AI Article Synopsis
- The study developed an MRI evaluation system for managing synovial chondromatosis of the temporomandibular joint (TMJ-SC), focusing on various factors like bone erosion and loose body size.
- Patients underwent different treatments, with 34 having arthroscopy and 161 opting for open surgery, yielding positive outcomes.
- After an average follow-up of 75.1 months, there was significant improvement in joint function, pain levels, and only two cases of tumor recurrence were noted.
Article Abstract
The aim of this retrospective observational study was to introduce a comprehensive MRI evaluation criterion for the clinical management of synovial chondromatosis of the temporomandibular joint (TMJ-SC). Patients received different treatments according to the MRI evaluation system: bone erosion, extent, articular disc condition, location, maturity, and size of loose body. At least a 2-year follow-up was completed to assess tumor recurrence, visual analogue scale score for pain (VAS) and maximum interincisal opening (MIO). Of the 195 patients included for TMJ-SC, 34 received arthroscopy and 161 received open surgery. Among the patients with significant extent of SC, 32 received temporary resection of the condylar neck or zygomatic arch and 2 received treatment combined with ear, nose and throat(ENT). 28 received articular disc reconstruction and 56 received disc repositioning. Patients showed good recovery of joint function with only two cases of tumor recurrence at an average follow-up of 75.1 months after surgery. The MIO had improved from 30.2 mm to 40.0 mm(P < 0.0001) and VAS had decreased from 5.1 to 0.78(P < 0.0001).The preoperative MRI evaluation principles has been effective in selecting appropriate surgical options.

Background: Adolescent females have a high prevalence of temporomandibular joint (TMJ) anterior disc displacement (ADD), which can lead to condylar resorption and dentofacial deformity. Polycystic ovarian syndrome (PCOS) is a common endocrine disorder that disrupts bone metabolism. However, the effects of PCOS on bone remodeling especially after disc repositioning (DR) surgery are not well understood.

The lateral pterygoid muscle (LPM), a critical component of the masticatory muscles, typically comprises upper (SLPM) and lower (ILPM) heads. However, it is essential to note that the LPM's structure is not a constant feature, as the number of bundles and their topography can vary. Moreover, additional heads, such as medial and middle heads, and unique-headed configurations of the LPM have been reported.

The objective of this study was to compare single-needle arthrocentesis with the conventional two-needle arthrocentesis, as well as the additional intracapsular injection of hyaluronic acid or platelet-rich fibrin. A total of 96 patients with established osteoarthritis (OA) ( = 48) or with internal de-arrangement (DD) ( = 48) were assigned single-needle arthrocentesis with distension of the joint or conventional two-needle arthrocentesis with or without intracapsular injection of the medication (hyaluronic acid (HA) or platelet-rich plasma (PRP)) performed every month over a period of 6 months. The maximum mouth opening and pain, as measured by the visual analog scale (VAS), were compared.
