Condylar process fractures remain a matter of ongoing controversy in maxillofacial surgery because of variety of opinions and proposed treatment modalities offered in the literature. The trend is toward open reduction and internal fixation (ORIF) whenever there is displacement or dislocation combined with unstable occlusal conditions. The fundamental treatment goals are anatomical fixation and early return to function.

Temporomandibular joint (TMJ) surgery in China, as an important part of oral and maxillofacial surgery, has made significant progress in the past 20 years. It is mainly reflected in the reduction of TMJ dislocated joint disc, prosthetic total TMJ reconstruction, and the treatment of adult condylar fracture. There are major controversies about the surgical methods and indications for the reduction of the dislocated/displacement joint disc of the temporomandibular disorders.

The experience of chronic protracted mandibular dislocation treatment: manual vs. surgical reduction.

BMC Oral Health

September 2024

Key Laboratory of Shaanxi Province for Craniofacial Precision Medicine Research, College of Stomatology, Xi'an Jiaotong University, Xi'an, China.

Temporomandibular joint dislocation is a common challenge in dental care, but it can be promptly addressed through manual realignment, making it standard procedure in the realm of oral health. Nonetheless, effectively preventing and treating chronic protracted mandibular dislocation (CPMD), characterized by prolonged dislocation, remains a significant challenge. Hence, a retrospective analysis was conducted on the clinical data of 10 patients diagnosed with chronic protracted mandibular dislocation (CPMD), encompassing diagnosis, treatment, and prognosis details.

Dislocation of the mandibular condyle of the temporomandibular joint (TMJ) is defined as a clinical condition in which head of the condyle is displaced out of its functional position within the glenoid fossa and posterior slope of the articular eminence Allen and Young in Br J Oral Surg 7:24-30, (1969). Dislocation of the mandibular condyle most commonly occurs in the anterior or anteromedial direction in both traumatic and non-traumatic origin dislocations. Lateral dislocations are generally rare owing to the thickening of the lateral surface of the articular capsule by the lateral ligament that strengthens the lateral surface of the joint Lovely and Copeland in J Can Dent Assoc 47:179-184, (1981).

Introduction: Anterior displacement of the temporomandibular joint (TMJ) disc is a disorder in which the articular disc is dislocated from its correct position relative to the mandibular condyle and mandibular fossa. Traditionally, the initial treatment of disc displacements involves various conservative measures, including the use of a stabilizing interocclusal splint. However, in cases where there is associated limited mouth opening, as in the case of anterior disc displacement with reduction and intermittent block (ADDwRIB), and anterior disc displacement without reduction (ADDw/oR), arthrocentesis has been suggested as another modality of initial treatment due to its faster effect in preventing disease progression to a more advanced stage, as well as reducing the chances of pain chronification and central sensitization.

Arthrocentesis versus occlusal coverage splints in the management of disc displacement without reduction: a systematic review and meta-analysis.

Int J Oral Maxillofac Surg

Oral and Maxillofacial Surgery Department, Royal Preston Hospital, Lancashire Teaching Hospitals Trust, Fulwood, Preston, Lancashire, UK.

Disc displacement without reduction (DDwoR) can cause pain and limitations in mouth opening, with a significant impact on function. The optimal management strategy for DDwoR is unclear. Treatments include conservative management such as mandibular manipulation, occlusal splints, and patient education/self-management, as well as arthrocentesis, which is a minimally invasive procedure.

Article Synopsis
  • The study aimed to examine how different types of disc displacement (DD) in Temporomandibular disorders (TMD) patients relate to the risk and severity of condylar erosion (CE) as seen in MRI and CBCT scans.
  • The research involved 353 TMD patients, categorizing their DD and grading CE severity, using logistic regression to analyze data while accounting for variables like age and gender.
  • Results showed that anterior displacement without reduction (ADDNR) significantly increased the risk and severity of CE compared to normal displacement, while anterior displacement with reduction (ADDR) was mostly linked to mild CE, particularly affecting females more.
