhesions and debris, in 30% with internal derangement did not appear any radiographic change.
Time frame: Baseline (preop)- 60 days postop
