Arthroscopy of the temporomandibular joint: Discopexy with resorbable pins

Introduction:
Since early 80s, arthroscopy of the temporomandibular joint has been a Minimal Invasive Surgery (MIS) that effectively
treats some intraarticular TMJ diseases. Nowadays, its interest among oral and maxillofacial surgeons is increasing but there is a
lack of a complete training program, except in few places. This unique procedure allows surgeons to manage different diseases that
include, synovitis, chondromalacia, adhesions, disc perforations and disc displacement. Also, beneficial substances, as PRP, hyaluronic
acid and botulinum toxin can be instilled. This masterclass tries to help surgeons who are starting with the technique, giving them
several tips to succeed and showing different pitfalls to avoid, based on the author’s own experience in over 700 procedures. Further
information will be helpful for the experienced surgeon and very innovative variation in standard techniques (i.e., discopexy with
resorbable pins) will also be analyzed through educative videos.
Purpose:
To describe the use of resorbable pins for disc fixation in a series of patients and their medium- long term outcomes.
Materials and methods:
A study was conducted in 26 patients who underwent operative arthroscopic surgery and discopexy using
resorbable pins. All patients were refractory to conservative treatment and presented, in at least one joint, anterior disc displacement
without reduction on Magnetic Resonance Imaging (MRI). Pre- and postoperative evaluation parameters were disc position on MRI,
maximal interincisal opening, lateral movements, joint pain, and articular locking and clicking.
Results:
The technique was performed in 34 joints and 47 pins were inserted. Mouth opening increased significantly, from a mean
of 31.24 mm preoperatively to 39.57 mm in one year postoperatively (p<0.05). Patients reported a decrease in pain, obtaining values
on a visual analogue scale (1e100) of less than 20 after one year of post-surgery (mean improvement 47.9 points, p<0.05). Analyzing
one-year MRI findings, in 65% of joints the discs were repositioned and in 20% of joints discs were in a more posterior position. Five
years later results are also shown.
Conclusions:
The use of resorbable pins is a useful technique for disc fixation and shows medium-long term improvement in clinical
parameters and mandibular function. However, further studies are needed to evaluate a longer follow-up, joint morphologic changes,
and disc stability on imaging
