Abstract
Temporomandibular joint (TMJ) arthroscopy is a minimally invasive surgical procedure
proposed for diverse TMJ intra-articular disorders. A prospective study was designed
with the aim of investigating intraoperative and postoperative surgical complications
for single and double-portal TMJ arthroscopy. All interventions were performed by
one surgeon with the same surgical protocol. A total of 55 patients were enrolled,
resulting in 82 TMJ arthroscopies (28 unilateral and 27 bilateral). A total of 39
single portal (47.57%) and 43 double-portal (52.43%) arthroscopies were performed.
No severe and irreversible complications were observed. Most complications were resolved
after 4 weeks. Double-portal was associated with more complications (n = 23) compared with single-portal TMJ arthroscopy (n = 14), with a statistically significant difference found between single and double-portal
TMJ arthroscopy in two intraoperative complications: intra-articular bleeding (P = 0.044) and oedema of the preauricular area (P = 0.042). This study confirms the safety of TMJ arthroscopy for single and double-portal
procedures, with the authors suggesting a multicentre study, in an effort to minimize
any possible bias.
